Jiaxing bearing | how to measure the bearing and the bearing hole size?

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. （ 1) Bearing hole of the bearing hole of the measurement can be used inside diameter scale after checking the basic dimension measurement on the outside micrometer, at the same time also need to bearing hole of the roundness and cylindricity measurement. Burn out bearing often makes the bearing hole in the narrow opening diameter and roundness error, the bearing to the detriment of the normal work of the. If on the surface of the connecting rod bolt positioning with kuang, connecting rod bearing cap will shift to make bearing hole of the roundness error. Bearing bearing hole of the roundness error should be controlled within the dimensional tolerance, and cylindricity should be strictly controlled. （ 2) Bearing the main size measurement (1) the thickness of the bearing: will change by the plane fixed outside micrometer probe into sphere, can be used to measure the thickness of the bearing. The thickness of the bearing generally should be controlled in 0. 005-0. 010 mm range, otherwise it will make the bearing inner diameter super bad. Bearing in recent if there are traces of thinning, should be careful when measuring. (2) with the bearing and the bearing hole tightness: cooperate with tightness is bearing more than the amount of free bounce off and surface height to ensure. Measurement under lap height: fit up bearing by the regulation, pay the bearing cap bolts to loosen one after the torque bolt, measured with a feeler clearance of the bearing cover outlet, its value should be zero. 05 ~ 0. 15 mm range. (3) bearing inside diameter: before measuring the bearing must be installed by the regulation combined torque tighten bearing cap bolts by the regulation, with inner scale, colonel in outside micrometer to measure after the benchmark size, measurement to avoid thinned area. Bearing inside diameter and the corresponding value is the difference between the axis neck diameter size fit clearance. (4) main bearing inner hole alignment: main bearing hole of the alignment error is mainly the bearing hole of the alignment error, and the causes of bearing hole alignment error is the deformation of the cylinder block. When the main journal radial circular runout tolerance, check the main journal and bearing the mark, if eat each main bearing the mark position is obviously not consistent, that alignment error is big, can be used for skiving, boring bearing or changing the solution to such as cylinder block, otherwise difficult to guarantee the normal work of the engine.
