15 2026-07 Today, Guangming Group shares the core structure and specifications of D-bore helical gears.
It is formed by milling one flat side of a round hole, which locks the flat section of the transmission shaft without flat keys to prevent slipping.
Structure: Circular wall with one flat positioning edge
Matching method: Interference press-fit as the primary assembly method; heavy-load versions feature threaded set screw holes on the hub for secondary locking reinforcement.
Hub: Thickened cylindrical hub improves the torsional strength of the D-bore and avoids cracking of the bore wall under torque.
As a professional manufacturer and factory based in China, we strictly control the dimensional tolerance of each D-bore to guarantee stable fit performance for global buyers and suppliers.

Mechanical method: including solid crushing and liquid crushing. Solid crushing is the process of rolling or vibrating a cylinder to impact and crush materials into powder using steel balls, suitable for brittle metals and alloys; Liquid pulverization is mainly the atomization method, which disperses molten metal into mist like droplets through high-pressure gas, liquid, or high-speed rotating blades. After cooling, it becomes powder and is suitable for metals with low melting points
