Research of principle distortion of helical gear tooth surfaces during the grinding processing by worm-wheel machining and modification based on the tooth three section parameters
Based on the principal distortion issue of helical gear tooth surfaces during the grinding processing by worm-wheel ma-chining,the contact trace equation was deduced,the evaluation scope of gear tooth profile and lead was selecteel and the distor-tion model was created,the deviation values of tooth profile and lead angles were calculated.The distortion optimization parame-ters also included the tooth profile drum and the counterpart gear tooth drum or the distortion.Through the experiment and verifi-cation,the distortion compensate methods could effectively optimize the distortion,load bearing capacity,the gear meshing impact force,the gear precision and vibration or noise level.
