Features and Differences of Various Types of Gearboxes in STEPPERONLINE
Currently, STEPPERONLINE already has many types of gearboxes for sale. To make it easier to choose the right gearbox, this article will introduce the characteristics and differences of various types of gearboxes currently on sale.
EG Series Planetary Gearbox
MG Series Planetary Gearbox
TG Series Planetary Gearbox
Right Angle Planetary Gearbox
Helical Planetary Gearbox
Harmonic Gearbox
Worm Drive Gearbox
EG Series Planetary Gearbox
The EG series planetary gearbox is a standard series of STEPPERONLINE planetary gearboxes. It has the characteristics of high precision and high efficiency and is suitable for most applications.
The backlash of EG series gearboxes is generally <=20 arcmin, the maximum input speed is 3000 rpm, and the protection level is IP54. The input flange size of the EG series gearbox adopts standard NEMA size and is suitable for various motors with standard NEMA installation dimensions.
In addition, it should be noted that some of the EG series gearboxes are specially adapted to short-axis motors, and the series number is EGS. Therefore, when selecting EGS series gearboxes, you need to pay attention to whether they are suitable for the shaft length of the motor.
MG Series Planetary Gearbox
The gears of the MG series planetary gearbox are made of powder metallurgy, which makes it less precise and has a lower input speed than the EG series gearbox. However, the price of the MG series gearbox is lower and the cost performance is higher. Therefore, the MG series gearbox is a good choice in applications that do not require high accuracy.
The backlash of MG series gearboxes is generally <=50 arcmin, the maximum input speed is 1000 rpm, the protection level is IP54, and the input flange size adopts standard NEMA size. Compared with the EG series gearbox, the MG series gearbox is shorter and suitable for applications with limited installation space.
It should be noted that MG series gearboxes are adapted to short-shaft motors. Therefore, when selecting MG series gearboxes, you need to pay attention to whether they are suitable for the shaft length of the motor.
TG Series Planetary Gearbox
TG series planetary gearbox is a gearbox specially developed by STEPPERONLINE for servo motors. Compared with the EG series gearbox, the TG series gearbox has higher precision and is suitable for use with servo motors.
The backlash of the TG series gearbox is generally <=15 arcmin, the maximum input speed is 3000 rpm, the protection level is IP54, the input flange size adopts the standard servo motor size, and is suitable for various standard size servo motors.
Right Angle Planetary Gearbox
The angle between the output shaft and the input shaft of the RYG series right-angle planetary gearbox is a right angle, so they are suitable for applications that require changing the output direction.
The backlash of RYG series gearboxes is generally <=20 arcmin, the maximum input speed is 3000 rpm, and the protection level is IP54. The input flange size of the RYG series gearbox adopts standard NEMA size and is suitable for various motors with standard NEMA installation dimensions.
Helical Planetary Gearbox
The gears inside the helical planetary gearbox are helical gears instead of conventional spur gears, which gives it higher accuracy and stronger load capacity. Compared with the EG series planetary gearbox, the helical planetary gearbox has higher precision and a larger maximum allowable torque. Therefore, helical planetary gearboxes are suitable for applications with high load and accuracy requirements.
The backlash of the helical planetary gearbox is generally <=7 arcmin, the maximum input speed is 3000 rpm, and the protection level is IP65. The input flange size of the helical planetary gearbox is the servo size, which is suitable for servo motors and is not suitable for stepper motors.
Harmonic Gearbox
The harmonic gearbox transmits motion through the metal deformation of the flexspline, which gives it high precision and torque. Harmonic gearboxes are suitable for applications where high precision is required.
The backlash of harmonic gearboxes is generally <=7 arcsec, and the maximum input speed is 3500 rpm. The installation size of the harmonic gearbox does not match the motor, so a mounting flange is required when using the harmonic gearbox.
It should be noted that STEPPERONLINE's harmonic gearbox is not equipped with a mounting flange, and there is currently no mounting flange for sale, so please purchase the mounting flange from other suppliers according to the mounting dimensions of the motor.
Worm Drive Gearbox
The angle between the output shaft and the input shaft of the worm gearbox is a right angle, but they are not on the same plane. Compared with planetary gearboxes, worm gearboxes can withstand larger loads but have worse accuracy, so they are suitable for applications with larger loads and no accuracy requirements.
The backlash of the worm gearbox is generally <=1 degree, and the maximum input speed is 1500 rpm, so it is not suitable for brushless motors and servo motors with higher speeds. STEPPERONLINE's worm gearbox supports a variety of flange specifications and can be adapted to stepper motors or three-phase asynchronous motors with various flanges.
It should be noted that the STEPPERONLINE's worm gearbox does not come with an output shaft, so you need to purchase the output shaft separately when choosing a worm gearbox.
