SPHERICAL JOINTS POLYMER INSERTS RESTORATION METHOD Russian patent published in 2018 - IPC B23P6/00 F16C11/06 

FIELD: motor vehicle industry.

SUBSTANCE: invention relates to the automotive engineering industry, namely, to undismountable spherical joints restoration methods, mainly in the vehicle suspension elements (levers, steering rods, tips). During the spherical joints polymeric inserts restoration, opening the spherical joint, cleaning the connection, restoring or changing the spherical joint pin. Then, to the spherical joint body attaching the bottom washer having the central threaded hole for the centering nozzle, which is a cylinder with external thread, from one end of which a conical depression is made, in which the pin is placed with the ball into the nozzle, and the radial grooves for the polymer passage, wherein inside the cylinder a polymer pouring channel is made. Using the nozzle, setting the pin required position in the spherical joint body, performing the polymer filling, placing the lubricant, and closing the bottom washer remaining hole with plug. It is possible to connect the bottom washer with threaded hole to the spherical joint body by welding. During the pouring process, it is possible to additionally cool down the polymer exit zone. Bottom washer hole plug can be made removable.

EFFECT: restoration process simplification and reducing its duration, increase in the spherical joint repair quality, increase in its service life and increase in the restored connection maintainability during further operation.
