Nickel chromium molybdenum alloy steel gear is manufactured with carburizing heat treatment for high abrasion resistance and impact toughness and by honing process to increase gear precision and low noise operation.Internal gear bore uses needle roller to obtain higher abrasion resistance and strength.
Description:
(1).The output shaft is made of large size,large span double bearing design,output shaft and planetary arm bracket as a whole.The input shaft is placed directly on the planet arm bracket to ensure that the reducer has high operating accuracy and maximum torsional rigidity.
(2).Shell and the inner ring gear used integrated design,quenching and tempering after the processing of the teeth so that it can achieve high torque,high precision,high wear resistance.Moreover surface nickel-plated anti-rust treatment,so that its corrosion resistance greatly enhanced.
(3).The planetary gear transmission employs full needle roller without retainer to increase the contact surface,which greatly upgrades structural rigidity and service life.
(4).The gear is made of Japanese imported material.After the metal cutting process,the vacuum carburizing heat treatment to 58-62HRC. And then by the hobbing,Get the best tooth shape,tooth direction,to ensure that the gear of high precision and good impact toughness.
(5).Input shaft and sun gear integrated structure,in order to improve the operation accuracy of the reducer.
1.Low Noise:The use of helical gear design,to achieve a smooth,quite operation of the reducer.
2. High Precision:Backlash is 3 arcmin or less,accurate positioning.
3. High Rigidity,High Torque:The output shaft used large size,large span double support bearing design,which improves the rigidity and torque of the reducer.
4. High Efficiency:1-stage up to 95% or more,2-stage up to 92% or more.
5. Maintenance-Free:Low grease wear,can be lifetime lubrication.
6. Sealing Effect is Good:Lubricating grease with high viscosity,not easy to separate the characteristics,ip65 protection class to ensure that no grease leakage.
7. Installation Unrestrained:Can be installed arbitrarily.
8. Wide Applicability:Applicable to any type of servo motor.
9. An organic [integral] whole output axis.
