Abstract

The invention relates to a tire balancing device, in particular to a self-driven balancing machine rotating component and a corresponding tire balancing machine. The existing tire balancing machine has a complicated structure and low efficiency, is inconvenient to manufacture, and has transmission error. The self-driven balancing machine rotating component comprises an outer rotor and an inner stator, which are both fixed on the same axis. The self-driven balancing machine rotating component has large torque, high efficiency and convenient control, and is suitable for various balancing machines; and the tire balancing machine assembled with the rotating component has accurate detection, and is suitable for being used for balancing various tires.

Description

technical field [0001] The invention relates to a tire balancing device, in particular to a self-driven balancing machine rotating assembly and a corresponding tire balancing machine. Background technique [0002] The tire balancers produced by various manufacturers in the market today use an external motor to drive the rotating assembly to drive the wheel being balanced to rotate. There are mainly two types of indirect drive and direct drive. There are two forms of indirect drive: 1. Driven by a pulley; 2. Driven by a clutch roller. [0003] The direct drive scheme that has been announced so far is that the inner rotor of the motor directly drives the rotating main shaft through a shaft connection. There is no tire balancing machine directly driven by a permanent magnet brushless DC motor, which has complex structure, low efficiency, inconvenient manufacture, and transmission error. Contents of the invention [0004] The technical problem to be solved by the present inv...
