Embodiment Construction

[0021] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0022] In the embodiment of the present invention, the universal joint of the square bar ball universal coupling is composed of ball joint 1, square joint 6, split ball seat 3, ball joint square bar 4 and center positioning assembly 8 and other main components. Composition, such as figure 1 shown. The ball head of the ball head square rod 4 can rotate freely in the split ball seat 3, which forms a hinge point, and the square rod of the ball head square rod 4 can move along the center of the square hole in the square hole of the square head receiver 6. The wire can move in a straight line and can rotate in a small angle (only a small angle), which can ensure the flexibility of the joint.

[0023] The ball seat of the square rod ball universal coupling joint is split type, which is composed of two split ball seats 3 and a snap ring 2. The split ball seat 3 i...

Abstract

The invention discloses a square bar ball universal shaft coupler. The square bar ball universal shaft coupler is equipped with a universal joint which consists of main parts such as a ball head catcher, a square head catcher, a split type ball base, a ball head square bar and a central positioning assembly, wherein the split type ball base and the ball head square bar define a force transmissionhinge pair; the ball head square bar and a square hole of the square head catcher define a force transmission planar pair; the positions, on opposite two side surfaces, of the square bar of the ball head square bar are provided with bulged circular arcs for meeting universal requirements of the joint; the split type ball base meets compactness, rationality and manufacturing feasibility of the structure; and the central positioning assembly meets, stability, in an operation process, of the joint. The square bar ball universal shaft coupler has the characteristics of being compact and reasonablein structure, great in bearing ability, good in manufacturing maintenance, good in balance stability and the like, is suitable for heavy load, and is also suitable for high-speed light load.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a square bar-ball universal coupling. Background technique [0002] The existing universal joints have the defect of short service life when they are used in transmissions with large loads and impacts. In addition, the existing universal joints have poor maintenance performance. Once a failure occurs, the entire joint will be destroyed. To be scrapped or even the whole coupling will be scrapped. Contents of the invention [0003] In order to solve the structural defects and poor maintenance performance of the existing universal joints in the background technology, the present invention provides a universal joint with a simpler and more reasonable structure. [0004] The technical solution adopted by the present invention to solve the technical problem is: a square bar-ball universal joint, which is provided with a universal joint, including a ball joint and a square joint, and the connectio...
