Description
Technical field
The utility model relates to a kind of traction walking mechanism, and specifically a kind of traction walking mechanism of drum shearer belongs to the coal mine machinery technical field.
Background technology
According to national coal storage total amount, thin and ultra-thin coal seam is widely distributed in China, having more than 80 office to compose in 95 the emphasis mineral bureaus in the whole nation deposits thin and ultra-thin coal seam, whole nation State owned coal mine is thinner than 25.29 hundred million tons of ultra-thin coal seam reserves, mainly is drum shearer for thin employed equipment with the ultra-thin coal seam exploitation in the industry at present.Drum shearer mainly is tractive force to be provided and to be transferred to walking mechanism via gear by haulage gear to drive whole device motion in the course of the work.But because environmental limit in the work; in the situation of thin and ultra-thin coal seam high inclination-angle; because machine height is restricted; often can appear as and guarantee the strength of gear teeth and tractive force phenomenon not enough and that cause the strength of gear teeth to be damaged not owing to tractive force is excessive; affected the normal service efficiency of device; increase the exploitation difficulty, thereby reduced the mechanization degree of high inclination-angle ultra-thin coal seam.
The utility model content
For the problem that above-mentioned prior art exists, the utility model provides a kind of traction walking mechanism of drum shearer, strengthens the strength of gear teeth, strengthens tractive force, guarantees the service efficiency of drum shearer, improves the mechanization degree of high inclination-angle ultra-thin coal seam.
To achieve these goals, the technical solution adopted in the utility model is: a kind of traction walking mechanism of drum shearer, formed by tractive unit and running part, tractive unit and running part are bolted, tractive unit comprises and leads an axle, lead two axles, motor, lead three axles, lead four axles, lead five axles, planetary mechanism and lead six axles, running part comprises the walking axle, also comprise shunt shaft, power transmission shaft and interflow axle, shunt shaft is two, be arranged in the tractive unit, left end is symmetricly set on and leads six axle both sides, by the gear on the axle and the gear engagement of leading on the six axle axles, the right-hand member spline is connected by spline housing with power transmission shaft left end spline, the interflow axle is two, is arranged in the running part, and the left end spline is connected by spline housing with power transmission shaft right-hand member spline, right-hand member is symmetricly set on walking axle both sides, by the gear engagement on the gear on the axle and the walking axle axle.
The utility model arranges two shunt shafts in the traction walking mechanism of drum shearer, motor is by leading an axle, lead two axles, lead three axles, lead four axles, leading five axles, planetary mechanism transfers a torque to and leads six axles, leads six axles and branches to shunt shaft realization power dividing, shunt shaft transfers a torque in the running part two interflow axles by power transmission shaft, the interflow axle collaborates power to the axle of walking, and drives whole device motion by the walking axle.In the whole transmission course, owing to being provided with two shunt shafts, power transmission shaft and interflow axle, reduce single gear holding capacity, and increased the strength of gear teeth, and further improved tractive force in the situation that guarantee the strength of gear teeth, thereby guaranteed that drum shearer normally uses, and has further improved the mechanization degree of high inclination-angle ultra-thin coal seam in the situation of thin and ultra-thin coal seam high inclination-angle.
