Abstract
The utility model relates to a split lifting mechanism for planetary gears, which comprises a motor, an input transmission shaft, inner gear rings, sun wheels, planet wheels, a planet carrier and a drum. The motor is connected with the input transmission shaft through a spline sleeve, the spline sleeve is detachably installed on the input transmission shaft, the input transmission shaft is connected with a first sun wheel, the first sun wheel meshes with a first planet, the first sun wheel meshes with a first gear ring and is connected with a secondary sun wheel through a first planet carrier, the secondary sun wheel meshes with a secondary planet wheel, the secondary planet wheel meshes with a secondary inner gear ring and is connected with the secondary planet wheel, the secondary planet wheel is connected with and fixed on a brake, and the first inner gear ring and the secondary inner gear ring are respectively connected with the drum. Since the motor is connected with the input transmission shaft through the spline sleeve, remanufacturing of a complicate input transmission shaft is omitted, and the split lifting mechanism can be connected with various motors only through changing the spline groove, thereby saving materials greatly and improving working efficiency.
Description
Technical field
The utility model relates to a kind of lifting mechanism, is specifically related to a kind of lifting mechanism that is used for hoisting crane.
Background technology
At present, the transmission shaft in the crane hoisting mechanism all adopts one-piece construction, and hoisting crane is passed to lifting mechanism by transmission shaft with the power of motor.When the spline housing at two ends in the transmission shaft is identical, can realize by the technology of garland key; When the parameter of two ends spline housing not simultaneously, hold spline housing need adopt gear shaping technology to process greatly, processing time consuming effort not only, and be difficult for guaranteeing the concentricity at two ends.Popularization along with motor applications, the enterprise that produces motor is more and more, the type of attachment of motor is also varied, simultaneously, because the transmission shaft of lifting mechanism adopts one-piece construction, a kind of lifting mechanism can only select a kind of suitable motor connection to carry out power transmission according to the form of transmission shaft, and type of attachment is single, can not adjust the transfer motion power of motor, be difficult to realize the requirement of the multiple power that hoists.Because the influence of environment for use and service conditions, lifting mechanism is requirement also, and output torque is big, and load-carrying capacity is strong, reliable operation, but shortcomings such as existing crane hoisting mechanism is big because of volume, weight is big, structure is not compact, cost height more and more do not satisfy the needs of goliath.
The utility model content
The utility model is big at the volume that existing lifting mechanism exists, weight big, structure is not compact, cost is high and can only connect above-mentioned deficiencies such as a kind of motor, transferring power are single, a kind of compact conformation is provided, volume is little, cost is low and transferring power adjustable size, in light weight, and the split type planetary wheel lifting mechanism of reliable operation.
The technical solution of the utility model is: a kind of split type planetary wheel lifting mechanism, comprise motor, input shaft, internally toothed annulus, sun wheel, satellite gear, pinion carrier and reel, be connected by spline housing between motor and the input shaft, spline housing detachably is installed on the input shaft, input shaft is connected with first order sun wheel, first order sun wheel and the engagement of first order satellite gear, first order satellite gear and the engagement of first order internally toothed annulus, and be connected with second stage sun wheel by first order pinion carrier, second stage sun wheel and the engagement of second stage satellite gear, second stage satellite gear and the engagement of second stage internally toothed annulus, and be connected with second stage pinion carrier, second stage pinion carrier is connected with drg and is fixed on the drg, first order internally toothed annulus, second stage internally toothed annulus is connected with reel respectively;
Preferably, described first order pinion carrier and second stage pinion carrier all adopt the integral type cantilever beam structure;
Preferably, described first order pinion carrier and second stage pinion carrier all adopt simple beam structure.
The beneficial effects of the utility model are: the utility model motor is connected with input shaft by spline housing, can different motors is connected with input shaft by changing spline housing, thus the power of the mechanism that adjusts hoisting; Adopt the secondary planet transmission simultaneously, wherein, the one-level planet floats and connects, and secondary planet is rigidly connected, and during work, the final stage pinion carrier is fixed, and gear ring drives reel and rotates.The utility model compact conformation, propulsive effort is big, cost is low, good airproof performance, and transfer torque is big, in light weight, and reliable operation.The utility model no longer needs to make again complicated input shaft, only needs to change simple spline housing, can realize easily and being connected of various motors that saving in material has improved work efficiency greatly.
