Our company is committed to the R & D and innovation of transmission shaft hanger, and has established a good supporting cooperation relationship with many automobile manufacturers. The following Xiaobian brings you information about the selection of the base plane of the transmission shaft hanger.
 
1. Selection of coarse datum. For general support parts, it is completely reasonable to take the relative surface of the support bottom as the rough datum. However, for this part, if the relative surface of the support bottom is used as the rough datum, the surface datum may not be guaranteed. Therefore, according to the selection principle of the rough datum (that is, if the part has unprocessed surfaces, these unprocessed surfaces should be used as the rough datum; if the part has several unprocessed surfaces, the unprocessed surfaces with high relative positional accuracy required to the machined surfaces should be used as the rough datum).
