INA roller bearing fixing method INA roller bearings are fixed parts in machinery. The working performance of INA roller bearings depends mostly on their material properties. Low-alloy, high-purity integrally quenched chrome steel is usually used as the material for manufacturing INA bearing rings and rolling elements. For INA bearings subjected to high impact loads and alternating bending stress, using carburized steel.
INA roller bearings are divided into inner and outer rings. How is it fixed? INA roller bearing is fixed with lock nut. The inner circle of INA roller bearing is axially fixed by the shoulder and lock nut. It has a lock washer to prevent loosening, which is safe and reliable. The INA roller bearing's sleeve fixation depends on the radial size of the inner bore of the adapter sleeve being compressed and clamped on the shaft to achieve the axial fixation of the INA roller bearing's inner ring. INA roller bearing shaft shoulder fixing INA roller carrying inner circle relies on the shaft shoulder and interference to achieve axial fixation. Suitable for support structures with fixed ends.
The INA roller bearing is fixed by the retaining ring of the INA roller bearing. The inner circle of the INA roller bearing is axially fixed by the shoulder and the lock nut and can withstand small axial load in both directions. The INA bearing's end face washer is set on the INA bearing's inner ring by the shoulder and shaft end retaining ring to achieve axial fixation. The shaft end retaining ring is fixed at the shaft end with screws, and the fixing screws should have anti-loosening devices.
INA roller bearings are widely used mechanical bearings. Its function is to support the shaft and its parts under the condition of ensuring sufficient life of the bearing, and to make relative rotation and swing with the machine base, to reduce the friction between the rotating pair as much as possible to obtain higher transmission effectiveness.
Commonly used INA roller bearings have formulated national standards, which are designed using the principle of rolling friction and are standard parts produced in batches by specialized factories. In mechanical design, it is only necessary to select the appropriate INA roller bearing type and model for the combined structure design according to the working conditions.
Compared with sliding bearings, INA roller bearings have the following advantages: low starting friction torque, low power loss, and higher efficiency than INA roller bearings. The application design is simple, the product has been standardized, and professional manufacturers mass-produce it. It has excellent interchangeability and versatility. Most types of bearings can support both radial and axial loads with small axial dimensions. The range of load, speed, and the working temperature is full, and small changes in working conditions have little effect on bearing performance. Easy to lubricate, maintain, and maintain.
INA roller bearings also have the following disadvantages: short life when working under high speed and heavy load conditions. Most INA roller bearings have larger radial dimensions. High vibration and noise. INA imported bearing structure: INA roller bearings are generally composed of inner ring, outer ring, rolling body, and cage. The inner circle is installed on the shaft journal, and the fit is tight. The outer ring is installed in the bearing hole of the base or the part, and the fit is usually loose. There are raceway on the inner and outer rings. When the inner and outer rings are relatively rotated, the rolling elements will roll along the raceways. A rolling part is a rolling element that realizes rolling friction. In addition to the rotation, it also revolves around an axis. Shapes are spherical, cylindrical, cone-cylindrical, needle, drum, etc. The function of the cage is to separate the rolling elements evenly.
To meet market-specific requirements, some bearings can have no inner ring or outer ring or with a dust-proof, seal ring, and other structures. Standard materials: The materials of rolling elements and inner and outer rings require high hardness and contact fatigue strength, excellent abrasion resistance, and impact toughness. Generally made of chromium-containing alloy steel, commonly used materials are GCr15, GCr15SiMn, GCr6, GCr9, etc., and the hardness can reach HRC61-65 after heat treatment. Cages are usually stamped from low-carbon steel plates, and high-speed bearings are mostly made of non-ferrous metal or plastic enclosures.
