内燃机摇臂曲面修复及磨削夹具设计

Restoration of Shaft Surface of Rocker Arms and Design ofFlxtures for Their Grinding

随着交通事业的发展，我国已先后购进国外各种车辆４００万辆左右，由于顶置式气门内燃机的摇臂，比发动机上其它零件的体积和重量小，因此我国对摇臂的修复一直没有引起重视，进口汽车摇臂的损坏，需要用外汇购进新的配件，从节约出发，修旧利废是最直接的方法。

With the developing of transpartation industry,about 4 millions of various vehicles abroad have been now inported to our country.We usually neglect to restore the parts,for the rocker arms of head-valve internal combustion engines are smaller than any other parts of the engine both in size and in weight.Once the rocker arms are damaged or worn out,new parts for the replacement need inporting at cost of foreign exchange.The restoring process is an economical and effective approach to the solution.
