1. Removal of outer ringDismantle the outer ring of interference fit, set several screws for extruding the outer ring screw on the 8-shaped side sheet of the shell in advance, tighten the screw evenly on one side, and disassemble at the same time. These screw holes are usually covered with blind plugs, tapered roller bearings and other separate bearings. Several notches are set on the housing shoulder, and the circui...
More details1、 Classification of benchmarksAccording to the use basis: 1. Design basis. The point, line and surface used to determine the position of the part in the 6014 cross shaft bushing machine are called design datum. 2. Process benchmark. The selected datum for processing, measuring and inspection of parts. According to the form of datum: ① datum point, a point on the part surface. ② Datum line, the axis of the turning su...
More detailsBearing clearance is also called bearing clearance. The so-called bearing clearance refers to the amount of movement when the bearing is not installed on the shaft or bearing box, fixes one side of its inner ring or outer ring, and then moves the side whose bearing clearance is not fixed radially or axially. According to the moving direction, the PTFE soft belt bearing can be divided into radial clearance and axial c...
More detailsSliding bearings are widely used, such as textile machines, printing presses, automobiles, tobacco machinery, micro motors, motorcycles, agricultural and forestry machinery, etc. Sliding bearings also have their own characteristics and advantages.1. It can reduce vibration and noise of machinery, prevent pollution and improve working conditions.2. It has an appropriate amount of elastic-plastic, can distribute the st...
More detailsComposite bimetallic bearing is one of oil-free lubrication bearings. The product is made of high-quality low-carbon steel back as the base, sintered lead tin bronze alloy on the surface, and rolled into a bimetallic strip of copper and steel after several times of high temperature sintering and compact rolling. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, stron...
More detailsWhen we use sliding bearings, we often find that this sliding bearing is different from the original. Let's take a look at why this is now.When the sliding bearing is in operation, friction will occur due to the contact between the journal and the bearing bush, which will cause the surface to heat up, wear and even "seize". Therefore, when designing the bearing, the sliding bearing material with good friction reducti...
