结构简介
* 防护等级 IP44
* 机座、端盖和轴承盖
电动机一般只有一个圆柱形轴伸；根据用户要求，B3及B35型的电动机可制成两个轴伸。第二轴伸仅能用联轴器传递额定功率。转轴材料采用45号优质钢（GB/T699）。 * 接线盒
从主轴伸端视之，电动机的接线盒位于机座右侧。若接线盒要装在左侧，则必须在订货时加以说明。接线盒内有六个接线柱，接线盒盖内有接线图，接线标志全部符合IEC60034-8的规定。两个相邻导电零件的间隙不小于8毫米；所有漏电距离不小于12毫米。接线盒内另有一个供接地用的接线柱。 * 轴承
本系列电动机用的轴承型号和规格见表1
Construction
* Protection IP44
* frame, endshield and bearing cap
All made of Grey cast ironHT200 (GB/T9437) and the outer surface of the frame is provided with longitudinal cooling ribs to increase cooling effects. * Shaft extension
Standard motors have a cylindrical shaftextension. Motors of B3 and B35 type with two shaft extensions are afforded onrequest, but the second shaft extension can only transmit rated output withdirect coupling. The shaft is made of high grade steel No 45 (GB/T699). *Terminal Box
The terminal box is arranged at the“right hand side” when looking at the driving end. If the terminal box is to bearranged at the left-hand side, this fact must be specifically stated whenplacing the order.
Six terminal studs are provided in theterminal box and a connecting diagram is shown on the back of the cover.Terminal markings used are in full conformity with IEC publication34-8.Clearance between two neighboring conducting parts is made not less than8mm and all creepages not less than 12mm. An extraterminal is provided inside the box for grounding purpose. * Bearing
The type and size of bearings used inthese motors are given in table 1
