JB/T 7000-2010 (English Version) PDF

Scope: This standard specifies the type, size, basic parameters and technical requirements of TZL, TLS, TZLD, TZSD, TZLDF, TZSDF and combined series coaxial cylindrical gear reducers (hereinafter referred to as reducers). This standard applies to metallurgy, mining, energy, building materials, chemical industry and other industries. This standard reducer is suitable for horizontal and vertical installation, and the input speed is not greater than 1500 r/min. This standard reducer is suitable for ambient temperatures of -40°C to 40°C. When it is lower than -10°C, the lubricating oil should be preheated to above 0°C before starting.
