Model: Jkongmotor 42mm Round Head Planetary Gearbox Reducer for 42BLS Brushless dc Motor
Planetary gear reducers are compact components that strive to maximize the transmission of torque in various applications. The mechanisms ensure the transmission of high torque levels while simultaneously decreasing the required number of motor revolutions for a set level of power.
Generally, planetary gears are used as speed reducers. They are used to slow down motors and increase the torque. Torque is the working power of the machine.
A planetary gearhead takes a high-speed, low-torque input, say from an electric motor, then increases torque and reduces speed at the output by the gearhead ratio. This lets motors run at higher, more-efficient rpms in equipment that operates at low speeds.
It also enables high torque transmission in a small construction space thanks to the use of multiple parallel tooth combinations with several orbiting wheels. As the torque is distributed over several gear wheels, the tooth forces are smaller than in other types of gear.
A gear reducer is a mechanical transmission device that connects a motor to a driven load. It is also known as a gearbox. It allows you to modify the torque and speed between a motor and a load. Reduction gear assemblies are made up of series of gears.
High efficiency due to low rolling power. Almost unlimited transmission ratio options due to combination of several planet stages. Suitable as planetary switching gear due to fixing this or that part of the gearbox. Possibility of use as overriding gearbox.
