Embodiment Construction

[0018] The specific embodiment of the present invention is described in further detail below in conjunction with accompanying drawing:

[0019] See Figure 1-Figure 6 , a permanent magnet transmission device with friction discs, including a driving steel disc 3, a driven steel disc 6, a conductor disc 2, a permanent disc 11, a fixed friction disc 1, a moving friction disc 4, and a centrifugal push module 8. The conductor disk 2 is arranged opposite to the permanent disk 11 , and the fixed friction disk 1 is installed on the active steel disk 3 on the outer ring of the conductor disk 2 . The moving friction disc 4 is combined with the moving friction disc bracket 5 and the inclined-plane cylindrical guide block 7, and is installed on the driven steel disc 6, the outer ring of the permanent disc 11. In a stationary state, the distance between the fixed friction disk 1 and the moving friction disk 4 is greater than or equal to the minimum distance between the permanent disk 11 a...

Abstract

The invention relates to a permanent magnet transmission device with grinding disks. The permanent magnet transmission device comprises a driving steel plate, a driven steel plate, a conductor disk and a permanent magnet disk, wherein the conductor disk is opposite to the permanent magnet disk. The permanent magnet transmission device is characterized in that the outer ring of the conductor disk is provided with a fixed grinding disk, and the outer ring of the permanent magnet disk is provided with a movable grinding disk; a plurality of centrifugal pushing modules are uniformly arranged on the outer side of the driven steel plate in the circumference direction; when the rotating speed of the permanent magnet disk is close to the rated rotating speed, the centrifugal pushing modules generate centrifugal force to push the movable grinding disk and the fixed grinding disk to attract to each other, so that the permanent magnet transmission device transits to the contact transmission of the grinding disks from the non-contact transmission of permanent magnets, the rotating speed of a driven shaft is synchronous with that of a driving shaft, and thus the slip frequency is eliminated; and at that time, due to absence of the slip frequency, the permanent magnet transmission device does not work any more, and the conductor disk cannot generate heat. Compared with the prior art, the permanent magnet transmission device disclosed by the invention has the beneficial effects of keeping the transmission advantages of the permanent magnet transmission structure and being capable of eliminating the slip frequency when the permanent magnet transmission device operates stably at full power.

Description

technical field [0001] The invention relates to a permanent magnet transmission device with a friction disc. When the device is close to the rated speed, centrifugal steel balls push the friction disc to attract and drive the device, which can eliminate the inherent slip of the permanent magnet transmission device and play an energy-saving role. Background technique [0002] At present, in the permanent magnet transmission device, the slip difference between the driving shaft and the driven shaft is at least 2%. The existence of slip is the basis of permanent magnet transmission, and it also brings energy loss. Contents of the invention [0003] The object of the present invention is to provide a permanent magnet transmission device with a friction disc, which can effectively eliminate slippage and avoid heat generation of the conductor disc when the permanent magnet transmission mechanism runs smoothly at full power. [0004] To achieve the above object, the present inve...
