Definitions
- the present invention involves the use of dimethylsilicone fluids of moderate viscosity and/or di-alkyl or di-cycloalkyl or alkyl-cycloalkyl, or mixtures thereof, of di-end-capped polypropylene oxides or of ester compounds in combination with cyclic hydrocarbons to produce very high shear strength elastohydrodynamic (EHD) traction fluids and to modify the low temperature viscometric properties of the mixed fluids without adversely affecting the very high elastohydrodynamic shear strength or traction coefficients of the very high shear strength cyclic hydrocarbon fluid in the resulting mixed fluids with improved low temperature viscosity.
- EHD elastohydrodynamic
- Elastohydrodynamic traction drives are power transmission devices that operate by transmitting torque through a thin elastohydrodynamic film of fluid between nominally-smooth, rolling-sliding, highly-loaded contacts.
- the efficient transfer of torque relies upon the high- stress shear strength of the fluid used to lubricate the surfaces in these high-stress elastically- deformed contacts.
- Fluids with very high elastohydrodynamic shear strength, or high traction coefficients enable the most efficient transfer of torque through these contacts from one surface to the other.
- the shear strength properties of the fluid under the EHD contact operational conditions effectively dictate the sizing of the device for a given power or torque transfer requirement.
