the driving form of the excavating speed reducer adopts a small-displacement hydraulic motor to drive a single-input-port excavating speed reducer, the structure of the small-displacement hydraulic motor is simple, the price of the small-displacement motor is low, but in order to meet the high-power requirement of driving the excavating speed reducer, the maximum working pressure set value of the motor is basically close to the maximum pressure limit of the hydraulic motor, the pressure safety margin reservation is insufficient, and when the small-displacement hydraulic motor is used under the working condition of excavating high-impact force load, the hydraulic motor is easily damaged when the hydraulic motor is used under overpressure;
the second type adopts a large-displacement hydraulic motor to drive a single-input-port excavating speed reducer, the excavating speed reducer in the driving mode has a simple structure, and the pressure and rotating speed safety margins of the hydraulic motor are slightly increased, but the large-displacement hydraulic motor has large rotor mass and lower limit rotating speed, so that the pressure and rotating speed safety margins of the hydraulic motor are limited to be increased, the large-displacement hydraulic motor is expensive, and the whole economic efficiency of the scheme is insufficient;
and the third method adopts a double-digging motor to drive a double-input-port digging speed reducer. Although the driving form adopts a double-motor driving form, the selection of the excavator motor can reserve larger pressure and rotation speed safety margin. However, the driving type excavating speed reducer needs to be provided with two input ports for installing two hydraulic motors, so that the driving type excavating speed reducer is complex in structure and insufficient in overall economy of the scheme.
