Slewing mechanism, chassis assembly and engineering machine
The invention provides a slewing mechanism, a chassis assembly and an engineering machine, and relates to the technical field of slewing bearings. The slewing mechanism comprises a rotation driving assembly, a first meshing piece and a second meshing piece; the rotation driving assembly comprises a first driving shaft and a second driving shaft which are connected in a sleeved manner, and the first driving shaft and the second driving shaft are in clearance fit in the radial direction of the first driving shaft; the first driving shaft and the second driving shaft are relatively fixed in the circumferential direction of the first driving shaft; and the rotation driving assembly further comprises a rotation driving piece, the first driving shaft is connected with the rotation driving piece,the second driving shaft is connected with the first meshing piece, and the first meshing piece meshes with the second meshing piece. According to the slewing mechanism, the technical problem that inthe working process of the engineering machine, as the gravity centers of an upper chassis and a lower chassis change continuously, the upper chassis and the lower chassis incline relatively, then bending pressure is exerted on the part between a gear in a slewing bearing and an output shaft of a motor, and consequently the output shaft of the motor deforms or breaks is solved.
本发明提供一种回转机构、底盘总成和工程机械，涉及回转支承技术领域。该回转机构包括旋转驱动组件、第一啮合件和第二啮合件；旋转驱动组件包括相互套接的第一驱动轴和第二驱动轴，沿第一驱动轴的径向，第一驱动轴和第二驱动轴之间间隙配合；沿第一驱动轴的周向，第一驱动轴和第二驱动轴之间相对固定；旋转驱动组件还包括旋转驱动件，第一驱动轴与旋转驱动件连接，第二驱动轴与第一啮合件连接，第一啮合件与第二啮合件啮合。本发明缓解了在工程机械工作过程中，上底盘和下底盘的重心会不断变化，导致上底盘和下底盘之间相对倾斜，进而会使回转支承中的齿轮与电机的输出轴之间受到弯曲压力，使电机的输出轴产生变形或折断的技术问题。
