摘要： This anti-backlash gear includes a gear wheel and gear teeth. Each gear tooth comprises first and second flanks, a top face and a bottom face, wherein for each gear tooth each flank extends from the top face to the bottom face, wherein the gear teeth comprise a polymeric material which comprises a repeat unit of form I wherein t1, and w1 independently represent 0 or 1 and v1 represents 0, 1 or 2. For each gear tooth, at least one of said flanks comprises two or more surfaces arranged to form a single protrusion extending along the at least one said flank such that a tooth thickness of each gear tooth varies between the top face and the bottom face of said gear tooth in a direction parallel to an axis of rotation of the gearwheel in operation. In use, the single protrusion is elastically deformable so as to absorb backlash.

摘要： An opposed-piston engine includes a backlash reducing gear with at least a first and second gear that move relative to each other because of a hydraulic pressure applied within the gear. A backlash control system that includes the backlash reducing gear can dynamically adjust backlash between at least two gears in the gear train of the engine during operation of the engine instead of setting backlash prior to operation of the engine. A method for adjusting backlash in a two-stroke-cycle, opposed-piston engine with a backlash reducing gear includes providing hydraulic fluid, such as oil, to the gear, and allowing the backlash reducing gear to adapt to changes in the engine that include temperature changes, torque reversals, changes in load and the like. The backlash reducing gear adapts to changes in the engine by controlled leaking and intake of oil.

摘要： A transmission can include a first gear, a shaft, a second gear, a third gear and a first biasing member. The first gear can be disposed about a first rotational axis. The shaft can be disposed about a second rotational axis. The second gear can be fixedly coupled to the shaft and can be configured to meshingly engage the first gear. The third gear can be non-rotatably coupled to the shaft. The third gear can be axially slidable along the shaft and can be configured to meshingly engage the first gear. The first biasing member can bias the third gear axially away from the second gear and into engagement with the first gear.
