Problems solved by technology

[0004] (1) The tooth shape is narrow, making it difficult to double the torque strength that the gear can withstand
[0005] (2) The precise design and manufacturing process of the tooth profile are more complicated
[0007] Since the gear came out hundreds of years ago, the scientific and technological circles at home and abroad have done a lot of research experiments on the design and precise machining of the tooth profile of the gear. Although the gear transmission performance has been continuously improved and tended to the ideal limit, none of them another major breakthrough

Embodiment Construction

[0025] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0026] (1) Referring to Figure 2, first determine the number of teeth z of the two gears according to the estimated value of the gear diameter and the transmission ratio 1 ,z 2 and the radius R of the addendum circle 4 of the driving wheel or driven wheel d1 or R d2 value.

[0027] (2) by the number of teeth z 1 ,z 2 Directly calculate the central angle 3 corresponding to the tooth end 1 or the dedendum 2, that is, the rotation angle θ that the teeth should be staggered when two gears are coaxially superimposed in the wide-tooth superimposed gear 1 , θ 2 . Or the maximum central angle at which the planetary gears should be staggered when the planetary gears are in continuous meshing transmission. It is also the minimum central angle by which the teeth of wide-toothed helical gears must be rotated and tilted.

[0028] (3) Radius R of addendum circle 4 ...

Abstract

The invention relates to a method for producing wide-tooth gear used in power gear, which can be divided into wide tooth layer gear, wide tooth combine planet gear and wide tooth incline gear via different gear methods. The inventive tooth width is 1.2 times than present gear, while the torque of single tooth is 1.5 times of present one, with low cost and long service life, while the invention can save more than 40% material.

Description

technical field [0001] Power transmission gears inside various mechanical equipment. Background technique [0002] The existing gear tooth profiles designed and manufactured by the gear industry at home and abroad mainly include involute, arc and double arc gears. In recent years, my country has imported cycloidal bevel gears and hypoid gears from Europe and the United States, as well as harmonic gears designed by the former Soviet Union. Check the gear parts of recent imports and domestic high-end automobiles, and retrieve the invention and utility model patent announcements of China's F16H class since 1985 from the Internet, all of which belong to the gears of the above-mentioned contour tooth profile. [0003] The above-mentioned gears of various tooth profiles all have the following deficiencies: [0004] (1) The tooth shape is narrow, which makes it difficult to double the torque strength that the gear can withstand. [0005] (2) The precise design and manufacturing ...
