一、βx的确定 设理论测点在分度圆上,计算时以分度圆给定的螺旋角作为依据。斜齿圆柱齿轮齿型在分度圆上的一点,按齿向方向绕分度圆柱运动的轨迹AS(或叫齿线)实为圆柱螺旋线(见图1),其参数方程:式中:β1-分度圆柱的螺旋角;α-分度圆半径;t-测点投影在xy平面与x轴的夹角。 因测 First, determine the set of βx The theoretical point of measurement in the sub-degree circle, the calculation of the pitch angle given by the helix as a basis. Helical cylindrical gear tooth type point on the sub-degree circle, according to the direction of the tooth around the graduation cylinder movement trajectory AS (or called tooth line) is actually a cylindrical helix (see Figure 1), the parameter equation: Where: β1-indexing cylinder helix angle; α-indexing circle radius; t-measuring point projection in the xy plane and the x-axis angle.
