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

Rate reducers are mechanical products generally used for just two purposes. The primary use is usually to multiply the quantity of torque generated by an input power source to boost the amount of usable work. In addition they reduce the input power supply speed to achieve desired output speeds.

Gearboxes are accustomed to increase torque while reducing the quickness of a prime mover output shaft (a engine crankshaft, for example). The result shaft of a gearbox rotates at a slower price compared to the input shaft, which reduction in quickness produces a mechanical benefit, increasing torque. A gearbox could be set up to do the opposite and offer an increase in shaft swiftness with a reduced amount of torque.

Enclosed-drive speed reducers, also called gear drives and gearboxes, have two primary configurations: in-line and right angle which use different types of gearing. In-line versions are commonly produced up of helical or spur gears, planetary gears, cycloidal mechanisms, or harmonic wave generators. Right angle designs are usually made out of worm gearing or bevel gearing, though hybrid drives are also offered. The type of program dictates which velocity reducer design will best satisfy the requirements.
D- Drive is a variable acceleration geared motor, robust stage less unit suitable for various industrial applications.The machine is designed to provide low output speed at corresponding high output torque. The drive unit is manufactured from standard parts and consists of AC squirrel cage engine, variable quickness drive and gearbox with case hardened profile ground helical gears. It could be quickly adapted to any machine design. The unit is quite compact and save time and money because they are ready to suit drive modules. The inside part of this drive may be the variable speed pulley enclosed in a housing and linked to the gearbox and electric motor. The speed variation may be Variable Speed Gearbox accomplished through a hand wheel. Typical life to be expected is about a decade before major maintenance. Belt life is based on software and environment. General encounter is about 3 to 4 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 includes an insight disc, a couple of planetary cones, a control band, the cam disc and a pressure control cam. The Ring-cone has different sizes to handle engine power ranging between 1/4HP – 20HP, and nominal result torque rankings spanning 15 – 130,000 in-lbs. This original drive provides a speed range of 0 – 800 RPM, and a cam system that adjusts to the surroundings downstream and may withstand a certain quantity of shock load.

With a variable frequency drive, the output torque continues to be constant from base speed right down to the low limit, whatever it could be for the application. However, with the Ring-cone mechanical variable speed drive the output torque improves as the rate drops. At the low speed range, the output torque methods 500% of the electric motor rating providing huge breakaway torque values. The mechanical drive is also able to handle a 200% overload capability throughout the whole speed range. This overall performance advantage allows an individual to set a minimal speed that can help the drive package press 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 electric motors or they may be linked to any rotating power supply up to 2000 RPM. Adjustable speed drive quickness adjustments are easily created by shifting a lever control via an arc or turning the hand-wheel of a screw type control. In either case, easy and precise speed control settings are possible with Zero-Max adjustable acceleration drives – also described interchangeably as variable swiftness drives.
