What do you know about tapered roller bearings?

Tapered roller bearing is a removable bearing, and the inner ring and outer ring can be separated. Therefore, during installation, the arrangement of rolling elements of inner ring cage can be adjusted through the pressure shaft, and the outer ring can be installed separately in the bearing seat hole.

What are the commonly used materials for tapered roller bearings?

The hardness of the roller and the materials used for the rolling ring shall be high, and the materials used for the bearing shall have good impact resistance and contact strength. It is generally made of chromium containing alloy steel. Common materials include GCr15, GCr15SiMn, gcr6, gcr9, etc. the hardness after heat treatment can reach hrc61-65. The cage is usually punched with low-carbon steel plate, and the high-speed bearing is usually composed of non-ferrous metal (such as brass) or plastic cage.

What is the relevant information of tapered roller bearings?

The single row tapered roller bearing comprises an outer ring and a group of inner rings, and the inner ring and a group of tapered rollers are encapsulated in a basket. The outer ring can be separated from the inner ring. According to the dimension standard of ISO tapered roller bearing, the outer ring or inner ring of each standard type of tapered roller bearing shall reach international performance. Swap. This means that in addition to the overall dimensions and tolerances, the outer ring of the same model shall also comply with the provisions of iso492 (gb307), and the cone angle and cone diameter of the inner ring components shall also comply with the relevant interchangeability. Rules and regulations.

Generally, the cone angle of the outer race of single row tapered roller bearing is between 10 ° ~ 19 °, which can absorb the combined action of axial load and radial load at the same time. The larger the cone angle, the greater the ability to bear axial load. Large cone angle bearing, zip code plus B, with cone angle between 25 ° and 29 °, can bear large axial load. In addition, for single row tapered roller bearings, the clearance dimension can be adjusted during installation.

What are the design features of tapered roller bearings?

The design of tapered roller bearing has the following characteristics;

(1) They are removable bearings, i.e., the inner ring with rolling elements forms an assembly that can be installed separately on the outer ring.

(2) The axial bearing capacity of the bearing largely depends on the contact angle, which corresponds to the angle of the outer ring.

(3) Tapered roller bearing can bear high-level combined load (axial and radial), which has obvious advantages compared with other bearings.
