Large straight bevel gears transmit power between intersecting shafts through straight-cut teeth on large-diameter conical blanks. As the driving gear rotates, its massive teeth engage progressively with the mating gear’s teeth, creating rolling and sliding contact that efficiently transfers high torque loads, typically at 90-degree angles.

Large Straight Bevel Gear Typical Applications
Large straight bevel gears are essential components in heavy industrial applications where dependable right-angle power transmission under high torque and severe operating conditions is required. Common applications include:
- Large industrial gear drives and speed reducers
- Steel mill rolling machinery
- Oil and gas industry pumping units
- Cement and aggregate processing machinery
- Marine main propulsion systems for vessels
- Power generation equipment including hydroelectric turbines
- Bulk material handling systems for ports and terminals
Their exceptional strength, durability under extreme loads, and proven reliability in harsh environments make large straight bevel gears indispensable for heavy-duty power transmission applications where failure is not an option.

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.
Gear Planing
Gear planing is a cutting process that uses reciprocating motion to generate precise gear teeth profiles.
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.
ID & OD Grinding
ID grinding, OD grinding, Surface grinding are all belonging to CNC grinding which are the foundational precision abrasive machining processes used to achieve exceptional dimensional accuracy and surface finishes, especially on hardened materials.
CNC Machining
CNC machining is a an automated manufacturing process controlled by pre-programmed computer software and code. Normally gears are designed in CAD software. CAM software translates the CAD model into G-Code, a machine language that dictates tools paths, speeds, feeds, and all movements.
Marking
Precision laser marking permanently engraves traceability data (part numbers, date codes, logos) onto gears, ensuring reliable identification and quality tracking throughout the product lifecycle.
Clean & Package
Before shipment, every gear is carefully cleaned, dried, and rust-protected – ensuring they arrive in optimal condition, ready for immediate installation.
