Gearboxes and velocity reducers are mechanical rate reduction equipment used in automation control systems.

Speed reducers are mechanical products generally used for two purposes. The principal use is certainly to multiply the amount of torque produced by an input power source to raise the amount of usable work. They also Variable Speed Gearbox reduce the input power source speed to achieve desired output speeds.

Gearboxes are used to increase torque whilst reducing the swiftness of a prime mover output shaft (a motor crankshaft, for instance). The result shaft of a gearbox rotates at a slower price than the input shaft, and this reduction in speed produces a mechanical advantage, increasing torque. A gearbox can be set up to accomplish the opposite and offer an increase in shaft rate with a reduced amount of torque.

Enclosed-drive speed reducers, also referred to as gear drives and gearboxes, have two primary configurations: in-line and right angle which use various kinds of gearing. In-line versions are commonly made up of helical or spur gears, planetary gears, cycloidal mechanisms, or harmonic wave generators. Right angle designs are usually made with worm gearing or bevel gearing, though hybrid drives are also obtainable. The type of program dictates which speed reducer design will best fulfill the requirements.
D- Drive is a variable rate geared motor, robust step less unit ideal for different industrial applications.The unit is made to provide low output speed at corresponding high output torque. The drive unit is produced from standard components and comprises of AC squirrel cage engine, variable speed drive and gearbox with case hardened profile ground helical gears. It can be very easily adapted to any machine style. The machine is very compact and save time and money because they are ready to match drive modules. The interior part of the drive is the variable acceleration pulley enclosed in a housing and connected to the gearbox and engine. The speed variation may be accomplished through a hand wheel. Average life to be expected is about 10 years before major maintenance. Belt life would depend on app and environment. General experience is about 3 to 4 4 years life.
The Ring-cone is a mechanical adjustable speed drive utilizing a ring and cone friction power train – therefore the name. The inner drive assembly consists of an input disc, a set of planetary cones, a control band, the cam disc and a pressure control cam. The Ring-cone offers different sizes to handle engine power ranging between 1/4HP – 20HP, and nominal result torque ratings spanning 15 – 130,000 in-lbs. This unique drive provides a speed range of 0 – 800 RPM, and a cam mechanism that adjusts to the environment downstream and may withstand a certain amount of shock load.

With a variable frequency drive, the output torque continues to be continuous from base speed right down to the lower limit, whatever it might be for the application. However, with the Ring-cone mechanical variable speed drive the output torque boosts as the swiftness drops. At the reduced speed range, the result torque approaches 500% of the engine rating providing large breakaway torque ideals. The mechanical drive can be able to handle a 200% overload capacity throughout the whole speed range. This efficiency advantage allows an individual to set a low speed that will help the drive package force through difficult areas.
For lower acceleration/higher torque applications, some Zero-Max drives are available with our correct angle gearbox. Some Zero-Max drives may be purchased with standard electrical motors or they may be linked to any rotating power resource up to 2000 RPM. Adjustable speed drive acceleration adjustments are easily made by shifting a lever control via an arc or turning the hand-wheel of a screw type control. In any case, easy and precise speed control configurations are possible with Zero-Max adjustable swiftness drives – also referred to interchangeably as variable speed drives.
