Background technology

Existing inside and outside its speed reduction gearing of dress motorized pulleys adopts inside and outside double reduction, or even the gear transmission of three grades of decelerations, or the cycloidal-pin wheel transmission.For realize in the motorized pulleys, low belt speed operation, existing speed reduction gearing need adopt the multistage type of drive of secondary or three grades, its complex structure, turn(a)round weak point, inconvenient maintenance, range of use be restricted; Though and general outer dress cylinder has overcome the problem of motor radiating, the transmission device complexity is applicable to the middle low power occasion use that 75KW is following substantially, and is not competent in occasions such as flourishing day by day harbour, mines.For the air pressure of balancing drum intracoelomic cavity, directly at the air passage air extractor duct connection abat-vent in axle center, there is oil seepage phenomena in the prior art, waste machine oil, contaminated environment like this.

Summary of the invention

The present invention overcomes the defective of above-mentioned existence, and a kind of employing modularization star-wheel core cell is provided, by the one-level speed change realize that noise is low, the life-span long, in low belt speed, fitted outside involute less tooth difference star-wheel motorized pulleys that load-carrying capacity is big.

In order to achieve the above object, the present invention adopts following technical scheme: a kind of exterior-mounted star wheel motorized driving pulley, comprise left support abutment, left end cap, barrel, anchor shaft, hollow shaft, right end cap, right support abutment, input shaft, technical characterstic is to be provided with planetary-gear speed reducer in the barrel, planetary-gear speed reducer is connected on anchor shaft and the hollow shaft through left step disk and right step disk, and the planetary wheel of planetary-gear speed reducer is the rotation that engagement realizes barrel with the inner gear that is fixed on the barrel.

Further, described planetary-gear speed reducer comprises left step disk, bolster, planetary wheel, eccentric spider gear shaft, eccentric bushing, right step disk, left side step disk and right step disk are connected into pinion carrier through many bolsters, pinion carrier is connected in respectively on anchor shaft and the hollow shaft through left step disk and right step disk, eccentric bushing is installed on the input shaft, through capacity eccentric bearing two planetary wheels are installed on the eccentric bushing, two planetary wheels connect through many eccentric spider gear shafts, and the two ends of eccentric spider gear shaft are installed on respectively on left step disk and the right step disk through lining and antifriction-bearing box.

Also comprise, be evenly equipped with many bolster axis holes and many eccentric spider gear shaft axis holes on described two planetary wheel circumference respectively, bolster axis hole and eccentric spider gear shaft axis hole are spaced apart, many bolsters that connect left and right step disk run through the bolster axis hole respectively and do not contact with the bolster axis hole, connect two planetary many eccentric spider gear shafts and connect through eccentric spider gear shaft axis hole and with spider gear shaft bearing sleeve in the axis hole respectively.Described anchor shaft axle head is provided with abat-vent, and the circuitous air flue in abat-vent and the anchor shaft is communicated to the barrel inner chamber.

After adopting above technical scheme, the beneficial effect that the present invention reaches is: planetary-gear speed reducer adopts the power flow dividing structure of the high internal gear pair of meshing efficiency, by continuous pure rolling ground transmitting torque of high bearing capacity rolling star-wheel and rotating speed, maximum delivered power can reach 320KW, ratio coverage is big, the one-level transmission speed ratio can reach 18-80, can satisfy the needs of complete series belt speed, minimum band scooter 0.4m/s.The planetary-gear speed reducer core cell has nearly that 14-28 meshes simultaneously to tooth, and shock-resistant, stable drive, noise is low, the life-span is long, gear freedom from repairs use for a long time.Since the planetary-gear speed reducer core unit moduleization, its compact conformation, dependable performance, easy to maintenance, and gear freedom from repairs for a long time uses.Connecting abat-vent behind the other bleed road on the air passage in anchor shaft axle center, oil seepage phenomena can not appear.

The specific embodiment

A kind of exterior-mounted star wheel motorized driving pulley shown in Fig. 1, Fig. 2, motor 1 connects with input shaft 3 by coupler 2 (or hydraulic coupler), and input shaft 3 is by two cylindrical roller bearings in hollow shaft 6 and left step disk 19 holes and a self-aligning roller bearing supporting.Power passes to eccentric bushing 11 by input shaft 3 by flat key, when input shaft 3 rotations, promotes identical two planet halogen wheel, 15,151 motions that are 180 ° mutually of technical parameter by the capacity eccentric bearing on the eccentric bushing 11 16.The rolling star-wheel is by many eccentric spider gear shafts 10 and be contained in the lining 17 at its two ends and the antifriction-bearing box 27 on the lining combines, many eccentric spider gear shafts 10 run through respectively that the eccentric spider gear shaft axis holes 30 of several concentric spacing well-distributeds connect two planetary wheels on the planetary wheel, and many eccentric spider gear shafts respectively with each axis hole in 12 sockets of star-wheel bearing; Antifriction-bearing box 27 on the eccentric spider gear shaft two ends lining 17 is sleeved on by left step disk 19, right step disk 9, bolster 18 and is fastenedly connected in the pinion carrier bearing hole that forms, many bolsters 18 run through respectively that several concentric spacing well-distributed bolster axis holes 29 connect left and right step disk on the planetary wheel, and bolster does not contact with the bolster axis hole.Because pinion carrier is fixedly attached in left support abutment 25, the right support abutment 5 by flat key 20, anchor shaft 21, hollow shaft 6, so planetary wheel 15 is made revolution motion and promote the rolling star-wheel to make spinning motion under the combined action of rolling star-wheel and eccentric bushing 11.Planetary wheel 15 and inner gear 13 engagements, and inner gear 13 connects by junction of the edges of two sheets of paper pin 14 with barrel 22, barrel 22 connects with right end cap 8 and left end cap 23 bolt ups, be supported on hollow shaft 6 and the anchor shaft 21 by two self-aligning roller bearings 24, thereby the rotation of inner gear 13 has driven the rotation of barrel 22.

All adopt double oil seal in bearing gland 7 in this example on the left and right end cap and the little gland 4 on the hollow shaft, effectively prevent to ooze, leakage of oil.Self-aligning roller bearing 24 select the design of having satisfied high-power cylinder for use.Abat-vent 26 on anchor shaft 21 axle heads is communicated to barrel 22 inner chambers with circuitous air flue 28 in the anchor shaft 21, and the particular design of circuitous air flue has guaranteed to rise the air pressure unanimity in the barrel, prevented again from 26 mouthfuls of abat-vents ooze, leakage of oil.
