105勘探队修配车间工人燕丕忠同志,创造螺旋齿轮铣床获得成功。经过实践证明效果良好。构造如图1所示。铣床机架用角钢制成,机座(10)用螺栓固定于机架上。机座(10)上装置电动机(1)带动大三角皮带轮(11)。大三角皮带轮(11)轴上装置铣刀(12)。形状如图2(根据500米钻探机螺旋齿轮尺寸设计的)。铣刀(12)系用高速钢制成的(指形铣
105 exploration team repair shop workers Comrade Yan Pi Zhong, to create a spiral gear milling machine success. After practice proved effective. Structure shown in Figure 1. Milling machine frame made of angle, the base (10) bolted to the rack. The motor (1) on the base (10) drives the V-belt pulley (11). Large triangular pulley (11) shaft cutter (12). The shape is shown in Figure 2 (based on the size of a 500m drilling machine helical gear). Milling cutter (12) is made of high-speed steel (finger milling
