Q: Dynamic characteristics of rolling bearings.
A: Transmitting motion and load is the basic function of rolling bearings, and it also determines the dynamic characteristics of the bearing service process. The force of rolling bearings is high stress value and high frequency alternating load under elastic contact.
Whether it is a ball bearing or a roller bearing, since the contact between the ball (roller) and the groove (raceway) is point (line)shaped, the contact surface is very small when considering elastic deformation, so the stress value is very large. When there is clearance, the rotation speed will make the rolling bodies with different loads pass through the load zone of the bearing repeatedly; every turn, each rolling body will repeatedly alternate in the form of minimum load-maximum load-minimum load-zero load; the contact area will deform at a high frequency with the stress alternation. This dynamic characteristic of the working surface of the bearing makes it very complicated to quantitatively analyze and study the service performance of the bearing; it is necessary to complete a large number of mechanical experiments, accumulate sufficient data, and conduct tedious statistical analysis to establish a mathematical-physical model. The mechanical analysis of bearings has gone through nearly 200 years, from static elasticity to engineering applications of pseudo-dynamic analysis, and mature dynamic simulation has not yet been completed. In addition to the long-term accumulation of experimental data, the completeness of analysis and calculation tools is also an indispensable condition.
