6 results about "Limiter" patented technology

The invention discloses a speed limiter of a monorail conveyor. The speed limiter of the monorail conveyor comprises a brake drum and a brake mechanism, wherein the brake drum is fixedly arranged on the rack, and the brake mechanism is arranged in the brake drum; the inner circular surface of the brake drum is located outside a brake demarcation circle; the braking mechanism comprises a rotating frame and two sets of braking assemblies arranged on the rotating frame, the center of the rotating frame is connected with a running rotating shaft of the monorail conveyor, the two sets of brake shoes are symmetrically arranged on the rotating frame, and each set of braking assemblies comprises two brake shoes and an elastic element; two brake shoes of each set of brake assemblies are symmetrically arranged, and one end, far away from each other, of the two brake shoes is connected with the rotating frame in a rotating mode, and the brake shoe is always located in the brake demarcation circleunder the action of the elastic element. No matter whether the operation rotating shaft of the monorail conveyor rotates forwards or backwards is reversed, the speed limiting effect of the speed limiter of the monorail conveyor is the same, so that the device can be adapted to different types of equipment and is flexible to install.

The invention discloses a domestic small-sized multifunctional shoe cabinet, comprising a cabinet body and draw-out boxes; slides in two tiers are arranged in the cabinet body; the draw-out boxes are mounted on the slides; each draw-out box comprises a meshed partition, rollers, a cover plate and a handle, the handle is fixed to the outer side of the cover plate, the inner side of the cover plate is perpendicularly connected to the outer end of the meshed partition, and four corners of the bottom of the meshed partition are provided with the rollers symmetrically; two rollers on the left of the bottom of each meshed partition are mounted in a slide groove of the corresponding left slide in sliding fit manner, and the two rollers on the right of the bottom of each meshed partition are mounted in a slide groove of the corresponding right slide in a sliding fit manner; the outer ends of the left and right slides are provided with limiters correspondingly, the limiters on each left slide are positioned between the two rollers on the left of the bottom of corresponding meshed partition, and the limiters on each right slide are positioned between the two rollers on the right of the bottom of the corresponding meshed partition. The domestic small-sized multifunctional shoe cabinet is simple in structure, convenient to use and low in manufacture cost.

The invention discloses an artificial muscle device which comprises a coil framework, wherein a first permanent magnet is movably inserted into the inner side of the coil framework; a first electromagnetic coil is wound around the outer side of the coil framework; a magnetic yoke is arranged on the outer side of the first electromagnetic coil; a limiter is fixed on the first permanent magnet; thelimiter and the magnetic yoke are in sliding contact with each other; a sliding groove is formed in the surface of the magnetic yoke; a plurality of electromagnetic dampers are arranged on the contract surface between the limiter and the magnetic yoke; each electromagnetic damper and the sliding groove are in selective contact with each other; the electromagnetic dampers and the first electromagnetic coil are connected onto one and the same main power supply controller; and a branch power supply controller is independently arranged on each electromagnetic damper. By adoption of the artificialmuscle device disclosed by the invention, defects in the prior art can be overcome, and the motion control accuracy of electromagnetically-driven artificial muscle can be improved.

The invention discloses a gapless gear transmission multifunctional limiter, which is characterized by comprising a seat plate component (1), a first gear component (8) and a second gear component (12). The upper end of the first gear component (8) is fixedly mounted on the seat plate component (1), and the first gear component (8) is coaxially connected with a gear of a worm gear component (7) via a bearing (9). Gears of the first gear component (8) and the second gear component (7) are metal gears, and flexible materials are attached on the surfaces of the metal gears. The gapless gear transmission multifunctional limiter is high in precision, gapless transmission of the gears can be realized, error accumulated risks are reduced, and cost is low.
