FAQ

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 gear grinder is out of order and the gap is a bit too big
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
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?
Grinding wheel for grinding hob
LZ uses the five axis linkage tool grinding, the good machine tool certainly must match the good tool! The grinding wheel should be CBN, with a particle size of 100-120.
When machining M3 worm gear on Y3150 hobbing machine, how to determine the rotation angle and direction of hob cutter head?
Pressure angle, vortex data can be calculated, Wenling Kaisheng machinery specialized hob, broach, milling cutter, gear machining
Does the forum superiors in the gear hobbing process, because the workpiece in addition to generating motion, and an attachment movement for generating helical gear so I want to ask the question is to spur gear hob, turning a lead, the workpiece will rotate (360* / gear hob the number of degrees) for helical gear hob the same rotation of a lead, because of the additional movement of the workpiece, the workpiece rotation degree will be how much? PS: suppose the hob is the same as the gear rotation
This has something to do with your axial feed speed. It should be the angle increase of the straight gear (360 degrees / gear lead) * feed speed
What is the number of hob head?
What is a single head hob? What is the number of hob heads: the number of heads (the head number or the number of teeth in the same law)Roll vortex due to vortex with a single head, double head, three head, it should also have the corresponding hob single head, double head, three points, often double or three units lack of hob can only use single head instead, how may be close to the workpiece in drawings is a technology problem.What is the fixed number: the amount of the call is only the quantitative numberIn hobbing adjustment, need to compute three gears, namely indexing hanging round I, feed, hanging wheel i: and differential gear i:. formula i_1=A_1 - Z_1/ (Z+ Z)...... (1) i_2=A_2 & f...... (2) i_3= (n - A_3 (+) /Z_1 (| Delta Z|) + /f (sin beta) / (n - m_n))...... (3) in the formula: A_1 - rolling gear machine indexing set number; A_2 rolled into a given number of gear machine; A_3 hobbing machine differential number; F hob vertical feed amount (mm/r); Z_1 - hob; Z - gear tooth number; Z supplement (micro workpiece tooth number the number of teeth), | Delta Z|
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.
