A silicone modified lubricant includes a Group I, II, III, IV or V base oil in combination with a minor amount of a silicone oil. Further, the lubricant includes a dispersant such as a dispersant olefin copolymer which maintains the silicone oil dispersed in the base oil. The silicone oil reduces the surface tension of the lubricant thereby reducing power loss. Preferably the lubricant formation has a surface tension less than 28 mN/m, making it particularly suitable for dip lubrication systems.

Silicone modified lubricant

A bearing interface of an apparatus, the apparatus having a first element and a second element configured to move relative to each other during operation of the apparatus, the first element comprising a first bearing surface configured to engage at least a portion of a second bearing surface of the second element thereby defining a contact zone between the first bearing surface and the second bearing surface, the first bearing surface having at least one recess indented into the first bearing surface, wherein the dimension of the recess in the direction of movement of the second element relative to the first element is less than the dimension of the contact zone in the direction of movement of the second element.

Bearing interface with recesses to reduce friction

A gear or engine oil or other type of lubricant, which effectively reduces churning losses in a dip lubrication system or any lubrication system where churning loss occur has a surface tension less than 28 mN/m and viscosity less than 400 mPa-sec at 25&#xb0; C. (about 500 cSt at 25&#xb0; C.). Formulations include Group I-IV base oil, in combination with an amount of silicone oil effective to decrease the surface tension of the oil, thereby reducing churning losses. When the base oil is prominently Group III, the coefficient of friction of the gear oil is also reduced.

Gear and engine oils with reduced surface tension

Energy loss in a dip lubrication system is reduced by reducing the immersion depth of the gear within a pool of oil. This can be accomplished by increasing the pressure within the dip lubrication system which effectively reduces the flow rate of the oil so that the oil remains separated from the oil pool for a longer period of time thereby reducing the oil level and the immersion depth of the gear within the oil pool. Alternately, this can be accomplished by substituting a higher density gas for air which has the same effect. In a third embodiment the immersed gear includes wind vanes that direct air against the oil pool creating a trough which effectively reduces the immersion depth of the gear within the oil pool.

Lubrication system and method for reducing dip lubrication power loss

A rotary pump for pumping compressible fluid comprising an eccentrically mounted rotor and a stator . The stator comprises a stator inner liner that is free to rotate, driven directly or in response to rotation of the rotor such that the relative velocity between the outer surface of the rotor and the inner surface of the stator is reduced. The vanes are held at each end by sockets in the rotor and stator . The vane and socket coupling provides fluid sealing without liquid lubricant. Opposing solid lubricant and hard surfaces are used on contact surfaces between the elements.
