塑料滑動(dòng)摩擦磨損試驗(yàn)機(jī)工作原理結(jié)構(gòu)特征
該機(jī)由主機(jī)、電控箱、計(jì)算機(jī)測(cè)控系統(tǒng)組成。主機(jī)（附圖a1）主要由鑄造機(jī)座及位于機(jī)座左部的力矩測(cè)量部分，中部的下試樣軸部分，右部的上試樣軸部分、偏心輪軸部分和試驗(yàn)力施加與測(cè)量部分組成。

塑料滑動(dòng)摩擦磨損試驗(yàn)機(jī)工作原理
上下試樣軸的運(yùn)轉(zhuǎn)
雙速電動(dòng)機(jī)（1）通過(guò)三角皮帶（2）齒輪（6）齒輪（7）齒輪（8）內(nèi)齒輪（9）帶動(dòng)下試樣軸（12），使其以200r/min（或400r/min）的轉(zhuǎn)速轉(zhuǎn)動(dòng)；通過(guò)三角皮帶（2）齒輪（6）齒輪（5）蝸桿軸（36）、滑動(dòng)齒輪（39）和齒輪（40）的傳遞，使上試樣軸（13）以180r/min（或360r/min）的轉(zhuǎn)速轉(zhuǎn)動(dòng)。當(dāng)上下試樣軸都轉(zhuǎn)動(dòng)且兩試樣直徑相等時(shí)，由于上下試樣軸轉(zhuǎn)速不等，（除滾動(dòng)摩擦外），則在試樣間帶有10%的滑差率，使試樣間具有滑動(dòng)摩擦；改變?cè)嚇又睆?，即可或減小滑差率，如要滑動(dòng)速度，將滑動(dòng)齒輪（39）移至右端與反向齒輪（17）嚙合，使上試樣軸（13）反向旋轉(zhuǎn)即可。為了試驗(yàn)時(shí)固定螺母松動(dòng)，下試樣軸（12）上的螺紋是左旋的，而上試樣軸（13）上的螺紋是右旋的。
上試樣軸的固定
當(dāng)做滑動(dòng)摩擦試驗(yàn)時(shí)，為使上試樣軸固定不動(dòng)，應(yīng)將滑動(dòng)齒輪（39）移至中間位置，并用螺釘（38）固牢，齒輪（40）須用銷(xiāo)子（41）固定在搖擺頭（37）上。
兩試樣間壓力（試驗(yàn)力）的調(diào)整
試驗(yàn)力是通過(guò)彈簧（15）的壓縮獲得的，其或減小，可用螺母（19）進(jìn)行調(diào)整，力值信號(hào)由傳感器（18）送入電控箱并在計(jì)算機(jī)顯示器上顯示。
摩擦力矩的測(cè)量
摩擦力矩等于下試樣半徑與摩擦力的乘積，此力矩通過(guò)內(nèi)齒輪（9）作用于齒輪（8）上，使擺架（4）及擺砣（3）產(chǎn)生偏轉(zhuǎn)，由位移傳感器（44）送入電控箱并在計(jì)算機(jī)顯示器上顯示。
下試樣軸轉(zhuǎn)數(shù)的測(cè)量
下試樣軸轉(zhuǎn)數(shù)通過(guò)轉(zhuǎn)數(shù)傳感器（11）測(cè)量并在計(jì)算機(jī)顯示器上顯示

Plastic sliding friction and wear testing machine work principle, structure characteristics
This machine is composed of host, electric cabinet, computer measurement and control system.Host (chart a1) is mainly composed of casting base and is in the left of torque measurement part of the frame, in the middle of specimen under shaft parts, on the right of the department of shaft and eccentric shaft part sample and test and measurement of parts.
This machine adopts double speed motor (kW) 2880/1440 RPM, 1/0.75 drive, power supply of 220 v / 50 hz, the wiring and electrical principle figure c for reference.
Plastic working principle of the sliding friction and wear tester
Sample axis running up and down
Two-speed motor (1) through the v belt (2) the pinion gear (6) (7) gear (8) (9) driven gear shaft (12) samples, to make it to 200 r/min (400 r/min) or the speed of rotation.Through the v belt (2) the gear (6) (5) the worm shaft gear (36), sliding gear (39) and gear (40), make sample shaft (13) to 180 r/min (360 r/min) or the speed of rotation.When the upper and lower shaft sample rotation and two equals the sample diameter, due to the fluctuation range sample shaft speed, except for the rolling friction, slip rate between the sample with 10%, is a sliding friction between sample;Change the sample diameter, can increase/decrease slip rate, to improve the sliding speed, the sliding gear (39) moved to the right side and the reverse gear mesh (17), make sample shaft (13) reverse rotation.In order to prevent the fixed nut loose, when testing the sample thread on the shaft (12) is left-handed, and sample shaft (13) on the thread is right.
Sample shaft fixed
As sliding friction test, for fixed sample on axis, sliding gear (39) should be moved to the middle position, and the screw (38) is fast, gear (40) must (41) with peg fixed on the swinging head (37).
The adjustment of the pressure between the two samples (test)
Test force is achieved through compression spring (15), the increase/decrease, nut adjustments (19) are available, and a strength signal from the sensor (18) into electric cabinet and displayed on the computer display.
Friction torque measurement
Friction torque is equal to the radius of the sample and the product of the friction, the torque through the internal gear (9), acting on the gear (8) the swing frame (4) and (3) the pendulum mound deflection, the displacement sensor (44) into electric cabinet and displayed on the computer display.
The sample the measurement of shaft revolution
Sample under shaft revolution by revolution sensor (11), measure and displayed on the computer display
