Who has done the relevant curriculum design, the design can be used for reference to me? Points I thank you, as for the mechanical design manual, what the book does not need to talk about
Straight bevel gear transmission design newmaker bevel gear bevel gear is short, it is used to realize the transmission between the two axis angle, S called axis angle, its value can be determined according to the needs of the transmission, the general use of 90 degrees. Bevel gear teeth are arranged in a truncated cone gear tooth, by end to end small gradually shrink, as shown below. Because of this characteristic, each cylindrical column in the cylindrical gear becomes cone in the bevel gear, such as indexing cone, joint cone, base cone, tooth crown cone and so on. The teeth of bevel gears include straight teeth, helical teeth and curved teeth. The design, manufacture and installation of straight and helical bevel gears are relatively simple, but the noise is large and used for low speed transmission (< 5m/s);
(2) straight bevel gears usually have a gearing ratio of 1~10 and a small gear tooth number of 16~30.(3) each tooth has a minimum number of teeth is to prevent undercutting in the gear hobbing. Therefore, it must be greater than the minimum number of teeth, the number of teeth to be set as odd as possible, preferably the number of teeth of a pair of meshing gears, each other as the prime number, at least not equal to each other integer multiples, so as to avoid the local teeth wear seriously.
(1) bevel gear is a bevel gear, it is used to realize the transmission between the two axis angle, S called axis angle, its value can be determined according to the needs of the transmission, the general use of 90 degrees. Bevel gear teeth are arranged in a truncated cone gear tooth, by end to end small gradually shrink, bevel gear tooth spur gears and helical gears and gear form curve.
The ratio of gear to bevel gear ratio of 1:3 is also 1:3. It is necessary to know the number of gear teeth in the base to determine the number of teeth of another gear, so the result is uncertain.
