    Gearbox Buying Guide

    Gearbox is an important part widely used in the rotation of the system. It consists of two or more gears, including at least one drive gear with a certain diameter, and one smaller gear connected to the drive mechanism (electric motor, wind turbine, diesel generator, and so on).

    What is a Speed Reducer?

    Speed reducers primarily serve two purposes. First, they can multiply the torque generated by the input power source to increase the amount of usable work. Second, they are used to reduce the input power source speed to achieve desired output speeds. For this reason, a smaller, less expensive motor with a speed reducer may enjoy wider application fields than a larger motor without one.


    Planetary Speed Reducer VS Gear Speed Reducer

    Planetary speed reducer is a kind of deceleration equipment with a wide range of uses. The precision of planetary reducer is very high. Under the premise of ensuring precise transmission, planetary reducer is mainly used to reduce speed, increase torque and reduce the load/motor moment of inertia ratio. Planetary reducer is also called servo reducer or servo planetary reducer. The gear reducer is an externally meshing involute helical cylindrical gear reducer produced according to the national professional standard ZBJ19004. This article compares the similarities and differences between two speed reducers in general, characteristics and application approaches.

    When does a Servo Motor Combine with a Gear Reducer?

    In modern industrial equipment, particularly when using in the high precision conditions, the servo motor technology is developed into high torque density, as a result, the rotation speed may be up to more than 3000 rpm. With the improvement of rotation speed, power density of servo motor is also greatly improved, that means whether a servo motor needs to be matched with a reducer gearbox is mainly determined by the application need and the cost. In following application conditions, a servo planetary reducer gearbox is needed.

    Planetary Speed Reducer Installation Guide

    The correct installation, use and maintenance of the planetary speed reducer & gearbox are important parts of guaranteeing the normal operation of the machine and equipment. How to install the motor to the planetary gearbox properly? Here are some tips for your reference.

    Planetary Speed Reducer Gearbox Selection Guide

    In the family of gearboxes, the planetary speed reducer or gearbox is widely used in transmission systems such as servo motors, stepper motors and DC motors due to its small size, high efficiency, wide deceleration range and high precision. In the premise of ensuring the precision transmission, it is mainly used to reduce the speed, increase torque and reduce the inertia ratio of the loads or motors. Thus, how to choose a right planetary speed reducer or gearbox to fit a motor?

    Planetary Speed Reducer Working Principle and Applications

    The planetary speed reducer or gearbox is a kind of transmission mechanism. It utilizes the speed transducer of the gearbox to reduce the turnover number of the motor to the required one and obtain a big torque. How does a planetary gearbox work? We can learn more about it from the structure. The main transmission structure of the planetary gearbox is planet gears, sun gear and ring gear.
