Abstract

Изобретение относитс к машиностроению, к сборным зубчатым колесам. Цель - повышение нагрузочной способности и упрощение сборки колеса. Это достигаетс за счет повышени жесткости арочной конструкции съемного венца и исключени крепежных элементов дл него. Венец арочной конструкции выполнен в виде охватывающей ступицу бесконечной спирали с пр молинейными участками 3, 4 витков на периферии, такими же пр молинейными участками 5, 6 витков на торцах и такими же пр молинейными участками 8 витков, обращенными к ступице. На последней выполнены зигзагообразно в ее окружном направлении пр молинейные канавки дл размещени участков 8. Участки 5, 6 наклонены друг к другу, а участки 3, 4 параллельны и вместе образуют рабочие поверхности зуба венца. При работе взаимный наклон участков 5, 6 обеспечивает жесткость арочной конструкции венца при сохранении упругой податливости зубьев участков 3, 4. Зигзагообразное взаимное расположение участков 8 позвол ет фиксировать венец на ступице в осевом направлении без использовани крепежных элементов. 3 ил.The invention relates to mechanical engineering, to modular gear wheels. The goal is to increase the load capacity and simplify the wheel assembly. This is achieved by increasing the rigidity of the arched design of the removable rim and eliminating fasteners for it. The crown of the arched structure is made in the form of an endless spiral enveloping the hub with straight lines 3, 4 turns on the periphery, the same straight lines 5, 6 turns on the ends and the same straight lines 8 turns facing the hub. On the latter, the rectilinear grooves are made in its circumferential direction in zigzag manner to accommodate the sections 8. The sections 5, 6 are inclined towards each other, and the sections 3, 4 are parallel and together form the working surfaces of the crown tooth. In operation, the mutual inclination of the sections 5, 6 provides rigidity of the arched crown structure while maintaining the elastic compliance of the teeth of sections 3, 4. The zigzag mutual arrangement of the sections 8 allows the crown on the hub to be fixed in the axial direction without using fasteners. 3 il.

Claims

Claim

A gear wheel containing a hub and a crown mounted on it in the form of an endless spiral wheel covering it in the circumferential direction with straight sections of turns on the periphery and the ends of the crown, characterized in that, in order to increase the load capacity and simplify assembly, the zigzag arranged on the hub periphery in its circumferential direction, rectilinear grooves, sections of the spiral turns facing the hub, are also made rectilinear and placed in the corresponding grooves of the hub, rectilinear sections adjacent turns at the ends of the crown are inclined to each other, forming a triangle with a vertex at the periphery of the crown, and the rectilinear sections of neighboring turns at the periphery of the crown are parallel to each other and they are connected with the mentioned vertices of triangles placed on opposite ends of the crown.
