HYDRODYNAMICAL RETARDER Russian patent published in 2008 - IPC F16D57/04 B60T10/02

Abstract RU 2340804 C2

FIELD: transport.

SUBSTANCE: invention relates to motor industry, namely to hydrodynamic retarders. Retarder contains rotor blade wheel with number Z_R blades, stator blade wheel with number Z_S blades. Rotor blade wheel and stator blade wheel form toroidal work chamber between them in which via working medium torque is transmitted from rotor blade wheel (2) to stator blade wheel. Blades have profile with inner diameter D₁ and outer diameter D_A. Mean number Z_m of blades, derived from half of the sum of number Z_R of rotor blades and number Z_s of stator blade multiplied by coefficient f_v profile shift coefficient derived by division of outer profile diameter D_A,V radial shifted with regard to normal profile by normal profile outer diameter D_A, is established depending on work medium. Z_m for work medium oil comprises 22-25, in particular 23.5^±0.35, and for work medium water or water mixture - 19-22, in particular 20.5^±0.35. Normal profile is determined by the following relation: D_I=0.4^±0,05D_A. Decrease of noise is reached and degree of constructive freedom is preserved.

EFFECT: decrease of noise is reached and degree of constructive freedom is preserved.
