Description
Technical field
The present invention relates to a kind of spacing adjusting apparatus of bearing.
Background technology
Bearing is that part that is fixed and reducing load coefficient of friction is played in various mechanical transmission courses, when other parts exist
When producing relative motion each other on axle, for reducing what the coefficient of friction in power transmission process and holding shaft center were fixed
Parts.During machine driving, axle and bearing can produce vibration, particularly in the transmission process of big load.It is existing
The mode for preventing bear vibration be using top pressure end insert bearing seat bearing mounting hole in bearing (ball) cover in axial side
To compression bearing outer ring, and the outward flange part of bearing (ball) cover is bolted on bearing seat.But due to bearing,
Can there is certain foozle in bearing (ball) cover and bearing seat, so in some cases the top pressure end of bearing (ball) cover with
Can there are some gaps between the corresponding end-faces of the outer ring of bearing unavoidably, and as bearing (ball) cover has been fixed with bearing seat,
Now bearing can not be compressed by adjusting the axial location of bearing (ball) cover, bearing is caused due to the presence of fit clearance
Vibration will be produced at work, vibration not only reduces the rotation precision of axle, and can accelerate the abrasion of bearing, shorten bearing
Service life.In addition, using the bearing thickness of different model also have difference, also resulting in different bearings needs supporting making
Compressed with various sizes of bearing (ball) cover, so as to improve cost.
The content of the invention
It is an object of the invention to provide a kind of can ensure by axially adjustable that the cooperation with bearing outer ring is compressed
The spacing adjusting apparatus of bearing.
To achieve these goals, the present invention is adopted the following technical scheme that：
The spacing adjusting apparatus of bearing, including the bearing seat with left and right directions inner through hole, the bearing seat it is interior
Hole Screw assembly has the adjusting sleeve that pressuring action is played to bearing, and the adjusting sleeve outer peripheral face is provided with external screw thread, the adjusting sleeve
Left end radially slides assembling along endoporus with the locating surface for coordinating with bearing outer ring end face top pressure, on the bearing seat
There is feather key, on the adjusting sleeve outer peripheral face, be additionally provided with the feather key insertion for limiting adjusting sleeve rotation of left and right directions extension
Stopper slot.
The adjusting sleeve includes plug screw and adjusting pad, and the adjusting pad is fixedly connected on plug screw right-hand member by stud, described
Locating surface is located at plug screw left end, and on the outer peripheral face of plug screw, the stopper slot is arranged on the periphery of adjusting pad to the external screw thread
On face.
The plug screw left end is provided with annular boss, annular end face of the locating surface for annular boss left end.
The plug screw right-hand member is provided with the vexed hole of screw thread of the confession stud screw-in that left and right extends, and the adjusting pad is provided with a left side
The screwed hole screwed in for the stud corresponding with the vexed hole of the screw thread of right insertion.
The bearing seat is bearing holder (housing, cover), and on the opening in the endoporus of bearing holder (housing, cover) right-hand member, envelope is provided with bearing capping.
Beneficial effects of the present invention are：By axle and assembling when the bearing of axle one end is arranged on bearing seat, by rotation
Modulation is a whole set of to be adjusted its axial location and makes the locating surface of its end compress bearing outer ring, by slidable fit on bearing seat
In stopper slot in feather key one end insertion adjusting sleeve.Feather key limits the rotation of adjusting sleeve, and adjusting sleeve compresses bearing outer ring
Rotationally and axially moving for bearing outer ring is limited, so as to prevent the vibration of bearing, the abrasion of bearing is reduced, is extended axle
The service life held, while also maintaining the normal operation position and rotation precision of axle.
Description of the drawings
Fig. 1 is the structural representation of embodiments of the invention.
