Abstract

This invention relates to mechanical engineering, in particular gearing. The purpose of the invention is to increase reliability by increasing the wear resistance of the teeth. The gear includes a body 1, a gear rim with teeth 2, face plates 3 attached to body 1 by bolts 4 with nuts 5 and having a gap with teeth ends 2. When the wheel operates as part of a gear transmission together with a conventional wheel without linings 3 on the first wheel prevents free extrusion of lubricant from the working surfaces of the teeth 2 onto their ends and ensures its accumulation in the gap with subsequent recirculation back to the working surfaces of the teeth 2 due to its adhesion properties. On the other hand, the presence of a gap between the plates 3 and the ends of the teeth 2 provides a predetermined elasticity of the teeth 2 under the influence of the loads acting in the gear. 2 Il.

FIG. 2

This invention relates to mechanical engineering, in particular gearing.

The purpose of the invention is to increase reliability by increasing the wear resistance of the teeth through the use of linings that hold the lubricant in the gap between them and the ends of the teeth.

FIG. 1 shows a wheel, cross section; in fig. 2 shows section A-A in FIG. one.

The gear contains a body 1, a ring gear with teeth 2, face plates 3 attached to the body 1 by bolts 4 with nuts 5. This wheel, when used in a gear, must be 10

working surfaces of the teeth 2 on their ends. The pads 3 form with the ends of the teeth 2 cavities (gaps) that serve as lubricant storage pockets, from where it recirculates back to the working surfaces of the teeth 2 due to its adhesion properties. The presence of a gap between the plates 3 and the ends of the teeth 2 provides a predetermined elasticity of the teeth 2 under the influence of loads acting in the transmission.

Claims (1)

Invention Formula A gear wheel comprising a hub, a ring gear and face lining in the form hooked to a conventional gear wheel, not discs mounted without a gap on the hub, having a pad that is distinguished by the fact that, in order to increase When the cogwheel is working in the hold-down by increasing the wear of the lining of the 3 preventive teeth with the other wheel, the discs are installed to allow the free extrusion of the lubricant with rum to the ends of the teeth. working surfaces of the teeth 2 on their ends. The pads 3 form with the ends of the teeth 2 cavities (gaps) that serve as lubricant storage pockets, from where it recirculates back to the working surfaces of the teeth 2 due to its adhesion properties. The presence of a gap between the plates 3 and the ends of the teeth 2 provides a predetermined elasticity of the teeth 2 under the influence of loads acting in the transmission.
