双曲率

The double circular arc spiral bevel gearing is a type of points contact transmission by concave-convex tooth profile between meshing gearing, it has the advantages of large comprehension radius of curvature, good lubricating ability etc..

双圆弧弧齿锥齿轮传动是一种凸凹齿廓相接触的点啮合传动，有较大的综合曲率半径，因此有很高的接触强度；且润滑效果良好。

Structure form adopts converse triangle beam double-hole connection welded by general electric trolley wall plate and steel plate, connection shaft, triangle beam bottom is connected with girder by nut and thrust bearing, triangle beam could rotate 360 degrees horizontally, thus realize whole set electric trolley horizontal rotation, largely reduce curve track curvature radius of electric hoist traveling mechanism.

结构形式采取通用电动小车墙板与一个钢板和连接轴组焊的倒三角形吊梁双孔连接，三角吊梁下面通过螺母及推力轴承与一个横梁连接，三角吊梁相对横梁可在水平方向做360度旋转，从而实现电动小车的整体水平方向转动，大大减小了电动葫芦运行机构弧形轨道曲率半径。

With the use of RNG turbulent model in the CFD software Fluent, the inner flow of double suction centrifugal pump with semi-spiral suction chamber was calculated.

在CFD软件Fluent中采用考虑了旋转与曲率影响的RNG湍流模型，对具有半螺旋形吸水室的单级双吸离心泵进行了全流道数值模拟计算。
