Sell Yengood Planetary Gearbox Reducer with Start Gear Three-Stage Speed Reducer Ratio 1:20 nice shopping best price

Description: The product will be upgraded constantly, the appearance and color may be changed, please don't mind. And take a consideration before place the order if you have request for color or appearance. There are several small steel columns for the connection between the output shaft and the gear box. When we rotate the output shaft, these small steel columns will be displaced, and the output shaft will be blocked and cannot be rotated. The output shaft is very smooth. The forward and reverse rotations are equally smooth. We do not know the technology of mechanical transmission. We just guess their role is to prevent the output shaft from driving the gear box in turn. Gearbox reduction ratio: about 1: 20 The gearbox is divided into three stages of planetary reduction, the second stage is plastic gears, and the first stage is metal gears. The outer wall of the planetary gearbox is thick alloy metal. The strength should be good, but this gearbox can be fixed without screw holes. Is based on the position, please buyers to observe carefully before buying Package includes: 1 piece of planetary reducer
