How about the modulus of bevel gear?
The center distance is an indispensable parameter because it determines the coefficient of displacement of the pinion. If the height is shifted, the calculation is very simple. The modulus pressure angle of the pinion and the big gear must be equal, which is the basic condition of the conjugate. The number of teeth is 13, and the coefficient of displacement is 0.5. If the angle is shifted, the center distance must be known. With the center distance, the coefficient of displacement of the pinion is inverted and all geometric parameters can be calculated. If you are not the center distance, is not limited by the structure of words, you can be in accordance with the small gear undercutting to calculate displacement modulus "it refers to the ratio of the same side gear tooth profile between the adjacent two teeth from T and PI (M = t/, PI) in millimeters. Modulus is one of the most basic parameters of modular gear teeth.
The larger the modulus, the higher the gear is, the thicker the gear, and if the number of teeth of the gear is fixed, the radial size of the wheel is greater. Modulus standards are based on requirements such as design, manufacture and inspection. For non straight tooth gear, modulus difference method to modulus Mn, face modulus MS and axial modulus MX, they are in their respective pitch (normal pitch, tooth distance and axial pitch) and PI ratio are in millimeters. For bevel gear, me, average modulus big endian modulus modulus mm and the modulus M1 of the small end. For tools, there is a corresponding cutter modulus, Mo, etc.. Standard modulus is widely used.
Modulus and pressure of the bevel gear and the end, is the standard value, can be found in the tables. Equivalent number of teeth is big teeth divided by the cone angle cosine value.
The standard modulus is the basic parameter in metric gear drive, worm drive, synchronous belt drive, ratchet wheel, gear coupling, spline and so on. It plays a basic role in the design, manufacture and maintenance of the above parts (see cylindrical gear drive, worm drive, etc.). Coefficient, calculate all geometric parameters, on the basis of the calculated modulus is one of the basic parameters of gear size calculated from the center, symbol "m". Saidpopular. D like clothes number, the greater the modulus, the size of each part of the gear with proportionally increased, teeth can withstand the power is big. Specifically, the modulus is two teeth (in reference circle) is the arc length dimensions in millimeters, the relationship between modulus and the outer diameter of the gear is: diameter = modulus * (+2 number) modulus of uniform standard. So each place to produce gear to intermateable.
