The car drive belt drive all parts of the activities, it's broken car is not move. Because mobilization machine through the belt drive drive all kinds of help institutions run, some tightening machine, power steering pump, air conditioner exchange generator, etc. , if the belt breaks, may present the skid, will make coherence with the help of the agency lost effectiveness, or reduce its performance, thus affect the normal use of car. Thus, the current is necessary to check the drive belt. Belt of view the way is very complicated. First check the belt tension, choices in zui long did not handle the drive belt span two thumb excessive pressure, if the quantity of the belt at about 12 mm, then think of belt tension is just right. If the belt tension is too large, perhaps say too loose, can form a sliding gear, transmission is not complete. And belt adjust too tightly, it will make the belt tensile deformation, and at the same time, also will decelerate belt pulley and the bearing wear. Therefore, should be the relief of the coherent nuts or bolts loosen, adjust the belt tension to zui condition. The double-sided rubber synchronous belt knowledge, you can reference Uliflex drive website content for understanding and learning or log on to http://www. lilainuo。 Com, regularly updated information content let everybody timely grasp industry trends, welcome the attention.
