At hoist work occasion, the rope drum of hoist equipment generally needs to be driven by the speed reducer speed reduction, and the speed reducer that is used for hoist equipment of prior art, hoist speed reducer promptly, and the erection joint between the hoist rope drum is inconvenient, and the structural dimension of hoist speed reducer is great simultaneously, and the transmission shaft rigidity that is close to the input position is short of, and the during operation sometimes vibration can be on the large side, can not guarantee the reliability of work for a long time.
Disclosure of Invention
Not enough to prior art exists, the utility model aims at providing an easy to assemble, compact structure rigidity is good, guarantees the trinity hoist speed reducer of the parallel shaft of reliable operation.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to accomplish:
trinity hoist speed reducer of parallel shaft, including the reduction box, internal parallel of reduction box is equipped with preceding transmission shaft, rear drive axle and output shaft, the external fixed mounting motor of reduction box, the motor shaft passes through transmission shaft before the gear engagement transmission, and preceding transmission shaft passes through gear engagement transmission rear drive axle, and the rear drive axle passes through gear engagement transmission output shaft, its characterized in that: the two ends of the output shaft are rotatably supported by a left self-aligning bearing and a right self-aligning bearing, the left shaft end of the output shaft extends out of the reduction box body, an outer gear which can be meshed with an inner gear ring arranged on the end face of the winch rope drum is fixedly arranged on the outer circle of the extending part, a supporting hole is formed in the end face of the extending part, a small self-aligning bearing for rotatably supporting the central shaft of the winch rope drum is arranged in the supporting hole, a left end cover is arranged outside the left self-aligning bearing and fixed outside the reduction box body through screws, an end cover hole is formed in the left end cover and allows the output shaft to pass through, and a lip seal is arranged between the left end cover and the reduction box body.
The width of the right self-aligning bearing is larger than the wall thickness of the box body at the position of the right self-aligning bearing hole of the reduction box body, the outer end of the right self-aligning bearing is supported by the inner hole of the right end cover, and the right end cover is fixed outside the reduction box body through screws.
The left shaft end of the front transmission shaft is rotatably supported by a rolling cone bearing, the reduction box body is provided with a rolling cone bearing hole at the top of the boss, the boss is formed on the inner wall of the left box body of the reduction box body, and a smaller span is formed between the top of the boss and the inner wall of the right box body of the reduction box body.
By adopting the technical scheme, the hoisting speed reducer is convenient to connect with the rope drum of the hoisting machine and convenient to install, meanwhile, the weight is reduced by reducing the wall thickness of the box body at the right side of the speed reducer box body, so that the structure of the speed reducer is compact, and on the basis, a right aligning bearing for supporting the right shaft end of the output shaft is still well supported and ensured through the inner hole of the right end cover; in addition, the support span of the front transmission shaft is reduced through the boss, the rigidity of the transmission shaft close to the input end is improved, and the phenomenon that the vibration of the speed reducer is large sometimes during working is avoided, so that the working reliability of the speed reducer is better ensured for a long time. The winch speed reducer is connected with the winch rope drum in such a way: after the hoisting speed reducer is installed in place, the right side end of the hoisting rope drum is pushed towards the direction of the input shaft, the right end shaft head of the central shaft of the hoisting rope drum is sleeved into an inner hole of a small adjusting bearing installed in a supporting hole, the inner gear ring installed on the end face of the hoisting rope drum can be in gear engagement with an outer gear installed on the shaft head of the output shaft, then a bearing seat supporting the left end shaft head of the central shaft of the hoisting rope drum is fixed, and the installation and connection are very convenient.
