Abstract
A sliding bearing comprises an upper bearing bush and a lower bearing bush which are connected in an involutory manner; the upper bearing bush and the lower bearing bush are provided with oil holes which are radially communicated; an axial oil groove is arranged on the wall of the shaft hole of the bearing and at the position of the orifice of the oil hole; and axial micro grooves are arranged on the wall of the shaft hole at the periphery of the oil groove. The utility model discloses well oilhole has ensured with the combination of axial oil groove that the shaft hole wall has sufficient lubricating oil, and the setting up of miniature oil groove makes lubricating oil form liquid dynamic pressure oil film more easily, has promoted the bearing capacity of oil film to the bearing, has effectively reduced the contact between slide bearing and axle surface, avoids the lubrication inefficacy.
Description
Technical field
The utility model relates to a kind of sliding bearing, belongs to mechanical transmissioning piece technical field.
Background technique
Bearing is a kind of important component in contemporary machinery, comprises rolling bearing and two kinds, sliding bearing, and a main supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures the effect of its passback precision.
Sliding bearing is the bearing worked under sliding friction, during use, generally needs to adopt lubricant oil to lubricate.Under liquid lubrication condition, sliding bearing directly contacts with the undeveloped life of lubricated oil content of the surface of axle, can greatly reduce the wearing and tearing on driving component surface; In addition, oil film also has certain vibration absorption ability.But in actual use, the acute variation of load is easy to the bearing capacity destroying oil film, and wear and tear in the face making axle corresponding with bearing, make bearing premature failure, working life is shorter.
Chinese utility model patent (Authorization Notice No.: CN 203570835 U, authorized announcement date: on 04 30th, 2014, title: a kind of hydrodynamical journal bearing) disclose a kind of sliding bearing: this sliding bearing comprises bearing body, and its bearing body is provided with two radial oil supply holes; The madial wall of bearing body is provided with two oil supplys, and each oil supply correspondence is communicated with an oil supply hole, and the surface of described oil supply is oval cambered surface.In this technological scheme, the surface of oil supply is oval cambered surface, excessive with bearing madial wall arc; This structure not easily forms that stress is concentrated, the degree of depth is also more shallow and be easy to form Hydrodynamic oil film, and the bearing of this structure not only possesses good structural strength, and the bearing capacity of its oil film also promotes to some extent simultaneously.But in this technological scheme, oil film is strong not enough to the bearing capacity of bearing, has the space promoted further.
Summary of the invention
The purpose of this utility model is for the defect strong not to the bearing capacity of bearing of lubricating oil oil film in existing sliding bearing, provides a kind of structure simple, and oil film is stronger to the bearing capacity of bearing, the sliding bearing of longer service life.
For achieving the above object, technical solution of the present utility model is:
A kind of sliding bearing, comprises top bearing shell and the lower bearing of involutory connection; Described top bearing shell and lower bearing are provided with radial through oilhole; On the axis hole wall of bearing, the position in oilhole aperture is provided with axial oil groove; The axis hole wall of described oil groove periphery is furnished with axial micro-recesses.
Further, described micro-recesses to arrange the periphery that equidistant mode is trapped among oil groove more.
Further, described micro-recesses is rectangle groove, dovetail groove or fusiformis groove, and the area of its notch is 0.02 square millimeter ~ 0.04 square millimeter, and the degree of depth is 0.1 millimeter ~ 0.2 millimeter; Distance between adjacent two micro-recesses is 0.1 millimeter ~ 0.2 millimeter.
Compared with prior art, the beneficial effects of the utility model are:
The aperture place that the utility model is positioned on axis hole wall at the through oilhole of radial direction is provided with axial oil groove, and on the axis hole wall of this oil groove periphery, arrange the miniature oil groove that a circle is axial, and micro-recesses to arrange the periphery that equidistant mode is trapped among oil groove more; In this structure, the combination of oilhole and axial oil groove ensure that axis hole wall has sufficient lubricant oil to lubricate, the setting of miniature oil groove then makes lubricant oil more easily form Hydrodynamic oil film, improve the bearing capacity of oil film to bearing, effectively reduce the contact between sliding bearing and axle surface, avoid lubrication failure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged view of the utility model part A;
Fig. 3 is the plan view of the utility model lower bearing;
In figure, top bearing shell 1, lower bearing 2, journal stirrup 3, bolt hole 4, oilhole 5, oil groove 6, micro-recesses 7.
Embodiment
Illustrate below in conjunction with accompanying drawing and with specific embodiment mode, the utility model to be described in further detail.
See Fig. 1 to Fig. 3, a kind of sliding bearing, comprise top bearing shell 1 and the lower bearing 2 of involutory connection, top bearing shell 1 is corresponding with lower bearing 2 is provided with journal stirrup 3, on corresponding journal stirrup 3, correspondence has bolt hole 4, and top bearing shell 1 and lower bearing 2 are by being fixed together through the bolt of bolt hole 4; Described top bearing shell 1 and lower bearing 2 are provided with radial through oilhole 5; On the axis hole wall of bearing, the position in oilhole 5 aperture is provided with axial oil groove 6, and the axis of oil groove 6 parallels with the axis of bearing, and the axial length of oil groove 6 is less than the axial dimension of brearing bore wall; The axis hole wall of described oil groove 6 periphery is furnished with axial micro-recesses 7, and the axis of micro-recesses 7 parallels with the axis of bearing.
Preferably, described micro-recesses 7 to arrange the periphery that equidistant mode is trapped among oil groove 6 more.
Preferably, described micro-recesses 7 can be rectangle groove, dovetail groove or fusiformis groove (not shown), and the area of its notch is 0.02 square millimeter ~ 0.04 square millimeter, and groove depth is 0.1 millimeter ~ 0.2 millimeter; Distance between adjacent two micro-recesses 7 is 0.1 millimeter ~ 0.2 millimeter.
Above content is the further description done the utility model in conjunction with embodiment; can not think that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; the simple replacement made, all should be considered as belonging to protection domain of the present utility model.
