Slewing bearing installation steps

Slewing bearings are a key component in the machinery industry, capable of withstanding combined loads, and are mainly used to carry and rotate various machine components. Its advantages include high load-bearing capacity, low energy consumption and high speed. Commonly found in gearboxes, drivelines and machine tools, slewing bearings are widely used and are known as the “joints of the machine”, providing efficient transmission and precise motion control. Choosing the right slewing bearing can help improve the performance and reliability of machinery and equipment.

Before the application of slewing bearings, the installation is also to ensure the subsequent normal operation of a major key, so a full understanding of the installation steps is also very necessary. Here we look at the installation of slewing bearings of several steps.

1. Before installing the slewing bearing, we should carry out a comprehensive inspection of the equipment to ensure that the equipment is in good condition. First of all, we have to check the host mounting surface to ensure that the supporting parts should have sufficient strength, the motor and the slewing bearing connected to the size of the various parts of the matching degree and flexibility.

2. In the process of subassembly installation and combination installation of the slewing bearing, it should be carefully and carefully protected to prevent damage. When installing the slewing bearing, put the slewing bearing horizontally on the installation base platform, check the position of the soft belt (generally labeled S), and put the soft belt and the blocking position in the non-load area or light load area. With a ruler to see the slewing bearing plane and the installation of the foundation plane whether there is a gap, if there is a large gap to prove that the installation of the foundation is not good flatness, if the conditions allow should be reworked to install the foundation, if the conditions do not allow, can be used in the gap at the method of eliminating the gap by using a pad of copper.

3. If the installation of the teeth of the slewing bearing needs to adjust the tooth side clearance, the correct tooth side clearance is very important to find the tooth high point (top of the tooth green paint or blue paint) position, can be used to measure the adjustment of the slewing bearing and pinion tooth side clearance, the general value of the side clearance adjusted to (0.03-0.04) times the modulus, adjusted the tooth side clearance, after manually rotating the slewing bearing at least one turn to verify that the teeth mesh without the phenomenon of hysteresis, and then install the bolt! According to 180 ° direction symmetrical continuous tightening, after checking to ensure that all the bolts on the circumference according to the required torque tightening.

4. After all the installation bolts are tightened, should promptly remove the size of the gears between, slewing bearing on and around the debris, and check the adjacent parts, to ensure that the slewing bearing rotation will not interfere with it, and then between the gears injected with lubricating grease, turn on the equipment pointing to rotate slowly for a few rounds, carefully check the slewing bearing running smoothly, the size of the gears mesh properly, there is no abnormal noise and stagnation phenomenon.

Slewing bearing installation directly affects the operating efficiency and stability of the equipment, so the installation process to ensure safety and accuracy as far as possible, so that the subsequent production operation can be carried out normally.
