Description
Technical field
The present invention relates to a kind of measuring instrument, particularly disclose a kind of radius of curvature measurement instrument, the Contact stress for ball bearing channel is measured.
Background technology
Raceway groove and the steel ball of ball bearing are tangent, and the Contact stress size of its raceway groove and variable effect performance and the life-span of bearing.Usually measure Contact stress in bearing industry with scraping chromosphere to realize, but this method can only judge whether qualified, can not provide exact numerical, and will rely on the experience of reviewer, with very large subjectivity.In addition, have a kind of more accurate instrumentation to measure Contact stress at present, but it is expensive, complicated operation, is not suitable for in-site measurement.
Summary of the invention
The object of the invention is to address the deficiencies of the prior art, disclose a kind of ball bearing Contact stress surveying instrument, directly can measure the Contact stress numerical value of ball bearing and the variable quantity in channel profile easily.Structure of the present invention is simple, directly can use in production scene.
The present invention is achieved in that a kind of ball bearing Contact stress measuring 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, described slewing equipment is also provided with poroid mechanism, calibration chock is placed in described poroid mechanism, 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 aims 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 Contact stress measuring instrument are fixed respectively, first make a reservation for the Contact stress numerical value of the ball bearing on bearing ring to be measured with milscale and determine the zero-bit of 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 Contact stress numerical bias change of bearing ring to be measured.The Contact stress 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 dial gauge gauge head this time dial gauge circular dial scale line read.
The invention has the beneficial effects as follows: the absolute measurement of the present invention in conjunction with milscale and the relative measurement of dial gauge, and utilize pivotal principle, directly can measure the Contact stress numerical value of ball bearing and the variable quantity in channel profile.The present invention has simple to operate, the feature that data are straightforward, and avoid existing with scraping the qualitative reaction of chromosphere inspection without numerical value, the Special precision instrument again than complicated is easy to operate, can carry out conveniently execute-in-place use.
