Description

I 1

The invention relates to mechanical engineering, in particular, to gears of gears with higher kinematic precision.

The aim of the invention is to increase the reliability and durability of a gear in bevel and worm gears, by ensuring the elastic flexibility of the set teeth in the axial direction while maintaining the kinematic accuracy of the gear.

Fig. 2 shows section A - A in Fig. 1 in Fig. 3 - a gear wheel with inserted teeth of a bevel gear; Fig. A - section BB on fig.Z

The serrated or conical gear wheel contains a hub 1 with washers 2 fixed at its ends, in which radial rectangular windows are fitted with end parts of the inserted teeth 3.

Between the insert teeth 3 and the hub 1 there is an annular V-shaped spring 4.. Between the washers 2 and the hub 1 there are mounted disks 5 5, with straining lobes extending into the rectangular windows of the washers 2. At each end the wheels are a pair of additional disks 6 and 7, one of which (disk 6), placed between the wheel and disk 7, is made elastic in the circumferential direction beyond

surface of the inserted tooth 3. Elastic deformation of the disk 6 within the gap M is selected within half the tolerance for the axial length of the teeth.

When the wheel is in gear, teeth 3 are permanently fixed in the axial direction by additional disks 6 and 7, and the gearing errors are compensated for by the elasticity of the corrugation on the additional disk 6.
