Abstract
The invention discloses a support shaft capable of realizing two-way positioning of a winch drum. The support shaft is fixed to a rack; an adapter sleeve is arranged in the support shaft, and an axial retainer ring on the adapter sleeve is used for axially positioning; a bearing arranged between the support shaft and the drum is arranged in a bearing seat in the drum; the bearing seat and the drum are fixed into a whole; the drum obtains an axial two-way positioning effect by the two-way positioning design of inner and outer rings of the bearing, and thereby, the bearing at the other end of the drum is in a floating state without being axially positioned; accordingly, the tolerance requirements of axial dimension chains of all transmission parts are reduced, a common bearing can be substituted with a self-lubricating composite sleeve, the integral design structure of a winch is reasonable and compact and the manufacture process requirements and cost are reduced.
Description
Technical field
The present invention relates to the capstan drum in a kind of weight-lifting equipment, the reel that refers in particular to a kind of winch can be realized the bolster of two-way location.
Background technology
Hydraulic pressure or electric winch are widely used in the various fixing and mobile lifting means, in general winch, as shown in Figure 1, existing reel 1 ' two ends be provided with the existing bearing 2 that is used for radial centering and axial location ', by the existing bolster 3 of existing bearing 2 ' supporting ' with screw retention existing frame 4 ' on.This for require the capstan drum external diameter as far as possible little, with reduced volume, expendable weight, will have problems with the specific (special) requirements that adapts to some portable weight-lifting equipment, because general-duty has the bigger thickness of bearing 2 ' radially all have now, to select for use the compound cover of self-lubricating to substitute plain bearing for this reason, and the compound cover bearing of self-lubricating does not have the effect of axial location, thereby has proposed the existing bolster 3 of capstan drum one end ' can realize the problem of axial two-way location.
Summary of the invention
Purpose of the present invention addresses the above problem exactly, proposes the bolster that a kind of capstan drum can be realized two-way location, with the design goal of realizing that the footpath may be little at the bottom of the capstan drum, makes lorry-mounted crane etc. to the as far as possible little requirement of joining winch requirement.
Purpose of the present invention is achieved through the following technical solutions:
A kind of capstan drum can be realized the bolster of two-way location, it comprises frame, with the fixing bolster of frame, support with bearing between this bolster and the reel, it is characterized in that being provided with in the described bolster sleeve by the shaft block ring axial location, bearing between bolster and the reel is located in the interior bearing seat of reel, this bearing seat and reel are fixed, described outside race is by the hole back-up ring axial location of takeing in the bearing seat and being embedded in bearing seat, and inner ring is by outer shoulder of sleeve and bolster middle part omoplate axial location.
Described bearing seat and reel fixedly be with both faying faces be provided with a plurality of circumference uniform distributions, junction of the edges of two sheets of paper bonded assembly holding screw is fixed as one.
Compared with prior art, bolster of the present invention is realized axial two-way location by the combination that sleeve and shaft block ring add head bearing and bearing seat, thereby make reel obtain the effect of axial two-way location, but the other end is free floating just, and this structure not only can adopt the compound cover of self-lubricating to substitute bearing, directly reduces at the bottom of can making reel, and can reduce the tolerance of each driving parts axial dimension chain, help reducing manufacture process requirement and cost, it is rational in infrastructure, compactness.

Among the figure 1, reel, 2, bearing seat, 3, bearing, 4, the hole back-up ring, 5., bolster, 6, sleeve, 7, shaft block ring, 8, screw, 9, holding screw, 10, frame.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is remake and to specify.
Capstan drum of the present invention can be realized the bolster of two-way location, as shown in Figure 2, comprise a frame 10, bolster 5 is fixed on the frame with screw 8, be provided with the sleeve 6 that matches with its endoporus in the bolster, make axial location with the axial back-up ring 7 that is embedded on sleeve, be provided with bearing seat 2 in the reel 1 of coiling cable wire, both are fixed as one by a plurality of circumference uniform distributions on the faying face and junction of the edges of two sheets of paper bonded assembly holding screw 9, support with bearing 3 between described bearing seat 2 and the bolster 5, the outer ring of this bearing is made axial location with the hole of takeing in the bearing seat 2 and being embedded in bearing seat with back-up ring 4, and bearing cone is made axial location with sleeve 6 outer shoulders and bolster 5 middle part omoplates.The two-way location design of bearing 3 inside and outside circles makes bolster 5 obtain the effect of axial two-way location, makes capstan drum 1 also obtain the effect of axial two-way location then, thereby has improved reel reliability of operation and safety, and it is rational in infrastructure, compact.Because reel one end is by axial two-way location, but the other end is free floating just, this structure not only can adopt the compound cover of self-lubricating to substitute bearing, therefore the footpath is very little at the bottom of can making reel, and can reduce the tolerance of the axial dimension chain of each driving parts, help making institutes such as lorry-mounted crane to join the as far as possible little requirement of winch requirement, help reducing manufacture process requirement and cost.
Capstan drum realizes that with the flow distributor on the left side input hydraulic pressure oil drives HM Hydraulic Motor work done outputting power, drives reel 1 through bearing seat 2 and does positive and negative rotation, makes the cable wire retractable that is wound on the reel reach the purpose of lifting or traction weight.
