Neck and the second neck connect to form kidney ellipsoid neck.End face end face end face end face
The cooperation of stopper slot and limited block is used to align the tooth in first gear and second gear with tooth, is additionally operable to make the
One gear and second gear mutually support, and preventing gear wheel, stress is excessive causes first gear and second when being initially engaged in engagement
Gear relatively rotates, and causes the tooth in first gear and second gear to stagger with tooth, causes the accident, through hole and screw thread
Hole is used to be fixedly connected with first gear with second gear by bolt, the first neck and the second neck for on gear shaft
Card key coordinates, and realizes gear and gear shaft synchronous axial system.
Further, in order to increase the lifting surface area of stopper slot and limited block, the stopper slot and limited block are arc knot
Structure.
Further, when being initially engaged in engagement, stress is excessive in order to prevent gear wheel causes first gear and second gear to be sent out
It is raw to relatively rotate, cause the tooth in first gear and second gear to stagger with tooth, the first gear is close to the second gear
End face on be uniformly provided with four stopper slots, the second gear is provided with the limit coordinated with the stopper slot in first gear
Position block.
Further, when being initially engaged in engagement, stress is excessive in order to prevent gear wheel causes first gear and second gear to be sent out
It is raw to relatively rotate, cause the tooth in first gear and second gear to stagger with tooth, the first gear is close to the second gear
End face on be uniformly provided with two stopper slots and two limited blocks, the stopper slot is arranged at intervals with the limited block, described the
Two gears are provided with two limited blocks coordinated with described two stopper slots in first gear and two limited blocks and two limits
Position groove.
Further, when being initially engaged in engagement, stress is excessive in order to prevent gear wheel causes first gear and second gear to be sent out
It is raw to relatively rotate, cause the tooth in first gear and second gear to stagger with tooth, the first gear is close to the second gear
End face on be uniformly provided with four limited blocks, the second gear is provided with the limit coordinated with the limited block in first gear
Position groove.
Further, in order to reduce noise during gear engagement, first gear and the second gear flank of tooth is laterally
The arcwall face of protrusion.
The beneficial effects of the utility model are：A kind of split type helical teeth gearshift roller gear provided by the utility model, is adopted
With first gear and second gear split settings, when first gear or second gear are worn, part replacing is carried out, is saved
Production cost.
