The slewing ring is widely used in machinery. Some slewing ring parts used in this type of construction machinery are also widely used in some places at the beginning, such as some earth moving machinery, some excavators, even some disintegrators, some graders and a large number of road rollers used on dynamic compressors, Partial cutting machines and other machinery.
What are the causes and countermeasures for the noise caused by the slewing ring in connection with the main engine?
What is the difference between slewing rings and rotary table bearings?
What is the basic structure of the slewing ring?
This type of noise is not simply caused by the bearing, so finding the cause alone in the bearing is ineffective. The main machine should be paid attention, and the performance of the main machine should be improved if necessary. Now mainly describe the general humming and frame resonance noise in the engine.
1. The humming noise of the engine and its countermeasures. The axial vibration of the motor shaft causes a strong high frequency noise, which is a humming noise whose frequency is equal to the axial vibration frequency and can be constant or variable. The method for preventing humming is the same as the method for preventing axial vibration.
2. Bearing frame resonant noises and their countermeasures. When the axial inherent vibration of the outer ring mass system causes the axial bending inherent vibration of the bearing frame, a kind of noise is generated, which is called resonance sound. The method of increasing the preload can increase the axial natural frequency of the outer ring mass system, destroy the resonance state and reduce the noise.
1. slewing rings
slewing ring is a new type of mechanical parts consisting of inner and outer rings and rolling elements. slewing ring is a large bearing that can carry comprehensive loads and at the same time can carry large axial and radial loads and tilting moments.
2. Rotary table bearings
Rotary table bearing is a kind of large bearing with special structure, which can carry large axial loads, radial loads, tilting moments and other comprehensive loads at the same time, and integrates several functions such as support, rotation, transmission, fixation and soon.
slewing rings usually consist of screw, slewing ring, housing, motor and other components. Since the core component adopts a slewing ring, it can bear axial force, radial force and tilting torque at the same time. There are many forms, but the structure and composition are basically the same.
From left to right are (upper part):
1. Outer ring (with or without teeth) 2. Sealing tape 3. Rolling elements (ball or roller)4. Oil filler nozzle
From left and right are (lower part): 1. Plug 2. Plug pin 3. Inner ring (with or without teeth) 4. Distance block or cage 5. Mounting hole (wire hole or smooth hole).
The quality of the slewing ring also has a major influence on its performance. LYXQL Slewing Bearing Co., Ltd. as "national brand leader in China slewing ring industry" can ensure the quality of the products and after-sales service for its product. Here, the purchased user will find the right slewing ring for customers.
