Model Numbers: 283 - 5992, 296 - 5159/2965159
Applicable Equipment: cat330c, E330C, E330CL, CS - 533E, CS - 54 Excavators
Function: The piston motor and associated hydraulic gear play a crucial role in the excavator's hydraulic system. The piston motor converts hydraulic energy into mechanical rotational energy, which is then used to drive various components such as the excavator's tracks, swing mechanism, or other working parts through the hydraulic gear.
2. Performance Specifications
2.1 Torque Output
Rated Torque: The piston motor is designed to provide a rated torque of [X] Nm (Newton - meters). This torque value is essential for effectively driving the hydraulic gear and the connected components, allowing for smooth and powerful operation of the excavator's movements.
Peak Torque: The motor can generate a peak torque of [Y] Nm for short - term, high - load situations such as when the excavator encounters sudden resistance during operation. The peak torque capacity ensures that the motor and gear can handle unexpected loads without stalling or suffering damage.
2.2 Speed Ratings
Rated Speed: The rated rotational speed of the piston motor is [N1] revolutions per minute (rpm). This speed is optimized to work in conjunction with the hydraulic gear to provide the appropriate speed for the excavator's normal operation. It affects the productivity and efficiency of the excavator's movements.
Speed Range: The motor may have a variable speed range. The minimum speed can be [N2] rpm and the maximum speed up to [N3] rpm. This range allows for adjustment of the speed according to the specific requirements of the work, such as slow and precise movements for delicate operations or high - speed rotations for rapid repositioning.
3. Construction and Components
3.1 Motor Type
Piston Motor: The 296 - 5159/2965159 is a piston - type motor. Piston motors are known for their high - efficiency and ability to handle relatively high pressures. The pistons move in a reciprocating motion within the cylinders to convert hydraulic pressure into rotational motion. The construction of the pistons, including their material (usually hardened steel) and precise machining, is crucial for minimizing internal leakage and maximizing torque output.
Cylinder Block: The cylinder block is a vital component made of high - strength materials such as alloy steel. It provides a precise housing for the pistons and is machined to tight tolerances to ensure accurate piston movement and proper sealing. The quality of the cylinder block affects the overall performance and durability of the motor.
Hydraulic Gear: The hydraulic gear (283 - 5992) is designed to transfer the rotational power from the piston motor to the desired components. It consists of a set of gears made of high - quality alloy steel. The gear teeth are carefully machined to ensure smooth and efficient power transmission. The gear ratio is selected to match the torque and speed requirements of the excavator's functions.
Output Shaft: The output shaft of the motor is designed to connect to the hydraulic gear. It is made of a strong material to withstand the torque and rotational forces. The shaft's dimensions and connection methods (such as keyways or splines) are designed to ensure a reliable and efficient transfer of power to the gear.
