The excavator rotary motor is a key component of the excavator’s rotary mechanism. It converts the oil pressure provided by the main pump into mechanical energy, which is then input into the reducer. This directly affects the excavator’s rotation speed, driving torque, rotation stop, and parking brake, making it a critical factor in determining the overall machine productivity.
The performance of the excavator rotary motor directly impacts the overall performance of the excavator. By converting hydraulic energy into mechanical energy, the rotary motor enables the excavator to perform left and right rotation actions. This process involves the coordinated work of multiple components and systems, including the rotary hydraulic system, control valves, etc., to ensure the stability and efficiency of the excavator during operation.
Specifically, the rotary motor operates through an axial piston hydraulic motor, using the reaction force generated by high-pressure hydraulic oil to produce torque, which is then transmitted to the drive shaft. After being reduced by the rotary reducer, the output power acts on the rotary support, allowing the upper structure of the excavator to smoothly complete the rotation motion. Additionally, the excavator rotary motor is equipped with safety and control components such as a rotary overflow valve, delay valve (brake valve), replenishing valve, etc., to ensure safe machine operation and operator comfort.
