Description

This invention relates to a measurement technique and can be used in bearing manufacturing.

The purpose of the invention is to improve the accuracy of control and the expansion of the range of controlled bearing rings by controlling the taper of both the inner and outer ring of the taper bearing.

Figure 1 shows a diagram of an instrument for controlling the taper of the raceway of a ring of a tapered bearing during the control of the inner ring; figure 2 - the same, in the process of control of the outer ring: in fig.Z - location of the probes in height when checking the inner ring; figure 4 is the same, when controlling the outer ring.

The device includes a housing 1 with a base plane 2, on which is placed a clamping stop 3, made in the form of a prism. In the housing 1, the carriages 4 and 5 are mounted symmetrically to the anvil 3, which can move relative to each other along the guides 6 and are spring-loaded springs 7 to the separating cam 8 mounted on the roller 9. To the anvil 10 mounted on the carriage 4, by the springs 11, the bracket 12, which is able to move along the guides 13 mounted on the carriage 4; parallel to the carriage 4, a stop 14 is mounted on the carriage 5, to which a bracket 16 is pressed by springs 15, mounted for movement along the guides 17 of the carriage 5 parallel to the movement of this carriage. The brackets 12 and 16 are spring-loaded to the stops 10 and 14 in directions opposite to the directions of the spring-loaded carriages. On the brackets 12 and 16 on the flat parallel springs 18 in pairs are fixed holders 19-22 of the corresponding probes 23-26. The holders 19-22 are spring-loaded with springs 27 to the base plane 2. The measuring probes 23 and 25 of the holders 19 and 21 interact with the controlled surface of the ring 28 in the diametrically opposite direction and are displaced along

the height of the raceway relative to the probes 24 and 26 of the holders 20 and 22. The holder 19 is connected to the holder 21 by the gauge 29, and the holder 20 with the holder 22 by the gauge 30. On the case 1, the gauges 31 and 32 are mounted, respectively, of the brackets 12 and 16 relative to the case

The device works as follows.

First set up the device. To do this, moving the cam 8 apart by turning the roller 9 of the carriage 4 and 5, set the reference gauge (rings 28) on the reference plane 2, pressing it against the clamping stop 3. After this, the roller is turned

9 with the cam 8 at 90 °. At the same time, the carriages 4 and 5 approach, and together with them the brackets 12 and 16 mounted on them with the holders 19-22 of the probes 23-26, respectively, which begin to contact with the reference gauge. At the same time, the cam 8 leaves the interaction with the carriages 4 and 5. By adjusting the position of the stops 10 and 14. the brackets 12 and 16 pressed against them are set to a predetermined position - conditional zero, adjusting it according to the gauges 31 and 32 of the brackets. The indications of gauges 30 and 29 are taken as conditional.

zeros.

Then proceed to the measurement. For this, the roller 9 with the cam 8 is rotated by 90 °. the carriages 4 and 5 are separated, the model measure is removed, and instead the control ring 28 is placed on the measurement position. After that, the roller 9 is rotated 90 ° again, the cam 8 leaves the interaction with the carriages 4 and 5. That leads to the pressing of the probes 23 by the springs 7 -26

to the conical surface of the ring to be measured. Adjusting the positions of the stops

10 and 14, according to the indications of the meters 31 and 32, achieve the specified zero positions of the brackets 12 and 16, i.e. the same as

when tuned to an exemplary measure, which achieves compensation for the influence on the measuring forces of different degrees of deformation of the springs 7, thereby achieving a high measurement accuracy. According to the difference in readings of gauges 30 and 29, in rchzalny personal cross-sections of the measured ring 28 judging the taper of its raceway.
