The present invention may provide a motor including a housing, a cover which covers the housing, a stator disposed inside the housing, a rotor disposed inside the stator, a rotary shaft coupled to the rotor, a bearing disposed on the cover, and a nut which is coupled to the cover and which is in contact with an outer ring of the bearing, wherein the cover incudes a first pocket accommodating the bearing and a second pocket which is disposed above the first pocket and to which the nut is rotation-coupled, the nut includes a body disposed to be lower than an upper surface of the cover and including a screw thread and an extension portion disposed to be higher than the upper surface of the cover, the body incudes a protrusion protruding outward from the screw thread, and the second pocket includes a first groove in which the protrusion is positioned.

PERMANENT SCREW ATTACHMENT

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.

HIGH SECURITY FASTENER WITH INTERNAL SHROUD BUCKLED RETAINER

An improved fastener comprising a fastener body orientated about a central axis and having a tool-engaging portion, a threaded fastening portion and a shroud-receiving portion having an inwardly facing annular groove orientated transverse to the central axis; a shroud concentrically mounted on the shroud-receiving portion to rotate relative to the fastener body under an applied external torque and having an axially-buckled radially-extending annular protrusion extending outwardly transverse to the central axis and disposed in the inwardly facing annular groove of the shroud-receiving portion of the body; the axially-buckled radially-extending annular protrusion of the shroud and the annular groove of the shroud-receiving portion of the body forming a shroud-retaining element restraining the shroud from movement in at least a first axial direction along the central axis.

BALL PEEN BOLT
20220034356 · 2022-02-03 ·

A fastener includes a head and a shaft extending from a first end to a second end. The first end is attached to the head. The shaft includes an external thread proximal the second end and a nut having an internal thread and an internal diameter. The second end of the shaft has a first condition and a second condition. In the first condition, an external diameter of the second end corresponds to the internal diameter of the nut such that the internal thread of the nut mates with the external thread of the shaft to attach the nut to the shaft. In the second condition, the external diameter of the second end is greater than the internal diameter of the nut such that the internal thread of the nut does not mate with the external thread of the shaft and the nut, once attached to the shaft, does not detach from the shaft.

High security fastener with external shroud retainer

An improved fastener comprising a fastener body orientated about a central axis and having a tool-engaging portion, a threaded fastening portion and a shroud-receiving portion; a shroud concentrically mounted in the shroud-receiving portion to rotate relative to the fastener body under an applied external torque and having an outwardly extending annular shoulder; the shroud-receiving portion comprising an inwardly deformed stop radially overlapping the outwardly extending annular shoulder of the shroud; and the deformed stop of the shroud-receiving portion and the annular shoulder of the shroud forming a shroud-retaining element restraining the shroud from movement in at least a first axial direction along the central axis.

LOCK NUT
20220136555 · 2022-05-05 ·

A lock nut includes: a first nut having a tapered cavity; and a second nut including a base portion and a tapered lug boss arranged the base portion. The tapered lug boss can be coupled inside the tapered cavity. The first and second nuts are used in pair by self-locking. A straight slot is formed in the lug boss. Under the locking action of the first nut, the straight slot is deformed to further lock a bolt, or is discontinuously engaged with teeth of the bolt to increase an effective stress surface and locking performance of the second nut for locking the bolt. A convex reinforcing rib extends on a first surface of the first nut. An annular groove is formed in a second surface of the second nut. The convex reinforcing rib is coupled with the annular groove to enhance the strength and reliability of locking.

Lower end fitting locknut for nuclear fuel assembly

An apparatus including a lower end fitting having a top planar surface, a bottom planar surface, a counterbore defined therebetween, an opening extending from the counterbore to the top planar surface, and a lock recess that extends both radially outwardly from the counterbore and extends inwardly into the lower end fitting from the bottom planar surface. The apparatus includes a guide tube having a lower end and an end plug configured to connect with the lower end of the guide tube. The end plug has a threaded shaft sized to pass through the opening of the lower end fitting, and a female lock nut has a deformable side wall configured to be swaged into the recess of the lower end fitting. The lock recess remains visible as viewed from the bottom planar surface of the lower end fitting when the female lock nut is fully disposed in the counterbore.

Bracket for wheel speed sensor, and wheel speed sensor

The present disclosure provides a bracket for a wheel speed sensor, and a wheel speed sensor, which can be obtained at low cost and can prevent a bolt from loosening.
