DEVELOPMENT OF REPAIR KITS FOR KNOTS OF TRANSPORT EQUIPMENT AND TECHNOLOGICAL EQUIPMENT

Аннотация

Sliding and rolling bearings are applied in transportation and production equipment, these bearings
operate under high loads in reciprocating/rotary mode. They are used in railroad, road, and agricultural transport for
suspensions, dampers, steering, shaft drives, in garment equipment, mining, oil and gas production and processing, as
well as some other industries. However, their operation lifetime is insufficient and recovery of such couplings by
conventional methods comprised of replacement with repair kits of similar design does not solve this problem.
As assumed in this article, the operation lifetime of couplings operating under heavy loading in
reciprocating/rotary mode can be increased by improved recovery of their operability using repair kits based on new
operation principles of tribocouplings, that is, sliding bearings with movable spring bearing boxes.
The design of repair kit design of rubber bushing in the form of sliding bearing with movable conical spring
boxes has been theoretically substantiated. Mathematical models of size variations of movable conical spring box of
sliding bearing of damper rubber bushing have been developed.
Theoretical importance of the work is comprised of the expanded proven concepts of recovery of damper rubber
bushings using repair kits with movable spring boxes. Practical significance is that the developed repair kits of
damper rubber bushing are characterized by operation lifetime higher by 1.5…2 times in comparison with regular
kits.
The obtained results can be applied for development of new engineering solutions, for improvement of recovery
of transportation and production equipment with couplings operating under high loads in reciprocating/rotary mode.
