120 clampings corresponding with clamping groove 111.
In the present embodiment, the main function of the first buffer element 300 is to connect hob assembly 100 and buffer function, by
Need to drive hob assembly 100 to rotate in hobboing cutter axis 200, to realize the purpose mowed, hobboing cutter axis 200 is needed by the as a result,
One buffer element 300 drives hob assembly 100 to rotate, and so, when the first buffer element 300 is preferably torsion spring, needs
The clamping structure of clamping torsion spring end is set on the fixing piece 110 of hob assembly 100, correspondingly, on hobboing cutter axis 200
Same setting clamping structure, and torsion spring is then set on hobboing cutter axis 200, under normal condition, hobboing cutter axis 200 will by torsion spring
Torque passes to fixing piece 110, then drives entire hob assembly 100 to rotate by fixing piece 110, to realize mowing purpose；?
When hob assembly 100 collides hard objects, hob assembly 100 makes torsion spring reverse certain angle, to absorb collision energy, thus
Play certain buffer function.
When the first buffer element 300 is preferably flexible gaskets, through-hole is opened up on fixing piece 110, is set in hobboing cutter axis 200
On, and flexible gaskets are filled between through-hole and hobboing cutter axis 200 and pushed against, under normal condition, when hobboing cutter axis 200 rotates, pass through
Abutting, the rubbing action of flexible gaskets are able to drive the rotation of hob assembly 100, to realize mowing process；When hob assembly 100
When touching hard objects, relative motion or hobboing cutter axis 200 and flexible pad occur between hob assembly 100 and flexible gaskets
Relative motion occurs between circle or relative motion occurs between flexible gaskets for hob assembly 100, hobboing cutter axis 200, this
When, under the frictional force effect of flexible gaskets, certain buffer function can be played.
Further, the second buffer element 400 uses pressure spring, at this point it is possible to set in the one or both ends of hobboing cutter axis 200
Pressure spring is set, specifically, when pressure spring is arranged at one end, it, can be by hob assembly 100 and hobboing cutter axis under the action of pressure spring
200 squeeze to the other side, have been arranged retaining ring 600 on one end on hobboing cutter axis 200 far from pressure spring as a result, the retaining ring 600 card
On hobboing cutter axis 200, and retaining ring 600 is then connected on the side plate 510 of rack 500, so, in pressure spring and retaining ring 600
Under the action of, hob assembly 100 and hobboing cutter axis 200 can then keep stablizing between 500 both side plate 510 of rack, to prevent out
The problem of existing play.In addition, when hob assembly 100 is by active force in the axial direction of hobboing cutter axis 200, additionally it is possible to pass through pressure
Power spring plays buffering, damping effect, reduces the damage collided to transmission mechanism, driving mechanism.It is set when at 200 both ends of hobboing cutter axis
When setting pressure spring, then the both ends of the surface of hob assembly 100 are squeezed respectively by two groups of pressure springs, so as to guarantee hobboing cutter
Component 100 keeps original position without play phenomenon between 500 both side plate 510 of rack, likewise, colliding
When, two groups of pressure springs can also play certain buffering, damping effect.
Further, in order to realize the installation of hobboing cutter axis 200 and be rotated convenient for it, in hobboing cutter axis 200 in the present embodiment
It is provided with bearing 700 between both ends and the two side walls of rack 500, thus one, pressure spring is then extruded in hob assembly 100
Between fixing piece 110 and bearing 700.
