Abstract
Title: Device for Limiting Bearing and Fixing Brush Carrier of Motor Abstract The present invention discloses a device for limiting a bearing and fixing a brush carrier of a motor. The motor comprises a shell, an end cover and a motor shaft. A brush carrier is mounted inside the shell. The end cover is provided with a recess in which a bearing is provided. The motor shaft passes through the brush carrier and a central hole of the bearing. The device comprises a bearing fixing plate, one side of which compresses the brush carrier while the other side compresses the bearing.
Description
Description Device for Limiting Bearing and Fixing Brush Carrier of Motor Technical Field of the Invention The present invention relates to the field of motors, and particularly to device for limiting a bearing and fixing a brush carrier of a motor. Background of the invention For a motor, both the brush carrier and the carbon brush are quite important components. When there is no appropriate brush carrier, the carbon brush cannot take full advantage of its excellent characteristics, or even greatly influences the performance and service life of the motor itself, no matter how excellent the characteristics of the carbon brush are. The brush carrier and bearing of an existing motor are separately fixed. Such a motor is relatively complicated in structure, and it is difficult to replace the brush carrier and the bearing. Summary of the Invention To solve the technical problems in the prior art, the present invention provides a device for limiting a bearing and fixing a brush carrier of a motor, including a shell, an end cover and a motor shaft. A brush carrier is mounted inside the shell. The end cover is provided with a recess in which a bearing is provided. The motor shaft passes through the brush carrier and a central hole of the bearing. The device includes a bearing fixing plate, one side of which compresses the brush carrier while the other side compresses the bearing. Further, notches are provided at opposite ends of the shell. The brush carrier is provided with two first lugs, the first lugs being provided with first holes, respectively. The bearing fixing plate is provided with two second lugs, 1 the second lugs being provided with second holes, respectively. The first lugs and the second lugs are embedded into the notches. Further, the brush carrier and the bearing fixing plate are fixed onto the shell by inserting fastening screws into the first holes and the second holes. In the device for limiting a bearing and fixing a brush carrier of a motor provided by the present invention, the brush carrier and the bearing fixing plate are fitted with the notches of the motor shell, the bearing fixing plate and the brush carrier are axially fastened by fastening screws, and the bearing is axially fixed by the bearing fixing plate. Therefore, the structure is simple, and it is convenient to replace the bearing and the brush carrier. Brief Description of the Drawing Fig. 1 is a schematic diagram of a motor having a device for limiting a bearing and fixing a brush carrier according to the present invention; Fig. 2 is a top view of the motor having a device for limiting a bearing and fixing a brush carrier according to the present invention; Fig. 3 is a sectional view of the motor having a device for limiting a bearing and fixing a brush carrier according to the present invention; Fig. 4 is a schematic diagram of a shell; Fig. 5 is a schematic diagram of a brush carrier; and Fig. 6 is a schematic diagram of a bearing fixing plate. Detailed Description of the Invention The present invention will be further described as below with reference to the accompanying drawings. As shown in Figs. 1-3, a motor having the device for limiting a bearing and fixing a brush carrier provided by the present invention includes a shell 1, 2 an end cover 2 and a motor shaft 3. A brush carrier 4 is mounted inside the shell. The end cover 2 is provided with a recess in which a bearing 5 is provided. The motor shaft 3 passes through the brush carrier 4 and a central hole of the bearing 5. One side of a bearing fixing plate 6 compresses the brush carrier 4, while the other side thereof compresses the bearing 5. As shown in Figs. 4-6, notches 7are provided at opposite ends of the shell 1. The brush carrier 4 is provided with two first lugs 8, the first lugs 8 being provided with first holes 8. The bearing fixing plate 6 is provided with two second lugs 10, the second lugs being provided with second holes 11. The first lugs 8 and the second lugs 10 are embedded into the notches 7, and fix onto the shell 1 by inserting fastening screws 12 into the first holes 9 and the second holes 11. 3
