Drawn cup needle roller bearing is a specially designed rolling bearing that has some unique structural characteristics. This type of bearing typically consists of a stamped outer ring and a needle roller, used to support and transmit rotational or oscillating motion. So what is the working principle of the drawn cup needle roller bearing commonly seen in daily life? Below is a detailed introduction to this issue!
Drawn cup needle roller bearing is a type of bearing commonly used in high-speed motion and high load conditions, especially suitable for applications such as automotive engines, transmissions, and transmission systems. Its working principle involves the structure of bearings and the rolling principle.
The working principle of the drawn cup needle roller bearing is as follows:
Structure: Stamped outer ring needle roller bearing consists of outer ring, inner ring, needle roller, cage, etc. The precise design and manufacturing of the rolling needle and inner and outer rings ensure the high precision and high load bearing capacity of the bearing.
Rolling principle: The drawn cup needle roller bearing adopts the rolling principle, which reduces friction and contact with the bearing surface through the rolling motion of the needle. The rolling needle rolls between the inner and outer rings to support the rotational motion on the shaft.
Distributed load: Needle roller bearings disperse the load through the rolling of the needles, thereby reducing friction and wear. This enables needle roller bearings to withstand greater loads and higher speeds.
Reducing friction: Rolling friction is much smaller than sliding friction, and the rolling motion of the needle roller reduces the internal friction of the bearing, thereby reducing energy loss and heat generation.
Self lubrication: Drawn cup needle roller bearings are usually coated with lubricating grease on the inner ring and needle rollers, which helps reduce friction and extend bearing life.
High speed motion: Drawn cup needle roller bearings are suitable for high-speed motion because their rolling characteristics reduce friction and heat generation, thereby reducing the problems that bearings may face during high-speed motion.
Drawn cup needle roller bearings reduce friction, disperse loads, and achieve high-speed motion and high load bearing capacity through the rolling principle. This type of bearing is widely used in various mechanical equipment, especially in fields that require high precision, high speed, and high reliability.
