A Torque Adjustable Handwheel Mechanism

Abstract

The invention discloses a torque adjustable handwheel mechanism. The present invention adopts the first screw to compress the elastic element, and by installing different groups of elastic elements (second screw-spring-bush-steel ball structure) and adjusting the screw-in depth of the second screw, the elastic element can be changed. The spring force can realize the adjustment of the torque of the hand wheel, which can meet different usage requirements and expand the application range of the product. The handwheel designed by the present invention adopts the structure of steel ball-steel ball supporting piece-steel ball holding piece instead of the traditional crimping structure. When assembling, first install the handwheel body, steel ball-steel ball supporting piece-steel ball holding Plate structure, hand wheel ring, cover plate and first screw, and then install the second screw-spring-bush-steel ball structure by flip-chip method, which is convenient and simple to install, and can realize repeated disassembly and parts replacement of the hand wheel assembly. Improved product maintainability.

Description

technical field [0001] The invention relates to a torque transmission device, in particular to a torque-adjustable handwheel mechanism, which is used in other occasions that require torque transmission, such as separating and falling off electrical connectors, and can adjust the maximum output torque of the handwheel mechanism, which belongs to mechanical design technology. Background technique [0002] The hand wheel is a power transmission device for separating and disconnecting the electrical connector, and the power is provided for the insertion and separation process of the electrical connector by rotating the hand wheel. When the plug and the socket are mated in place, the hand wheel is required to slip, that is, the torque transmitted by the hand wheel does not increase, and it can protect the external transmission mechanism from overload. Since different electrical connectors require different mating forces to be mated in place, a hand wheel mechanism capable of tra...

Problems solved by technology

Once the traditional handwheel mechanism is assembled, the maximum torque that can be transmitted is a pre-designed constant value, which cannot be adjusted in real time according to the needs of the site.

Different electrical connectors have different torque requirements, so different handwheel mechanisms need to be designed, resulting in waste of resources and reducing the use efficiency of equipment. It is urgent to design a torque-adjustable handwheel mechanism
