Take turns drive mechanism, this kind of structure reduces the requirement of bearing axial carrying capacity, and gear processing and assembling process it is simple, can
Achieve the purpose that reduce design rate.
The technical solution adopted in the utility model are as follows: a kind of monocline gear auxiliary driving structure with thrust cone, the biography
Dynamic structure includes small monocline gear, big monocline gear, baffle and thrust cone；It installs at the axis both ends of the small monocline gear
There are the first cylinder roller bearing and the second cylinder roller bearing, is sequentially installed with positioning sleeve, four on the outside of the second cylinder roller bearing
Spot contact bearing and small round nut locked spacer component, the first cylinder roller bearing outside are equipped with small round nut locked spacer group
Part；The small monocline gear and the engagement of big monocline gear, for fixed baffle after gear assembly and for bearing monocline
The thrust cone of tooth engagement axial force is respectively arranged on the axis of small monocline gear teeth portion two sides；The axis of the big monocline gear
Both ends are equipped with third cylinder roller bearing and the 4th cylinder roller bearing, third cylinder roller bearing and the 4th cylindrical roller axis
It holds outside and big round nut locked spacer component is installed.
Further, the thrust cone is set to axial force side suffered by big monocline gear, and is installed by angled pin
In on small monocline gear；It is reserved with axial gap between the big monocline gear and thrust cone, close to pushing away for gear side
Oil groove is provided on power tapered end face, the stress end face of thrust cone is the conical surface.
Further, the oil groove is located at gear engagement flank.
Further, the radial clearance between four spot contact bearing and positioning sleeve is 1-2mm.
Further, the baffle is installed on small monocline gear by bolt.
The utility model has the beneficial effects that bearing the axial force that monocline tooth engagement generates by thrust cone, shafting both ends are not
The bearing for bearing larger axial force need to be placed, only side placement positioning bearing.Transmission device is solved under the operating condition of high-speed overload
Bearing type selecting difficult problem reduces design rate, processing and assembly difficulty, reaches and is driven shape using the monocline tooth of simple structure
Formula just meets transmitting power, changes the demands such as revolving speed, and design is rationally, economic and practical, is easy to promote and use on a large scale.
