32308Tapered roller bearings the role and characteristics of tapered
Tapered roller bearing is a kind of widely used rolling bearing, which has the advantages of large bearing capacity, abrasion resistance, high speed, and wide application range. Tapered roller bearings are widely used in mechanical transmission systems, especially in large mechanical equipment.
Two, tapered roller bearing as the fixed end of the shaft advantages and disadvantages
In mechanical transmission systems, the fixed end of the shaft needs to be stable and reliable to ensure transmission efficiency and shaft safety. Whether the tapered roller bearing can be used as the fixed end of the shaft alone is a problem that many mechanical engineers pay attention to. In fact, the shortcomings of tapered roller bearings as the fixed end of the shaft are obvious, mainly in the following aspects:
1. It is very easy to slip and deform.
2. Easy to produce axial deviation and runout.
3. The carrying capacity is relatively small.
Therefore, the use of tapered roller bearings alone as the fixed end of the shaft is not stable and reliable enough
In order to make the fixed end of the shaft more stable and reliable, it is necessary to adopt a more stable design, including the installation of thrust rings, internal and external coaxial aligning roller bearings or a combination of the two, in order to effectively solve the problems of axial deviation and sliding, so that the fixed end of the shaft is more stable and reliable.
