In the industrial transmission field, planetary gear reducers have become key components in automation equipment, construction machinery, and new energy equipment, thanks to their compact structure, large transmission ratio, and high load-bearing capacity. We selected the fancy ATG planetary gear reducer and will take you to understand its real advantages through internal structure via full-process disassembly.
The ATG reducer feels solid in hand. Its body adopts an integrated die-cast aluminum alloy housing with an oxidized surface, offering a smooth touch without scratches. Opening the casing reveals the core planetary gear transmission mechanism: consisting of a sun gear, three planet gears, an internal gear ring, and a planet carrier.
The sun gear and input shaft are an integrated forged structure instead of welded, fundamentally enhancing power transmission stability and avoiding fracture risks. Both the sun gear and planet gears use 20CrMnTi with carburizing, quenching, and gear grinding processes, reaching a hardness of HRC58-62. Multi-tooth meshing distributes load, allowing the high-hardness tooth surface to withstand greater loads, while precise tooth pitch ensures meshing accuracy with planet gears and reduces transmission loss. The integrated dual-support planet carrier with large-span bearing distribution ensures torsional rigidity, reduces redundant parts, and lowers manufacturing costs.
A deep disassembly speaks louder than a thousand promotional words. The value of a high-quality planetary gear reducer lies not only in the impressive numbers on the parameter sheet but also in every gear chamfer, every precision seal groove, and every heat treatment process. It is an industrial product integrating materials science, mechanical engineering, and manufacturing art, serving as a reliable cornerstone for the stable, precise, and efficient operation of your equipment.
