What are the basic structure and working principle of tow tractor?
Function is to avoid a thin section and complicated section profile die after twisting, bending, wave and other defects, and multimode products are friction and winding, occurrence of different lengths of the phenomenon.
The utility model has the advantages of wide application range and convenient operation. The tractor is a kind of extrusion auxiliary equipment, which guides the extrusion products to advance along the guide rail at a constant speed, ensures the straightness of the products, and improves the yield and efficiency of the products.
Trailer traction machine principle and DC motor is same, but there are special working conditions: space size by gauge and wheel diameter limit; in the locomotive running through the rail and turnout to withstand considerable impact vibration; large and small gear meshing when the armature will produce strong torsional vibration in use; in the harsh environment, rain, snow, dust and other easy to invade. Therefore, in the east of the design and structure of tractor motor also has many requirements, such as to make full use of the inner space of the compact structure, the insulating materials and magnetic materials with higher grade, the parts necessary mechanical strength and high stiffness, the whole machine must have good ventilation and heat dissipation conditions and dust proof ability, to take special measures to deal with the difficult conditions of "reversing" to reduce carbon brush spark etc..
