Description
Technical field,
The utility model relates to a kind of speed reduction gearing, especially a kind of be applicable to the car hosit hoisting mechanism put the speed reduction gearing that hoists soon.
Background technology
Reel-reductor assembly is to guarantee the reliable and secure critical component that carries out of its elevator operation on the car hosit, is determining the quality of its elevator transaction capabilities to a great extent.Reel-reductor the assembly that on car hosit, uses at present; Adopting the permanent mode of captiveing joint between the power output element (like the major planets frame) that is built in the reductor in the reel and the reel, promptly no matter which kind of operation operating mode hoisting crane is in, all is that reductor drives reel and rotates; Therefore there is following problem: when in underloading even zero load, transfer in the stroke of suspension hook; Can only drive the reel revolution through reductor by HM Hydraulic Motor, the lowering velocity that this has not only greatly limited suspension hook has influenced operating efficiency; But also can cause the unnecessary energy resource consumption and the wearing and tearing of speed reduction gearing, and further caused the heating of hydraulic efficiency pressure system.The drg of the reel-reductor assembly that uses at present in addition and reductor are integrated in one and are built among the reel, both have been unfavorable for the diffusing consumption of drag friction heat, also are unfavorable for the dismounting maintenance.
Summary of the invention
Technical matters: the purpose of the utility model is the deficiency that overcomes in the prior art, provides that a kind of compact conformation is simple, easy accessibility, result of use are good puts the speed reduction gearing that hoists soon.
Technical scheme: the utility model put the speed reduction gearing that hoists soon; Mainly constitute by drg, power-transfer clutch, drive sleeve, supporting base, adapter shaft, bearing, reel, reductor, spline housing, major planets frame and swivel coupling; Described reductor is a secondary planetary gear reducing mechanism; Integral body is built in the endoporus of reel through bearings at both ends, and spline housing is located at the right-hand member of reductor, is connected with the HM Hydraulic Motor axle through spline housing; Major planets is erected at the left end of reductor, is connected with the right-hand member castellated shaft of adapter shaft through spline; Described drive sleeve is that the center is processed with axially extending bore, both ends are the columnar structured of different-diameter; Columnar structured left part cylinder bore area is the frictional engagement face of power-transfer clutch shoe plate, and its left part cylinder external cylindrical surface is the brake drag effect face of drg brake collar; Drive sleeve is fixed together through screw and bearing and reel, and is bearing on the supporting base that is fixedly linked with frame through two bearings; Be bearing in the endoporus of drive sleeve through bearing in the middle of the described adapter shaft, be processed with internal oil channel on the left side vertically, and be connected with swivel coupling, adapter shaft is fixed together through flat key and power-transfer clutch.
Described power-transfer clutch is that oil pressure combines the shoe type power-transfer clutch; Described drg is the normally closed external contracting drum brake that oil pressure is opened.
Beneficial effect: because the power output element major planets frame of reductor is connected with reel through adapter shaft, power-transfer clutch, drive sleeve etc.; Can realize being connected and separating of reductor and reel at an easy rate according to the needs of the operation operating mode that hoists; Transfer the operating efficiency of suspension hook when improving zero load or underloading, avoid unnecessary energy consumption and abrasion; Adapter shaft is connected through spline with the major planets frame of reductor, is convenient to dismounting; Drg is arranged at the outside, is convenient to the reasonable Arrangement of structure, and under the prerequisite that guarantees braking reliability, effectively reduces the braking contact stress, improves service life.It is simple and reasonable, and reliability is high, and dismounting is convenient, can realize fast playing function, has practicality widely.
Description of drawings
Fig. 1 is the speed reduction gearing constructional drawing that hoists of the utility model.
Among the figure: the 1-drg; The 2-power-transfer clutch; The 3-drive sleeve; The 4-supporting base; The 5-adapter shaft; The 6-bearing; The 7-reel; The 8-reductor; The 9-spline housing; 10-major planets frame; The 11-swivel coupling.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further description:
As shown in Figure 1, the speed reduction gearing that hoists of putting soon of the utility model mainly is made up of drg 1, power-transfer clutch 2, drive sleeve 3, supporting base 4, adapter shaft 5, bearing 6, reel 7, reductor 8, spline housing 9, major planets frame 10 and swivel coupling 11.Reductor 8 is a secondary planetary gear reducing mechanism; Integral body is built in the endoporus of reel 7 through bearings at both ends; Its right-hand member is connected with the HM Hydraulic Motor axle through spline housing 9, and the power output element major planets frame 10 of its left end is connected with the right-hand member castellated shaft of adapter shaft 5 through spline.Drive sleeve 3 is for the center is processed with axially extending bore, both ends are the columnar structured of different-diameter, wherein the left part cylinder bore area and the external cylindrical surface frictional engagement face that is respectively power-transfer clutch 2 shoe plates and the brake drag effect face of drg 1 brake collar; Drive sleeve 3 is fixed together with reel 7 through screw and bearing 6, and is bearing on the supporting base 4 that is fixedly linked with frame through two bearings.Be bearing in the endoporus of drive sleeve 3 through bearing in the middle of the adapter shaft 5, be processed with internal oil channel on the left side vertically, and be connected with quick coupling, left part is fixed together through the driving part of flat key and power-transfer clutch 2; Power-transfer clutch 2 combines shoe type power-transfer clutch, the normally closed external contracting drum brake that drg 1 is opened for oil pressure for oil pressure.
Its working process and principle: when needs carry out elevator or band when putting operation; Pressure oil is introduced in the operating cylinder of drg 1; And through the swivel coupling 11 of adapter shaft 5 left parts pressure oil is introduced in the operating cylinder of power-transfer clutch 2 simultaneously, the braking force of drg 1 is removed, power-transfer clutch 2 is combined; Adapter shaft 5 and drive sleeve 3 are lumped together through friction knot, the power output element major planets frame 10 of reductor is fixed together with reel 7.When need zero load or underloading are transferred suspension hook, only pressure oil is introduced in the operating cylinder of drg 1, the braking force of drg 1 is removed; And with the introducing of the oil in power-transfer clutch 2 operating cylinders fuel tank; Power-transfer clutch 2 separates, and adapter shaft 5 is thrown off with drive sleeve 3 fully be connected, and at this moment reel is in the free floating state; Suspension hook relies on self gravitation and steel rope to drive the reel twirl, realizes transferring fast of suspension hook.Be positioned the pressure oil in drg 1 operating cylinder to be introduced fuel tank when aerial when need make the weight that hoists or unloaded suspension hook, under the spring force effect, make the brake collar frictionally embrace drive sleeve 3, make reel 7 fixed.
