Product Overview<\/h2>\n
\n
\n \"Alloy\n <\/div>\n
\n

Alloy steel worm and worm gear for auto parts<\/strong> are precision miniature worm gear pairs produced specifically for automotive and high-precision applications \u2014 diameter \u03a65 mm to \u03a6120 mm, module M0.2 to M2.2, in alloy steel, stainless steel, aluminium, copper, brass, iron, titanium, and other materials as required. Manufactured by CNC turning, milling, drilling, hobbing, polishing, and surface treatment with tolerances from 0.001 mm to 0.1 mm. ODM\/OEM accepted. Sample available. Delivery by DHL, TNT, FedEx, or UPS.<\/p>\n

Korea Ever-Power’s alloy steel worm and worm gear for auto parts<\/a> are produced by a factory with more than ten years of experience and hundreds of qualified personnel \u2014 one of China’s leading manufacturers of automotive precision worm gears. High precision machining, cost-effective engineering design, short lead time (sample: 7\u201310 days typical), and high quality with diversification of material and surface treatment options are the defining characteristics of this product line.<\/p>\n<\/p><\/div>\n<\/div>\n

The automotive worm gear pair operates in demanding conditions: repeated load cycling in automotive comfort actuators (window, seat, mirror) means the worm thread and worm wheel tooth must resist contact fatigue over millions of cycles; corrosive environments (humidity, salt, automotive fluids) attack the gear surface; and tight space constraints require the worm gear pair to be as compact as possible at the given module and ratio. Korea Ever-Power’s alloy steel worm and worm gear for auto parts are designed to address all three requirements simultaneously \u2014 through material selection, surface hardening, and precision machining to the tight tolerances that automotive OEM and Tier 1 suppliers require.<\/p>\n

Product Features<\/h2>\n

\"Cylindrical<\/p>\n

\n
\n

High Precision Machining<\/h3>\n

Korea Ever-Power’s alloy steel worm and worm gear for auto parts are machined on CNC hobbing machines, CNC lathes, and CNC milling centres to tolerances from 0.001 mm (precision grade applications) to 0.1 mm (standard industrial applications). The tight tolerance capability \u2014 particularly the 0.001 mm achievable on bore diameter and the thread profile accuracy maintained by CNC hobbing \u2014 is essential for automotive worm gears where the gear pair must assemble correctly in mass production without selective fitting or individual adjustment.<\/p>\n<\/p><\/div>\n

\n

Broad Application Range<\/h3>\n

Automotive, medical, industrial, military, aircraft, and mechanical applications \u2014 Korea Ever-Power’s alloy steel worm gear for auto parts covers the full spectrum of precision worm gear applications. The M0.2 module lower limit (\u03a65 mm minimum OD) reaches the smallest commercially useful worm gear sizes for miniature automotive and medical actuators; the M2.2 module upper limit (\u03a6120 mm maximum OD) covers medium-duty industrial and aircraft actuator sizes. A single supplier for worm gears across all these applications simplifies supplier qualification management.<\/p>\n<\/p><\/div>\n

\n

Cost-Effective Engineering Design<\/h3>\n

More than ten years of experience in automotive precision worm gear manufacture allows Korea Ever-Power to propose cost-effective designs for custom applications \u2014 selecting the minimum module that achieves the required torque capacity, the most economical material that meets the life and environment requirements, and the simplest surface treatment that provides the required corrosion protection. Cost-effective engineering design reduces total cost without compromising the gear set’s performance or service life.<\/p>\n<\/p><\/div>\n

\n

OEM\/ODM Service<\/h3>\n

Korea Ever-Power’s factory + trade business model combines in-house manufacturing capability (CNC turning, hobbing, milling, heat treatment, surface treatment) with direct international sales \u2014 giving automotive OEM and Tier 1 customers factory-direct pricing without the minimum order quantities typical of Chinese gear manufacturers. For customers without drawings, Korea Ever-Power’s engineering team produces a 3D CAD model and drawing from a sample or dimensional sketch, both for customer approval before production.<\/p>\n<\/p><\/div>\n

\n

High Quality and Short Lead Time<\/h3>\n

Sample production in 7\u201310 days is achievable for the majority of alloy steel worm gear configurations in Korea Ever-Power’s standard module range (M0.2\u2013M2.2, \u03a65\u2013\u03a6120 mm). This short sample lead time is made possible by Korea Ever-Power’s large in-house stock of worm gear blanks, tooling, and fixtures in all standard module sizes \u2014 allowing rapid set-up without long procurement lead times for specialised tooling.<\/p>\n<\/p><\/div>\n

\n

Material Diversification<\/h3>\n

Alloy steel, stainless steel, aluminium, copper, brass, iron, and titanium \u2014 Korea Ever-Power’s alloy steel worm gear for auto parts is available in any material the automotive or special application requires. For automotive worm gears where weight reduction is a programme target, aluminium worm wheels (paired with steel worms) reduce rotating mass. For aerospace worm gears where strength-to-weight ratio is critical, titanium alloy worm gears are available. Surface treatment by anodising, galvanising, powder coating, or polishing to match the application environment.<\/p>\n<\/p><\/div>\n<\/div>\n

<\/p>\n

Alloy Steel Worm Gear in Automotive Actuator Drives<\/h2>\n

\"Ever-Power<\/p>\n

Automotive worm gears operate in some of the most demanding conditions in the worm gear family \u2014 miniature size (M0.2\u2013M1.0), millions of load cycles over a 15-year vehicle life, exposure to automotive fluids and humidity, and the requirement for virtually silent operation in the passenger compartment. The following characteristics are critical for automotive worm gear specification:<\/p>\n

\n
\n

Contact Fatigue Life<\/h3>\n

Automotive comfort actuators (window lifters, seat adjusters, mirror fold) cycle 50,000\u2013300,000 times over a 15-year vehicle life. The worm thread and worm wheel tooth must resist pitting fatigue at the contact stress produced by each actuation load. Alloy steel worms (20CrMo, 20CrMnTi) case-carburised to HRC 58\u201362 achieve the Hertzian contact fatigue life required for these cycle counts \u2014 hardened steel provides the fatigue-resistant surface that carbon steel or plastic worm gears cannot match at the same module.<\/p>\n<\/p><\/div>\n

\n

Miniature Module Accuracy<\/h3>\n

At M0.2\u2013M0.5, the worm thread pitch is so small (pitch = \u03c0 \u00d7 module = 0.628\u20131.571 mm) that gear noise and transmission error become highly sensitive to tooth form errors. Korea Ever-Power’s CNC hobbing process at these small modules achieves pitch errors of 2\u20135 \u00b5m \u2014 the accuracy level required to produce quiet, smooth automotive worm gear operation at the motor speeds typical of 12V DC automotive comfort actuators (3,000\u20138,000 RPM at the worm).<\/p>\n<\/p><\/div>\n

\n

Corrosion Resistance in Automotive Environment<\/h3>\n

Automotive worm gears are exposed to humidity (condensation in door cavities), automotive fluids (window washer fluid, brake fluid in adjacent areas), and salt spray in winter road conditions. Surface treatment by galvanising or zinc-nickel plating provides the automotive corrosion resistance test compliance (salt spray test ASTM B117: 240\u2013500 hours) required by automotive OEM supplier qualification standards.<\/p>\n<\/p><\/div>\n

\n

Self-Locking in Position-Holding Applications<\/h3>\n

Automotive seat position holders, mirror fold position holds, and window-up end-of-travel positions all benefit from the worm gear’s self-locking property. The seat must not drift from the adjusted position when the motor is off; the mirror must hold its angle in wind pressure without motor power. Korea Ever-Power calculates and confirms the lead angle for every automotive worm gear pair to verify self-locking is maintained at the specified motor shaft thread geometry.<\/p>\n<\/p><\/div>\n<\/div>\n
