摘要:The instantaneous contact zone and contact stress distribution are analyzed by boundary element compliance matrix method.It is the basis of calculating the load distribution between teeth,bending and contact strength,and also provides the theoritical foundation for studying the effect of running in and modification on meshing properties.
摘要:The paper develops the traditional method of the fault modes and effects analysis by introducing the fuzzy set theory,presents the fuzzy judgement model and discusses carefully the approach and procedure by taking a tank for example.The results can provide the important theory guide for improving the quality and the system reliability of the machine and making up maintenance plannings reasonably.
摘要:In this paper,further analysis and derivation of the complicated relationship between the belt tension effected by the belt centrifugal force and the belt speed have been mode.The belt tension caluclation method is obtained to supply some necessary data for related formulas.This method is useable for some parts design of high speed belt drive and related devices.
摘要:From structure designing and adopting the GDZ driving axle and CBN grinding wheel,the first cone enveloping twice worm drive device is developed.The device has been tested and has the performance of high efficiency and high load capacity.A new field is opened up in worm transmission with multi start and small contact ratio.
摘要:A mathematics analytic model of a motor in wheel transmission system is set up by using the finite element theory.The tooth force of the helical gear on load in the transmission is analyzed.By means of wireless telemetering the dynamic tooth stress of a developed motor in wheel transmission is tested.The study shows the law of the root stress changing in various speed.The optimum speed,the transmission speed with the hightest mechnical efficiency,is obtained.And based on the test results,a rational method to improve the processing technology of a motor in wheel system is presented.
摘要:The tooth end relief is an effective process for double circular arc gear to lighten the shock,lower the meshing noise,and prevent the tooth end from breakage,so as to prolong the service life.For this purpose,the paper presents a practical calculation method and its industrial applications of tooth end relief for double circular arc gear according to the researches of the project 86J5103 and the reference
摘要:In the worm driving,a series of temperature values of typical points in the vicinity of a worm wheel tooth surface were gained by means of thermocouple under the conditions of different torques.The distribution feature and the fluctuation tendency of the temperature in the vicinity of the worm wheel tooth surface were investigated and analyzed.
摘要:The tooth curve of a plunge shaving cutter for an external gear is a recess transcendental curve,so it is difficult to grind it.This paper presents the method for sharpening flanks of the plunge shaving cutter by modifying a grinding wheel in a general grinding machine,optimizes the sharpening parameters and lays the foundation for the production and application of the plunge shaving cutter.
摘要:This paper introduces the method of forming teeth’s section form of cycloid sprocket hobbing cutter according to the tooth profile normal method,and the cutter design result verified through simulative manufacturing.
摘要:In this paper,the cutting method of the bevel gears with Klingelnberg cyclo palloid system and Oerlicon method on machine SKM2 are analyzed.Based on the theory of conjugete gear tooth action,a new exact method on machine setting calculating for generating cyclo palloid bevel gears is presented.
