(1) Assembly of integral sliding bearing
Integral sliding bearings, commonly known as bushings, are also the simplest form of sliding bearings. They are mainly assembled by press-in and hammering. Hot-filling is used for special occasions. Most bushings are made of copper or cast iron. Care should be taken when assembling with a wooden hammer or hammer pad. If the interference tolerance is large, press it with a press. The tilting must be prevented regardless of the knock-in or press-in. After assembly, the oil sump and oil hole should be in the required position.
For bearings that are deformed after assembly, the inner hole should be trimmed, the smaller size can be used for reamer cutting, and the larger size can be scraped. At the same time, pay attention to the matching clearance between the control and the shaft within the tolerance range. In order to prevent the rotation of the sleeve during operation, the contact surface of the sleeve and the box body is provided with a positioning pin or a riding screw. Since the hardness of the material of the box body and the sleeve material is not the same, it is easy to make the drill bit biased toward the soft material - the side, the solution is as follows: one is to punch the hard material while drilling, and the other is to use a short drill bit to Increase the rigidity of the drill bit when drilling.
(2) Assembly of split bearings
Split bearing, also known as split bearing, has the characteristics of simple structure, convenient adjustment and disassembly, two bushings on the bearing bush, and a reasonable gap between the joints.
