Transmission device for rotary frame of circular cooler

The invention discloses an annular cooler rotation frame transmission device which comprises a plurality of spliced transmission module units and transmission wheels in transmission connection with the transmission module units. Each transmission module unit comprises a connecting support fixedly connected to the periphery of the rotary frame and a plurality of transmission assemblies arranged on the connecting support in the circumferential direction, every two adjacent transmission assemblies form a tooth groove, and the transmission wheels are meshed with the transmission assemblies so as to be in transmission connection with the connecting supports. According to the transmission device for the rotary frame of the circular cooler, the multiple spliced transmission module units form a whole, modular combination is formed, the transmission assembly is installed on the connecting support before installation, part assembling and debugging do not need to be carried out on site, all the module units are directly
