Abstract
The invention relates to an eccentric axle sleeve wheelset. The eccentric sleeve wheelset comprises a wheel axle, wherein a wheel is installed on the wheel axle through a key. The wheelset is characterized in that a first eccentric large axle sleeve and a second large axle sleeve are respectively installed on two sides of the wheel, the first eccentric large axle sleeve and the second eccentric large axle sleeve are respectively installed on the wheel axle through bearings; the inner diameter of the inner ring of each of the first eccentric large axle sleeve and the second eccentric large axle sleeve is B, the inner diameter of the circle to which the circle center of an edge flange hole belongs on each of the first eccentric large axle sleeve and the second eccentric large axle sleeve is A, a deviation value a exists between the central line of A and the central line of B; and steel seals are arranged on the first eccentric large axle sleeve and the second eccentric large axle sleeve. The axes of four wheelset of a trolley can be adjusted to on the same horizontal level so as to guarantee that four wheels on four corners of the vehicle can contact with the steel rail simultaneously, the condition that individual wheel is hung in the air is avoided, the trolley can stably and safety run on the steel rail.
Description
Technical field
The present invention relates to a kind of excentric sleeve wheel group, belong to logistics equipment technical field.
Background technology
Along with present Development of Logistics Industry, hoisting crane is employed more and more widely, and along with the development of modern industry, the requirement of people to the manufacture processing of hoisting crane, assembly precision is more and more higher, to improve its service life, to maintain easily maintenance.In order to meet the requirement of user, the car wheel group of present hoisting crane is mostly 45 ° of split type structure forms, although this structure assembly precision improves, but it is larger by trolley frame, gauge, the wheelspan of four wheel groups are larger, trolley frame wheel assembles the error after overall bore hole may be comparatively large, therefore possibly cannot ensure that axletree is in same level, causes individual wheel unsettled during wheel assembling.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of excentric sleeve wheel group is provided, guarantee the axle center of four the wheel groups adjusting dolly in same level, namely ensure that four wheels on dolly four angles can contact with rail simultaneously, there will not be individual wheel unsettled, to ensure dolly steady safe operation on rail.
According to technical scheme provided by the invention, described excentric sleeve wheel group, comprises axletree, by key installing wheel on axletree; It is characterized in that: install the first eccentric large shaft sleeve and the second eccentric large shaft sleeve respectively in the both sides of described wheel, the first eccentric large shaft sleeve and the second eccentric large shaft sleeve are arranged on axletree respectively by bearing; The internal diameter of described first eccentric large shaft sleeve and the second eccentric large shaft sleeve inner ring is B, and the internal diameter of place, the center of circle circle of the edge method flange aperture of the first eccentric large shaft sleeve and the second eccentric large shaft sleeve is there is deviate a between the line of centers of A, A and the line of centers of B.
Further, described first eccentric large shaft sleeve and the second eccentric large shaft sleeve arrange steel seal.
Further, described first eccentric large shaft sleeve and the second eccentric large shaft sleeve are fixed respectively by the first bolt and the first packing ring and trolley frame.
The present invention has the following advantages: (1) is originally bright simple and reliable for structure, easy to maintenance; (2) the present invention can adjust the level height in axletree axle center, to ensure that the axle center of four wheels is in same level.

Fig. 3 is the lateral plan of Fig. 2.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in FIG. 1 to 3: described excentric sleeve wheel group comprises axletree 1, the logical lid 3 of wheel 2, first, spacer 4, the second logical eccentric large shaft sleeve 6-1 of lid 5, first, the second eccentric large shaft sleeve 6-2, adjusting pad 7, stifle 8, first bolt 9, first packing ring 10, second bolt 11, second packing ring 12, bearing 13, first lubricating cup 14, second lubricating cup 15, key 16, J type oil sealing 17, felt collar oil sealing 18, threeway lid 19, steel seal 20 etc.
As shown in Figure 1, the present invention includes axletree 1, by key 16 installing wheel 2 on axletree 1, the both sides of wheel 2 install the first eccentric large shaft sleeve 6-1 and the second eccentric large shaft sleeve 6-2 respectively, and the first eccentric large shaft sleeve 6-1 and the second eccentric large shaft sleeve 6-2 is arranged on axletree 1 respectively by bearing 13; The arranged outside stifle 8 of described first eccentric large shaft sleeve 6-1, arranges adjusting pad 7 between stifle 8 and eccentric large shaft sleeve 6, the inner side of the first eccentric large shaft sleeve 6-1 arranges the second logical lid 5; The arranged outside first of described second eccentric large shaft sleeve 6-2 leads to lid 3, and the inner side of the second eccentric large shaft sleeve 6-2 arranges threeway lid 19; Described second logical lid 5 and between threeway lid 19 and axletree 1, spacer 4 is set, the second logical lid 5 and arrange between threeway lid 19 and spacer 4 that J type oil sealing 17, the first is logical arranges felt collar oil sealing 18 between lid 3 and axletree 1;
As shown in Figure 2 and Figure 3, the internal diameter of described first eccentric large shaft sleeve 6-1 and the second eccentric large shaft sleeve 6-2 inner ring is B, the internal diameter of place, the center of circle circle of the edge method flange aperture of the first eccentric large shaft sleeve 6-1 and the second eccentric large shaft sleeve 6-2 is have deviation a between the line of centers of A, A and the line of centers of B; Namely be the circle of diameter with A and take B as the round decentraction of diameter;
As shown in Figure 3, described first eccentric large shaft sleeve 6-1 and the second eccentric large shaft sleeve 6-2 arranges steel seal 20, so that as benchmark during install and adjust;
As shown in Figure 1, described first eccentric large shaft sleeve 6-1 and the second eccentric large shaft sleeve 6-2 fixes with trolley frame respectively by the first bolt 9 and the first packing ring 10; Described first logical lid 3 and the second eccentric large shaft sleeve 6-2 are connected and fixed by the second bolt 11 and the second packing ring 12;
