Center positioning multi-layer permanent magnet governor

Abstract

The invention provides a centralized positioning multilayer permanent magnet governor. A motor shaft is connected with a conductor plate; a load shaft is connected with a magnet plate through an adjusting mechanism; the adjusting mechanism is used for adjusting the coupling area between a conductor and a magnet; the conductor plate is evenly provided with conductor rings; the conductor rings are symmetrically arranged around the circle center of the conductor plate as the center; a load plate is evenly provided with magnet rings; the magnet rings are symmetrically arranged around the circle center of the magnet plate as the center; the magnet rings and two adjacent conductor rings are arranged in a manner of one-to-one correspondence; the quantity of the magnet rings is one half of that of the conductor rings; the quantity of the conductor rings is multiples of 2; the conductor plate is also provided with a conductor bearing; the magnet plate is also provided with a magnet bearing; the conductor bearing and the magnet bearing are in mutual contact; and a positioning device is arranged between the conductor bearing and the magnet bearing. The centralized positioning multilayer permanent magnet governor has the beneficial effects of being smaller in size, lighter in weight, higher in service power and better in energy-saving effect, and the overall design is more optimal.

Description

technical field [0001] The invention relates to the technical field of drive speed regulating machinery, and more specifically relates to a centrally positioned multilayer permanent magnet speed regulator. Background technique [0002] In recent years, a speed control device has been invented in China, which is mainly composed of a permanent magnet ring and a set of conductor rings, which transmits the rotation from the motor to the load, and realizes the change of the transmitted speed and power with the change of the coupling area, but Due to the need to transfer energy, the diameter of this single-layer structure is very large, especially if the motor power is large, which will lead to excessive self-weight, excessive consumables, and increase heat generation and self-energy consumption. Furthermore, the noise is large and the mechanism stability is poor, so that this device cannot be applied to high-power equipment. [0003] The main part of the permanent magnet speed r...

Problems solved by technology

The two shafts are not rigidly connected, and the formation of a cantilever beam structure with two arms lengths of 300-500mm is unavoidable (the weights of the two discs mounted on the shaft end are both 50-80kg); it is very easy to cause radial deformation of the shaft, so Shaft alignment is a difficult point in the installation of this equipment

Although this structure has a certain tolerance for coaxiality (limited to 3mm), even within this limit, this error will cause the magnetic field induced by the magnet ring to be uneven, which will affect the unevenness of the eddy current generated. Seriously affect the energy saving effect of the machine

If the error exceeds the tolerance, it will cause the parts to collide and cause an accident
