Tapered Roller Bearings and Profile Features and Precautions: tapered roller bearings to achieve its special mechanical design of the internal structure of small and lightweight. Lubricant life, household appliances usually maintenance-free bearing grease sealed bearings. Lower bearing good lubrication of the total operating time is called bearing life.
Tapered Roller Bearings Introduction and characteristics and precautions:
Tapered roller bearings to achieve its special mechanical design of the internal structure of small and lightweight. Lubricant life, household appliances usually maintenance-free bearing grease sealed bearings. Lower bearing good lubrication of the total operating time is called bearing life.
Despite bearing lubrication need only trace amounts of lubricant, poor bearing lubrication, a unique mechanical equipment to do precision machining, but after running for a long time due to the deterioration and leakage of grease, so that the bearing failure. Tapered roller bearings are usually separated type, that is with roller cone and adhere to the inner components of the inner frame assembly can be formed with a conical cup (outer ring) separate devices.
Tapered roller bearings are widely used in automotive, mill, mining, metallurgy, plastics machinery and other industries.
Tapered roller bearings are rolling element elongated needle roller bearing rotation. Compared with ball bearings, needle roller bearings have a characteristic low-profile and high load capacity. Needle roller bearings can be used to contribute to the overall simplicity of the machine, saving space and so on. It is widely used in industries of vehicles, motorcycles, printing machinery, industrial robots and construction equipment.
High bearing temperatures reasons: mechanism assembly too tight (the space is not sufficient) IKO bearing assembly too tight; bearing ring is rotated on the shaft or housing; lubricating oil or undesirable quality deterioration, lubricating oil viscosity is too high; load is too large; cam maintain Gulu frame or body broken and so on.
Compared with the general mechanical parts, high precision rolling bearing, and therefore accordingly should be careful when using.
1. Develop a job specification bearings.
2. If using a carefully careless use of the bearing with a strong impact, will appear bearing scars, indentation, fracture and other injuries.
3. Users should be familiar bearings.
4. Note the bearings rust, prevent the use in humid places, but also not to sweat stained, should wear gloves.
5. Use the right tools.
6. Clean the bearing and stick around.
Long cylindrical roller bearings, bearing similar characteristics with the use of needle roller bearings, but radial cross-section larger than the size of the bearing needle roller bearings, and therefore, can accept large radial loads. Can only accept pure radial load and can not limit the axial displacement of the bearing, the bearing means, it does not allow the axis of the inner ring and outer ring axis angle error occurred.
Long cylindrical roller bearings and needle roller bearings needle whose length to diameter ratio (aspect ratio) is greater than the difference that 3 long cylindrical roller bearing roller diameter greater than 5 mm. Thus, the structural form, the long cylindrical roller bearings and needle roller bearings have many of the same structure. Long cylindrical roller bearings with needle bearing the same.
Single row tapered roller bearings in the device only after there is clearance, and another in the opposite direction to adjust the positioning of the bearing can only be determined after.
Adhere to frame
Tapered roller bearings generally use steel stamping, box-type cage, but the size is larger, also uses machined solid pillars adhere to frame.
1. When the bearing outer diameter D≤650mm, the use of steel stamping cage, adhere to frame post-code not sign
2. When the bearing outer diameter D> 650mm, using steel solid pillars adhere to frame, adhere to frame a code does not post signs
