Abstract

Изобретение относитс к машиностроению и, в частности, к зубчатым передачам. Цель изобретени - повышение надежности зубчатого колеса за счет обеспечени упругости перемещений диска колеса при его самоустановке в зацеплении. Диск 9 с венцом 10 установлены на зубчатой полумуфте 8, закрепленной посредством щек 4, 5 и 2, 3 и упругих элементов 6, 7 на ступице 1. Между торцами диска 9 и соответствующими торцами щек 4, 5 с нат гом установлены дополнительные упругие элементы 11 или 12. При работе колеса диск 9 с венцом 10 самоустанавливаетс на полумуфте 8, выравнива нагрузку по длине зубьев венца 10. Элементы 11 или 12 обеспечивают упругость перемещений диска 9 при самоустановке и выбор люфтов в соединени х деталей колеса. 1 з.п. ф-лы, 2 ил.This invention relates to mechanical engineering and, in particular, to gears. The purpose of the invention is to improve the reliability of the gear by ensuring the elasticity of the movements of the wheel disk during its self-alignment. A disk 9 with a crown 10 is mounted on a gear half coupling 8 fixed by means of cheeks 4, 5 and 2, 3 and elastic elements 6, 7 on the hub 1. Additional elastic elements 11 are mounted between the ends of the disk 9 and the corresponding ends of the cheeks 4, 5 with tension. or 12. When the wheel is in operation, the disc 9 with the crown 10 self-aligns on the coupling half 8, equalizing the load along the length of the teeth of the crown 10. Elements 11 or 12 ensure the elasticity of the movements of the disc 9 during self-installation and the selection of backlashes in the joints of the wheel parts. 1 hp f-ly, 2 ill.

Claims

Claim

1. An elastic gear wheel containing a hub, a pair of main cheeks fixed on it and a pair of additional cheeks installed between the latter, main elastic elements placed between the corresponding main and additional cheeks, connecting the half cheeks to each other and placed between the additional cheeks with the possibility of self-installation on the half-coupling disk with a gear rim, characterized in that, in order to increase reliability by ensuring the elasticity of displacements of the disk during self-installation, at least at bottom of the mutually facing end faces of the disc and the respective additional fixing cheeks formed recess, and it is provided with a wheel arranged with an interference fit between said ends in the locking recesses with additional elastic elements.

2. Wheel on π. 1, characterized in that the cheeks are made in the form of disks corrugated by concentric annular corrugations, and the main elastic elements are in the form of rings coaxial to them.
