1. Oil seal oil seal is a necessary barrier to protect bearings and smoothing agents from external pollution; during the working process of the bearing; no matter whether debris or moisture can enter the bearing; to prevent damage.
Proper device protection is an important factor in promoting the longest service life of bearings. Together; it is necessary to pay attention to the cleanliness of the bearings, the correctness of the bearing selection and the selection of appropriate devices and protections. Others; bearings need to avoid contamination And the pollution of moisture; and to ensure that the correct device and smooth. Therefore, the description of the bearing arrangement, the condition of the oil seal, the type of smoothing agent and the smooth cycle; even the special protection plays the same and important person.
2, the important factor in the selection of grease is the fault to select the grease, then all measures to prevent the bearing is also in vain; pick a grease; its base oil viscosity at the working temperature is able to supply the smooth effect is very important; viscosity is the first to be temperature The effect; it decreases with the rise of temperature; when the temperature decreases, it rises. Therefore; it is necessary to know the viscosity of the base oil at the working temperature. Mechanical manufacturers generally specify the use of certain oils; but most of the specifications are smooth The scale of fat application is very wide.
3, anti-rust function used in the bearing grease must have anti-rust effect; anti-rust agent is the best insoluble in water. Grease should have excellent adhesion; and can form a layer of oil film on the steel surface.
4, mechanical stability oil will become soft during machining; lead to leakage. During normal operation; grease will be smashed into the bearing from the bearing seat. If the mechanical stability of the grease is not working; during the work; the distribution of grease soap will occur Mechanical disintegration; the formation of grease is damaged; then the smoothing effect is lost.
5. The classification of oils is mainly based on the difference between temperature and working conditions: oils can be classified according to their allowable working temperature; the consistency and smoothness of oils are affected by working temperature; bearings that operate at a certain temperature need to be selected. Grease with the correct consistency and outstanding smoothing effect at the same temperature. Grease is made at a different working temperature scale; roughly distinguishable from low temperature, medium temperature and high temperature grease. Together; one type of grease is called resistant Kneading or kneading and adding molybdenum disulfide; together; adding an increase agent to strengthen the strength of the smooth oil film.
6, mixed grease should never mix incompatible oil; if it is mixed with two incompatible oils; generally its consistency will become soft; in the end may be due to the simple loss of grease to form bearing damage. If you do not know the original bearing Which kind of smooth grease is used; it is necessary to completely remove the old grease in the bearing table before adding new grease.
The following are some important factors in the selection of smooth grease: mechanical varieties, bearing varieties and large. Also ぷ魑 龋ぷ鞲 龋ぷ鞲 汕榭觯俣 汕榭觯俣 ぷ髑榭觯蝗缯穸 ぷ髑榭觯蝗缯穸 ぷ髑榭觯蝗缯穸 ぷ髑榭觯蝗缯穸 ぷ髑榭觯蝗缯穸 ぷ髑榭觯蝗缯穸 ぷ髑榭觯蝗缯穸 ぷ髑榭觯蝗缯穸 ぷ髑榭觯蝗缯穸 ぷ髑榭觯蝗缯穸Weird 淙 淙 榭觯芊庑Ч馕Щ ..
