Abstract
The invention discloses a big-power tractor rear power output shaft capable of being changed quickly and conveniently, and belongs to the technical field of agricultural wheel tractors. The rear power output shaft comprises a hollow shaft, a coupling shaft and a gland. The external surface of the middle part of the hollow shaft is provided with a ring of spline teeth. The inner wall of the left end of the hollow shaft is provided with a segment of a rectangular spline. The external surface of the right end of the coupling shaft is provided with an external spline matched with the spline of the hollow shaft. The right end of the coupling shaft is inserted into the left end of the hollow shaft. A ring of a boss is disposed at the left side of the rectangular spline on the coupling shaft. The coupling shaft is provided with a spline used for connecting a farm tool. The gland sleeves the coupling shaft and holds down the boss. The gland is fixed and connected to the left end of the hollow shaft. According to needs of coupling of the different farm tools, a tractor user can change the power output shaft without the need of dissembling the whole transmission assembly, namely, the tractor user only needs to dissemble the gland, pull the original coupling shaft out, change a coupling shaft provided with a corresponding connecting spline, and mount the gland. The shaft changing manner is simple, convenient, rapid and convenient for operation in the fields, thus increasing the working efficiency of the tractor in the fields.
Description
Technical field
The present invention relates to agricultural wheeled tractor, the big-power tractor rear power output shaft that specifically a kind of fast and easy is changed.
Background technique
The rear power output shaft spline specification major part of current domestic agricultural wheeled tractor is fixed, i.e. single spline specification output.In the time that tractor rear power output shaft connects different farm implements, need the splined mode of corresponding different size, but tractor conventional construction form, if change rear power output shaft, just need to take rear power output assembly apart, change very inconvenience, and replacement cost be higher.
There is portioned product to adopt flange plate as Placement in this position, but cannot ensure coaxality requirement, transmitting torque deficiency, and volume is larger; Also have part external product to adopt blind hole involute splines to connect, this spline can only adopt gear shaping processes, and involute splines calibration is difficult to ensure card, and work efficiency is low, and manufacture cost is higher.Above-mentioned two kinds of structures have all limited the development of power output after large power wheel tractor.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the big-power tractor rear power output shaft that a kind of fast and easy is changed.This device comprises joining shaft, hollow shaft and plays the gland of axially locating effect, tractor user connects needs according to different farm implements, do not need to take apart whole whole drive assembly and change pto＝power take-off, only need pull down gland, extract former joining shaft out, change again the joining shaft that has corresponding connecting key, then load onto gland.It is simple and efficient that this kind changes axle mode, is easy to field operation, thereby improve Field-working Tractor-implement efficiency.
The present invention is achieved by the following technical solution: the big-power tractor rear power output shaft that a kind of fast and easy is changed, comprises hollow shaft, joining shaft and gland; Described hollow shaft middle part outer surface is provided with a circle spline tooth; Hollow shaft left end inwall has one section of rectangular spline; Described joining shaft right-hand member outer surface is provided with the external splines coordinating with hollow shaft, and joining shaft right-hand member inserts hollow shaft left end; On joining shaft, rectangular spline left side is provided with a circle boss, and joining shaft has the spline for connecting farm implements; Described gland is sleeved on joining shaft and pushes down boss, and gland is fixedly connected on hollow shaft left end.
It is further: described hollow shaft left side has the equally distributed screw-threaded counterbore of a circle; On described gland, have the circle installation through hole corresponding with the screw-threaded counterbore of hollow shaft; Gland is fixed on hollow shaft left end by bolt, installation through hole and screw-threaded counterbore.
Between described bolt and gland, be provided with elastic washer.
The present invention can reach following beneficial effect:
1. the step of having simplified tractor replacing rear power output shaft, has reduced replacement cost.
2. joining shaft is convenient to remove quick, is convenient to maintenance, changes.
3. joining shaft adopts rectangular spline to connect with hollow shaft, path centering, and positioning precision is high, improves working life.
4. rectangular spline can be processed by general purpose machine tool, improves work efficiency, reduces manufacture cost.

Embodiment
Be below a specific embodiment of the present invention, existing the present invention will be further described by reference to the accompanying drawings.
As shown in Figure 1, the big-power tractor rear power output shaft that fast and easy is changed, it comprises and is arranged on the hollow shaft 5 of power outgoing position after tractor, the joining shaft 1 being connected with rectangular spline with hollow shaft 5 and for joining shaft 1 being axially fixed in to the gland 4 on hollow shaft 5.
As shown in Figures 2 and 3, hollow shaft 5 middle part outer surfaces are provided with the spline tooth 51 that a circle is connected with power output part after tractor; Hollow shaft 5 left end inwalls have one section of rectangular spline; Hollow shaft 5 left sides have the equally distributed screw-threaded counterbore 52 of a circle.
As shown in Figure 1, Figure 4 and Figure 5, joining shaft 1 right-hand member outer surface is provided with the external splines coordinating with hollow shaft 5, and joining shaft 1 right-hand member inserts hollow shaft 5 left ends; On joining shaft 1, rectangular spline left side is provided with a circle boss 11, and joining shaft 1 has the spline for connecting farm implements.
As shown in Fig. 1 and Fig. 6, on gland 4, have the circle installation through hole 41 corresponding with the screw-threaded counterbore 52 of hollow shaft 5; Gland 4 is sleeved on joining shaft 1 and pushes down boss 11, and gland 4 is fixed on hollow shaft 5 left ends by bolt 2, installation through hole 41 and screw-threaded counterbore 52.Between bolt 2 and gland 4, be provided with elastic washer 3.
