Bimetal Bearing Raceway Noise In The How To Deal With

bimetal bearing raceway noise in the how to deal with
bimetal bearing raceway noise, sound is due to bimetal bearings change the raceway in the rolling corner of the rolling, comfort and smooth and continuous noise contact ball bimetal bearing species, only when the sound pressure level or tone, 1 Great absorption of attention.
In fact, the excitement of the sound of the sound of the acoustic energy of the roller is immeasurable, due to the normal situation, the high character sound of the bimetal bearing raceway 2 mill bimetal bearing 527 dB. This is the most exemplary load noise in radial bimetal bearings, which has the following exclusion.
The use of bimetal bearings uniform life, great care level, from the bimetal bearing to carry an extraordinary determination to absorb anti-corrosion coating. However, very few data must be created without diminishing. Due to compliance, downtime lofty joy, you may be eligible for housing and policy guidelines. Any practical meaning of the pad storage and removal of the removal of the test and installation are included. For all the dry ideas. Bimetal bearing lubrication to ensure poor performance. Check the lubricating oil pump complete, the pipeline flow spark specifications fuel tank to ensure adequate supply of oil. Lubricants are pickled without dirt, while in the appropriate range of the cursor, and follow the exact gear oil, the winter oil viscosity check after about 5 minutes to check the oil level within the category you may run the oil blunt, There is a need to take the level of compensation.
bimetal bearings are bearings that operate under sliding friction. bimetal bearings work smoothly, reliable, no noise. In the liquid lubrication conditions, the sliding surface is separated by lubricating oil without direct contact, but also can greatly reduce the friction loss and surface wear, the film also has a certain vibration absorption capacity. But start frictional resistance. The shaft is supported by the bearing part called the journal, and the part that matches the journal is called the bearing. The friction-reducing material layer cast on its inner surface in order to improve the frictional properties of the pad surface is called a bearing lining. Bushing and bearing lining materials are collectively referred to as bimetal bearing materials. bimetal bearing applications are generally in low speed, heavy load, high precision or intermittent working conditions.
1, bimetal bearing main features
Commonly used bimetal bearing materials are bearing alloy (also known as Babbit or white alloy), wear-resistant cast iron, copper and aluminum alloy, powder metallurgy materials, plastic, rubber, hardwood and carbon-graphite, polytetrafluoroethylene, Modified polyoxymethylene and so on.
2, bimetal bearing composition structure
Bimetal bearing work is the occurrence of sliding friction; rolling friction depends mainly on the size of the manufacturing accuracy; and bimetal bearing friction depends mainly on the size of the bearing sliding surface material. bimetal bearings are generally self-lubricating work surface; bimetal bearings in accordance with the material is divided into non-metallic bimetal bearings and metal bimetal bearings.
Non-metallic bimetal bearings are mainly plastic bearings, plastic bearings are generally made of better performance of engineering plastics; more professional manufacturers generally have engineering plastics self-lubricating modification technology, through the fiber, special lubricants, glass Beads and so on to the engineering plastics self-lubricating enhanced modification to achieve a certain performance, and then modified plastic through injection molding into self-lubricating plastic bearings.
Metal bimetal bearings are currently the most widely used three-layer composite bearings, these bearings are generally carbon steel plate for the substrate, through the sintering technology in the steel plate first sintered a layer of spherical copper powder, and then sintered on the copper layer About 0.03mm of PTFE lubricant; which is a layer of spherical copper powder in the middle of the main role is to enhance the bonding strength between the steel plate and PTFE, of course, at work also play a certain bearing and lubrication.
