Abstract
Изобретение относитс к области испытани материалов на трение и износ. Целью изобретени вл етс повышение точности за счет того, что на валу 10 установлена оправка 9, котора выполнена в виде полой втулки с выступом 1 1 на торце. Дп исключени опрокидывающего момента рассто ние между осью 12 держател 2 и осью 13 вала 10 выбирают не превышающим радиус образца 3. Выступы 11 используют дл базировани и креплени контртела. 2 ил. kfl V « фи. 2This invention relates to the field of materials friction and wear testing. The aim of the invention is to improve the accuracy due to the fact that on the shaft 10 is mounted a mandrel 9, which is made in the form of a hollow sleeve with a protrusion 1 1 on the end. Dip the exclusion of the tilting moment, the distance between the axis 12 of the holder 2 and the axis 13 of the shaft 10 is chosen not to exceed the radius of the sample 3. The protrusions 11 are used to base and fasten the counterbody. 2 Il. kfl v «fi. 2

Изобретение относитс к технике испытани материалов на трение и износ.This invention relates to a technique for testing materials for friction and wear.
Целью изобретени вл етс повышение точности.The aim of the invention is to improve the accuracy.
На фиг,1 представлена машина дл испытани на трение и износ; на . фиг,2 - узел трени .Fig. 1 shows a machine for friction and wear testing; on . Fig, 2 - friction knot.
Машина содержит станину 1, держатель 2 образца 3, узел А дл креплени держател 5 (фиг,2), контртела 6, узел 7 нагружени образца 3 и контртела 6, привод 8 вращени держ тел 2, Машина (фиг.2) снабжена оправкой 9, установленной на валу 10 узла 4 выполненной в виде полой втулки с выступом 11 на торце дл базировани и креплени контртела б а рассто ние между осью 12 держател 2 образца 3 и осью 13 вала 10 узла 4 выбрано не превышающим радиу образца 3,The machine contains a frame 1, a holder 2 of sample 3, a node A for fastening the holder 5 (FIG. 2), a counterbody 6, a node 7 loading the sample 3 and a counter body 6, the rotational drive 8 holding the bodies 2, the Machine (figure 2) is provided with a mandrel 9 mounted on the shaft 10 of the assembly 4 made in the form of a hollow sleeve with a protrusion 11 at the end for locating and fixing the counterbody, and the distance between the axis 12 of the holder 2 of sample 3 and the axis 13 of the shaft 10 of the node 4 is selected not exceeding the radius of sample 3,
Машина содержит узел 14 дп измерени силы трени в зоне контакта образца 3 и контртела 6,The machine contains a node 14 DP measuring friction force in the zone of contact of sample 3 and the counterbody 6,
Машина работает следующим образом .The machine works as follows.
После установки образца 3 в держателе 2 и контртела 6 в узле 4 с поЖAfter installing the sample 3 in the holder 2 and the counterbody 6 in the node 4 with PU

мощью привода 8 вращают держатель 2, Узлом 7 нагружают образец 3 и контртело 6. Силу трени регистрируют с помощью узла 14 дп измерени указан- 5 ной силы трени . Износ оценивают весовым методом. Благодар выбору рассто ни между ос ми 12 и П. не пое- вышаюш.его радиус образца 3, опро- ки дываюш;ий момент, действующий на узел 4, сведен к минимуму, а контртело 6 в зоне контакта изнашиваетс равномерно.drive 8 rotates the holder 2, the node 7 load the sample 3 and the counterbody 6. The friction force is recorded using the node 14 dp measuring the specified 5 friction force. Wear is assessed by the gravimetric method. Due to the choice of the distance between axis 12 and P., its sample 3 radius, when tested on the test, the moment acting on node 4 is minimized, and the counterbody 6 in the contact zone wears evenly.
