Simple Calibration of Three-Axis Accelerometers with Freely Rotating Vertical Bench by Federico Pedersini

“…To keep the setup as simple as possible, the necessary prior knowledge about the geometry and the motion of the bench has been minimized: the only required constraint is the verticality of the rotation plane, which can be simply achieved in practice by means of a level tool. No prior knowledge is required about the bench rotation, as the calibration procedure estimates both the accelerometer parameters and the bench motion. …”

相切式四圆弧齿轮基本齿廓设计 by 刘梓林, 段建中

“…The design of basic rack tooth profile of tangent quadruple circular-arc gear means to the problem that non-working surface of tangent double-arc gear contact is proposed.Moreover,the tangent quadruple circular-arc gear has one simultaneous meshing point more than double-arc gear.Based on the geometrical analysis of the design,the parameters of basic rack tooth profile of tangent quadruple-arc gear are calculated.Then,the way to calculate the gap of the non-working surface of tangent calculate double-arc gear or of tangent quadruple circular-arc gear and the criterion whether non-working surface contacts are proposed and proven.Without cusp,the design of basic rack tooth profile of tangent quadruple circular-arc gear adapt to being processed by CNC gear form grinding tool.…”

长锥距弧齿锥齿轮的加工参数设计与加工试验 by 张华, 徐增军, 朱云振, 雷宝珍

“…For its cone distance dimension is very large,long-cone-distance spiral bevel gear is milled on the large scale special purpose machine tool generally,and the process is difficult to realize.Using pre-control technique of the tooth contact bearings,the gear machining parameters are designed,the precision gear 3D model is established,and the contact situation between the mesh surfaces is simulated.Based on the horizontal machining center,the NC program codes are compiled to experiment machining process of the long-cone-distance spiral bevel gear.The experiment results show that the long-cone-distance spiral bevel gear could be machined on horizontal machining center.…”
