Description

Technical Field

[0002] Roller equipment is currently widely used in various forms of logistics sorting equipment. Most rollers use a power mechanism that combines an electric motor with a reducer. The electric motor is used as the original power, and the reducer drives the roller body to rotate after deceleration. However, in actual use, due to the characteristics of its driving principle, the electrically driven roller will be limited in many usage scenarios. For example, in the use scenarios of engineering dust collection belt conveyors, conveyor belt conveyors, etc., which are directly powered by internal combustion engines, there will be a lot of energy loss in the process of converting mechanical energy into electrical energy and then back into mechanical energy. The more complex circuit control system is also difficult to cope with harsh and complex operating conditions such as high temperature and wading. Therefore, for the above-mentioned usage scenarios, most rollers will use hydraulic motors as the power source to form a hydraulically driven roller.
