Description

Изоб зетение относитс к области триболопга и может быть использевано дл определени износа узлов трени .The image is in the tribolop area and can be used to determine wear of the friction units.
Целью изобретени вл етс повы- шение технологичности за счет устранени необходимости взаимного ориент ровагш оси цилиндра и осей симметрии базы.The aim of the invention is to improve the manufacturability by eliminating the need for the mutual orientation of the cylinder axis and the axes of symmetry of the base.
На фиг. 1 изображена кольцева измерительна база по способу.,соответственно вид сбоку и вид в направлении оси канавки; на фиг. 2 - изменение формы базы при износе поверх ности на U .FIG. 1 shows an annular measuring base according to the method., Respectively, a side view and a view in the direction of the axis of the groove; in fig. 2 — change of the base shape when the surface is worn by U.
На исследуемой поверхности выполн етс база в форме кольцевой канавки с осью, перпевдикул рной образующей циливдрической поверхности и лелшщей в плоскости ее оси. The base of the test surface is formed in the form of an annular groove with an axis perpendicular to the generatrix of the cylindrical surface and located in the plane of its axis.
Из-за . искривленности цилиндрической поверхности глубина канавки плавно мен етс по ее длине, достига максимума в плоскости осей канавки и цилиндрической поверхности. Because of . the curvature of the cylindrical surface the depth of the groove smoothly varies along its length, reaching a maximum in the plane of the axes of the groove and the cylindrical surface.
Максимальную глубину канавки берут равной величине & предельно допустимого износа. При этом радиус г кольца канав1ш при Си «-К, где R - радиус цилиндрической поверхности, выбирают из услови The maximum depth of the groove is taken equal to the value of & maximum allowable wear. At the same time, the radius r of the ditch ring when C «-

Измерение износа согласно способу осуществл етс следующим образом.The wear measurement according to the method is carried out as follows.
аbut
R качестве геометрического параметра базы берут угловую координату крайних точек наружной кромки дна канавки (фиг. 1 и 2).R as the geometric parameter of the base take the angular coordinate of the extreme points of the outer edge of the bottom of the groove (Fig. 1 and 2).
Если дл неизношенной детали координата oi. есть i)i, (на фиг. 1 eto 180°), а после износа - , то износ & определ егс по формулеIf for unworn parts coordinate oi. there is i) i, (in Fig. 1 eto 180 °), and after wear, then wear & determined by formula
