Title:
DESIGN METHOD BASED ON ACTUAL LOAD FOR TOOTH SURFACE CONTACT SPOT OF GEAR
Document Type and Number:
WIPO Patent Application WO/2020/252842
Kind Code:
A1
Abstract:
Disclosed by the present invention is a design method based on actual load for a tooth surface contact spot of gear, comprising the following steps: step 1: determining a 3D model of a pair of straight tooth bevel gears; step 2: determining a contact spot under a near zero load and a contact spot under a rated load, and using the contact spot as a theoretical design spot; step 3: comparing the theoretical design spot obtained in step 2 to the contact spot under the rated load to obtain the deviation therebetween; step 4: obtaining a new amended contact spot; step 5: comparing the contact spot obtained in step 4 to the theoretical design spot obtained in step 2 so as to obtain an amended gear contact spot; step 6: according to the new model deviation, repeating step 5 until a suitable contact spot is obtained; the design method based on actual load for the tooth surface contact spot of a gear, is capable of eliminating the influence of elastic deformation on the contact spot to optimize the contact spot in the design stage, thereby improving the service life of a gear pair.
