FEATHER JOINT Russian patent published in 2013 - IPC F16B3/00

Abstract RU 2502895 C1

FIELD: machine building.

SUBSTANCE: feather joint key length cross-section through an arc of outer frame joint surface should satisfy the relationship $l > 4 R_{\max} \arcsin \sqrt{\frac{δ_{\max}}{2 R_{\max}}},$ where l is key length, R_max is maximum radius of outer frame joint surface, δ_max is maximum radial clearance between joint surfaces of the frames. Proposed feather joint rules out key turn in circular chamber.

EFFECT: reliable joint.
