Abstract

The tractor postposition double-power output device mainly comprises: the gear box comprises a first shaft, a power output shaft, a sliding gear, a driven gear, a power output shaft, a shifting fork shaft, a separating handle and a spline sleeve, wherein the first shaft, the power output shaft, the sliding gear, the driven gear, the power output shaft, the shifting fork shaft, the separating handle and the spline sleeve are arranged on a shell of the. The first shaft arranged on the gearbox shell is connected with the power output shaft through the spline sleeve, the other end of the power output shaft is arranged on the gearbox shell, and the gearbox cover is sealed through bolts. The sliding gear installed on the power output shaft is meshed with the driven gear installed on the power output shaft. The power output shaft is combined and separated by shifting the sliding gear through the shifting fork shaft and the separating handle which are arranged on the gearbox shell. The device can select single-shaft power output or double-shaft power output according to the requirement of power output. Four rotating speeds of a double shaft can be output by utilizing high and low gears of the gearbox. Thereby enlarging the power output application range of the tractor and improving the range of the types of the matched farm implements of the tractor and the matched operation capability.

Description

The rearmounted double dynamical output unit of trac.

(1) technical field:

The utility model belongs to the trac. field, relates to the rearmounted double dynamical output unit of a kind of trac..

(2) background technology:

At present, domestic middle-size and small-size tractor dynamic power output commonly used has only a power take-off shaft, and rotating speed though can satisfy general job requirements, can not be realized takeoff output double-duty simultaneously between 540-1000 rev/min.When the main agricultural machinery and implement of tractor are worked,, can only provide by the additive incrementation dynamic host if need auxiliary power.Owing to lack the takeoff output of 2000 rev/mins of left and right sides scopes, when the high rotating speed tight duty operations of needs, just need on trac., increase the one-level speed increasing mechanism and just can realize, make the tractor structure complexity, the cost increase, and operate very inconvenient.

(3) utility model content:

The purpose of this utility model is to provide that a kind of functional reliability is good, simple in structure, cost is lower, uses the rearmounted double dynamical output unit of trac. easy to maintenance.

The technical solution of the utility model is: the rearmounted double dynamical output unit of trac. mainly comprises: be installed in one 2 of primary shaft 1, takeoff output, cliding gear 3, ring gear 4, power take-off shaft 5, declutch shift shaft 6, separation handle 7, spline housing 8 on the gear box casing, it is characterized in that: the primary shaft 1 that is installed on the gear box casing connects with one 2 of takeoff output by spline housing 8, one 2 other end of takeoff output is installed on the gear box casing, with bolt gear shift cover is sealed.The cliding gear 3 that is installed in one 2 of takeoff output is meshing with each other with the ring gear 4 that is installed in power take-off shaft 5.By be installed on the gear box casing declutch shift shaft 6 with separate handle 7 and stir combination that cliding gear 3 realizes power take-off shafts 5 and separate.

The utility model adopts the good effect that produces after the technique scheme to be: can select single shaft takeoff output or double-shaft power output according to the needs of takeoff output.Utilize the high and low retaining of change speed gear box can export four kinds of rotating speeds of twin shaft.Thereby enlarge the takeoff output range of use of trac., the supporting agricultural machinery and implement kind scope of trac. and supporting operation ability are improved.

Fig. 1 is the rearmounted double-shaft power output unit of a utility model trac. structural representation;

Fig. 2 is the rearmounted double-shaft power output unit of a utility model trac. A-A generalized section.

(5) specific embodiment:

As shown in Figure 1, the rearmounted double dynamical conveying device of trac. mainly by: primary shaft 1, one 2 of takeoff output, cliding gear 3, ring gear 4, power take-off shaft 5, declutch shift shaft 6, separate handle 7, spline housing 8 is formed.The primary shaft 1 that is installed on the gear box casing connects with one 2 of takeoff output by spline housing 8, and one 2 other end of takeoff output is installed on the gear box casing, with bolt gear shift cover is sealed.Being installed in the cliding gear 3 of exporting one 2 and the ring gear 4 that is installed in power take-off shaft 5 is meshing with each other.By be installed on the gear box casing declutch shift shaft 6 with separate handle 7 and stir combination that cliding gear 3 realizes power take-off shafts 5 and separate.

Primary shaft 1 is delivered to engine power on one 2 of the takeoff output by spline housing 8, is delivered on the power take-off shaft 5 by cliding gear 3, ring gear 4 again.By declutch shift shaft 6, separate combination that handle 7 realizes power take-off shafts 5 and separate, can select single shaft takeoff output or double-shaft power output according to the needs of takeoff output.Utilize the high to low gear of change speed gear box can export four kinds of rotating speeds of twin shaft.

During the trac. operation, be in low gear, one 2 of takeoff output can be exported 580 rev/mins of power by conter clockwise, and power take-off shaft 5 can be exported 700 rev/mins of power of cw; Be in high gear, one 2 of takeoff output can be exported 2300 rev/mins of power of conter clockwise, and power take-off shaft 5 can be exported 2700 rev/mins of power of cw.

Said structure can make the power takeoff point of trac. increase, and enlarges the takeoff output range of use of trac., and the supporting agricultural machinery and implement kind scope of trac. and supporting operation ability are improved.
