帶擋(dang)邊齒形(xing)惰輪S2M、S3M、HTD3M型(xing)由輪緣、輪輻和(he)輪轂三部分(fen)組成。設計帶輪時(shi)，應(ying)使其結構便(bian)于制(zhi)造(zao)，質量(liang)分(fen)布均勻，重量(liang)輕，并避免由于鑄(zhu)造(zao)產生過大的(de)內應(ying)力(li)。

當(dang)(dang)V>5m/s時進(jin)行(xing)靜(jing)平(ping)(ping)衡，當(dang)(dang)v > 25m/s時進(jin)行(xing)動平(ping)(ping)衡。同(tong)步(bu)帶輪(lun)材料中(zhong)常用(yong)(yong)(yong)(yong)灰(hui)鑄鐵(tie)(tie)、45#鋼、鋁合金、銅或工(gong)程塑料。灰(hui)鑄鐵(tie)(tie)應用(yong)(yong)(yong)(yong)廣(guang)泛(fan)，當(dang)(dang)V≤30m/s，V ≥ 25 ~ 45m/s時使用(yong)(yong)(yong)(yong)HT200。則(ze)宜選用(yong)(yong)(yong)(yong)創造(zao)生鐵(tie)(tie)開鑄鋼件，也能(neng)用(yong)(yong)(yong)(yong)厚鋼板沖壓模(mo)具一電焊焊接同(tong)步(bu)帶輪(lun)。小(xiao)輸出功率(lv)傳動系統能(neng)夠用(yong)(yong)(yong)(yong)鋁鑄和塑膠(jiao)。
