背景技术Background technique
齿轮是机器中广泛采用的传动零件之一。比较常见的齿轮一般有斜齿轮和直齿轮两类,斜齿轮的优点使得其使用范围比直齿轮更广泛,所以在实际生产中经常使用到斜齿轮,而在使用过程中难免需要根据生产要求对斜齿轮半成品进行再加工。目前对于尺寸比较大且设有轴孔的齿轮通常采用齿轮端面和胀心轴相配合进行装夹,但对于没有轴孔的齿轮不适用;或者对于端面、轴孔跳动等精度要求比较高的齿轮,若使用该方法将导致齿轮端面及轴孔等达不到使用要求,在使用过程中易因跳动发生磨损,影响生产效益。Gears are one of the most widely used transmission parts in machines. The more common gears generally include helical gears and spur gears. The advantages of helical gears make them more widely used than spur gears. Therefore, helical gears are often used in actual production, and it is inevitable that they need to be adjusted according to production requirements. The semi-finished helical gear is reworked. At present, gears with large size and shaft holes are usually clamped by the gear end face and the expansion shaft, but it is not suitable for gears without shaft holes; or for gears with high precision requirements such as end face and shaft hole runout , If this method is used, the end face of the gear and the shaft hole will not meet the requirements for use, and it is easy to wear due to beating during use, which will affect the production efficiency.
