Problems solved by technology

[0004] When the rotating shaft rotates, it directly rubs against the motor casing, which is likely to cause noise. By setting the vibration guide plate, vibration offset plate and shock-absorbing rubber sleeve, the effect of noise reduction can be achieved through shock absorption, but the noise generated by rotational friction cannot be solved.

Embodiment 1

[0033] Embodiment one: if figure 1 and figure 2 As shown, a motor housing includes a housing body 1, and the housing body 1 is generally made of stamping and deep drawing. A stator, a rotor, a shaft and a bearing are installed in the housing body 1, and the stator is fixed on the housing On the side wall of the body 1 , the shaft passes through both ends of the housing body 1 . One end of the housing body 1 is an opening 11, and the opening 11 is used for fixing the end cover. The side wall of the housing body 1 is symmetrically provided with square slots 12, and the slots 12 are arranged at the opening 11. The slots 12 are convenient for quick positioning of the end cover and prevent the end cover from rotating. The inner diameter of the side wall of the housing body 1 at the slot 12 is reduced to form a step 13, which is used for interference fit with the fixed end of the end cover, so as to realize the fixation.

Embodiment 2

[0040] Embodiment two: if Figure 4 and Figure 5 As shown, the difference from Embodiment 1 is that, on the outside of the side wall of the motor casing body 1, the punch is squeezed into the side wall, forcing the outer wall of the casing body 1 to form several grooves 2, and the casing The inner wall of the body body 1 forms corresponding ribs, the groove 2 is a strip groove arranged in the axial direction, and the length of the groove 2 is smaller than the length of the side wall of the housing body 1, and the two adjacent grooves 2 are in the horizontal direction. If they are set at a certain interval, there is a slideway 21 between two adjacent raised ribs. A sound-absorbing block 3 is arranged in each groove 2, and the sound-absorbing block 3 is made of rubber, elastic plastic, polyester fiber or soft foam plastic, and the size of the sound-absorbing block 3 is slightly larger than the groove 2, so that the sound-absorbing block 3 Interference fit with the groove 2, t...

Abstract

The invention discloses a motor shell, for solving the noise problem caused by friction between a rotating shaft in the motor and the motor shell during rotation of the rotating shaft in the motor. The motor shell is mainly characterized by comprising a shell body, the two end faces of the shell body are respectively provided with a shaft hole for the shaft to penetrate and an opening used for fixing an end cover, a fixing part with a shaft hole is formed in one end face of the shell body in a stamping and drawing mode, a plurality of oil injection holes are formed at a position, close to theend face of the shell body, of the side wall of the fixing part, and each of the oil injection holes is provided with a sealing plug used for blocking the oil injection hole. The oil injection holes are facilitated, convenience is brought for adding lubricating oil to a fixed position of the rotating shaft, friction is reduced, and therefore noise is reduced.

Description

technical field [0001] The invention relates to the field of motor accessories, more specifically, to a motor housing. Background technique [0002] The pace of social and economic development is accelerating, and all walks of life are changing with each passing day. All kinds of electrical equipment have been developed and applied to various occasions. Among them, the motor has become the key equipment and has been widely used in many occasions. Motor (commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. The existing motor mainly has the disadvantage of unstable operation, and the problem of high noise is likely to occur during operation. [0003] The invention with the application number CN201420396489.4 discloses a low-noise heat-dis...
