ND_2内燃机车转向架的支承装置中,有一对球面付——球面体与支承。过去球面体和支承是用人工研磨,不仅生产率低(每人每天只能磨1～2套),而且,劳动强度很大,很难达到图纸中70%的接触面的要求。根据上述情况,我厂利用土办法,制作出一套机械研磨机来代替人工研磨。机械研磨机是利用一台立钻做动力头,其构造见附图。压杆6装到立钻的主轴上,压杆与弹簧垫用球
ND 2 diesel locomotive bogie support device, there is a pair of spherical surface to pay - spherical body and support. In the past, spherical bodies and supports were ground by hand. Not only the productivity was low (only 1 or 2 sets per person per day), but also the labor intensity was so great that it was difficult to meet the requirements of 70% of the contact surfaces in the drawings. According to the above, I plant the use of soil method, to produce a set of mechanical grinding machine instead of manual grinding. Mechanical grinding machine is the use of a vertical drilling power head, the structure shown in the drawings. Rod 6 mounted to the spindle, the pressure lever and spring pad with the ball
