Summary: To 2M546/4A (9B) model principle of double-faced muller motion undertakes vertical analysis, knowable and abrade dish of generation umbrella shape be out of shape is as a result of You Xing rotate rotation moves on, next grinding on millstones, predestined relationship of inside and outside fashions different opposite grinding career and cause. Accordingly, muller is not changing tine to encircle the premise of rotate speed, exchange the rotate speed of sun gear, acquire bulk of You Xing annulus thereby the speed of two kinds of rotation with equal, opposite way, can eliminate umbrella shape to be out of shape. Keyword: Double-faced muller, athletic principle, umbrella shape is out of shape, technical measure, abrade dish of 1 introductive 2M5464/4A (9B) model vertical double-faced muller basically uses Yu Shiying crystal piece, silicon, germanium piece, annulus of ceramics of glass, contented, piston, a powerful person piece, horological glass, lead, iron, boron, molybdenum piece, . The accurate treatment of ideal plane is the one catastrophe problem of machining, as the ceaseless development of science and technology, especially the development of accurate and mechanical industry, the planar treatment of dependability, efficient, high accuracy appears highlight particularly; Besides adds workpiece in grinding when, grind millstones is changing along with grinding loss at the same time, because how this maintains,grind the precision of millstones is inside the limits of our place demand, became the crucial issue that makes sure ideal plane is machined. 2 motion principle should assure to grind the flatness of millstones, the key depends on how be being eliminated grind the umbrella record that millstones produces in grinding process is out of shape, should find out above all cause cause of umbrella shape metabolic. Graph L is 2M5464/4A (GB) model grind the rate plan of millstones. (1) the speed clockwise that millstones grinds to fall with N below hypothesis rotates, the speed anticlockwise direction that millstones grinds to go up with N on rotates, they are in graph 1 on grind the linear velocity of the predestined relationship outside millstones falls for V, on V. (2) the revolution speed of You Xing annulus is N. , with next grinding millstones is the same as to. (3) the opposite rotation speed of You Xing annulus is NH, with next grinding millstones is retrorse, and with on grind millstones is the same as to. From the graph 1 knowable, the brim outside millstones grinding to stand by below, the grinding motion speed of opposite workpiece because with N2 of speed of rotation of You Xing annulus is retrorse and increase relative to grinding speed along with workpiece; Contrary, stand by inside the opposite grinding speed of the predestined relationship is reduced, grinding speed is increased place, grind the grinding quantity of millstones is increased, millstones grinds to will form convex umbrella shape to be out of shape under place; Go up conversely grind because predestined relationship of millstones inside and outside is opposite inside grinding speed big outside small, reason forms shape of sunken form umbrella to be out of shape. Manage together, when N2 makes a clockwise turn, millstones grinds to will form sunken deformation body below, and on grind millstones forms convex umbrella shape to be out of shape. 3 data analyse us to fasten a principle from week runner about annulus the random in the department the velocity relationship between H of two rounds of lever that reach a department is knowable, driven circumgyrate direction and speed volume, decide the configuration at the orgnaization not only, and angular velocity of number, as active as each rounds tine member is concerned. The angular velocity that week runner is each component concerns under existence: Gh of the ω in type of H of ω of G - of ω Gh= ω is the relative speed of component part H, ω G is component part effective rate, ω H is communal angular velocity. By the graph 2 knowable: 2 photographs of ω H of ω of = ω 2- , namely runner of week of basis of N2-nh of N2 photograph ＝ fastens character, alternate its age number reachs what active member speed can realize N2 to change to, now 2M5464/4A (9B) model round of department motion computation of double-faced muller as follows: Ring gear of Z2=108 of number of teeth of a cogwheel of You Xing of Z1=99 of number of sun teeth of a cogwheel ages several Z3=315 to simplify orgnaization, we change the rate of driving link sun gear only only. Will realize the way of N2 of rotation of You Xing annulus. (1) when Nl0=0. 4373 (R ／ S) , compare computation according to transmission system drive: From above motion deserves to compare computation, we realized N2= ± 0.
The purpose of 07. 4 conclusion are analysed by above knowable, grind the umbrella shape of millstones is out of shape, be go up as a result of what You Xing rotate moves from have a change of luck, next grinding on millstones, predestined relationship of inside and outside fashions different opposite grinding career and cause, should try to alternate only that is to say You Xing annulus is opposite the direction of rotation of rotation, reasonable deserve to compare rate, can overcome abrade malpractice of dish of metabolic of shape of easy generation umbrella. 2M5464/4A (GB) model below the premise that muller is not changing tine to encircle rotate speed, because exchanged the rotate speed of sun gear, acquire bulk of You Xing annulus thereby the speed of two kinds of rotation with equal, opposite way, achieved eliminate goal of umbrella shape metabolic.
