NMRW减速机本身可以组合成一个双级联体减速机。DRW的传动比即为NMRW和二级NMRW传动比的乘积,可将传动比拓展至1:300--3200的范围。

DRW并不是两个NMRW的简单组合,合理的组合应使两个减速机达到一致的工况,因此二级减速机的机座规格要大于减速机的机座规格。
中研紫光减速机结构特点:
1.铝合金铸造箱体,适应的万neng安装配置
2.充分的冷却筋条,使机体具有优良的热传导性能;
3.从025--150共10种机座规格;传递功率范围从60W--15KW;
4.速比范围大,每单个机座具有从5:1到100:1的12种减速比;
5.精密磨削加工的硬齿面传动蜗杆,效率高、输出扭距大;
6.低噪声平稳运转,能适合在恶劣的环境中长期连续工作;
7.重量轻,机械强度高;
8.模块化组合使PCRW及DRW将RW减速机的传动比拓展到:i=5--32000.
9.外壳:铝合金(机座:025--090),铸铁(机座:110--150);
10.蜗杆:20Cr钢,碳、氮共渗处理(精磨后保持齿面硬度HRC60,硬层厚度>0.5mm);
11.蜗轮:特殊配制的耐磨镍青铜。
12.涂漆
--铝合金:
①抛丸处理后,特种防腐处理(保持银白合金色感,并耐汽油、二甲苯等有机溶剂的腐蚀);
②磷化处理后,喷涂RAL5010兰色烘烤漆;
--铸铁:喷涂RAL5010兰色烘烤漆。
13.效率
效率是减速机的重要指标,取决于蜗杆蜗轮传动副的设计制造以及磨擦状况。由于减速机在运转状态下和在静止状态下具有不同的磨擦特性,因此减速机的效率相应有动态效率及静态效率:
①动态效率ηd:减速机在运转工况(动磨擦)下的传递效率;
②静态效率ηS:减速机在停止状态(静磨擦)下的传递效率;
由于磨擦副的静磨擦系数大于动磨擦系数,因此减速机的动态效率大于静态效率,即ηd>ηS。
14.传动可逆性
在减速机输出端(蜗轮)施加力矩带动输入端(蜗杆)的传递过程即为减速机的逆向传动。减速机在逆向传动时所表现的特性即为蜗杆减速机的传动可逆性。在使用过程中必须关注选定减速机的这种特性。
减速机的传动可逆性与减速的效率有关,对应于静态效率ηS及动态效率ηd。将减速机的传的传动可逆特性描述如下:
ηS<0.5:静力不可逆。即减速机在静止状态时,不能通过向输出蜗轮施加力矩带动输入蜗杆,逆向传动自锁。
ηS=0.5-0.55:低静力可逆。即减速机在静止状态时,可以通过向输出蜗轮施加力矩带动输入蜗杆,自锁性不强。
ηS>0.5:静力可逆。即减速机在静止状态时,可以通过向输出蜗轮施加力矩带动输入蜗杆,不能自锁。
ηd<0.5:动力不可逆。即减速机在传动过程中,输入轴脱开动力时,输出轴即能立即停止。
ηd<0.5-0.6:低动力可逆。即减速机在传动过程中,输入轴脱开动力时,输出轴不能立即可靠停止。
ηd>0.6:动力可逆。即减速机在传动过程中。输入轴脱开动力时,输出轴不能自锁停止。
