- Scope
- This standard specifies the basic parameters, models, markings, dimensions, technical requirements and load-bearing capacity of vertical cone-enveloping cylindrical worm reducers. The reducers specified in this standard are mainly suitable for chemical, pharmaceutical, construction, food, light industry and other industries. The working environment temperature of the reducer is -15~+40℃, and the altitude does not exceed 1000m. When the working environment temperature is lower than 0°C, the lubricating oil must be heated to above 0°C before starting, or lubricating oil with a low freezing point must be used. The reducer can operate in both forward and reverse directions.
