What is a drum engine?

The drum engine, also referred to as a motorized pulley, is a highly efficient motor drive that has been closed with a metal shell. They are usually seen in the transport strips of all kinds, including airport X -ray machines, cash register terminals in a supermarket and transport belts. In all these cases, multiple drum engines are installed under the surface of the belts, helping to pull the belts. These engines operate by transmission of torque from the engine through the gearbox and to the drum shell. This causes the device to turn and create the desired movement. Dust usually cannot penetrate the drum engine, or chemicals or high -pressure flows of water, causing them to adapt to a large scale of potentially hazardous conditions. They can operate at temperatures from -40 ° F (-40 ° C) to more than 122 ° F (50 ° C), which makes them suitable for large number of different climate. In addition, they can be installed either horizontally or vertically without compromising their functionally, which further increases their utilizationMine.

The external shell of the drum drum is usually designed from steel, aluminum or stainless steel. In addition, the case itself is usually crowned to create smooth monitoring of the central belt in the gear. This means that the case is slightly recorded as a crown sitting on its side, which provides more consistent operation of the device.

During the operation of any mechanical or electrical equipment, some generated energies will be lost on friction and other cannibalist forces, as the original signal passes through the driving train. This energy loss is quite natural, it occurs in all types of engines. Drum engines use helical or planetary transfers - toothed structures that provide friction loss - allowing them to work in many cases with an efficiency of approximately 95%. Only about 5% of the engine output cannot actually power the engine connected to the engine.
