A hydrodynamically lubricating geometry for the generally circular dynamic sealing lip of rotary seals that are employed to partition a lubricant from an environment. The dynamic sealing lip is provided for establishing compressed sealing engagement with a relatively rotatable surface, and for wedging a film of lubricating fluid into the interface between the dynamic sealing lip and the relatively rotatable surface in response to relative rotation that may occur in the clockwise or the counter-clockwise direction. A wave form incorporating an elongated dimple provides the gradual convergence, efficient impingement angle, and gradual interfacial contact pressure rise that are conducive to efficient hydrodynamic wedging. Skewed elevated contact pressure zones produced by compression edge effects provide for controlled lubricant movement within the dynamic sealing interface between the seal and the relatively rotatable surface, producing enhanced lubrication and low running torque.

Bypass clutches capable of transmitting the power to the respective transmission gear trains are provided at an end portion of the input shaft, and the engine power is transmitted to the output shaft via at least any one of the bypass clutches at a time of shifting gears. The input clutch and the plurality of bypass clutches are concentrically arranged in series between the engine and the input shaft providing size reduction.

By using the same liquid for cooling and lubricating a feed shaft, a simpler structure is obtained, thereby allowing easier maintenance. A feed shaft that is rotatably supported at one end thereof moves a slide of a machine tool. The feed shaft is supported by a support member via a bearing. A pipe is fitted to the feed shaft, and a pathway space is provided allowing the reciprocal flow of the cooling/lubricating liquid in the axial direction. Some of the cooling/lubricating liquid supplied via the support member to the feed space passes through the pathway space as cooling liquid, cools the feed shaft, and is held in a discharge space. At the same time, some of the cooling/lubricating liquid flows, as lubricating liquid, into the bearing, is discharged, and is held in a discharge space. The cooling/lubricating liquid in the discharge space that has absorbed the heat of the structure is immediately discharged out of the support member.

A multi-part piston for an internal combustion engine has an upper piston part having a piston crown, and a lower piston part. The lower piston part has pin boss supports and pin bosses connected with them and the upper piston part and the lower piston part each have an inner and an outer support element, which elements delimit an outer circumferential cooling channel. The inner support elements delimit a cavity that is open toward the pin bosses. The cavity has a separate cooling oil collector that has at least one cooling oil opening. The piston is produced by manufacturing the upper piston part and lower piston part, inserting the cooling oil collector into the upper piston part or lower piston part, and joining the upper and lower piston parts together by friction welding.

A radially pressure balanced floating seal system is used to seal a rotating shaft, such as a drive shaft in a torpedo, or other type of vehicle or machinery. The radially pressure balanced floating seal includes an outer seal housing and an inner seal housing that floats with respect to the outer seal housing. The outer seal housing is secured proximate the shaft bearings, for example, in the tail cone of a torpedo. The inner seal housing is secured within an internal recessed region in the outer seal housing, and two or more discrete torque members or one distributed torque member extend from the outer seal housing to the inner seal housing to prevent rotation of the inner seal housing while allowing movement generally in a radial direction. The inner seal housing includes a lubricant recess formed within an internal annular aperture of the inner seal housing for containing lubricant. Double canted O-rings are disposed on each side of the lubricant recess in double canted O-ring grooves. The double canted grooves and O-rings prevent unbalanced radial forces that might cause rubbing of the shaft against the seal housing. In one embodiment, the lubricant recess is double canted to also minimize the sealing length.

The eccentric shaft portion is installed with a plug member to close an upper end of the upper oil hole. The plug member is configured to selectively couple a weight balance member, which is separately fabricated from the rotating shaft, to an upper end of the eccentric shaft portion.
