Description

Technical Field

[0001] The utility model relates to the technical field of remanufacturing starters, in particular to a starter rotor grinding device. Background Art

[0002] The starter rotor is the rotating part of the motor. The rotor and stator are important components of the starter. They are devices used to realize the mutual conversion between electrical energy and mechanical energy or mechanical energy and electrical energy. The fixed part of the starter is called the stator, on which a pair of static main magnetic poles with DC excitation are installed. Among them, the stator winding can be divided into centralized and distributed types according to the shape and embedding method of the coil winding. The rotating part is the rotor. The main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate (output) current, thereby obtaining a torque. The rotor consists of a rotor core, a rotor winding, a commutator and a rotor shaft. The function of the rotor winding is to induce electromotive force and generate electromagnetic torque through current. The rotor shaft supports the weight of the rotor, transmits torque, and outputs mechanical power. The interaction between the rotor and the stator is the basis for the operation of the motor. The rotor rotates in the rotating magnetic field generated by the stator, thereby generating electromagnetic torque, driving the load to rotate for energy conversion, and transmitting the torque of the motor to the crankshaft of the diesel engine. The motor rotor is divided into two types: inner rotor rotation mode and outer rotor rotation mode. The inner rotor rotation mode is that the core in the middle of the motor is the rotating body, outputting torque or receiving energy. The outer rotor rotation mode is that the outer body of the motor is the rotating body. Different modes facilitate the application of various occasions.

At present, the grinding operation of the rotor shaft and commutator of the starter rotor is mostly carried out separately. This operation method cannot control the uniformity of the grinding of the rotor shaft and commutator, has low operation accuracy, and is prone to reprocessing due to uneven grinding problems, affecting the efficiency of the starter rotor processing operation.
