The load force of rolling bearings

When learned how each ball or roller bearing load bearing ( As defined in chapter 5) After the load between the ball and roller bearings is how to allocate is possible. To do this, you must first establish play moving bodies and raceway contact load displacement relationship. With the aid of chapter 2 and chapter 6, can build any type of hydraulic body with any kind of raceway contact load - The displacement relationship. As a result, the content of this chapter is entirely up to the front several chapters, in order to facilitate understanding, to quickly review the relevant content is good. In most dynamic bearing applications, or the inner ring, or the outer ring, or the inner and outer ring in stable operation at the same time, surface and speed is usually not very high, so will not make the ball or roller produces large enough inertia force and obvious influence on the load distribution between the roller. In addition, in most applications, the friction force and moment acting in a moving body also won't produce significant effect for load distribution. Therefore, when determining the distribution of hydraulic load, ignore the influence of these factors in most applications usually can be brought to a satisfactory conclusion. Before, on the other hand, widely used in numerical calculation, analysis of load distribution for this has put forward some relatively simple and effective method. This chapter will also use these methods to study the static load under the action of load distribution of ball bearings, or roller bearings. 7. 2 load - By type (displacement relationship 6. 42) It can be seen that for a given ball - Raceway contact ( The point contact) , there are eight ( 7. 1) The type ( 7. 1) Transformation, and written form equation O = A ( 7. 2) Similarly, for a given roller contact ( Line contact) , there is Q = A62 ( 7. 3) Miraculously, there are ( 7, 4) Type of ball bearing, n = 3/2 ( = 1. 5) ; For roller bearing, n = 10/9 ( = 1. 11) 。 Under the load, separated by a rolling element method between two acting way to reaching the amount equal to play moving bodies and the sum of the amount of almost every race, so 6. = 6 + 67. 5) ( 7. 6) ( 1 / K1) + ( 1 / K, and ( 7. 7) Q = A, 6 ° for contact with steel ball and fluid passage, there are ( 7. 8) ,=215x0p( 6 also, for the steel roller and raceway contact, 79) K = 8。 06107. 3 under the radial load bearing for the rigid support under radial load bearing, in any Angle position of the hydraulic radial displacement is zero.
