A cross universal coupling

Abstract

The invention relates to the field of shaft couplings, in particular to a cross cardan coupling, comprising a spline shaft, a spline sleeve is sheathed on the right side of the spline shaft, and a spline sleeve is provided on the left side of the spline sleeve. A locking mechanism is fixedly welded, and the locking mechanism is sleeved on the outer surface of the spline shaft. The right end of the spline sleeve is fixedly connected with a first flange, and the first flange passes through the first lock. Tight bolts are fixedly connected with a second flange. The invention can effectively reduce the friction between the spline shaft and the spline sleeve through the locking mechanism, slow down the degree of wear, and further improve the service life of the spline pair, and then through the first shock pad and the second shock absorber in the buffer mechanism The shock pad can buffer and weaken the axial impact force on the cross universal coupling, reducing its damage. At the same time, the protection mechanism has a good protection effect on the first cross shaft body and the second cross shaft body, greatly The service life of the cross universal coupling is improved.

Description

technical field [0001] The invention relates to the field of shaft couplings, in particular to a cross universal coupling. Background technique [0002] The universal coupling utilizes 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. The characteristics are: its structure has a large angular compensation capability, compact structure, and high transmission efficiency. Different structural types of universal couplings have different angles between the two axes, generally between 5°-45°.

Problems solved by technology

[0003] At present, cross universal couplings are widely used in various production equipment and products. In the use of cross universal couplings, due to the relative axial movement between the spline shaft and the spline sleeve, the spline The shaft and the spline sleeve will rub against each other, which will accelerate the wear of the spline pair and greatly reduce its service life. The impact on each component will accelerate the damage of the cross universal coupling. At the same time, due to the inertia, the cross shaft is often subject to additional loads, causing it to be easily deformed and damaged. Therefore, a cross universal coupling is proposed to solve the above problems. question
