三角皮带正常磨损是普遍现象,但是磨损得太快,就很值得研究。皮带坏了不但误事,还得花钱。那么,怎样才能使三角皮带磨损得慢些呢? 1.皮带轮槽角α_1应与皮带两边夹角α相吻合。由图1可知,皮带两边夹角α为40°,所以α_1应为34°～38°,具体角度视皮带轮大小、皮带型号不同而异。因此,加工或新购皮带轮时应注意确保α_1<α,而皮带轮糟顶宽b_0应大于或等于皮带顶 V-belt normal wear is a common phenomenon, but wear too fast, it is worth studying. Bad belt not only misconduct, have to spend money. So, how to make the V-belt wear more slowly? 1 pulley slot angle α_1 should be consistent with the angle between the belt α. As can be seen from Figure 1, the angle α between both sides of the belt is 40 °, so α_1 should be 34 ° ~ 38 °. The specific angle depends on the pulley size and the belt model. Therefore, the processing or purchase of new pulley should pay attention to ensure that α_1 <α, while the pulley top width b_0 should be greater than or equal to the top of the belt
