Q: 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

Q: What is the difference between worm gear hob and gear hob?: The most important thing is: worm gear hob and worm gear meshing with the worm, the outer diameter to be the same, the other tooth shape parameter is needless to say, should be the same!

Q: 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

Q: Hob mainly used for processing what?: Ordinary monolithic hob can cut the pizza, a high precision hob can cut softer materials such as rubber, patchwork, cutting. Mechanical hob is used in lathe processing, the type is not clear.

Q: 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?: To answer the first question of cross-section of a thread, is the shape and size of the axial section profile shaft open when the bus is also in this section marked normal profile refers to open along with the thread section perpendicular to the direction of the normal section size is in the size of this section for the second the problem, really is a little big, clear need space more, therefore, suggest that you download a book at the Forum (gear cutter design) the book look, on page 35 is down

Q: What do you think about the cutting hob?: Hob used for cutting, cutting out the shape of different blocks, similar volume, mainly used for Pier dishes to increase the shape of sensory effects, home braised beef / braised meat and other auxiliary materials, generally use this knife workCut hob basic attention is: cut a knife, rotating material 30-45 degrees, so that the cut out of different shapes, similar volume, to match the main ingredients

Q: How to judge the direction of hob rotation?: Wait a minute. When the ball is over, call again, just to see where the ball is going.

Q: What does "hob" mean when cooking?: The name of the hob block, not food, and irregular lumps, as long as the eggplant, cut the eggplant, cut, turn, turn, is the hob block

Q: What is the number of hob head?: The number or number of teeth in the same law

Q: Why is the front rake hob good for chip removal?: The last said will form a positive front angle, a negative front angle, that is, the two side cutting edges. A closer look at the last post, I found no hob for the main cutting edge discussed. The reason is to answer the question of positive and negative angles. The main rake angle is the front edge of the main cutting edge formed by the intersection of hob diameter and chip groove.
