The power output shaft can be changed without detaching a whole final transmission assembly according to different agricultural tool connection needs by tractor users, only the pressing cover is detached, the original connection shaft is drew out, connection shafts with corresponding connection keys can be changed, and then the pressing cover is mounted. Therefore, the power output shaft is convenient and fast to change, and easy to operate in fields, and the field working efficiency of the tractors can be improved.
Description
Technical field
The utility model 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.When tractor rear power output shaft connects different farm implements, need the splined mode of corresponding different size, however 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.
In this position, have portioned product to adopt flange plate as Placement, but cannot guarantee coaxality requirement, transmitting torque is not enough, 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 big-power tractor rear power output shaft that the utility model provides a kind of fast and easy to change.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 utility model 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 for connecting the spline of 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 utility model 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 utility model, now by reference to the accompanying drawings the utility model be described further.
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 for connecting the spline of 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.
