Abstract

A universal coupling comprises fork heads of driving and driven shafts, a cross shaft, a bearing, a circlip for hole and a pressing piece, wherein the pressing piece is connected with the fork heads by a bolt, and pressed on the outside of the circlip for hole, which brings the circlip for hole obvious quake-proof impact-proof effect, prevents the circlip for hole from the crack and shedding effectively, and prolongs the life span of the bearing, not influencing the use effect of the universal coupling.

Description

Hooks coupling universal coupling

Technical field

The utility model relates to a kind of integrated type jaw universal coupling with spider, belongs to mechanical transmission fields.

Background technique

Hooks coupling universal coupling is that a kind of permission two between centers have the mechanical transmission component than Angular Displacement, be widely used in automobile, boats and ships, mining machinery, papermaking equipment and metallurgical machinery, the location of cross axle step bearing in the transmission shaft jaw of prior art universal coupling with spider all adopts the hole to locate with back-up ring (abbreviation jump ring), coupling in use, the driving shaft of high speed rotating passes to driven shaft through cross axle with driving torque, because the angular displacement between the transmission shaft is bigger, the cross axle frequent swing forms huge impact load, impact force is passed to the transmission shaft jaw through bearing and jump ring, and jump ring is a kind of thin rubber-like fragility part, under powerful pulse load effect, very easily tired and burst apart or come off, and be difficult for discovering, cause damage of bearings and even whole coupling to be scrapped, cause the loss that stops production.

Summary of the invention

Technical problem to be solved in the utility model is to alleviate the impact of cross axle to jump ring, prolongs the working life of Hooks coupling universal coupling.

In order to solve the problems of the technologies described above the technical solution adopted in the utility model be: a kind of universal coupling with spider, comprise two transmission shaft jaws and cross axle, four axle heads of cross axle are hinged with two transmission shaft jaw holes respectively with the bearing supporting, and make bearing location with back-up ring and shaft end ring with the hole, a compressing member has all been installed with the back-up ring outside in described hole, and the seam face of this compressing member rides over the outside of hole with back-up ring.Described compressing member is a pressure ring or a gland.This compressing member connects with the transmission shaft jaw with screw.Used screw is the center with the jaw axis, is distributed in both sides symmetrically.

The utility model has the advantages that: 1, because compressing member is more abundant than jump ring, tightly be pressed on the jump ring, increased the rigidity of jump ring, have tangible antidetonation erosion control effect, limit jump ring effectively the moving of desired location, alleviated the impact that causes by the jump ring deformation displacement greatly.2, compressing member has guaranteed the nominal operating condition of bearing to the effective position-limiting action of jump ring, has increased the working life of bearing, has guaranteed cross axle when coupling running work, the compensate function of balance swing.3, the set screws of connection compressing member is that the center is symmetrically distributed in both sides with transmission shaft jaw axis, can strengthen the jaw hole effectively and up and down resist the ability of main impulsive load in the limit place, do not influence the diameter of transmission shaft again, reduce the radial dimension of driving mechanism as much as possible.The utility model Hooks coupling universal coupling uses through the test of last steel five factories, and the life-span has prolonged more than two times.

Embodiment

Fig. 1 is the utility model embodiment SWC type universal coupling with spider, and it mainly comprises initiative drive shaft jaw (1), screw (2), compressing member (3), cross axle (6), bearing (7), hole back-up ring (4), axle head ring washer (5) and driven transmission shaft jaw (8).Four axle heads of cross axle are hinged with driving and driven transmission shaft jaw hole respectively with the bearing supporting, bearing is located with back-up ring and shaft end ring with the hole, form complete Hooks coupling universal coupling, and with the outside of back-up ring a compressing member has been installed, be pressed in the hole tightly with outside the back-up ring in each hole, compressing member can be a pressure ring (as Fig. 2 and 3), also can be a gland (as Figure 4 and 5), the former radial dimension be less, and the latter then has seal action, can prevent that lubricant oil from leaking, and dustproof and waterproof.The mounting screw of compressing member is distributed in the jaw hole up and down near the limit, is the symmetrical distribution center line with the jaw axis, two limit places is born carry what ability to strengthen, and also can reduce radial dimension, dwindles the turning radius.

During work, the torque of initiative drive shaft by jaw aperture bearing and cross axle, reach the jaw hole of driven shaft, drive driven transmission shaft work, the angular displacement of transmission shaft is big more, the cross axle angle of oscillation is big more, and consequent impulsive load reaches the hole with back-up ring and compressing member through bearing, directly reaches jaw, make stable drive, can prolong the working life of Hooks coupling universal coupling again.
