On the basis of the engage efficiency and lubricious conditions, theoretical transmission efficiency with the different drive ratios ( 1 / 50 and 6 / 31 ) of involute cylinder worm gears is analyzed. at the same time, the change trend of engage efficiency and transmission efficiency with different design parameters is discussed. the experimental investigation on transmission efficiency
從漸開線蝸輪蝸桿傳動的嚙合效率和潤滑條件兩個方面對不同傳動比的漸開線圓柱蝸桿的傳動效率進行理論分析,並通過傳動比分別為1 / 50和6 / 31的漸開線圓柱蝸桿設計參數得到蝸桿潤滑條件的理論分析結果和蝸桿嚙合效率、傳動效率的變化趨勢,同時利用電測法對蝸桿傳動的傳動效率、潤滑油平衡溫度進行測試,將測試數據與理論計算結果進行對比分析,得出理論分析結果的正確性。According to the characteristics of the overhead camshaft valve train, the author thoroughly analyzed the kinematics and dynamics concerned in the design of valve train cam profile. the results illuminate the influence of valve timing, ample factor as well as the contact stress between cam and tappet on the design of cam profile
根據頂置凸輪軸式配氣機構的特點,文章深入分析了在配氣凸輪型線設計中必須涉及的運動學及動力學問題,說明了配氣定時、豐滿系數及凸輪與挺柱間接觸應力對凸輪型線設計的影響。( 3 ) based on the experiments data, it has been found that if the emitter discharge of sdi was little, the depth of pipe buried should be shallow, and the distance between two micro holes should be chosen to equal or close the distance between two lateral pipes, if the emitter discharge of sdi was great, the pipe may be buried deeper, and the distance between two micro holes could be greater than the distance between two lateral pipes
根據一維土柱近似的濕潤輪廓線初步選定了工程設計參數。在地下滴灌灌水器出流量較小情況下,埋深應淺,孔距應選擇和毛管間距相等或接近;出流量大時,埋深可深,孔距大於毛管間距仍可獲得較均勻的土壤水分分佈。Abstract : in this paper, a kind of technological scheme for one - step precision forging spur gear with large module is put forward by using positive friction role. experiment, in which commercial pure lead is taken as test material, is done in the special die designed, and force vs. stroke curve is recorded. it is shown that positive friction role can efficiently make a contribution to the filling of the tooth cavity, but increase forming force
文摘:針對大模數直齒圓柱齒輪,提出了利用積極摩擦一步成形的工藝方案,並用工業純鉛作為試驗材料,在設計的專用模具上進行試驗,記錄了力? ?行程曲線,結果表明:利用積極摩擦作用能夠有效地保證直齒圓柱齒輪精鍛時齒腔充滿,但同時增加了變形力。The cutter location in nc generative ultrasonic grinding process for parallel ruled surface with cylindrical grinding wheel was analyzed, the structure of nc generative ultrasonic grinding device was introduced, the design of grinding spindle assembly and the spindle ' s driving scheme was also introduced, system hardware and software design had been finished
摘要分析了圓柱磨輪數控展成超聲磨削平行直紋面時的刀具空間位置,介紹了數控展成超聲磨削成形加工機床的總體結構,論述了磨輪主軸部件設計及主軸驅動方案,實現了主軸變頻調速控制系統軟硬體設計。The software can design many conventional type of cam, concluding cam - plate with middle follower, cam - plate with offset follower, cylindrical cam, dividing cylindrical cam, and cylindrical cam with space curve, etc. in forming working curves of cam - plate, used the approximation by arcs which can lessen the nodal points on curves of cam uttermostly in same error, so it reduce the computation time and relieve the chattering of principal axis. in former times, to cam mechanism, the follower only has one direction motion
本軟體可以設計的凸輪類型較多,包括了對心移動從動件盤形凸輪、偏置移動從動件盤形凸輪、圓柱凸輪、圓柱分度凸輪和空間曲線柱形凸輪等,其中對盤形凸輪的工作曲線採用了難度較大的圓弧逼近演算法和等誤差演算法,這樣就可以在相同的允許誤差內最大限度的減少生成曲線的節點數,減少計算時間,同時可以大大減輕加工中的振動現象。分享友人
