Understanding Variable Speed Gearboxes and their Role in Automation Control Systems

Variable speed gearboxes and speed reducers are integral components in automation control systems. These mechanical devices have a significant role in enhancing the output of work while controlling the speed of the input power source.

Variable Speed Gearboxes and Speed Reducers: The Basics

Speed reducers are widely used in two primary areas. Their main function is to amplify the torque generated by an input power source, thereby increasing the volume of work that can be performed. They also serve to reduce the speed of the input power source to achieve the desired output speeds.

Gearboxes, on the other hand, are designed to enhance torque while reducing the speed of a prime mover output shaft, such as a motor crankshaft. The output shaft of a gearbox spins at a slower pace than the input shaft, and this drop in speed results in a mechanical advantage, which increases torque. Interestingly, a gearbox can also be configured to perform the opposite task, providing an increase in shaft speed with a reduction in torque.

Types of Speed Reducers and Gearboxes

Enclosed-drive speed reducers, also known as gear drives and gearboxes, come in two primary configurations: in-line and right angle. Each uses different types of gearing.

In-line models usually comprise helical or spur gears, planetary gears, cycloidal mechanisms, or harmonic wave generators. Right angle variable speed gearbox designs typically incorporate worm gearing or bevel gearing, though hybrid drives are also available. The type of application dictates which speed reducer design is best suited to meet the requirements.

The D-Drive Variable Speed Gearbox

The D-Drive is a variable speed gear motor, a robust stepless unit suitable for various industrial applications. This device is designed to provide low output speed with corresponding high output torque. The D-Drive is composed of standard components and includes an AC squirrel cage motor, variable speed drive, and a gearbox with case-hardened profile surface helical gears. The unit is compact and saves time and money as it's ready to fit drive modules.

The Ring-Cone Variable Speed Drive

The Ring-Cone is a mechanical variable speed drive that uses a ring and cone friction power train. This unique drive provides a speed range of 0 – 800 RPM, and a cam mechanism that adjusts to the environment downstream and can withstand a certain amount of shock load.

Zero-Max Drives for High Torque Applications

For applications that require lower speed and higher torque, some Zero-Max drives are available with a right angle gearbox. These drives can be purchased with standard or can be connected to any rotating power source up to 2000 RPM. Speed adjustments are easily made by moving a lever control through an arc or turning the hand-wheel of a screw type control. In any case, effortless and precise speed control settings are achievable with Zero-Max variable speed drives.
