Handwheel mechanism with adjustable torque

Abstract

The invention discloses a handwheel mechanism with an adjustable torque. A way of compressing elastic elements by a first bolt is used; and different groups of elastic elements are installed (based on a second bolt-spring-bush-steel ball structure) and the screwing depth of the second bolt is adjusted, so that spring forces of the elastic elements can be changed and thus the handwheel torque can be adjusted. Therefore, different using demands can be satisfied and the product application range is enlarged. According to the ahndwheel provided by the invention, the structure containing steel balls, steel ball support plates, and steel ball holding plates is used for replacing the traditional rim rolling structure. During assembling, a handwheel body, the structure containing steel balls, steel ball support plates, and steel ball holding plates, a handwheel ring, a cover plate and a first bolt are successively installed at the forward direction; and when the second bolt-spring-bush-steel ball structure is installed in an inverted mode. The installation becomes convenient and rapid; repeated dismounting and parts replacement of the handwheel assemblies can be realized; and the product maintainability is enhanced.

Description

Technical field [0001] The invention relates to a torque transmission device, in particular to a torque adjustable handwheel mechanism, which is used to separate and fall off electrical connectors and other occasions that need to transmit torque, and can adjust the maximum output torque. It belongs to mechanical design technology. Background technique [0002] The hand wheel is a power transmission device that separates and falls off 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 in place, the handwheel is required to slip, that is, the torque transmitted by the handwheel will no longer increase, which can play a role in overload protection for the external transmission mechanism. Since different electrical connectors require different mating power to be mated in place, a handwheel mechanism capable of transmitting different torque forces is requ...

AI Technical Summary

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
