Abstract

Изобретение относитс к машиностроению. Цель изобретени - повышение равномерности передаточного отношени и КПД бесступенчатой передачи. Бесступенчата передача содержит два вала 1 и 4, которые при необходимости могут смещатьс в радиальном направлении параллельно друг другу. Два зубчатых конических диска 2 и 3 расположены на валу 1. Диск 5 имеет радиальные упругие в направлении, параллельном оси диска 5, пластины 6, на концах которых размещены пальцы 7. Диск 5 установлен на валу 4. При работе бесступенчатой передачи крут щий момент может передаватьс как с вала 1 через диск 5 на вал 4, так и с вала 4 через диск 5 на вал 1. Изменение передаточного отношени осуществл етс за счет радиального смещени вала 1 или вала 4 относительно друг друга. Равномерность передаточного отношени достигаетс за счет того, что пальцы 8, име возможность смещени в осевом направлении, обеспечивают беззазорное зацепление. 3 ил.The invention relates to mechanical engineering. The purpose of the invention is to improve the uniformity of gear ratio and efficiency of continuously variable transmission. The stepless transmission contains two shafts 1 and 4, which, if necessary, can be displaced in the radial direction parallel to each other. Two toothed conical disks 2 and 3 are located on the shaft 1. The disk 5 has radial elastic in a direction parallel to the axis of the disk 5, plates 6, at the ends of which fingers 7 are placed. The disk 5 is mounted on the shaft 4. When the transmission is continuously variable, the torque can transferred both from shaft 1 through disk 5 to shaft 4 and from shaft 4 through disk 5 to shaft 1. The gear ratio is changed due to radial displacement of shaft 1 or shaft 4 relative to each other. The uniformity of the gear ratio is due to the fact that the fingers 8, having the possibility of displacement in the axial direction, provide the backlash-free engagement. 3 il.

Claims

Claim

An infinitely variable transmission comprising a shaft, conical disks located on it with radial protrusions and depressions made on their conical surfaces, one of the disks is axially movable and located on the shaft so that its protrusions are opposed to depressions on another disc, and placed between the conical disks on a parallel shaft an intermediate link, on the circumference of which fingers are evenly spaced with axes parallel to the axes of the shafts, characterized in that, in order to increase the uniformity of the gear ratio and Efficiency, the intermediate link is made in the form of a disk with radial elastic plates in the direction parallel to the axis of the disk, with fingers extended at their ends.
