In order to make the vertical vibration motor have a long service life, the maintenance of bearing is the key, and the daily lubrication is the key. Today I will discuss in detail the grease used in vertical vibration motors.

Grease for vertical vibration motors can be generally divided into two categories:

1、 Lithium grease

Lithium base grease is made of fatty acid lithium soap thickened by medium viscosity mineral oil or synthetic oil, while synthetic lithium grease is made from synthetic fatty acid lithium soap thickened by medium viscosity mineral oil. Lithium grease has a high working temperature. It can be used for a long time at 120 ° C and for a short time at 150 ° C. Compared with other greases, it has the advantages of less consumption, longer service life and wide application range. It includes three types of automotive general lithium grease, extreme pressure lithium grease and general lithium base grease. Commonly used in automobiles and tractors is automotive lithium grease, which is suitable for lubricating friction parts such as automotive hub bearings, chassis, water pumps and generators at 30-120 ° C.

2、 Calcium based grease

Calcium based grease is often referred to as "butter.". Calcium grease is prepared by thickening medium viscosity mineral oil with natural fatty acid calcium soap, and synthetic calcium grease is prepared by thickening medium viscosity mineral oil with synthetic fatty acid calcium soap. It has the advantages of good water resistance, good mechanical stability, easy pumping and low price, but it also has the disadvantages of low temperature and short life. According to the penetration (penetration) of the working cone, calcium based grease is divided into four grades: 1, 2, 3 and 4. The working temperature of No.1 and No.2 is not higher than 55 ℃, and that of No.3 and No.4 is not higher than 60 ℃. At present, No. 1 and No. 2 grease are often used, while No. 3 and No. 4 grease are used for high load and low speed equipment.

Our company's vertical vibration motor bearing lubrication is generally shell 3 ා lithium grease, the filling amount depends on various specifications. There are detailed instructions in the instruction manual. If you have higher requirements, you can contact us for adjustment.
