Embodiment Construction

[0016] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] figure 1 It is a schematic diagram of the matching structure of the face gear pair in the embodiment of the present invention, from figure 1 It can be seen that the face gear pair in this embodiment includes a face gear 1 and a small wheel 2 meshing with the face gear 1 . Wherein the face gear 1 is formed by cutting the profile wheel 3 and does not carry out tooth profile modification processing, while the small wheel 2 undergoes modification processing. figure 2 It is a schematic diagram of the structure of the small wheel 2 teeth 11 in the face gear pair of the embodiment of the present invention, wherein the broken line represents the shape of the small wheel before modification in this embodiment, and the sol...

Abstract

The invention provides a face gear pair which comprises a face gear and a small gear engaged to and matched with the face gear. The face gear pair is characterized in that a gear tooth of the small gear is cut by a plane parallel to the axis of the small gear to form an arc-shaped cross section; the thickness of the arc-shaped cross section is gradually reduced from the middle to the two sides; and an intersecting line between the arc-shaped cross section and the tooth face of the gear tooth is a curved line. Through axial direction correction on the small gear engaged to the face gear, the middle of the small gear is thick and the two sides of the small gear are thin in the tooth length direction of the small gear, so that an allowance of the small gear in an axial mounting process is raised, and the probability of generating an edge foundation due to a mounting error is lowered.

Description

technical field [0001] The invention relates to the technical field of gear transmission, in particular to a face gear pair. Background technique [0002] Face gear transmission is a form of transmission formed by the meshing of cylindrical gears and bevel gears. It has the advantages of compact structure, large transmission ratio, high coincidence, easy installation, and easy manufacture and replacement of pinions. It has great advantages in diversion and confluence. Advantage. Due to the above advantages, face gears are used more and more in transmission between intersecting shafts. Since the complete conjugate face gear pair is very sensitive to machining and installation errors, the ideal face gear transmission should be a partially conjugated face gear pair. In the prior art, the surface gear transmission is contacted by the difference in the number of teeth between the small wheel and the face gear. However, since the contact path is perpendicular to the root cone of...
