Power tractor pto after changing device

Power tractor pto after changing is 2019 - 11 - 14 webber Zhang Tijun ( Xuzhou kyle agricultural equipment co. , LTD. ) Abstract: this paper tells the story of high-power tractor pto after the status quo at home and abroad, and introduces a fast and accurate replacement after the tractor pto device technology solutions. Key words: power tractor; The power output shaft; Splined coupling of xuzhou kyle agricultural equipment co. , LTD. Is a high and new technology enterprise, the company is devoted to the r&d and manufacturing of the tractor. Its product is different from traditional tractor, it adopts modular design, unit layout, by diesel engine, transmission, transfer case, the middle box, the power transfer out final drive box, etc. An installation are introduced in this paper after the final drive box on the power output shaft quick changing device. A, the present situation of the tractor pto after structure at present, the domestic agricultural wheeled tractor pto after spline specification mostly fixed, the single spline specification output. When the tractor pto after connecting different tools, need corresponding different specifications of the spline connection way. Because of the tractor to the traditional structure form, however, to change the power output shaft, you need to open power output after assembly, change extremely inconvenient, and replacement of the high cost. So in this structure has some products use flange as a mode of connection, but cannot assure alignment requirements, torque is insufficient, and large size. Some foreign products using blind hole involute spline connection, the spline gear shaping processing technology is the only method to be adopted, involute spline indexing is difficult to guarantee, machining efficiency is low, the manufacturing cost is higher, is not suitable for our country agricultural machinery manufacturing existing conditions. The above both structure restricts the development of high-power wheel tractors in China after the development of the power output. Second, high-power tractor pto after changing device in order to solve the technical problems, this article provides a fast and accurate replacement after the tractor power output shaft of the device. This device including the connecting shaft, hollow shaft, and the function of axial positioning gland, tractor user according to the needs of different tools connection, do not need to open the final drive assembly to replace the power output shaft, only need to press down the cover, take out the connecting shaft replacement, gland on reload. This way in shaft is easy, easy to operation field, thus improve the efficiency of the tractor field work. This device is realized through the following technical scheme: high-power tractor pto after changing device as shown, it includes the connecting shaft 1, fastening components 2, 3, 4, gland hollow shaft 5. Is characterized by the connecting shaft is 1 to 5 the hollow shaft radial through rectangular spline connection, the path centering, hollow shaft 5 internal spline can use wire-cutting processing, batch production can be used after molding broach processing, heat treatment after grinding path, the connecting shaft 1 to match the hollow shaft 5 by the spline spline hob processing, heat treatment after grinding side key, key bottom; The connecting shaft axial positioning is 1 and the hollow shaft 5 through the socket head bolts fastening components 2, elastic washer 3 and gland 4. Three, the conclusion of this design can achieve the following results: 1. Simplify the tractor pto steps after replacement, reduces the replacement cost. 2. The connecting shaft out fast and convenient, easy to repair and replacement. 3. The connecting shaft and the hollow shaft adopts rectangle spline coupling, path centering, high positioning accuracy, improve the service life. 4. Spline machining using general machine tools, improve processing efficiency, reduce manufacturing cost. Source: the use and maintenance of agricultural machinery 2015, 3
