Product type and characteristics: The steel rope traction belt conveyor drive adopts NGW type
non-standard planetary single speed double reduction gearbox, which has the characteristics of small size, light weight,
stable operation, high efficiency and low noise. This type of planetary single speed double reduction gearbox uses a sun
gear to float. When the single speed double reduction gearbox is working, the body, the casing, the internal gear, etc. are
fixed. The torque is input from the high speed shaft, decelerated by the internal gear, and
finally output to the steel rope traction belt conveyor by the low speed shaft.
NGW type non-standard planetary single speed double reduction gearbox specific models: K136P, K137P, K143P, K144P,
K147P, K150P, K240P, K241P, K242P, K247P Product type and characteristics: The steel rope
traction belt conveyor drive adopts NGW type non-standard planetary single speed double reduction gearbox, which has
haracteristics of small size, light weight, stable operation, high efficiency and low noise. This
type of planetary single speed double reduction gearbox uses a sun gear to float. When the single speed double reduction gearbox is working, the body,
the casing, the internal gear, etc. are fixed. The torque is input from the high speed shaft,
decelerated by the internal gear, and finally output to the steel rope traction belt conveyor by
the low speed shaft.

Working conditions: 1. The maximum speed of the input shaft is not more than 1500r/min; 2. The working environment temperature of the single speed double reduction gearbox is -40 to +45 °C. If the working
environment temperature is lower than 0 °C, the lubricating oil should be heated to above 0 °C
before starting the equipment. 3. The single speed double reduction gearbox can work in both directions.
Structure type and working principle: It can be seen from the structural diagram that the torque of the motor is input from the high-
speed shaft, and is transmitted to the high-speed sun gear via the floating tooth sleeve. The
sun gear meshes with the planetary gear, and the planetary gear meshes with the inner ring
gear at the same time. Since the inner ring gear is fixed to the body, The planetary wheel
produces a combined motion that rotates both about its own axis and about the axis of the sun
gear. At this time, the torque transmitted to the planetary gear is transmitted to the planetary
shaft due to its revolution, and then the planetary shaft transmits the torque to the planet
carrier fixedly coupled thereto, and then transmits the torque to the inner gear plate and the
floating tooth sleeve. Low speed sun gear. Low-speed torque transmission from the sun gear
to the low-speed shaft is the same as the high-speed stage.
