摘　　要：针对空调产品中使用新工艺生产的低成本旋压带轮,文中介绍了皮带轮关键尺寸公差设计的评估和分析计算方法,使原铸造带轮在被旋压带轮替换后,能够满足正确的传动比,从而使风机系统能够提供正确的风量,并且保证马达功率不会上升,确保空调系统的能效比不会因此下降。Aiming at the low-cost spinning pulleys produced in the air-conditioning products using the new technology, thepaper introduces the evaluation and analysis method of the key dimensions tolerance design for the pulleys. By using thiscalculation method, the spinning pulley can realize proper transmission ratio and air volume after substituting for the originalcasting pulleys, and can ensure that the motor power will not rise, the air conditioning system energy efficiency ratio will notbe reduced.
