供應(yīng)鏈條與鏈輪的嚙合沖擊力
同時(shí)以降低高速傳動(dòng)過程中鏈條的波動(dòng)量和鏈條與鏈輪的嚙合沖擊力及提高從動(dòng)輪運(yùn)轉(zhuǎn)的平穩(wěn)性為基本原則,進(jìn)行了新型滾子鏈鏈輪齒形的研究。以滾子在齒根圓上作純滾動(dòng)為前提,得出了新型鏈輪的外擺線方程；利用包絡(luò)線求等距線的方法,推導(dǎo)出了新型鏈輪的齒廓方程；參照國標(biāo)鏈輪的設(shè)計(jì),得到了外擺等距線鏈輪的設(shè)計(jì)方法。
其次,基于三維建模技術(shù)建立了GB1244-85標(biāo)準(zhǔn)鏈輪、日本JIS B 1801-90標(biāo)準(zhǔn)鏈輪、外擺等距線鏈輪及與它們相配套的傳統(tǒng)滾子鏈傳動(dòng)模型。通過在ADAMS中添加旋轉(zhuǎn)副、驅(qū)動(dòng)力等約束,建立了以上三種滾子傳動(dòng)系統(tǒng)的多剛體系統(tǒng)動(dòng)力學(xué)模型。完成了主動(dòng)鏈輪轉(zhuǎn)速為1000-8000r／min時(shí)的仿真實(shí)驗(yàn),并從理論上提出了修正新型鏈輪齒形的方法。
Fluctuations in the amount of chain in the process of reducing high-speed transmissionchainsprocket meshing impactimprove the smoothness of the driven wheel operation as the basic principle of a new roller chain sprocket tooth. Pure rolling of the roller on the root circle as the premise, reached a new sprocket epicycloid equation; envelope seek equidistance line method to deduce the new sprocket tooth profile equation; reference to the GB the design of the sprocket outside placed equidistance line sprocket.
Secondly, based on three-dimensional modeling techniques GB1244-85 standard sprocket, Japan JIS B 1801-90 standard sprocket, placed outside the equidistance line sprocketmatching with their traditional roller chain drive models. ADAMS rotary vice, the driving force constraints, more than three roller transmission of multibody dynamics model. Completed a the active sprocket speed for 1000-8000r/min simulation experimenttheory proposed amendments to the new sprocket tooth.
