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: 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?: For the share, I'll tell you. The angle is shifted, the hob's pitch is wrong. The back angle is also easy to take off.. If you move back, you'll certainly get stuck. With hob is also a certain relationship. Wenling Kaiyuan tool factory this kind of strength brand hob generally won't card bad. Don't forget to give me a bonus!!!!

Q: What's the difference in shape and function of the shaper cutter, shaving cutter and gear hob?: The shaper cutter is like a straight gear, and the front face of the cutter is concave taper in order to form the rake angle, and the machining accuracy of the gear is higher (than hobbing).The shaving cutter is like a helical gear, and the cutter teeth are arranged in a longitudinal groove, which is used for fine machining after slotting and hobbing.The hobbing cutter is shaped like a worm and is arranged along the axial direction, and belongs to the rack type gear cutter.

Q: The circular cutter mould heating cutting pearl cotton machine, mainly to do with the machine last name? Where can I get it?: I have seen this kind of equipment as fast as possible, and the product is as fast as running water

Q: What are the main causes of hob breaking?: (1) helical rolling wheel indexing hanging off, (Y38-1, Y3150) indexing hanging round off, the table does not turn, turn the cutter knife, broken teeth. The differential gear shedding (Y3150E, Y3180H) differential gear off the bench or turn. (2) head screw clearance large, in the processing process, the knife suddenly sank (inverse milling often), caused by the amount of feed is too large, not only from the sometimes broken tooth hob groove crack, the entire knife scrap (3) processing the material hardness is too high or too soft, also to the broken tooth cutter

Q: Experts, EG, how much is the hobbing hob used in the actual production of engagement? Feed rate? What is the effect of spindle speed, machining accuracy? What is the M2 M2.5 M3 M3.5 M4 M5 / M6 M7 M8 M9 M10 engagement, the lathe is Chongqing 3180 thank you teachers, generous with your criticism: Feed standard gear is 2.25* modulus relationship of gear spindle speed and machining, Y3180 hobbing machine workbench is the maximum speed of not more than 5 minutes per turn, speed is too fast, the worm attached table soon wear out.

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: The difference between the gear hobbing machine hob hob with single and multi line please tell me what it is: Multi thread hob is long hob, 2 to 3 head, high efficiency, the processing of gear precision is lower. Single track hob is a single head hob, relatively speaking, the processing of gear less efficient, higher processing accuracy. The head number is also called the number of teeth. The number of teeth of the hob is not the number of teeth cut in a circle. That is called the number of grooves, which is easily mistaken for those who are not in the trade.

Q: 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

Q: When the gear hobbing machine, gear hobbing cutting depth increases, the cutter shaft transmission box a gala Gala of the strange sound, returned from the new start roll disappears, each gear case, open the inspection found no gear hob shaft breakage, pressure bearing clearance, from the new installation and debugging after the situation remains the same, this is what's the matter?: The pressure has increased
