Embodiment Construction

[0021] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] like figure 1 Shown is a schematic structural diagram of an embodiment of the connector of the present invention. The connector 1 of this embodiment is in the shape of a ring, and the connector 1 is provided with four ear holes 2 evenly distributed in a ring, the axes of the two opposite ear holes 2 coincide and are located in the radial direction, and the two axes of the four ear holes 2 are in the on the same plane and perpendicular to each other.

[0023] By setting the connector 2 in a ring shape, the force applied to the connector when the universal joint rotates is also located in the circumferential direction, thereby avoiding stress concentration and enhancing the force bearing performance of the connector 1 .

[0024] like figure 2 Shown is a schematic structural view of a fork head embodiment of the present ...

Abstract

The invention discloses a ring type earhole universal joint, which comprises a connector which is of a ring shape and two jaws which consist of a rotary shaft and a support shaft and are Y-shaped; four earholes are arranged on the connector; and axes of two opposite earholes are overlapped; two axes of the four earholes are in teh same plane and vertical to each other; the rotary shaft and the support shaft are fixedly connected or integrally molded; a connecting structure used for being connected with other shafts is arranged on the rotary shaft; two shaft heads which are in rotational matching with the two opposite earholes are arranged at two ends of the support shaft; and the two jaws are respectively installed at two sides of the connector. The ring type earhole universal joint provided by the invention can effectively overcomes defects in stress concentration of the existing universal joint pin and has simple structure and better stress performance. The invention also discloses the connector and the jaws, which are arranged on the ring type earhole cardan and are coordinately used.

Description

technical field [0001] The invention relates to a universal joint, in particular to a ring-type earhole universal joint and a connector and a fork used for the ring-type earhole universal joint. Background technique [0002] The existing cross shaft universal joint is composed of two forks and a cross shaft. The cross shaft is provided with four cross-shaped shaft heads, and two plugs are respectively rotatably fitted on the two opposite shaft heads. Because there is a structural mutation on the journal of the fork head of the existing cross shaft universal joint, a large stress concentration will be generated during the transmission process, and there is also a structural gap at the junction of two adjacent shaft heads of the cross shaft. mutation, there is also stress concentration in the transmission process. [0003] The Chinese patent with the publication number CN 202144842U discloses a cross shaft universal joint, which includes an intermediate shaft body, an axial a...
