免鍵高扭矩(ju)同步帶(dai)輪(lun)(lun)S8M型由輪(lun)(lun)緣(yuan)、輪(lun)(lun)輻(fu)和輪(lun)(lun)轂三(san)部(bu)分(fen)組成(cheng)。設(she)計帶(dai)輪(lun)(lun)時，應使(shi)其結構便于(yu)制造，質量分(fen)布均(jun)勻，重量輕(qing)，并(bing)避免由于(yu)鑄造產生過大的內(nei)應力。

當V>5m/s時(shi)進行(xing)(xing)靜平(ping)衡，當v > 25m/s時(shi)進行(xing)(xing)動平(ping)衡。同(tong)步(bu)帶輪(lun)材料(liao)中(zhong)常用(yong)(yong)(yong)灰(hui)鑄鐵、45#鋼、鋁(lv)合(he)金(jin)、銅或工(gong)程塑料(liao)。灰(hui)鑄鐵應用(yong)(yong)(yong)廣(guang)泛，當V≤30m/s，V ≥ 25 ~ 45m/s時(shi)使用(yong)(yong)(yong)HT200。則宜選用(yong)(yong)(yong)創造生(sheng)鐵開鑄鋼件，也能(neng)用(yong)(yong)(yong)厚鋼板沖壓模具一電焊焊接同(tong)步(bu)帶輪(lun)。小輸出功(gong)率傳動系統能(neng)夠(gou)用(yong)(yong)(yong)鋁(lv)鑄和塑膠(jiao)。
