Drives and transmissions can be defined as a group of mechanical devices which work hand in hand to generate and control a mechanical movement which is completed by the help of wheels. They function by powering a machine or motor from one place to another after the moving process has been initiated by another source of power be it electric or mechanical.
Transmissions can be defined as an assembly of mechanical parts which include gears and a propeller shaft which are powered via an engine straight to the axle.
In any mechanical industry, these devices are of great help since they simplify movement and reduce the normal workload. The high rotational speed that is associated with any type of motor is controlled at a more desirable pace thank to the drives and transmissions. They carry out this function by reducing the high engine speed to a much slower wheel speed hence increasing torque in the process.
In most cases, transmissions come equipped with multiple gears which have the ability to switch between themselves as speed varies. Examples of such transmissions include; gear reducers, spur gear reducers, bevel gear reducers and right angle gear reducers. All of these gear reducers are primarily located in the gearbox of any moving motor.
Most industrial machines have their transmissions directly connected (linear) to the engine crankshaft via a clutch or a flywheel. The output power transmission of the engine is usually transmitted via a driveshaft to a number of differentials which in turn powers the wheels. During this process, motorized linear guides and actuators play a very significant role.
The switching between transmissions, gears and drives can either be done manually (by the operator) or automatically (by the motor). Manually controlled devices are common in manual motor gearboxes where the operator has to switch between gears to reach the required speeds. In automatic transmissions the change between gears is done automatically by the motor gearboxes. Another form of gear movement is the directional movement which allows both forward and backward movement as well as the single ratio transmissions which function by changing the speed and torque of the motor output.
Majority of industrial motors are nowadays powered electrically. This form of power has significantly reduced workload and made electric powered motors highly dependable. Electrically powered motors fall under the category of DC electric servo-motors, electric-servo motors, AC motors and DC motors. Each and every motor has its own specifications depending on the tasks subjected to it.
Bearings also play a very important role in the movement of any industrial motor. They function by reducing friction between the moving parts as well as constrain relative motion. The tearing and wearing of industrial moving parts is highly reduced and controlled by these bearings. Since they move in a circular motion, a constant relative movement is achieved which in turn reduces workload and keeps the machine in check. Worn-out bearings highly reduce or prevent any form of movement. Sophisticated bearings which are used in the current industry require the best technology to produce them so as to maintain precise movements. Different bearings come with different speeds and hence different bearings are used in different applications where different speeds are required to run different applications.Read less
