Abstract

The invention relates to the technical field of mechanical and electromagnetic transmission, in particular to an electromagnetic planetary gear which comprises a fixing frame, and a gear ring component, a planetary component and a sun gear component are arranged in the fixing frame. Non-contact gear transmission is achieved through the electromagnetic induction principle, the electromagnetic planetary gear concept is put forward for the first time, a theoretical basis is laid for subsequent research, original theoretical value is achieved, and the engineering significance is that non-contact transmission fundamentally solves the problems of tooth surface abrasion, vibration, noise and lubrication during operation of a mechanical gearbox; the maintenance-free electromagnetic planetary gear has the natural overload protection capability, when the load exceeds the limit torque, only out-of-step oscillation can be caused, the gear cannot be damaged, the locking and tooth breaking phenomena of a mechanical gear are eliminated, and the electromagnetic planetary gear is dual with the mechanical planetary gear in topology and principle and consistent with the mechanical planetary gear in external characteristics. Seamless butt joint with a mechanical planetary gear can be achieved, and the gear box has the potential of replacing a mechanical gear box in part of application occasions.

Description

technical field [0001] The invention relates to the technical field of machinery and electromagnetic transmission, in particular to an electromagnetic planetary gear. Background technique [0002] The traditional mechanical planetary gear is composed of ring gear, sun gear and planetary components. It has the advantages of compact structure, large transmission load, high efficiency and adjustable transmission ratio. It is widely used in aerospace, self-propelled artillery, automobiles, ships, Heavy machinery, metallurgy and many other fields. However, mechanical gears that rely on meshing between teeth to transmit torque inevitably have problems such as friction, vibration, and noise. Their lubrication and cooling systems reduce the reliability of the gearbox while driving up maintenance costs, especially in the field of high-speed transmission. Problems such as wear between teeth, metal fatigue, and elastic deformation are more prominent, and have become important factors ...
