Abstract
The utility model relates to a cardon joint assembly with counter bores. The cardan joint assembly comprises a cross shaft. A shaft head is respectively arranged on the cross shaft in the cross direction, a shaft sleeve is sleeved outside each shaft head, the shaft sleeves are connected with the shaft heads through bearings, first counter bores are formed in the shaft heads in the radial direction, second counter bores are formed in the bottom portions of the bearings, nylon gaskets are arranged inside the second counter bores, and the shaft heads are connected with the bearings in a matching mode through the nylon gaskets. The shaft heads of the cross shaft are matched with the bearings through the nylon gaskets, and therefore the assembling precision of a cardan joint is improved and the assembling of a universal coupling is convenient. The design of the counter bores of the shaft heads of the cross shaft increases the storage amount of lubricating grease, and prolongs the service life of the cardan joint.
Description
Technical field
The utility model relates to a kind of universal joint assembly, especially relates to a kind of universal joint assembly that has counterbore.
Background technique
Universal joint refers to and utilizes device such as ball-type realizing the axle power output of different direction, and it also is on the automobile one very vitals.Universal joint and transmission shaft combination are called card gear.On the vehicle of front-mounted engine rear wheel drive, card gear is installed between transmission output shaft and the ransaxle main reducing gear input shaft; And the vehicle of front-mounted engine front-wheel drive has omitted transmission shaft, and universal joint is installed between not only responsible driving but also the propons semiaxis of being responsible for turning to and the wheel.
In universal joint cooperated, component (output shaft) were to be driven by the rotation of another component (input shaft) around it around the rotation of self axle.On torsional direction, whether there is tangible elasticity can be divided into rigid universal joint and flexible universal joint by universal joint.The rigidity universal joint can be divided into three kinds of nonconstant velocity universal joint (commonly used for Cardon universal joint), near constant velocity universal joint (as the twin universal joint) and constant velocity universal joints (as rzeppa universal joint) again.The big model universal joint assembly of present domestic engineering machinery also rests on the seventies technical standard.Domestic big model universal joint assembly is subject to equipment processing ability and technology at that time, generally all controlling length with back-up ring, universal joint assembly length by the mill back-up ring with the cross axle shoulder, cause cross axle and bearing bottom gapped, influence the performance of universal joint, and reduced its working life.
The model utility content
In order to overcome the deficiency that prior art exists, the utility model provides a kind of universal joint assembly that has counterbore.
A kind of universal joint assembly that has counterbore, comprise cross axle, be respectively equipped with spindle nose on the cross direction of described cross axle, described spindle nose is arranged with axle sleeve outward, be connected by bearing between described axle sleeve and the spindle nose, radially be provided with first counterbore on the described spindle nose, described bearing bottom is provided with second counterbore, be provided with nylon spacer in described second counterbore, be connected by nylon spacer between described spindle nose and the bearing.
Preferably, seal mutually by oil sealing between the afterbody of described axle sleeve and the spindle nose.
Preferably, described first counterbore is arranged on the central position of spindle nose.
The spindle nose of the utility model cross axle and bearing adopt nylon spacer to cooperate, and have improved the universal joint assembly precision, have made things convenient for the Hooks coupling universal coupling assembling; The counterbore of cross axle spindle nose designs, and has increased the storage volume of lubricating grease, prolongs the working life of universal joint.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view of A portion among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, Fig. 2, a kind of universal joint assembly that has counterbore, comprise cross axle 1, be respectively equipped with spindle nose 2 on the cross direction of described cross axle 1, be connected by bearing 8 between the described spindle nose 2 outer axle sleeves 3 that are arranged with, described axle sleeve 3 and spindle nose 2, radially be provided with first counterbore 4 on the described spindle nose 2, described first counterbore 4 is arranged on the central position of spindle nose 2.
Described bearing 8 bottoms are provided with second counterbore 5, are provided with nylon spacer in described second counterbore 5, are connected by nylon spacer 6 between described spindle nose 2 and the bearing 8.Seal mutually by oil sealing 7 between the afterbody of described axle sleeve 3 and the spindle nose 2.
