Abstract
The utility model discloses an automobile motor bearing fixing structure, which comprises a shell part formed by adopting a deep drawing process and a bearing chamber positioned in the center of the shell part; the bearing chamber is provided with a step which is connected with the shell part and is connected with the bearing chamber into a whole, and the bearing chamber is characterized in that a riveting point is punched at one end of the bearing chamber connected with the shell part after the bearing is pressed into the bearing chamber, and the riveting point and the step fix and axially limit the bearing together. The utility model discloses fix the bearing and the axial is spacing jointly through the multiple spot riveting and with the step cooperation after the bearing pressure equipment, reduces the technology complexity, reduces the use of bearing baffle, reduce cost.
Description
Technical Field
The utility model relates to an automobile motor technical field, in particular to automobile motor bearing fixed knot constructs.
Background
At present, a bearing in an automobile motor is axially limited and fixed by a bearing flange, and the bearing flange is fixed on a shell by a fastener, so that the manufacturing process is complex and uneconomical. In addition, the weight of the automobile motor is increased after the bearing flange is added, and the requirement of light weight of the automobile at present is not met.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that it is complicated to adopt the bearing flange to carry out the manufacturing process that the axial was spacing to bring to the bearing among the current automobile motor, uneconomical problem and provide an automobile motor bearing fixed knot and construct.
The utility model discloses the technical problem that will solve can realize through following technical scheme:
a bearing fixing structure of an automobile motor comprises a shell part formed by adopting a deep drawing process and a bearing chamber positioned in the center of the shell part; the bearing chamber is provided with a step which is connected with the shell part and is connected with the bearing chamber into a whole, and the bearing chamber is characterized in that a riveting point is punched at one end of the bearing chamber connected with the shell part after the bearing is pressed into the bearing chamber, and the riveting point and the step fix and axially limit the bearing together.
In a preferred embodiment of the present invention, the rivet points are a plurality of rivet points, and the bearing chamber is uniformly distributed in a circumferential direction of an end connected to the housing portion.
Since the technical scheme as above is used, the utility model discloses fix the bearing and axial spacing jointly through the multiple spot riveting and with the step cooperation after the bearing pressure equipment, reduce technology complexity, reduce the use of bearing baffle, reduce cost!

Detailed Description
The invention is further described below in conjunction with the appended drawings and detailed description.
Example 1
Referring to fig. 1 and 2, the bearing fixing structure of the motor vehicle shown in the figure comprises a housing portion 10 formed by a deep drawing process and a bearing housing 20 located at the center of the housing portion 10, wherein the bearing housing 20 is provided with one end 21 connected with the housing portion 10 facing the outside of the housing portion 10.
The bearing chamber 20 has one end 21 connected to the housing portion 10 and a step 21a integrally connected to the bearing chamber 20. A bearing 30 is pressed into the bearing chamber 20.
The characteristics of this embodiment are: the bearing stop is eliminated, after the bearing 30 is pressed into the bearing chamber 20, a riveting point 22a is punched at one end 22 of the bearing chamber 20 connected with the housing part 10, and the riveting point 22a and the step 21a jointly fix and axially limit the bearing 30.
In addition, the riveting points 22a are a plurality of points, and are uniformly distributed in the circumferential direction of the end 22 of the bearing chamber 20 connected with the shell part 10, so that the riveting points can be matched with the step 21a to uniformly apply acting force to the bearing 30, ensure that the bearing 30 cannot be eccentric, and keep good concentricity with the shell part 10.
Example 2
Referring to fig. 3 and 4, the bearing fixing structure of the motor vehicle shown in the figure includes a housing portion 10a formed by a deep drawing process and a bearing housing 20a located at the center of the housing portion 10a, wherein the bearing housing 20a is provided with one end 21a connected to the housing portion 10a facing the inside of the housing portion 10 a.
The bearing chamber 20a has one end 21a connected to the housing portion 10a, and a step 21aa integrally connected to the bearing chamber 20 is provided. A bearing 30a is pressed into the bearing chamber 20 a.
The characteristics of this embodiment are: with the bearing stopper removed, after the two bearings 30a are pressed into the bearing chamber 20a, a rivet point 22aa is punched at one end 22a of the bearing chamber 20a connected to the housing portion 10a, and the rivet point 22aa and the step 21aa fix and axially limit the bearings 30a together. The two bearings 30a are separated by a sleeve 30 b.
In addition, the riveting points 22aa are provided in a plurality, and are uniformly distributed in the circumferential direction of the end 22a of the bearing chamber 20a connected with the housing portion 10a, so that the riveting points can be matched with the step 21aa to apply acting force to the bearing 30a in a balanced manner, thereby ensuring that the bearing 30a is not eccentric and keeps good concentricity with the housing portion 10.
