The utility model comprises an external engaging gearing, a two stage planetary reduction apparatus, an output gear shaft, a drive gear and the like. The external engaging gearing and the two stage planetary reduction apparatus of the utility model together accomplish the triple speed reduction. The utility model has the advantages of perfect effect, steady driving, small starting moment, little gear abrasion, long service life and high bearing capacity. The utility model is especially applicable to the utilization of tower machines.
Description
Technical field: the utility model relates to the improvement of the speed reducer that a kind of tower machine uses, specifically a kind of planet-gear speed reducer.
Background technique: according to the knowledge of the applicant, at present, the tower machine is various in style with speed reducer, planet-gear speed reducer more commonly, this speed reducer adopts the secondary planetary gear speed reducer, because starting torque is big, and the reducer gear serious wear, reduced working life, made its application in practice be subjected to certain restriction.
Summary of the invention: technical problem to be solved in the utility model overcomes the deficiency of above-mentioned technology exactly, provide a kind of planet-gear speed reducer that on the basis of former secondary planetary gear speed reducer, adds the one-level speed reducer in addition, with purpose such as realize that starting torque is little, gear wear is little, long service life, bearing capacity are strong.
The technological scheme that its technical problem that solves the utility model adopts is a kind of planet-gear speed reducer, it is by the external gear pump device, the secondary planet speed reducer, parts such as output gear shaft and driving gear constitute, it is characterized in that the secondary planet speed reducer comprises identical two cover planetary gear system, every cover planetary gear system is by the transmission sun gear, transmission planet wheel and transmission planet stent constitute, wherein the transmission sun gear is meshed with three transmission planet wheels, the transmission planet wheel is meshed with the ring gear of transmission planet stent, by internal spline two cover planetary gear system are fused between secondary transmission planet stent and three grades of transmission sun gears, three grades of transmission planet carriers are connected with output gear shaft by internal spline.
The utility model external gear pump device and secondary planet speed reducer are finished three grades of decelerations jointly, and starting torque is little, and is effective, stable drive.Have that gear wear is little, plurality of advantages such as long service life, bearing capacity are strong.
Description of drawings: the utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Embodiment: as can be seen from Figure 1, a kind of planet-gear speed reducer of the utility model, it is made of parts such as external gear pump device, secondary planet speed reducer, output gear shaft 9 and driving gears 10.Wherein, the external gear pump device is made up of one-level driving pinion 1 and 2 engagements of one-level transmission gearwheel, one-level driving pinion 1 is connected with motor by fluid coupling, secondary transmission sun gear 3 engagements in one-level transmission gearwheel 2 and the secondary planet speed reducer.The secondary planet speed reducer comprises two cover planetary gear system, and every cover planetary gear system is made of transmission sun gear, transmission planet wheel and transmission planet stent.Wherein secondary transmission sun gear 3 is meshed with three secondary transmission planet wheels 4, and secondary transmission planet wheel 4 is meshed with the ring gear of secondary transmission planet stent 5; The second cover planetary gear system is identical with the first cover planetary gear system, and three grades of transmission sun gears 6 are meshed with three three grades of transmission planet wheels 7, and three grades of transmission planet wheels 7 are meshed with the ring gear that three grades of transmission planet stents 8 support.By internal spline two cover planetary gear system are fused between secondary transmission planet stent 5 and three grades of transmission sun gears 6, three grades of transmission planet carriers 8 are connected with output gear shaft 9 by internal spline.External gear pump device and secondary planet speed reducer are finished three grades of decelerations jointly.
When motor start-up, the one-level driving pinion drives one-level transmission gearwheel and rotates, and finishes one-level and slows down, and one-level transmission gearwheel drives the secondary planet speed reducer again and carries out second and third grade deceleration, by output gear shaft final rotating speed is passed to driving gear at last, realize three grades of decelerations.
The utility model is simple in structure, and it is effective to slow down, stable drive, long service life.Being particularly suited for the tower machine uses.
