Description
Technical field
The present invention relates to a kind of articulated structures, more specifically to a kind of locking articulated structure of antifriction.
Background technique
Articulated structure is widely applied in mechanical equipment to realize the relative rotations of two connecting components, articulated structure mainly by
The composition such as pin shaft, axle sleeve, fixing component, revolving member, end cap, bolt.Pin shaft is radially contacted with fixing component axis hole, pin shaft axis
One side surface of shoulder and fixing component is axially contact, snap-gauge or bolt limitation pin shaft rotation in fixing component；Pin shaft end with
End cap is bolted, and there are gap in end cap and shaft end, convenient for the axially contact fastening in another side surface of end cap and fixing component.
Revolving member peg in hole operation has axle sleeve, and pin shaft is radially contacted with axle sleeve, and pin shaft can be rotated mutually with axle sleeve, realize fixing component with
The rotating function of revolving member.Fixing component and revolving member have axial gap, can adjust gap size by adjusting padding.By
In fixing component axis hole and pin shaft, there are minim gaps, and when articulated structure is when receiving load is excessive, pin shaft drives bolt opposite
End cap translation or rotation, the relative motion of bolt and end cap cause bolt gradually to loosen.Articulated structure bolt of cover easily loosens, drop
Low product reliability, cannot meet the needs of customers.
Summary of the invention
The technical problem to be solved by the present invention is to ask for pin shaft in existing articulated structure with what end end cap was easy to loosen
Topic, and a kind of locking articulated structure of antifriction is provided.
The present invention is to realize that the technical solution of its purpose is such that provide a kind of locking articulated structure of antifriction, including consolidate
Determine component, revolving member, pin shaft, the fixing component has upper hinge plate and a lower hinge plate, the revolving member be located at upper hinge plate and
Between lower hinge plate, upper hinge plate, revolving member are provided with coaxial axis hole on lower hinge plate, and the pin shaft passes through described from top to bottom
The lower section of upper hinge plate, revolving member, the lower axis hole cut with scissors on plate, the lower hinge plate is equipped with end cap, and the end cap passes through thread mechanism
It is fixedly mounted on the lower end of pin shaft；It is characterized in that being equipped with annular in shape and center between end cap and lower hinge plate is located at the pin shaft
The antifriction part in axle center, the lower end of pin shaft described in the antifriction part ring set annular in shape, the upper side of the antifriction part and downside point
Upper side not with the downside of the lower hinge plate and end cap is in close contact.In the present invention, antifriction part is by end cap and lower hinge plate
Be spaced apart plays the role of axially supporting, and reduces the frictional force or friction torque of the relatively fixed component movement of end cap, can allow
Pin shaft end, end cap keep moving synchronously substantially；The radial force or peripheral force almost all of pin shaft end are undertaken by fixing component,
Thread mechanism between end cap and pin shaft be solely subjected to axial force and translation, rotation it is relatively fewer under the conditions of, thread mechanism is not easy
It loosens, the anti-loosening property of articulated structure improves.
In the above-mentioned locking articulated structure of antifriction, the antifriction part be rolling friction pair be, for example, thrust angular contact bearing or
Axial contact bearing or self-aligning thrust roller bearing or thrust ball bearing or tapered roller bearing or angular contact ball bearing.Institute
It states antifriction part and is also possible to sliding friction pair, which is by under self friction coefficient ratio end cap upper side and lower hinge plate
Made by the small low-friction material of coefficient of friction between side；Antifriction part can also be antifriction sliding shoe, the antifriction sliding
The coefficient of friction between coefficient of friction or the antifriction sliding shoe and lower hinge plate downside between block and end cap upper side is less than
Coefficient of friction between end cap and fixing component.
In the above-mentioned locking articulated structure of antifriction, the thread mechanism includes the threaded hole being arranged on the pin shaft lower end surface
With the bolt of cover for being fixedly connected with the end cap with institute pin shaft with threaded hole cooperation, the upper side of the end cap with it is described
The end face of pin shaft has gap.Or thread mechanism includes that the screw thread of the pin shaft lower end side is arranged in and is threadedly engaged with this
End cover nut, the end cap central is equipped with axis hole, and the lower end of the pin shaft passes through axis hole and the end cap on the end cap
Nut matches.
Compared with prior art, the present invention designing antifriction part in articulated structure of the present invention, the relatively fixed structure of end cap is reduced
The frictional force or friction torque of part, end cap, pin shaft and realizing substantially for the thread mechanism between them move synchronously, reduce
The relative motion of end cap and thread mechanism reduces a possibility that thread mechanism loosens.
