JB/T 5559-1991 Cone envelope cylindrical worm reducer

This standard specifies the basic parameters, types, dimensions and markings, technical requirements, load-bearing capacity and selection methods of single-stage conical envelope cylindrical worm reducers. This standard reducer is mainly suitable for metallurgy, mining, lifting, transportation, chemical industry, construction and light industry. The speed of the reducer worm shall not exceed 1500r/min. The working environment temperature of the reducer is -40~40℃. When the working environment temperature is lower than 0℃, the lubricating oil must be heated to above 0℃ before starting or a lubricating oil with a low freezing point should be used. The reducer worm shaft can run in both forward and reverse directions. JB/T 5559-1991 Conical envelope cylindrical worm reducer JB/T5559-1991 Standard download decompression password: www.bzxz.net

Subject content and scope of application
JB/T 5559.-. 91
This standard stipulates The basic parameter type, size and marking, technical requirements, load-bearing capacity and selection method of Guangzhou's single-stage cone-enveloped cylindrical worm reducer (hereinafter referred to as the reducer). This standard reducer is mainly suitable for industries such as metallurgy, mining, lifting, transportation, chemical industry, construction and light industry. The speed of the reducer worm does not exceed 1500r/min. The working environment temperature of the reducer is 40°C + 40°C. When the working environment temperature is lower than 0(°C, the lubricating oil must be heated to () or above or use low freezing point lubricating oil before starting. The worm shaft of the reducer runs in both forward and reverse directions. 2 Reference standards
