Helical gears are round metal disks with teeth cut around the circumference. In order for the gear to qualify as a gear, the tooth must be cut so that they run perpendicular to the gear's face. Helical gears are the simplest design of gear produced. They are usually used for the transmission of rotary force. For example, if two shafts are parallel to one another, and one is spinning, a helical gear can help to transfer that force onto the other shaft. Helical gears usually have an operating efficiency of 98% to 99%.

- OEM service offered - Superior quality at competitive price -Customized
We can offer OEM Service for Gear Steel Castings, and those steel castings can be produced in the following conditions:
Heat treatment: Normalized, Normalized and Tempered, Quenched and Tempered
Non-Destructive Testing: Magnetic Particle Testing, Ultrasonic Testing, Penetrant Testing
Material: Carbon Steel, Alloy Steel, meet ASTM, BS, DIN, NF, JIS, ISO standard
Individual Weight: 500KG - 140MT
The Process As Follow: ingot → heat → forging → heat treatment(normalizing+tempering) → inspection → rough machining → UT → 2nd heat treatment → finishing machining → inspection . Quality Control: UT,MT,RT,PT,chemical composition test,mechanical property test,etc. Heat Treatment: Normalize,Quenching,Tempering,Anealled. Surface Treatment: painting,plating,polishing,black oxide,transparent anti-rust oil. Inspection: Besides our in-house inspecion, you could also choose a third party inspection. Standard: ANSI,ASTM,ASME,API,JIS,DIN,BS,EN,KS,UNI,SABS,GOST. Certificate: 1, Raw material certificate(material chemical compositon) 2, Heat treatment sheet report 3, Dimension inspection report 4, UT test report Packing: Seaworthy plywood packaged on stell pallets or as customer's request Delivery Date: Decided by the amount and dimensions of products. Usually we control the large diameter rings' delivery time within 5 weeks after we receive your formal order. Competitive Advantage: Quality control and management to the whole produce process, including ingot smelting,forging, heat treatment, machining and strictly final inspection prior to delivery.
