This helical internal gear housing is customized for planetary gear reducer. It has special housing structure different from normal internal gear with ring structure. Instead of using a separate ring gear pressed or bolted into a housing, this design cuts the helical internal teeth directly into the housing bore. The housing itself becomes the gear. This eliminates assembly tolerances between the ring and the housing, improves concentricity, and allows for a more compact overall package. The special housing structure also handles higher torque loads without risk of the ring gear loosening or shifting under vibration.

Typical Applications of Helical Internal Gear Housing
This integrated gear housing is commonly used in heavy-duty planetary reducers for mobile machinery, such as excavator swing drives, crane hoists, and wheel drives for mining haul trucks. It also suits industrial applications including winch gearboxes, concrete mixer drives, and robotic axis reducers where space is tight but torque demand is high. The direct-to-housing gear design handles shock loads and vibration better than pressed ring solutions, making it a reliable choice for off-road, marine, and wind turbine pitch drives. For applications requiring sealed, compact, and maintenance-friendly reducer layouts, this housing simplifies assembly and improves long-term stability.

Tube Forging
When gears need high performance that needs to withstand high loads, high stress, impact loads or fatigue loads, forgings are suggested to use. Forging allows metal fibers to be continuously distributed along the gear profile, significantly improving root strength and fatigue life.
Turning
This is the process of cutting and shaping solid materials into precise parts. It uses tools like lathes, mills, and drills to remove excess material. Machining transforms a simple block of metal into a finished, functional component.
Internal Gear Shapping
Gear shaping is a gear cutting process that used cutting tool that is essentially a “master gear” reciprocates while meshing in a synchronized rolling motion with the gear blank.The cutter is usually moving up and down.
Heat Treatment
Gears need to be running with two gears or above two gears, that makes them easy to be worn-out. That’s why most types of gears need to be harden through heat treatment.
Ring Gear Grinding
Gear Grinding is the the most common high-precision method for finishing hardened gears under gleason profile. There are two methods to use an abrasive grinding wheel removes material from the tooth flanks.
