The gear wear of the elevator traction machine results in operating noise exceeding 65dB and vibration values exceeding the standard, affecting ride comfort. Traditional maintenance requires a 72 hour shutdown. Daokedao adopts a night time rapid repair plan, using 40CrNiMoA alloy powder, with a tooth surface cladding layer thickness of 0.1mm and a hardness of HRC55-58. The tooth profile accuracy is restored to level 7 standard, and the operating noise is reduced to below 55dB, with a vibration value of ≤ 0.1m/s ². The repair of the Φ 80mm gear only takes 8 hours (during nighttime downtime), with a cost of 5000 yuan, saving 15000 yuan compared to new gears, and a lifespan of 90% of new parts. After being applied by a certain property management company, the elevator failure rate has decreased from 20% to 1%, and the resident complaint rate has decreased by 95%, avoiding compensation losses caused by long-term downtime. It is compatible with traction machine gears such as passenger elevators and freight elevators, and has served more than 50 property management companies with a customer satisfaction rate of 98%.
