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.

Guangming Group Today Talks about Powder Metallurgy of Water Tank Flanges

Powder metallurgy water tank flange is a water tank connection flange formed by metal powder pressing and high-temperature sintering. It belongs to the near net forming process and does not require a large amount of turning and milling processing. It integrates the flange surface, bolt holes, center through holes, and step positioning structure. It is mainly used for small atmospheric water tanks, equipment circulating water tanks, filling machine supporting cooling water tanks, and water pump inlet and outlet flanges.
