Oil seal of the test bed of the operating mode requirement: test spindle speed which can achieve 200 ~ 6000 r/min and whose precision is ﹪ is adjustable steplessly. and 20 ~ 250℃ scope. Every cycle can be divided for the order of three stages and a test is divided for 800 cycles. The mechanical structure system is mainly posed by the motor, the growth structure, the oil seal ring installing frame, oil pump, the constant temperature oil tank and oil supply loop. The testing oil temperature whose precision is 2℃ is to be automatic adjustable in the In order to achieve the highest speed to experiment with, we design a growth device—pulley institutions between the spindle and the motor. The main shaft of the transmission device is drived by a motor through the flat belt. The flat pulley is installed in the left end of main shaft and the oil seal ring installation frame the right side. The transmission device uses a pair of oil seal to seal and the ventilation with cold oil can act on bearings of cooling and lubrication.In addition, we also design respectively the stepless speed regulation system and temperature controlling system based on PLC. Respectively expound the principle, hardware and software of the control system of the oil seal test. Hydraulic system is made up of the constant temperature oil tank, oil filter, oil pump, heater, cooler and various controlling valve etc. The oil pump motor drives the pump to work. The oil filter are divided into two kinds: one is that the cold oil transits through the cold transmission device back to the fuel tank。液壓系統(tǒng)由恒溫油箱、油濾、油泵、加熱器、冷卻器以及各種控制閥門等組成。另外，也利用PLC分別對無級調(diào)速系統(tǒng)和溫度控制系統(tǒng)進行了設(shè)計。在主軸的左端裝有平皮帶輪, 其右端裝有油封環(huán)安裝架。為了達到試驗用最高轉(zhuǎn)速,我們在主軸與電機間設(shè)計了一個增速裝置——皮帶輪機構(gòu)。一次試驗為800 個周期。試驗用油溫在20～250 ℃范圍內(nèi)自動可調(diào)，精度為2℃。 摘 要對新工況下的車用油封試驗臺，進行了機械系統(tǒng)、控制系統(tǒng)和液壓系統(tǒng)的全面設(shè)計。油封試驗臺的工況要求：試驗主軸轉(zhuǎn)速200～6 000 r/ min ,無級可調(diào), %。每周期的秩序為3 個階段。機械結(jié)構(gòu)系統(tǒng)主要由電機、增速結(jié)構(gòu)、油封環(huán)安裝架、油泵、恒溫油箱及供油回路組成。傳動裝置的主軸由交流電機通過平皮帶來帶動。傳動裝置由一對油封來密封, 運轉(zhuǎn)時通入冷油對軸承進行冷卻與潤滑。分別闡述了油封式試驗臺控制系統(tǒng)的原理，硬件和軟件。油泵電機驅(qū)動油泵工作,油液從油箱經(jīng)過濾分為兩路：一路冷油經(jīng)傳動裝置回油箱；一路經(jīng)加熱器加熱, 再輸入油封環(huán)安裝架, 其回油經(jīng)冷卻器冷卻后再回油箱。 Another is that the oil is heated by a heater, then enter oil seal ring installation frame and e back again to the oil tank with the cooler cooling.
