EN:Problem. To overcome rolling resistance and rolling repair units spent heavily countries. Since one of the major cost elements are overcoming rolling resistance in of ball and roller bearings, it is necessary to more accurately determine its value and in particular the coefficient of rolling friction transferred to the shaft. Its value is given in the references and recommended for of ball bearings, roller bearings in [1]. These differences should be attributed to the material holders and balls and rollers, as well as due to viscosity oils.
The purpose of the article. Submit Analytical relations for determining rolling resistance balls and rollers for different schemes of touch and give more accurate values of the coefficient of rolling friction reduced to shaft or bearing internal cage.
Analysis of the main indicators of the calculations bearing units with different schemes of touch suggests:
– Obtained dependence of the resistance movement;
– Dependences coefficient of rolling friction of the load allowable on the ball and the cylinder will make for rational analysis unit bearings in terms of size and power consumption.
