US Patent:

40467031, Sep 6, 1977

Filed:

Nov 26, 1975

Appl. No.:

5/635561

Inventors:

Irl N. Duling - West Chester PA
David S. Gates - Swarthmore PA

Assignee:

Sun Oil Company of Pennsylvania - Philadelphia PA

International Classification:

C10M 116
C10M 310

US Classification:

252 59

Abstract:

Perhydrogenated dimers of styrene or a methylated styrene have very high coefficients of traction and are therefore useful as traction fluids. A preferred dimer is 1-cyclohexyl-1,3,3-trimethylhydrindane.

Abstract:

A composition useful as a base stock for a lubricant in a traction drive transmission has a kinematic viscosity at 210. degree. F in the range of 1. 5-200. 0 cs. and contains A. from 1-25 parts by weight of a hydrogenated polymer of C. sub. 3 -C. sub. 8 aliphatic monoolefin, said polymer having an average molecular weight in the range of 180-2000, and B. one part by weight of at least one member selected from I. at least one saturated adamantane compound, said adamantane compound containing no elements other than carbon, hydrogen, fluorine and oxygen, wherein said oxygen is combined in an ether or an ester linkage or is in a carboxylic acid, hydroxyl or carbonyl group; Ii. a paraffinic petroleum oil containing less than 1% by weight of aromatics and having an ultraviolet absorptivity at 260 millimicrons of less than 0. 5; and Iii.

International Classification:

C10M 120

US Classification:

252 52R

Abstract:

A friction or tractive drive comprises at least two relatively rotatable members in torque transmitting relationship, the tractive surfaces of the members having disposed thereon a tractant selected from the following groups (A) or (B): A. a tractant comprising a hydrocarbon dimer of an alkyladamantane and/or alkyladamantanol of the C. sub. 12 -C. sub. 19 range containing 1-3 alkyl groups of the C. sub. 1 -C. sub. 3 range, the dimer containing two adamantane nuclei which are linked to each other through an alkylene radical derived from and having the same number of carbon atoms as an alkyl group of the starting material; and B. an ether analogous to a hydrocarbon dimer from group (A) but in which there are two linkages between nuclei, one being an oxymethylene or oxyethylene radical, the other being a methylene or ethylene radical.
