Description
Technical field
This utility model belongs to oscillating bearing technical field and in particular to making reset joint by oneself.
Background technology
Oscillating bearing is a kind of spherical bearing, and its sliding contact surface is an Internal Spherical Surface and a spherical outside surface, fortune
Can be in arbitrarily angled rotary oscillation when dynamic, it adopts multiple special process process sides such as alramenting, fried mouth, edge pad, spraying
Method is made.It is big that oscillating bearing has a load-carrying ability, shock resistance, anticorrosive, wear-resistant, Self-aligning, the features such as lubricated.Close
The structure of bearings is simpler than rolling bearing, and it is mainly by an inner ring having spherical outside surface and an outer ring group having Internal Spherical Surface
Become.Oscillating bearing is generally used for the relatively low oscillating motion of speed (i.e. angular movement), because slidingsurface is spheric, also can be one
Determine in angular range, to make banking motion (i.e. regulation of mental activities motion), when support shaft and axle housing hole nonconcentricity are larger, remain to normal work
Make.
In prior art rare with the articulation structure that automatically resets, and be all to be made using springs such as metal spring or gas springs
For the power resetting, complex structure.
This utility model of Chinese Patent Application No. 201120531484.4 discloses a kind of reset joint, including by the first spiral shell
The candan universal joint that bar, cross axle and the second fork connect and compose, opens up first inner chamber in the first screw rod, install in first inner chamber
(the first back-moving spring and the first reseting sleeve, the outer end of the first reseting sleeve is externally provided with the first reset surface positioned at first inner chamber, and first is multiple
Plane is located between two first fork ears of the first screw rod；The end of the second fork ear is provided with the second reset end face, the second reset terminal
Face and the first reset facial plane cooperation.It is provided with reseting sleeve and back-moving spring, the reset surface of reseting sleeve and the reset terminal pitching ear
Facial plane coordinates.When external force makes fork rotate, reseting sleeve compression spring energy storage can be passed through, after external force is cancelled, spring can be released
Exoergic amount makes fork reset, and, reset surface and the cooperation of reset end face can ensure that fork recovers to initial position, meet user and wish
Hope that joint can automatically reset require.But the fork of this utility model can only swing it is impossible to swing solid angle in a plane.
Chinese Patent Application No.: 201520056250.7 this utility model are related to mechanical transmission member field, particularly relate to
And arrived a kind of ball-joint universal joint.This ball-joint universal joint includes two universal-joint forks and joint ball, and each universal-joint fork is equal
Including jaw and the clamp being oppositely arranged, jaw includes yoke, and described clamp is located on corresponding yoke, and the inner side of clamp is provided with
Ball-and-socket corresponding with joint ball, in addition, the inner side of clamp is provided with the surface of revolution of cone, the cone that the described surface of revolution is formed is certainly
Outwards become larger inside clamp, joint ball is stuck between the clamp of two universal-joint forks, the adjacent card of two universal-joint forks
The tangent laminating of the surface of revolution of plate.This joint has universal linkage function but do not have can reset function.
Utility model content
This utility model solves the above problems, and provides one kind to make reset joint by oneself.
The technical solution of the utility model automatically resets articulation structure as follows, including the first recessed shell, the second recessed shell, axle and bullet
Gonosome, the first described recessed shell and the described second recessed shell are in spherical shell shape, and the second recessed shell is embedded in the inwall of the first recessed shell, and described
The inwall of the first recessed shell can fit tightly the outer wall of the second described recessed shell, and described elastomer is fixed on the second described recessed shell
Inwall on, the first described recessed shell is provided with the first via, and the second described recessed shell is provided with the second via, described axle according to
Secondary pass through the first via, the second via to be connected with the first recessed shell, elastomer respectively, described axle and second cross interporal lacuna cooperation.
Of the present utility model to realize process as follows: the first described recessed shell is embedded in the second described recessed shell, and described the
Two recessed shell outer walls against the first recessed shell inwall and arbitrarily can swing in the first recessed shell, and axle sequentially passes through the first via, the second mistake
Hole is connected with the first recessed shell, elastomer respectively, because the second via is coordinated with shaft clearance, so the second recessed shell can be in the second via
Restriction in the range of rotate along the first recessed shell inwall, elastomer is fixed on the described inwall of the second recessed shell, and axle is worn successively
Cross the second via to be connected with elastomer, when the second recessed shell rotates along the first recessed shell inwall, axle keeps relative solid with the first recessed shell
Fixed position, then make elastomer that elastic deformation occurs, and elastically-deformable elastic force makes elastomer reply original shape, and elastomer returns
When restoring shape, also there is the relative position of elastic deformation front axle and the second recessed shell in elasticity recovery body for the axle affixed with elastomer, complete
Become to automatically reply process.
Brief description
Fig. 1 is the sectional view before specific embodiment assembling.
Fig. 2 is the sectional view after specific embodiment assembling.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is further described.
Be illustrated in figure 1 the sectional view before specific embodiment assembling, automatically reset articulation structure, including the first recessed shell 1, the
Two recessed shells 2, axle 4 and elastomer 3, are provided with the second dop 6, described axle 4 is in the second recessed shell 2 inside the second recessed shell 2 of axle 4
Side is provided with the second dop 6, is provided with cavity 8 and through hole 9 in described elastomer 3, and described cavity 8 is matched with the second dop 6,
Described through hole 9 one end is connected with the outside of elastomer 3, and described through hole 9 other end is connected with cavity 8, as shown in Fig. 2 second
Dop 6 may be stuck in cavity 8, and axle 4 sequentially passes through perforation 9, the second via 11, the first via 10, and axle 4 sets at the first recessed shell 1 end
