CONVEYOR ROLLER ASSEMBLY, ITS APPLICATION AND END ELEMENT FOR CONVEYOR ROLLER Russian patent published in 2020 - IPC C03B35/18 

FIELD: machine building.

SUBSTANCE: present invention relates to a conveyor roller assembly suitable for use in a medium subject to considerable temperature fluctuations and to a solid end element. One-piece metal end element for use in a conveyor roller assembly in a medium subject to considerable temperature fluctuations, having a longitudinal axis, comprises a first end configured to be connected to a rotary device, and a second end. Second end comprises a solid body having two ends, inner diameter D, configured to be pushed on the end of the ceramic coil, and length L>0.3 D or preferably>0.5 D, wherein said solid body comprises at least three consecutive sections along longitudinal axis of solid body, namely: two end sections of solid body, having substantially continuous surface, and one section for transfer of torque between said sections. Torque transmission section comprises a plurality of holes with length Lb<L in the direction of the longitudinal axis, forming a plurality of strips between the openings, passing inside and mechanically elastically deformed when the end element is on the ceramic coil and during temperature fluctuations so as to transmit torque to the coil.

EFFECT: technical result is solid end element provides efficient transfer of torque to ceramic coil due to its elasticity due to deformation of the end element when the end element is on the ceramic coil.
