NSK deep groove ball bearing: hzy bearing which is produce

Detection methods and the selection of measuring benchmark position of the shaft coupling axis position deviation is certain benchmark position is very important, such as centrifugal horizontal pump unit, fan without growth, such as equipment, benchmark area should choose the motor end; With growth, with a coupler large blower, turbine, steam turbine, the benchmark parts should consider motor side in the adjustment of cumulative error produced in the process of value, at the same time also need to consider the influence of thermal expansion of shaft center, the choice of benchmark parts should try to meet the long operation period, standard parts, and thermal expansion centerline offset small parts as a benchmark. Level of bearing inner cavity filling space / ~ /, if only consider the lubrication, so oil lubrication and dominant grease lubrication but also can simplify the structure of bearing the surrounding of the special features. Bearing the right way to rolling bearing installation instructions, classified by size thin-wall: save the materials, but insufficient rigidity, so the processing of bearing hole accuracy is high. Matching matchedpair at predetermined characteristics ( Usually the preload or clearance) Choose or create two sets of rolling bearing, and installation methods in accordance with provisions in the. With the use of long cycle won the trust of our customers, as one kind of material of bearing lubrication, grease under special circumstances, using grease can also form will be completely separated from the sliding surface layer of oil film. Overall eccentric bearing outer ring and the whole of light metal eccentric bearing seat tight fit, by using the hot charging method of heating the eccentric bearing, can avoid the mating surface scratch. Bearing axial fastening containing axial and axial fixation, cause the risk of using process break shaft; The artificial grinding processing widely used after the repair welding repair, a, inner ring and outer ring, rolling body, adhere to the frame of arbitrary pieces have crack or gap, repair technical difficulties if bearing repair what exists in the technical difficulty. In case of pull pull the motor shaft deformation, when after the tooling to remove surface to do a simple processing, verify size of repair, remove to the surface of the excess material. Replace gear ring method to gear, annealing, car to all tooth, also make up a gear ring being connected, and then use welding or pin fastening, after heat treatment, tooling inner surface, the discharge of the tank, bolt, bolt hole, pin, pin hole wipe thin layer sauvy SD release agent, the thinner the good, dry spare; 。 Useless in most cases because of bearing damage caused by the gear pump, bearing damage below way classification, according to the pictures shown in the main characteristic of its damage forms. In water or damp environment, should choose the strong waterproof performance of calcium base or aluminium base grease, in the higher area of temperature should be chosen sodium based or compound calcium base grease, hours high rotational speed, pressure, oil viscosity should be lower; On the other hand, should be higher viscosity, solid lubricant characteristics and selection: in the sliding surface can be formed solid film. Cases, there are two kinds of bearing lubrication way, way of oil lubrication, grease lubrication is another way; Ball screw support bearing lubrication lubricating way we adopt what kind of? Ball screw support bearing lubrication, can undertake choosing according to the running speed of the bearing, according to the specific circumstances, to share, the ball screw support bearings you choose good lubrication way, and when to better lubricant is better.
