Abstract
A kind of bearing the utility model discloses bearing outer ring with positioning pin, including bearing outer ring, bearing inner race, the retainer being arranged between the bearing outer ring and bearing inner race and the rolling element between the bearing outer ring and bearing inner race is arranged in by the retainer, it is characterized in that, the bearing outer ring is equipped with a radial pin hole, there is a positioning pin in the radial pin hole interpolation, using interference fit between the radial direction pin hole and positioning pin；The positioning pin extends radially outwardly away, connect with bearing chamber inner hole.Positioning pin can prevent bearing outer ring from rotating in the utility model, to prevent that creep is occurred and is caused to generate fretting wear between bearing outer ring and bearing block by bearing outer ring, reduce temperature rise.Improve bearing working efficiency.
Description
Technical field
A kind of bearing the utility model relates to technical field of bearings more particularly to bearing outer ring with positioning pin.
Background technique
For existing conventional scroll bearing in order to guarantee certain working gap, the outer diameter of bearing outer ring is interior with bearing chamber inner hole
It is usually gap-matched between diameter.But it is gap-matched when between the outer diameter of bearing outer ring and the internal diameter of bearing chamber inner hole
When, as bearing inner race rotates, outer ring can generate creep, cause between outer ring and bearing chamber generate fretting wear, aggravation temperature rise,
Bearing working efficiency is reduced, abrasive grain can enter the situation that Bearing inner causes bearing life reduction even stuck when serious.
The utility model has carried out beneficial exploration and trial thus, has found result of the above problems, below will
The scheme to be introduced is generated under this background.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of axis with defect in view of the deficiencies of the prior art
Bearing of the bearing outer-ring with positioning pin.
The technical issues of the utility model is solved can be realized using following technical scheme:
A kind of bearing of the bearing outer ring with positioning pin, including bearing outer ring, bearing inner race, setting the bearing outer ring with
Retainer between bearing inner race and the rolling between the bearing outer ring and bearing inner race is arranged in by the retainer
Body, which is characterized in that the bearing outer ring is equipped with a radial pin hole, has a positioning pin in the radial pin hole interpolation, described
Using interference fit between radial pin hole and positioning pin；The positioning pin extends radially outwardly away, connect with bearing chamber inner hole.
Due to using technical solution as above, the utility model has the beneficial effects that: positioning pin in the utility model
Bearing outer ring can be prevented to rotate, to prevent that creep is occurred and generation between bearing outer ring and bearing block is caused to rub by bearing outer ring
Scouring damage, reduces temperature rise.Improve bearing working efficiency.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of bearing of the utility model bearing outer ring with positioning pin.
Fig. 2 is positioning pin scheme of installation.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
The utility model is further described in face.
Referring to Fig. 1 and Fig. 2, bearing of a kind of bearing outer ring with positioning pin shown in figure, including bearing outer ring 1, bearing
Inner ring 2, retainer 3, rolling element 4 and positioning pin 5.
It is respectively formed on the inner ring surface of bearing outer ring 1 and on the outer ring surface of bearing inner race 2 and rolls annular groove 4a, rolling element 4
It is arranged between bearing outer ring 1 and bearing inner race 2, and is located at the rolling rolled on annular groove 4a and bearing inner race 2 on bearing outer ring 1
In the raceway that rotating ring slot 4a is constituted, and mutually kept the same spacing by retainer 6.By in bearing outer ring 1 and bearing
The seal groove 6a for enclosing 2 two sides is equipped with sealing ring 6.
The radial pin hole 11 of certain depth is drilled on the outer peripheral surface of bearing outer ring 1, positioning pin 5 is inserted into radial pin hole 11
Interior and be interference fitted with positioning pin 5, positioning pin 5 exposes length B and the positioning pin 5 of radial pin hole 11 to define radial pin hole 11
Depth, define the position of radial pin hole 11 according to the central axis of positioning pin 5 and the distance between the end face A of bearing outer ring 1
It sets.
Bearing is installed in bearing chamber, when bearing outer ring 1 and bearing chamber inner hole (not shown) are gap-matched
When, positioning pin 5 can prevent bearing outer ring 1 rotate, thus avoid bearing outer ring 1 occur creep and with bearing block (not shown)
Between generate fretting wear, reduce temperature rise, improve working efficiency.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
