Description

Motor oil-throwing-preventing structure and motor

Technical Field

The utility model relates to a motor especially relates to a motor prevents getting rid of oily structure.

Background

The existing motor rotating shaft generates friction with a cup when rotating, the friction can generate noise, the noise is very high when the motor runs, and the two parts can be abraded even if the motor is serious, so that the motor is damaged. Therefore, it is generally necessary to add lubricating oil between the cup and the rotating shaft to ensure lubrication between the cup and the rotating shaft, so as to ensure stable operation of the motor. However, because of the clearance between the rotating shaft and each part, the lubricating oil is thrown out by the centrifugal force when the rotating shaft rotates, so that the lubricating oil between the cup and the rotating shaft is less and less. After long-time use, lack of lubricating oil between cup and the pivot can produce great noise and take place wearing and tearing gradually again, and then shorten the life of motor. So far, there is no effective method for preventing the lubricating oil from being thrown out.

Preferably, the outer side of the gland is provided with a shaft sleeve.

Preferably, a second graphite ring is arranged between the shaft sleeve and the gland.

Preferably, a felt ring is arranged between the gland and the oil baffle ring.

Preferably, the bowl mouth of the oil baffle ring is gradually enlarged from inside to outside.

Preferably, the joint of the support and the gland is provided with sealing silica gel.

The utility model provides a motor, includes stator winding, rotor, pivot and motor and prevents getting rid of oily structure, the rotor is fixed in the pivot, the pivot set up in one side of stator winding, the motor prevent getting rid of oily structure set up in the pivot and be located the both sides of rotor.

Detailed Description

In order to explain technical contents, structural features, and effects achieved by the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

As shown in fig. 1 and fig. 2, the motor 100 of the present invention includes a stator winding 1, a rotor 2, a rotating shaft 3 and a motor anti-throwing oil structure 4, the rotor 2 is fixed on the rotating shaft 3, the rotating shaft 3 is arranged on one side of the stator winding 1, the motor anti-throwing oil structure 4 is arranged on the rotating shaft 3 and is located on two sides of the rotor 2. The motor oil-throwing prevention structure 4 comprises a support 41, a cup 42, an oil baffle ring 43 and a gland 44 which are sequentially sleeved on the rotating shaft 3 of the motor 100, wherein the support 41 and the gland 44 are combined to form an accommodating cavity 4a for accommodating the cup 42; the joint of the support 41 and the gland 44 is provided with a sealing layer, and the sealing layer is sealing silica gel 4 b. The oil baffle ring 43 is located in the accommodating cavity 4a and is of a bowl-shaped structure, and the bowl opening 43a of the oil baffle ring 43 is gradually enlarged from inside to outside. The bowl mouth 43a of the oil deflector 43 faces the cup 42 to collect the oil flowing from the cup 42 and throw it back to the cup 42.

An oil felt ring 45 is arranged in the accommodating cavity 4a, and the oil felt ring 45 is sleeved outside the cup 42.

The accommodating cavity 4a is internally provided with an elastic sheet 46 which is sleeved outside the cupola 42 and positioned at one side close to the gland 44 so as to clamp the felt ring 45 with the inner side of the bracket 41. The elastic piece 46 is circumferentially provided with a through hole for passing through the lubricating oil thrown back from the oil baffle ring 43 to the cup 42.

A plurality of first graphite rings 47 are axially arranged between the cupola 42 and the oil baffle ring 43.

The outside of the gland 44 is provided with a bushing 48.

A second graphite ring 49 is arranged between the shaft sleeve 48 and the gland 44.

A felt ring 50 is arranged between the gland 44 and the oil deflector 43.
