Abstract
The invention discloses a guiding device of an oil ring of a sliding bearing. The device comprises a bearing bush, wherein the bearing bush is provided with a groove; and at least two U-shaped guiding sheets are arranged in the bearing bush groove. According to the invention, a structure is simple; manufacture cost of the bearing bush can be reduced; in addition, the guiding device can effectively limit the oil ring to swing axially; friction force between the oil ring and the guiding device is reduced; therefore, the rotating speed of the oil ring is increased when a rotating shaft is rotated in a high speed; and oil loading capacity of the oil ring is improved.
Description
Technical field
The present invention relates to a kind of sliding bearing oil ring guiding device.
Background technique
Sliding bearing needs enough lubricant oil to be lubricated and cools off, and is arranged in the oil ring in the bearing shell groove, when rotor rotates, drags oil ring by frictional force and rotates, and oil ring brings bearing with the lubricant oil in the grease chamber and is lubricated, and guarantees the normal operation of bearing.Owing to only rely on the guiding device of bearing shell groove as oil ring, for reduce and oil ring between frictional force, the roughness of groove side requires high, like this bearing shell manufacture cost height; Excessive for preventing oil ring axial runout; General groove is less with the oil ring gap, causes the oil ring side that the situation of axioversion or swing is often particularly arranged at motor with the groove contacts side surfaces like this, and existence contacts between oil ring and the groove; Even this moment, the surface roughness of groove was fine; Also can produce bigger side friction power, thereby make that the oil ring rotating speed is slack-off and even change, cause fuel feeding not enough and bearing performance is descended even damage.
Summary of the invention
To the above-mentioned technical problem that existing glide bearing ring guiding device exists, the present invention provides a kind of sliding bearing oil ring guiding device simple in structure.The present invention can limit oil ring axial runout effectively, reduces the area of contact between oil ring and the oil ring guiding device, thereby reduces the frictional force between oil ring and the oil ring guiding device, makes oil ring normally move.
The technological scheme that the present invention solves the problems of the technologies described above is: comprise bearing shell, bearing shell is provided with groove, is provided with two guiding pieces in the said bearing shell groove at least.
In the above-mentioned sliding bearing oil ring guiding device, described guiding piece is the U type.
In the above-mentioned sliding bearing oil ring guiding device, comprise two guiding pieces, two guiding pieces are installed in the interior position that becomes 45 ° with vertical direction of bearing shell groove.
Compared with prior art; The invention has the beneficial effects as follows: the present invention with the contact between oil ring and the recess sidewall convert to guiding piece between contact; Reduced area of contact; Thereby reduce the frictional force between oil ring and the oil ring guiding device greatly, make oil ring rotating speed when the rotating shaft high speed rotating increase, promoted the band oil ability of oil ring.The invention enables bearing shell groove machining accuracy and roughness to require to reduce, reduced the bearing shell processing cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a scheme of installation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figure 1, the present invention includes bearing shell 1 and two guiding pieces 2, bearing shell 1 is provided with 11, two guiding pieces 2 of groove and is the U type; Two guiding pieces 2 are installed in bearing shell 1 groove 11, are positioned to become 45 ° position with vertical direction.
As shown in Figure 2, during use, the oil ring 3 that hangs in the rotating shaft 5 is limited in two guiding pieces 2, with the axial runout of restriction oil ring 3.Guiding piece 2 separates oil ring 3 and groove side 6, makes that contact converts contact between oil ring 3 and the guiding piece 2 between oil ring 3 and the recess sidewall 6.During rotating shaft 5 rotations; Rotating shaft 5 external diameters and oil ring 3 interior radial line contacts produce frictional force and overcome surface friction drag drive oil ring 3 rotations between oil ring 3 and the guiding piece 2, and oil ring 3 bottoms are soaked in the part of bearing grease chamber lubricant oil 4 is taken in the rotating shaft 5 to bearing shell 1 fuel feeding through rotation.
