S195柴油机使用元筒形带止推边的主轴瓦,该轴瓦自采用20锡铝合金-钢双金属复合板生产后,普遍存在止推边与筒体结合强度低的问题,严重影响装拆使用质量。我厂在学习兄弟单位先进经验的基础上,将止推边与筒体的联结由原来的铆接工艺改为摩擦焊接工艺,并设计试制成一台MCH-10型摩擦焊机,在1977年1月投入生产。采用摩擦焊接后,该主轴瓦止推边与筒体的结合强度可达3～5吨,比原结构强度提高10倍以上。 摩擦焊接是目前国内外普遍重视的新工艺
S195 diesel engine using the main cylinder sleeve with a thrust edge, the bush since the use of 20 tin-aluminum alloy - steel bimetallic composite production, there is widespread thrust side of the cylinder with a low bond strength, seriously affecting the demolition of the use of quality. On the basis of learning advanced experience from our brother unit, our factory changed the connection of thrusting edge and barrel from the original riveting process to the friction welding process and designed and manufactured a prototype MCH-10 friction welding machine. In 1977, January production. After friction welding, the main bearing thrusting edge of the barrel with a combination of strength up to 3 to 5 tons, 10 times more than the original structure to improve strength. Friction welding is the new technology which is generally valued at home and abroad
