The advantages of rolling bearings using smooth oil smooth are:
1) It can ensure that the higher operating temperature is reached.
2) The bearing in the reduction gearbox is very suitable when smooth oil is smooth; because the oil together with the splash method reaches the intention of smooth gears and bearings together.
3) In the bearing, the smooth grease is gradually contaminated by the product wear product, the abrasive, the product which is saturated from the outside through the sealing device and the self-aging product; if not exchanged in time, the bearing is accelerated to wear; and when the liquid smoothing agent is used; Filter to make sure it works.
4) When changing the fat; it is necessary to disassemble the relevant connecting parts; when the oil is smooth; there is no such trouble.
5) Under certain operating specifications; the smoothing of the starting torque and the loss of collision with smooth grease is significantly smaller than smooth grease.
6) Because the smooth oil takes away the heat in the circulation to cool the effect; it can make the bearing reach a relatively high transition speed.
The smooth bearing strength of rolling bearings:
1) The grease itself has a sealing effect; this allows the use of a tissue with a low degree of sealing to achieve a simplified depiction.
2) Experience has proved that in the range of certain speed (n < 20000 r / min or dn < 20000 mm. r / min) with lithium grease smoother than the drop method has a lower temperature rise and longer bearing life.
3) Single bearing point; always need to add oil by hand; if you use grease, it will save energy and prevent the formation of trouble due to lack of oil.
2, rolling bearing failure type and smooth contact: most of the failure is due to the installation of wool. 芊ç 涣 grade 鸹 鸹 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . , corrosion and overheating, etc.
3, the basic characteristics of smooth grease and the general specification for the selection of smooth grease:
When selecting smooth grease; it is necessary to select smooth greases that are compatible with the application conditions (temperature, speed, load, environment, etc.); these are related to the fundamental properties of smooth grease; and the fundamental properties of smooth grease depend on thickeners and foundations. Variety of oil.
