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:Gear hob surface and shaft surface shape parameter is how to return a responsibility?
Because the hobbing process is along the normal direction, so we should know the normal form of the hob. This can be regarded as a rack, and the extension should be normal to the helical gear. But the design is basically not the same. Now computer operations are powerful, all through meshing calculations. The above point of view is for reference only...
Q:How to adjust the torque of disc hob commonly used in TBM?
The jack is adjusted by means of a jack mounted in different parts
Q:What does "hob" mean when cooking?
Correction: hob shall be hob block.Main points of hob block operation:The raw material is hob block roll up into pieces, to cut hob block must grasp three points; one is straight knife, two is the raw material and the knife angle between 45 to 60 degrees (about 70, three dollars is scissors) is every slice have to scroll a raw material, the rolling amplitude is determined you want to process massive size, is generally 1/3 weeks rolling material.Block cutting method of hob:1, a first bevel knife.2. Turn the section face up.3, in the 1/2 section (according to the block size and decided to cut the oblique).4, and then the last section of the plane turned upward.5, or about 1/2 oblique. This keeps turning over everything and turning everything over.
Q:What is the reason that the double gear hob changes the gear line of public gear too big?
Scraping the general process, scraping hob hob - modulation ---- carbide hob scraping. The general amount of stay, such as M5, usually leaves about 0.4. However, alloy hob is more valuable. Scraping hob must have roots, otherwise easily jump alloy hob tooth. Just say that.
Q: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?
It is very difficult, not numerical control, ordinary hobbing machine can only work experience, feel how much time a workpiece processing
Q:Gleason hob material marked as: G30 what material?
The estimate is similar to M35, because there is a higher grade of G70, which is equivalent to powder metallurgy high speed steel! I have seen their material introduction, and now I forgot
Q:What's the difference in shape and function of the shaper cutter, shaving cutter and gear hob?
Slotting cutters are cutters used on slotting machines, which mainly process internal and external gears. The hobbing cutter is a tool for processing gears on a gear hobbing machine. It can process gears other than internal gears. The shaving cutter is a cutting tool for shaving gears on a shaving machine, mainly finishing the gears. Structurally different
Q:Conjugate gears have different displacement coefficients, so can hobs be used in general?
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:The circular cutter mould heating cutting pearl cotton machine, mainly to do with the machine last name? Where can I get it?
Electric heating cutter, round hob, mould, heating, cutting, pearl cotton machine
