Abstract

The invention relates to mechanical engineering. The purpose of the invention is to increase reliability by reducing the axial load on the driven shaft. Slave disk 1 and thrust disk 2 are rigidly mounted on shaft 3 and are made in the form of plates that are elastic in the axial direction. The drive disk 4 is placed between the disks 1 and 2, interacts with the first one and is mounted on the shaft 5, the axis of which intersects the axis of the shaft 3. The inner ring of the radial rolling bearing 6 is rigidly fixed on the shaft 5, and the outer ring interacts with the stop disc 2. Axial force The shaft acting on the shaft 3 is partially or fully balanced by the axial force acting on the shaft 3 at the contact of the bearing 6 and the thrust disk 2, thereby eliminating the axial force on the shaft 3. 1 Il.

FIELD OF THE INVENTION The invention relates to mechanical engineering, namely to frictional gears of rotational motion.

The aim of the invention is to increase reliability by reducing the axial load j on the driven disk shaft.

The drawing shows a friction transmission, general view.

The friction gear contains a weighed 1 and an anvil disc 2 rigidly mounted on the shaft 3, DisC) And 1 and 2 are made in the form of plates elastic in the axial direction. The master disk 4 is located between the resistant 2 and the slave 1 disks - and interacts with the latter. The drive plate 4 is mounted on the shaft 5, the axis of which intersects with the axis of the shaft 3. On the shaft 5 coaxially the drive disk 4 has a radial rolling bearing 6, the inner ring of which is rigidly fixed on the shaft 5, and the outer ring interacts with the stop disk 2,

The friction transmission operates as follows.

Rotation from drive unit 7 is transmitted through master disc 4.
