Internal loss of lubrication energy of silent antirust bearing in shower room
The bearing structure and accuracy also have certain influence on the selection of lubricating grease. The smaller the silent antirust bearing in shower room effective space or clearance inside the bearing, the higher the machining accuracy of the working surface, and the lower the viscosity of the base oil that can be selected, which can reduce unnecessary energy loss and improve the fluidity of the grease.
When the working surface is rough, the viscosity of the base oil shall be increased. At this time, because the contact surface is in local contact, the pressure at the contact part is large and it is not easy to form an oil film.
Under wet or wet working conditions, calcium base grease should be the first choice because it is not easily soluble in water, while sodium base grease, which is easily soluble in water, should be used under dry and low moisture conditions.
When selecting grease, the following points should also be noted:
Under general speed and load temperature, the minimum kinematic viscosity of various bearings shall not be less than 15mm2/s
The dropping point of the selected grease must be 20 ~ 30 ℃ higher than the operating temperature to ensure the lubrication effect
Due to its poor fluidity, high friction resistance and low thermal conductivity, grease should not be used as a circulating lubricant. If it must be silent antirust bearing in shower room used for centralized grease supply, the grease with large penetration shall be selected.
