Jiaxing bearing factory: high-speed bearing installation should pay special attention to the problem

【 Jiaxing bearing group co. , LTD. ) Jiaxing bearing group sales co. , LTD was established in jiaxing bearing spot sales window, specializing in HRB bearings, have stock 50 million yuan, in terms of production design and related mechanical application has a wealth of technical experience, today we are together and we learn the high-speed bearing installation should pay special attention to the problem. High-speed bearing has two characteristics, one is high precision, is a high temperature resistant. So the high-speed bearing should be in accordance with the requirements for high precision bearing installation, and according to the high temperature bearings to install. So when installing high-speed bearing considering the coordination and bearing clearance. When installing a high-speed bearing should consider 2 points: hardness change caused by temperature rise; Caused by high speed rotating centrifugal force system and shape changes! To ensure the bearing raceway deformation after the installation is small, the amount of interference interference fit can't get too big, and under the high speed centrifugal force and high temperature thermal expansion, or on the surface of the offset with the normal pressure. Or make the matching surface relaxation, thus interference quantity must under the premise of considering these two factors determine prudently, effectively under the constant velocity of the amount of interference for high-speed bearing may be invalid. Install the necessary condition 1. Assembly site should be kept clean, no dust. 2. To avoid bearing from dust, moisture and contaminants pollutants have a bad effect on the running and service life of bearing. 3. Check the bearing hole and the shaft with the following: geometry and dimensional accuracy, and cleanliness. 4. For bearing ring mating surface coated with a little oil or a little fat. 5. To ensure that the shaft and bearing hole with a 10-15 degrees lead chamfer. 6. Don't be cool bearing: condensation of water can lead to bearing and the bearing of mating surface rust. 7. After installation: for bearing loading lubricants, check whether the bearing configuration is working properly.
