What are the structural characteristics and working principles of the SBD50, SBD65, and SBD75 reducers used by Shenke

The structural characteristics and working principle of the SBD50 SBD65 SBD75 reducer used by Shenke are as follows:

SBD structural characteristics:

Planetary cycloidal reduction transmission: As a front stage reduction, it has the advantages of high transmission efficiency, compact structure, small volume, and light weight. The planetary cycloidal reduction mechanism adopts bearing steel (Gcr15) that has been quenched and treated, with a hardness of HRC58-62, which improves the wear resistance and service life of the gears.

Spiral bevel gear reduction transmission: As a rear stage reduction, it has the advantages of smooth transmission, low noise, and high load-bearing capacity. The spiral bevel teeth are made of high-quality carburizing steel (20CrMoTi), and after carburizing and quenching treatment, the hardness also reaches HRC58-62, further improving the performance and reliability of the reducer.
Direct combination: The planetary cycloid reduction transmission and the bevel gear reduction transmission are directly combined, reducing intermediate transmission links and improving transmission efficiency and reliability. At the same time, the use of shaft hole output enables the model to achieve the smallest possible size, making it easy to install and use.

Working principle of SBD:

Power input: The power of the motor is transmitted to the planetary cycloidal reduction mechanism through the input shaft of the gearbox.
Planetary cycloidal reduction: The planetary cycloidal reduction mechanism converts the high-speed rotational motion of the input shaft into low-speed rotational motion through the meshing transmission between the planetary gear and the cycloidal gear, and transmits it to the bevel gear reduction mechanism.
Spiral bevel gear reduction: The spiral bevel gear reduction mechanism further reduces the speed and transmits power to the output shaft of the reducer through the meshing transmission between the spiral bevel gears.
Output power: The output shaft of the reducer transmits the power after deceleration to the working equipment, driving it to operate.
