摘要
The present invention discloses a conjugate-curve-based multipoint-contact bevel gear pair. It includes a convex tooth gear and a concave tooth gear which are of multipoint contact, and the meshing surface of the convex tooth gear or the concave tooth gear is a tubular surface. The contact curve formed by the contact points on the tooth profile of the convex tooth gear and the contact curve formed by the contact points on that of the concave tooth gear are conjugate curves. The meshing manner of the conjugate-curve-based multipoint-contact bevel gear pair of the present invention is that the convex tooth gear and the concave tooth gear are simultaneously in a multipoint contact situation. All the contact traces of the contact points on respective tooth surfaces are smooth space curve. Such transmission inherits meshing characteristics of conjugate curves, and the tooth profile of point contact has high contact strength, large bearing capacity, a high transmission efficiency, a low lubricating oil temperature rise, a greatly decreased sliding rate, a small abrasion.
