Hold, but this its amplitude of fluctuation of crescent moon bearing is fixed.When needing to manufacture the crescent moon bearing of different amplitudes of fluctuation, it is necessary to again
Production mould is manufactured, production cost is higher.In addition the crescent moon bearing for fixing the amplitude of oscillation is limited to usage scenario, product versatility compared with
It is low.
Utility model content
(1) technical problems to be solved
In view of the deficienciess of the prior art, to provide a kind of use range wide, convenient for production adjustable for the utility model
Bearing.
(2) technical scheme
To reach above-mentioned purpose, the utility model provides a kind of adjustable bearing, including bearing outer ring and roller are kept
Device, the side of the roller retainer is provided with more than two swing connector mounting seats, described to swing connection mounting seat bag
A swinging chute and a rotation hole are included, the rotation hole and bearing are axially in parallel, and the swinging chute is in arcuation and all along bearing
To distribution, the swinging chute is connected with the rotation hole and runs through the roller retainer, and pendulum is provided with the rotation hole
Moving axis, the swinging axle are provided with pin-and-hole, and pin, one end and the bearing outer ring stationary phase of the pin are provided with the pin-and-hole
Even, the other end of the pin is placed in the swinging chute.
Further, the swing connector mounting seat has two.
Further, two connector mounting seats that swing are located at described roller retainer the same side.
Further, the bearing outer ring is provided with two pin mounting holes, and the pin is arranged on the pin mounting hole
It is interior.
Further, the bearing outer ring has multiple, the distance between two pin mounting holes on the multiple bearing outer ring
It is different.
Further, one end of the roller retainer is provided with reinforcement, and the swing connector mounting seat is arranged on institute
State on reinforcement.
(3) beneficial effect
The utility model adjustable shaft bearing structure is novel, ingenious in design, by adjusting pin on bearing outer ring
Position, the amplitude of fluctuation of roller retainer can be adjusted, the use range of crescent moon bearing can not only be expanded, moreover it is possible to which reduction is produced into
This, saves mould development cost.
Brief description of the drawings

Fig. 4 is the structural representation of swinging axle in the utility model.
Wherein, 1 is roller retainer, and 2 be bearing outer ring, and 3 is swing connector mounting seat, and 4 be rotation hole, and 5 enclose and beat up pendulum
Dynamic groove, 6 be reinforcement, and 7 be pin mounting hole, and 8 be swinging axle, and 9 be pin-and-hole.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
A kind of structure of adjustable bearing of the present utility model as depicted in figs. 1 and 2, including protect by bearing outer ring 2 and roller
Holder 1, the side of the roller retainer 1 is provided with more than two swing connector mounting seats 3, described to swing connection installation
Seat 3 includes a swinging chute 5 and a rotation hole 4, and the rotation hole 4 and bearing are axially in parallel, the swinging chute 5 be in arcuation simultaneously
Circumferentially distributed along bearing, the swinging chute 5 is connected with the rotation hole 4 and runs through the roller retainer 1, the rotation hole
Swinging axle 8 is installed, the swinging axle 8 is provided with pin-and-hole 9, pin, one end of the pin are provided with the pin-and-hole 9 in 4
It is fixedly linked with bearing outer ring 2, the other end of the pin is placed in the swinging chute 5.
In the present embodiment, the swing mounting seat of connector 3 has two.
In the present embodiment, the two swing connectors mounting seat 3 is located at described the same side of roller retainer 1.
In the present embodiment, the bearing outer ring 2 is provided with two pin mounting holes 7, and the pin is arranged on the pin
In post mounting hole 7.
In the present embodiment, the bearing outer ring 2 has multiple, on the multiple bearing outer ring 2 two pin mounting holes 7 it
Between distance it is different.
In the present embodiment, one end of the roller retainer 1 is provided with reinforcement 6, the swing connector mounting seat 3
It is arranged on the reinforcement 6.
In use, by being that can be achieved to adjust the amplitude of fluctuation of crescent moon bearing from different bearing outer rings.Work as pin
The spacing of mounting hole 7 is identical with the spacing of connector mounting seat 3 is swung, and now amplitude of fluctuation is maximum, when diminution pin mounting hole 7
Spacing or the spacing for expanding pin mounting hole 7, it can all reduce the amplitude of fluctuation of crescent moon bearing.
Different from traditional crescent moon bearing, the utility model adjustable bearing only needs a kind of fixed roller retainer of production
The crescent moon bearing of the different amplitudes of oscillation can be manufactured.Because roller retainer is complicated, mould development is difficult, therefore the utility model
Can solve production cost significantly.And bearing outer ring development cost is relatively low accordingly, all kinds can be conveniently produced
Bearing outer ring.Multiple bearing outer rings alternatively selected expand the scope of application of crescent moon bearing significantly.
The beneficial effects of the utility model：Structure is novel, ingenious in design, by adjusting pin on bearing outer ring
Position, the amplitude of fluctuation of roller retainer can be adjusted, the use range of crescent moon bearing can not only be expanded, moreover it is possible to which reduction is produced into
This, saves mould development cost.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as the scope of protection of the utility model.
