Detailed Description
The present invention will be further explained with reference to the drawings and examples.
With reference to fig. 1 to 4, the embodiment of the magnetic gear of the electromagnet of the present invention includes a wheel disc 1 and convex wheel teeth 2; rectangular square grooves are respectively formed in two tooth surfaces of the convex gear teeth, an electromagnet 3 consisting of an iron core 32 and a coil 31 is embedded in each square groove, the electromagnet is provided with a square shell (not shown) made of electrician pure iron, the shell is fixed in each square groove through a set screw 8, the outer surface of the shell is level to the tooth surfaces of the gear teeth, and residual magnetism does not exist after power failure; the coil of the electromagnet adopts a national standard red copper coil with good temperature stability, so that the heat generated in the working process of the gear cannot influence the whole device; the electromagnet structures (the size of an iron core and the number of turns of a coil) on two tooth surfaces are the same, the coils are mutually connected in series, the electromagnets on two tooth surfaces of two adjacent convex gear teeth which are opposite are the same in polarity and the same in size, and a lead wire (not shown) of each coil is embedded in a wiring groove 4 formed in the end surface of a wheel disc and is gathered at the axis of the gear and then connected with a conducting ring 52 of an electric slip ring through an annular electric brush 51 of the electric slip ring 5; the annular electric brush of the electric slip ring is made of silver carbon fiber, is elastic and filamentous, has small resistance, can be effectively contacted with the conducting ring, and ensures that the electromagnet can continuously supply power in the high-speed transmission process of the gear.
