The purpose of this utility model can be realized by the following technical scheme: a kind of helical gear coaxial transmision, including
Cabinet, input shaft, output shaft and several gear assemblies, the input shaft and output shaft be arranged in respectively the both ends of the surface of cabinet and
For coaxial arrangement, which is characterized in that the end of the input shaft is fixed with helical gear one, and the end of the output shaft is fixed with tiltedly
Gear two, the gear assembly includes master gear, pinion, tooth shaft one and tooth shaft two, and tooth shaft one and helical gear one are mutual
Engagement, tooth shaft two and helical gear two are intermeshed, and the master gear is respectively fixedly connected in the both ends of tooth shaft one, the secondary tooth
Wheel is respectively fixedly connected in the both ends of tooth shaft two, and the tooth shaft one and tooth shaft two are upper and lower parallel construction and are separated from each other, described
Master gear and pinion intermeshing, several axis holes installed for tooth shaft one and tooth shaft two are offered on the cabinet.
The principle of this helical gear coaxial transmision is the tooth ratio by changing master gear and pinion, tooth shaft two and helical teeth
The tooth of wheel two is driven the entirety for making transmission device by helical teeth than achieving the purpose that adjust input shaft and output shaft speed ratio
Volume is smaller to be easily installed.
In a kind of above-mentioned helical gear coaxial transmision, the end of the input shaft and output shaft is spline knot
Structure.
In a kind of above-mentioned helical gear coaxial transmision, between the input shaft and helical gear one, output shaft and
It is an integral structure between helical gear two.
In a kind of above-mentioned helical gear coaxial transmision, the quantity of the gear assembly is 3 groups.
Compared with prior art, this helical gear coaxial transmision has the advantage that through master gear and pinion, tooth
The cooperation adjusting speed ratio of axis two and helical gear two, keeps the transmission accuracy of this transmission device higher, and tooth shaft one and tooth shaft two-phase
The mutually parallel and small overall structure for making the present apparatus in interval is more compact, and most preferably 3 groups of gear assembly are spaced angle phase between each other
Together, the torsion upper limit of present apparatus receiving can effectively be increased.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 and Figure 2, this helical gear coaxial transmision, including cabinet 1, input shaft 2, output shaft 3 and several teeth
Wheel assembly 4, input shaft 2 and output shaft 3 are arranged in the both ends of the surface of cabinet 1 and respectively to be coaxially disposed, and the end of input shaft 2 is connected
Have a helical gear 1, the end of the output shaft 3 is fixed with helical gear 26, gear assembly 4 include master gear 4a, pinion 4b,
Two 4d of one 4c of tooth shaft and tooth shaft, and one 4c of tooth shaft and helical gear 1 are intermeshed, two 4d of tooth shaft and helical gear 26 are intermeshed,
Master gear 4a is respectively fixedly connected in the both ends of one 4c of tooth shaft, and pinion 4b is respectively fixedly connected in the both ends of two 4d of tooth shaft, tooth shaft one
4c and two 4d of tooth shaft is upper and lower parallel construction and is separated from each other that master gear 4a and pinion 4b are intermeshed, and is offered on cabinet 1
