Problems solved by technology

[0003] At present, there are more and more types of tower crane rotating devices, their functions are becoming more and more perfect, and their structures are becoming more and more complex. However, their driving devices are generally composed of transmission devices such as motor gears and connecting rods. Efficiency and accuracy are greatly lost. At the same time, due to the increase in the number of transmission components, the performance is affected, which also leads to increased difficulty in design, manufacturing and assembly, and increased costs.

Description

technical field [0001] The invention relates to the technical field of workpiece processing equipment, in particular to a tower crane rotating device directly driven by a frameless permanent magnet synchronous motor. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as tower cranes. It is used to hoist construction materials such as steel bars, wooden corrugations, and scaffolding pipes. It is an indispensable equipment for construction sites. . The function of the tower crane is to bear the upper load transmitted from the jib stay rope and the balance jib stay rope, and transmit it directly to the tower structure through the turntable through the structural components such as the slewing tower, turntable, and bearing. Among them, the rotating device of the tower crane is the most important part, which needs to bear the rotating, radial and axial loads. [0003] At present, there are more and more types ...
