Integral Radial Sliding Bearing

Integral Radial Sliding Bearing is composed of bearing seat and integral bushing. The bearing seat is provided with a threaded hole for installing the lubricating oil cup. An oil hole is formed on the shaft sleeve and an oil groove is formed on the inner surface of the shaft sleeve. The advantages of this kind of bearing are simple structure and low cost. Its disadvantage is that after the bushing is worn, the bearing clearance cannot be adjusted; in addition, it can only be assembled and disassembled from the end of the journal, which is very inconvenient or even impossible for a shaft with a large mass or a shaft with an intermediate journal. Therefore, this kind of bearing is mostly used in low-speed, light-load or intermittent machines.

Split radial sliding bearing Split sliding bearing consists of bearing seat, bearing cover, split bearing bush and double-ended stud. The split surface is often made in a stepped shape to align and prevent lateral displacement. There are threaded holes on the upper part of the bearing cover to install the oil cup. The bearing pad is also split, and the load is usually carried by the lower bearing pad. In order to save precious metals or other needs, a layer of bearing lining is often cast on the inner surface of the bearing bush. An oil groove is set in the non-load bearing area of u200bu200bthe inner wall of the bearing shell, and the lubricating oil flows into the bearing gap through the oil hole and the oil groove. The bearing split plane is preferably approximately perpendicular to the load direction, and most bearing split planes are horizontal (and some are inclined). This kind of bearing is easy to assemble and disassemble, and after the bearing bush is worn, the bearing clearance can be adjusted by reducing the thickness of the shim at the split surface.

Self-aligning radial sliding bearing

The ratio of the bearing width to the shaft diameter (B/d) is called the width-diameter ratio. For bearings with B/d>1.5, self-aligning bearings can be used. Its characteristics: the outer surface of the bearing pad is made into a spherical shape, which matches the spherical inner surface of the bearing cap and the bearing seat, and the bearing pad can be automatically adjusted to adapt to the shaft diameter in The deflection that occurs when the shaft is bent.
