Worm gear transmission type 360-degree dual-axis synchronous damping shaft

Abstract

The invention discloses a worm gear transmission type 360-degree dual-axis synchronous damping rotating shaft, which includes two shaft cores and at least two connecting plates. A first worm and a second worm wheel are respectively provided on one of the two shaft cores. There are first worm gears and second worm gears; each first worm gear or second worm gear is fixed on the corresponding shaft core, and two connecting plates are positioned at both ends of the two first worm gears or second worm gears and are sleeved On the two shaft cores, the two shaft cores are radially spaced by a set distance, and the two shaft cores can rotate freely in the circumferential direction with axial stop relative to the two connecting plates; the first worm gear or the second worm screw is positioned on both sides. In the receiving space surrounded by two connecting plates and two first worm gears or second worm gears, radially opposite sides of the first worm gear or second worm gears are meshed with the two first worm gears or second worm gears respectively. The invention can realize dual-axis synchronous 360-degree rotation opening and closing and unlimited flip functions, and can connect the rotating parts more perfectly and smoothly.

Description

technical field [0001] The invention relates to a damping rotating shaft, in particular to a 360-degree dual-axis synchronous damping rotating shaft of a worm gear transmission type. Background technique [0002] The damping shaft is a connecting element that can provide mutual rotation. It is mainly used between the rotating parts and its base. At present, it is widely used in various digital products and electronic equipment, such as notebook computers. The rotation of the damping shaft can realize The opening and closing function between the body of the notebook computer and the display screen. At present, the commonly used rotating shaft is usually a single-axis core, and the 360-degree opening and closing and positioning functions of the notebook computer are realized by positioning the torsion unit sleeved on the single-axis core. There is also a dual-axis core structure to realize the opening and closing and positioning functions of the notebook computer; however, th...

Problems solved by technology

There is also a dual-axis core structure to realize the opening and closing and positioning functions of the notebook computer; however, this dual-axis core structure is usually that when one shaft core rotates, the other shaft core is locked, and the two shafts are sequentially opened and closed. Imperfect, cannot be synchronized

In order to achieve 360-degree synchronous rotation of the two shafts, there are also biaxial hubs that use multiple gears for combined transmission. The axes of the multiple gears are in the same direction as the axes of the two shafts. Dual-axis synchronous reverse opening and closing functions smoothly, and due to the use of more gears, the development of thinner electronic equipment such as notebooks is limited, and the installation and removal operations are more cumbersome
