Abstract

The invention discloses an outer rotor magnetic flux collecting magnetic gear. The magnetic gear has an axial structure, and the section of the magnetic gear comprises a magnetic gear outer rotor, a magnetic flux adjusting ring and a magnetic gear inner rotor from outside to inside in sequence; the magnetic gear outer rotor, the magnetic flux adjusting ring and the magnetic gear inner rotor are coaxial and are independent of one another; an outer air gap (3) is formed between the magnetic gear outer rotor and the magnetic flux adjusting ring; an inner air gap (6) is formed between the magnetic flux adjusting ring and the magnetic gear inner rotor; the magnetic gear outer rotor and the magnetic gear inner rotor freely rotate and are connected with a driving or driven component to perform torque transfer respectively; and the middle magnetic flux adjusting ring is in a stationary state and is fixed at the two axial ends. Through the outer rotor magnetic flux collecting magnetic gear, the torque transfer capacity of the magnetic gear can be improved.

Description

technical field [0001] The invention relates to an outer rotor magnetic gathering type magnetic gear, which is suitable for non-contact variable speed driving occasions. The invention relates to the fields of motors and machinery. Background technique [0002] In industrial applications, many occasions that require variable speed drives are usually realized by mechanical devices such as bulky gearboxes. The use of a large number of mechanical devices will inevitably bring about problems such as noise, vibration, friction loss and regular maintenance, and will significantly increase the complexity, volume and weight of the system. In addition, mechanical gears do not have overload self-protection capabilities, and safety accidents are prone to occur when the transmitted torque exceeds the gear's bearing capacity. [0003] In contrast, the magnetic gear is a non-contact transmission device, which does not have problems such as noise, vibration, friction loss, and lubrication,...
