Industries
Construction machinery mainly includes excavators, bulldozers, tower cranes and other machinery. The bearings of construction machinery mainly include spherical roller bearings and cylindrical roller bearings.
Tower Crane
The working principle of a tower crane is that the hoisting machinery lifts or lifts and moves heavy objects through a lifting hook or other retrieval device. The working process of lifting machinery generally includes steps such as lifting, running, lowering, and returning to the original position. The lifting mechanism lifts the heavy object from the picking place through the picking device, displaces the heavy object through the running, turning, or luffing mechanism, and returns the heavy object to the original position after dropping the heavy object at the designated place. The upper end of the tower crane is divided into three parts: the balance arm, the boom, and the top of the tower. The top of the tower is connected to the two arms, and then a pull rod is installed on the upper end of the tower and the two arms respectively. The pull rod can make the arm stable and not fall. Secondly, it is equivalent to the principle of a lever when lifting things. As long as the two arms are balanced, they will not be lifted. Overturning the tower crane. Bearings are what connect these levers and make them work.
1. Spherical roller bearing used on the lifting mechanism; this type of bearing has a large load capacity, in addition to bearing radial load, the bearing can also bear axial load acting in both directions, and has better impact resistance, Generally speaking, the allowable working speed of spherical roller bearings is lower.
2. The tapered roller bearing used in the traction mechanism of the trolley can bear a larger axial load. The operating temperature of this bearing is lower, so it can meet the requirements of higher speed.
3. Deep groove ball bearing with the dust cover on one side used on the trolley;
4. Thrust ball bearingused on the hook
Excavator
An excavator is a special engineering vehicle that consists of a rotating platform, a large shovel, and a robotic arm. Generally, it travels on tracks or wheels. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. The working environment is relatively humid, dusty, muddy, the working environment is relatively harsh, and the requirements for bearings will be relatively high. Bearings in key parts of excavators mainly bear radial force, certain axial force, heavy load, and low speed, so larger double-row tapered roller bearings are generally selected. Or use cylindrical roller bearings with tapered roller bearings.
