Description

Technical Field

[0001] The utility model relates to the technical field of plastic magnetic rotors, in particular to an anti-deviating plastic magnetic rotor. Background Art

[0002] Injection molded magnetic rotor is a new type of magnetic material, which is made by adding magnetic powder or magnetic fiber to a non-metallic matrix. Compared with traditional magnetic materials, injection molded magnetic rotor has low density, poor conductivity and good corrosion resistance, so it can replace traditional metal magnetic materials in some special occasions.

[0003] As the use time increases, the surface of the shaft is gradually worn, causing the rotation of the shaft to deviate. When the surface of the shaft is worn, the eccentric motion will damage the rotor. Existing equipment can only solve the problem by replacing a new rotor, which is costly and inconvenient.

[0014] Preferably, the inner shaft surface of the bearing is fixedly connected to the outer surface of the turntable, the connecting shaft is arranged in the arc-shaped opening of the turntable, one end of the connecting shaft passes through the inner wall surface of the protective shell, and the connecting shaft and the protective shell are rotatably connected.

[0015] The adoption of the technical solution facilitates the rotation of the turntable.

[0016] Preferably, the width of the rack is the same as the width of the rectangular opening at the lower end of the protective shell, one side surface of the slide rail is fixedly connected to the inner wall surface of the protective shell, and the other end of the spring is fixedly connected to the inner wall surface of the protective shell.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the anti-deviating plastic magnetic rotor:

[0019] 1. The clamping mechanism facilitates the stable operation of the rotating shaft. As the use time increases, the surface of the rotating shaft is gradually worn, causing the rotation of the rotating shaft to deviate. When the surface of the rotating shaft is worn, the turntable starts to rotate. As the turntable rotates, the slider 2 makes a spiral motion on the slide groove 2, and the slider 1 makes a linear motion on the slide groove 1 at the same time, so that the roller surface is always in contact with the surface of the rotating shaft. This mechanism can prevent the deviation caused by the wear of the rotating shaft.

[0020] 2. The adjustment mechanism can automatically keep the rotating shaft and the roller surface in contact at all times. When the rotating shaft is worn, the rack is pushed downward by the spring, causing gear 2 to rotate. Gear 1 rotates at the same time, and the ring gear also rotates at this time, thereby providing a structural basis for the clamping mechanism to always keep the rotating shaft and the roller surface in contact. This mechanism can automatically keep the rotating shaft and the roller surface in contact at all times and is easy to maintain and disassemble. BRIEF DESCRIPTION OF THE DRAWINGS
