B1 蝸杆軸伸上，由于安裝齒輪.鏈輪或帶輪所産生的(de)徑向力，其***大(dà)許用(yòng)力與起升力和(hé)型号有關。在1/2處所許用(yòng)的(de)***大(dà)徑向力和(hé)扭矩見圖B1和(hé)表B1。
B1 As gear, chain wheel and pulley are mounted on worm shaft end, it makes radial force F1. The maximum allowadle force is depend on lifting force and model. The maximum allowable radial force and trosion at 1/2 position are shown in Fig B1 and B2.
