Description
Technical field
The utility model is related to bearing shell boring die for processing.
Background technology
Bearing shell is the part of sliding bearing and journal contact, and shape is the semi-cylindrical of tiles, unusual light, bush material
Usual softer, inner cylinder face（Bearing shell inner wall）It should not be processed with filing, boring, Buddha's warrior attendant boring, scraping or grinding may be employed
Method is processed.
Bearing shell boring die for processing is common bearing shell processing mold, and existing bearing shell boring die for processing generally comprises
For placing the bearing shell placing groove of bearing shell, the inner wall of bearing shell placing groove is semi-cylindrical, and bearing shell is fixed in bearing shell placing groove, axis
Watt the inner wall of outer wall and bearing shell placing groove recline, boring processing can be carried out to the inner wall of bearing shell.
But the bearing shell that existing bearing shell boring die for processing is processed, wall thickness is single, i.e., half bearing thickness is axial along bearing shell
It is consistent, bearing shell is used with axle journal assembling, easily generates eccentric wear.
Initial stage break-in is adapted in order to avoid eccentric wear and quickly, the wall thickness of bearing shell will be handled especially, make half bearing thickness along axis
To gradual change, bearing shell axial direction thick middle, axial both ends are thin, and carrying is uniform when such bearing shell works, and can effectively avoid eccentric wear, and can be more
It is suitble to initial stage break-in soon.
Therefore new bearing shell boring die for processing is needed, in bearing shell right boring bearing shell is made to be deformed vertically.
Utility model content
The purpose of this utility model is to provide a kind of bearing shell boring die for processing, can produce wall thickness and become vertically
The bearing shell of change.
To achieve the above object, the technical solution of the utility model is a kind of bearing shell boring die for processing of design, including
Die main body, die main body are equipped with to place the bearing shell placing groove of bearing shell, and bearing shell placing groove is straight slot, and bearing shell placing groove
Inner wall is semi-cylindrical；
The axial both ends of bearing shell placing groove inner wall offer semi-circular shape raised line fixing groove respectively, and raised line fixing groove is along bearing shell
Placing groove inner wall it is circumferentially disposed, and raised line fixing groove be straight slot；
The semi-circular shape raised line set in the same direction with it is installed, and raised line protrudes from bearing shell placing groove in raised line fixing groove
Inner wall.
Preferably, through hole, through hole axle center and the axis perpendicular of bearing shell placing groove inner wall are additionally provided on bearing shell placing groove inner wall.
Preferably, through hole is located at the axial middle part of bearing shell placing groove inner wall, and through hole is located at the week of bearing shell placing groove inner wall
To middle part.
Preferably, the raised line fixing groove at bearing shell placing groove inner wall axial direction both ends is symmetrical arranged with through hole.
Preferably, raised line is fixed together with raised line fixing groove.
The advantages of the utility model and advantageous effect are：A kind of bearing shell boring die for processing is provided, can be produced
The axially varying bearing shell of wall thickness.
Bearing shell to be processed is fixed in bearing shell placing groove, and bearing shell is set in the same direction with bearing shell placing groove, the outer wall of bearing shell with
The raised line at bearing shell placing groove inner wall axial direction both ends reclines, in bearing shell right boring, the raised line energy at bearing shell placing groove inner wall axial direction both ends
Bearing shell is deformed, produces the axially varying bearing shell of wall thickness, such bearing shell can prevent unbalance loading, and can quickly be suitble to
Initial stage break-in.
Unlike material may be employed with die main body in raised line, with cost-effective.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and the protection model of the utility model cannot be limited with this
It encloses.
The utility model specific implementation technical solution be：

The axial both ends of 2 inner wall of bearing shell placing groove offer semi-circular shape raised line fixing groove 3,3 edge of raised line fixing groove respectively
2 inner wall of bearing shell placing groove it is circumferentially disposed, and raised line fixing groove 3 be straight slot；
The semi-circular shape raised line 4 set in the same direction with it is installed, and raised line 4 protrudes from bearing shell placement in raised line fixing groove 3
The inner wall of slot 2.
Preferably, through hole 5,5 axle center of through hole and the axle center of 2 inner wall of bearing shell placing groove are additionally provided on 2 inner wall of bearing shell placing groove
Vertically.
Preferably, through hole 5 is located at the axial middle part of 2 inner wall of bearing shell placing groove, and through hole 5 is located at 2 inner wall of bearing shell placing groove
Circumferential middle part.
Preferably, the raised line fixing groove 3 at 2 inner wall axial direction both ends of bearing shell placing groove is symmetrical arranged with through hole 5.
Preferably, raised line 4 is fixed together with raised line fixing groove 3.
