ZqD type reducer (fork called zq type high speed ratio reducer) is based on the Zq type reducer, adding a high-speed stage to become a three-stage reducer, which expands the transmission ratio of the reducer.

　　1 type

　　1)结构型式ZQD型减速器是在尽量不改变ZQ型减速器的输入输出轴的位置和安装尺寸的前提下，增加一级传动，见图3。它共有zaD350+100、zad400+ioo、ZOD500+150、ZqD650+150、zaD850十250和ZqD1000+250六种规格。

　　2. Model

　　Markup example

　　The ZOD type reducer has a nominal center distance of 250mm, a nominal transmission ratio of 243.86 (the actual transmission is 1000), the second assembly type, the output shaft end is cylindrical, and the mark is: reducer ZOD250-XNUMX-ⅡZ

　　3 main technical parameters

　　1) Center distance The nominal center distance of the ZOD type reducer is the sum of the center distances of the middle and low speed stages.See Table 13

　　4 Overall and installation dimensions

　　The appearance and installation dimensions of the ZOD reducer are shown in Figure 3 and Table 15.

　　5 bearing capacity

　　The maximum allowable input power of ZOD reducer is shown in Table 16.
