Abstract

The invention aims at providing a magnetic attraction gear transmission mechanism design method used for solving the technical problem of efficient transmission of a magnetic attraction gear. The magnetic attraction gear comprises a magnetic drive wheel and a magnetic driven wheel, wherein a magnetic field coupling direction between the magnetic drive wheel and the magnetic driven wheel is transverse; magnetic transmission torque T changes according to a magnetic meshing period consisting of generating, increasing, reducing and disappearing; and relations between the magnetic transmission torque T and the magnetic gear thickness parameters Lm, the relative rotation angle differences [theta], the relative magnetic conductivities [mu]r, the gear radius parameters r and the coupling air gapsLg of the magnetic drive wheel and the magnetic driven wheel are determined. The magnetic attraction gear transmission mechanism design method provided by the invention has the beneficial effects thatthe contact friction defect of the mechanical gear transmission pair is eliminated, the magnetic attraction gear transmission mechanism design method has the advantages of no friction energy consumption, dispensing with lubrication, being clean, dustproof and waterproof, and being steady in transmission, high in transmission efficiency high in reliability and long in service life; and under the condition of being overloaded, the magnetic drive wheel and the magnetic driven wheel slide and rotate, so that the transmission relation between the magnetic drive wheel and the magnetic driven wheelcan be cut off at any time, so as to play a role in overload protection.

Description

technical field [0001] The invention relates to the technical field of magnetic transmission methods, in particular to a design method of a magnetic gear transmission mechanism. Background technique [0002] Gear is a common mechanism used for transmission. At present, more than 90% of mechanical transmissions use gear transmission, which is a transmission in which gears are mechanically contacted and meshed. It has the advantages of high transmission efficiency and high torque density. Although after a long period of optimization of gear technical parameters, mechanical gears and the use of mechanical gears for transmission have been very mature. However, this kind of mechanical transmission still has problems such as vibration, noise, wear, heat generation, and easy inhalation of dust by lubricating oil, and needs long-term maintenance and maintenance, etc., which cannot be overcome by itself. With the development of mechanical engineering technology, people's requiremen...
