The invention belongs to the technical field of transmission, and particularly relates to a jacking transmission and brake assembly. The jacking transmission and brake assembly comprises a jacking transmission mechanism and a brake mechanism; the jacking transmission mechanism comprises a base frame, a driving wheel, a driven wheel, a linkage shaft, a worm wheel and a worm, the driving wheel is rotationally matched with the base frame and meshes with the driven wheel, the driven wheel and the worm wheel are coaxially mounted through the linkage shaft for linkage, the linkage shaft is rotationally matched with the base frame, the worm wheel is in transmission connection with the worm, and the worm is vertically and fixedly mounted; and the braking mechanism is used for braking reverse transmission of the jacking transmission mechanism under the pressure action of external force. The jacking transmission and brake assembly, the operation of lifting and braking after lifting to the targetposition is achieved; and by adopting transmission fit of the worm wheel and the worm, jacking precision is high.

    本发明属于传动技术领域,具体涉及一种顶升传动及制动总成,包括顶升传动机构和制动机构;所述顶升传动机构包括基架、主动轮、从动轮、联动轴、蜗轮和蜗杆,主动轮转动配合于基架,主动轮与从动轮啮合,从动轮与蜗轮通过联动轴同轴安装以联动,联动轴转动配合于基架,蜗轮与蜗杆传动连接,蜗杆竖直固定安装;所述制动机构,用于对顶升传动机构在外力压力作用下的反向传动进行制动。本发明的顶升传动及制动总成,实现抬升以及抬升至目标位置后制动的操作;而且,采用蜗轮与蜗杆的传动配合,顶升精度高。
