Abstract
The utility model discloses a speed changing box of a mini-tiller, comprising an input shaft, an output shaft and a transmission device, wherein the input shaft and the output shaft are arranged on a chassis in parallel, and the transmission device transfers power from the input shaft to the output shaft. The transmission device is a gear set with shift, and the gears of the gear set are straight teeth or helical teeth which are axially parallel with the input shaft and the output shaft. As the transmission device has compact structure, the chassis can be made into an integral machine shell structure. The input shaft and the output shaft are arranged at two heads of a machine shell, and the gear set is installed in the machine shell. The machine shell can be made in a stamping mode. The speed changing box of the mini-tiller adopts the integral machine shell structure and integrates the functions of walking and speed changing on a box body. The speed changing box of the mini-tiller realizes the integration of the two functions of speed changing and walking by a series of gear sets and solves the problem that the weight of the traditional speed changing box is overweight. With low working noise and strong anti-impact force, the speed changing box of the mini-tiller can be competent at the work on a variety of complex work place and environment.
Description
(1) technical field:
The utility model relates to diesel engine or the petrol engine microtilling machine transmission device as power, is the capable change of a kind of microtilling machine case specifically.
(2) background technique:
The capable change of present known microtilling machine case mainly contains two types:
One class be gearbox and walking case separately, engine running drives gearbox gear and rotates, and in gearbox (gearshift) change speed and direction as required, drive the output shaft rotation by walking two groups of bevel gears of case and connecting rod then.This class type casing adopts casting to form, preponderance, and volume is excessive, adopts more bevel gear set, so the bad adjustment of gear clearance, and noise is bigger.
Another kind of is to give output shaft by chain transmission power, and this class casing adopts casting to form, preponderance, and chain transmission has directivity, so this class type all do not design reverse gear, and chain transmission impact resistance power is poor, so this class type working environment is had relatively high expectations.
(3) model utility content:
At the deficiency of existing microtilling machine transmission device, the utility model provides a kind of and collects speed change and walking function is the capable change of the microtilling machine case of one.
Can realize the capable change of the microtilling machine case of above-mentioned purpose, be included in parallel and input shaft and the output shaft put on the cabinet, and the transmission device of transferring power between the input shaft, output shaft, different is described transmission device is gear train that can conversion gear (changing output speed and direction), for making the gear train compact structure, used gear is axially straight-tooth or the helical teeth parallel with output shaft with input shaft; Because the transmission structures compactness, the used cabinet of the utility model can adopt the single-piece frame structure, and input shaft and output shaft are arranged in two of casing, and gear train then is installed in the casing.
The gear of transmission device described in the utility model can equally with traditional microtilling machine gearbox design neutral equally, reverse gear and two forward gears.
Can produce casing described in the utility model by stamping forming processing mode with plate.The utility model structure is comparatively compact, and the distance between described input shaft and the output shaft is 300mm～400mm, and distance is 140mm～160mm between the bearing position of described input shaft (2), and distance is 90mm～100mm between the bearing position of described output shaft (3); Described single-piece frame length is 460mm～500mm.
Advantage of the present utility model:
1, the capable change of the utility model microtilling machine box body adopts whole impact briquetting shell, the function of walking and speed change is integrated in a row becomes case, realize speed change and the unification of two functions of walking by the series of gears group, solved the problem of traditional gearbox and walking case preponderance.
2, the utility model adopts the all-gear drive mode, has avoided the defective of traditional kind of drive, and operating noise is little, and impact resistance power is strong, can be competent at a job in the work-yard of various complexity and environment.
(4) description of drawings:
Fig. 1 is the structural representation of a kind of mode of execution of the utility model.
Figure number sign: 1, cabinet; 2, input shaft; 3, output shaft; 4, gear train; 5 gearshifts.
(5) embodiment:
The capable change of the utility model microtilling machine case as shown in Figure 1, constitute by cabinet 1, input shaft 2, output shaft 3 and gear train 4, cabinet 1 is a single-piece frame, impact briquetting part by two hemihedry is formed by connecting with screw, the two ends of casing are provided with the bearing position of input shaft 2 and output shaft 3 respectively, input shaft 2 and output shaft 3 are installed on the bearing position and are parallel to each other, it between input shaft 2 and the output shaft 3 transmission device that connects both, the gear train 4 of transmission device for shifting gears, all gears of gear train 4 are straight-tooth.
As shown in Figure 1, gear train 4 is three grades of axially parallel with input shaft 2 and output shaft 3 transmissions, be respectively double reduction transmission and the transmission of one-level constant speed, it is other that the gearshift 5 of gear train 4 is located at input shaft 2, goes up a shift fork that moves by gearshift axle parallel with input shaft 2 and gearshift axle and constitute; Four coaxial gears that are connected are arranged on the driving shaft of the first order gearing down of gear train 4, be respectively reverse gear, driving gear, the first forward gear gear and the second forward gear gear from left to right; Be one can axially movable duplicate gear on the input shaft 2, duplicate gear be stirred by shift fork, stirs duplicate gear when mobile from left to right when shift fork, can form four gears outputs of output shaft 3:
1, reverse gear, this moment, the left side gear of duplicate gear meshed by intermediate gear and reverse gear.
2, neutral, this moment, the left side gear of duplicate gear broke away from intermediate gear, and the right side gear of duplicate gear is crossed driving gear.
3, first forward gear, the right side gear and the first forward gear gear engagement of duplicate gear at this moment.
4, second forward gear, this moment, the right side gear and the first forward gear gear of duplicate gear broke away from, with the second forward gear gear engagement.
Distance between described input shaft 2 and the output shaft 3 is 300mm～400mm, and described single-piece frame length is 460mm～500mm; Distance is 140mm～160mm between the bearing position of described input shaft 2; Distance is 90mm～100mm between the bearing position of described output shaft 3.
