The gear drive is the most basic mechanical transmission drive mode, plays a very important role in industrial development. Therefore, the requirement with gear large carrying capacity, high precision, long life and low noise transmission have a breakthrough. And drum the unique advantages of gear to meet those needs, the drum of the gear processing is of great significance.Drum gear has many special advantages, in view of the drum of the shape of the tooth in a way to present direction tooth shape drum, the tooth profile on the shape of the involute similar to characteristics, and study the drum drum quantity size and quantity distribution of processing drum is the necessary premise of teeth. Through the internal meshing top gear processing of that internal meshing honing tooth use remove method of interference can accurately honing the drum teeth, and further analyzes internal meshing honing the teeth out of the drum making quantity, for making in the form of a drum gear tooth processing qualitative and quantitative analysis of laid a foundation.Contents as follows:(1) Introduces the principle and features of the making process, and internal and external honing the comparative analysis in processing drum that honing as the best choice method of gear.(2) Internal meshing honing principle is analyzed, and the research of internal meshing helical gear interference characteristic, establishes the removal of the tooth surface equation after intervention, and the tooth profile to and concluded that the honing in a drum tooth can be honing the theory, the feasibility of this method proved theory. Analysis shows that the tooth in overlapping coefficient is close to making in2, tooth profile relative sliding speed change small.(3) Based on UG internally honing wheel and be processing straight gear accurately parameterized modeling. Will the number for97in gear wheel and honing for19straight gear as the research object, and then set up two other spiral Angle different inside honing wheel, still and19top gear assembly straight teeth. The working condition and fit with the cross shaft assembly, and to the assembly for the interference.(4) Use of the model is simulated processing, remove interference quantity got be processing gear shape. The gear of extremely different radius, different flat end in the tooth profile within plane measured the arc length, then calculates drum quantity.(5) In the above gear drum quantity computation, and on the basis of the axial and unprocessed arc length when comparing calculated, along the axial drum of quantity and distribution change trend, and a data form rendering the drum quantity change trend chart.(6) In other conditions remain unchanged, the transformation of the spiral Angle within different wheel honing, analyzes its spiral Angle on processing drum the influence of the amount, and concludes that the spiral Angle and drum amount of relationship.The results of the study show that:(1) Internal meshing honing the interference phenomenon with teeth, and its interference is part of larger ends small; In removing interference, and was gears up into gear in the form of a drum, in the tooth profile at both ends on a thin body shape.(2) Spiral angle changes led to shaft angle changes, drum-shaped size and shaft angle has the very big relations, shaft angle is the smaller drum shape.(3) In honing smaller portions of the quantity, tooth profile shapes approximate to involute, honing the large quantities of involute is no longer.
