JB/T 7000-1993 Coaxial cylindrical gear reducer

This standard specifies the type, size, basic parameters and technical requirements of TZL, TZS, TZLD and TZSD series coaxial cylindrical gear reducers. This standard applies to metallurgy, mining, energy, building materials, chemical industry and other industries. The peripheral speed of the reducer gear is not greater than 20 m/s, and forward and reverse rotation are allowed. The reducer is suitable for horizontal installation, and the output shaft is allowed to be installed tilted downward. The angle between the output shaft and the horizontal plane is not greater than 20°. The working environment temperature of the reducer is: -40~40℃. When it is lower than 0℃, the lubricating oil should be preheated before starting. TZLD and TZSD type reducer direct-coupled motors are Y series three-phase asynchronous four-pole motors. The working altitude of TZLD and TZSD type reducers: no more than 1000m. JB/T 7000-1993 Coaxial cylindrical gear reducer JB/T7000-1993 Standard download and decompression password: www.bzxz.net

This standard stipulates Type, size, basic parameters and technical requirements of TZI.TZS.TZL), TZSI) series coaxial cylindrical gear reducers (hereinafter referred to as reducers).
This standard is applicable to reducer gears in industries such as metallurgy, mining, energy, building materials, chemicals, etc. The peripheral speed of the gear is not greater than 20m/s, and forward and reverse rotation are allowed. The reducer is suitable for horizontal installation, and the output shaft is allowed to be installed downwards and tilted. The angle between the output shaft and the horizontal plane is not greater than 20°. The operating ambient temperature of the reducer is: -40~·40C, lower than 0 (the lubricating oil should be preheated before starting: TZL.D, TZSD) type reducer direct-connected motor is a Y series three-phase asynchronous four-pole motor. The operating altitude of TZ1.D.TZSD type reducer: no more than 1000m. 2 Reference standards
