Description

Technical Field

[0001] The utility model relates to the technical field of yokes, in particular to an open yoke seat. Background Art

[0002] The yoke is an indispensable component of the universal joint. Nowadays, the yoke can be divided into locking yoke, welding yoke, riveted yoke and telescopic yoke, among which the locking yoke is a commonly used universal joint yoke. The traditional structure of the locking yoke consists of a U-shaped cross-shaft connector and a connecting part arranged at the end of the cross-shaft connector for connecting the drive shaft. Since there is no limiting structure on the cross-shaft connector and the connecting part, the drive shaft can easily collide with the cross-shaft during installation, which affects the assembly accuracy at the cross-shaft and may even damage the cross-shaft. In addition, the structural strength of the U-shaped cross-shaft connector is relatively low. Utility Model Content

[0003] The purpose of the utility model is to provide an open yoke seat, which can improve the mechanical strength of the yoke body through reinforcing ribs, and at the same time prevent the transmission shaft from colliding with the cross shaft during installation, and prevent the reinforcing ribs from being damaged during installation of the transmission shaft through springs and limiting plates.

[0004] In order to achieve the above-mentioned purpose, an open yoke seat is provided, including a yoke body, a reinforcing rib is fixedly connected to the inside of the yoke body, a plurality of springs are fixedly connected to the lower end of the reinforcing rib, a limiting plate is fixedly connected to the lower end of the spring, an oil storage tank is provided inside the reinforcing rib, oil outlet channels are provided on both sides of the oil storage tank, oil outlet holes are symmetrically provided inside the yoke body, and an oil filling channel is provided on one side of the oil storage tank.

[0005] According to the open yoke seat, mounting holes are provided on both sides of the yoke body.

[0006] According to the open yoke seat, a spline shaft hole is formed at the lower end of the yoke body.

[0007] According to the open yoke seat, the oil outlet hole is connected to the oil outlet channel.

[0008] According to the open yoke seat, a sealing cover is provided inside the oil injection channel.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. This open yoke seat improves the mechanical strength of the yoke body by setting reinforcing ribs, and can prevent the transmission shaft from colliding with the cross shaft during installation. The spring and the limiting plate prevent the transmission shaft from causing damage to the reinforcing ribs during installation.

[0011] 2. The open yoke seat is provided with an oil storage tank, an oil outlet channel and an oil outlet hole to achieve lubrication and ensure transmission effect.

[0012] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
