Abstract: A transmission mechanism includes a housing, a first rotating member accommodated in the housing and rotatable about a first rotating member axis, and a lubricating member accommodated in the housing and containing a lubricant. While the first rotating member rotates about the lubricating member, the lubricating member applies a preload to and comes into contact with a part of the first rotating member on the basis of an elastic force, so that the part of the first rotating member is lubricated with the lubricant.

Abstract: The present invention relates to a linear electro-mechanical actuator for transferring a rotational motion to a linear motion. The actuator provides a piston being at least partly arranged inside a housing. The actuator further provides a transmission module including a rotating portion having a load-carrying surface and a non-rotating portion being operatively engageable to each other. The transmission module is adapted to transfer a rotational motion of the rotating portion to a linear motion of the piston via the non-rotating portion. The actuator further provides a lubricating member having a porous polymeric matrix and a lubricating material, the load-carrying member being arranged adjacent to the transmission module. Thereby, the actuator allows for lubrication of at least a portion of the load-carrying surface of the rotating portion upon movement of the rotating portion. The linear electro-mechanical actuator may not require, or may at least minimize, the need of relubrication.

Abstract: There is provided an oil separating structure of an automatic transmission, which makes it difficult for an oil strainer of an oil pump to draw oil containing air bubbles. A baffle plate base separates a space around the oil strainer and a space around a driven sprocket as well as a final gear, and therefore, oil containing air bubbles formed as a result of agitation by the driven sprocket, chain, and final gear does not flow directly into the oil strainer. As a result, the oil strainer is unlikely to draw oil containing air bubbles.

Abstract: A split tube containing a lubricant is engaging a bicycle chain. The lubricator tube is carried by the chain during the initial chain operation until the tube end contacts a barrier surface on the chain drive mechanism. The barrier may be the pivoting idler arm, the derailer mechanism, or a portion of the bicycle frame. The device brings the lubricant in intimate contact with the chain allowing the use of semi-solid, liquid, and solid-solvent mixture of lubricants.
