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

Metal internal gears<\/strong> are the broadest-range ring gear product Korea Ever-Power manufactures \u2014 covering module M0.15 through M3.0, diameter \u03a63 to \u03a6120 mm, in 11 material options from POM through tool steel. The defining feature of this product family is the popular large-size metal internal gear: low cost, suitable for many applications, large in size and number of teeth, and capable of being used as segment gears by cutting. The ability to cut a full-circle metal internal ring gear into segments \u2014 arc sections of 60\u00b0, 90\u00b0, 120\u00b0, or custom angles \u2014 is particularly valuable for installations where a full-ring mounting is not possible due to shaft or housing interference, or where the ring gear is too large to ship as a single piece.<\/p>\n

Korea Ever-Power is one of China’s leading manufacturers of metal internal gears<\/a> with over ten years of experience and hundreds of qualified personnel. 100% QC before shipping. Free samples available (1\u20132 days after specification confirmation; freight paid by customer). Factory visits welcome. Agent and distributor cooperation available. Quotation within 24 hours. ISO 9001:2008 \/ TS16949.<\/p>\n<\/p><\/div>\n<\/div>\n

Metal internal gears provide a compact parallel shaft transmission drive with considerable speed reduction. An internal gear is a gear with its teeth cut in the internal surface of a cylinder and meshes with spur gears. The broader module range of this product (to M3.0, versus M2.2 for the automotive variant) specifically covers the larger-module industrial and construction machinery planetary ring gears where the tooth size, face width, and blank OD place the gear in the industrial heavy-duty category rather than the precision fine-pitch automotive category.<\/p>\n

Segment Gear Capability \u2014 Large Ring Gears Cut to Arc Sections<\/h2>\n

\"types<\/p>\n

Large metal internal ring gears can be used as segment gears by cutting \u2014 dividing the full-circle ring gear into arc sections (segments) of 60\u00b0, 90\u00b0, 120\u00b0, or custom angles. This capability is particularly valuable for two application types:<\/p>\n

\n
\n

Installations Where Full-Ring Mounting Is Impossible<\/h3>\n

In some machinery retrofits or replacements, the ring gear’s mounting location is not accessible for a full-ring installation \u2014 a bearing, shaft collar, or structural member blocks the insertion path. By cutting the ring gear into two or three segments, it can be installed around the obstruction and bolted together with precision alignment features. Korea Ever-Power’s large metal internal ring gears are precision-cut at the segment boundaries with matched reference surfaces and dowel pin holes to ensure the assembled segments produce the same tooth accuracy as the original full-circle ring.<\/p>\n<\/p><\/div>\n

\n

Ring Gears Too Large to Ship as Single Piece<\/h3>\n

Very large ring gears (above approximately 800 mm OD for sea freight; above 400 mm for air\/express) may exceed the practical dimensional limits of international shipping containers or air freight pallets in their full-circle form. Cutting the ring gear into 3 or 4 segments reduces the maximum dimension from the full OD to approximately 60\u201370% of the OD, making the segments shippable in standard packaging. The segments are precision-marked and match-bored at the joint faces for assembly alignment at the installation site.<\/p>\n<\/p><\/div>\n

\n

Partial Arc Engagement Applications<\/h3>\n

Some mechanism designs require only a partial arc of internal gear teeth \u2014 a sector ring gear that engages the pinion over a limited angular range corresponding to the mechanism’s working stroke. For example, a windscreen wiper drive mechanism may use a 120\u00b0 sector internal gear; an automotive seat recline mechanism may use a 90\u00b0 sector ring gear. Korea Ever-Power cuts full-circle ring gears to the required sector arc angle, with precision end faces and any required mounting holes or brackets.<\/p>\n<\/p><\/div>\n<\/div>\n

Customer Reviews<\/h2>\n
\n
\n

“We needed large metal internal ring gears M2.5 as segments \u2014 the installation site had a bearing flange blocking full-ring insertion. Korea Ever-Power cut the full-circle ring into three 120\u00b0 segments with matched dowel pin bores at the joint faces. All three segments assembled to correct tooth position on our installation alignment check. 100% QC inspection report included. Free sample confirmed segment cut accuracy before we ordered the production batch.”<\/p>\n
