Jiaxing bearing small make up to high temperature bearing noise limit speed emergency measures

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. If the selected bearing speed limit speed cannot satisfy the use requirement, can use some improved technology measures to improve, to achieve a satisfactory requirements. Such as improve the high temperature bearing tolerance level; Appropriate increase of clearance. Use special materials and the structure of the improved cage; Change the lubrication method, such as lubrication oil and gas, oil mist and spray; Improve the cooling condition, etc. ( 1) , bearing raceway groove sound sound and its control method is when bearing is running, the roller rolling on the surface of the raceway and a line of continuous sound, is unique to occur in all rolling bearings of the basic sound. The general high temperature bearing ring raceway is combined with other sounds. Bearing raceway is irregular, frequency above 1000 hz, its main frequency does not change with speed, but its total sound pressure level increases with speed to speed up. Raceway large bearings, the rolling sound of sound pressure level decrease with the increase of the viscosity; And high temperature bearing raceway sound small, the sound pressure level in the viscosity increases to about 20 was/s above, from decreased to increase somewhat. And the rigidity of the bearing, the greater the raceway of the lower the total sound pressure level. Such as radial clearance is too small, the total sound pressure level and race master frequency will increase sharply with the decrease of radial clearance. Control of raceway acoustic methods are: using low noise bearing is bearing waviness is very small, that is, carefully select and use conditions. Race often affect the mechanical noise, reduce the raceway can reduce the mechanical noise. ( 2) , the impact of the rolling element and its control method for larger models of cylindrical roller bearing or bearing under pure radial load speed, due to centrifugal force is lesser, roller in the rolling body will impact the load area or race and making noises. But with the increase of rotational speed, the noise will disappear. Control method of rolling body impact sound: decrease the radial clearance, use with reasonable structure and material with kindliness high temperature bearing cage. ( 3) , bearing rolling rolling rolling rolling noise and its control method is bearing in the harsh metal can occur in all occasions, mostly happens in large type bearing grease lubrication, and in the base oil performance degradation occurred more often in grease, almost does not occur when oil lubrication. In addition, more easily occur during the winter, when under pure radial load, the radial clearance prone to big occasions, and with different size, easy to happen in a certain speed range, both continuous and intermittent. External ring raceway take special processing method can prevent the occurrence of roll ring, can choose this kind of high temperature bearing, if necessary or appropriate to reduce bearing radial clearance, the use of high performance grease and improve to suit the bearing parts of rigidity.
