一、概述电机轴伸长度是电机主要外形尺寸之一。通常控制圆柱形轴伸长度较为简易,但在圆锥形轴伸长度的加工及测量方面却有一定的困难。国标GB757-79《电机圆锥形轴伸》中对圆锥形轴伸作了规定,见图1。尺寸E的偏差应符合GB756-79《电机圆柱形轴伸》的规定。在表1中摘录了圆锥形轴伸全部规格,列出了E和E_1的公称尺寸及偏差值,并在表2中列出E_1偏差δ及D_2偏差h8。
First, an overview Motor shaft elongation is one of the main dimensions of the motor. Usually control the cylindrical shaft elongation is relatively simple, but in the conical shaft length of the processing and measurement have some difficulties. National standard GB757-79 “motor conical shaft extension” in the conical shaft extension made the provisions shown in Figure 1. Deviation of size E should be consistent with GB756-79 “cylindrical motor shaft extension” requirement. Table 1 summarizes all conical shaft extension specifications, lists the nominal dimensions and offset values for E and E_1, and lists E_1 deviations δ and D_2 deviations h8 in Table 2.
