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 planetary wheels, 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.
