Title: Collar-type seal for sealing revolving shaft
Inventor: KOZHAEV ALEKSANDR JUR EVICH
IPC: F16J15/32
Filed: 1995-09-08
Granted: 1998-03-20
Abstract: FIELD: sealing technology. SUBSTANCE: seal includes flexible stepped bush 2 embracing shaft 1 to be sealed; lesser cylinder of bush 2 is made in the form of Г3, while larger one, in the form of sleeve 4; seal includes also crimping ring 10 embracing Г3 3 and axial stop for Г3. When ring 10 is fitted on Г3, the latter is deformed and gets pressed to shaft 1. Crimping ring 10 is provided with two rows of grooves smoothly located over circumference on surface directed towards Г3. Parameters of profile of normal section of groove are so selected that local zones with radial clearance between Г3 and shaft 1, i.e. wells are maintained under grooves. Axial displacement of rows of grooves excludes overlapping of wells under grooves of adjacent rows in direction of friction of Г3 over shaft 1. Interference in conjunction with Г3, friction area of Г3 and its material are selected on basis of inequalities τ<0,5[τ] and Q<0,5[Q], where τ и [τ] are actual and limiting specific friction forces for fatigue wear of material of Г3; Q and [Q] are actual and maximum permissible rates of leakage of fluid to be sealed over revolving shaft 1. During operation of seal, fluid being sealed flows to wells under one of rows of grooves and cooling fluid flows to wells under adjacent row of grooves. From the wells, both fluids flow to friction area of Г3 and shaft 1 lubricating them and enhancing wear resistance of Г3. EFFECT: enhanced wear resistance. 2 cl, 9 dwg
