90R055DD液壓缸的計算(圖1)

?液壓缸的計算 液壓缸的主要尺寸包括:液壓缸內徑D、活塞桿直徑d、液壓缸缸體長度L 液壓缸內徑D 1根據最大總負載和選取的工作壓力來確定 2根據執(zhí)行機構速度要求和選定液壓泵流量來確定 根據最大總負載和選取的工作壓力來確定 以單桿缸為例:無桿腔進油時?D=√4F1/π(p1-p2)-dp2/p1-p2 有桿腔進油時D=√4F2/π(p1-p2)+dp1/p1-p2 如果初步選擇回油壓力p2=0,以上兩種簡化為:無桿腔進油時,D=√4F1/πp1 有桿腔進油時?D=√4F2/πp1+d 根據執(zhí)行機構速度要求和選定液壓泵流量來確定 無桿腔進油時:D=√4qv/πv1 有桿腔進油時:D=√4qv/πv1+d 計算得到的液壓缸內徑(即活塞直徑)應為標準值 (二)活塞桿直徑d 原理:活塞桿直徑可根據工作壓力或設備類型選擇液壓缸的往復速度比有一定要求的時候 d=D√λv-1/λv 計算所得活塞桿直徑d亦應圓整為標準系列值。

(三)液壓缸缸體長度L 原則:由液壓缸最大行程、活塞寬?度、活塞桿導向套長?度、活塞桿密封?長度和特殊要求的 確定其他長度為了降低加工難度,液壓缸體的長度一般不是?內徑應大于20-30倍 缸筒壁厚δ 確定原則:中低壓系統(tǒng),無需校核;高壓大直徑時,必須校核δ 缸筒壁厚δ校核方法 薄壁缸體(無縫鋼管): 當δ/D≤0.08時δ≥pmaxD/2[б] 厚壁缸體(鑄造缸體): 當δ/D=0.08——0.3時 δ≥pmaxD/2.3[б]-3pmax 當δ/D≥0.3時 δ≥D/2[√[б]+0.4?py/[б]-1.3py-1] 液壓缸其它部位尺寸的確定 導向長度H≥L/20+D/2(L為液壓缸最大行程) 活塞寬度B=(0、6——1、0)D; A=(0.6—10)D(D<80mm) 導向套滑動面長度A A=(0.6—1)d(D≥80mm) 如裝有隔套K時,C=H-(A+B)/2 液壓缸其它部位尺寸的確定 活塞桿長度由L確定,必要時需進行穩(wěn)定性驗算。

當液壓缸承受軸向壓縮載荷時: 若l/d≤15時,無須驗算 驗算l/d≥15時,可按材料力學有關公式進行 90-L-075-KN-5-NN-80-R-4-S1-D-03-GBA-38-38-24 90L075KN5NN80R4S1D03GBA383824 90L075-KN-5-NN-80-S-3-C7-D-03-GBA-42-42-24 90L075KN5NN80S3C7D03GBA424224
