Embodiment 1

[0032] As shown in the figure, a magnetic levitation planetary transmission speed changer includes an I shaft 1, a housing 5, an II shaft 9, and a permanent magnet 14. The inner side of the housing 5 is provided with an inner ring gear 6, and the inner ring gear 6 is provided with straight grooves, the number is 12, and permanent magnet mounting frame I7 is arranged in the straight grooves, and end caps 3 are provided at both ends of the housing 5, and the center of the end caps 3 at one end of the housing 5 is connected to the input through the bearing 2 The connecting shaft 4, the center of the end cover 3 at the other end is connected to the II shaft 9 through the bearing 2, one end of the I shaft 1 is installed at the center of the input connecting shaft 4, and the other end is installed at the center of the II shaft 9, and the I shaft 1 is equipped with an eccentric shaft 11 through a key, and the eccentric shaft 11 is connected to the planetary wheel 13 through a bearing....

Embodiment 2

[0035] The difference from Embodiment 1 is that the permanent magnets 14 on the permanent magnet mounting frame I7 and the permanent magnet mounting frame II8 are arranged in a Halbach manner, and the magnetism is mutual repulsion.

[0036] This embodiment can accomplish greater torque transmission than Implementation 2.

Embodiment 3

[0038] The difference from Embodiment 1 or 2 is that the pitch of the straight grooves of the ring gear 6 is equidistant, and the number is three, and the pitch of the straight grooves on the planetary gear 13 is equidistant, and the number is two.

Description

technical field [0001] The invention relates to a planetary transmission speed reducer, in particular to a magnetic levitation planetary transmission speed changer. Background technique [0002] The traditional gear transmission mechanism mainly relies on the meshing force of mechanical gears to realize the transmission of torque and speed. At the moment of its transmission, only two teeth contact to do work, which will cause wear, noise, vibration, and other teeth do not do work. The utilization rate is low, and at the same time, in order to ensure the operation of the system, lubricating oil needs to be added for lubrication and cooling, which is easy to pollute the environment. Therefore, traditional gear drives cannot be used in some special environments, such as food manufacturing, aerospace and other fields. [0003] In order to solve the shortcomings of traditional gear transmission, inventors in the last century have proposed magnetic levitation transmission using e...
