Description
Technical field
The utility model relates to the spacing regulating device of a kind of bearing.
Background technique
Bearing is in various mechanical transmission courses, to work the parts of fixing and reducing load friction factor, in the time that other parts produce relative movement each other on axle, is used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.In mechanically operated process, axle and bearing can produce vibration, particularly in the transmission process of large load.The existing mode that prevents bear vibration is to adopt top pressure side portion to insert bearing (ball) cover in the bearing mounting hole of bearing seat at axial direction compression axis bearing outer-ring, and the outward flange part of bearing (ball) cover is to be bolted on bearing seat.But because bearing, bearing (ball) cover and bearing support cognition exist certain foozle, between the top pressure side portion of bearing (ball) cover and the corresponding end-faces of the outer ring of bearing, can there are unavoidably some gaps so in some cases, and because bearing (ball) cover has been fixed with bearing seat, now can not bearing be compressed by the axial position of adjusting bearing (ball) cover, because causing bearing, the existence of matching gap will produce at work vibration, vibration not only makes the rotation precision of axle reduce, and can accelerate the wearing and tearing of bearing, shorten the working life of bearing.In addition, the bearing thickness of the different model of use also has difference, and the bearing (ball) cover that also can cause different bearings need to support the use different size compresses, thereby raises the cost.
Summary of the invention
The purpose of this utility model is to provide a kind of and can ensures and the spacing regulating device of bearing compressing that coordinates of bearing outer ring by axial adjustment.
To achieve these goals, the utility model adopts following technological scheme:
The spacing regulating device of a kind of bearing, comprise the bearing seat with left and right directions inner through hole, the inner hole thread of described bearing seat is equipped with the adjusting sleeve that bearing is played to pressuring action, described adjusting sleeve outer circumferential face is provided with outside thread, described adjusting sleeve left end have for the locating face of bearing outer ring end face top press fit, on described bearing seat, be equipped with feather key along radially sliding of endoporus, on described adjusting sleeve outer circumferential face, be also provided with the restraining groove that supplies the feather key that limits adjusting sleeve rotation to insert that left and right directions extends.
Described adjusting sleeve comprises plug screw and spacer, and described spacer is fixedly connected on plug screw right-hand member by double-screw bolt, and described locating face is located at plug screw left end, and described outside thread is located on the outer circumferential face of plug screw, and described restraining groove is arranged on the outer circumferential face of spacer.
Described plug screw left end is provided with annular boss, and described locating face is the annular end face of annular boss left end.
Described plug screw right-hand member is provided with the vexed hole of screw thread that the described double-screw bolt of the confession of extending left and right screws in, the tapped hole that the described double-screw bolt of the confession corresponding with the vexed hole of described screw thread connecting about described spacer is provided with screws in.
?the beneficial effects of the utility model are: when axle and the bearing that is assemblied in axle one end are arranged on bearing seat, the locating face compression axis bearing outer-ring of being adjusted its axial position and made its end by rotation adjusting sleeve, insert in the restraining groove in adjusting sleeve the feather key one end by slidable fit on bearing seat.Feather key has limited the rotation of adjusting sleeve, adjusting sleeve compression axis bearing outer-ring has limited the rotation of bearing outer ring and has moved axially, thereby has prevented the vibration of bearing, has reduced the wearing and tearing of bearing, extend the working life of bearing, also kept normal operation position and the rotation precision of axle simultaneously.
Brief description of the drawings
Fig. 1 is embodiment's of the present utility model structural representation.
Embodiment
The embodiment of the spacing regulating device of a kind of bearing of the utility model, as shown in Figure 1: this device comprises the bearing seat of the endoporus with left and right directions perforation, with the plug screw 4 to 7 pressuring actions of bearing of bearing seat inner hole thread assembling, the bearing capping 6 that on the opening that limits plug screw 4 spacer 3 being threaded with adjustment plug screw 4 that rotate and be located at bearing seat endoporus, envelope is established.
Wherein bearing seat is bearing housing 1, bearing housing 1 left part inner hole wall is as supporting for bearing 7 outer ring outer circumferential faces the locating face coordinating, right side part endoporus is the tapped hole coordinating for plug screw 4 rotations, and the right part of bearing housing 1 is provided with the guiding groove that radially slides cooperation for feather key 2.Plug screw 4 has the through hole penetrating for axle 8 that left and right connects, and plug screw 4 left ends are provided with annular boss 41, and annular boss 41 left ends have the locating face for right side, the outer ring top press fit of bearing 7, and plug screw 4 right-hand members are circumferentially interval with the two vexed holes of screw thread of inserting for double-screw bolt 5.
Spacer 3 is circle structure, spacer 3 end faces be provided with plug screw 4 on the tapped hole that matches of tapped hole that arranges, the restraining groove 31 that has the left and right perforation coordinating for feather key 2 blocks on spacer 3 outer circumferential faces, spacer 3 has the through hole penetrating for axle 8 that left and right connects.Spacer 3 is fixed together with plug screw 4 adjusting sleeve that is configured for compression axis bearing outer-ring by double-screw bolt 5, feather key 2 radially slides in the guiding groove that is assemblied in bearing housing 1, inserts the rotation with restriction spacer 3 and plug screw 4 in the restraining groove 31 being arranged on spacer 3 by feather key 2.
Adjusting sleeve in this above-described embodiment, to adopt plug screw and spacer by the Split type structure of Stud connection, spacer can be changed, install with the bearing that meets different model, and the restraining groove of different spacers can be located at different positions, be inserted in restraining groove to meet the bond energy that leads in the time adjusting plug screw.Certainly in other embodiments, adjusting sleeve also can not arrange spacer and only be made up of plug screw or plug screw and spacer are made of one to structure, now adopts restraining groove to be arranged on the outer circumferential face of plug screw or to be located on external thread section and all can.
