Bevel Gear Drive Shaft Assembly | Custom CNC Machined Shaft
This bevel gear drive shaft assembly transfers rotary motion through a 90-degree turn in compact appliance and power-tool drivetrains. The assembly combines a precision-ground stainless shaft — with bearing journals, cross oil holes and a machined flat — carrying a machined bevel gear head and drive lug that engage the mating gear set.
The shaft is turned and ground from ? 304 / 2Cr13 stainless steel? to ? Ø6 h7? 0.02 mm?; the gear head is machined from ? 40Cr / 20CrMnTi? with teeth finished to ? GB 8 ? and then black-oxided for wear resistance. Shaft and gear are assembled and run-in checked as one unit, so the customer installs a verified assembly rather than matching two separate parts.
H2: Key Features - Ground stainless shaft: smooth bearing journals and stable straightness - Integrated bevel gear head and drive lug — no secondary press-fit alignment - Cross-drilled lubrication/locking holes completed in one setup - Black oxide gear surface for initial wear-in protection - Supplied as a run-in checked assembly, ready for installation
H2: Applications Kitchen and personal-care appliances, power tool drivetrains, small geared mechanisms, and OEM motion assemblies.
