Why use spherical roller bearings in wheel bearings

wallpapers Industry 2020-10-27

The wheel equipment of the industrial furnace heating furnace. In this example, the furnace only refers to steel forgings. The number of heating furnaces and annealing furnaces is a car-type furnace, so each car has multiple wheel equipment. This article starts with a two-dimensional drawing wheel and a three-dimensional model, discusses and understands:

The bearing in the wheel is a spherical roller bearing

Why use spherical roller bearings in wheel bearings? Do not use radial bearings, deep groove ball bearings?

During the traveling of the first car, the wheel speed was slow, about 6 or 7 meters per minute. Relatively speaking, the bearing speed was relatively slow.

The second car has no side wheels and single side wheels. The structural design of a single-sided wheel consists of a single-sided convex edge and an angle iron groove on the track. The unique feature of the spherical roller bearing is that the road surface is uneven, smooth and blocked when the small car is running normally. The self-aligning bearing has two rows of symmetrical spherical rollers, the outer ring has an ordinary spherical roller table, and the inner ring has two roller tables with a certain inclination with the bearing shaft, which has a good effect on the centering, so when the shaft is bent Or when the installation is uneven, the bearing can still be used normally.

The third type of spherical roller bearings can be checked and the price is relatively cheap.

Article 4 Spherical roller bearings: In addition to radial loads, spherical roller bearings also bear bidirectional axial loads.

2. Basic knowledge of bearing radial force and axial force elongation

Bearing The difference between the axial load and the radial load of the bearing. The axis refers to the central axis, and the diameter is the diameter. Spherical roller bearings: In addition to bearing radial loads, they also bear bidirectional axial loads.

3. Three-dimensional drawing of wheel axle and spherical roller bearing equipment

Using SolidWorks software, a three-dimensional model of the wheel of the trolley heating furnace was established. I want to give a brief description of this composition. The wheel is on the outside with holes for bearings, shafts and spacers in the middle. It consists of two spherical roller bearings. A spacer is used between the bearing and the bearing. Oil is added to the bearing of the wheel. The middle of the shaft is drilled to half the distance. The radial shaft is drilled. The outer oil cup is used for oil filling.
