In universal drive shaft be ball universal drive shaft, ball universal drive shaft of the prior art typically with one bowl-shape resilient sleeve seal internal grease,
Resilient sleeve small end is contained in connecting rod, big end hold-down ring and petal joint compression, and resilient sleeve is typically made with rubber, due to
In using, resilient sleeve swings back and forth along with connecting rod and constantly moves to Compression and Expansion, and is easily generated fatigue crack in resilient sleeve,
Make resilient sleeve junk loss of seal；Furthermore resilient sleeve constantly rubs with hold-down ring endoporus at the volley, also can break because of abrasion
Split, carry out affecting service life, additionally, during connecting rod swings back and forth during drilling well, connecting rod also can be by retaining ring
Hinder, make connecting rod easily damage with retaining ring contact position, not only affect drilling progress, and a large amount of equipment can be wasted, make
Obtain drilling cost higher.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of simple in construction, and with low cost, hunting range is wide, service life
Long Universal coupling.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of Universal coupling, including
Joint, connecting rod, retaining ring, spheroid, pad and elastic sealing gasket, it is cylindric that described connecting rod is set to class, described connecting rod
Two ends end position be provided with sphere end, this sphere end stretches into inside joint, is matched therewith, described connecting rod sphere end end
Portion and sidewall locations are provided with ball-and-socket, and described spheroid is arranged in ball-and-socket, and described pad and elastic sealing gasket are set in turn in
Inside joint, described retaining ring is connected with joint by screw thread, compacting lock washer and elastic sealing gasket, this retaining ring bottom
Inwall is provided with groove, and described groove ends position is provided with annular projection, and described connecting rod is provided with bumper ring, described slow
Punching circle position is corresponding with annular projection position；In described connecting rod, parcel is provided with back-up coat.
Described spheroid is steel ball.
Described annular projection cross section is semicircle.
Described bumper ring caves inward towards center, annular projection side.
Described back-up coat is between the bumper ring of two ends.
The material of described elastic sealing gasket, annular projection and bumper ring is polyurethane or rubber.
Described back-up coat is steel layer.
Owing to using technique scheme, (1) connecting rod is provided with ball-and-socket near end, two ends and sidewall locations, described
Spheroid is arranged in ball-and-socket, makes the whole end of connecting rod be all connected by spheroid with joint interior grooves, moves more flexible；
(2) substituting original resilient sleeve with pad and elastic sealing gasket, its Intermediate gasket, in order to seal internal grease, is positioned at nipple orifice,
Elastic sealing gasket is between pad and retaining ring, during connecting rod swings back and forth, elastic sealing gasket will not produce tired
Labor crackle, thus the most easy to wear；(3) retaining ring bottom inwall is provided with groove, expands the swing space of connecting rod；Groove ends
Position installs and is equipped with annular projection, and described connecting rod is provided with bumper ring, described bumper ring position and annular projection position phase
Correspondence, and annular projection cross section is semicircle, bumper ring caves inward towards center, annular projection side, makes annular projection with slow
Just cooperating is enclosed in punching, during connecting rod swings back and forth, directly will not contact with retaining ring, cause abrasion, and
Being that bumper ring contacts with annular projection, it is to avoid abrasion, also increase hunting range while increasing the service life, activity is more
Nimbly and freely；(4), after hunting range increases, connecting rod stress strengthens, and is therefore enclosed with back-up coat in connecting rod, makes connecting rod
Firmer；(5) elastic sealing gasket, annular projection and bumper ring can be made with rubber, polyurethane etc., and materials are few and source is wide
General, simple in construction, it is easily worked, cost is relatively low.
The beneficial effects of the utility model are: have simple in construction, with low cost, hunting range is wide, service life length
Advantage.
