Miniature bearing measurement adjustment method

Hand press lever 1, remove the channel standard parts, with a little red on the channel, then set on the protection and measuring point, the point contact surface of the channel and the proper pressure, then rotate the ring the fulcrum and the site of the sphere contact with the channel, and by adjustment of the three pivot point of spherical biggest consistent contact with the channel trace, must make in same vertical plane (4) three pivot mount instrument 1, standard parts are on the table, and further fine tuning can be fine-tuning mechanism, when the table must be an standard datum toward the instrument, measurement, sensing channel diameter deviation from the table, groove diameter changes within a single radial plane. (5) mount instrument Ⅲ, standard parts on the groove position measuring areas symbol on the groove position measurement point, and then on to the table, make the probe contact ring reference face. Measurement, can be read from the table channel position deviation, the center of the channel for reference face flat on both ends of the line and symmetry in the face of the center of the channel. 6 in order to check the instrument adjusted stability, using standard parts installed, remove a few repetitions of operation, the instrument pointer refers to is still in the original position, if the same, namely the adjustment. 5. DO22 in gully inside the meter D022 measuring instrument is mainly used to check the bearing inner ring groove diameter, amount of groove diameter changes within a single radial plane, groove position and the channel for reference face parallelism and symmetry trench ( 1) The structure of the instrument is mainly composed of two parts base and trough plates, they together by bolts. Under the trough plate parts have two chute, ring channel spherical positioning protection is installed on the slider in the chute. Above the trough plate parts have leverage cylindrical shaped pressure protection 2, led ring close to the location below pivot, 1 and 4 in the pivot point 1 is equipped with the diameter of the corresponding direction finder table I, the diameter of the channel can be measured, as shown in figure 2. 18. Instrument Ⅱ symmetry gully location and measurement
