Powdered metal variator components
View Patent ↗The use of powder metal components in a variator is disclosed. Traction fluid of various sorts may be used in the variators, not just high performance synthetics or application specific lubricants.
1. A variator comprising:
a housing;
a powder metal disc enclosed within the housing having a contact surface, a density less than 7.7 g/cc, a roughness greater than 0.2 micrometers and a hardness less than 62 HRc; and
a powder metal roller in sliding contact with the disc contact surface having a density less than 7.7 g/cc, a roughness greater than 0.2 micrometers and a hardness less than 62 HRc; wherein the powder metal disc and the powder metal roller each comprises a steel alloy.
2. A variator of claim 1 further comprising a mineral based traction fluid on the disc contact surface.
