托辊配件重要性
Importance of idler fittings
托辊配件能够在托辊的使用中发挥重要的作用和价值，能够辅助托辊的使用和维护，帮助用户在维护托辊时发挥重要的作用和价值。
The supporting roll fittings can play an important role and value in the use of supporting rollers, assist the use and maintenance of supporting rollers, and help users play an important role and value in the maintenance of supporting rollers.
托辊配件的生产加工精度主要指外壳及托辊两端内孔的同心度以及各零件轴向尺寸的加工精度。若同心度太差，会造成滚动轴承咬死、增加阻力，降低使用寿命;若零件的轴向尺寸误差太大，会形成较大的轴向间隙，导致轴向窜动，破坏润滑和密封;若安装质量不好，将发生跑偏、咬卡、加剧磨损等，大大降低托辊使用寿命。如何合理布置托辊，设计恰当的托辊组间距，以减少托辊的使用数量，降低整机价格，减少投资、营运及维护费用，提高经济效益，托辊的加工工艺是一个重要的方面。
The manufacturing accuracy of idler fittings mainly refers to the concentricity of the inner holes at both ends of the shell and idler and the processing accuracy of the axial dimensions of each part. If the concentricity is too poor, it will cause the rolling bearing to bite, increase the resistance and reduce the service life; if the axial dimension error of the parts is too large, it will form a larger axial clearance, leading to axial movement, destroying lubrication and sealing; if the installation quality is not good, there will be deviation, clamping, aggravating wear and tear, etc., which will greatly reduce the service life of the idler. 。 How to arrange idlers reasonably and design proper spacing between idlers to reduce the number of idlers, reduce the price of the whole machine, reduce investment, operation and maintenance costs, and improve economic efficiency, the processing technology of idlers is an important aspect.
