Sany And Zoomlion Concrete Pump Coupling spline sleeve inner 28 teeth

The coupling spline sleeve between the diesel engine and oil pump in a concrete line pump serves an important function in the operation of the equipment. Here is a description of the function and role of the coupling spline sleeve:

1. Power Transmission: The coupling spline sleeve acts as a connection between the diesel engine and the oil pump, facilitating the transfer of power from the engine to the pump. It allows for the rotational motion of the engine to be transmitted to the oil pump, which drives the pumping mechanism in the concrete line pump.

2. Misalignment Compensation: The coupling spline sleeve is designed to accommodate slight misalignments between the diesel engine and the oil pump. It can compensate for minor axial, radial, and angular misalignments that may occur due to vibrations, thermal expansion, or other factors. This helps to ensure a smooth and efficient power transmission between the engine and the pump.

3. Shock Absorption: The coupling spline sleeve also provides a degree of shock absorption between the diesel engine and the oil pump. It helps to dampen any sudden or excessive vibrations or shocks that may be generated during operation. By absorbing and reducing these vibrations, the coupling spline sleeve helps to protect the components of the concrete line pump and prolong their lifespan.

4. Torque Limitation: In some cases, the coupling spline sleeve may incorporate a torque limitation mechanism. This mechanism is designed to protect the diesel engine and oil pump from excessive torque or overloading. It can help prevent damage to the components and ensure the safe operation of the equipment.

Overall, the coupling spline sleeve between the diesel engine and oil pump in a concrete line pump plays a critical role in transmitting power, compensating for misalignments, absorbing shocks, and providing torque limitation. It ensures the smooth and efficient operation of the equipment, protects the components from damage, and contributes to the longevity and reliability of the concrete line pump.
