Research On Theory Of Dividing Balls With Fluid In Assemble Of Ball Bearing

It is known that wave-shaped cage is loaded to the bearings in the assembly of ball bearing automatically. Firstly, balls are gathered by a gathering-ball device, and then divided equally in the channel of bearing. The principle of dividing ball with fluid is researched in this paper. And the main study is how to use the principle of fluid to divide balls equally between the ball bearings inside and outside the ring in the channel in order to complete the assembly of Cage.Firstly, the characteristics and background application of ball-bearing are introduced, especially the research and development situation of the equipment technology about dividing ball both at home and abroad in this paper. And the deficiency of those equipment is pointed out. In order to resolve these issues, the principle of dividing ball with fluid is proposed. Bernoulli's equation and the full-bridge damping network may explain the mechanism of dividing ball with fluid in detail.Secondly, the force and motion analysis of the balls under the power of fluid is analysed. The flow characteristics of fluid around the ball and the surface of viscous fluid flows around the ball, that is the problem of flow around the object, also known as boundary layer problems is introduced. Nextly, the main analysis of flow velocity distribution, the surface of the ball at the ball in the process of thrust by the fluid and cause flow separation due to the lift and so on. According to a rigid body rotating around the fixed-point ball bearing assembly to draw Euler equations of fluid movement at the ball movement Euler formula, so as to arrive at the form of its movement.Furthermore, a commercial computational fluid dynamics software FLUENT is introduced, and the model of fluid-pointers is built.Application of numerical equations, simulation of flow field at the ball Fluid-pointers in accordance with the working principle of the ball made According to the The principle of dividing ball with fluid, the various sub-factors are Summarized. The key factors is analysed, and a series of conclusions are obtained..Finally, the principle of fluid at the design of ball-point ball bearing assembly device demonstration of the feasibility of fluid-pointers is disscussed. Through experimental research to prove the correctness of the theory, to some extent, demonstrated the reliability of numerical simulation at the same time. On this basis, some constructive suggestions about the improvement of equipment are raised to help fluid-pointers for further theoretical research equipment.
