Requirements of the national standard for reduction gearbox design
Recommendation: go to the standard museum to check it.1, JB / T 9050.1 "general technical specification for cylindrical gear reducer";2, JB / T 8905.2 "pedestal type reducer for crane";3, JB / T 8853 "cylindrical gear reducer";4, YB / T 050 "YNK gear reducer for metallurgical equipment";There are many, not one by one, the standard library has inquiry service, free of charge.
I wonder what kind of gear reducer you're talking about. In the future, for specific products, the country has not formulated specific standards, even if there are standards, but also the old standards, for reference only, to encourage enterprises to set standards for their products.
There are different standards for different types of speed reducers. For example, ZDY, ZLY and ZSY, hardened surface cylindrical gear reducer standard for JB/T8853-2001; DBY and DCY series bevel gear reducer standards for JB/T9002-1999, etc..
