Problems solved by technology

This structure has the following disadvantages: the positioning accuracy is restricted by the riveting accuracy between the front end cover A2 of the casing and the gland A5 and the machining accuracy of the two parts, and the riveting accuracy of the two is restricted by the technical level of the operator, and the accuracy is difficult to guarantee , therefore, its coaxiality and precision are poor, which leads to poor consistency of the oil bearing in the motor

specific Embodiment 1

[0023] Such as figure 2 , image 3 As shown, this embodiment consists of a housing 1 and a plastic-sealed bearing device 2 . The middle part of the housing 1 is provided with a bearing device mounting seat 3 . The casing 1 is provided with a gap 11 , and a support bar 12 is formed between the gap 11 and the gap 11 , and the support bar 12 supports and fixes the bearing device mounting seat 3 . Only using the support bar 12 to support the bearing device installation seat 3 is beneficial to reduce the material cost of the housing. The bearing device mounting seat 3 is integrally formed with the housing 1 . The housing 1 is made of flame-retardant plastic material ABS or PC or PP. The plastic-sealed bearing device 2 is located in the bearing device mounting seat 3 . The fixed end cover 13 is embedded in the bearing device mounting seat 3 to fix the plastic-sealed bearing device 2 . The plastic-encapsulated bearing device 2 is made up of a plastic base and an oil-impregnate...

specific Embodiment 2

[0024] Such as Figure 4 As shown, the characteristics of this specific embodiment are: the bearing seat 6 of the plastic-sealed bearing device 2 and the bearing device mounting seat 3 are connected as a whole, and they are integrally formed and made together when the housing 1 is injected. The bearing seat 6 is integrally formed with the housing, so that the bearing seat 6 is coaxial with the bearing device mounting seat 3, thereby facilitating the rotating performance of the bearing. The parts of the oil cup 7 are matched with the bearing seat at the injection molded housing, and then fused together by ultrasonic welding process to form the bearing chamber cavity.

[0025] Except for the oil-impregnated bearing, all the constituent materials of the present invention can be injection molded by plastics. Favorable to reduce costs. Ideal replacement for existing motor covers.

Abstract

This invention discloses one plastic sealed axis device motor cover, which is characterized by the following: comprising shell with axis fixing socket, plastic axis device connected to the shell; the sealed axis device is fixed inside the axis device fixing socket; the axis device is fixed on the socket connected to the axis socket of the plastic axis device.

Description

technical field [0001] The invention relates to a motor cover, in particular to a motor cover with a bearing device. It belongs to the technical field of motor casings. Background technique [0002] In the prior art, the casings of commonly used electric fan motors, exhaust fan motors and other similar motors are made of sheet metal steel or cast aluminum alloy. When using sheet metal steel, because it is applied to the stretching process of metal sheet metal, parts products need to go through many complex processes such as cutting, drawing, replicating, shaping, finishing, punching, trimming, tapping, and electroplating. The process can be processed. The product yield is about 97%. The existing commonly used sheet metal motor casings have the disadvantages of high raw material cost, complicated processing technology, high processing cost, difficulty in ensuring the forming accuracy of sheet metal parts, poor consistency of finished product accuracy, and long production c...
