免鍵高扭矩同(tong)步帶輪(lun)P5M型由輪(lun)緣、輪(lun)輻(fu)和輪(lun)轂三部分(fen)組成。設計(ji)帶輪(lun)時，應使其結構便于制造，質量分(fen)布均(jun)勻，重量輕，并避免由于鑄造產生過大(da)的內應力。

當V>5m/s時(shi)進(jin)行靜平衡(heng)，當v > 25m/s時(shi)進(jin)行動(dong)(dong)平衡(heng)。同(tong)步(bu)(bu)帶輪材料(liao)中(zhong)常用(yong)(yong)灰(hui)鑄(zhu)鐵、45#鋼、鋁(lv)合金、銅或(huo)工程(cheng)塑料(liao)。灰(hui)鑄(zhu)鐵應用(yong)(yong)廣泛，當V≤30m/s，V ≥ 25 ~ 45m/s時(shi)使用(yong)(yong)HT200。則宜(yi)選用(yong)(yong)創造生鐵開鑄(zhu)鋼件，也能(neng)用(yong)(yong)厚鋼板(ban)沖壓模(mo)具(ju)一電(dian)焊焊接同(tong)步(bu)(bu)帶輪。小輸出(chu)功率傳動(dong)(dong)系統能(neng)夠用(yong)(yong)鋁(lv)鑄(zhu)和塑膠。
