A drawing in DWG, PDF, or STEP format is strongly preferred. For replacement gears from worn parts: send the worn gear \u2014 Korea Ever-Power measures all parameters by gear analyser and confirms material by OES spectrometer, typically within 5 working days.<\/p>\n<\/div>\n<div style=\"border-bottom: 1px solid #e0e0e0; padding: 14px 0;\">\n<p><strong style=\"font-size: clamp(14px,2vw,17px); color: #1a5276; line-height: 1.85; margin-bottom: 7px; display: block;\">Can I replace a helical gear with a spur gear of the same module and tooth count?<\/strong><\/p>\n<p style=\"font-size: clamp(14px,2vw,17px); color: #2c3e50; line-height: 1.85; margin-bottom: 0;\">No. The pitch diameter of a <strong>roda gigi heliks<\/strong> is d = Mn \u00d7 z \/ cos \u03b2, whereas a spur gear with the same Mn and z has d = Mn \u00d7 z. The centre distance changes, and the mating gear and housing positions must all be redesigned. Always replace a <strong>roda gigi potong heliks<\/strong> with a matching helical gear of the same normal module, tooth count, and helix angle.<\/p>\n<\/div>\n<div style=\"border-bottom: 1px solid #e0e0e0; padding: 14px 0;\">\n<p><strong style=\"font-size: clamp(14px,2vw,17px); color: #1a5276; line-height: 1.85; margin-bottom: 7px; display: block;\">How do I choose between gear hobbing and grinding?<\/strong><\/p>\n<p style=\"font-size: clamp(14px,2vw,17px); color: #2c3e50; line-height: 1.85; margin-bottom: 0;\">Soft-tooth (QT, HB 220\u2013320) or induction-hardened gears operating below 20 m\/s: precision hobbing to DIN Class 7\u20138 is usually sufficient and lower cost. Carburized gears (HRC 58\u201362): grinding is essential to correct heat treatment distortion \u2014 without it, accuracy degrades to Class 7\u20139 regardless of hobbing quality. DIN Class 4\u20136 applications (automotive, CNC, railway): tooth grinding is required regardless of heat treatment method.<\/p>\n<\/div>\n<div style=\"border-bottom: 1px solid #e0e0e0; padding: 14px 0;\">\n<p><strong style=\"font-size: clamp(14px,2vw,17px); color: #1a5276; line-height: 1.85; margin-bottom: 7px; display: block;\">What is the typical lead time from Korea Ever-Power?<\/strong><\/p>\n<p style=\"font-size: clamp(14px,2vw,17px); color: #2c3e50; line-height: 1.85; margin-bottom: 0;\">Small gears (M1\u2013M12, OD \u2264 200mm) in stock materials: 15\u201320 working days. Medium gears (M12\u2013M30) with carburizing and grinding: 4\u20136 weeks. Large gears (OD &gt; 500mm): 8\u201314 weeks. For mill-down or vessel dry-dock urgencies, contact with your required delivery date \u2014 Korea Ever-Power confirms the fastest achievable schedule based on current production loading.<\/p>\n<\/div>\n<div style=\"border-bottom: 1px solid #e0e0e0; padding: 14px 0;\">\n<p><strong style=\"font-size: clamp(14px,2vw,17px); color: #1a5276; line-height: 1.85; margin-bottom: 7px; display: block;\">Can profile modifications like tip relief and lead crowning be specified?<\/strong><\/p>\n<p style=\"font-size: clamp(14px,2vw,17px); color: #2c3e50; line-height: 1.85; margin-bottom: 0;\">Yes. For noise-critical and high-performance applications, profile modifications are often essential. Tip relief reduces dynamic load at tooth entry and exit. Lead crowning compensates for shaft deflection under load, keeping contact centred in the face width. End relief prevents stress concentration from misalignment. All modifications are specified on the gear drawing and implemented during the H\u00d6FLER tooth grinding operation.<\/p>\n<\/div>\n<div style=\"padding: 14px 0;\">\n<p><strong style=\"font-size: clamp(14px,2vw,17px); color: #1a5276; line-height: 1.85; margin-bottom: 7px; display: block;\">Does Korea Ever-Power accept single-piece orders?<\/strong><\/p>\n<p style=\"font-size: clamp(14px,2vw,17px); color: #2c3e50; line-height: 1.85; margin-bottom: 0;\">Yes \u2014 MOQ is 1 piece for all materials, sizes, and heat treatment grades. Prototype and maintenance-replacement single-piece orders are standard.
