The low price of PM type stepping motors is one of its major advantages. The air gap between the stator and the rotor is about 0.25mm, and the bearing uses sliding bearings.
HB type stepping motors generally use rolling bearings, the inner ring of the bearing is closely matched with the shaft, and the outer ring is slidingly matched with the stator. The axial pre-tightening force between the inner and outer rings must be generated by the bearing spring.
According to the precision requirements of the stepping motor, different bearing grades will be considered. Rolling bearing grease is selected according to its use temperature range.
Adding grease to the bearings in the motor plays a very important role. However, is it possible to use grease to lubricate the bearing indefinitely? When should the grease be changed and how much should it be changed?
As to whether grease can be used indefinitely, the affirmative answer is no. Because too much grease will cause a lot of harm to the bearing.
Appropriate grease has a good effect on the bearing, and it has good adhesion, wear resistance, temperature resistance, rust resistance and lubricity.
Baoxing has specially developed a series of bearing grease BX-280 series, BX-300/A series, BX-800 series and other products for motor bearings.
It can effectively resist oxidation, delay aging, dissolve carbon deposits, prevent the accumulation of metal wear debris and oil stains, and improve mechanical wear resistance, pressure resistance and corrosion resistance.
15 years of focusing on the research and development of various bearing anti-wear lubricants and greases.
