免鍵(jian)高扭矩同步帶輪(lun)(lun)P8M型由輪(lun)(lun)緣、輪(lun)(lun)輻和(he)輪(lun)(lun)轂三部分組成。設計帶輪(lun)(lun)時(shi)，應使其結構便于制造，質量分布均勻，重量輕，并避免由于鑄造產(chan)生(sheng)過大的內應力。

當(dang)(dang)V>5m/s時進(jin)行(xing)靜平衡，當(dang)(dang)v > 25m/s時進(jin)行(xing)動平衡。同步帶(dai)輪材(cai)料中常用(yong)(yong)(yong)灰鑄鐵、45#鋼、鋁(lv)合金、銅(tong)或(huo)工(gong)程(cheng)塑料。灰鑄鐵應(ying)用(yong)(yong)(yong)廣(guang)泛，當(dang)(dang)V≤30m/s，V ≥ 25 ~ 45m/s時使用(yong)(yong)(yong)HT200。則宜選用(yong)(yong)(yong)創造生鐵開鑄鋼件(jian)，也(ye)能用(yong)(yong)(yong)厚鋼板沖(chong)壓模具一(yi)電焊焊接(jie)同步帶(dai)輪。小(xiao)輸出功率(lv)傳動系統能夠用(yong)(yong)(yong)鋁(lv)鑄和(he)塑膠。
