![]() ![]() ![]() International Conference on Industrial Engineering, ICIE 2016ģD Model of Geometrically Accurate Helical-Gear Set The examination shows a lack of interference between the gear and the wheel, side clearance satisfies mating H, E, tolerance h, which corresponds to the highest class of accuracy, specified by a state standard GOST 1643-81 for the helical-gear set. The accuracy of a gear model is analyzed by clearance measuring, interference, parameters of rims, and sizing of contact patterns. ![]() The teeth are matched with gashes by using a pitch point and cutting the teeth by a plane which is perpendicular to a transmission axis. The gear assembly is carried out with the help of a layout sketch. Then the tooth is distributed following the Circular Sketch Pattern along a blank, forming a rim of the wheel. The closed region of a tooth contour is pressed out along the trajectory, a helix with an angle of lead equal to the helix angle is used in such capacity. The involute meshing is formed in the normal as related to a tooth curve plane using equivalent wheels and making involutes according to parametric equations. The construction stages are calculation, development of blanks, development of tooth rims and involute gears. KhmarovaĪ production technology for a geometrically accurate Solid model of a helical-gear set in the SolidWorks package is suggested.
