Problems solved by technology
And because there is a shaft, there is bound to be a possibility of eccentricity, which will increase wear and reduce service life
Shafted rollers mainly have the following disadvantages: there are certain requirements on the material of the shaft; friction between rotating parts and fixed parts will cause wear and noise; eccentricity cannot be avoided, which will make the wear and noise problems more serious and reduce the service life
However, the shaftless roller will still be fixed on the device, and the driving device will drive the roller to rotate. For example, the wheel drive drives the roller through a gear-like drive, and the chain drive drives the roller through a chain or a belt. Contact will still cause wear and noise. , thereby reducing the service life

The invention relates to a non-contact shaftless roller and an installation and control method thereof. The non-contact shaftless roller comprises an outer cylinder and an inner cylinder, and the outer cylinder comprises an outer cylinder body and outer cylinder baffles located at the two ends of the outer cylinder body; an outer cylinder body magnet is arranged on the arc-shaped wall of the outer cylinder body; an outer baffle plate magnet is arranged on the outer cylinder baffle plate; the inner cylinder comprises an inner cylinder body and inner cylinder baffles located at the two ends of the inner cylinder body. An inner cylinder magnet is arranged on the arc-shaped wall of the inner cylinder body, and an inner baffle magnet is arranged on the inner cylinder baffle. The rotor does not need to be fixed with other structures, so that the installation is convenient; the structure is not easy to wear, and the service life is prolonged.
Description
technical field [0001] The invention relates to the technical field of rotors, in particular to a non-contact shaftless roller and an installation and control method thereof. Background technique [0002] The drum structure is widely used in various mechanical devices, such as washing machines, conveyors, shredding machines, mining machines, separation and extraction devices, etc. Rollers can be divided into two types: shafted and shaftless. [0003] The mandrel of the shafted roller will be subjected to loads and may be subjected to various bending moments and torques, and the shaft will inevitably generate pressure between the rotating part and the fixed part, which will cause friction during rotation, which will wear the parts and also produce noise. Although the device will take various lubricating measures in actual work, it will still inevitably cause loss and noise. Therefore, the material of the shaft is generally limited and needs to be processed. At present, ro...
