High-temperature bearings work efficiently, all depends on the choice of reasonable

Author:

In many cases, the shaft diameter or shaft diameter is based on the design of the machinery or its design limitations and impact, so the choice of bearing type and size of the bearing diameter decision, the main size of the bearing table are based on the international standard size and compilation of the size of the inner diameter.

Work, if you want to choose the right high-temperature bearings need to master the correct selection elements.

1. Size limitations

(1) Usually high temperature bearings can be installed in the space is limited.

In many cases, the shaft diameter or shaft diameter is based on the design of the machinery or its design limitations and impact, so the bearing type and size selection is the bearing diameter decision, the main size of the bearing table are based on the international standard size and compilation of the inner diameter.

(2) high temperature bearing load, the load applied to the bearing, its nature, size, direction is variable.

Usually, the rated basic load in the size of the table are shown. But the axial load and radial load, etc., is also an important factor in the selection of suitable bearings. When the size of ball and needle roller bearings are commensurate, needle roller bearings usually have a higher load capacity and withstand greater vibration and shock load.

2.Rotation speed

Rotational speed is based on high temperature bearing type, size, precision, cage type, load, lubrication, and cooling method and other factors to determine. Bearing table lists the scale precision bearings in oil lubrication and grease lubrication speed. Usually, deep groove ball bearings, self-aligning ball bearings and cylindrical roller bearings are suitable for high-speed operation.

3.Tolerance

The dimensional accuracy and rotational accuracy of high temperature bearings are according to ISO and JIS standards. For the requirement of high precision and high speed operation of machinery, it is recommended to use 5 or more precision bearings, deep groove ball bearings, centripetal thrust ball bearings or cylindrical roller bearings are suitable for high precision machinery.

4.Rigidity

(1) when the bearing's dynamic elastic body and raceway contact surface is pressurized, will produce elastic deformation. Some machines need to reduce the elastic deformation. Roller bearings than ball bearings produce less elastic deformation, in some cases bearings to apply preload to increase rigidity.

(2) This procedure is usually used for deep groove ball bearings, centripetal thrust ball bearings and tapered roller bearings where offset of the inner and outer rings, shaft bending, changes in the tolerance of the shaft or the bearing box, and mating errors can lead to eccentricity of the inner and outer rings.

(3) In order to prevent the eccentricity angle is too large, self-aligning ball bearings, self-aligning roller bearings, or self-aligning bearing seat is a better choice.

(4) voice frequency and torque, dynamic bearings are based on high-precision scale production manufacturing, so the voice and torque is small.

(5) deep groove ball bearings, and cylindrical roller bearings for low voice, low torque have special requirements for the occasion.

5.Mounting and dismounting

(1) Some applications need to be often disassembled and mounted to ensure that the inspection and maintenance can be carried out.

(2) The inner and outer rings can be mounted separately bearings such as:

Cylindrical bearings, needle roller bearings, and tapered bearings are very suitable for this application. Tapered hole type self-aligning ball bearings and self-aligning roller bearings with the help of bushings also simplify the mounting procedure.
