Q:Help your heroes: what exact parameters do you need to draw accurate spiral bevel gears?
3, adjust the parameters of machine tools. The 2 and the 3 is the key to the calculation of the model, in which you need to get is: take the time or the spindle rotation is variable, through the cutter rotation motion of each axis of the machine tools will be on the knife disk space position of each point determined, so many points will be composed of a tooth. Then use special software for no-load contact analysis to see his meshing condition
Q:What about the spiral bevel gears and spiral bevel gears?
The spiral bevel gear has an arc shape, a spiral angle, and a conical tooth shape (see Figure)Because the tooth surface of spiral bevel gear is very like an umbrella, it is also called spiral bevel gear, arc tooth bevel gear, spiral bevel gear, circular arc bevel gear and so on
Q:What are the functions of worm gear sets and conical gears?
Worm gear set: This is a problem of Oh, you say should be a worm, great reduction rate, the input shaft and the output shaft angle of 90 degrees is generally high. Since the work with unequal tooth surface friction is serious, the work efficiency is low and the transmission is not reversible, much need for large reduction ratio place
Q:Are the coefficient of tooth width of straight bevel gears and spur gears the same?
Unlike the spur gears, the gears are arranged according to the arrangement of the transmission gears
Q:Why can't the tooth width of straight bevel gear be too big?
The tooth of a straight bevel gear is progressively tapered from the outside to the cone, for example, a 3 modulus bevel gear, if the width of the tooth reaches 1/3 of the cone generatrix,
Q:About the diagonal contact of spiral bevel gears?
The outside diagonal is absolutely not allowed, and the proper inner diagonal can reduce the contact noise
Q:Where does the center distance of bevel gears go from there?
As with cylindrical gears, the sum of the middle radius of gear two
Q:The main function of gear drive is
The bevel gear drive is used to transfer the motion and power between the two intersecting shafts
Q:Strength of bevel gearsA pair of closed straight bevel gears, which need reciprocating operation (i.e., positive and reverse).
(1) force analysis of gear teethWhen calculating the strength of a gear, it is first necessary to know the force on the gear, which requires the analysis of the force acting on the gear. Of course, the force analysis of the gear drive is also necessary to calculate the shaft and bearing of the gear.Generally, the gear drive is lubricated, and the friction between the meshing teeth is usually very small. The calculation of the force of the gear teeth can not be considered.The normal load Fn acting on the gear surface along the meshing line is perpendicular to the tooth surface. In order to facilitate the calculation, the normal load Fn is broken into two mutually perpendicular force components at the node P, namely the circumferential force Ft and the radial force Fr,
Q:Can the two - stage bevel gear reducer use spur gear?
Compared with the straight bevel gear, the spiral bevel gear has the least available tooth number and more stable transmission, but the machining is difficult and the cost is high
