gearsInMesh Create gearsInMesh object. The object is handle class object. Syntax gearsInMesh(g1,g2) Description gearsInMesh(g1,g2) create gearInMesh object with gears g1 and g2 in mesh Input arguments g1, g2 - gear object. Module of the gears must be equal Properties G1, G2 - gear objects a - center distance alphaw - working (operating) pressure angle Object functions plot draw gears in mesh Syntax plot(GM) draw gears GM.G1 and GM.G2 in mesh plot(__,'-th1',th1) specify initial rotation angle th1 of the first gear GM.G1. plot(__,'-zoom',fac) specify zoom factor fac in units of module. plot(__,'-a',a) specify center distance a plot(__,'-np',np) specify number of points for gears contour Input arguments GM - gearsInMesh object Optional input arguments 'save' - save figure to jpg file Optional name-value input arguments '-a',a - center distance. Default value is a = GM.a '-np',np - number of points used to approximate gear profile. Defult value is 20. '-th1',th1 - initial rotation angle in degrees of gear g1. Default value is 0. '-zoom',fac - zoom factor in units of module. E.g. if fac=3 the display window is (-3m+g1.R,3m+g1.R,-3m,3m) where m is module and g1.R radius of gear 1 pitch circle. Default value is no zoom animate draw succesive positions of gears in mesh Syntax animate(GM) animate gears GM.G1 and GM.G2 in mesh animate(__,'-dth1',dth1) specify step of rotation angle dth1 of the first gear GM.G1. animate(__,'-zoom',fac) specify zoom factor fac in units of module. animate(__,'-a',a) specify center distance a animate(__,'-np',np) specify number of points for gears contour animate(__,'-nr',nr) specify number of turns of gear 1 Input arguments GM - gearsInMesh object Optional input arguments 'save' - create avi movie Optional name-value input arguments '-a',a - center distance. Default value is GM.a '-nr',nr - number of rotation of gear 1. Default value is 1. '-np',np - number of points used to approximate gear profile. Defult value is 20. '-dth1',dth1 - step of rotation angle in degrees of gear MG.G1. Default value is 0.5 degrees. '-zoom',fac - zoom factor in units of module. E.g. if fac=3 the display window is (-3m+MG.G1.R,3m+MG.G1.R,-3m,3m) where m is module and MG.G1.R radius of gear 1 pitch circle. Default value is no zoom Examples % the examples will work only with draw19 library addpath('..\draw2d') Example1 % define gear rack with module 1mm a = gearRack(1); % define 9-tooth and 9-tooth gears G1 = gear(a,5);
