氣缸
下面是氣缸理論出力的計(jì)算公式:
F:氣缸理論輸出力(kgf)
F′:效率為85%時(shí)的輸出力(kgf)--(F′=F×85%)
D:氣缸缸徑(mm)
P:工作壓力(kgf/cm2)
例:直徑340mm的氣缸,工作壓力為3kgf/cm2時(shí),其理論輸出力為多少?芽輸出力是多少?
將P、D連接,找出F、F′上的點(diǎn),得:
F=2800kgf;F′=2300kgf

在工程設(shè)計(jì)時(shí)選擇氣缸缸徑,可根據(jù)其使用壓力和理論推力或拉力的大小,從經(jīng)驗(yàn)表1-1中查出。
例:有一氣缸其使用壓力為5kgf/cm2,在氣缸推出時(shí)其推力為132kgf,(氣缸效率為85%)問:該選擇多大的氣缸缸徑?
●由氣缸的推力132kgf和氣缸的效率85%,可計(jì)算出氣缸的理論推力為F=F′/85%=155(kgf)
●由使用壓力5kgf/cm2和氣缸的理論推力,查出選擇缸徑為?63的氣缸便可滿足使用要求。
