Description

Flexible transmission structure of ring cooler Technical Field The invention relates to a flexible transmission structure of a ring cooler. Background The ring cooler is a key device for cooling high-temperature sintered ores in a sintering process, and the stability of a transmission structure of the ring cooler directly influences the cooling efficiency and the service life of the device. The traditional annular cooler mostly adopts friction wheel transmission or rigid gear transmission, and has the obvious defects that the friction wheel transmission is easy to cause driving failure due to slipping, a monitoring device is additionally arranged, the maintenance cost is increased, the rigid gear transmission is easy to cause stress concentration due to installation errors or thermal deformation, the abrasion of parts is accelerated, and the rigid gear transmission is difficult to adapt to the heavy-load working condition of the large-scale annular cooler. In addition, the rigidity of the transmission structure is insufficient, so that the sealing failure of the trolley is aggravated, cold air leakage is caused, the cooling efficiency is reduced, and the energy consumption is increased. In recent years, some improvements have attempted to alleviate the above problems by flexible techniques. For example, a multi-point engagement flexible drive reduces dynamic load impact through power splitting and cushioning devices, but is complex in structure and high in manufacturing cost, and flexible suitability of the drive system is not fully studied. Therefore, there is a need to develop a flexible transmission structure with high transmission precision, strong load adaptability and low maintenance cost, so as to solve the bottleneck problems of the conventional transmission method in reliability, energy efficiency and large-scale application.
