Embodiment Construction

[0015] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0016] like Figure 1~3 As shown, an asymmetrical involute worm helical gear pair includes a worm 1 and a helical gear 2. The two sides of the teeth of the worm 1 have a worm meshing side tooth profile 3 and a worm non-meshing side tooth profile 4 respectively, and the helical gear 2 The two sides of the gear teeth of the helical gear have the meshing side profile 5 of the helical gear and the non-meshing side profile 6 of the helical gear, wherein the axial modulus of the worm 1 is m 1 , the end modulus of the helical gear 2 is m 2 , the pressure angle of the tooth profile 3 on the meshing side of the worm is α 1 , the pressure angle of the tooth profile 4 on the non-meshing side of the worm is α 2 , the pressure angle of the tooth profile 5 on...

Abstract

The invention discloses an asymmetric involute worm and bevel gear pair. The asymmetric involute worm and bevel gear pair comprises a worm and a bevel gear, the two sides of gear teeth of the worm are provided with a worm mesh side tooth profile and a worm non-mesh side tooth profile respectively, and the two sides of gear teeth of the bevel gear are provided with a bevel gear mesh side tooth profile and a bevel gear non-mesh side tooth profile respectively, wherein the axial modulus of the worm is m1, the end face modulus of the bevel gear is m2, the pressure angle of the worm mesh side tooth profile is alpha1, the pressure angle of the worm non-mesh side tooth profile is alpha2, the pressure angle of the bevel gear mesh side tooth profile is alpha3, the pressure angle of the bevel gear non-mesh side tooth profile is alpha4, and the following conditions are met: a, alpha1>alpha2, and alpha3>alpha4; b, when m1=m2, alpha1=alpha3, and alpha2=alpha4; when m1 is not equal to m2, m1cosalpha1=m2cosalpha3, and m1cosaplha2= m2cosalpha4. According to the asymmetric involute worm and bevel gear pair, tooth root fracture of the bevel gear can be effectively avoided, and the shock resistance and the bearing capacity of the asymmetric involute worm and bevel gear pair in transmission are improved.

Description

technical field [0001] The invention relates to an asymmetrical involute worm helical gear pair, which belongs to the technical field of helical gear worm mechanical transmission. Background technique [0002] At present, worm drive is widely used because of its advantages of large transmission ratio, stable transmission, small vibration and low noise. The performance and quality of worm transmission will ultimately affect the quality of machine products. Therefore, in order to meet the needs of modern mass production, the transmission performance of worm is required to be continuously optimized. In recent years, there have been great developments in the meshing theory of worm helical gears, calculation of bearing capacity, and new worm drives. In the process of worm drive, the shape of gear teeth will not only affect the kinematic characteristics of worm drive, but also affect the dynamic performance of worm helical gear drive. In order to adapt to the development trend o...
