Description
(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ МОМЕНТА СОПРОТИВЛЕНИЯ ВРАЩЕНИЮ ПОДШИПНИКА(54) DEVICE FOR MEASUREMENT OF THE MOMENT OF RESISTANCE TO BEHAVIOR ROTATION
Изобретение относитс к подшипниковой промышленности и может быть использовано дл измерени момента сопротивлени вращению подшипника.The invention relates to the bearing industry and can be used to measure the moment of resistance to rotation of a bearing.
Известно устройство дл измерени момента сопротивлени вращению подщипника, s содержащее смонтированные в корпусе приводной вал дл установки внутреннего кольца и испытуемого подшипника, цилиндрическую оправку дл фиксации наружного кольца и нагружени подшипника, охватываемую гибкой нитью, св занную с корпусом одним концом посредством упругого элемента , моментомер, подвижна часть которого соединена с оправкой 1.A device is known for measuring the moment of resistance to rotation of a support, s containing a drive shaft mounted in a housing for mounting an inner ring and a bearing under test, a cylindrical mandrel for fixing the outer ring and loading the bearing, covered by a flexible thread, connected to the body by one end by means of an elastic element, a torque meter, the movable part of which is connected to the mandrel 1.
Однако это устройство характеризуетс низкой точностью измерени .15However, this device is characterized by low measurement accuracy .15
Цель изобретени - повышение точности измерени момента сопротивлени вращению подшипника.The purpose of the invention is to improve the accuracy of measuring the moment of resistance to rotation of the bearing.
Поставленна цель достигаетс тем, что устройство содержит смонтированные в кор- д пусе приводной вал дл установки внутреннего кольца испытуемого подщипника, цилиндрическую оправку дл фиксации наружного кольца и нагружени подщипника.This goal is achieved in that the device contains a drive shaft mounted on the core for mounting the inner ring of the test liner, a cylindrical mandrel for fixing the outer ring and loading the liner.
