FAQ

Grinding wheel for grinding hob

White corundum is not good, we've also used it, the efficiency is low, the old want to repair the wheel, now back to the jade white jade et al than use a lot.

What's the difference in shape and function of the shaper cutter, shaving cutter and gear hob?

There are pictures and documents in the attachment, and the processing methods and principles of each tool are explained

Hobbing machine hob installation angle is wrong, what will happen?Go to work in the middle of the hob stopped, and then use the manual to hob vertical movement, and then start the workpiece and why card and the card hob is bad? And the consequences?

The general accuracy, generally a twice fine, roll into half in the dynamic angle (angle between the roll angle transform, gear hob axis and a position transform) cutter and gear blank is not the tooth socket overlap, serious breakage, the workpiece is not serious waste.

Known gear hobbing machine speed, knife, and hob modulus, the number of teeth of the workpiece, the processing thickness (Chi Kuan), how to calculate the processing hours?

The thickness is divided by the speed divided by the number of teeth multiplied by the knife.. Minutes.. It doesn't matter the size of the module..

Recently, the design of gear hobs and their machining helical gears have been studied! Encountered some problems, I would like to ask for advice! Given the modulus, pressure angle, surface and axial dimensions of gear hob basic parameters such as displacement coefficient which is? There is the use of gear hob to process a bevel gear, the workpiece rotates, a tilt angle of the cutter, moving from top to bottom, is excuse me, the method of helical gear surface machined out of the relationship with the gear hob surface and axial dimensions, is gear hob surface, generating the the method of helical gear surface size?

The normal dimension of helical gear, if the surface of gear hob is out of gear, is the surface of helical gear involute?

What is the number of hob head?

De=DH 2ms type, De-- worm gear, outer diameter DH--, worm throat diameter, ms-- modulus, mechanical design manual, find the outer diameter of about 190 mm

If a pair of conjugate gears have different coefficients, can the hob be used in general? The addendum of the tooth is required

We know that a pair of angle changing gears with unequal coefficient of change is not equal to 0, and his teeth are of different height. However, the tool edge is in accordance with the hob to pitch circle root circle direction follow certain dimensions of manufacturing tool edge starting point, and the gear tooth height because the modification coefficient is not the same as the height difference, top gear and gear tooth tangent, and this kind of hob is. The gear tooth top to the edge starting point is fixed, then the gear is cut after the addendum modification on the size difference is too much, so the hob is not universal

How about the front edge, the normal and the normal tooth shape of the hob with rake angle?

The reference rack tooth shape (normal tooth shape) is unique. It is the mother of other tooth forms. So, no matter what type your knife is made of, its original baseline rack profile is the same, so that the required piece of work can be cut.
