Abstract
The utility model relates to a universal joint with a large torque and a small turning diameter. The universal joint comprises a cross shaft and a bearing seat which are made of G20Cr2Ni4A materials, the cross shaft and the bearing seat are connected through a cross shaft bearing, the diameter of the cross shaft bearing is 28.06mm, and the cross shaft and the bearing seat are detachably connected. The universal joint has the advantages of being simple in structure, and original 20CrMnTi production materials are changed into the G20Cr2Ni4A materials so that the bearing capacity is increased, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of universal joint, relates in particular to a kind of universal joint of high pulling torque small turning diameter.
Background technique
Plain edition 7C universal joint Maximum Torque is 10700N.m at present, and tired moment of torsion is 4200N.m.On special automobile chassis, in the situation that swing diameter is restricted, plain edition 7C universal joint bearing capacity is low, and working life is also very short, can't satisfy need of production.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of universal joint of high pulling torque small turning diameter of simple in structure, long service life is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the universal joint of this high pulling torque small turning diameter, comprise cross axle and the bearing support made by the G20Cr2Ni4A material, described cross axle is connected cross shaft bearing with bearing support and connects, and described cross shaft bearing diameter is 28.06mm.
Preferably, described cross axle and bearing support are for removably connecting.
Compared with prior art, usefulness of the present utility model is: the gimbal structure of this high pulling torque small turning diameter is simple, produces material by original 20CrMnTi and becomes G20Cr2Ni4A, and bearing capacity increases, long service life.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the gimbal structure schematic representation of the utility model high pulling torque small turning diameter.
Among the figure: 1, cross axle; 2, bearing support; 3, cross shaft bearing.
Embodiment:
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail:
The universal joint of a kind of high pulling torque small turning diameter shown in Figure 1 comprises cross axle 1 and the bearing support 2 made by the G20Cr2Ni4A material, and described cross axle 1 is connected with bearing support by cross shaft bearing 3 connections, and described cross shaft bearing 3 diameter are 28.06mm.Described bearing support 2 keyways add the R1 chamfering, and quiet torsional test surpasses the tired torsional moment test of 15000N. and surpasses 7500N.m.
Described cross axle 1 and bearing support 2 are for removably connecting.
The gimbal structure of this high pulling torque small turning diameter is simple, produces material by original 20CrMnTi and becomes G20Cr2Ni4A, and bearing capacity increases, long service life.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
