Measuring tip diameter Dm method: First count the number of gear teeth Z, then measure the tip diameter Dm with a caliper, if it is determined the modular system is standard gear tooth spur gear plant, its modulus: m = Dm / Z + 2 if it is determined that the diameter control standard gear tooth, its diameter section is Dp = 25.4 * (Z + 2) / Dm, however, be noted that the spur gear even if the gear is, before direct measurements; Luoyang Fuyuan gear Machinery Co., Ltd. is the production of construction machinery, tractors and cars gear, shaft, disk parts, sell other products integrated manufacturing enterprises. With a variety of small, medium and large spur bevel gear and shaft, disk parts thirty thousand sets of annual production capacity. It is mainly with China First Tractor Group, Luoyang Construction Machinery, Luoyang dual Swiss Group, Luoyang locomotive factories and other units supporting the production gear, shaft and disc-type parts. The company's existing slotting machines, gear shaping machines, gear hobbing machine, a variety of grinders, milling machines, broaching machines, presses and other equipment. There are a full range of quality testing equipment gear and equipment. Company organization sound, have experienced production and marketing, warehousing, financial and other management personnel, a senior engineer, senior inspectors, high-ranking operational and technical teams. Gear: continuously meshing teeth transmit motion and power of mechanical components, it is capable of intermeshing toothed mechanical parts on the rim. Large diameter gear is double the diameter of the pinion. If the gear does not move, the pinion gear along the big revolution of the pinion rotation a few weeks? Conversely, if the pinion gear does not move straight bar, large pinion gear along the revolution of the large gear rotation a few weeks? Gear fixed vertical gear, the pinion along the gear revolution of the pinion gear rotates once; when the pinion gear does not move, the large gear along the pinion revolution of the large gear rotation week and a half, i.e. 240 ° position one rotation, 360 ° Location rotation week and a half, 480 ° rotation position two weeks, 720 ° rotation position for three weeks. Straight Gears | gear industry leader Fuyuan | spur gear by Luoyang Fuyuan Machinery Co. Luoyang Fuyuan gear Machinery Co., Ltd. (www.lyfycl.com) is a leader in Luoyang, Henan Province, gear over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
