Abstract
The utility model discloses a kind of conical bearing retainer, including body, body is round table-like hollow stamping parts, its periphery is provided with some tapered pocket holes for being used to accommodate taper roller, body small end has radially inwardly extending, annular inside edge, and the big end of body has outside edge extend radially outward, annular;There is the raised line one extended along tapered pocket hole normal direction on the hole wall corresponding with taper roller small end of tapered pocket hole, there are two raised lines two extended along tapered pocket hole normal direction on the hole wall corresponding with the big end of taper roller of tapered pocket hole.The utility model is compared with common conical bearing retainer, and it has, and manufacture efficiency is high, noise is low, saves the advantages of material.
Description
Technical field
Technical field of bearings is the utility model is related to, especially a kind of conical bearing retainer.
Background technology
Conical bearing retainer is sleeved on the inner ring of conical bearing, for isolating taper roller.Common conical bearing
Retainer (as shown in Figure 1) is round table-like hollow and thin-walled stamping parts, typically using punching press --- turning process manufactures, car
The purpose for cutting processing is to put down the big end end car of retainer after punching press, and turnery processing production efficiency is relatively low, and machining accuracy
Also it is not high enough;When conical bearing runs at high speed, noise is larger;Common conical bearing retainer material thickness is larger.
Utility model content
The technical problems to be solved in the utility model is:Overcome deficiency in the prior art, there is provided a kind of low noise, efficient
Conical bearing retainer.
Technical scheme is used by the utility model solves its technical problem:A kind of conical bearing retainer, including this
Body, body are round table-like hollow stamping parts, and its periphery is provided with some tapered pocket holes for being used to accommodate taper roller, body small end
With radially inwardly extending, annular inside edge, the big end of body has outside edge extend radially outward, annular;
There is the raised line one extended along tapered pocket hole normal direction, tapered pocket hole on the hole wall corresponding with taper roller small end of tapered pocket hole
There are two raised lines two extended along tapered pocket hole normal direction, using two raised lines on hole wall corresponding with the big end of taper roller
Two purpose is to avoid the depression at the big end of taper roller.
The cross section of the raised line one and raised line two is curved, the protrusion height of raised line one or raised line two for 0.2mm~
0.3mm, raised line one and raised line two are connected as a single entity with body.
The beneficial effects of the utility model are:For the utility model compared with common conical bearing retainer, it has system
The advantages of making low efficiency high, noise, saving material.
Brief description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of common conical bearing retainer;
Fig. 2 structural representations of the present utility model.
In figure:1. tapered pocket hole;2. inside edge;3. outside edge;4. raised line one;5. raised line two.
Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of conical bearing retainer as shown in Figure 2, including body, body are round table-like hollow stamping parts, outside it
It is provided with some tapered pocket holes 1 for being used to accommodate taper roller (not shown) week;
Body small end has radially inwardly extending, annular inside edge 2, and the big end of body, which has, to be extended radially outward
, annular outside edge 3, the outside edge 3 adds the rigidity of body, thus the material thickness of body can be taken the circumstances into consideration to be thinned;By
In employing outside edge 3, the big end of the body after punch forming is just not required to carry out turnery processing, only need to use trimming process,
Production efficiency thus is improved, and no longer needs lathe processing equipment;
There is the raised line one extended along tapered pocket hole normal direction on the hole wall corresponding with taper roller small end of tapered pocket hole 1
4, there are on the hole wall corresponding with the big end of taper roller of tapered pocket hole 1 two raised lines 25 extended along tapered pocket hole normal direction,
When conical bearing works, the taper roller in body tapered pocket hole 1 starts to rotate, its large end face and small end face respectively with tapered pocket
Raised line 1 and the contact of raised line 25 on the hole wall of hole 1, raised line 1 and raised line 25 reduce the contact surface of taper roller and body
Product, thus reduce noise when conical bearing works.
The cross section of the raised line 1 and raised line 25 is curved, and raised line 1 or raised line 25 protrude the hole wall of tapered pocket hole 1
Height be 0.2mm~0.3mm.
For above-mentioned embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with this skill
The personage of art can understand content of the present utility model and be carried out, and protection model of the present utility model can not be limited with this
Enclose, all equivalent change or modifications made according to the utility model Spirit Essence, should all cover in protection model of the present utility model
In enclosing.
