Side is equipped with big round nut locked spacer component.
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.
Beneficial effects of the present invention: the axial force that monocline tooth engagement generates is born by thrust cone, shafting both ends are not required to put
The bearing for bearing larger axial force is set, only side placement positioning bearing.Transmission device is solved in the operating condition lower bearing of high-speed overload
Type selecting difficult problem reduces design rate, processing and assembly difficulty, reaches the monocline tooth driving form using simple structure,
With regard to meeting transmitting power, changing the demands such as revolving speed, design is rationally, economic and practical, is easy to promote and use on a large scale.
