High definition Ladle Turret Slewing Bearing - Internal gear double row different ball diameter slewing bearing 023.40.1250 – Wanda Detail:

The traditional axial load, radial load and overturning moment.
1. Working load: refers to the slewing bearing device in the work to bear the weight of the machine itself, and to improve the weight of heavy objects
And, slowly, the total weight is transferred to the slewing bearing device.
2. Temperature load: mechanical equipment in work, will produce a certain temperature, and all of these temperatures must be rotary
The bearing device absorbs and makes the slewing bearing bear all the temperature.
3. Wind load: mechanical work in the open air, it is necessary to consider the role of wind load, including wind direction, rain, thunderstorm days
Gas and so on. The above is only a part of the load on the slewing bearing device. In fact, the slewing bearing device has to bear more load to meet all the weight and load of the machine in work. In general, the turntable bearing itself is equipped with mounting hole, lubricating oil and sealing device, which can meet the different requirements of various main engines working under different working conditions.

4. Risk load: the unexpected and unexpected load, cross stress, risk stress, accidental violence, etc. borne by slewing bearing and slewing bearing.
Therefore, the selection of turntable bearings, there will be a safety factor to ensure that there is no risk.

3. Selection and calculation of slewing bearing

Taking a large tonnage truck crane as an example, this paper introduces the selection and calculation of three row roller slewing bearing.

Determination of axial force and overturning moment

The external load of slewing bearing includes the axial force acting on the slewing bearing device; the overturning moment along the boom and luffing plane; the horizontal force along the boom and luffing plane; and the horizontal force is generally far less than 10% of the axial force, so the influence of horizontal force can be ignored in the calculation of slewing bearing device. The axial force F and overturning moment M of slewing bearing are mainly considered. Since the horizontal inertial force, wind force and gear meshing force are also very small relative to the axial force, they can also be ignored; in addition, the weight of the spreader can also be ignored.

Single row four point contact spherical slewing bearing
The single row four point contact ball slewing bearing is composed of two seat rings, compact structure, light weight, four point contact between steel ball and arc raceway, which can bear axial force, radial force and overturning moment at the same time. Rotary conveyor, welding operator, small and medium cranes and excavators can be selected.

Double row spherical slewing bearing with different diameter
The double volleyball type slewing bearing has three seat rings. The steel ball and isolation block can be directly discharged into the upper and lower raceways. According to the stress condition, two rows of steel balls with different diameters are arranged. This kind of open assembly is very convenient. The bearing angles of the upper and lower arc raceways are 90 ° and can bear large axial force and overturning moment. When the radial force is greater than 0.1 times of the axial force, the raceway must be specially designed. The axial and radial dimensions of double row spherical slewing bearing with different diameters are relatively large and the structure is tight. It is especially suitable for tower crane, truck crane and other loading and unloading machinery with medium or above diameter.

Single row cross roller slewing bearing
Single row cross roller slewing bearing, composed of two seat rings, has the advantages of compact structure, light weight, high manufacturing accuracy, small assembly clearance and high requirements for installation accuracy. The roller is 1:1 cross arranged and can bear axial force, overturning moment and large radial force at the same time. It is widely used in lifting and transportation, engineering machinery and military products
13 series

Three row roller slewing bearing
Three row roller type slewing bearing has three seat rings. The upper and lower raceways and radial raceways are separated respectively, so that the load of each row of rollers can be determined accurately. It can bear all kinds of loads at the same time. It is one of the four products with the largest bearing capacity. The shaft and radial dimensions are large and the structure is firm. It is especially suitable for heavy machinery requiring larger diameter, such as bucket wheel excavator, wheel crane, marine crane, port crane, steel water transport turntable and large tonnage truck crane.

Light series slewing bearing

Light slewing bearing

The light slewing bearing has the same structure as the ordinary slewing bearing, which is light in weight and flexible in rotation. It is widely used in food machinery, filling machinery, environmental protection machinery and other fields.

HS series

Single row four point contact spherical slewing bearing

The single row four point contact ball slewing bearing is composed of two seat rings with compact structure and four point contact between steel ball and arc raceway. It is mainly used for truck cranes, tower cranes, excavators, pile drivers, engineering vehicles, radar scanning equipment and other machines that bear the action of overturning moment, vertical axial force and horizontal inclination force.
HJ series

Single row cross roller slewing bearing

The single row cross roller slewing bearing is composed of two seat rings, with compact structure, high manufacturing accuracy, small assembly clearance and high requirements for installation accuracy. The rollers are 1:1 cross arranged and can bear axial force, overturning moment and large radial force at the same time. It is widely used in transportation, engineering machinery and military products.
