免鍵高(gao)扭矩同步帶輪(lun)P8M型由(you)(you)輪(lun)緣、輪(lun)輻(fu)和(he)輪(lun)轂(gu)三部分組成。設計帶輪(lun)時，應使(shi)其結(jie)構便于制(zhi)造，質量(liang)分布(bu)均勻，重(zhong)量(liang)輕，并避免由(you)(you)于鑄造產生過大的內應力。

當(dang)V>5m/s時進(jin)行靜(jing)平衡，當(dang)v > 25m/s時進(jin)行動平衡。同(tong)(tong)步(bu)帶輪(lun)材料中常(chang)用(yong)(yong)(yong)灰鑄鐵(tie)、45#鋼、鋁合金、銅或工(gong)程塑料。灰鑄鐵(tie)應用(yong)(yong)(yong)廣泛，當(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(tie)開鑄鋼件，也(ye)能(neng)用(yong)(yong)(yong)厚鋼板沖壓模具一電焊焊接(jie)同(tong)(tong)步(bu)帶輪(lun)。小輸出功率傳(chuan)動系(xi)統能(neng)夠(gou)用(yong)(yong)(yong)鋁鑄和塑膠。
