STRUCTURAL COMPONENT MOUNTED ON POWER PADDLE MACHINE FOR TRANSFORMING MEDIUM FLOW ENERGY INTO MECHANICAL ENERGY Russian patent published in 2007 - IPC F04D29/04 

FIELD: power engineering.

SUBSTANCE: device has bushing-like section 2 mountable on power machine shaft. External periphery of the bushing has recess 4 for receiving ring 5. Ring 5, partially circularly surrounded by recess walls 4 forming ring around end faces, forms axial space with recess walls 4 shaped as circular ring and is held by the rigid wall 1 with frictional contact enveloping ring 5 in operation mode. To reduce soft plastic material rings wear, recess is available in rigid wall 1, encircling ring 5 end faces without walls of bushing-shaped section being available. One of lateral recess 4 restriction members is formed by the pipe-like part 7 detachably connected to a rigid wall 1.

EFFECT: increased service life.
