AI Summary AI generated
This standard specifies evaluation items, indicators, and methods for grading the product quality of arc cylindrical worm reducers, applicable to ZC1 single-stage reducers produced per JB/T 7935. Products are classified into qualified, first-class, and superior grades, covering overall machine performance (load capacity, life, efficiency, noise, sealing, temperature rise), production process quality (parts, assembly), and user service. Key indicators include bearing life ≥8000 h, worm stress cycles, efficiency, and noise limits. Sampling follows 20% of batch or single unit, with weighted comprehensive evaluation determining the grade.
本标准规定了圆弧圆柱蜗杆减速器产品质量分等的评定项目、指标与方法，适用于按JB/T 7935生产的ZC1型单级减速器。标准将产品分为合格品、一等品和优等品，涵盖整机性能（如承载能力、寿命、效率、噪声、密封、温升）、生产过程质量（零件、装配）及用户服务。关键指标包括轴承寿命不低于8000小时、蜗杆应力循环数、效率、噪声限值等。抽样方法按批量20%或单件抽取，采用加权综合评定法，总分决定等级。
