DESIGN AND TEST RESULTS FOR MULTIPLE-CONTACT GEAR OF «BELARUS»-TRACTOR TRANSMISSION

Abstract

Gearing with high contact ratio (HCR) has other properties than gearing formed with a standard original profile. The gearing is characterized by increased loading capacity. The paper presents a boundary element method (BEM) which is applied to solve a problem pertaining to stress concentration at the tooth root. Gear-box casing with multiple-contact gear has remained in series production. Results of the investigations have been realized in the experimental gearbox of the «Belarus-1523» tractor.
