Rocking chair bearing classification

Sliding bearing

Sliding bearings are not divided into inner and outer rings and have no rolling elements, and are generally made of wear-resistant materials. Commonly used for low speed, heavy load and lubrication, and mechanical rotation of difficult maintenance.

Joint bearing

The sliding contact surface of the joint bearing is spherical, and is mainly suitable for oscillating motion, tilting motion and rotational motion.

Rolling bearing

Rolling bearings are divided into radial bearings and thrust bearings according to the load direction or nominal contact angle they can withstand. The radial contact bearing is a radial bearing with a nominal contact angle of 0, and the radial angular contact bearing is a radial bearing with a nominal contact angle greater than 0 to 45. The axial contact bearing is a thrust bearing with a nominal contact angle of 90, and the thrust angular contact bearing is a thrust bearing with a nominal contact angle greater than 45 but less than 90.

The rocking chair bearing can be divided into ball bearings and roller bearings according to the shape of the rolling elements. Roller bearings are divided into roller types: cylindrical roller bearings, needle roller bearings, tapered roller bearings and spherical roller bearings.

Rocking chair bearing is divided into self-aligning bearings according to whether it can be adjusted during operation----the raceway is spherical, and can adapt to the angular deviation and angular movement between the two raceway shafts and the non-aligning bearings ( Rigid bearing)----bearing that can offset the axial angle deviation between the raceways.

The rocking chair bearing is divided into single row bearings, double row bearings and multi-row bearings according to the number of rows of rolling elements.

The rocking chair bearing is divided into separable bearings and non-separable bearings according to whether the components (ferrules) can be separated.

According to its structural shape (with or without filling grooves, the presence or absence of inner and outer rings and the shape of the ferrule, the structure of the ribs, and even the presence or absence of cages), the rocking chair bearing can be divided into various structural types.

Rocking chair bearing is divided into miniature bearing (<26mm), small bearing (28-55mm), medium and small bearing (60-115), medium and large bearing (120-190mm), large bearing (200-430mm) according to its outer diameter. ) and extra large bearings (>440mm).

In fact, rocking chair bearing still has a lot of other knowledge, not listed here. In our daily life, we must have some understanding of some daily electrical appliances, understand the working principle, and understand the use of skills, so that after some problems in the electrical appliances can be solved faster, so as to facilitate our lives and improve our quality of life.
