Rolling bearing center thrust load calculation

Thrust load center under thrust load at the centre of the ball and roller bearings of all rolling element have the same load. Therefore, Q = 1 s ( 7. 26) Sina type, a is the contact Angle of under loading. For small contact Angle 90 ° of thrust ball bearings, their load under the action of the contact Angle of than no load when the initial contact Angle of a °. This kind of phenomenon will be discussed in more detail in the following sections. 7. 4. 2 angular contact ball bearing with no centrifugal force load, internal and external raceway contact Angle is equal, but they should be greater than the contact Angle of no load condition. No load state, the contact Angle is defined as the P7. 27) 2 bd type, P. Is the radial clearance after installation. As shown in figure 7. 4, the thrust load F. ACTS on the inner ring will be ー an axial displacement of 8. 。 From figure 7. 4, you can see that the axial displacement is along the line of contact component of the normal displacement in the direction of this chapter puts forward the rolling bearing of ball and roller load distribution calculation method suitable for bearings in a low speed applications. Under the condition of this speed, the centrifugal force and gyroscopic moment of roller can be ignored. And under the condition of high speed, the force will become very important, they will change the contact Angle and internal clearance, which to a large extent affect the internal load distribution. In the previous discussion, the relatively simple calculation method was used to determine the internal load distribution. With the help of the book provides tables and graphics data, by hand calculation method can get results. In later chapters of the book. 2, in order to evaluate three degrees of freedom in ball bearings and roller bearings or five degrees of freedom in the load, the influence of the roller bearing fluid tilt and the influence of the thrust load and the influence of non rigid ring, etc. , must adopt numerical calculation method. But for many applications, this chapter provides relatively simple approach can be used effectively. This chapter also shows that the bearing of the radial and axial displacement is a function of the internal load distribution. However, due to the contact stress depends on the load, so the maximum contact stress of bearing is also a function of load distribution. As a result, controlled by the stress level of bearing fatigue life will naturally affected by rolling load distribution of significant. 2. 1 in 20 DCBB bearing radial load is applied, by 89 n try to determine the load of each ball and raceway.
