Abstract


Spiral bevel gear is to achieve the intersecting axis motion passed basic components , with a large degree of coincidence , high carrying capacity , high transmission efficiency , smooth transmission , low noise , etc. , are widely used in automobiles, aircraft , machine tools , and a variety of mechanical products . spiral bevel gear finishing by lapping . Lapping is not only able to play the role of pre - run together , reducing the toothed and the tooth pitch error , and can be canceled to a certain extent the deformation after heat treatment ; the lapping a Hardened processing technology , it is removed by a grinding method trace of the machining allowance of the gear surface , thus effectively improving the gear surface finish as well as to improve the contact condition of the gear ; Furthermore, the lapping technique or recognized the realization of the bevel gear to reduce one of the best means of the noise . This paper focuses on the spiral bevel gear grinding mechanism , and made some of the lapping process improvements . The main research content and research results are as follows : 1 . Lapping cutting mechanism and lapping processing space model into a simple model of the plane , and on this basis , analysis of the cutting forces and abrasive lapping the maximum depth of cut . 2 CNC spiral bevel gear grind teeth machine used the V / H Adjustment Act lapping movement model and from the TCA 's point of view to analyze the relationship between V / H adjustment with the tooth surface contact area of the mobile trend as well as gear lapping when teeth face-to-face backlash automatic control theory . Using the machine geometry motion error lapping processing , combined ETCA thought proposed V / H to adjust the value of the improved algorithm . Of gear tooth surface the grinding rate as well as the grinding of the tooth surface boundary and as a basis for guidance lapping processing parameters set . 5. Lapping trajectory control technology and fixed-point grinding technology , based on ETCA thinking lapping technology Gleason600HTL CNC grind teeth machine carried lapping experiment and based on TCA thinking lapping technology conducted contrast , experimental result shows that : ETCA lapping technology proposed in this paper based on entirely practical and feasible , and can play a certain role in promoting improvements on the improvement effect lapping and lapping process .
