JB/T 6950-1993 Planetary cone disc continuously variable transmission

This standard specifies the type, basic parameters, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of planetary cone-disc continuously variable transmissions. This standard applies to transmissions with a speed ratio range of 4 to 8 and a power transmission of 0.09 to 22 kW. The operating ambient temperature of the transmission is -20 to 40°C. When the ambient temperature is below 0°C, the lubricating oil should be preheated before starting.

When the transmission is basically constant power (referred to as constant power), it is represented by "G\", and when it is basically constant torque (referred to as constant torque), there is no code. 3.1.5 Number of poles of the motor
The number of poles of the motor is expressed mathematically. There is no code for a four-pole motor. 3.2 Marking example
The frame number is 075, equipped with a four-pole motor with a power of 7.5kW, and a constant power planetary cone disk continuously variable transmission with an assembly type code of 1A. The mark is:
