Description
Technical field
The utility model relates to tractor part applied technical field, is specifically related to a kind of end cover structure for tractor motive power output shaft.
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 cap of the pto＝power take-off for tractor, Power output hubcap is by transmission shaft and the extraneous a kind of design of part carrying out sealing, traditional Power output hubcap is complicated and the consumption of production Raw is 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 end cover structure for tractor motive power output shaft.
Model utility content
Model utility object: the purpose of this utility model provides a kind of end cover structure for tractor motive power output shaft, solve that existing Power output hubcap 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 end cover structure for tractor motive power output shaft, comprise end cap body, and the positioning hole be symmetricly set on end cap body, and be arranged on intrinsic first circular groove of end cap, and be arranged on the spacing hole of the first circular groove side, and the second circular groove be arranged on below the first circular groove, and be symmetricly set on the restraining groove of the first circular groove both sides, and be the positioning groove being arranged on end cap body one end, and be symmetricly set on the location aperture of positioning groove both sides.
The technical program, described positioning groove is U-shaped structure.
The technical program, one end diameter that described end cap body is provided with positioning groove is less than the other end.
The technical program, described first circular groove diameter is less than the second circular groove.
The technical program, described end cap body, the first circular groove, the second circular groove and positioning groove are formed in one structure.
Compared with prior art, the beneficial effect of a kind of end cover structure for tractor motive power output shaft of the present utility model is: 1, its rational in infrastructure simple, be convenient to install and safeguard, save raw materials; 2, during assembling; utilize positioning hole symmetrical on end cap body to coordinate with pto＝power take-off scaffold to locate; utilize the positioning groove of one end and scaffold to match to snap in; recycling location aperture is fixed; internal motivation axle carries out seal protection respectively by the first circular groove, the second 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 sectional view of a kind of end cover structure for tractor motive power output shaft of the present utility model;
Fig. 2 is the elevational view of a kind of end cover structure for tractor motive power output shaft of the present utility model;
Wherein, in figure, sequence number is as follows: 1-end cap body, 2-positioning hole, 3-first circular groove, 4-second circular groove, 5-spacing hole, 6-restraining groove, 7-positioning groove, 8-locate aperture.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
A kind of end cover structure for tractor motive power output shaft as depicted in figs. 1 and 2, comprise end cap body 1, and the positioning hole 2 be symmetricly set on end cap body 1, and the first circular groove 3 be arranged in end cap body 1, and be arranged on the spacing hole 5 of the first circular groove 3 side, and the second circular groove 4 be arranged on below the first circular groove 3, and be symmetricly set on the restraining groove 6 of the first circular groove 4 both sides, and be the positioning groove 7 being arranged on end cap body 1 one end, and be symmetricly set on the location aperture 8 of positioning groove 7 both sides.
Further preferred, positioning groove 7 be U-shaped structure, is convenient to process and easy to assembly, firm; One end diameter that end cap body 1 is provided with positioning groove 7 is less than the other end, and itself and pto＝power take-off scaffold match; First circular groove 3 diameter is less than the second circular groove 4, for carrying out seal protection to the pto＝power take-off of different size; End cap body 1, first circular groove 3, second circular groove 4 and positioning groove 7 are formed in one structure, wear-resisting not yielding, long service life.
Embodiment
