Jiaxing bearing small make up to introduce reducer bearing common problem for you

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. Reducer is a kind of rotating equipment, bearing rotates the device plays a very important role, therefore, when use of the gearbox, the installation of the bearing, the test is very important. In use process, speed reducer bearing some common problems and relationship problems, the author according to the understanding of the knowledge of bearing, reducer bearing some of the common problems related to the following share, hope to be of help. 1, why is thrust bearing clearance, and expansion gap? A metal material has the nature of the heat bilges cold shrink, when shaft under the working conditions at different temperature, axis length and diameter will change too. So in order to ensure the formation pressure of oil film, thrust bearing must have thrust clearance. B in order to ensure the shaft in the process of inflation, not impeded or restricted and produce a lot of stress, the bearing damage, must leave expansion gap. 2, how to use the method of measurement of lead wire split bearing cover and the top of the bearing clearance? A close to the bolt hole on surface of the bearing and the bearing cover combination and bearing lead wire is placed at the top of the arc length direction. B good cover, diagonal evenly tighten bolts. Remove bearing cover with outside micrometer measuring the thickness of lead wire, respectively. C will lead wire average thickness minus the bearing pedestal bearing outer ring plane average thickness, the difference is positive for clearance, namely negative is the tension force. 3, bearing oil level too low or too high what harm is there? A oil level is too high, can make the oil ring motion resistance increase skid or stopped, the mutual friction oil molecules can make the bearing temperature, oil and increase the clearance between oil leak of the friction power loss. B oil level is too low, can make the bearing of the ball or oil band can't afford to oil, cannot get cause bearing lubrication and make temperature, bearing burn out. 4, rotating machinery is the cause of high bearing temperature? A low oil level, lack of oil or without oil. B oil level is too high, too much oil. Oil is unqualified or worse (c Oil containing impurities) 。 D cooling water shortage or disruption. E oil ring with no oil or not. F bearing defective or damaged. G equipment vibration.
