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

Acceleration reducers are mechanical products generally used for two purposes. The primary use is certainly to multiply the amount of torque generated by an input power source to boost the quantity of usable work. They also decrease the input power resource speed to achieve desired output speeds.

Gearboxes are used to increase torque whilst reducing the rate of a prime mover result shaft (a engine crankshaft, for example). The output shaft of a gearbox rotates at a slower rate than the input shaft, and this reduction in swiftness produces a mechanical benefit, raising torque. A gearbox could be set up to accomplish the opposite and offer an increase in shaft velocity with a reduction of torque.

Enclosed-drive speed reducers, also known as gear drives and gearboxes, have two main configurations: in-line and right angle which use various kinds of gearing. In-line versions are commonly produced up of helical or spur gears, planetary gears, cycloidal mechanisms, or harmonic wave generators. Correct angle designs are typically made with worm gearing or bevel gearing, though hybrid drives are also available. The type of program Variable Speed Gearbox dictates which acceleration reducer style will best fulfill the requirements.
D- Drive is a adjustable rate geared motor, robust step less unit suitable for different industrial applications.The unit is designed to provide low output speed at corresponding high output torque. The drive unit is produced from standard parts and comprises of AC squirrel cage electric motor, variable rate drive and gearbox with case hardened profile ground helical gears. It could be quickly adapted to any machine design. The machine is quite compact and save money and time because they are prepared to suit drive modules. The inside part of the drive is the variable speed pulley enclosed in a casing and connected to the gearbox and motor. The speed variation may be accomplished by means of a hand wheel. Typical life to be expected is about 10 years before main maintenance. Belt life is based on program and environment. General experience is about three to four 4 years life.
The Ring-cone is a mechanical adjustable speed drive employing a ring and cone friction power train – hence the name. The inner drive assembly consists of an input disc, a set of planetary cones, a control ring, the cam disc and a pressure control cam. The Ring-cone offers different sizes to take care of motor power ranging between 1/4HP – 20HP, and nominal output torque ratings spanning 15 – 130,000 in-lbs. This original drive provides a speed selection of 0 – 800 RPM, and a cam mechanism that adjusts to the surroundings downstream and can withstand a certain amount of shock load.

With a variable frequency drive, the output torque continues to be constant from base speed down to the lower limit, whatever it might be for the application. However, with the Ring-cone mechanical adjustable speed drive the output torque raises as the acceleration 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 capable of handling a 200% overload capacity throughout the whole speed range. This efficiency advantage allows the user to set a low speed which will help the drive package force through difficult areas.
For lower swiftness/higher torque applications, some Zero-Max drives are available with our right angle gearbox. Some Zero-Max drives may be purchased with standard electric motors or they may be connected to any rotating power source up to 2000 RPM. Adjustable speed drive acceleration adjustments are easily made by moving a lever control through an arc or turning the hand-wheel of a screw type control. In either case, easy and precise speed control settings are feasible with Zero-Max adjustable velocity drives – also described interchangeably as variable swiftness drives.
