What are the factors that cause the journal and bearing wear of the cross-shaft universal coupling?

Many friends of the cross shaft universal coupling journal and bearing wear is quite a headache! So how should we minimize the journal and bearing wear of the cross-shaft universal coupling? Let's take a look at it!
The cross shaft of the universal coupling is also called ten bytes, which is a mechanical part to achieve variable Angle power transmission and is used to change the position of the transmission axis. In the transmission process, the failure of the cross-shaft universal coupling is mainly due to the excessive wear of the journal of the cross-shaft and the bearing, and the bending deformation of the journal, resulting in the center line of each shaft of the cross-shaft is not in the same plane, or the center line of the adjacent two axes is not vertical.
Because the wear gap between the journal and the bearing of the cross-shaft universal coupling is too large, the cross-shaft wobbles during operation, resulting in the shaft center line deviating from the rotating center line. In the process of operation, the coupling will appear abnormal sound phenomenon. The main cause of wear is lack of lubrication. If the wear is too deep, it will need to be surfacing and bushing repair in the journal and bearing. Heat treatment and grinding are also performed. After repair, the perpendicality of the two adjacent axes should be vertical, and the axes are in the same plane.
These are several factors that we bring to you about the journal and bearing wear of the cross-shaft universal coupling, hoping to help you friends.
