The invention relates to the field of arm supports, and discloses a rotary driving mechanism, an arm support and engineering machinery, the rotary driving mechanism comprises an annular piston (10) and a stator, the annular piston (10) is provided with a piston tooth part with a protruding bent tooth surface and a piston tooth part with an inclined flat tooth surface, the stator is provided with stator teeth with protruding curved tooth surfaces and stator teeth with inclined flat tooth surfaces, and the annular piston (10) can be driven to move axially relative to the stator. According to the technical scheme, meshing of the bent tooth surfaces and meshing of the flat tooth surfaces are combined, stable transmission at the beginning meshing stage can be guaranteed, noise is lower, axial movement can be converted into uniform-speed rotation at the subsequent meshing stage, and more stable torque output is provided.
本发明涉及臂架领域,公开了一种旋转驱动机构、臂架及工程机械,所述旋转驱动机构包括环形活塞(10)和定子,所述环形活塞(10)设置有具有突出的弯曲齿面的活塞齿部和具有倾斜的平坦齿面的活塞齿部,所述定子设置有具有突出的弯曲齿面的定子齿部和具有倾斜的平坦齿面的定子齿部,所述环形活塞(10)能够被驱动为相对于所述定子轴向移动。通过以上所述技术方案,弯曲齿面的啮合与平坦齿面的啮合相结合,可以保证开始啮合阶段的平稳传动,噪音更小,并且使得随后的啮合阶段可以将轴向移动转化为匀速转动,提供更稳定的扭矩输出。
