Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
In the description of the present invention, unless explicitly stated and limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
In the present invention, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, as well as the first and second features not being in direct contact but being in contact with each other through additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level than the second feature.
As shown in fig. 1-7, a continuous casting roll bearing of the present application comprises: a bearing inner race 10 and a bearing outer race 11. A cage 13 is provided between the bearing outer race 11 and the bearing inner race 10. The holder 13 is formed with a plurality of receiving chambers. Rolling bodies 12 are arranged in the placing cavity. The rolling bodies 12 are uniformly arranged in the placing cavity, and gaps among the rolling bodies 12 are small. The design of the full rolling bodies 12 maximizes the load carrying capacity of the bearing. Both ends of the rolling bodies 12 abut against the cage 13. The full rolling element 12 design with cage 13 can avoid the rolling element 12 scattering during operation of the bearing, thereby making installation simpler and more convenient, and simultaneously has the capability of maximum eccentricity and axial floating, providing optimal performance. The outer peripheral surface of the rolling element 12 abuts against the outer side surface of the bearing inner ring 10 and the inner side surface of the bearing outer ring 11. The bearing inner race 10 has a cylindrical shape. The inner side surface of the bearing outer ring 11 is formed with a fitting concave surface 111 for fitting the rolling elements 12. The rolling elements 12 are arc-shaped with a special shaping. The width of the mating concave surface 111 in the axial direction of the bearing outer race 11 is larger than the width of the rolling elements 12. The outer surface of the bearing outer ring 11 is cylindrical. The unique internal geometry design allows for optimizing the contact stress distribution and stability of the rolling elements 12, thereby improving the service life of the bearing. When the bearing does not have axial floating and eccentric conditions, the stress distribution diagram is shown in fig. 4, and the bearing is in three-point uniform contact. In this state, the load distribution of three points is relatively uniform, and the bearing has relatively strong radial bearing capacity. When the bearing is in an axially floating or eccentric state, as shown in fig. 5, the force applied to the bearing rolling element 12 by the initial bearing outer ring 11 is not uniform at both ends, and the load applied to the bearing rolling element 12 increases at one end and decreases at the other end. Because the rolling element 12 always seeks an excellent state of stress balance, the end of the rolling element 12 with high load moves to the end with low load in the operation process until the new mechanical balance among the parts of the bearing is achieved, and the parts of the bearing inner ring 10, the bearing outer ring 11, the rolling element 12 and the like reach a new stable state, as shown in fig. 6. In this state, the bearing capacity of the bearing is not affected by axial floating, eccentricity, and the like of the bearing.
As a further alternative, the bearing inner race 10 and the bearing outer race 11 are arranged in parallel. The relative displacement of the bearing inner ring 10 and the bearing outer ring 11 in the horizontal direction is 0-6 mm, and the axial floating of the bearing caused by the thermal deformation of the continuous casting roll shaft can be effectively realized.
As a further solution, on the basis of being parallel to each other, a deflection angle of 0-0.5 ° can be formed between the plane in which the radius of the bearing inner ring 10 is located and the plane in which the radius of the bearing outer ring 11 is located, so that angular displacement caused by deflection of the continuous casting roll shaft can be effectively dealt with. The deflection-resistant eccentric function of the bearing can be performed simultaneously with the axial floating-resistant function, which is not provided by the conventional bearing.
Further, the outer diameter of the bearing outer race 11 is 180mm. The inner diameter of the bearing outer race 11 is 135.5mm. The inner diameter of the bearing inner race 10 has a value of 120mm. These dimensions comply with the ISO standard, and the higher static radial bearing capacity maximizes the reliability of the bearing.
As a further proposal, the bearing inner ring 10 and the bearing outer ring 11 are both made of GCr15 steel materials. The bearing has a hard and durable rolling surface and a flexible inner core, can effectively resist abrasion and fatigue damage, and prolongs the service life of the bearing.
A strength analysis method for a continuous casting roller bearing is to calculate the stress condition of the bearing, firstly, the stress analysis is carried out on the continuous casting roller, and then the stress condition of the bearing is deduced according to the stress balance condition of acting force and reacting force. In continuous casting operations, the stresses on the rolls are relatively complex, of which the static pressure and the rolling force under light pressure are the most important. According to the formulaTo calculate the static pressure of the continuous casting billet, wherein: ρ is the density of the liquid molten steel; g is gravity acceleration; h is a i For the ith continuous casting rollA vertical height value relative to the steel level; l (L) i The roll-to-roll distance of the continuous casting roll at the ith position; w is the width of the continuous casting blank; k is the comprehensive solidification coefficient of the continuous casting billet; l is the arc length of the casting blank pulled out from the crystallizer; v (V) c -the speed of withdrawal of the cast strand.
Further, in the continuous casting operation, the continuous casting rolls are subjected to a reverse force generated by the deformation of the continuous casting slab due to reduction. According to the formula p=pi× (D 2 -d 2 ) p to calculate the reaction force to which the continuous casting roll is subjected, wherein: p is the pressure D of the hydraulic system when the hydraulic system is lightly pressed, and the diameter of a piston in the hydraulic cylinder is equal to the diameter of a piston in the hydraulic cylinder; d is the diameter of the piston rod in the hydraulic cylinder.
As a further proposal, the continuous casting roller is formed by connecting three sectional rollers, and the total number of the rollers is 6. The stress formula of the continuous casting blank is as follows: f=f 1 +F 2 +F 3 +F 4 +F 5 +F 6 Wherein: f is the stress of the continuous casting blank, F 1 For the first bearing to bear force F 2 For the first bearing to bear force F 3 For the first bearing to bear force F 4 For the first bearing to bear force F 5 For the first bearing to bear force F 6 The bearing capacity of the first bearing; in the case of an even load distribution, further solutions may yield: f1 =0.1712f, f2=0.2164f, f3=0.1622f, f4=0.1618f, f5=0.1668f, f6= 0.1219F, the second bearing being subjected to the greatest load, the continuous casting roll bearing having a maximum load of f2= 0.2164 f= 66.87kN; maximum design capacity fstock=co×e of continuous casting roll bearing, where Co is static rated load value 880kN, e is maximum pressure coefficient 0.2146, fstock=880 kn× 0.2146 = 188.848kN. Maximum bearing capacity F of continuous casting roller bearing 2 Far less than the maximum design bearing capacity Fbearing of the continuous casting roller bearing, namely the bearing can not be overloaded.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be appreciated by persons skilled in the art that the above embodiments are not intended to limit the invention in any way, and that all technical solutions obtained by means of equivalent substitutions or equivalent transformations fall within the scope of the invention.
