Abstract
The utility model discloses a hydrodynamic radial sliding bearing, comprising a bearing body, wherein a circumference oil supply tank is arranged along the outer circumference of the bearing body; two oil supply holes are formed in the circumference oil supply tank; two oil supply tanks are formed in the inner wall of the bearing body; each oil supply tank corresponds to one oil supply hole; the oil supply tanks are communicated with the oil supply holes; two throttling oil grooves are arranged along the axial direction of the inner wall of the bearing body, and formed in the low-pressure side of the bearing body; each throttling oil groove is correspondingly communicated with the oil supply tanks. The hydrodynamic radial sliding bearing has the advantages that the surface of each oil supply tank is an oval arc surface, and in arc transition, so that stress concentration is unlikely to occur, and the oil supply tanks are relatively shallow. Therefore, the hydrodynamic radial sliding bearing is high in strength and large in carrying capacity, and can easily form a liquid hydrodynamic oil film. The two oil supply tanks are designed, so that the shaft of the hydrodynamic radial sliding bearing can positively rotate and also can reversely rotate.
Description
Technical field
The utility model relates to a kind of sliding bearing, particularly relates to a kind of hydrodynamical journal bearing.
Background technique
At present, middle/high speed heavy-load hydrodynamical journal bearing, adopts in-line circular arc oil supply, and the axial oil supply of hydrodynamical journal bearing is circular arc or band round end rectangle groove, and this oil supply form easily causes that stress is concentrated, and should not form dynamic pressure oil film.The oil supply degree of depth is larger, and bearing intensity is low, and bearing capacity is little.
Model utility content
The purpose of this utility model is the radial sliding bearing that provides a kind of bearing capacity greatly and be easy to form dynamic pressure oil film.
The purpose of this utility model is implemented by following technological scheme, a kind of hydrodynamical journal bearing, it comprises bearing body, along the excircle of described bearing body, be provided with circumferential oil supply, in described circumferential oil supply, be provided with two oil supply holes, the inwall of described bearing body is provided with two oil supplys, the corresponding described oil supply hole of each described oil supply, described oil supply is communicated with described oil supply hole, and circumferentially oil supply provides pressure lubrication oil by oil supply hole for oil supply.Described bearing body inwall be axially arranged with two throttling oil grooves, two described throttling oil grooves are arranged at the low voltage side of described bearing body, each described throttling oil groove is corresponding to be respectively communicated with described oil supply.Owing to having designed two oil supplys, therefore axle of the present utility model can forward also can reverse.
The surface of described oil supply is oval cambered surface.The serve as reasons oil groove of the certain width that the oval cambered surface of table forms of oil supply, and for being transitioned into gradually the internal surface of sliding bearing, oil supply is relatively shallow, bearing intensity is higher; Arc is excessively difficult for forming stress to be concentrated, and is easy to form Hydrodynamic oil film.
Two described oil supplys are 60～180 ° along the angle of described bearing body center line radially, applicable to middle/high speed heavy-load hydrodynamical journal bearing.
The utility model has the advantage of, the surface of oil supply is oval cambered surface, and arc is excessive, is difficult for forming stress and concentrates; The oil supply degree of depth is relatively shallow, and therefore, the intensity of hydrodynamical journal bearing is higher, and bearing capacity is large, and is easy to form Hydrodynamic oil film; Owing to having designed two oil supplys, therefore axle of the present utility model can forward also can reverse.
Accompanying drawing explanation
Fig. 1 is a kind of axial section of hydrodynamical journal bearing.
Fig. 2 is the A-A sectional view of Fig. 1.
Bearing body 1, circumferentially oil supply 2, oil supply hole 3, throttling oil groove 4, oil supply 5.
Embodiment: a kind of hydrodynamical journal bearing, it comprises bearing body 1, along the excircle of bearing body 1, be provided with circumferential oil supply 2, circumferentially in oil supply 2, be provided with two oil supply holes 3, the inwall of bearing body 1 is provided with two oil supplys 5, the corresponding oil supply hole 3 of each oil supply 5, oil supply 5 is communicated with oil supply hole 3, and circumferential oil supply 2 provides pressure lubrication oil by oil supply hole 3 for oil supply 5.The low voltage side that is axially arranged with 4, two throttling oil grooves 4 of two throttling oil grooves and is arranged at bearing body 1 of bearing body 1 inwall, each throttling oil groove 4 is corresponding to be respectively communicated with oil supply 5.Owing to having designed two oil supplys 5, therefore axle of the present utility model can forward also can reverse.The surface of oil supply 5 is oval cambered surface.The serve as reasons oil groove of the certain width that the oval cambered surface of table forms of oil supply 5, and for being transitioned into gradually the internal surface of sliding bearing, oil supply 5 is relatively shallow, bearing intensity is higher; Arc is excessively difficult for forming stress to be concentrated, and is easy to form Hydrodynamic oil film.Two oil supplys 5 are 60～180 ° along the angle of bearing body 1 center line radially, applicable to middle/high speed heavy-load hydrodynamical journal bearing.
Claims (3)
