The cylindrical gear reducer is a type of helical gear reducer, which is different from the hard tooth surface reducer.The main transmission mechanism of the cylindrical gear reducer is: cylindrical gear wheel, sun gear, external ring gear.Cylindrical gear reducer is a widely used reducer. The whole machine has the characteristics of small structure size, large output torque, large reduction ratio, high efficiency, safe and reliable performance.
The number of stages is the number of sets of spur gear gears.Since one set of planetary gears cannot meet the larger transmission ratio, sometimes 2 or 3 sets are needed to meet the requirements of supporting larger transmission ratios. Due to the increase in the number of planetary gears, the length of the 2-stage or 3-stage reducer will be reduced. Increases, efficiency will decrease. Due to structural reasons, the minimum single-stage deceleration is 3, and the maximum is generally not more than 10. Common reduction ratios are: 3, 4, 5, 6, 8, 10. Reducer The number of stages generally does not exceed 3, but some large reduction ratio custom reducers have 4 stages.
