AI Technical Summary
Technical Problem
In the rotor assembly of the existing frequency converter motor, the connection hole diameter of the core pulling rivet is difficult to control, which causes the core pulling rivet to break during high-speed operation, which in turn causes the oil stop plate to fall off and reduces the operating reliability of the frequency converter motor.
Method used
An oil barrier balance piece is designed to connect the oil barrier plate and the balance block into one through snaps, and then rivet with the rotor core as a whole to avoid using core pull rivets.
Benefits of technology
This design improves the operating reliability of the motor, avoids the problem of oil barrier plate falling off due to fracture of the core rivet, and enhances the stability of the motor.

Abstract
The invention provides an oil baffle balance part, a motor rotor and a compressor. The oil baffle balance part comprises an oil baffle plate and a balance block, the oil baffle plate comprises an oil baffle plate body and a buckle connected to the outer edge of the oil baffle plate body, the buckle comprises a joint part and a flange, the joint part is connected with the oil baffle plate body and extends in the axial direction of the oil baffle plate body, and the flange is connected with the joint part and extends inwards in the radial direction of the oil baffle plate body; a clamping groove is formed between the buckle and the oil baffle plate body and contains a part of the balance block, and the oil baffle plate body, the joint part and the flange all abut against the balance block. The oil baffle balance piece is applied to the motor rotor and arranged at the end of the rotor iron core, when the oil baffle balance piece is connected with the rotor iron core, the oil baffle plate is connected with the balance block through the buckle, and then the oil baffle balance piece is connected with the rotor iron core, so that the oil baffle plate and the balance block do not need to be connected through a self-plugging rivet; therefore, the problem that the self-plugging rivet is broken in the operation process of the motor due to the fact that the tolerance of the hole provided with the self-plugging rivet is too large is solved, and the operation reliability of the motor with the oil baffle balance part is improved.
