The present invention will be described in further detail below with reference to the embodiments of the drawings.
As shown in Figures 1 to 4, power takeoff of the present invention includes shell 1, and 1 inner support of shell has input shaft 2, transmission shaft 4 and defeated
Shaft 3, input shaft 2, transmission shaft 4 and the axis of output shaft 3 are parallel to each other, and input splined hole 23 are offered on input shaft 2, this is defeated
Enter splined hole 23 to be connected with the output shaft (not shown) of gearbox, input gear 21 is installed on the input shaft 2, is driven
Transition gear 41 is installed on axis 4, output gear 31 is installed on output shaft 3, that end that output shaft 3 stretches out shell 1 is provided with
Output end is fixedly connected with ring flange 6 on the output end, in order to be connect with external equipment (not shown), transition
Gear 41 is set between input gear 21 and output gear 31, and input gear 21, transition gear 41 and output gear 31 are successively
Engagement, input gear 21 and output gear 31 form speed increasing gear train.
Above-mentioned input shaft 2, transmission shaft 4 and output shaft 3 are supported on the shell 1 by second bearing.
Above-mentioned transition gear 41 is two, and the transmission shaft 4 for installing the transition gear 41 is also two, two transition gears
41 intermeshings further increase the distance of shaft centers between input shaft and output shaft.
As shown in figure 5, being provided with gearshift in shell 1, which includes be integrally formed on input shaft 2
One splined shaft 22 is integrally formed the second splined shaft 211 on input gear 21, the spline housing being connected on the first splined shaft 22
5 and the control mechanism that is slided along 22 axis direction of the first splined shaft of control spline housing 5, the first splined shaft 22 and the second spline
Axis 211 is coaxially disposed, and spline housing 5 couples the first splined shaft 22 and the second splined shaft 211 simultaneously under the action of control mechanism；It is empty
When gear, spline housing 5 only couples with the first splined shaft 22, at this point, gearbox only drives input shaft to rotate, input gear does not follow defeated
Enter axis rotation；When putting into gear, under the action of control mechanism, the axis direction along input shaft 2 slides spline housing 5, gradually makes spline
Set 5 is also realized with the second splined shaft 211 to be coupled, and gearbox drives input shaft rotation, passes through spline housing and the first splined shaft, second
Splined shaft couples simultaneously, and input gear is driven also input shaft to be followed to rotate, then drives output shaft rotation by gear pair, thus band
Dynamic external equipment work.
