The depth of parallelism.
Preferably, the two ends of the second transition axis are designed with distance collar.
By using technique scheme, distance collar is all set at the two ends of the second transition axis, on the one hand can ensure that the
Two depth of parallelisms fixing axle self, on the other hand control First Transition axle and the opposing parallel degree of the second transition axis, it is ensured that gear
Abrasion can be reduced in the running, improve efficiency, increase the service life.
Preferably, the first roller gear, the second roller gear, the 3rd roller gear, the 4th roller gear are all helical teeth circle
Stud wheel.
By using technique scheme, all gears all use helical gears, and helical gear is energy compared with spur gear
Enough improve the registration of engagement between gear, make gear drive steadily carry out, advantageously reduce noise.
Preferably, the diameter of the second roller gear is bigger than the first roller gear diameter, the diameter of the 4th roller gear ratio the
The diameter of three roller gears is big.
By using technique scheme, the second roller gear is the driving gear of the second transition axis, therefore the second cylinder
The diameter that gear is arranged is conducive to more greatly driving the second transition axis;In addition, this magnitude relationship compound reduction requirement.
Preferably, bearing is self-aligning roller bearing.
By using technique scheme, self-aligning roller bearing can bear radial load, also can bear either direction simultaneously
Axial load, therefore can resist helical gear axial thrust so that helical gear can smooth rotation;In addition, its regulation of mental activities
Can be good, energy compensating coaxial degree error, be conducive to keeping the stable relative position relation between each axle of decelerator.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As it is shown in figure 1, a kind of vertical shaft gear reducer, including casing 1, bevel gear shaft 2 is installed in casing 1, bores tooth
Wheel shaft 2 is provided with bevel gear set 3, and the output gear 31 of bevel gear set 3 is set on First Transition axle 4, output gear 31 and
The spline of one transition axis 4 is affixed, and the two ends of First Transition axle 4 are rotatably connected in the bearing 7 in casing 1, and First Transition axle 4
Being provided with spacer ring 9 at the bearing 7 of the output gear 31 of upper close bevel gear set 3, the other end is provided with distance collar 8 at bearing 7,
First roller gear 41 coaxially connected with First Transition axle 4 it is provided with at distance collar 8.
First roller gear 41 external toothing has the second roller gear 51, and the diameter of the second roller gear 51 is than the first cylinder
The diameter of gear 41 is big.Second roller gear 51 is set on the second transition axis 5, and the second transition axis 5 is near the two ends of bearing 7
It is designed with distance collar 8, the second transition axis 5 is additionally provided with the 3rd roller gear 52 that Tongzhou connects, and the 3rd roller gear 52
Diameter is less than the diameter of the second roller gear 51.
3rd roller gear 52 external toothing has the 4th roller gear 61, and the 4th roller gear 61 is set in hollow spline 6
On, and affixed with it.
All of bearing 7 is all self-aligning roller bearing 7；First roller gear the 41, second roller gear the 51, the 3rd Cylinder Gear
Wheel the 52, the 4th roller gear 61 is all helical gears.
