What Are The Bearings In The Carnival Fair Rides?
(1) Carnival Fair Rides Sliding bearings. Sliding bearings can be divided into radial sliding bearings (supporting radial loads), thrust sliding bearings (supporting axial loads) and radial thrust sliding bearings (supporting radial loads at the same time) according to the direction of the load they can bear. and axial load).
Sliding bearings can be divided into dry friction bearings, incomplete oil film bearings (in the state of boundary friction and mixed friction) and fluid film bearings (in the state of fluid friction) according to the friction state between their sliding surfaces.
According to the different formation principles of the fluid film in the fluid film bearing, it can be divided into fluid (liquid, gas) dynamic pressure bearing and hydrostatic pressure bearing.Carnival Fair Rides Application range:amusement park、playground、theme park.
(2)Carnival Fair Rides Rolling bearings Rolling bearings rely on the rolling contact between components to bear the load. Compared with sliding bearings, rolling bearings have the advantages of low frictional resistance, high efficiency, easy starting, and simple lubrication, and are widely used in modern machines.
According to the direction of the main load that the bearing can bear, rolling bearings can be divided into two categories: radial bearings and thrust bearings. Bearings whose main load is radial load are called radial bearings; those whose main load is axial load are called thrust bearings.
The basic structure of rolling bearing is shown in Figure 2-97, which consists of inner ring, outer ring, rolling body, cage and other parts. The inner ring is installed on the journal and the outer ring is installed in the bearing seat hole.
Usually the outer ring is fixed, and the inner ring rotates with the shaft, but it can also be used for occasions where the inner ring does not move while the outer ring rotates, or the inner and outer rings rotate at the same time.
The rolling elements are evenly distributed between the inner and outer ring raceways, and the difference in shape, number and size has a great influence on the bearing capacity and limit speed of the rolling bearing.
