Embodiment Construction

[0011] See attached figure 1 , figure 2 , a new tripod lever sliding universal joint, including: input shaft disk (1), sliding rod (2), tripod lever output shaft (3), end cover (4), sliding ball (5), The input shaft disc (1) has a structure in which the left side is a cylinder and the right side is a disc. The left side of the input shaft disc (1) is processed with a keyway at one end of the cylinder, and the right side disc is evenly distributed with three An elliptical sliding hole, and the direction of the major axis of the ellipse of the elliptical sliding hole is the same as the radial direction of the disc on the right side of the input shaft disc (1), the sliding rod (2) is an elliptical cylinder on one side, and It is a V-shaped slideway structure, and two threaded blind holes are symmetrically processed on the outside of the right end of the V-shaped slideway. There are three sliding rods (2), and the three sliding rods (2) are connected to the input shaft disc ( 1...

Abstract

The invention relates to a novel three-fork-rod sliding type universal coupling which comprises an input shaft disc, sliding rods, a three-fork-rod output shaft, end covers and sliding balls, whereinthree sliding rods are arranged in three oval sliding holes of the input shaft disc in a matched way at an 120-degree angle; the three sliding balls are arranged in V-shaped slideways of the three sliding rods; three fork rods of the three-fork-rod output shaft is respectively matched with sliding holes of the three sliding balls; and the three end covers are respectively arranged at the outer sides of the V-shaped slideways of the three sliding rods through screw bolts. Through relative sliding between the input shaft disc and the sliding rods, between the V-shaped slideways of the sliding rods and the sliding walls, and between the sliding holes of the sliding balls and the three fork rods of the three-fork-rod output shaft, the universal transmission of the coupling is realized. The novel three-fork-rod sliding type universal coupling has the beneficial effects that the structure is simple; the bearing capability is high; and the lubrication is easy.

Description

[0001] Technical field [0002] The invention relates to a mechanical transmission device, in particular to a novel tripod lever sliding type universal joint. Background technique [0003] The universal coupling makes use of the characteristics of its mechanism to make the two shafts not on the same axis, and when there is an angle between the axes, it can realize the continuous rotation of the connected two shafts, and reliably transmit torque and motion. There are cross shaft, There are many structural types such as ball cage type, ball hinge plunger type, and tripod sliding type. Compared with other structures, the tripod sliding type universal coupling was born late, so many structures are still in continuous improvement. . The cross-section of the sliding part of the traditional trigeminal sliding type universal joint is circular, and the bearing capacity is weak. In order to realize the universal transmission, the joint bearing is used to realize the angle compensation,...
