RV Key Part of Cycloid Cam Planetary Speed Reducer profile modification methods.
Background technology
RV decelerators are a kind of little gear difference planetary driving mechanisms of secondary seal formula.With small volume, lightweight, carrying energy
Power is strong, gearratio is big, long lifespan, high precision the advantages of, obtained at present in the precision drive such as industrial robot field extensively should
With.
Cycloidal pinion engaged pair is the core component of RV decelerators.Theoretic conjugate profiles does not have radial clearance, in order to
Ensure the compensation of smooth-going, the formation of lubricating oil film, convenient disassembly and the foozle of engagement, all can be in cycloid gear and pin tooth
Between design certain gap, so, the cycloid gear in actual use is all cycloid gear after correction of the flank shape, theory pendulum
Line flank profil cannot directly apply to production.
At home in current production practices, although the correction of the flank shape of cycloid gear generally uses modification of equidistance method, modification of moved distance
The combination of method, modification of rotated angle method these three traditional correction methods.Document [1] is detailed using biography using RV320 decelerators as example
The optimal amount of practicing Buddhism or Taoism that correction method of uniting carries out correction of the flank shape to Cycloidal Wheel solves method.Go deep into to cycloid gear Meshing Pair research
With the continuous improvement required its transmission accuracy, some more efficient correction methods also continuously emerge.Existing Chinese registered patent
No. 201310736325.1 " determination of cycloidal gear of gerotor motor scope and modification curve ", the patent proposes one kind with
It is constraints that uniform radial clearance, radius of curvature, which are seamlessly transitted etc., and it is object function to improve volumetric efficiency and mechanical efficiency
Modification curve determines method.Existing No. 201310521427.1 " profile correction of the flank shape of cycloidal gear of cycloid motor of state's registered patent
Method ", the patent proposes only to carry out according to theoretical correction of the flank shape function to being located at the region between tooth top and tooth root on Cycloid tooth profile
Correction of the flank shape in the case where ensuring the gas of Cycloidal Wheel and the smooth engagement of stator, can effectively improve volumetric efficiency, the machine of cycloid hydraulic motor
The performance parameter such as tool efficiency and pressure rating.But these correction methods are not all accounted for when cycloidal pinion engaged pair is driven
Stress and deformation, particularly in the application of RV decelerators in high-load situations, this, stress and deformation when cycloidal pinion engaged pair is driven
The steady and transmission accuracy of transmission will be had a strong impact on.
