B1 蝸桿軸伸上，由于安裝齒輪.鏈輪或帶輪所產(chǎn)生的徑向力，其***大許用力與起升力和型號(hào)有關(guān)。在1/2處所許用的***大徑向力和扭矩見圖B1和表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.
