The gasket with the oil storage hole is arranged between the rotor shaft and the casing, grease in the oil storage hole can play a role in lubrication, friction between the gasket and the rotor shaft is reduced, and the problem that lubricating oil is extruded is not worried. Lubricating oil in the oil storage hole provides the effect of continuous lubrication, has reduced the wearing and tearing condition of gasket, and then can avoid the rotor shaft drunkenness phenomenon because of the gasket wearing and tearing bring, improves the safe in utilization and the life-span of motor. In the second mode, an oil storage hole needs to be formed in the middle of the gasket, and the structure of the gasket is complex, so that the manufacturing process and the manufacturing cost of the gasket are high.
SUMMERY OF THE UTILITY MODEL
The utility model provides a motor with wear-resisting gasket, aim at simplifies the motor structure under the prerequisite of guarantee motor durability, reduces the manufacturing cost of motor.
The purpose of the utility model can be realized by the following technical scheme:
the utility model provides a motor with wear-resisting gasket, includes the casing and is located rotor shaft in the casing, rotor shaft's one end with be provided with the gasket between the casing, the casing is equipped with one and is used for the installation the recess of gasket, gasket fixed mounting in the recess, just the gasket with one side of rotor shaft contact is the plane, rotor shaft with the one end of gasket contact is circular sphere, the gasket with the oil storage tank has been seted up on the outer fringe face of groove contact.
The utility model discloses a for the point contact between rotor shaft and the gasket, assemble the casing after rotor shaft and gasket scribble a little lubricating oil in, can reduce the wearing and tearing of rotor shaft and gasket, prevent rotor shaft drunkenness, noise reduction. The oil storage tank of gasket outer fringe face is used for the oil storage, can ensure the lubricated effect of motor during operation.
The utility model discloses still have following optimization and improve:
the utility model discloses a gasket with interference fit between the recess. During assembly, the gasket is pressed in the groove of the casing, and the oil storage groove is formed in the outer edge surface of the gasket, so that the lubricating and ventilating effects are achieved, and the gasket is convenient to press.
The quantity of oil storage tank can be for 2 ~ 6, oil storage tank evenly distributed.
The gasket of the utility model is quincunx or square, so that the gasket is matched with the groove shape of the casing.
The utility model discloses a rotor shaft with connect through the bearing between the casing, the bearing the circular sphere of rotor shaft one end with form the clearance that holds lubricating oil or lubricating grease between the gasket.
The gasket with still be equipped with the elastic rubber pad between the casing, the assembled state, the elastic rubber pad is in compression state and is used for guaranteeing motor trip distance, makes the moment of two directions of motor reach the designing requirement.
The utility model has the advantages of it is following:
1. the utility model discloses a motor simple structure, but the gasket oil storage is ventilative, scribbles a little lubricating oil or lubricating grease and just can ensure the durability of motor. The gasket has strong universality and low manufacturing cost, and can be used for the stator end and the output end of the motor.
2. The utility model discloses can reduce the wearing and tearing of electric motor rotor axle and gasket, prevent that the rotor axle drunkenness from taking place the abnormal sound, and then reduce the whole noise of motor.
