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

Velocity reducers are mechanical devices generally used for just two purposes. The primary use is certainly to multiply the amount of torque produced by an insight power source to boost the quantity of usable work. They also reduce the input power supply speed to accomplish desired output speeds.

Gearboxes are accustomed to increase torque while reducing the rate of a primary mover output shaft (a electric motor crankshaft, for example). The result shaft of a Variable Speed Gearbox gearbox rotates at a slower price compared to the input shaft, which reduction in acceleration produces a mechanical benefit, raising torque. A gearbox can be set up to accomplish the opposite and provide 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 models are commonly produced up of helical or spur gears, planetary gears, cycloidal mechanisms, or harmonic wave generators. Correct angle designs are typically made out of worm gearing or bevel gearing, though hybrid drives are also available. The type of app dictates which speed reducer style will best satisfy the requirements.
D- Drive is a variable speed geared motor, robust stage less unit suitable for different industrial applications.The unit is made to provide low output speed at corresponding high output torque. The drive device is produced from standard elements and comprises of AC squirrel cage engine, variable swiftness drive and gearbox with case hardened profile floor helical gears. It could be easily adapted to any machine design. The machine is quite compact and save time and money because they are prepared to suit drive modules. The inside part of the drive is the variable acceleration pulley enclosed in a casing and linked to the gearbox and engine. The speed variation can be achieved by means of a hand wheel. Average life to be likely is about 10 years before major maintenance. Belt life would depend on program 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 internal drive assembly contains 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 take care of electric motor power ranging between 1/4HP – 20HP, and nominal result torque ratings 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 can withstand a certain quantity of shock load.

With a variable frequency drive, the output torque continues to be continuous from base speed right down to the low limit, whatever it could be for the application. However, with the Ring-cone mechanical adjustable speed drive the output torque increases as the speed drops. At the reduced speed range, the output torque approaches 500% of the electric motor rating providing large breakaway torque values. The mechanical drive is also able to handle a 200% overload capability throughout the entire speed range. This performance advantage allows the user to set a minimal speed which will help the drive package press through difficult areas.
For lower quickness/higher torque applications, some Zero-Max drives can be found with our correct angle gearbox. Some Zero-Max drives may be purchased with standard electrical motors or they might be connected to any rotating power source up to 2000 RPM. Adjustable speed drive acceleration adjustments are easily made by moving a lever control via an arc or turning the hand-wheel of a screw type control. In any case, easy and specific speed control configurations are possible with Zero-Max adjustable rate drives – also described interchangeably as variable swiftness drives.
