Pay is basically in the rolling friction (ball bearing), or mainly in rolling friction with sliding friction (roller bearing) friction in the bearings; In addition, the vast majority of grease in the bearings in a quiescent state, through the oil separator and the flow of a small amount of grease to the lubrication points added new grease. 2 # and 3 # consistency of the grease in the bearing in most cases the formation of the state of the channel flow is conducive to bearing seal and lower bearing temperature rise, while too large, the adhesion will increase the bearing temperature and power consumption is not conducive to bearing lubrication.
According to the size of the coupling axis deflection, friction to pay operating status can be divided into two cases: when the axis of deflection, basically in sliding friction; the axis of deflection is small, in a typical micro- Fretting wear state. The same time, the grease and the coupling with the rotation, the grease must not only resist the great centrifugal force, and the delivery role of the centrifugal force or coupling added grease. Therefore, adhesion and smaller sub-oil of the grease to resist the centrifugal force in the coupling, avoid grease oil soap separation and thrown from the coupling, that is, only attached to the surface of the grease in the friction to pay to play a role in lubrication. 0 # 1 # consistency of grease due to better mobility, in most cases is more suitable for use in the coupling.
Under normal circumstances, especially in the steel industry, foreign mostly recommended to use a special grease, but the general domestic use alternatives, coupling failure is frequent, relatively short life.
To this end, Beijing En Oukai lubrication seal technology Co., Ltd., from Italy VISCOL, the introduction of the Molyvis HDP-specific fat, the product is a lithium complex thickener, thickening the high viscosity semi-synthetic oil, and add There are a variety of additives and molybdenum disulfide solid fillers in the production of heavy-duty coupling grease. Recommended for the world famous gear coupling manufacturers Maina, has accumulated rich experience in the use in Europe. It is worth mentioning is that the product Timken OK value by 75 pounds, showing excellent resistance to extreme pressure properties, and therefore can be widely used in other low-speed heavy burden and location.

Usually grease is mainly used for the lubrication of rolling bearings, in many cases, these greases are not suitable for lubrication of coupling, this is due to the work characteristics of the bearings and flexible couplings, there are many differences.Pay is basically in the rolling friction (ball bearing), or mainly in rolling friction with sliding friction (roller bearing) friction in the bearings; In addition, the vast majority of grease in the bearings in a quiescent state, through the oil separator and the flow of a small amount of grease to the lubrication points added new grease. 2 # and 3 # consistency of the grease in the bearing in most cases the formation of the state of the channel flow is conducive to bearing seal and lower bearing temperature rise, while too large, the adhesion will increase the bearing temperature and power consumption is not conducive to bearing lubrication.
