A new type roller is first put forward in this paper ? ? rolling screw roller. there is something improved and enhanced on the basis of traditional roller. the rolling screw roller can absorb shocks more efficiently, can reduce noise and vibration during transmission, and extended roller useful life, thus extending the useful life of the chain
卷制螺旋滾子不同於以往傳統滾子是通過冷擠壓成型，它是通過絲材卷製成型的，因此，它周身遍布縫隙，整個縫隙呈螺旋狀，在工作中，可以依靠這些縫隙吸收沖擊能，減少高速多沖對滾子造成的傷害。In this paper a newly develoed helical coordinates is used to make out the solution of electromagnetic fields in the helix gap and calculate dispersion characteristics of tape helix slow wave structure for the first time. strict boundary conditions for magnetic fields are adopted and are treated rigorously by fourier expansion. besides, the radial propagation constant of every layer in the dielectric - loaded region is differentiated. some of practical tape helix slow wave structures have been calculated for dispersion characteristics and the calculated values accord with measured values very well. the authors also compare the calculated results with experiments for different structures by changing tape thickness or other structure parameters and find that the theory in the paper is universal
本文首次運用螺旋坐標系給出了帶狀螺旋線縫隙內的電磁場解，並據此計算了帶狀螺旋慢波結構的色散特性.文中採用了嚴格的邊界條件，並以傅立葉展開進行了嚴格的數學處理.另外還首次對有介質區域內各層的徑向傳輸系數作了區別.本文使用這種方法計算了我們已研製的一些寬帶高功率行波管所用的慢波線結構的色散特性，理論與實驗符合得很好.我們還計算了不同結構參數對色散特性的影響，並與實驗作了對照，發現本文的理論有一定的普適性
