Can the butter lubricate the cardan shaft?

Generally speaking, the fluidity of butter at room temperature is very poor and the needle can only be rotated in place during work. When the original oil film fails, it is difficult to form a new oil film, which leads to a semi-dry friction or dry friction state of the cardan shaft, then can the filling of butter play a lubricating role for the cardan shaft?

Can the butter lubricate the cardan shaft?

Due to the poor tenacity of the oil film and the cardam shaft in the work to bear large torque and alternating load, it is difficult to form a good oil film in the bearing. Therefore, the lubrication of the cardan shaft can not use butter but should be filled with gear oil.

The cardan shaft is subjected to large torque and alternating load in the work, and the damage form is mainly the wear of the cardan shaft journal and needle roller bearing.

However, in the actual work, because the cardan shaft oil nozzle is the same as the butter nozzle, sometimes for easy operation and sometimes for no filling equipment, many drivers and warranty personnel mistakenly think that the cardan shaft needle roller can be lubricated with butter, which will cause early damage to the cardan shaft.
