The safety of the bearing greases of rolling bearing is very important, ordinary attempting to choose 3 of the greater consistency grease, not smaller viscosity grease. And in contrast, in order to reduce bearing gone and, particularly, start to turn gone, to average speed is not too high bearing, it's all can choose low viscosity grease is advisable.
Fat than base oil plastic viscosity achievements of viscosity, and grease membrane has clear elasticity, so its resistance to load ability than base oil. Just base oil viscosity and proper, the grease of load ability are not the results. In the boundary lubrication or extreme pressure lubrication condition, main is relying on additive to improve the abrasion resistance and extreme pressure function, to meet the requirements of the lubrication condition.

Good use of grease, must know fat in the motion bearings. Fill in the rolling bearing grease of movement, along with the rotation of the bearing, by and large, can be divided into two phases. In ordinary circumstances, the bearing grease filling quantity, always exceeds the directly involved in the demand for lubrication theory, in the early stages of the bearing expect them, most of the grease soon (less than a minute) will roll out of the way, and piling up in adhere to the rack and bearing guards empty cavity, and in the center of roller to form a contour. In this process lu, because the resistance of the redundant grease, bearing temperature rise soon. Although most of the redundant grease in the early operation that extrusion, and squeezed in a groove accessories grease of still also has turned the roller can be brought into the groove between. These grease in as bearing drive the systemic circulation at the same time, they have a large number of be eduction. Then bearing yavin degrees still continue to rise until the redundant grease was all so far out,

Can be called the grease ZouGe stage, according to the structure of bearing grease filling quantity, quality and so on elements, this time can last more than ten minutes or even hours.

The rest of the grease was completely after discharge, the rest of the large number of grease in rolling body, groove, adhere to the frame of mutual contact surface, JianPi role by a thin thin film grease, thus the normal expect them into bearing stage. Then the temperature gradually decline and arrived in balance shapes. That is, temporary lubrication, main is relying on this layer to bear grease membrane. In addition, in the process of operation for bearing, rolling body and groove near the outline of the outline of and adhere to the frame to atrophy and gives grease part of base oil, flow into the groove after between, the lubrication also to have certain supplementary role.

Different grease in bearing a open to traffic in outline is not the same, must constitute outline is pretty is, ZouGe time is short, the operation in temporary bearing low temperature, and turbulence, this is an ideal grease, so for the grease into the sex is especially important.
Some so-called type vortex grease is different, is not easy to form outline, even if a contour also easy to collapse, then repeated back to roll tract of the redundant grease temporarily in the condition of the stir strong column, bearing great torque, high temperature, and don't balance, can also attack noise, grease and easy to change and loss.
