提出了两种调整圆柱蜗杆传动啮合侧隙的方法:通过改变蜗轮蜗杆的啮合中心距来改变其啮合侧隙;采用双导程蜗杆传动以调整蜗轮蜗杆的啮合侧隙,简述了调整原理,并比较了两种调整方法各自的特点。%The paper suggests two methods for adjusting the mesh clearance in cylindrical worm drive:one is to adjust the meshing center distance of worm gears,the other is to use dual lead cylindrical worm, introducing briefly the principle of adjustment and making a comparison between the characteristics of the two methods.
