Abstract
Изобретение относитс к машиностроению и может быть использовано дл определени износа поршневых колец двигателей внутреннего сгорани . Цель изобретени состоит в повышении достоверности измерений. Способ определени износа поршневых колец заключаетс в том, что на изнашиваю- ш.ейс повехности кбльца выполн ют лунки попарно одна против другой так, чтобы их образующие поверхности располагались под острым углом 6-12° к изнашивающейс поверхностней измер ют рассто ние между обращенными друг к другу вершинами парных лунок. Затем подвергают кольцо испытани м на износ, повтор ют измерени и определ ют величину h износа по формуле h The invention relates to mechanical engineering and can be used to determine the wear of the piston rings of internal combustion engines. The purpose of the invention is to increase the reliability of measurements. The method of determining the wear of piston rings is that on the wear surface of the cylinder, holes are made in pairs one against the other so that their forming surfaces are at an acute angle of 6-12 ° C. to the wearing surface, the distance between the vertices of the paired wells facing each other is measured. The ring is then subjected to wear tests, measurements are repeated and the wear value h is determined by the formula h
Description
Изобретение относитс к машиностроению и может быть использовано дл определени износа поршневых колец двигателей внутреннего сгорани .The invention relates to mechanical engineering and can be used to determine the wear of the piston rings of internal combustion engines.
Цель изобретени - новышение достоверности за счет оптимального выбора из- мерительных баз.The purpose of the invention is to increase reliability due to the optimal choice of measurement bases.
На фиг. 1 показана схема расположени лунок на изнашиваюш.ейс поверхности кольца; на фиг. 2 - схема дл вычислени радиального износа кольца.ЮFIG. Figure 1 shows the layout of the holes on the wearing out of the ring surface; in fig. 2 is a diagram for calculating the radial wear of a ring.
Схема содержит испытуемое кольцо 1 с лунками 2 и 3 на его изнашивающейс поверхности.The circuit contains test ring 1 with holes 2 and 3 on its wear surface.
Способ осуществл ют следующи.м образом .The method is carried out in the following manner.
На изнашивающейс поверхности кольца 5 1 выполн ют лунки 2 и 3, например, алмазным кругом толпдиной 2-3 мм с режущей кромкой полукруглой формы. Лунки 2 и 3 располагают попарно одна протин другой так, чтобы их образующие поверхности располагались под острым углом а 6-12° к изнашивающейс поверхности. Затем измер ют рассто ние 1н между обраш,енными одна к другой вершинами парных лунок 2 и 3, подвергают кольцо 1 испытани м и снова изh tga,On the wear surface of the ring 5 1, wells 2 and 3 are made, for example, with a diamond circle of 2-3 mm with a cutting edge of a semicircular shape. Wells 2 and 3 are positioned in pairs, one protin another so that their forming surfaces are located at an acute angle of 6-12 ° to the wearing surface. Then, a distance of 1N between the vertices of pairwise holes 2 and 3, one to another, is measured, ring 1 is subjected to tests and again from h tga,
где IK и 111 - рассто ни между обращенными одна к другой вершинами парных лунок соответственно до и после испытаний;where IK and 111 are the distances between the vertices of the paired holes facing one another and before and after the tests, respectively;
ос -угол наклона образующей поверхности лунки к изнащивающей- с поверхности кольца. Количество и ориентацию парных лунок 2 и 3 выбирают в зависимости от решаемых при исследовании задач.wasps - the angle of inclination of the forming surface of the hole to the wear - from the surface of the ring. The number and orientation of paired holes 2 and 3 are selected depending on the tasks to be solved in the study.
