The disclosure specifies a gear assembly for an electric-motor assisted steering system, comprising an electric motor, a worm shaft which can be driven by the electric motor and which meshes with a worm wheel. The worm shaft has a recess on an end face which faces the electric motor, in which recess there is arranged an elastic element which applies an axial force to the worm shaft in the direction away from the electric motor. In the axial direction, the elastic element is supported by one end on an adjustment element, which is formed in such a way that it permits expansion of the elastic element in the axial direction when the axial force on the worm shaft exceeds a defined threshold value, and limits expansion of the elastic element when the axial force on the worm shaft lies below the defined threshold value.

A transmission device for lifting a sickbed is fixed on a head mounting or a bed end of the sickbed and contains: a gear seat, a cover, a power input assembly, and a power output assembly. The gear seat includes a first conduit, a second conduit, a first opening, and a receiving orifice. The cover is covered on the first opening of the gear seat. The power input assembly includes an input shaft and a first bevel gear. The power output assembly includes an output shaft, a second bevel gear, and a support element. The support element is rotatably connected with the output shaft. The support element has multiple reinforcement ribs surrounding around an outer wall of the support element and configured to abut against an abutting fence of the second conduit, and the second bevel gear meshes with the first bevel gear.

Proposed is a strain wave generator for a harmonic reducer, the strain wave generator including: a cam formed with a plurality of segmented cams on a long-diameter side and the same number of segmented cams on a short-diameter side alternately abutted along a circumferential direction, wherein each of the segmented cams on a long-diameter side has an outer circumference surface of a certain cylindrical surface of a small radius, each of the segmented cams on a short-diameter side has an outer circumference surface of a certain cylindrical surface of a large radius, and the cylindrical surface of each of the segmented cams on a long-diameter side and the cylindrical surface of each of the segmented cams on a short-diameter side, abutted each other, have a common tangent line at a meeting point thereof.

Coaxial gear mechanism, with a toothing system which is oriented axially with regard to a rotational axis of the coaxial gear mechanism; a tooth carrier with axially oriented guides; teeth which are received in the guides for engagement with the toothing system, the teeth being oriented with their respective longitudinal axes axially in the guides and being mounted in the guides such that they can be displaced axially; a cam disc which can be rotated about the rotational axis for the axial drive of the teeth; and a housing, in which a setting element for mounting the cam disc is provided, at least one bearing with rolling bodies being arranged between the setting element and the cam disc.

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 resolver assembly for a ducted-rotor aircraft is configured to detect and measure rotation of a spindle of the aircraft. The resolver assembly includes first and second gear-driven resolvers. The first and second resolvers are coupled about a shared pivot axis and are independently pivotable about the pivot axis to maintain engagement of the first and second resolvers with the spindle of the aircraft. The resolver assembly is configured such that the first and second resolvers are biased toward the spindle. The input shafts of the first and second resolvers are spaced from the pivot axis through respective first and second distances that extend outward from the pivot axis along respective first and second radial directions. The first distance is equal to the second distance and the first radial direction is not coincident with the second radial direction.
