พูลเลย์ไทม์มิ่งแบบรูตรง EP-H100 ขนาด 12.7 มม. ทำจากเหล็กและเหล็กหล่อ

The H100 พูลเลย์ไทม์มิ่งแบบรูตรง series covers 43 distinct part numbers from 14 H 100 (Dp 56.60 mm) through 156 H 100 (Dp 630.64 mm), providing a drive ratio range from approximately 1:11.1 to 11.1:1 within a single pitch and belt-width combination. This exceptionally broad range is particularly valuable for heavy industrial conveyor systems, where the required speed ratio may be very high — driving a slow-speed indexing conveyor from a high-speed motor — and achieving this ratio in a single belt stage avoids the mechanical complexity and space requirement of multi-stage gearbox or intermediate shaft arrangements. No other standard H pitch tooth count range in the H100 series requires the designer to switch pitch families to achieve the required output speed.

The material progression in the H100 series — medium-carbon or alloy steel for the smaller tooth counts and grey cast iron for the larger — matches material properties to the load and speed conditions at each size. Steel pulleys in the 14–48 tooth range operate at the higher peripheral speeds where the higher tensile strength of steel provides better fatigue resistance at the tooth roots and a harder bore surface that resists keyway fretting under the higher cycling rates of faster shafts. Cast iron pulleys in the 58–156 tooth range operate at lower peripheral speeds where the higher damping capacity of grey cast iron reduces vibration and noise in the heavy, slow industrial drive systems where large-diameter pulleys are deployed. The cast iron's excellent castability also makes the arm-spoked geometry of large-diameter pulleys more economical to produce than equivalent steel weldments.

The H pitch 12.700 mm tooth spacing provides substantially greater belt tooth engagement load capacity than XL pitch (5.08 mm) or L pitch (9.525 mm) at the same belt face width. The larger tooth pitch produces a proportionally larger and stronger tooth root cross-section, distributing the tangential belt load across a greater material cross-section and providing higher fatigue life at heavy cyclic loading. For the heavy industrial applications — aggregate conveyor drives, textile machinery main drives, wood processing equipment, and packaging line main drives — where the H pitch class is most commonly specified, the higher power capacity per belt width unit directly reduces the number of belt strands or belt widths needed to transmit the required power, simplifying the drive design and reducing the pulley face width requirement.

The engineered progression through four structural types — 6F solid flanged (14–35 teeth), 6WF wide web with flanges (36–48 teeth), 6W wide web plain (49–52 teeth), and 6A arm-spoked (58–156 teeth) — provides the optimal structural configuration at each size rather than applying a single design approach across the entire tooth count range. Type 6A arm-spoked large-diameter straight bore timing pulleys reduce the mass compared to equivalent solid disc construction by 40–60%, which meaningfully reduces bearing loads and motor starting inertia at shaft positions carrying these large timing pulleys in heavy industrial drive systems. The flanges on Types 6F and 6WF provide physical belt containment for the belt sizes and misalignment tolerances typical of industrial drives, while the plain Types 6W and 6A rely on the belt's natural stiffness and improved alignment accuracy achievable at the larger diameters.

The H pitch and its dimensional specifications are defined in ANSI/RMA IP-24 and ISO 5294, which are recognized standards in North America, Europe, Japan, and across the Asia-Pacific industrial market. This standardization means that H pitch belts to replace worn belts are available from multiple manufacturers in every major industrial market, eliminating the sole-source dependency that proprietary non-standard tooth forms create. For plant maintenance engineers at industrial facilities in Germany, Australia, South Korea, Brazil, and India — who must source replacement พูลเลย์สายพานไทม์มิ่ง components and belts locally to maintain unscheduled downtime at minimum — the global availability of H pitch belt and pulley stock is a fundamental reliability advantage over proprietary drive system standards.

Aggregate screening plants, mining conveyor systems, and bulk grain handling facilities use H pitch พูลเลย์ไทม์มิ่งแบบรูตรง drives to index conveyors at precise intervals, synchronize multiple conveyor lanes, and drive metering feeders where the feed rate accuracy determines process output quality. The cast iron large-diameter H100 pulleys (60–156 teeth, Dp 242–630 mm) provide the high speed ratio achievable in a single belt stage that eliminates intermediate shafts in the drive train, reducing the total mechanical complexity and failure point count in these remote, difficult-to-service locations. H pitch timing drives are preferred over V-belt alternatives in these applications specifically because belt slip — which is inevitable in V-belt drives under shock loading or belt contamination — causes conveyor indexing errors that disrupt process flow.

Textile looms, yarn processing equipment, and fabric manufacturing machinery require perfectly synchronous drives between the various stations — heddle frame drives, shuttle insertion mechanisms, take-up rollers, and warp beam — where any speed variation between stations causes weave defects in the finished fabric. H pitch พูลเลย์ไทม์มิ่งแบบรูตรง systems provide the synchronous drive characteristic required, with the 12.700 mm pitch's higher power capacity per belt width allowing narrower drive packages within the compact machine frames of modern high-speed weaving equipment. The steel small-tooth-count H100 pulleys (14–20 teeth) are common at the high-speed motor input positions in textile machinery drive trains serving the major textile manufacturing regions in South Asia, Southeast Asia, and Turkey.

High-speed packaging lines — form-fill-seal machines, cartoning equipment, case packers, and pallet wrappers — use H pitch synchronous drives for their main line shaft drives where the constant velocity ratio between motor and all product-handling stations determines package dimensional accuracy and sealing quality. The H100 พูลเลย์ไทม์มิ่งแบบรูตรง in steel (24–35 teeth) is commonly used at the main drive distribution shaft positions in European and North American packaging machinery, where packaging machine OEMs specify H pitch as the preferred main drive standard for medium and large format machines above 10 kW motor power. ANSI/ISO H pitch interchangeability ensures that production facilities in the United States, Germany, Italy, Japan, and Australia can source replacement belts locally for scheduled maintenance.

Sawmill infeed systems, wood chipper drives, planer main drives, and CNC wood routing systems all rely on H pitch synchronous belt drives at the positions where positive speed synchronization between tool and workpiece feed matters for cut quality and tool life. The larger cast iron H100 pulleys (70–120 teeth) appear at the driven shaft positions in main drive applications where the motor runs at standard speed and the required tool shaft speed is substantially lower — demanding high speed reduction in a single stage that only the wide tooth count range of the H100 series provides. Wood processing equipment in Canada, Scandinavia, Russia, and Brazil uses H pitch drives extensively for their combination of high power capacity, ANSI/ISO standardized belt availability, and resistance to the sawdust contamination that prematurely wears V-belt drive grooves.

Web offset and sheet-fed printing presses use H pitch synchronous belt systems on their line shaft drives — the central drive shaft that synchronizes all printing units, impression cylinders, and delivery sections at the same peripheral speed. The H100 steel พูลเลย์ไทม์มิ่งแบบรูตรง (24–48 teeth) is the drive standard for main line shaft positions in medium-format printing presses operating in the 10,000 to 25,000 sheets per hour production range, where the absolute requirement for zero slip between printing units is the determining factor in drive type selection. A timing belt pulley replacement at a printing press main drive position must replicate the original tooth count exactly to preserve the registration relationship between printing units — the H100 series' comprehensive tooth count range ensures the correct replacement is always available.

ANSI/RMA IP-24 is the primary dimensional standard for H pitch synchronous belt drives in the North American market, specifying pulley tooth form, pitch circle diameter calculation, belt dimensional requirements, and drive power rating methods. The H100 series is fully dimensioned to IP-24 specifications, ensuring interchangeability of belts and pulleys between IP-24-compliant products from any manufacturer. North American machine builders in packaging, food processing, wood products, and aggregate industries who specify H pitch พูลเลย์ไทม์มิ่งแบบรูตรง drives reference IP-24 in their component procurement specifications.

ISO 5294 (pulleys) and ISO 5296 (belts) cover the H pitch family in the international standards framework, with dimensional specifications equivalent to ANSI/RMA IP-24. European, Japanese, Australian, and South Korean machine builders reference ISO 5294 in their mechanical drive component specifications. Metric timing belt pulleys and ANSI-standard pulleys in the H pitch overlap dimensionally at the ISO 5294 / ANSI IP-24 boundary — H pitch is a shared standard across both frameworks, simplifying global procurement for multinational machine builders whose product platforms are sold across different regional markets.

Drive components incorporated into CE-marked machinery for European markets must meet the essential health and safety requirements of the Machinery Directive, including adequate design safety factors for power transmission components. The H pitch พูลเลย์ไทม์มิ่งแบบรูตรง should be selected with appropriate service factor applied to the rated drive power to ensure that belt and pulley fatigue life is adequate for the machinery's designed service life. Technical file documentation for CE-marked machinery typically includes drive component specifications confirming that the design load is within the rated capacity of the belt and pulley combination selected.

The Chinese national standard GB/T 11362 covers synchronous belt pulleys for the domestic Chinese industrial market, with H pitch dimensional requirements aligned with ISO 5294 and ANSI/RMA IP-24 to facilitate China timing pulley export. Machine builders in China's manufacturing sector — automotive suppliers, appliance manufacturers, packaging machine OEMs, and industrial automation integrators — specify H pitch timing drives for the same heavy-duty applications as their counterparts in other markets, and the GB/T standard alignment ensures dimensional compatibility with the global synchronous belt drive ecosystem.

In many heavy industrial drive systems, a V-belt first stage handles bulk power transmission from the motor to an intermediate shaft, and an H pitch synchronous second stage drives the process equipment at controlled speed ratio from the intermediate shaft. Our range of V-belt pulleys — SPA, SPB, SPC, SPZ groove profiles in cast iron, steel, and aluminum — provides the first-stage component that pairs with the H100 พูลเลย์สายพานไทม์มิ่ง second stage in these multi-stage drive architectures. Both products share dimensional compatibility at the intermediate shaft through standard bore and keyway specifications, ensuring clean mechanical integration in the combined drive system.

Metric Pitch Standard Toothed Bars provide the linear rack equivalent used in conjunction with circular timing pulleys to produce linear motion from a rotary drive. In automated assembly lines, linear conveyor systems, and industrial gantry mechanisms that combine the rotary timing drive of the H100 pulley with a linear rack stage, both components must share the same pitch for correct mesh. Our toothed bar range covers the metric pitch standards that pair with our H pitch พูลเลย์ไทม์มิ่งแบบรูตรง range in these hybrid drive architectures, providing design engineers with the combined rotary-and-linear drive component sourcing needed for complete linear motion system design without requiring multiple specialized suppliers.
