Description
Technical field
The utility model relates to tractor part applied technical field, is specifically related to a kind of transmission shaft end cover structure for tractor.
Background technique
Tractor is a kind of for drawing and driving Work machine to complete the self-propelled motor machine of every mobile operation, also can fix operation power, its by motor, transmission, walk, turn to, the system such as hydraulic suspension, Power output, electrical instrumentation, riding manipulation and traction or device form; Engine power passes to driving wheel through transmission system, and tractor is travelled, and in actual life, common is all the medium transmitted using balata belt as power, divides the tractors such as agricultural, industry and specific use by function and purposes; Wheeled, crawler, boat tractor and self propelled chassis etc. are divided by structure type.
According to statistics, within 2010, operate steadily in China's tractor market, present many new features, total industrial output value and income from sales reach 348.13 hundred million yuan and 400.23 hundred million yuan respectively, meanwhile, outlet delivery value continues to keep strong growth, and the domestic large and middle tractor market demand continues run at high level, but amplification eases up, demand continues to extend to high-power direction, continue to continue to rise with double-digit amplitude in little market of dragging, and on the other hand, the regional market demand is unbalanced, brand competition is growing more intense, the market concentration improves further, but, be far from reaching demand saturation degree compared with the agriculture developed countries and regions such as America and Europe, in addition, product structure performance backwardness is the ubiquitous problem of China's Tractor Products, technical merit need to improve, due to tractor work under bad environment (sleet, high temperature, moist etc.), so require higher for the component of its composition, as the end cover sealing structure of the transmission shaft for tractor, end cover sealing structure is by transmission shaft and the extraneous a kind of design of part carrying out sealing, traditional lid seal structure complex and to produce Raw consumption large, easily there is distortion after Long-Time Service simultaneously, fracture, this have impact on the working efficiency of tractor greatly and there is great potential safety hazard.
Therefore, based on the problems referred to above, the utility model provides a kind of transmission shaft end cover structure for tractor.
Model utility content
Model utility object: the purpose of this utility model provides a kind of transmission shaft end cover structure for tractor, solve that existing end cover sealing structure is complicated and to produce Raw consumption large, easily there is the problem of being out of shape, rupturing, by project organization, the saving raw materials of advantages of simple, and improve assembling after sealing tightness, stop security hidden trouble, be convenient to simultaneously install and demolition and maintenance.
Technological scheme: a kind of transmission shaft end cover structure for tractor, comprise end cap body, and be separately positioned on the positioning hole of end cap body two ends and symmetry, and be arranged on end cap body one end and be positioned at the restraining groove of positioning hole side, and be arranged on intrinsic first circular groove of end cap, the second circular groove and the 3rd circular groove, wherein, described end cap body one end and be set to semicircle draw-in groove between positioning hole, side is set to flat V-type draw-in groove.
The technical program, described end cap body, restraining groove, the first circular groove, the second circular groove and the 3rd circular groove are formed in one structure.
The technical program, described end cap body one end diameter is greater than the other end.
The technical program, the diameter of described first circular groove, the second circular groove and the 3rd circular groove increases progressively successively.
Compared with prior art, the beneficial effect of a kind of transmission shaft end cover structure for tractor of the present utility model is: 1, its rational in infrastructure simple, be convenient to install and safeguard, save raw materials; 2, during assembling; the semicircle draw-in groove utilizing end cap body end and side to arrange, flat V-type draw-in groove snap on fixing frame for transmission shaft; relocate hole and restraining groove carries out fastening; inner drive shafts carries out seal protection respectively by the first circular groove, the second circular groove and the 3rd circular groove; simultaneously integrated agent structure, is convenient to production and processing, not yielding and fracture and good seal.Simultaneously the utility model cost of production low, easily promote.
Accompanying drawing explanation
Fig. 1 is the plan view of a kind of transmission shaft end cover structure for tractor of the present utility model;
Fig. 2 is the worm's eye view of a kind of transmission shaft end cover structure for tractor of the present utility model;
Wherein, in figure, sequence number is as follows: 1-end cap body, 2-positioning hole, 3-restraining groove, 4-first circular groove, 5-second circular groove, 6-the 3rd circular groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
A kind of transmission shaft end cover structure for tractor as depicted in figs. 1 and 2, comprise end cap body 1, and be separately positioned on end cap body 1 two ends and the positioning hole 2 of symmetry, and be arranged on end cap body 1 one end and be positioned at the restraining groove 3 of positioning hole 2 side, and the first circular groove 4, second circular groove 5 be arranged in end cap body 1 and the 3rd circular groove 6, wherein, end cap body 1 one end and be set to semicircle draw-in groove between positioning hole 2, side is set to flat V-type draw-in groove.
Further preferred, end cap body 1, restraining groove 3, first circular groove 4, second circular groove 5 and the 3rd circular groove 6 are formed in one structure, and be convenient to processing and install and not yielding, fracture, seal protection effect is better simultaneously; The diameter that end cap body 1 one end diameter is greater than the other end and the first circular groove 4, second circular groove 5 and the 3rd circular groove 6 increases progressively successively, and itself and transmission shaft scaffold structure are used in combination carries out sealing and assemble.
Embodiment
Further as shown in Figure 1, the positioning hole 2 of end cap body 1 end and restraining groove 3 is utilized to install fast, wherein positioned (preventing wrongly installed) by the semicircle draw-in groove identical with transmission shaft scaffold structure of end cap body 1 end and side, flat V-type draw-in groove, namely the first protruding circular groove 4, second circular groove 5 and the 3rd circular groove 6 are protected transmission shaft; The transmission shaft end cover structure of this structure; it is easy to assembly, rational in infrastructure, reduce production and processing raw material consumption and without distortion, phenomenon of rupture appearance, effectively transmission shaft is protected; improve the working efficiency of tractor, reduce the maintenance cost of user.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
