Abstract

The invention belongs to the technical field of bevel gear design, and particularly relates to a dot-line engaged bevel gear pair high in bearing capability and low in vibration. The dot-line engagedbevel gear pair high in bearing capability and low in vibration comprises a first bevel gear and a second bevel gear which are engaged with each other; the tooth number of the first bevel gear and thetooth number of the second bevel gear are taken as z1 and z2 correspondingly, the normal module of the first bevel gear and the normal module of the second bevel gear are taken as m<n1> and m<n2> correspondingly, the normal pressure angle of the first bevel gear and the normal pressure angle of the second bevel gear are taken as alpha<n1> and alpha <n2>, and the reference circle spiral angle of the first bevel gear and the reference circle spiral angle of the second bevel gear are taken as beta1 and beta2 correspondingly, wherein z1 and z2 meet the transmission ratio requirement and the convenient machining principle, and the values of m<n1> and m<n2> are selected in reference to the bevel gear handbook or customized according to needs; the values of alpha<n1> and alpha<n2> are selected according to transmission requirements, following relations are met, A), when z1 is smaller than z2, alpha<n1> is larger than alpha<n2>, alpha<n2> is larger than 20 degrees, and m<n1> is larger than m<n2>; B), when z1 is larger than z2, alpha<n2> is larger than alpha<n1>, alpha<n1> is larger than 20 degrees, and m<n2> is larger than m<n1>; the values of beta1 and beta2 are selected according to work needs, meanwhile, beta1 is equal to + / -beta2, '-' is taken for outer meshing, and '+'is taken for inner meshing. The provided dot-line engaged bevel gear pair combines the beneficial effects of dot-line engaged bevel gear and bevel gear joint outer meshing transmission at the same time and has the beneficial effects of being low in vibration, low in noise, large in strength and long in service life.

Description

technical field [0001] The invention belongs to the technical field of helical gear design, and in particular relates to a point-line meshing helical gear pair with large bearing capacity and low vibration. Background technique [0002] Helical gear transmission is widely used in various sectors of the national economy due to its advantages of high power, high efficiency, and long life. Its performance and quality ultimately affect the quality of machine products. Therefore, in order to adapt to the rapid development of modern mass production and technology, the performance of helical gear transmission is required to be continuously optimized. Especially in recent decades, great progress has been made in the meshing theory of helical gears, calculation and test of bearing capacity, vibration and noise, and new helical gear transmission. [0003] The point-line meshing helical gear is a new type of helical gear, that is, a pair of helical gear pairs meshing with each other. ...
