Therefore, the gap between the spline pair is relatively large, and it is particularly easy to wear, resulting in a larger and larger gap
The increase of the gap will cause the coaxiality between the spline shaft in the middle and the spline bushing to increase, resulting in vibration and vibration of the coupling, and eventually lead to damage to the coupling and the bearings supporting its transmission

The invention is a cross-axle universal shaft coupling, belonging to the shaft coupling technical field, comprising spline shaft, spline shaft sleeve and joint cross, and characterized in that: the inner wall of the spline shaft sleeve is equipped with annular wearable sleeve and its advantages: because the wearable sleeve is uneasy to wear but easy to change, largely prolonging its service life, raising production efficiency and able to reduce vibration, making transmission stable and improving transmission accuracy.
Description
Technical field: [0001] The invention belongs to the technical field of shaft couplings, in particular to a cross-shaft universal joint. Background technique: [0002] At present, the cross-shaft universal coupling has been included in the national standard, and its structure is shown in Figure 1. However, since the cross-shaft universal coupling often rotates at high speed with a knuckle when it is used, among them The joint between the splined shaft and the splined sleeve will also continuously expand and contract while transmitting large torque. Therefore, the gap between the spline pair is relatively large, and it is particularly easy to wear, resulting in an increasing gap. The increase of the gap will cause the coaxiality of the spline shaft in the middle and the spline sleeve to become larger, which will cause the vibration and vibration of the coupling, and eventually cause damage to the coupling and the bearings supporting its transmission.
