Equipment used in mining vibration machinery, vibrating screen machinery, and vibration motors.
Vibrating screen bearings are mostly used in mining vibration machinery, vibrating screen machinery, and vibration motors. They are one of the most critical components of such equipment.
Bearing introduction
Vibrating screen bearings are mostly used in mining vibration machinery, vibrating screen machinery, and vibration motors. They are one of the most critical components of such equipment. The working conditions of this bearing are very harsh. Not only are the environment humid, there are many dust particles, the rotation speed is high, the temperature is high, but there is also strong vibration and impact, resulting in a very heavy workload. The bearing has strong load-bearing capacity, good impact resistance, high reliability, good lubrication performance, and can overcome the deflection deformation of the shaft.
Features
1. Vibrating screen bearings are generally symmetrical spherical rollers and cylindrical rollers;
2. Generally speaking, the dimensional tolerance is P6 and the running tolerance is P5. The tolerances are indeed fixed, but they are divided into imperial and metric systems;
3. Due to the high heat generation, a large clearance was chosen. However, this clearance can be calculated mainly by considering the original clearance, tolerance fit and temperature rise.
4. The application requirements of vibrating screen bearings are very high, and ordinary bearing steel materials are not suitable. The cage is machined brass and guided by the outer ring to accommodate eccentric loads!
Application areas
1. Mainly used in mining vibration machinery and equipment, vibrating screen machinery, and vibration motors;
2. Rivet machines, rock drills, pneumatic shovels and other pneumatic tools;
3. Electric drills, electric saws, forestry chain saws, grinders, polishers, grinders, road maintenance tamping machines and other power tools;
4. Diesel locomotives, ships, motorcycles and other transportation vehicles;
5. Agricultural machinery such as tractors, harvesters, and threshers;
Spherical roller bearing
Spherical roller bearings are bearings in which drum-shaped rollers are assembled between an inner ring with two raceways and an outer ring with a spherical raceway.
Divided into: cylindrical inner hole and conical inner hole.
Spherical roller bearings have two rows of rollers, which mainly bear radial loads and can also bear axial loads in any direction. It has high radial load capacity and is especially suitable for working under heavy load or vibration load, but it cannot bear pure axial load. The outer ring raceway of this type of bearing is spherical, so its alignment performance is good and it can compensate for coaxiality errors.
Check before installation
(1) Clean bearings and bearing related parts;
(2) Check the dimensions and finishing conditions of related parts;
