Abstract
The utility model provides a groove curvature radius measuring instrument for ball bearings, which comprises a micrometer and a dial gauge. The instrument is characterized in that the micrometer is additionally provided with a slewer. The revolution center of the slewer coincides with the zero position of the dial gauge. The slewer is provided with a hole-shaped mechanism internally provided with a calibration plug block. The working surface of the calibration plug block is exactly the revolution center of the slewer, namely the zero position of the dial gauge. When the calibration plug block is taken out of the hole-shaped mechanism, an indicating gauge is placed in the hole-shaped mechanism. The measuring probe of the indicating gauge is aligned with the measuring rod of the micrometer. The movement direction of the slewer and the movement direction of the measuring rod of the micrometer are mutually perpendicular. During the measurement of a ball bearing, the value of the groove curvature radius of a ball bearing is predetermined by the micrometer and the zero value of the indicating gauge is also determined. Then the measuring probe of the indicating gauge is in contact with the groove profile of the ball bearing. After that, the measuring probe of the indicating gauge is driven by the slewer to swing along the groove arc surface of the ball bearing. The change of the indicating gauge in value is just on behalf of the deviation change of the groove curvature radius of the ball bearing of a to-be-measured bearing ring in value. That means, the measurement on the groove curvature radius of the ball bearing is realized.
Description
Technical field
The utility model relates to a kind of measuring instrument, particularly discloses a kind of radius of curvature measurement instrument, for the ditch radius of curvature measurement of ball bearing channel.
Background technology
Raceway groove and the steel ball of ball bearing are tangent, performance and life-span that the ditch radius of curvature dimensions of its raceway groove and variable effect bearing.Conventionally measure ditch radius-of-curvature in bearing industry and realize with scraping chromosphere, but that this method can only judge whether is qualified, can not provide accurate numerical value, and will rely on reviewer's experience, with very large subjectivity.In addition, have at present a kind of more accurate instrumentation can measure ditch radius-of-curvature, but it is expensive, complicated operation, is not suitable for in-site measurement.
Summary of the invention
The purpose of this utility model is to address the deficiencies of the prior art, and discloses a kind of ball bearing ditch radius of curvature measurement instrument, can directly measure easily the ditch radius-of-curvature numerical value of ball bearing and the variable quantity in channel profile.The utility model ，Neng simple in structure is directly used production scene.
The utility model is achieved in that a kind of ball bearing ditch radius of curvature measurement instrument, comprise milscale and dial gauge, it is characterized in that: on described milscale, set up slewing equipment, the centre of gyration of described slewing equipment overlaps with the zero-bit of milscale, on described slewing equipment, be also provided with poroid mechanism, in described poroid mechanism, place calibration chock, the workplace of calibration chock is exactly the centre of gyration of slewing equipment, also be the zero-bit of milscale simultaneously, dial gauge is placed after removing calibration chock by described poroid mechanism, the gauge head of dial gauge is aimed at the measuring staff of milscale, the moving direction of slewing equipment is mutually vertical with the measuring staff moving direction of milscale, bearing ring to be measured and ball bearing ditch radius of curvature measurement instrument are fixed respectively, first by the ditch radius-of-curvature numerical value of ball bearing on the predetermined bearing ring to be measured of milscale the zero-bit of definite dial gauge, the gauge head of dial gauge is contacted with the channel profile of ball bearing ditch on bearing ring to be measured, recycling slewing equipment drives the gauge outfit of dial gauge to swing on the raceway groove circular arc of ball bearing ditch, numerical value change on dial gauge is the ball bearing ditch radius-of-curvature numerical value change of error of bearing ring to be measured.The ditch radius-of-curvature numerical value of ball bearing channel point comprises integral part and fraction part, and the numerical value of integral part is read by the scale label line on the measuring staff of milscale, fraction part by the gauge head of dial gauge this time dial gauge circular dial scale line read.
The beneficial effects of the utility model are: the utility model is in conjunction with the absolute measurement of milscale and the relative measurement of dial gauge, and utilize rotating principle, can directly measure the ditch radius-of-curvature numerical value of ball bearing and the variable quantity in channel profile.The utlity model has simple to operately, the feature that data are straightforward, has avoided existing use to scrape chromosphere check without the qualitative reaction of numerical value, more easy to operate than complicated Special precision instrument again, can carry out conveniently execute-in-place and use.
