4.1.2 The power supply voltage of the motor should be stable and stable.The gear surface point density limit is calculated by the formula in T/T9 (SI).3. 6 Verification specifications
6.1 Factory inspection
Products shall be inspected and tested before leaving the factory
"delivery inspection control" requirements are implemented, and shall comply with the requirements of Article 4. 6.2 Random inspection
6.2.1 The following situations require random inspection: a) For various machine models with an annual production of more than 100 units, random inspection shall be carried out at least once a year. If the annual production is less than 153 units, random inspection shall be carried out within the period when the cumulative production reaches 100 units. b) When evaluating or approving the quality of fat products.
Center) If two major technical performances fail to meet the standards, the sample inspection shall be reduced by 10 units. When the batch is less than 10 units, one unit shall be inspected. If the sample inspection fails, additional screening shall be conducted. The unqualified units shall be excluded from the inspection. 6.2.3 The items of sample inspection shall be verified according to the requirements of 5.1.5.2.5.4, so that the acceptance of 5.1, 5.33 is allowed. .4 requirements! 6.3 Type inspection according to the following requirements: a. Finalization of new products, when the product design, process or material has major changes that are enough to cause changes in characteristics and parameters, and when the new product is put into production, it will be stopped for more than 5 years. When there are special requirements for the product:
6.3.2 Frequent inspection according to 5. 3 Implementation.
Marking, packaging, transportation, purchase and storage
7.1 Each reducer shall be equipped with a product nameplate according to the position specified on the product drawing. The nameplate shall be separated from the base by a ruler when installed. The inner width of the product nameplate is as follows:

7.2 The surface of the reducer shaft extension and the chain should be cleaned of rust and oil film. They should be tightly packed with plastic wrap, or other protective measures should be used: the exposed surface should also be protected from chain.
7.3 The technical documents provided with the returned product include: a) product qualification evaluation and packing list,
b) product instructions. The technical documents should be placed in the plastic and fixed on the inner wall of the box. 7.4 When the product is packed and shipped, it should be fixed in the box to ensure that it is suitable for land and water transportation. 7.5 The outer wall of the packaging should be marked with English words, and the words should be clear and neat to ensure that they are not blurred by water. The content includes: a) the receiving unit and address. b) the product manufacturer's product name and plastic number. d) the outer dimensions of the box. 7.6 During transportation and lifting, the box should be placed upright and not allowed to be wet. The reducer should be clean and prevented from snow and water. 7.7
