Can butter be used as lubricating oil for the cardan shaft?

For the use of the cardan shaft, it is necessary to regularly fill the lubricating oil, but some people are more confused, that butter can also be used as lubricating oil on the cardan shaft? Today, let's see if butter can be used as cardan grease.

Can butter be used as lubricating oil for the cardan shaft?

Generally speaking, the composition of butter is composed of thickening agent calcium and basic lubricating oil, and its structure is relatively dispersed. If it continues to operate for a long time under a large load, most of the lubricating oil in the oil film will be separated, and the oil film is basically non-existent. 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, resulting in semi-dry friction or dry friction of the cardan shaft. Because the toughness of the butter film is poor, and the cardam shaft has to withstand large torque and alternating load in the work, it is difficult to form a good oil film in the bearing.

Cardan shaft is subjected to large torque and alternating load in the work, and its damage form is mainly the wear of cardan shaft journal and needle roller bearing. In actual work, because the cardan shaft oil nozzle is the same as the butter nozzle, many drivers and warranty personnel mistakenly use butter on the cardan shaft needle roller, resulting in early damage to the cardan shaft.
