Problems solved by technology

Various existing trimming methods assume that the tip of the diamond pen is an absolute point, but in fact, during the trimming process of the tip of the diamond pen, the radius of curvature at the top gradually increases, and cracks often occur, and the amount of change known to the diamond pen is 100μm level, and the grinding accuracy is 10μm level, that is, the noise is more than 10 bits larger than the signal. In these cases, the repaired grinding wheel is often the envelope of the irregular pen tip

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] Figure 1 and Figure 2 show the relationship between the involute and the arc of the tooth profile of the forming grinding wheel. The tooth surface of the gear is ground by the involute segments on both sides of the grinding wheel. Generally, the bottom groove of the gear is milled deeper, so The teeth of the grinding wheel do not work. But when necessary, the grinding wheel addendum can also work at the same time. First establish the coordinate system oxy on the grinding wheel, then the coordinate array of the involute segment on the grinding wheel can be calculated, with (x i ,y i )express. At present, there are many ready-made calculation methods, such as the least square method, three-point method, etc., which are used to calculate the approximate arc center O 1 The coordinates (x, y) and the arc radius r. Figure 2 shows the error situation when the arc appro...

Abstract

A method and equipment for truing the arc-based involute abrasive disk is disclosed. Said method includes creating a pair of truing devices composed of the mechanism for making diamond pen to do arc moement and the involute compensating mechanism, creating the reference part for measuring the radius of arc, shifting the dual-coordinate regulating mechanism for arc center, using said mechanism for generating arc movement to generate involute profile of tooth, and automatic and continuous truing by said compensating mechanism according to the calculated difference between involute and tooth profile.

Description

technical field [0001] The invention belongs to a gear processing method and device in the field of mechanical manufacturing. Background technique [0002] For large precision gears with hard tooth surfaces, if the generating method is used, one tooth groove must be ground dozens of times to form, and the production efficiency is very low. For example, the 4.5m developed gear grinding machine purchased in recent years costs about 50 million yuan and can only grind one or two 4-5m gears every month. [0003] If it is processed by forming method, the shape of the grinding wheel is the same as that of the tooth groove of the gear to be ground. Therefore, the tooth groove can be ground out at one time, and the production efficiency is many times higher. The key technical issue of profile grinding is how to repair an accurate involute grinding wheel, that is, what method and dresser to use. [0004] The existing trimming methods include profiling method, numerical control metho...
