Description
Technical field
The utility model relates to a kind of bearing-lubricating device, more particularly, relates to a kind of diaphragm pump bearing-lubricating device.
Background technique
Power end is the crucial section dress of diaphragm pump, and it transforms into the straight line motion of fluid end piston by by bent axle, connecting rod, the first-class connecting rod that forms of cross with motor, rotatablely moving of speed reducer section dress.
Tradition bent axle supported on both sides is owing to lacking necessary lubricating fitting, and the supported on both sides bearing heating heats up in the operation process of pump, causes the bearing thermal distortion to strengthen, and reduce working life, not only affected the continuous operation rate of equipment, also caused certain potential safety hazard.
Summary of the invention
The utility model is exactly for the problems referred to above, remedies the deficiencies in the prior art, and a kind of diaphragm pump bearing-lubricating device of simple in structure, high lubricating effect is provided.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technological scheme.
The utility model comprises tank at power end of diaphragm pump, and the bearing housing of bearing is fixed on the casing, and bearing is made of bearing outer ring, bearing inner race and roller, and the built-in axial region of bearing dress is in the outside of casing, be provided with bearing gland corresponding to bearing and bearing housing; Its structure outline is: oil inlet hole one end in the bearing housing links to each other with the lubrication system pipeline in the casing, and the other end is corresponding with the through hole on the bearing outer ring; Oil outlet one end of bearing housing inner bottom part links to each other with box house, and the other end is corresponding with the leakage of oil groove that arranges between bearing and the lower bearing gland.
As a kind of preferred version of the present utility model, described oil outlet is two, and symmetrical with respect to center line.Further, the angle between two oil outlets and the center line is 30 °.By said structure, can guarantee that the bearing gland inner chamber can store certain lubricant oil, the roller of bearing bottom is in the bath lubrication.
Bearing when mounted, through hole on the bearing is corresponding with oil inlet hole on the bearing housing to bother very much in order to make, and therefore as another kind of preferred version of the present utility model, can at bearing outer ring one annular groove be set corresponding to the outlet of oil inlet hole, in this annular groove through hole is set.
Compared with prior art the beneficial effects of the utility model are: the utility model adopts profile shaft bearing sleeve structure with holes, can realize good lubrication to the supported on both sides bearing by injecting lubricant oil, reduced membrane-pump power-end equipment in operation process, the frictional heating and the bearing thermal distortion that cause because of insufficient lubrication, prolong the working life of bearing, improved the stability of equipment operation.
Description of drawings
Fig. 1 is use phase diagram of the present utility model.

Wherein, 1 be casing, 2 for the lubrication system pipeline, 3 for bearing housing, 4 for oil inlet hole, 5 for bearing, 6 for axial region dress, 7 for oil outlet, 8 for the leakage of oil groove, 9 for bearing inner race, 10 for bearing gland, 11 for roller, 12 for bearing outer ring, 13 be line centered by the through hole, 14.
Embodiment
The utility model comprises tank at power end of diaphragm pump 1, the bearing housing 3 of bearing 5 is fixed on the casing 1, bearing 5 is made of bearing outer ring 12, bearing inner race 9 and roller 11, the built-in axial regions dress of bearing 5 6(connecting rods), in the outside of casing 1, be provided with bearing gland 10 corresponding to bearing 5 and bearing housing 3; Lubrication system pipeline 2 in oil inlet hole 4 one ends of bearing housing 3 interior upper ends and the casing 1 links to each other, and the other end is corresponding with the through hole 13 on the bearing outer ring 12; Oil outlet 7 one ends of bearing housing 3 inner bottom parts and 1 inner linking to each other of casing, the other end is corresponding with the leakage of oil groove 8 that arranges between bearing 5 and the lower bearing gland 11.
Described oil outlet 7 is two, and with respect to center line 14 symmetries.Further, the angle between two oil outlets 7 and the center line 14 is 30 °.
Outlet corresponding to oil inlet hole 4 arranges an annular groove at bearing outer ring 12, and through hole 13 is set in this annular groove.
During work, lubricant oil, is flowed between bearing inner race 9 and the bearing outer ring 12 through the oil inlet hole 4 at bearing housing 3 tops, the through hole 13 of bearing outer ring 12 by the lubrication system pipeline 2 on the casing 1, and roller 11 is lubricated.Between the bearing gland 10 of bottom and the bearing outer ring 12 leakage of oil groove 8 is arranged, because the angle between two oil outlets 7 and the center line 14 is 30 °, the entrance of leakage of oil groove 8 and two oil outlets 7 is corresponding, therefore working as lubricant oil enters in the bearing gland 11 from roller 10 right sides, and chamber storage within it a certain amount of after, arrive the entry position of oil outlet 7, flow in the casing 1 through oil outlet 7, and the lubricant oil that overflows from roller 11 left sides directly carries out in the casing 1; The lubricant oil that is back in the casing 1 is collected Reusability by lubrication system pipeline 2.
