摘要:The paper expounds the design method of tooth form when sprocket is at the condition of external enganement.The content involves the profile and its equation of externl engagement sprocket;the calcualation of coincidnce coefficient and the measures of improving it.And through a living example,the paper introduce the design process of tooth form of external engagemant sprocket concreterly.
摘要:The basic engaging equation of the Harmonic Drive is established by using the B metrix method Which is presented in the literature . The Harmonic Drive B Metrix is suitable for any wave Style. When we analysis the rigid gear tooth profiles conjugating with the spline with different gear profile, the B Metrix will not be changed.We find that there are two zones of action and two part of conjugate profiles on each side of spline tooth profile.
摘要:On the basis of the fuzzy probability design theory, Combining traditional design theory on loading capacity of the belt drives , the paper deals with the fuzzy probability design method on loading capacity of the belt drives and gives a design example.
摘要:In this paper, a “Flexible Web Gear (FWG)”whose spoke is made of rubber is presented. The noise reduction results of FWG Compared with normal gears and tooth modified gears are given.The results proved that the noise reduction effect of the FWG is the best of them . The method of structural and rigidity design of FWG is also presented in this paper.

摘要:In the paper, basic equation of finite element dynamics analysis for double circular arc gear tooth is given. The method for choosing boundary condition and distance between node points is discussed. The effect of module、 helix angle、face width、number of teeth and thickness of nave collar on proper freuqency is analyzed. we obtain follow consulation: If the point at nave collarsection is fixed and shape of elements is harmonious.the finite element method may be used in solving vibration freqency and model of double circular arc gear tooth. Main parameters effecting intrinsic attributes of geartooth is helix angle 、face width and module. The effect of nave collar and number of teeth is weak.
摘要:The induction hardening gears contact fatigue limit stress of two kinds of material were attained, and its “P S N” curues were carried out.The damage modality to teeth surface were recorded with the reversion technique of AC paper layer, and the typical damage modality of contact fatigue were analysed.
摘要:In this paper, various kinds of transversal integrated error curves wihich are displayed by computer after processing and are caused from typical technological errors in the machining of gear, are introduced. These integrated error curves can be used in fault diagnosis of technological process.
摘要:This paper thinks that the amount of related slide ratio has directive effects on the wear quantity of the low velocity gear and selecting different addendum modification coefficients, modules and addendum coefficients can change the amount of related slide ratio by the theoretic analysis of related slide ratio by the theoretic analysis of related slide ratio for gear drive and the calculation of related slide ratio for several tooth shape parameters.It presents ways of advancing gear′s wear load capacity and corective selecting the addendum modification coefficient.
摘要:This paper develops a new method for manufacturing crown gear on profiling hobbing machine, It is expected to cut out a flank which contacts with theoretic flank of crown gear on two reference points. Based on this demand the profiling plate is designed. The calculation results show that it is possible to get a flank whose symmetry is very nice, so the crown gear coupling possesses fine transfer performance.
