Roller bearings, bearing two bearing in a side how to design

Sealing ring TT: retaining ring type teflon bearing seals, mainly for the miniature bearing, the join of glass fiber teflon sealing ring with a spring ring is fixed on the outer ring structure. According to the different material model of axial fan operating temperature is chosen, sauvy SDH, the material is widely used in degrees Celsius in the environment of equipment wear and tear of various axial fan bearing such as bit wear, bearing chamber wear, etc. ; 。 The installation of the bearing ( Including the reinspection situation before installation bearing size tolerance) , bearing the original clearance, assembly and in the case, the bearing seat and rigid frame, installation whether there are abnormal. Roller end surface scratch, usually bearing steel surface hardness value of raw materials ( HRC） For ~ by after heat treatment process of bearing steel ball surface hardness value can achieve ~. Solutions: to improve the lubrication method, began in fatigue, the number of the wafer will increase obviously, this can be as a sign of fatigue appeared together with the spherical particles. Bearing WeChat professional! In addition, low friction torque bearings should avoid using contact seal, at the same time, the recommended oil drip lubrication, lubrication oil and gas or other beneficial to reduce friction lubrication method. Bearing failure, if there are no immediate solutions for problems, hastened the motor fault, according to the fluke, % of motor fault directly attributed to bearing damage. Hot charging bearing according to the requirement, and vertical pump, pump shaft in the vertical position according to the volute pump impeller out of the way classification: after water out of the impeller, directly into the pump shell have a shape of a helix. Separation of internal bearing grease quantity too little, and ball bearing channel is insufficient lubrication, turn the sound; , release bearing internal cleanliness is poor, which leads to the rotating binding; 。 Good use can read the number of filling greasing, so hope for the installation of the bearing design and installation department should fully explore, and installed in accordance with the operating standards. Ceramic coating can prevent current through, with insulating ability, bearing insulation selection of the general, completely off the inside of the bearing potential difference is very difficult. Cage cage processing process, in accordance with the design of the structure and the different raw materials, and can be divided into the following two categories: sheet metal shear [ ] To blanking, stamping, and finishing to pickling or shot peening or string light, final inspection to rust, packaging, warehousing, For sets of assembly) Entities cage: processing entity cage processing, according to the difference of the raw materials or bad MAO and differ somewhat, including car before the processing can be divided into the following types of blank type, the whole process is: bar, pipe material, forging, casting - - - - Car inside diameter, outside diameter, end face, chamfering. . . - - - Drilling ( Or pull holes, boring) - - - - Pickling - - - - Final inspection - - - - - - - - - - - - - - - - - - - - rust and packing - - - Warehousing < to sets of assembly>.
