Abstract
The invention discloses a small-area contact chuck ball hinge friction pair structure, which comprises a chuck and a ball hinge, wherein a mounting hole is formed in the chuck; an annular contact zone arranged along the inner wall of the mounting hole is arranged on the inner wall of the mounting hole; the width of the annular contact zone is smaller than that of the inner wall of the mounting hole; the annular contact zone is raised from the inner wall of the mounting hole, and contacts with the surface of the ball hinge. According to the small-area contact chuck ball hinge friction pair structure, a contact friction part is changed into an annular zone shape on the basis of an original ball hinge chuck friction pair design, so that friction energy loss is reduced, reliability and stability are improved, machining difficulty is reduced, and the efficiency of a grinding procedure is improved.
Description
Technical field
The present invention relates to hydraulic test parts technical field, particularly to a kind of chuck ball pivot little contact area friction pair
Structure.
Background technology
Axial piston motor, plunger displacement pump are widely used in industrial hydraulic and walking Hydraulic Field.As in hydraulic system
The energy transmission of important component, axial piston motor and plunger displacement pump and energy loss are the emphasis of research.Chuck ball pivot rubs
Wiping pair is one of friction pair important in axial motor, plunger displacement pump, can guarantee that again it the while of how reducing its friction energy loss
Reliability and stability so that the research to it is significant.
At present, domestic production axial piston motor, plunger displacement pump producer in the research of chuck ball pivot friction pair more uses entirely
Contact or bump contact formula friction pair.This mode has obtained great guarantee in terms of reliability, but due to friction area
Excessive, partial frictional can be caused to lose.And abroad producer has the mode using linear contact lay in spherical hinge chuck friction pair.Although adopting
Using this way of contact, the energy loss that friction causes is minimum, but owing to its ratio pressure is very big, easily causes abrasion, reliability and
Stability aspect is poor, and the requirement to production technology is higher.
Summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of card little, that reliability is high and stability is strong that rubs
Little contact area friction pair structure is cut with scissors in dribbling.
For achieving the above object, the present invention uses following technical proposals: a kind of chuck ball pivot little contact area friction pair is tied
Structure, including chuck and ball pivot, described chuck is provided with installing hole, and the inwall of described installing hole is provided with one and sets along installing hole inwall
The ring shaped contact band put, the width of described ring shaped contact band protrudes peace less than the width of installing hole inwall, described ring shaped contact band
Dress hole inwall also contacts with the surface of ball pivot.
With improvement, the edge of described ring shaped contact band to the inner wall surface even transition of installing hole, described installing hole interior
Wall is the arc identical with ball pivot surface arc radian.
Preferably, the width of described ring shaped contact band is 0.5-0.8mm.
Preferably, the width of described ring shaped contact band is 0.5mm.
Preferably, the width of described ring shaped contact band is 0.8mm.
Preferably, the width of described ring shaped contact band is 0.65mm.
With improvement, described chuck at least ring shaped contact band portion carries out Nitrizing Treatment.
The invention has the beneficial effects as follows: contact, on the basis of original spherical hinge chuck design of friction pairs, is rubbed by the present invention
Part changes ring-band shape into, reduces friction energy loss, improves reliability and stability, reduces difficulty of processing simultaneously, improves and grinds
The efficiency of operation.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 be ring shaped contact band with ball pivot surface engagement structural representation.
Wherein 1. chuck, 2. ball pivot, 3. ring shaped contact band.
Detailed description of the invention
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, also may be used
To obtain other accompanying drawing according to these accompanying drawings.
A kind of chuck ball pivot little contact area friction pair structure as depicted in figs. 1 and 2, including chuck 1 and ball pivot 2, institute
Stating chuck 1 and be provided with installing hole, the inwall of described installing hole is provided with a ring shaped contact band 3 arranged along installing hole inwall, ring
The width of shape contact band 3 is less than the width of installing hole inwall, described ring shaped contact band protrusion installing hole inwall the table with ball pivot 2
Face contacts；The edge of ring shaped contact band 3 is to the inner wall surface even transition of installing hole, and the inwall of described installing hole is and ball pivot table
The arc that face arc radian is identical；The width of ring shaped contact band 3 can be 0.5mm, 0,65mm, 0.8mm and 0.5mm-0.8mm
In the range of any value；Chuck 1 entirety carries out Nitrizing Treatment.
Although the detailed description of the invention of the present invention is described by the above-mentioned accompanying drawing that combines, but not the present invention is protected model
The restriction enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme, and those skilled in the art are not
Need to pay various amendments or deformation that creative work can make still within protection scope of the present invention.
