Description
Technical field
The utility model belongs to measurement mechanism, particularly digital display type rotary support raceway diameter measurement mechanism.
Background technology
In general, radial load is less than the pivoting support of axial load 10%, can not consider the impact of radial load during design.And bear the pivoting support of larger radial load, then must consider the impact of radial load.This kind of pivoting support requires to have good lubricating condition, and after making it be heated, reason does not expand and stuck.For this reason for the pivoting support bearing larger radial load, certain end play and radial play must be ensured.The existence in gap, the change that radial load must be caused to distribute, causes the increase of maximum load of rolling body.Calculate according to the life-span, the cube of bearing life and load of rolling body is inversely proportional to.Therefore, radial clearance size is very large on bearing life impact, must think better of during design.
Because pivoting support raceway is generally arc, conventional measuring appliance such as Centigrade scale, milscale etc. cannot be located raceway to be measured thus cannot realize effective measurement.At present, the mensuration of rotary support raceway diameter adopts measuring stick, and measuring stick measurement mechanism limited precision, the error accumulation formed in measuring process affects measuring accuracy, especially inside and outside raceway measuring basis is inconsistent, on the impact of final assembly qualified rate greatly, the cost of manufacture of pivoting support is added.
Summary of the invention
Technical problem to be solved in the utility model is to provide digital display type rotary support raceway diameter measurement mechanism, structure is simple, easy to operate, can detect raceway central diameter inside and outside pivoting support lasso with same device, and can direct reading, unifying datum, accuracy rate is high, processing for pivoting support raceway offers precise data support, thus improve the crudy of pivoting support raceway, improve pivoting support radial load holding capacity, improve pivoting support serviceable life.
For achieving the above object, the digital display type rotary support raceway diameter measurement mechanism that the utility model proposes, it comprises spacing left measuring jaw, left amount ball, holding screw, measuring jaw fixed cover, the vernier caliper blade of band digital display panel, right amount ball and the right measuring jaw of vernier; Vernier caliper blade with digital display panel comprises chi bar, digital display panel and lock-screw, chi bar left part is fixedly installed downward left boss, digital display panel can be slided and be fixed by lock-screw in chi bar horizontal direction, and described digital display lower panels is fixedly installed right boss; Spacing left measuring jaw is connected with the left boss being arranged on chi bar left part with holding screw by measuring jaw fixed cover, the right measuring jaw of vernier is connected with the right boss being arranged on digital display lower panels with holding screw by measuring jaw fixed cover, is all connected with dovetail key by dovetail groove between described spacing left measuring jaw with left amount ball, between the right measuring jaw of vernier with right amount ball; The centre of sphere of described left amount ball is on left boss center line, and the centre of sphere of right amount ball is on right boss center line, and described left amount ball is identical with right amount gauge ball lattice, their radius all equals the radius of rolling body in pivoting support raceway to be measured.
During use, first digital display type rotary support raceway diameter measurement mechanism is directly measured raceway, and then adopt standard gauge block to demarcate testing result, to correct this measurement mechanism, can measure after correction, the reading on digital display panel is the diameter of pivoting support raceway to be measured.
The digital display type rotary support raceway diameter measurement mechanism that the utility model proposes, structure is simple, easy to operate, can detect raceway central diameter inside and outside pivoting support lasso with same device, and can direct reading, unifying datum, accuracy rate is high, processing for pivoting support raceway offers precise data support, thus improve the crudy of pivoting support raceway, improve pivoting support radial load holding capacity, improve pivoting support serviceable life.
