It is bad, and stop can clutch at the end that needs to output power in clutch.Also have and removed the gear of output shaft using handle,
This mode is driven unstable, and easily makes gear wear.Both mode gearbox lifes can all be badly damaged, and after clutch
Input can not move alone with output end.
The content of the invention
Technical problem to be solved in the utility model is the defect for overcoming prior art, there is provided a kind of band manual clutch work(
The gear-box of energy.
In order to solve the above technical problems, the utility model provides a kind of gear-box with manual clutch function, including carry
The input shaft of input gear, the output shaft with output gear, the middle clutch shaft with middle clutch gear and for putting
Put and fix the mounting seat and case of above-mentioned axle, by the cooperation between gear, input shaft drive in the middle of clutch shaft centre from
Gear is closed so as to drive output shaft to realize transmission, it is characterized in that, it is respectively arranged at two ends with big self-lubricating in the middle clutch shaft
Axle sleeve and small self lubrication bearing, realize the high accuracy of radial fit；The middle clutch gear is provided with bearing chamber for installing
Bearing, the middle clutch shaft is provided with brake spring, is used to compress in the bearing in idler gear by the pretightning force of spring
Circle, the other end of bearing inner race is pressed in the shaft shoulder on clutch shaft, so as to compress middle clutch shaft so that middle clutch gear passes through
Bearing normal rotation, and middle clutch shaft is compressed by pretightning force and not rotated；The middle clutch shaft stretches out one end of case
Clutch lever is provided with, leans on center section setting step to carry out the separation point position of clutch lever on middle clutch shaft spacing；Institute
The bearing chamber in the middle of mounting seat is stated with stomata, prevents from producing vacuum during middle clutch shaft clutch, influence clutch；All teeth
Wheel has chamfering in the end of mutual clutch, and in flank profil end-beveling so that gear has guiding when engaging, engagement is steady, makes an uproar
Sound is low.
Further, the input gear is arranged on input shaft and output shaft by interference fit respectively with output gear
On, and linked by key.
Further, the input shaft is threaded with output shaft end, by nut screwing clamping, controls axial gap.
The beneficial effect that the utility model is reached：
Gear-box with manual clutch function of the present utility model, it is simple and compact for structure, make simple, it is easy to operate, make
With long lifespan, low cost is easy to maintenance.After the utility model is capable of achieving clutch, and separation under gear-box normal operating conditions
Input and output end can be rotated individually.
Brief description of the drawings
Fig. 1 is structural representation when gear train is engaged when clutch lever is located at initial position；
Fig. 2 is that clutch lever pulls out in the middle of during restraining position clutch gear with input gear/output gear disengagement
When schematic diagram.
In figure 1 is case, and 2 is mounting seat, and 3 is input shaft, and 4 is middle clutch shaft, and 5 is output shaft, and 6 is input tooth
Wheel, 7 is middle clutch gear, and 8 is output gear, and 9 is brake spring, and 10 is clutch lever, and 11 is small self lubrication bearing, and 12 are
Big self lubrication bearing, 13 is nut, and 14 is step.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As shown in figure 1, the gear-box with manual clutch function of the present utility model includes：Case 1, mounting seat 2, input 3,
It is middle clutch shaft 4, output shaft 5, input gear 6, middle clutch gear 7, output gear 8, brake spring 9, clutch lever 10, small
Self lubrication bearing 11, big self lubrication bearing 12, nut 13.When clutch lever 10 is located at initial position, by the pre- of brake spring 9
Clamp force compresses middle clutch gear 7, and the input shaft 3 drives input gear 6, by the band of middle clutch gear 7 being engaged with
Dynamic output gear 8, so that output shaft 5 is rotated, gear-box is in normal operating conditions.
As shown in Fig. 2 during normal work, clutch lever 10 is pulled out manually, middle clutch shaft 4 drives middle clutch tooth
Wheel 7 along axis direction move, when the step 14 on middle clutch shaft 4 is contacted with the bottom surface of case 1, middle clutch gear 7 and
Input gear 6, output gear 8 are disengaged, and input shaft 3 is realized being kept completely separate with output shaft 5, and input shaft 3 and output shaft 5
Realize individually rotating.When unclamp clutch lever 10 after, in the presence of the elastic force of brake spring 9, and due to input gear 6,
The engaging end of middle clutch gear 7 and output gear 8 is provided with chamfering, middle clutch gear 7 and input gear 6, output gear
