A coil spring unit includes a coil spring; and a metal plate supporting the coil spring, the metal plate including a plurality of supporting portions cooperative with each other to support the coil spring, wherein the supporting portions are provided by bending the metal plate at bending lines and have supporting surfaces substantially perpendicular to the bending lines, respectively, and wherein the supporting surfaces are substantially parallel with outside tangential lines of the coil spring and support the coil spring.

A torque limiter assembly is disclosed comprising a housing having at least one first engagement member, an input shaft that is rotatable relative to the housing and having at least one second engagement member; and an electromagnet. The electromagnet 10 is arranged and configured such that when activated it generates a magnetic field that moves the at least one first engagement member relative to the at least one second engagement member, such that the first and second engagement members engage each other and stop or inhibit rotation of the input shaft relative to the housing.

A torque limiter includes a first meshing portion provided at a surface of an input shaft which transmits a drive force of a drive motor, the surface intersecting with an axial direction of the input shaft, and a disc spring portion including a second meshing portion arranged facing the first meshing portion in the axial direction and which is configured to mesh with the first meshing portion. The disc spring portion is integrally rotatable with an output shaft which is provided coaxially with the input shaft and which is rotatable relative to the input shaft, and is deflected to displace the second meshing portion in a direction opposite to the first meshing portion in a case where a load equal to or greater than a set value is applied to the disc spring portion while the second meshing portion is being biased towards the first meshing portion.

The disclosure relates to an overload clutch, comprising a cylindrical clutch housing having a housing body and a housing cover, and comprising two clutch elements arranged within the clutch housing, via which a drive movement is transmissible in an engaged state, wherein the clutch elements, for transmitting the drive movement in the engaged state, are engaged with each other in an interlocking and/or frictional manner and, can be brought out of engagement when an overload occurs. The housing body comprises a plurality of engagement elements, and the housing cover comprises a plurality of retaining structures corresponding to the engagement elements, wherein the engagement elements are able to be brought into engagement with the retaining structures by rotating the housing cover relative to the housing body.

Crest-valley repeated shapes that are fitted to each other by a biasing force of a spring are disposed so as to be opposed to each other in opposed surfaces that are opposed to each other and rotate relative to each other between a view device base side and a view device rotating section side. Respective height maintaining protrusions are disposed so as to be opposed to each other in the opposed surfaces. Upon the view device rotating section being rotated from an extended position toward a forward-tilted position by an external force, respective top surfaces of the height maintaining protrusions are brought into abutment with and slide on each other in a position in which abutment between respective top surfaces of the crests of the crest-valley repeated shapes is cancelled, to maintain a height of the view device rotating section.

A torque limiter includes a first meshing portion provided at a surface of an input shaft, a plate including a second meshing portion which is configured to mesh with the first meshing portion, and a disc spring portion integrally rotatable with an output shaft. The disc spring portion includes an engaging portion engaging with the plate. The disc spring portion is deflected to displace the engaging portion in a direction opposite to the plate in a case where a load equal to or greater than a set value is applied to the disc spring portion while pressing the plate via the engaging portion so as to bias the second meshing portion towards the first meshing portion.

Torque limiting connectors are described herein. A torque limiting connector includes an outer connector, and inner connector, and a clutch. The outer connector includes a profile disposed on an inner surface of the outer connector. The inner connector may be disposed within the outer connector and can include an upper threaded portion and a lower threaded portion. The clutch can be disposed around and rotationally coupled to the inner connector and can include a plurality of clutch teeth extending from an outer surface of the clutch, wherein the plurality of clutch teeth are outwardly biased to be releasably engaged with the profile of the outer connector. The plurality of clutch teeth can be configured to transfer torque from the outer connector to the inner connector when the torque is below a torque limit, and prevent transfer of torque when the torque exceeds the torque limit.

A device for blocking a fin of a projectile, the fin including a fin base pivoting about a pivot pin secured to the body of the projectile between a withdrawn fin position and a deployed fin position, wherein the device includes at least one recess housing at least one shape of revolution pushed by a resilient means between a first surface borne by the fin and a second surface borne by the body of the projectile, at least one of the two surfaces forming a ramp that converges toward the other surface to tend to cause jamming of the shape of revolution between the two surfaces.

A torque limiting assembly is disclosed comprising: an input shaft; an output shaft; a drive bush; a motion converter mechanism; a casing; and at least one engagement member for engaging the casing. In a low torque mode, rotation of the input shaft drives rotation of the drive bush, motion converter mechanism and output shaft. In a high torque mode, rotation of the motion converter mechanism relative to the output shaft urges the motion converter mechanism axially to drive rotation of the drive bush relative to the input shaft. The engagement member is coupled to both the drive bush and the input shaft such that when the drive bush is rotated relative to the input shaft, the engagement member is urged to engage the casing so as to prevent or inhibit rotation of the input shaft relative to the casing.
