Helical gear transmission 360-degree dual-axis synchronous damping shaft

Abstract

The present invention discloses a helical gear transmission type 360 DEG double-shaft synchronous damping rotation shaft, which comprises two shaft cores and at least two connection plates, wherein active helical gears are arranged corresponding to each shaft core, each active helical gear is sleeved and fixed on the corresponding shaft core, the two connection plates are positioned on both sides of the two helical gears and are sleeved on the two shaft cores so as to radially separate the two shaft cores and set the distance, the two shaft cores can subjected to axial stopping and circumferential free rotation relative to the two connection plates, a transmission helical gear is arranged and is positioned in the receiving space enclosed by the two connection plates and the two active helical gears, and both ends of the transmission helical gear are respectively engaged with the two active helical gears. According to the present invention, with the less active helical gear parts, the synchronous 360 DEG rotation opening and closing and the limitless flipping function of the double shafts can be achieved, and the connection of the rotation position is perfect and smooth.

Description

technical field [0001] The invention relates to a damping rotating shaft, in particular to a helical gear transmission type 360-degree dual-axis synchronous damping rotating shaft. 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 functions of 360-degree opening and closing, positioning and automatic closing of the notebook computer are realized by positioning the cam and concave wheel sleeved on the single-axis core. There are also the functions of opening and closing, positioning and automatic closing of the notebook compute...

Problems solved by technology

There are also the functions of opening and closing, positioning and automatic closing of the notebook computer through the dual-axis core structure; 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. , the operation is not yet perfect, and it is impossible to achieve synchronization

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. The function of double-axis synchronous reverse opening and closing, and the use of more gears limits the development of thinner electronic equipment such as notebooks, and the installation and removal operations are more cumbersome
