Abstract
The present invention relates to a kind of sliding bearing, including spindle body.It is characterized by: be at least evenly equipped with three axial dovetail grooves in the active section peripheral surface of spindle body, and active section two ends are provided with circumferential half dovetail groove；Axial dovetail groove and circumferential half dovetail groove fill up antifriction alloy；It is coated with antifriction alloy in the active section peripheral surface of spindle body, and combine together with the antifriction alloy in axial dovetail groove and circumferential half dovetail groove；Spindle body is provided with positioning shoulder block and dowel hole.Present configuration is simple, volume is little, handling ease, manufacturing expense is low, the circumferential and axial of the active section that spindle body contacts with planetary gear are machined with axial dovetail groove and circumferential half dovetail groove, antifriction alloy in dovetail groove combines together with the antifriction alloy of coating in peripheral surface, and antifriction alloy is well combined with spindle body, even if being not easy to peel off under stress, wear-resistant corrosion-resistant, radial and axial spacing accurately, good reliability, improve sliding bearing service life.
Description
Technical field
The present invention relates to a kind of bearing, be specifically related to the sliding bearing of a kind of planet circular system for high-speed overload.
Background technology
The supporting structure of the sliding bearing of existing widely used planet circular system is: the wheel rim of planetary gear is bearing shell, and the mandrel matching with bearing shell is axle journal, and both consist of bush bearing.For improving its wearability, the generally outer surface upper anti-friction material in steel mandrel: such as babbit, owing to the outer surface of steel mandrel is smooth surface, in rotation process, babbit easily peels off, reduce the service life of bearing, next to that this bearing arrangement is complicated, processing charges is high.
Content of the invention
The invention aims to overcome the shortcoming of above-mentioned technology, provide a kind of simple in construction, easy to manufacture, expense is low, the not flaky sliding bearing of antifriction alloy.
The sliding bearing of the present invention, including spindle body, it is characterised in that: being at least evenly equipped with three axial dovetail grooves in the active section peripheral surface of described spindle body, active section two ends are provided with circumferential half dovetail groove；Described axial dovetail groove and circumferential half dovetail groove fill up antifriction alloy；It is coated with antifriction alloy in the active section peripheral surface of described spindle body, and combine together with the antifriction alloy in axial dovetail groove and circumferential half dovetail groove.
In order to preferably be attained in that
In the active section peripheral surface of described spindle body, the thickness of the antifriction alloy of coating is 1～1.5 millimeter.
Described spindle body is provided with positioning shoulder block and dowel hole.
The sliding bearing of the present invention, simple in construction, volume are little, handling ease, reduce manufacturing expense；The circumferential and axial of the active section contacting with planetary gear at spindle body are machined with axial dovetail groove and circumferential half dovetail groove, antifriction alloy in dovetail groove combines together with the antifriction alloy of coating in active section peripheral surface, antifriction alloy is well combined with spindle body, even if being not easy to peel off under stress, wear-resistant corrosion-resistant, radial and axial spacing accurately, good reliability, improve sliding bearing service life.
