    摘要： 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.

    摘要： 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 including an engaging portion engaging with the plate, the disc spring portion 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.

    摘要： A clutch assembly for a toy includes a clutch disc member and an inserting member. The clutch disc member includes a central opening and a plurality of seats distributed in a circular pattern. The inserting member includes a plurality of wedges distributed in a circular pattern. The seats and the wedges are designed to (A) engage the wedges in the seats when a force exerted between a driving element operably connected to the clutch disc member and a driven element operably connected to the inserting member is less than a predetermined force level, and (B) automatically disengage the wedges from the seats when the force exerted exceeds the predetermined force level, and (C) re-engage again when the excessive force is released so as to fall below the predetermined force level after slippage of the wedges out of the seats.

    摘要： A compact clutch including a driven shaft on which the following are mounted: a gear wheel; a driving bush; a driven bush; a coil spring; a first collar with cam surfaces; and a second collar with cam surfaces. The gear wheel and the bushes are arranged axially next to each other; the gear wheel and the driving bush are constrained together in the circumferential direction; the spring surrounds externally the bushes; the first collar surrounds externally the spring; and the second collar surrounds externally the first collar. The gear wheel and the bushes are constrained to the driven shaft in the axial direction by means of two stop rings; and the driven bush is constrained to the driven shaft in the circumferential direction by means of at least one tongue.

    摘要： A torque limiting apparatus is provided having an input shaft, an output shaft, a housing, a spring, and a length adjustable shank and collar assembly. The input shaft communicates with a rotating end segment having a cam surface. The output shaft communicates with a rotating end segment having a complementary cam surface for engaging with the cam surface of the input shaft. The cam surfaces cooperate to generate separation forces between the respective rotating end segments. The housing encases the first end segment and the second end segment. The spring is supported in the housing, and is configured to oppose the separation forces generated by the cam surfaces, and is configured to urge together the first end segment and the second end segment to remain in rotating coupled engagement. The length adjustable shank and collar assembly is provided between the spring and the housing and is configured to adjust compressive force on the spring to change torque output of the apparatus. A method is also provided.

    摘要： Transmission device for self-propelled equipment, includes a housing having a driving input shaft transmitting movement to an output shaft, the input shaft bearing a receiving pulley around which pulley a belt transmission is wrapped. The input shaft also bears a component that rotates as one with the shaft and a member for controlling the movement of the pulley along the input shaft in terms of the pulley movement towards or away from the component so that the pulley, which is mounted with freedom to rotate on the input shaft, can be moved from a disengaged position when it is away from the component, into an engaged position when it is close to the component, the pulley having a groove of constant predetermined width for accepting the belt so that when the belt is taut inside the groove, the belt tension is maintained as the pulley moves along the input shaft.
