Abstract
The utility model discloses a slewing bearing of a tooth-shaped chamfering. The slewing bearing comprises an oil nozzle, a plug, a taper pin, an outer ring, a steel ball, an isolation block, a sealing strip and an inner ring, wherein the outer ring is provided with an oil hole, a plugging hole and a pin hole; the outer periphery of the inner ring is provided with an outer annular arc groove, the inner periphery of the outer ring is provided with an inner annular arc groove, and the inner annular arc groove and the outer annular arc groove are mutually matched to form a raceway for enabling a ball to operate; the steel ball arranged in the plugging hole and the isolation block are connected with the inner ring and outer ring, the plug is inserted into the plugging hole, the taper pin is inserted into the pin hole to fix the plug, the oil hole is formed on the outer periphery of the outer ring, and the oil nozzle is inserted into the oil hole. The slewing bearing provided by the utility model has the advantages that the phenomena of tooth surface scratches and snaggleteeth caused by borne radial applied force of the slewing bearing are reduced, meanwhile, the vibration and noises generated in the rotating engagement transmission process of the slewing bearing and a small gear matched with the slewing bearing are further reduced, the service life of the slewing bearing is prolonged, and the operation reliability and stability are improved.
Description
Technical field
The utility model relates to the structure-design technique field of pivoting support, relates in particular to a kind of pivoting support of profile of tooth chamfering.
Background technique
Pivoting support is used widely in real industry, by people, be called " joint of machine ", between two articles, to need to do relative rotation motion, need again to bear the necessary important transmission part of machinery of axial force, radial force, tilting moment simultaneously, have compact structure, motion steadily, the feature such as the high and bearing capacity of precision is strong.Except various engineering machinery, the application area of pivoting support expands at present gradually, as the equipment such as harbour facilities, metallurgical equipment, drill platform have started to use pivoting support to replace original bearing on a large scale.
In actual use, can there are some defects in traditional pivoting support, for example excavator, in the process of excavation or fragmentation, can cause the inner ring of pivoting support to occur the phenomenons such as broken teeth, flank of tooth cut.The theoretical analysis is known, and the power that produces these defects is mainly derived from excavator in the course of the work in the face of the reaction force of excavator, and this reaction force produces one along pivoting support relative displacement radially by promoting small gear in the course of the work.Again because the backlash between the small gear on inner ring and the excavator of pivoting support is less, when relative displacement value is greater than backlash, small gear and inner ring gear position produce extrusion-deformation, thereby cause inner ring gear position because of the excessive appearance of shearing force, to do sth. in advance the phenomenons such as broken teeth or flank of tooth cut, and make the two in rotation engagement driving process, produce certain vibration, noise, serious impact the working life of pivoting support with the mechanical part matching, reduced stability and the reliability of associated machines operation.
Model utility content
The utility model object be exactly on inner ring in order to reduce traditional pivoting support and mechanical part with matching small gear in machinery working procedure because of the stressed technological deficiency occurring, and the pivoting support of a kind of profile of tooth chamfering of design.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of pivoting support of profile of tooth chamfering, comprise oil nozzle, stop up, taper pin, outer ring, steel ball, spacing block, Stamping Steel Ribbon and inner ring, it is characterized in that: described outer ring is provided with oilhole, plugging hole and pin-and-hole, the outer circumferential face of inner ring offers outer ring arc groove, the inner peripheral surface of outer ring offers interior annular arc groove, interior annular arc groove and outer ring arc groove cooperatively interact and form the raceway for ball operation, by plugging hole, pack steel ball into and be connected inner ring and outer ring with spacing block, stop up and insert in plugging hole, taper pin inserts fixing obstruction in pin-and-hole, oilhole is located on the outer circumferential face of outer ring, oil nozzle inserts oilhole inside.
The pivoting support of described a kind of profile of tooth chamfering, is characterized in that: Stamping Steel Ribbon is equipped with respectively in described raceway above and below.
The pivoting support of described a kind of profile of tooth chamfering, is characterized in that: the material of described inner ring and outer ring is 42CrMo.
The pivoting support of described a kind of profile of tooth chamfering, is characterized in that: on described inner ring, have positioning through hole.
The utility model inner ring adopts different profile of tooth chamferings according to the difference of modulus: during modulus m < 10, tooth top position all fall 45 ° of chamferings; Modulus m >=10 o'clock, tooth top major part position is 45 ° of chamferings.
The advantage of model utility: the chamfering that is certain number of degrees by the mending teeth of gear of the utility model pivoting support inner ring, to increase the relative gap value between small gear on the mechanical part with matching of inner ring gear position, reduction produces the phenomenons such as flank of tooth cut, broken teeth because pivoting support bears radial effect power, also further reduced vibration, noise that pivoting support and small gear with matching produce in rotation engagement driving process, improved working life and reliability of operation and the stability of pivoting support simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.A kind of pivoting support of profile of tooth chamfering, comprise oil nozzle 8, stop up 6, taper pin 7, outer ring 1, steel ball 2, spacing block 3, Stamping Steel Ribbon 4 and inner ring 5, described outer ring 1 is provided with oilhole, plugging hole and pin-and-hole, the outer circumferential face of inner ring 5 offers outer ring arc groove, the inner peripheral surface of outer ring 1 offers interior annular arc groove, interior annular arc groove and outer ring arc groove cooperatively interact and form the raceway for ball operation, by plugging hole, pack steel ball 2 into and be connected inner ring 5 and outer ring 1 with spacing block 3, stopping up 6 inserts in plugging hole, taper pin 7 inserts fixing obstruction 6 in pin-and-hole, oilhole is located on 1 outer circumferential face of outer ring, oil nozzle 8 inserts oilhole inside.
Stamping Steel Ribbon 4 is equipped with respectively in raceway above and below.The material of inner ring 5 and outer ring 1 is 42CrMo.On inner ring 5, have positioning through hole.
