Precision Planetary Gearbox Features

• The gear material is made of high-quality alloy steel through surface hardening treatment, and hardened gear surface hobbing is used to enhance the impact resistance of the gear, reduce gear noise, and improve the service life of the gear.
• The finite element analysis of gear strength is carried out by using ANSYS technology. At the same time, the tooth profile and lead are trimmed on the tooth surface to reduce the impact and noise of gear engagement and increase the service life of the gear train.
• The planet carrier and output shaft adopt an integrated structure design. The bearing of the output shaft adopts a large span design to ensure the maximum torsional rigidity and output load force. The one-time processing technology is used to improve the precision and rigidity of the output shaft and the overall planet carrier
• The box body and internal gear are designed and manufactured in an integrated way. The box body is made of high-quality steel. Through the hot forging process, it has higher strength and toughness, which further improves the accuracy and strength of internal gear.
• The connection between the input end and the motor adopts a simple clamp type locking mechanism, and the dynamic balance analysis is carried out. To ensure the power transmission of concentricity and zero backlash at the connection under high input speed.

Installation of  High-Precision planetary gearbox

(1) Wipe the rust inhibitor, grease, etc. on the shaft	(2) Remove the rubber stopper
(3) Rotate the input shaft to align the hole of the fastening screw with the plug hole. At this time, please confirm that the fastening bolt is loose	(4) Insert the shaft into the coupling slowly with the mounting surface of the reducer facing up. Be careful not to hit the coupling. Make sure that the flange face is close to the flange face of the reducer. Tighten the mounting screws to the specified tightening torque
(5) Use a torque wrench, etc., to tighten the coupling fastening screws to the specified tightening torque	(6) Install the upper rubber stop, and the installation is completed
