The turntable slewing bearing is a large bearing with special structure that can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time, and integrates various functions such as support, rotation, transmission and fixation. Its function is to connect the upper and lower parts of the machine together, and at the same time
How to clean up the contamination of slewing bearing? It is difficult to avoid the intrusion of dust and impurities in the work of mechanical equipment. As a rolling bearing used in large and medium-sized or heavy machinery and equipment, the slewing bearing itself contains mounting holes, grease holes and sealing equipment.
How did the steel balls of Slewing Ring Bearing fit in? Slewing Ring Bearing is a commonly used part in machinery. It consists of inner ring, outer ring, rolling structure, etc. The rolling is distributed between the inner ring and the outer ring. With the operation of the bearing, the ball structure is firmly stuck between the inner ring and the outer ring. . So, do you know how the steel balls of Slewing Ring Bearing got in? Bearing assembly is also called a set. The following small preparation introduces the production of steel balls and the process of matching the set.
Burrs usually appear on the surface of metal or non-metal machined parts, but also on bearings. For example, rotary supports may cause burrs to certain parts during production and affect bearing assembly, inspection, performance and service life. In particular, when burrs appear on seals or bearings, the bearing may not work properly, causing heat generation, oil leakage, or oil leakage. So, how to remove the burr on the rotating support point? Let's find out with Yantai Zhiyuan factory.
Depending on the material, assembly, tolerance fit, lubrication and other factors of the Slewing Ring Bearing, the life of the Slewing Ring Bearing under normal conditions varies between 10,000-192,000 hours. What we usually call the service life of a bearing depends on the bearing type. Generally speaking, the service life of bearings (such as general bearings) refers to situations that cannot work normally, such as pitting, peeling, etc.
The short tooth of the slewing bearing is one of the reasons for the failure of the bearing, which may cause different degrees of problems. If the short tooth appears during use, the bearing running accuracy is serious, which may affect the normal operation of the equipment. So why does the slewing bearing break the tooth? Below we analyze the reasons for broken teeth of slewing bearings from three aspects of production, installation and use, and propose corresponding solutions.
Crossed cylindrical roller bearings and crossed roller slewing bearings (crossed cylindrical roller slewing rings) are very similar in structure and function. Such as high precision, stable torque, long life and so on. On the CNC machine tool turntable and indexing table, on the CNC vertical grinder, machine tool direct drive motor and other mechanical equipment, the shoulder, waist, wrist, elbow, knuckle and other parts of industrial robots are abandoned
Slewing Ring Bearing is widely used, and construction machinery is the first and most widely used place for Slewing Ring Bearing, such as earth-moving machinery, excavators, disintegrators, stackers and reclaimers, graders, road rollers, dynamic compactors, rock drilling machinery, roadheaders Wait. Others are:
However, when using the slewing bearing to install, sometimes there is a sharp sound, but I don't know what caused it, and I don't know how to solve it. Yantai Zhiyuan Machinery Co., Ltd. comprehensively introduced the five reasons for the abnormal sound of the slewing bearing.
Slewing Ring Bearing is a large bearing with special structure that can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time, and integrates various functions such as support, rotation, transmission and fixation. When installing Slewing Ring Bearing, we should also pay attention to its installation characteristics, now we will introduce it.
Slewing Ring Bearing is a large bearing with special structure that can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time, and integrates various functions such as support, rotation, transmission and fixation.
The slewing ring and the slewing bearing have the same origin and the same origin, and the slewing ring was gradually developed into a slewing bearing. The structure is based on four-point ball bearings, and the mounting holes of the inner and outer rings are distributed. It is unprecedentedly applied in installation, debugging, use and maintenance.
