Abstract
The utility model relates to a cross axle universal joint, in particular to a maintenance-free cross axle universal joint. The maintenance-free cross axle universal joint comprises a cross axle (1), a roller pin (2) and a bearing sleeve (3); the roller pin (2) is arranged on the periphery of the head of the cross axle (1); the head of the cross axle (1) is arranged in the bearing sleeve (3) through the roller pin (2); a grease seal (4) is arranged between the cross axle (1) and the bearing sleeve (3); a dustproof cover (5) is arranged at an opening end of the bearing sleeve (3); the dustproof cover (5) is in a bowl shape; the bowl-shaped dust cover (5) is inversely buckled at the opening end of the bearing sleeve (3); and a grease storage cavity (9) is formed on the end surface of the head of the cross axle (1). The maintenance-free cross axle universal joint can be closely matched with the excircle of the cross axle so as to ensure that grease is not leaked, and prevent dirt, such as external sediment and the like, from entering the inner part of a bearing, has better sealing performance, is maintenance-free, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of Hooke's joint, specifically relates to a kind of non-maintaining Hooke's joint.
Background technique
Hooke's joint is mainly used in the transmission of power of varied angle; Be widely used in fields such as automobile or textile manufacturing machine; It comprises cross axle 1, needle roller 2 and bearing housing 3 (like Fig. 1 ~ shown in Figure 3), and it is peripheral that needle roller 2 is arranged at the spindle nose of cross axle 1, and the spindle nose of cross axle 1 is arranged in the bearing housing 3 through needle roller 2; Seal with oil sealing 4 between the spindle nose of cross axle 1 and the bearing housing 3, and dust-proof cover 5.The dust-proof cover of existing Hooke's joint adopts nylon to process, because the restriction of nylon material extension property, outside muddy water more or less can get into bearing; Dilution lubricating grease influence lubrication effect, reduction bearing working life; And the inner cross oil duct for connecting of the cross axle of existing structure, link to each other with outside grease nipple, so the cross axle internal and external pressure balance; Oil sealing is in free state, and its sealability is relatively poor, and internal grease can be revealed; Outside foreign material can get into, and therefore need uninterrupted the maintenance to replenish new grease.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and the non-maintaining Hooke's joint of a kind of good seal performance, long service life is provided.
The purpose of the utility model is achieved in that a kind of non-maintaining Hooke's joint; It comprises cross axle, needle roller and bearing housing; It is peripheral that said needle roller is arranged at the cross axle spindle nose, and the spindle nose of cross axle is arranged in the bearing housing through needle roller, is provided with oil sealing between said cross axle and the bearing housing; Said cage openings end is provided with dust-proof cover; Be characterized in: said dust-proof cover is a bowl type, and the dust-proof cover back-off of said bowl type all offers shoe cream room in the cage openings end on the spindle nose end face of said cross axle.
Said dust-proof cover adopts hydrogenated nitrile-butadiene rubber to process, and is equipped with skeleton I in the said dust-proof cover.
Said oil sealing adopts hydrogenated nitrile-butadiene rubber to process, and said oil sealing periphery is coated with skeleton II.
Compared with prior art, the beneficial effect of the utility model is:
A kind of non-maintaining Hooke's joint of the utility model, its dust-proof cover are bowl type back-off in the cage openings end, and dust-proof cover adopts hydrogenated nitrile-butadiene rubber to process; And four spindle noses of cross axle are separate, all offer shoe cream room on the spindle nose end face, after cross axle and the needle bearing assembling; Gap in shoe cream room and the needle bearing is filled up by grease, and air is discharged, and forms a negative cavity; Dust-proof cover wraps tightly on the bearing housing end face under action of air pressure, and can closely cooperate with the cylindrical and the end face of cross axle, can guarantee that grease do not reveal; Prevent dirt entering bearing inside such as outside silt; Its sealability is better, makes Hooke's joint avoid safeguarding, has improved its working life.
