Spherical roller bearing clarification Spherical roller bearings between the inner ring with two raceways and the outer ring with a spherical race; bearings with drum rollers. The middle of the curvature of the raceway of the outer ring and the bearing Common in the middle; therefore, it has the same self-aligning function as the active self-aligning ball bearing. When the shaft and the outer casing are deflected; it can be actively adjusted; the shaft is not added. The spherical roller bearing can be accepted; the radial load and the two directions can be accepted. Axial load. Radial load can be large; suitable for heavy load, impact load conditions. The inner ring inner diameter is a tapered bore bearing; can be directly installed. Or use the adapter sleeve, open the cylinder device on the cylindrical shaft. The cage uses steel stamping cages, polyamide forming cages and copper alloy cages.
Spherical roller bearings can accept large radial loads; they can also accept a certain axial load. The outer ring raceways of this type of bearings are spherical in shape; therefore, they have a aligning function; when the shaft is subjected to bending or skewing, The middle line of the inner ring and the middle line of the outer ring are not inclined more than 1°~2. 5°; the bearing can still work.
The inner diameter of the spherical roller bearing has two kinds of cylindrical and conical shapes. The taper of the conical inner hole is 1:1 2 or 1:30. In order to strengthen the smooth function of the bearing; the annular oil groove and three are processed on the outer ring of the bearing. Uniform oil holes.
Spherical roller bearings are suitable for heavy loads and impact loads; they are widely used in metallurgy, rolling mills, mining, petroleum, paper, cement, sugar, etc. 32370 Spherical roller bearings have two rows of symmetrical spherical rollers that can be used outside. The concave spherical raceway of the circle is intentionally adjusted. This can compensate for the concentricity error caused by the tortuous deformation of the shaft and the bearing device. This bearing receives the radial load; the two-way axial load and its component load can be larger; Suitable for applications where heavy loads and shock loads are accepted at low and medium speeds.
Tapered roller bearings clarify that tapered roller bearings mainly accept radial-oriented radial and axial combined loads. Bearing bearing capacity depends on the raceway viewpoint of the outer ring; the larger the viewpoint, the greater the bearing capacity. This type of bearing is a separate type. Bearings; single-row, double-row and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing. The single-row tapered roller bearing clearance needs to be adjusted by the user during installation, and the double-row and four-row tapered roller bearing clearances have been The product is given according to user requirements when it leaves the factory; no user adjustment is required.
Tapered roller bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other occupations.
