force control測(cè)功機(jī)

force control測(cè)功機(jī)Positorq®剎車使用多盤油剪切技術(shù)，像其他部隊(duì)控制單元的冷卻和潤(rùn)滑液的持續(xù)供應(yīng)。 主要的區(qū)別是，force control測(cè)功機(jī)Positorq®剎車是一個(gè)常數(shù)的滑裝置。 它通常是強(qiáng)制潤(rùn)滑平滑的轉(zhuǎn)矩控制在整個(gè)速度范圍內(nèi)，甚至到0 RPM。 張力扭矩被傳遞通過(guò)的摩擦表面之間的流體的粘性剪切。

扭矩成正比的空氣或液壓壓力供給到活塞。 特氟隆活塞襯墊生產(chǎn)平穩(wěn)可控活塞運(yùn)動(dòng)的控制和制動(dòng)響應(yīng)快。

force control測(cè)功機(jī)張力控制和剎車測(cè)力計(jì)（測(cè)功機(jī)）本質(zhì)上是能量吸收。 旋動(dòng)通過(guò)制動(dòng)熱轉(zhuǎn)化，所以在制動(dòng)的一個(gè)關(guān)鍵功能是其散熱能力。 在Positorq®制動(dòng)，流體被泵送通過(guò)制動(dòng)軸的摩擦表面之間提供一個(gè)連續(xù)的流體供應(yīng)。 流體潤(rùn)滑表面的接合點(diǎn)，并刪除參與熱。 然后，該流體循環(huán)通過(guò)冷卻單元，冷卻的流體返回到的Positorq®制動(dòng)。

force control測(cè)功機(jī)Dynamometer (Dyno) Absorber Brakes

force control測(cè)功機(jī)The Positorq® Brakes use multiple disc oil shear technology with a continual supply of cooling and lubricating fluid like all other Force Control units. The main difference is that the Positorq® Brake is a constant slip device. It is normally force lubricated for ooth accurate torque control over the entire speed range, even to 0 RPM. Tension torque is tranitted through the viscous shear of the fluid between the friction surfaces.

Torque is proportional to air or hydraulic pressure supplied to the piston. Teflon piston liners produce ooth controllable piston movement for precise control and quick brake response.

Web tension control and dynamometer (dyno) brakes are essentially energy absorbers. Rotary motion is transformed through the brake to heat, so a critical function of the brake is its ability to dissipate heat. In the Positorq® brake, fluid is pumped through the brake shaft to furnish a continuous supply of fluid between the friction surfaces. The fluid lubricates the surfaces at the point of engagement, and removes engagement heat. The fluid is then circulated through a cooling unit and cooled fluid is returned to the Positorq® brake.
