As the central axis of the excavator, the slewing bearing is generally not subject to serious failures, such as breakage of the slewing bearing, but even such a small probability of occurrence may occur from time to time during the work of the excavator! In the final analysis, on the one hand, the machine friends neglected the observation and detection of the slewing bearing, and did not pay attention to it when the fault was minor.
What does the light series slewing bearing include?
How to maintain the crane slewing bearing?
What are the application areas of slewing bearings?
The light slewing bearing has the same structural form as the ordinary slewing bearing, with light weight and flexible rotation. Widely used in food machinery, filling machinery, environmental protection machinery and other fields.
1. HS series
Single row four-point contact ball slewing bearing
The single-row four-point contact ball slewing bearing is composed of two races, with a compact structure, and the steel ball contacts the arc raceway at four points. Mainly used in truck cranes, tower cranes, excavators, pile drivers, engineering vehicles, radar scanning equipment and other machines that are subjected to overturning moment, vertical axial force, and horizontal inclination force.
2. HJ series
Single row cross roller slewing bearing
The single-row cross-roller slewing bearing consists of two races, with compact structure, high manufacturing accuracy, small assembly clearance, and high requirements for installation accuracy. Overturning moment and large radial force are widely used in transportation, construction machinery and military products.
When carrying out maintenance work, first of all, pay attention to the danger of being dragged into the rotary pinion, crushing and shearing. When performing the following tasks, make sure that no maintenance personnel are in the main boom, the danger zone between the boarding car and the reel, or between the disembarking and reel, when the engine is started to perform the necessary slewing and luffing operations. Hazardous areas, except for the crane operator (in the cab).
slewing bearings are widely used, and construction machinery is the first and most widely used place for slewing bearings, such as earth-moving machinery, excavators, disintegrators, stackers and reclaimers, graders, road rollers, dynamic compactors, rock drilling machinery, roadheaders, etc. Others are:
1. Concrete machinery: concrete pump truck, concrete mixing and placing boom integrated machine, belt placing machine
2. Feeding machinery: disc feeder, sand mixer;
3. Lifting machinery: wheeled cranes, crawler cranes, portal cranes, tower cranes, fork cranes, accompanying cranes, gantry cranes;
4. Ground treatment machinery: impact reverse circulation drilling rig, rotary drilling rig, impact rotary drilling rig, rotary drilling rig, reverse circulation rotary drilling rig, positive circulation rotary drilling rig, long helical engineering drilling rig, diving engineering drilling rig, static pile driver, pile driver;
5. Engineering ships: dredgers.
