Embodiment Construction

[0030] Concrete implementation steps of the present invention are as follows:

[0031] The first step: according to the principle of Klingenberg bevel gear tooth surface machining, establish an accurate three-dimensional model of gear teeth

[0032] Step (1): Establish gear tooth machining coordinate system and tooth surface mathematical model

[0033] Klingenberg bevel gears are cycloidal bevel gears with equal-height teeth, that is, the tooth line in the tooth length direction is an extended epicycloid, and the tooth height is equal along the sub-cone busbar. The processing method of Klingenberg bevel gear adopts the full generation method, that is, the tool shaft cannot be tilted, and the contact area of ​​the tooth surface is controlled by adjusting the center offset of the inner and outer tool rotation and the radius of the outer tool for synchronous rotation. figure 1 Schematic diagram of a cycloid tooth incisor.

[0034] According to the structure and motion character...

Abstract

The invention discloses a Klingelnberg bevel gear contact regulating method. A recognition method comprises the following steps that (1) a gear processing coordinate system is built according to the Klingelnberg bevel gear processing theory, a wheel tooth surface equation is deduced according to a tool nose one-point equation, the equation is processed, and a wheel tooth three-dimensional model is obtained; (2) the built wheel tooth three-dimensional model is utilized, and the contact trace change rule of the gear is studied under the external load effect through Abaqus software simulation; and (3) the preloading is implemented after the practical installation according to the wheel tooth contact trace change rule and the variable load obtained in the second step, and the position of the wheel tooth contact region is checked. The contact region is best regulated to the small end, so the stressed contact region is right positioned in the middle position of the gear surface, the condition that the contact region is out of the gear surface when the wheel tooth suffers the heavy load can be avoided, the wheel tooth damage is avoided, the bearing capability of the gear is improved, important theoretical basis is provided for reasonably and economically improving the transmission accuracy of a Klingelnberg bevel gear, and the effective reference is provided for the installation of the Klingelnberg bevel gear.

Description

technical field [0001] The invention relates to a method for adjusting the contact of a Klingenberg bevel gear, which belongs to the field of mechanical design and manufacture. Background technique [0002] Klingenberg bevel gears have the advantages of high coincidence, stable transmission, and high load-carrying capacity. Widely used in various mechanical equipment, such as automobiles, construction machinery, rotor-propelled helicopters, machine tools, etc. The manufacturing accuracy and quality of Klingenberg bevel gears directly affect the efficiency, noise, motion accuracy and life of these devices. Therefore, Klingenberg bevel gears have been widely concerned and researched by relevant experts and scholars from various countries, and have become a medium in gear production. The key technologies and commanding heights. The meshing contact area of ​​gear teeth is a comprehensive index to measure the quality of gear transmission. If the contact area is large, small, sh...
