Miter Gearbox Request For Improvement
Miter Gearbox With the development of automotive production technology and the use of the requirements of the increase, the automotive gear is moving towards high precision, high strength, Miter Gearbox high load, low noise, lightweight and long life direction, thus the gear processing technology put forward higher requirements. The chamfering of the gear teeth is a very important process measure to control the gear noise, Miter Gearbox which has aroused the attention and attention of the gear manufacturing and manufacturing industry at home and abroad.
The chamfer is essentially a small chamfer, Miter Gearbox that is, all the exposed sharp corners after the tooth profile of the gear, and then a small chamfer, in order to have a large chamfer at both ends of the gear (that is, Angle) phase difference, it is called chamfering. Miter Gearbox Chamfering is divided into the following two: tooth top chamfer and tooth profile chamfering
The chamfer is an important measure of the chamfering along the end face of the teeth to prevent noise and damage from engaging the tooth surface due to the small bumps.
A pair of gears in the process of engagement, Miter Gearbox the beginning of the engagement, due to processing and deformation of the teeth, easily lead to impact, so the vibration increases.
Large and small gears in the operation, Miter Gearbox if you do not use the top of the tooth, then often appear in the pinion gear teeth of the tooth root. This is because the size of the gear teeth of the outer ring is generally harder than the tooth root, and where the sliding speed is larger, Miter Gearbox coupled with the improper adjustment when installed, so after the operation of the size of the gears are often the top of each other Of the tooth root, easy to draw groove marks similar to gluing, sometimes the pinion tooth tooth tooth surface also draw the same groove marks, the gear life has a serious impact.
After chamfering to eliminate the tooth tip and tooth profile sharp corners have the following benefits:
(1) In the induction hardening of the gear, Miter Gearbox the intermediate frequency, especially the high frequency heating, tends to overheat at the sharp corners. Therefore, Miter Gearbox the gear teeth must be chamfered before quenching in order to obtain the best quenching effect during the heat treatment.
(2) on the hardened gear, carburizing before the appropriate heat before the chamfer (preferably rounded), in the heat treatment carburizing process to avoid the rotation of the teeth at the corners of the oxidative decarburization.
(3) to reduce the stress concentration during quenching to reduce and eliminate the heat treatment process caused by quenching cracks or cracking, Miter Gearbox which for the prevention of quenching cracking has an important role.
Modern heavy-duty hardened gears are not simply dependent on the grinding machine to ensure the accuracy of grinding, many domestic and foreign enterprises have successfully carried out to scratch the grinding process, whether external or internal teeth are carbide tools Hardened surface for scraping. As the hardened face after chamfering, is conducive to the cutting of the tool, Miter Gearbox which can effectively avoid the knife and chipping the knife. For the hardened surface to scratch the grinding process, scraping before the hard side of the face, is very important and must be a work.
Gear gear chamfer is to ensure that the quality of gear can not be used to ignore the important process,Miter Gearbox according to the gear in the box in the position and role of its tooth end chamfer processing requirements are also different.
