Planteary Speed Reducers
Planetary speed reducers, also known as planetary gear reducers, are a type of gear system commonly used to reduce speed and increase torque in various mechanical applications. This type of gear system typically consists of a central "sun" gear, multiple surrounding "planet" gears, and an outer "ring" gear. Planteary Speed Reducers are a type of gear system used in machinery to achieve speed reduction. Planteary Speed Reducers,Planetary gear systems have three main components: a sun gear in the center, planet gears that revolve around the sun gear, and a ring gear that surrounds the planet gears. Planetary speed reducers are preferred in many industrial and mechanical systems due to their compact design, high efficiency, and ability to handle high torque. They are commonly used in industries such as aerospace, automotive, construction, and manufacturing, as well as in applications like conveyor systems, robotics, and wind turbines.
Helical Gear Series:PET
Planteary Speed Reducers， The name planetary gearbox has some resemblance to astronomy. The structure is indeed similar to the solar system - there is a sun gear in the middle, surrounded by several planetary gears, and a large gear ring is placed on the outside. The planetary gear supports the planetary carrier and outputs power. This whole set is squeezed into a small shell, but the energy density is frighteningly high. The first time I disassembled a planetary gearbox was many years ago in the laboratory of TallMan Robotics Limited. The master threw me a disassembled sample and asked me to put it back on my own. The sun gear is small, with three planetary gears evenly distributed around it. The teeth are polished to a shiny finish, and when you turn it with your fingers, the smooth feeling is addictive. After installation, the input shaft rotates many times before the output shaft is willing to move a little bit - that's how the reduction ratio comes about. The benefits of planetary gearboxes can be summarized into three points: small size, large load capacity, and high precision. The gears mesh at several points at the same time, and the force is distributed, so they can naturally carry heavy tasks. The backlash can be made very small, which is particularly crucial for servo motors that require frequent forward and reverse rotation. The guys from TallMan Robotics Limited who make robot joints prefer to use this type of gearbox. Each joint of the robotic arm is fitted with a small space, which not only needs to transmit sufficient torque, but also ensure precise movement and endure long periods of agitation. The planetary gearbox can withstand it. Speaking of which, there are also different levels of this thing. Ordinary cycloidal grinding has careless tooth surface treatment and produces loud noise after prolonged use; Good ones are different, with hard tooth surfaces, stable backlash, and even after running for several years, they look like new. You get what you pay for, in the field of precision transmission, it is always the truth.
