Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to a stable rotor base with ultra-wear-resistant and high-lubrication function. Background Technology

[0002] Motor rotor: This is the rotating component of an electric motor. An electric motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and vice versa. Motor rotors are divided into electric motor rotors and generator rotors.

[0003] The existing rotor housing has poor wear resistance and lubrication, and there is no lubrication function between the rotor and the rotor housing. The rotor and the rotor housing are prone to wear. At the same time, the existing rotor housing has poor heat dissipation performance. The friction between the rotor and the rotor housing generates heat, and the rotor housing cannot be cooled down. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a stable rotor seat with ultra-wear-resistant and high-lubrication function, which can lubricate the rotor and rotor seat and dissipate heat and cool the rotor seat.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable rotor seat with ultra-wear-resistant and high-lubrication function, comprising an outer rotor seat, wherein a plurality of magnetic steel grooves are provided on the inner side of the outer rotor seat, a plurality of bolt holes are provided in the outer rotor seat, an upper annular storage groove is provided on the upper side inside the outer rotor seat, a lower annular storage groove is provided on the lower side of the upper annular storage groove, a connecting channel is provided on both sides between the lower annular storage groove and the upper annular storage groove, an oil injection channel is provided on both sides of the upper end of the upper annular storage groove, a valve is fixed at the upper end of the outer rotor seat corresponding to the position of the oil injection channel, and a plurality of micro-holes are provided on the side of the upper annular storage groove and the lower annular storage groove near the magnetic steel groove.

[0006] Preferably, the outer rotor seat has several fins on its side, and the fins are connected to the outer rotor seat by several heat-conducting pillars.

[0007] Preferably, the fins have several perforations, and reinforcing rods are fixed at both ends between the fins and the outer rotor seat.

[0008] Preferably, the upper and lower annular storage tanks are staggered from the bolt holes, and the micro-holes are equidistantly distributed.

[0009] Preferably, the perforation is a tapered structure, and the reinforcing rod is fixed to the outer rotor seat and the fins by welding.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses micro-holes to allow the rotor to be installed into the outer rotor seat by fitting the magnet groove inside the outer rotor seat. Then, semi-fluid grease can be added to the oil injection channel through a valve. The semi-fluid grease enters the upper annular reservoir and then enters the lower annular reservoir through a connecting channel. Subsequently, the semi-fluid grease in the upper and lower annular reservoirs can enter between the rotor and the outer rotor seat through the micro-holes to achieve lubrication between the rotor and the outer rotor seat and reduce wear between the rotor and the outer rotor seat.

[0011] 2. This utility model uses fins to generate heat through friction between the rotor and the outer rotor seat. Several heat-conducting pillars can transfer the heat to the fins, thereby cooling the outer rotor seat and preventing it from being in a high-temperature state for a long time, which would reduce its service life. Several perforations in the fins can increase the contact range between the fins and the air, thereby increasing the cooling speed of the fins. At the same time, several reinforcing rods are set between the fins and the outer rotor seat to improve the firmness between the fins and the outer rotor seat, thus making the fins more stable.

[0015] Specifically, the outer rotor base 1 has several fins 4 on its side, and the fins 4 are connected to the outer rotor base 1 by several heat-conducting pillars 5.

[0016] By adopting the above technical solution, heat is generated by friction between the rotor and the outer rotor seat 1. Several heat-conducting columns 5 can transfer the heat to the fins 4, thereby playing a role in cooling down the outer rotor seat 1 and preventing the outer rotor seat 1 from being in a high-temperature state for a long time, which reduces its service life.

[0017] Specifically, the fin 4 has several perforations 7, and the two ends of the fin 4 and the outer rotor seat 1 are fixed with reinforcing rods 8.

[0018] By adopting the above technical solution, opening several perforations 7 in the fin 4 can increase the contact range between the fin 4 and the air, and increase the cooling rate of the fin 4. At the same time, setting several reinforcing rods 8 between the fin 4 and the outer rotor seat 1 can improve the firmness between the fin 4 and the outer rotor seat 1, thereby making the fin 4 more stable.

[0019] Specifically, the upper annular storage tank 9 and the lower annular storage tank 10 are staggered from the bolt holes 2, and the micro-holes 13 are equidistantly distributed.

[0020] By adopting the above technical solution, the upper annular storage tank 9 and the lower annular storage tank 10 are avoided from affecting the bolts passing through the bolt holes 2 for installation.

[0021] Specifically, the perforation 7 is designed as a tapered structure, and the reinforcing rod 8 is fixed to the outer rotor seat 1 and the reinforcing rod 8 to the fin 4 by welding.

[0022] By adopting the above technical solution, the perforation 7 is set as a conical structure to facilitate the passage of air through the perforation 7, and the welding fixation makes the relationship between the reinforcing rod 8 and the outer rotor seat 1, as well as between the reinforcing rod 8 and the fin 4, more secure.

[0023] The working principle and usage process of this utility model: When using the stable rotor seat with ultra-wear-resistant and high lubrication function, the device is installed in a suitable position, and the rotor is installed into the outer rotor seat 1 with the magnetic steel groove 3 inside the outer rotor seat 1. Then, semi-fluid grease is added to the oil injection channel 11 through the valve 6. The semi-fluid grease enters the upper annular reservoir 9 and enters the lower annular reservoir 10 through the connecting channel 12. Subsequently, the semi-fluid grease in the upper annular reservoir 9 and the lower annular reservoir 10 can enter between the rotor and the outer rotor seat 1 through the micro-hole 13 to achieve the lubrication effect between the rotor and the outer rotor seat 1 and reduce the wear between the rotor and the outer rotor seat 1.

[0024] Heat is generated by friction between the rotor and the outer rotor seat 1. Several heat-conducting pillars 5 can transfer the heat to the fins 4, thereby cooling the outer rotor seat 1 and preventing it from being in a high-temperature state for a long time, which would reduce its service life. Several perforations 7 are opened in the fins 4 to increase the contact range between the fins 4 and the air, thereby increasing the cooling speed of the fins 4. At the same time, several reinforcing rods 8 are set between the fins 4 and the outer rotor seat 1 to improve the firmness between the fins 4 and the outer rotor seat 1, thus making the fins 4 more stable.
