Abstract
The utility model discloses an agricultural machinery transmission assembly which comprises a transmission portion and a gear-shift portion. According to the transmission portion, an input shaft gear assembly is connected with an input shaft through splines. An output shaft first-gear gear, an output shaft second-gear gear and a bevel gear are connected with an output shaft through splines. Gears of the input shaft gear assembly are respectively matched with the output shaft first-gear gear and the output shaft second-gear gear in size. According to the gear-shift portion, a gear-shift block and a shifting fork are arranged on a gear-shift shaft through fixing pins, a gear-shift rocker arm is connected with the gear-shift block, and a self-lock steel ball and a self-lock spring are pressed on the gear-shift shaft and matched with a self-lock groove in the gear-shift shaft. The agricultural machinery transmission assembly is simple in structure, gear shift is easy, and a gear-shift function can be achieved without the need of opening a box body.
Description
Technical field
The utility model belongs to agricultural machine speed changer field, particularly a kind of agricultural machinery transmission assembly device.
Background technique
More domestic agricultural machinery speed changer output speed standards have 540r/m, 720r/m and 1100r/m, this is the versatility of the agricultural equipment of restriction greatly, the most of coupling gear that changes of imitative Japan that adopts of the gearshift mechanism of agricultural machinery industry employing is at present shifted gears, this gear changing mode is loaded down with trivial details length consuming time but also need open casing not only, has greatly reduced working efficiency.
The model utility content
It is a kind of simple in structure that the purpose of this utility model is to provide, and gearshift is simple and without the agricultural machinery transmission assembly of opening casing and just can realize gearshift function.
The technical solution that realizes the utility model purpose is:
A kind of agricultural machinery transmission assembly, comprise transmission and gear shift two-part, described drive part: input shaft gear component is connected with input shaft by spline, one grade of gear of output shaft, the output shaft intermediate gear is connected with output shaft by spline with bevel gear, the gear of input shaft gear component matches with one grade of gear of output shaft and output shaft intermediate gear size respectively, described gearshift part: shift block, shift fork is arranged on shifting shaft by fixing pin, gear-shifting rocker arm is connected with shift block, the self-locking steel ball, the self-locking spring compressing is on shifting shaft, with the self-locking grooves on shifting shaft, match.
The utility model compared with prior art, its remarkable advantage:
The utility model utilizes the remote operation of gearshift mechanism to make gear shift efficient and convenient, and the dismounting of existing speed changer, can not effectively raise working efficiency and using scope, and simple in structure.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model agricultural machinery transmission assembly drive part.
Fig. 2 is the structural representation of the utility model agricultural machinery transmission assembly gearshift part.
Embodiment
As depicted in figs. 1 and 2:
A kind of agricultural machinery transmission assembly of the utility model, comprise transmission and gear shift two-part, described drive part: input shaft gear component 2 is connected with input shaft 1 by spline, can make shaftgear assembly 2 move left and right on input shaft 1, one grade of gear 4 of output shaft, output shaft intermediate gear 3 is connected with output shaft 5 by spline with bevel gear 6, the gear of input shaft gear component 2 matches with one grade of gear 4 of output shaft and output shaft intermediate gear 3 sizes respectively, described gearshift part: shift block 10, shift fork 12 is arranged on shifting shaft 7 by fixing pin, gear-shifting rocker arm 11 is connected with shift block 10, self-locking steel ball 8, self-locking spring 9 compressings are on shifting shaft 7, with the self-locking grooves on shifting shaft 7, match, realize self-locking by the self-locking grooves on shifting shaft 7, shift fork 12 is connected in the end of shifting shaft 7, near input shaft gear component 2, regulates shift block 10 by gear-shifting rocker arm and drives shift fork pushing shaft gear assembly 2 while moving and move, thereby realize gearshift function.
By shaking gear-shifting rocker arm 11 drive gearshifts fast 10, move left and right, after putting in place, engage a gear realizes self-locking by the self-locking grooves on self-locking steel ball 8 and shifting shaft 7, promote the movement of input shaft gear component 2 by the movement of shift block 10, input shaft gear component 2 can be meshed separately with one grade of gear 4 of output shaft or output shaft intermediate gear 3, realize the change of output speed.
