【正文】 s the tooth surface. It is the gradual meshing gears and smooth teeth from one tooth to another, passing movement that makes highspeed helical gears under heavy load with the ability to transmit motion smoothly. Helical gear shaft bearings to withstand radial and axial force. When the axial thrust of a big change or due to other reasons, have some impact, then you can use the herringbone gear. Double helical gear (herringbone gear) is mounted side by side with the reverse on the same axis is equivalent to two helical gears. They have the opposite effect of axial thrust, thus eliminating axial thrust. When two or more unidirectional bevel gear to be on the same axis, the gear39。 5. Cone。 T method, this method is to provide highspeed steel tool temperature distribution for more information. The technology is based on metallographic crosssection of high speed steel cutting tools on a test basis, the purpose is to create change in microstructure and thermal changes of Chart relationship. When processing a wide range of workpiece material to the time, Trent has been discussed in highspeed steel cutting tool measured temperature and temperature distribution methods. Because this technology has been used scanning electron microscopy further development objective is to study a variety of martensite has been back to the fire and return fire, the structure of the highspeed steel microstructure caused by changes in the microstructure. This technology is also used to study singlepoint turning and high speed steel twist drill temperature distributions. Tool wear Has been treated from many brittle and crack edge tool in the known, there are basically three types of tool wear: flank wear, rake face wear and Vnotch wear. Both occurred after the flank wear also occurred on the main blade Vice blade. On the main blade, because the task responsible for removal of most of the metal chips, which leads to increased cutting force and cutting temperature increase, if not allowed to check processing, that may lead to vibration of the tool and the workpiece occurs and the conditions that may no longer be effective cutting Exist. Viceblade on it is to determine the size and surface finish of the workpiece, the size of flank wear may cause failure of the product and the surface finish is also poor. In most practical cutting conditions, because of the rake face before the Lord Deputy rake face wear, wear to reach large enough, the tool will be effective, the result is made of substandard parts. Because the tool stress distribution on the surface uneven, sliding between the chip and rake face contact zone stress in the sliding contact area of the start of the largest contact area in the rear is zero, so that abrasive wear occurred in the region . This is because the settlements in the vicinity of the cutting card is more serious than the near edge wear, and the blade near the chip and rake face due to loss of contact wear lighter. This results from the cutting edge at a certain distance from the surface of the formation of pitting before the pit knife, which is generally considered the rake face wear. Typically, this wear crosssection is rounded. In many cases, and for the actual cutting position, the rake face wear of flank wear than the lighter, the flank wear as a tool failure, more generally, the scale mark. However, because many authors have expressed increasing cutting speed, as the case, the first blade surface temperature than the surface temperature rise after the knife faster, but also because of the wear rate is essentially any form is subject to significant temperature changes Impact. Therefore, the rake face wear usually occurs when highspeed cutting. The main tool flank wear with the tail was not p。 3.
