Problems solved by technology

However, such a structure is only suitable for measuring the perpendicularity of the cage beam to the bottom surface, that is, the inclination of the cage pocket in the circumferential direction, but cannot measure the inclination of the cage pocket in the radial direction, which does not meet the measurement requirements

Abstract

The invention discloses a needle bearing retainer aperture indirectly measuring device which comprises a measuring platform base, a first measuring assembly, a second measuring assembly, a measuring block and an elastic deforming body, wherein the measuring platform base is used for placing a retainer, the measuring block is fixed in an aperture of the retainer through the elastic deforming body, the first measuring assembly is arranged on the outer end face of the measuring block and used for measuring gradient of the aperture of the retainer in the diameter direction, and the second measuring assembly is arranged on the side face of the measuring block and used for measuring gradient of the aperture of the retainer in the circumferential direction. Through the method, the needle bearing retainer aperture indirectly measuring device is simple in structure, convenient to operate, capable of measuring the gradient of the aperture of the retainer in the diameter direction and the gradient of aperture of the retainer in the circumferential direction at the same time, and clear at a glance in numerical value.

Description

technical field [0001] The invention relates to the technical field of bearing measurement, in particular to an indirect measuring device for the inclination of a window hole of a cage of a needle bearing. Background technique [0002] When the needle roller bearing is working, the cage needs to guide the needle roller to roll on the correct track. Otherwise, the needle will be stuck, which will affect the pass rate of the needle roller bearing. The inclination of the window hole is the main parameter to judge whether the cage can guide the needle roller correctly. [0003] For the inclination of the window hole, the industry standard JB / T 10337-2002 provides a schematic diagram, and the measured value is a comprehensive value. In general, what we mainly control is the inclination in the diameter direction of the cage, and the inclination in the circumferential direction is generally not required. Furthermore, the aperture inclination cannot be measured with other measurin...
