Rolling bearing clearance measurement

Measurement of rolling bearing clearance - 2021 01 - 21 graphic/PangQingMei 1 a, ready to work. Wear 2 labor protection. Select equipment and material 2, operation step 1. Wipe bearing rolling decent and cage 2. Check the bearing flexibility 3 rotation. According to the bearing size to choose the thickness of lead wire. Insert the lead wire rolling shaft body outer rail inside 5. Roller rotation rail within or outside the rail in lead filar silk scroll crushed lead wire of up to six. Take out get squashed the lead wire of stroke with the hand flat 7. Wipe the outside micrometer surface and face eight junior high. Measured with outside micrometer squished and le flat wire 9. Reading (1) fixed tube reading: read first fixed tube center line to show the dial on the number of the mm, upper the whole mm outside diameter micrometer to measure the number of 0 mm. To read several fixed tube in the offline side half a millimeter. If the rotation of the differential sleeve position more than half ( Fixed casing in the offline side showed a scale line) When should add 0 mm number behind. 50mm； If the rotation of the differential sleeve position is not more than half ( Fixed casing in the offline side without revealing half scale line) , do not add 0 mm number behind. 50 mm, the diagram should add 0 mm number behind. 50mm。 (2) the differential cylinder reading: look where a differential cylinder with fixed tube line alignment, read out the decimal part on differential cylinder ( A few percent mm) 。 Read differential cylinder number, read differential cylinder should be estimated one over ten of the scale, namely zero. 001mm。 Figure of differential cylinder outside micrometer reading to zero. 309mm。 (3) measured workpiece measurement value: + differential cylinder reading fixed tube. In the figure measured workpiece measurement value of 0. 5毫米+ 0。 309mm=0. 809mm。 10. With the method of retest 11 at a time. Record data ( Two measuring maximum number shall prevail) 12.
