摘要: 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.

摘要: 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.

摘要: 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.

摘要: A rack lubricator is bolted to a drive pinion housing. The lubricator supports a porous felt gear on a rotatable shaft. Lubricant is ported through the shaft to the inner surface of the gear, and the gear wicks the lubricant onto the rack teeth, thereby coating the surface of the rack with minimal lubricant as the felt gear rolls with the rack.
