Description

(54) RIDING

FIELD OF THE INVENTION The invention relates to general engineering, namely to high-speed sliding onors.

The known hydrostatic sliding bearing includes a movable shaft with axial and radial channels for supplying lubricant to the friction zone and covering its floating liner, on the working surface of which there are channels for diverting lubricant arranged coaxially to the channels of shaft 1.

In the known support, when using gas as a lubricant, a phenomenon of loss of stability of the shaft is observed at significant rotational speeds due to the appearance of a “half-speed vortex, which causes the shaft to oscillate and causes the shaft to come in contact with the liner, i.e., loss of support.

The aim of the invention is to increase the vibration resistance of the support by forming the circle of the rolling element of the wave-shaped lubricant layer.

This goal is ensured by the fact that the number of channels for the supply of lubricant is chosen according to the invention not to be multiple to the number of channels for its removal.

In doing so, the channels for diverting lubrication can be made deaf or in communication with the atmosphere.

FIG. 1 shows a longitudinal section of a slide bearing of the proposed design with blind channels for draining lubricant and feeding it through a shaft; in fig. 2 and 3 are a slide bearing with channels for discharging lubricant in communication with the atmosphere and feeding it through an insert; in fig. 4 - Slip bearing with lubrication channels communicating with the atmosphere and supplying lubricant through the shaft.

The slide bearing contains a movable element (shaft) 1 with an axial channel 2 and radial channels 3 for supplying gas lubricant or its removal from the working surface 4 of shaft 1. In axial channel 2 of shaft 1, a blade 5 can be placed, working to inject or suck gas lubricant } and, at the same time, there is no need to supply lubricant under pressure.

The shaft 1 is placed in the hole of the fixed liner 6, on the working surface 7 of which the deaf or communicating channels 8 are made to divert or supply gas lubricant to the friction zone.
