Description

Technical Field

[0001] The utility model relates to the technical field of motor rotors, in particular to a motor rotor with a lubrication component. Background Technique

[0002] The motor rotor is a rotating component in a motor. The motor consists of two parts, the rotor and the stator. It is a device for realizing the conversion between electrical energy and mechanical energy and between mechanical energy and electrical energy. The motor rotor is divided into a motor rotor and a generator rotor. The motor rotor is divided into two rotation modes: the inner rotor rotation mode and the outer rotor rotation mode. In the inner rotor rotation mode, the core in the middle of the motor is the rotating body, outputting torque (for a motor) or receiving energy (for a generator). In the outer rotor rotation mode, the outer body of the motor is the rotating body. Different modes facilitate the application in various occasions;

The discharge nozzles are connected to the through groove on the inner wall of the housing. An inlet is arranged at the top of the through groove located above. Lubricating oil can be dripped into the through groove through the inlet. The lubricating oil flows along the through groove to the discharge nozzles. Since the discharge nozzles are directly opposite to the discharge holes on the bearing, the lubricating oil is dripped into the discharge holes by the discharge nozzles, thereby playing a lubricating role. And an air duct is connected in the through groove located below. The air duct is connected to the fan. The fan blows air to the discharge holes on the rotating shaft from the discharge nozzles below, making the heat dissipation effect at the connection between the rotor and the rotating shaft better.
