Steel conveyor belt pulleys are critical to the design of any automated conveyor belt program. They become the driving power behind the movement of the belt, creating torque and swiftness. In very general terms it can be said that pulleys are categorized as friction drive or timing pulleys (type I and II). Precision is the name of the game when it comes to pulleys. A metal belt is as good and specific as the pulleys. Many pulleys suggested by Ever-power are made of anodized aluminum (hard coating) with the right friction coefficient to operate a vehicle the metallic belt. Stainless steel may also be used nonetheless it is expensive and heavy, though it might end up being indicated using applications where extra hardness is necessary. If your application takes a lighter pulley, the experts at Ever-power can help you choose the best material.
Selecting the right pulley size and configuration can have a substantial effect on the lifespan and performance of a conveyor belt. Ever-power engineers have the data and experience to help you choose the right pulley type, diameter, and composition to reduce maintenance downtime and increase product volume.
Steel Conveyor Belt Pulley Types
Ever-power designs custom metallic conveyor belt pulleys and configurations to bring maximum efficiency to one’s body. While steel conveyor belts are typically made of stainless steel, pulleys can be produced from a number of materials, including light weight aluminum or a number of plastic composites. Depending on the unique needs of one’s body, the pulleys may also be fitted with custom timing attachments, relief stations, and more.
Independently Steerable Pulley
Ever-power has developed a forward thinking concept in flat belt tracking called the ISP (independently steerable pulley), which can be used in the following system designs:
· Two pulley conveyor systems where the ISP may be the idler or driven pulley
· Systems with multiple idler pulleys on a common shaft
· Systems with serpentine or various other complex belt paths
Steering toned belts with an ISP is founded on the idea of changing tension interactions over the width of the belt by adjusting the position of the pulley in accordance with the belt.
Instead of moving the pulley shaft still left/right or up/straight down by pillow prevent adjustment, the ISP fits a variable steering collar and sealed bearing assembly to your body of the pulley.
The steering collar is designed with either a skewed or an offset bore. When rotated, the collar changes the position of the pulley body, leading to controlled, bi-directional movement of the belt over the pulley face.
The ISP is exclusively available from Ever-power. It offers a simple approach to steering flat metal belts. Users may combine ISP steering with the original belt tracking styles of crowning, flanging, and timing components to make a synergistic belt tracking system which efficiently and exactly steers the belt to specified tracking parameters.
Unique Characteristics and Advantages of the ISP
· Flat belts are tracked quickly by rotating the steering collar.
· ISP designs minimize downtime when changing belts on production machinery.
· ISP system is simple to use and needs simply no special tools or training.
· ISP simplifies the look and assembly of conveyor systems using smooth belts.
· Existing idler pulleys can normally be retrofitted to an ISP without major system modifications.
· No maintenance is required once the belt monitoring parameters have already been established.
· It prolongs belt lifestyle by minimizing side loading when using flanges and timing pulleys.

Installation and Use
The ISP is mounted to the machine frame using commercially available pillow blocks. A clamp can be used to avoid the shaft from turning.
The Rotated Shaft Method of ISP Flat Belt Tracking
· Is used with systems having a single pulley on the shaft.
· Is ALWAYS used when the pulley body is definitely a capped tube style.
· Is NEVER utilized when multiple pulleys are on a common shaft.
· Used selectively when the ISP is a steering roll in a multiple pulley system.
Secure the ISP to the shaft using the split collar and locking screw included in the ISP. Rotate the shaft and collar as a device. When the required tracking characteristics are obtained, avoid the shaft from rotating by securing the shaft clamp. The pulley body will today rotate about the bearing included in the ISP assembly. This method allows the belt to end up being tracked while operating under tension.
Protected the ISP to the shaft using the split training collar and locking screw built into the ISP. Rotate the shaft and collar as a unit. When the required tracking characteristics are obtained, prevent the shaft from rotating by securing the shaft clamp. The pulley body will at this point rotate about the bearing built into the ISP assembly. This method allows the belt to be tracked while working under tension.
The Rotated Collar Approach to ISP Flat Belt Tracking
· Used to individually adjust each belt/pulley combination whenever there are multiple pulleys on a common shaft.
· Utilized when systems have a cantilevered shafting typical of serpentine and various other complex belt path systems. It is suggested that these changes be made only when the belt is at rest.
Fix the shaft via the shaft clamp, loosen the locking screw of the steering collar, and rotate the steering collar about the shaft. When the desired belt tracking features are obtained, secure the locking screw.

System Configuration
Number 1 1 – The drive pulley is a friction drive pulley.
· The ISP is definitely a friction-driven pulley. This configuration is certainly specified for a monitoring precision of 0.030″ (0.762 mm) or greater.
· Teflon® flanges are attached to the pulley body to establish a lateral constraint. The steering feature of the ISP is utilized to set one edge of the belt against the flange with minimal side-loading to the belt.
System Configuration
Number 2 2 – The drive pulley is a timing pulley.
· The ISP is a friction driven pulley. The teeth of the drive pulley and the perforations of the belt set up a lateral constraint. The steering feature of the ISP is used to reduce side-loading of the belt perforations. Tracking accuracy is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for metallic belt systems.
OR
· The ISP is definitely a timing pulley. The teeth of the ISP and the perforations of the belt are utilized for precise tracking control of the belt with the steering feature of the ISP utilized to minimize part loading of belt perforations. Again, tracking accuracy is usually 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Take note: Although it is generally not recommended to have timing elements in both drive and driven pulleys, this style can be used selectively on metallic belt systems with long middle distances between pulleys and in applications where particulate accumulation on the surface of the pulley consistently changes the tracking feature of the belt.
