Test device for life span of materials roller bearings

摘要

Test device for life span of materials roller bearings consists of a frame (11), on which a upper plate (3) and the lower plate (4), which are linked together by a spacers (7). The upper plate (3) and the lower plate (4) are displaceably arranged two fixed supports (6) vertically-mounted pressure roller (10). The upper plate (3) and the lower plate (4) it is positioned and frictionally slide the loading lift (5) vertically-mounted pressure roller (10). The intersection line feeds two solid supports (6) of the pressure cylinder (10) with the intersection line feed load carrier (5) of the pressure roller (10) in the chuck (1) of the rotary actuator vertically clamped test rod (2). In the intersection line feeds two solid supports (6) of the pressure cylinder (10) with the intersection line feed force-load carrier (5) of the pressure roller (10) is between the upper plate (3) and the bottom plate (4) arranged in a fixed cage (8) and there are vertically disposed three distance rollers(9). Distance rollers (9) are in the line relations cylindrical surfaces in contact on one side with a pressure roller (10), and at the second side with the test rod(2).
