摘要： A drain proof seat of a fluid pressure bearing of a fan having a seat with a through hole for installing a fluid-pressure bearing; wherein a lower bottom of the bearing seat is formed with at least one drain-proof recess; and each drain-proof recess is a closed loop. The form of the drain-proof recess is a closed round recess, a non-round geometrical closed recess, a polygonal closed recess, or any other geometrical closed recess and all the recesses are co-centered with the through hole of the seat. Depths and widths of the drain-proof recesses are identical or not identical. Two adjacent drain-proof recesses are formed with an annular ring, and all the rings are co-centered and have identical or different width.

摘要： A device for rotation of an object disposed on a horizontal surface, about a vertical axis, includes a base for an object, for rotation about a vertical central axis of the base, at low rotational speeds without achieving the gyroscope principle. The base has a lower surface, at least one downwardly projecting, central pivot lug for rotation of the base thereupon and at least one lateral lug spaced radially from the central lug and having a height less than the central pivot lug. The base is configured and dimensioned to rotate when caused to spin while being continuously supported both by the central pivot lug and at least a portion of the lateral lug as it spins. The base is tilted from the vertical axis at a minor angle, with the difference in heights of the central lug and lateral bearing lugs ranging from 0.025 to 1.25 mm.

摘要： A method and system for permanently attaching a take-up screw for taking-up the axial clearance of the armature shaft of a windscreen wiper motor are disclosed. The take-up screw is screwed axially into a bore in the motor base (SM) until the screw reaches a stop position in relation to the armature shaft locked in the screw. At least one surface discontinuity is provided in the bore and/or the thread of the screw, allowing the screw to be screwed into the bore until it reaches the stop position. The screw is screwed into the bore until the stop position is reached and a screw- and/or motor base-deformation strain is applied at the discontinuity in order to deform the side surface of the screw and/or motor base (SM) and permanently attach the screw and/or motor base by wedging in the discontinuity.

摘要： A vapor compression system including a motor having a housing and a shaft having an axis, the shaft urgable into rotational movement by the motor for powering a system component. A primary bearing and a secondary bearing are positioned in the housing for rotatably supporting the shaft, the primary bearing rotatably supporting the shaft during normal system operation. A first bearing stop and a second bearing stop are positioned on opposite sides of the secondary bearing for transmitting axial forces generated along the shaft for reaction by the motor housing during abnormal system operation. At least a portion of corresponding surfaces of each of the first bearing stop and the second bearing stop facing the secondary bearing have a protective overlying layer of material applied thereto.

摘要： A wind turbine yaw assembly has a yaw piston and a yaw bearing pad. A spring resides inside the yaw piston and applies spring pressure to the yaw bearing pad. A threaded yaw piston bushing applies adjustable pressure to the spring. The threaded yaw bushing has a plurality of at least three force adjustment screws distributed symmetrically about the threaded yaw piston bushing. The spring pressure is adjusted by tightening or loosening the plurality of force adjustment screws. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
