Specific embodiment 1：
Two output shafts of twin-screw Bulking Machine gear-box, output long axis, output short axle require to be constant speed drive（Rotating ratio
It is 1:1）, and because the torsion of transmission is bigger, spline is processed on axis to carry out the transmission of power, and short in output long axis, output
There are certain phase requirements on axis spline, as shown in Figure 3, it is desirable that 7 middle part of tooth top of spline aligns, the internal drive of gear-box
Be the transmission by gear, main pass order is as follows, the 6th gear engaged with first gear after drive output long axis and
Second gear rotates, and by second gear and the 5th gear engaged transmission, drives the 4th gear movement, the 4th gear and third tooth
Wheel engagement drives output short axle movement.By the design of certain gear ratio, ensure output long axis and output short axle constant speed fortune
Turn, and during ensureing rotation, two output shafts have certain phase angle to require.
Specifically used method is as follows：
Output long axis is divided into output front axle and output rear axle now, and exports front axle and two external splines is set, the number of teeth is not
Together, respectively m, n tooth, m, n numerical value is different, and at this moment the phase difference of front and back two splines is：360°/m-360°/n=360°(n-m)/
(m*n)。
Work as m, when n is certain numerical value, the phase difference of two splines is very little, such as:n=m+1.
Such as：When m=36, n=37（The two prime number each other）, at this moment：Export two spline phase difference=360 ° of front axle（37-
36）/(36*37)=0.27°.
Phase angle method of adjustment is as follows：
Step 1：Tooth 31A, the second label tooth 32A are marked in the 4th gear of jackshaft and each label first of the 5th gear；
Step 2：So that one tooth of second gear and second is marked tooth engagement, makes in output short axle each of on third gear
Tooth is fitted with the first label tooth, finds a suitable tooth respectively, ensures output long axis and phase in the middle part of output short axle tooth top
It is aligned in certain margin of tolerance.
Step 3：It cannot such as meet the requirements, output front axle be extracted from output rear axle, after rotating a spline tooth, again
After being installed on output rear axle, ensure to align in certain margin of tolerance in the middle part of output long axis and output short axle tooth top.
Step 4：Step 2,3 are repeated, ensure to align in certain margin of tolerance in the middle part of output long axis and output short axle tooth top.
It is adjusted if it is necessary, can also increase step 5, phase difference adjusting is carried out to two meshing points and a spline.
Step 5：Another tooth of second gear and the second label tooth engagement are readjusted, and makes third gear in output short axle
On each tooth, be fitted respectively at the first label tooth, find a suitable tooth, ensure output long axis and output short axle tooth
Top middle part aligns in certain margin of tolerance.
It is adjusted, is had the following advantages by this scheme：
1, working strength reduces, efficient（Spline adjustment is opposite simple with the adjustment of gear match point, convenient）.
2, it is opposite with two at adjust, by adjusting at three, ensure the precision higher of output short axle phase difference.
The above is only the preferred embodiment of the utility model, it should be pointed out that：For the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
