Example Embodiment
[0028] Example 1: See attached Figure 1-3 , The present invention provides a low-speed high-torque permanent magnet motor direct-drive ball mill system, which includes a barrel 1, a first support shaft 2 and a second support shaft 3 arranged at both ends of the barrel 1, respectively and the first support shaft 2 and the second supporting shaft 3 installed the first bearing housing 4 and the second bearing housing 5 and the permanent magnet motor 6 directly connected to the second supporting shaft 3, the key lies in: the bottom of the permanent magnet motor 6 is equipped with self-adaptability Flexible positioning device. The adaptive flexible positioning device includes a support base 7 and a buffer spring 8 and a damper device arranged between the support base 7 and the permanent magnet motor 6. The buffer springs 8 are provided in multiple and divided into two groups It is symmetrically arranged on both sides of the damper device.
[0029] In this embodiment, the damping devi...
Example Embodiment
[0038] Example 2: See attached Figure 8 The difference from the first embodiment is that the first supporting shaft 2 is also an elongated structure and is directly connected to the permanent magnet motor 6, and the bottom of the permanent magnet motor 6 is also provided with an adaptive flexible positioning device. The driving of the two permanent magnet motors 6 makes the rotation process of the cylinder 1 more balanced.
Example Embodiment
[0039] Example 3: See attached Picture 9 The difference from the first and second embodiments is that the permanent magnet motor 6 is directly connected to the cylinder 1, and the bottom of the permanent magnet motor 6 is provided with an adaptive flexible positioning device.
