Problems solved by technology

For example, the rocker arm of the reciprocating impact roadheader is a retractable structure, the rocker arm of the reciprocating impact shearer is a liftable structure, that is, it needs to be adjusted and moved, and the roller support rocker arm of the roller harrow loader needs to move back and forth in order to rake the material, etc. The above equipment The telescopic movement of the working parts relative to the fuselage is sliding friction, the sliding friction resistance is large, and the breaking force is large. In order to improve work efficiency and applicability, the working heads of roadheaders, coal shearers, and loaders are made large. , Heavy weight, heavy weight and bulky working head against the sliding telescopic guide rail due to its heavy gravity and heavy reciprocating wear, it is prone to crawling and shaking during work, and in serious cases, the sliding friction surface will be bonded and burnt. The most critical thing is due to the working environment. Particularity It is not easy to form a uniform lubricating oil film on the friction surface, which will cause friction to generate heat and cause the movement adjustment to fail
In order to avoid the failure of the rocker arm telescopic sliding friction, many manufacturers do not use the telescopic rocker arm. If the rocker arm is not allowed to move telescopically relative to the fuselage, the use efficiency and adaptability will be seriously reduced. In order to reduce the sliding friction resistance, shortening the slideway will cause Short telescoping distance of the rocker arm, small mining and / or loading and reclaiming range, poor adaptability, low work efficiency, etc.
