Abstract
The utility model discloses a speed reducer arranged in the belt pulley with few teeth difference. The input shaft 1 of the speed reducer is arranged in a hollow support shaft 5. The utility model is characterized in that a belt pulley 3 and the annular gear of the speed reducer form integration, and the whole body is installed on the both sides of a hoist housing 4 through the fixing support 2 of the support shaft. The end of the input shaft 1 of the speed reducer is provided with an anti-non-return device which is also used as a bearing. The speed reducer is arranged in the hoist. The utility model has the advantages of compact structure and high stability, realizes an input motive power with high rotational frequency and small torque, and reduces the lateral pulling force brought by the motive power to the hoist. Besides, the utility model can realize complete sealing and belt driving connection with power source and the input shaft, and moderates the effect to power source brought by the impact of the hoist.
Description
The utility model relates to a kind of reduction gear apparatus, places the few tooth difference reductor in the belt pulley.
At present, need the employed gig of industry of little bulk of vertical-lift or granular material, reductor wherein all is installed in outside the belt pulley, be connected with the belt pulley main shaft by coupler or sprocket wheel, like this, gig housing and power input shaft are inevitable gapped, cause poor sealing, dust leaks.Reductor power is output as slow speed of revolution, high pulling torque, and is fixed on a side of gig upper end, causes gig side direction pulling force excessively, and the harm complete machine is stable.Connect by coupler or sprocket wheel between reductor and the belt pulley, can not realize the check of belt pulley, must increase non-return device.
The purpose of this utility model provide a kind ofly place in the belt pulley, compact conformation, check are reliable, few tooth difference reductor of good stability.
The few tooth difference reductor that places in the belt pulley of the present utility model comprises few tooth difference deceleration transmission part, non-return device, belt pulley, belt pulley chock, bearing, fixed mount.The input shaft 1 of reductor places in the pivot shaft 5 of hollow, it is characterized in that the belt pulley 3 and the internally toothed annulus of reductor are integral, and integral body is installed in gig housing 4 both sides by pivot shaft fixed mount 2.Input shaft 1 one ends of reductor are equipped with the non-return device 8 of double as bearing.
Few tooth difference reductor is placed in the belt pulley of gig, and belt pulley double as internally toothed annulus is saved reducer shell, imput shaft, is reached coupled bearing, bearing seat, expendable weight; Reductor places the gig center, and both sides are stressed evenly, improved stability.Reductor and belt pulley are integral, and can realize the high revolution and the little moment of torsion of imput power, reduce the side direction pulling force of power to gig.This compact conformation, the part that contacts with the gig housing do not have relative motion, can realize sealing fully.Built-in reductor imput shaft can be accepted the power input of high rotating speed, little moment of torsion, can realize that therefore strap drive connects propulsion source and input shaft, relaxes the influence of the impact of gig to propulsion source.
Accompanying drawings embodiment:
Fig. 1 places scheme drawing in the gig for reductor
Fig. 2 is the constructional drawing that places reductor in the belt pulley
Fig. 3 is the belt pulley as internally toothed annulus
Fig. 4 is the belt pulley chock
Few tooth difference reductor that this places in the belt pulley comprises few tooth difference deceleration transmission part, non-return device, belt pulley, belt pulley chock, bearing, fixed mount.The input shaft 1 of reductor places in the pivot shaft 5 of hollow, it is characterized in that the belt pulley 3 and the internally toothed annulus of reductor are integral, and integral body is installed in gig housing 4 both sides by pivot shaft fixed mount 2.Belt pulley 3 does not have wheel hub, is annular arrangement, and the ring internal diameter is processed into the tooth 12 that is involute, and there is groove 13 the gear ring both sides, are used for fixing belt pulley chock 6.Chock 6 is bowl-shape, and big opening end 10 and osculum end 11 are arranged.Belt pulley 3 is fixed on the shaft shoulder of big opening end 10, and osculum end 11 joins by bearing 7 and pivot shaft 5,9.Pivot shaft 5 is a hollow, and axle 9 is an osed top, and axle head is square, and is fixed in the fixed mount 2 that is square frame shape, and is fixing with gig housing 4.Imput shaft 1 one ends are equipped with the non-return device 8 of double as bearing, and its outer ring is connected with the internal diameter key of pivot shaft 9.
