Description
技术领域 technical field
本发明属于机械制造与装配领域，尤其涉及一种丝杠和滚动轴承组件装配方法。 The invention belongs to the field of mechanical manufacturing and assembly, and in particular relates to an assembly method of a lead screw and a rolling bearing assembly.
背景技术 Background technique
装配是注塑机产品制造过程的后期环节。如何把组成机器的各个零件正确地安装在一起，形成完整产品，并且达到期望的精度，这是生产工程中所要解决的问题。经过精心设计装配方法，在保障机器性能的同时，可以显著降低制造成本，同时大大提高生产效率。 Assembly is the later link in the manufacturing process of injection molding machine products. How to correctly install the various parts that make up the machine together to form a complete product and achieve the desired accuracy is a problem to be solved in production engineering. After carefully designing the assembly method, while ensuring the performance of the machine, the manufacturing cost can be significantly reduced, and the production efficiency can be greatly improved at the same time.
电动注塑机中的滚珠丝杠是一种精密传动元件，在装配时除了应保证丝杠与工作台直线导轨的水平和垂直方向平行度、轴承座与螺母的同轴度外，还要保证滚珠丝杠本身的旋转精度，即径向跳动和轴向窜动精度。因为，滚珠丝杠副仅承受轴向负荷，径向力、倾覆力矩会使滚珠丝杠副产生附加表面接触应力等不良负荷，从而产生永久性损坏。所以，设计合理的装配方法，实现滚珠丝杠副的正确安装对使用性能具有重要的决定作用。在安装滚珠丝杠的过程中，既要严格控制滚珠丝杠的轴向窜动量，以保证传动位置精度；又要防止径向和偏置载荷，以减少丝杠绕度。 The ball screw in the electric injection molding machine is a precision transmission component. In addition to ensuring the horizontal and vertical parallelism between the screw and the linear guide rail of the worktable, and the coaxiality between the bearing seat and the nut, the ball screw must also be ensured during assembly. The rotation accuracy of the screw itself, that is, the radial runout and axial movement accuracy. Because the ball screw pair only bears the axial load, the radial force and overturning moment will cause the ball screw pair to generate additional surface contact stress and other undesirable loads, resulting in permanent damage. Therefore, designing a reasonable assembly method and realizing the correct installation of the ball screw pair play an important role in determining the performance of the ball screw. In the process of installing the ball screw, it is necessary to strictly control the axial movement of the ball screw to ensure the accuracy of the transmission position; it is also necessary to prevent radial and offset loads to reduce the winding of the screw.
