How to judge the quality of bearings by appearance

How to judge the quality of bearings by appearance

Bearings not only in a variety of mechanical equipment has a wide range of use, the effectiveness of the vehicle wheel is also very large, the key or so that it can be all normal operation, so how to distinguish the quality of the bearing from the appearance of the merits of it:

Two installation methods of deep groove ball bearings

Two installation methods of deep groove ball bearings

Press fit: when the inner hole of the bearing is fit with the shaft and the outer side is loosely fit with the bearing seat hole, the bearing can be pressed on the shaft with a punching machine, and then the shaft equipped with the bearing is installed into the bearing seat hole together. during the press fit period, a soft metal composite assembly sleeve (copper or high carbon steel) is placed on the end surface of the bearing inner hole, the outer side of the bearing is firmly matched with the hole of the bearing seat. The inner hole and the shaft are loosely matched with each other. The bearing can be pressed into the bearing seat hole first, and then the diameter of the installation sleeve specification should be slightly lower than the diameter of the bearing seat hole.

How to remove and install the outer spherical bearing?

How to remove and install the outer spherical bearing?

The inner ring of the spherical bearing is fixed on the shaft through the eccentric sleeve, and the inner hexagon screw on the eccentric sleeve plays a fastening role. In the maintenance process, many operators do not know how to disassemble such bearings, so it is necessary to introduce the technical points and precautions for disassembly and assembly of outer spherical bearings.

Functional characteristics of tapered roller bearings

Functional characteristics of tapered roller bearings

The type code of tapered roller bearing is 30000[5], and the tapered roller bearing is a separate bearing. Generally speaking, especially in the size range involved in GB/T307.1-94 "Rolling Bearing Tolerances", the outer ring and inner assembly of tapered roller bearings are 100% interchangeable.

What are the classification of spherical bearings?

What are the classification of spherical bearings?

Top wire outer spherical ball bearing code: UC200 series (light series), UC300 series (heavy duty series), deformation products UB(SB)200 series. If the use environment is suitable for small environments, generally choose the UC200 series, and vice versa. Then choose UC300 series. Usually there are two top wire on the outer spherical ball bearing, the included angle is 120 °. Its characteristic is that when it is matched with the shaft, it uses the top wire to support the shaft to play a fixed role, but its matching environment requires a smaller oscillation. This kind of spherical ball bearing is more common, widely used in textile machinery, ceramic machinery and other manufacturing industries.

Inspection after bearing installation

Inspection after bearing installation

Whether the bearing is installed correctly or not has a direct impact on its life and the accuracy of the host. If the installation is improper, the bearing not only has vibration, high noise, low accuracy, large temperature rise, but also has the danger of being stuck and burned; on the contrary, good installation can not only ensure the accuracy, but also greatly extend the life. Therefore, after the bearing is installed, it must be inspected.
