Harmonic Unit Csf-25-120-2uh Of Hamanak Envelope Gear Grinding Machine

Harmonic unit CSF-25-120-2UH wave generator with internal transmission element wave, oval shape and flexible rolling bearing in outer ring. The number of external teeth of the flexible wheel is less than the number of internal teeth of the rigid wheel. When the wave generator rotates, the outer teeth of the flexwheel corresponding to the direction of the long axis are inserted into the inner teeth of the rigid wheel

Product Description

This is mainly because when calculating the template curve, an approximate arc passing through three points is used to replace the theoretical shape. Within the full length of the curve, the approximate arc may have concave or convex errors, and the harmonic unit CSF-25-120-2UH of the Harmonic Gear Grinding Machine may also have concave and convex errors. When measuring the tooth shape of the workpiece, the corresponding position of the involute tooth shape error of the workpiece should be found on the template, and then the shape of the corresponding part of the template should be gradually corrected with fine polishing sandpaper until the tooth shape of the workpiece meets the accuracy requirements.

After such adjustment, the tooth shape accuracy can reach 4^-5 levels, which can meet the general requirements currently proposed.

When grinding the tooth shape of the helical gear, it is carried out according to the "instant center-free enveloping method", and the grinding wheel axis is located in the normal plane of the tooth groove of the gear. Theoretically, in order to grind out the correct tooth shape, the axial section of the grinding wheel should not be the same as the end face shape of the gear tooth groove, nor should it be the same as the normal section of the gear tooth groove. It should be in the shape of a complex curve. However, since the calculation of the coordinates of this curve is quite troublesome, and the corresponding template is not easy to manufacture, in actual production, the helical gear is often regarded as a spur gear according to its normal equivalent number of teeth, and the tooth shape of the spur gear on both sides of the tooth groove is replaced by an approximate circular arc, and the template is manufactured according to the pseudo-island arc. Gear grinding with a worm wheel is continuously indexed, and the workpiece has a fast rotation speed, so among the various current gear grinding methods, this method is considered to be the most efficient.
