Abstract

The invention discloses a direct-drive gun turret rotating device of frame-free combined type permanent magnet synchronous motor, comprising a fixed base, a gun turret driving rotating table and a driving device. The fixing base is used for bearing the gun tower driving rotating table, and the driving device provides power for the gun tower driving rotating table. The driving device is a framelesscombined type permanent magnet synchronous motor, comprising a stator assembly and a rotor assembly. The stator assembly is fixedly arranged on the fixed base, and the rotor assembly is fixedly arranged on the turret driving rotary table, and a slewing bearing is further arranged between the rotor assembly and the stator assembly. The stator assembly comprises a stator winding and a stator iron core, and the stator winding and the stator iron core are cast into a fan-shaped block which is integrally formed, a plurality of fan-shaped block ring cloth, or is arranged on the rotor assembly in asurrounding mode. According to the invention, the frameless combined type permanent magnet synchronous motor is adopted as a direct driving motor of the device, the middle driving link of the transmission part is reduced, the driving mode and the structure are simplified, the driving efficiency is improved, and direct driving of the device is realized.

Description

technical field [0001] The invention relates to the field of turret and turret rotating equipment, in particular to a frameless combined permanent magnet synchronous motor direct-driven turret rotating device. Background technique [0002] The turrets of tanks, armored vehicles, and engineering vehicles such as excavators need to be rotated. A rotating seat is fixed between the turret and the chassis of the tank and armored vehicle, and between the turret and the chassis of the excavator. On the one hand, it provides a mechanical connection for the turret and the turret, and tightly connects the turret, the turret and the chassis; on the other hand Provide rotational support for the movement of the turret and vehicle tower relative to the chassis. The rotating seat ring includes a chassis connecting ring fixed to the chassis, a rotating ring fixed to the turret or the turret, a bearing ring is fixed between the chassis connecting ring and the rotating ring, and a gear ring ...
