Magnetic Motor Bearing Introduction

Almost all motor magnetic motors, so called magnetic motor bearings are considered motor bearings, magneto bearings is a gimmick , but the title is actually based on the deep groove ball bearings , bearing internal clearance , vibration, insulation make special provisions lubrication , clear environment only. The mall level deep groove ball bearing motor (magnetic motor bearings ) , in strict accordance with requirements of the motor class products manufacturing, testing, product won wide praise long-term users.

Deep groove ball bearings for high speed or high speed operation , and is very durable, without regular maintenance. This kind of bearing friction coefficient, high limiting speed, size range and diverse , used in precision instruments, low noise motors , automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used type of bearings . The main radial load , but also can withstand a certain amount of axial load.

Deep groove ball bearings are bearing the most common type . The basic model consists of a deep groove ball bearing outer ring, an inner ring, a set of balls and keep the structure into a deep groove ball bearing type code 6. Its structure is simple , easy to use , the production of the most popular , the most widely used class bearings.

Deep groove ball bearings are mainly used for pure radial load, but also to support radial and axial load . When the only pure radial load , the contact angle is zero. When the deep groove ball bearings with a larger radial clearance , with angular contact bearings can bear large axial load. Deep groove ball bearing friction coefficient is small , limit speed is also high, especially very high speed load conditions in the axial deep groove ball bearings Thrust ball bearings are more advantages .

Deep groove ball bearing structure is simple , easy to achieve compared with other types of manufacturing high precision , so easily into a series of high-volume , lower manufacturing costs , the use of very common . In addition to the basic type of deep groove ball bearings , there are a variety of structural variants , such as: deep groove ball bearings with dust cover ; deep groove ball bearings with rubber seals ; stopper groove deep groove ball bearings ; has installed ball gap large load capacity of deep groove ball bearings ; double row deep groove ball bearings.

Deep groove ball bearings are the most representative of rolling bearings , widely used. Suitable for high speed or high speed operation , and very durable, without regular maintenance. This kind of bearing friction coefficient is small , extreme high speed , simple structure, low cost, easy to achieve high manufacturing precision. Size range and diverse , used in precision instruments, low noise motors , automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used type of bearings . The main radial load , but also can withstand a certain amount of axial load.

When you select a larger axial radial clearance increased carrying capacity , subject to pure radial force when the contact angle is zero. The axial force, the contact angle is greater than zero. Commonly used stamping ribbon cage , machined solid cage, sometimes with nylon frame .

Deep groove ball bearings mounted on the shaft , the axial bearing clearance range , limit the two directions of axial displacement of shaft or housing , it can be positioned in the bi- axial . In addition , the class also have some bearing self-aligning capability , when compared to shell -hole tilt 2 'to 10' , still work , but has some influence on bearing life . Deep groove ball bearing cage mostly steel stamping ribbon cage , a large multi-use vehicles bearing metal solid cage.

Due to the limited capacity of self-aligning deep groove ball bearings , bearing installation requiring seat concentricity, concentricity not affect the operation of the balance, increased bearing stress , thus shortening the working life of the bearing . Deep groove ball bearings can only allow a small deflection angle , which is dependent upon the load size. Deep groove ball bearings can be used in fans, motors , machine tools, cement plants , power plants, transmission, instrumentation , electrical , household appliances , internal combustion engines , transport vehicles , textile machinery , agricultural machinery, construction machinery , construction machinery and other industries.

Note the use of :

Motor -class deep groove ball bearings are precision parts , thus requiring the use of fairly cautious attitude that change is the use of high-performance bearings , if used improperly, they can not achieve the expected performance results, and easy to bearing damage. Therefore , the use of bearings should note the following:

First, the bearing and the surrounding environment be kept clean , even invisible dust into the bearing smile , will increase the wear , noise and vibration of the bearing.

Second, when using the installer should carefully allowed powerful punch , does not allow a direct hit with a hammer bearing pressure is not allowed to pass through the rolling .

Third, the use of appropriate and accurate installation tools, to make use of special tools, try to avoid using things fabric and staple fiber and the like .

Fourth, to prevent corrosion of bearings , bearing direct hand when handling , to fully wash hands sweat , and coated with high-quality mineral oil before operation, during the rainy season and summer with particular attention to rust. However , in some special operating conditions , the bearing can be obtained in a longer life of traditional computing , in particular in the case of light load . These special operating conditions is that when the rolling surface ( track and rolling elements ) are effectively separated and limit pollutants may cause damage to the surface of a lubricant film . In fact, under ideal conditions , the so-called permanent bearing life is possible.

Motor level consists of a deep groove ball bearing outer ring, an inner ring , a ball , a group composed holder and two seals . From the dust effect , and can effectively prevent spillover bearing grease inside .
