Abstract

The invention relates to the technical field of gear transmission, in particular to a sectional type dot-line engagement gear pair which comprises a bevel gear A and a bevel gear B. A gear outline curve of the bevel gear A comprises a convex circular arc curve section A1, a short transition curve section A2 and an involute curve section A3. The upper end and the lower end of the short transition curve section A2 are in smooth transition connection with the lower end of the convex circular arc curve section A1 and the upper end of the involute curve section A3 correspondingly. The gear outlinecurve of the bevel gear B comprises an involute curve section B1, a short transition curve section B2 and a concave para curve section B3. The upper end and the lower end of the short transition curvesection B2 are in smooth transition connection with the lower end of the involute curve section B1 and the upper end of the concave para curve section B3. The convex circular arc curve section A1 andthe concave para curve section B3 form double-dot contact. The involute curve section A3 and the involute curve section B1 form line contact. According to the engagement gear pair, in the engagementprocess, the dot contact form exists, the line contact form also exists, and the gear pair has the characteristics of being high in bearing ability, low in vibration noise, long in service life, and stable in transmission.

Description

technical field [0001] The invention relates to the technical field of gear transmission, in particular to a segmented point-line meshing gear pair. Background technique [0002] Involute gears and circular arc gears are widely used because of their line contact and point contact meshing characteristics respectively; currently, many technicians in the field start from the basic principles of gears, design modification, analysis process and manufacturing technology. A lot of beneficial research has been done to meet the performance requirements of mechanical equipment for transmission systems such as high speed, heavy load, high reliability, long life, and low noise. [0003] Patent 201410309538.0 proposes a design method for point-contact double parabolic gears. The basic tooth profile is formed by using two parabolic segments plus a transition curve. The designed point-contact double-parabolic gear transmission is separable. When there is a center distance error, no It wil...
