An assembly for adjustably mounting a gear of a pump to a gear of a driver equipment includes a shroud member, and a hollow elongated stub-shaft. The stub-shaft includes a flange, and a hub member axially extending from the flange. The shroud member defines a first aperture whose diameter is greater than a diameter of the hub member. The hub member is received within the shroud member via the first aperture. The flange has a first set of holes to receive a first set of fasteners and releasably couple with the body of the pump. The flange also has a second set of holes that are configured to receive a second set of fasteners and releasably couple with the shroud member. A diameter of the second set of holes is greater than a diameter of the second set of fasteners.

A fluid pump includes a pump element in communication with an inlet and an outlet. Rotation of the pump element generates a suction at the inlet and pressure at the outlet. The suction and pressure cooperate to move a fluid through a fluid path. An accessory fluid path is in communication with the inlet and outlet. The accessory fluid path includes a thermistor in communication with the accessory fluid path. The thermistor monitors a temperature of the fluid within the accessory fluid path.

A product may include a case, and a shaft that rotates may extend into the case. A bearing may support the shaft at the case. A seal may be positioned around the shaft outboard from the bearing. The bearing may have a first side facing the seal and a second side facing away from the seal. The case may define an inlet to an area between the bearing and the seal. A baffle may extend over the inlet on the second side and radially outside the bearing.

A steering mechanism having a piezoelectric element to adjust component clearance and preload based on steering inputs, road inputs, and time in service. The piezoelectric element positioned in the steering mechanism for electric adjustment so that the clearance and preload can be adjusted electrically in response to steering inputs, road inputs, and time in service. This arrangement allows for low preload and low friction when the vehicle is being driven over smooth road conditions. When a rough road condition is detected both clearance and preload can be electrically increased to minimize noise. The disclosed inventive concept may find application in a variety of steering mechanisms to minimize or eliminate NVH when the vehicle is driven over rough surfaces. Without limitation, the piezoelectric element may be provided in rack and pinion electric power assisted steering systems or in worm and wheel (steering column) electric power assisted steering systems.

A wind turbine rotor includes a hub, a plurality of blades, and a pitch system for rotating a blade substantially along its longitudinal axis. The pitch system includes a bearing, a motor, and a gear system, wherein the gear system has a driving pinion operationally connected with the motor, an annular gear arranged to mesh with the driving pinion. Additional gear teeth are arranged to mesh with other parts of the gear system in a predefined blade position for wind speeds at or below a nominal wind speed such that upon movement from the predefined blade position, the additional gear teeth come into contact with the other parts of the gear system before the driving pinion comes into contact with the annular gear.

A steering system comprises a first engagement member; a second engagement member to be engaged with the first engagement member; a supporting portion to support the second engagement member; and an elastic member at least partially enclosed in the supporting portion to apply a preload to the second engagement member and absorb an impact load. The elastic member has a first deformation under a first load and at least a second deformation under a second load greater than the first load, and a ratio of the first load to the first deformation is less than a ratio of the second load to the second deformation.

Backlash is controlled in an opposed-piston engine that includes two crankshafts disposed in a parallel, spaced-apart relationship and a gear train coupling the first and second crankshafts, the gear train including a driving gear coupled to the first crankshaft and a split gear assembly engaged with the driving gear to transfer rotation from the driving gear to the split gear assembly. The split gear assembly includes first and second gears, a spring mechanism that acts to angularly offset the first gear relative to the second gear in a first direction, and a one-way clutch mechanism that prevents relative angular movement of the first gear relative to the second gear in a second direction opposite the first direction.
