135系列柴油机汽缸套内孔的精加工,工艺规定要进行珩磨。珩磨后,由于煤油冷却液中混有许多铁未影响了继续使用,后来,我们制成了磁性滤清器,它可以方便地清除混杂在煤油中的铁末,使用后效果很好,现作一介绍。结构结构见图1.在0.6kW、1420rpm的电动机转轴上装有m=3、z=1、螺距t=9.421mm、右螺旋升角β=4°45＇49″的蜗杆与m=3、z_k=100的蜗轮啮合,蜗轮上装置一摇臂H,摇臂H上装有滑动齿轮z_z 135 series diesel engine cylinder bore hole finishing, the process requires honing. After honing, due to the kerosene coolant mixed with many iron did not affect the continued use, and later, we made a magnetic filter, which can easily remove the mixed iron in the kerosene, the effect is very good, now An introduction. The structure is shown in Fig. 1. At 0.6kW and 1420rpm, the worm with m = 3, z = 1, pitch t = 9.421mm, right helix angle β = 4 ° 45’49 "and m = 3, z_k = 100 worm gear meshing, the worm gear on a rocker arm H, rocker arm H equipped with a sliding gear z_z
