Problems solved by technology

However, the error of the ring gear is an important factor causing the error of the planetary gear. In order to ensure the accuracy of the operation of the planetary gear, the inner ring gear is usually required to have higher machining accuracy, which increases the difficulty of production and processing.

Abstract

The invention discloses a gear ring-free planetary magnetic gear speed changing system. The gear ring-free planetary magnetic gear speed changing system comprises a gear ring-free planetary gear portion, a magnetic gear portion and a speed changing portion. The gear ring-free planetary gear portion comprises an input end planet carrier, an output end planet carrier, four groups of solar magnetic gears and planetary magnetic gears, and then gear ring-free planetary gear transmission can be achieved; the magnetic gear portion is made of a permanent magnet, magnetic poles are evenly distributed,and magnetic gear transmission is achieved through the opposites attract action; and the speed changing system comprises pushing rods, synchronizers, an input shaft and the solar magnetic gears, therefore, the purpose that the pushing rods control work of the synchronizers can be achieved, and the input shaft is connected with the four solar gears to generate different transmission ratio changes.The novel speed changing system has the advantages that overload protection is achieved, cleanliness and environmental friendliness are achieved, the machining requirement is low, the transmission ratio is large, the speed changing method is simple, the speed changing range is wide, and the usage occasion is wide.

Description

technical field [0001] The invention relates to a gearless planetary magnetic gear transmission system. Background technique [0002] The transmission is a mechanism used to change the speed and torque from the input end, and it can change the transmission ratio of the output shaft and the input shaft. Traditional transmissions usually adopt gear transmission, which has certain shortcomings. On the one hand, ordinary gear transmission will produce vibration, noise, wear and heat due to its transmission characteristics, and dust, powder, etc. will affect the lubrication performance. On the other hand, ordinary gear transmission has certain shortcomings in terms of load capacity, output torque, output efficiency, and reliability. The design purpose of the present invention is to improve these defects of the transmission. [0003] Planetary gears are widely used in improving load capacity, output torque, and output efficiency. Compared with ordinary gear sets, planetary gea...
