Embodiment 1

[0047] This embodiment provides a bearing chamber, such as Figure 4 As shown, the bearing chamber 4 is cylindrical, the inside of which is a cavity, and the end face has an opening, and the diameter of the opening is smaller than the inner diameter of the cavity. When in use, the bearing 3 is installed in the bearing chamber. cannot come out of the opening.

[0048] Such as Figure 4 As shown, the inner wall surface of the bearing chamber 4 is provided with a recess 5, such as Figure 5 , 6 As shown, the concave portion 5 is provided with an elastic body 6 , and the elastic body 6 radially protrudes from the inner wall surface of the bearing chamber 4 .

[0049]The above-mentioned bearing chamber 4 has a concave portion 5 on its inner wall surface, and the elastic body 6 is placed in the concave portion 5, and the elastic body 6 protrudes from the inner wall surface. Since the recess 5 is provided on the inner surface of the bearing chamber, the bearing chamber 4 and the ...

Embodiment 2

[0058] This embodiment provides a motor casing, such as Figure 7 As shown, the motor casing 1 is formed by butting the first casing 11 and the second casing 12, and the butt surface of the first casing 11 and the second casing 12 extends along the vertical direction, and also That is, the first casing 11 and the second casing 12 are arranged along the left-right direction, so as to form a joint surface in the vertical direction.

[0059] Here, it should be noted that the abutting surfaces of the first casing 11 and the second casing 12 extend along the vertical direction, which does not mean that the abutting surfaces of the two are completely vertical, but only that the first casing 11 and the second cabinet 12 are arranged along the left-right direction in the horizontal direction.

[0060] Such as Figure 7 As shown, the first casing 11 has a flange at the abutting surface, and the second casing 12 has a groove at the abutting surface, and the flange fits exactly with th...

Embodiment 3

[0065] This embodiment provides a motor, including a motor casing 1, a bearing 3 installed in the bearing chamber 4 of the motor casing 1, and a rotating shaft 2, and the rotating shaft 2 extends into the bearing chamber 4 and is connected with the bearing chamber 4. The bearing 3 is matched, and the bearing chamber 4 is any one of the bearing chambers described in Embodiment 1.

[0066] Such as Figure 7 , 8 As shown, the inner wall surface of the above-mentioned bearing chamber 4 is provided with a concave portion 5, and the elastic body 6 is placed in the concave portion 5, and the elastic body 6 protrudes from the inner wall surface. Since the recess 5 is provided on the surface of the inner wall of the bearing chamber, the bearing chamber 4 and the bearing 3 can be designed according to the clearance fit size of the base hole system, so that when the bearing 3 is installed into the bearing chamber 4, it is not necessary to heat the bearing chamber 4, and the bearing can ...

Abstract

The invention discloses a bearing chamber, a motor enclosure having the same and a motor. A recess is formed on an inner wall surface of the bearing chamber, an elastomer is placed in the recess, and the elastomer protrudes out of the inner wall surface. As the inner wall surface of the bearing chamber is provided with the recess, the bearing chamber and a bearing can be designed with a clearance fit dimension according to a basic hole system, and when the bearing is to be installed in the bearing chamber, the bearing can be directly pressed into the bearing chamber without heating the bearing chamber. The installation way is convenient, the assembly technique is simple and the production efficiency is high. As the elastomer is made of a material easy to compress and the elastomer arranged in the recess radially protrudes out of the inner wall surface of the bearing chamber, even if the bearing chamber and the bearing are designed with a clearance fit dimension according to the basic hole system, after the bearing is installed in the bearing chamber, the bearing squeezes the elastomer and the bearing forms interference fit with the bearing chamber arranged at the elastomer, thus achieving the effect of preventing wriggle of the bearing.

Description

technical field [0001] The invention relates to the field of motors, in particular to a bearing chamber, a motor casing with the same and a motor. Background technique [0002] The bearing chamber of the existing motor is usually a cylindrical structure, such as figure 1 shown. The fit between the inner wall surface of the bearing and the bearing is usually mainly in two ways: clearance fit and interference fit. Because the current motor is to enhance heat dissipation, its casing is mostly made of aluminum casing, which is prone to deformation during use, resulting in technical defects no matter what kind of bearing chamber and bearing matching method is used. Specifically: [0003] figure 2 Shown is a structural schematic diagram of the prior art bearing chamber and bearing clearance fit. Due to the existence of the gap 1', the assembly process of the bearing is simple and fast; however, due to the existence of the above-mentioned gap 1' and the low strength of the al...
