Roll, Shaper: processing equipment used in the tooth department still uses a lot of common hobbing and slotting machine spur production, although the adjustment easy maintenance, but lower production efficiency, larger capacity if needed to complete the multi-machine production simultaneously. With the development of coating technology, hob, insert the blade again after grinding Tudu very easily, after coating can significantly improve tool life, increased by more than 90 percent generally straight gear factory, effectively reducing the number of tool changes and grinding time, efficiency significantly. Luoyang Fuyuan various gears Gear Machinery Co., Ltd. specializes in producing bevel gears, shafts, plates, etc., please come to order. Measuring tip diameter Dm method: First count the spur gear teeth Z bar, and then measure the tip diameter Dm with a vernier caliper, if it is determined the modular system is standard gear tooth spur gear, it's modulus: m = Dm / Z + 2 if it is determined that the diameter control standard tooth gear, its diametral pitch is Dp = 25.4 * (Z + 2) / Dm, however, be noted that, if the gear is an even number, be measured directly; small spur gear trustworthy _ _ Fuyuan spur gear provided 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.
