Abstract
The utility model relates to a bearing of ability rotation comprises outer ball, kingpin, interior ball, circlip, the inner wall both sides processing of outer ball slotted, inslot that interior ball is packed into and process in outer ball, the inner wall that should outer ball and the outer wall of interior ball form a closed interval, the kingpin be in in this closed interval, intermural card is equipped with circlip in ball outside bottom surface and the outer ball in this, and three round pin chord positions are on interior ball inner wall and circlip, the spherical outside surface design of outer ball become to put in order globular, it adopts big profiteer's horn shape with upper and lower planar junction, the beneficial effects of the utility model are that: ectosphere flange in bearing adopts can improve the life that the universal joint is sold to three balls.
Description
Technical field
This utility model belongs to needle bearing technical field, particularly relates to the needle bearing of a kind of energy rotation.
Background technology
Tripod universal joint is made up of spider 1, needle roller 2, ball 3, needle roller back-up ring 4, elastic spring 5.Specific product structure and features is shown in Fig. 1.Needle roller 2 is between spider 1 journal surface and ball 3 Internal Spherical Surface, for preventing needle roller 2 from coming off, adopts needle roller back-up ring 4 and elastic spring 5 to block.Have a disadvantage in that:
1, after tripod universal joint assembling, needle roller 2 has partial denudation outside, affects its motility during rotation；
2, needle roller 2 in ball 3 with spider 1 can longitudinally-moving, the shaft shoulder and needle roller back-up ring 4 mainly by spider 1 block, and owing to needle roller back-up ring 4 is stamping parts and relatively thin, under the friction of needle roller 2, easy initial failure, causes ball 3 and needle roller 2 to come off；
3, owing to spider 1 axle journal jump-ring slot is little, elasticity and hardness requirement to elastic spring 5 are higher, cause initial failure example more because elastic spring 5 comes off.
Summary of the invention
The purpose of this utility model is in that the deficiency overcoming prior art to exist, and provide a kind of avoid because of the abrasion of needle roller back-up ring and elastic spring come off cause initial failure situation can the needle bearing of rotation.
The purpose of this utility model completes by following technical solution, it is made up of outer ball, needle roller, interior ball, circlip, the inwall both sides processing of described outer ball has groove, interior ball loads in the groove that outer ball is machined, forming a closed interval between the inwall of this outer ball and the outer wall of interior ball, described needle roller is in this closed interval；Being arranged with circlip between the inwall of this interior ball outside bottom surface and outer ball, spider is positioned on ball inwall and circlip.
As preferably, the spherical outside surface of described outer ball is designed to whole spherical, and its junction with lower planes adopts big chamfering shape.
The beneficial effects of the utility model are: newly-designed structure need to be avoided because the abrasion of needle roller back-up ring and elastic spring come off and cause the situation of initial failure, and the design after change still has rotation, feature flexibly of sliding, and can improve the service life of tripod universal joint.
Accompanying drawing explanation
Fig. 1 is existing tripod universal joint structural representation.
Fig. 2 is tripod universal joint structural representation of the present utility model.
Fig. 3 is needle bearing structural representation of the present utility model.
Label in accompanying drawing is respectively as follows: 1, spider；2, needle roller；3, ball；4, needle roller back-up ring；5, elastic spring；6, outer ball；7, interior ball；8, circlip；9, closed interval；61, groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model done detailed introduction: as shown in accompanying drawing 2,3, this utility model is made up of outer ball 6, needle roller 2, interior ball 7, circlip 8, the inwall both sides processing of described outer ball 6 has groove 61, interior ball 7 loads in the groove 61 that outer ball 6 is machined, forming a closed interval 9 between the inwall of this outer ball 6 and the outer wall of interior ball 7, described needle roller 2 is in this closed interval 9；Being arranged with circlip 8 between the inwall of this interior ball 7 outside bottom surface and outer ball 6, this circlip 8 can prevent interior ball 7 from coming off；Spider 1 is positioned on ball 7 inwall and circlip 8.The innovative point of this structure is in that: due to the equal rib of inside and outside ball, needle roller is in closed state, and product is integrated, and will not fall apart；Inside and outside ball case hardness is consistent with needle roller hardness, will not produce a certain part premature wear because of stiffness issue.
The spherical outside surface of described outer ball 6 is designed to whole spherical, and its junction with lower planes adopts big chamfering shape；Its object is to: outer ball is whole ball, and Curvature varying is little, spherical outside surface adopts big chamfering so that it is rotate more flexible.
This utility model is not limited to above-mentioned embodiment, no matter making any change, every employing structural design provided by the utility model on its shape or material are constituted, being all a kind of deformation of the present utility model, being all considered as within this utility model protection domain.
Claims (2)
1. the needle bearing of energy rotation, it is made up of outer ball (6), needle roller (2), interior ball (7), circlip (8), it is characterized in that: the inwall both sides processing of described outer ball (6) has groove (61), interior ball (7) loads in the groove (61) that outer ball (6) is machined, forming a closed interval (9) between the inwall of this outer ball (6) and the outer wall of interior ball (7), described needle roller (2) is in this closed interval (9)；Being arranged with circlip (8) between the inwall of this interior ball (7) outside bottom surface and outer ball (6), spider (1) is positioned on ball (7) inwall and circlip (8).
2. according to claim 1 can the needle bearing of rotation, it is characterised in that: the spherical outside surface of described outer ball (6) is designed to whole spherical, and its junction with lower planes adopts big chamfering shape.
