Abstract
The utility model discloses a rebound-type contact oil baffle. The rebound-type contact oil baffle comprises an oil baffle piece and a rotor which is arranged at the lower end of the oil baffle piece, wherein the oil baffle piece comprises an oil baffle ring body, a first groove, a second groove, a first inner baffle ring, a second inner baffle ring and a contact baffle ring, wherein the first groove and the second groove are arranged in the oil baffle ring body, the first inner baffle ring is arranged in the first groove, the second inner baffle ring is arranged in the second groove, the contact baffle ring is arranged at the inner end of the second inner baffle ring, and spring pieces are respectively arranged between the first inner baffle ring and the second inner baffle ring and between the first groove and the second groove; and when the rotor rotates at a high speed, lubricating oil has certain viscosity and adheres to the surface of the rotor to generate a layer of oil film which is adhered to gaps between oil seal teeth of the first inner baffle ring and the second baffle ring and the rotor, thus a self-sealing effect of the oil film is fulfilled, and the problem that the lubricating oil leaks from the side of the oil baffle is solved, and the spring pieces arranged between the first inner baffle ring and the second inner baffle ring and between the first groove and the second groove have flick effects so that abrasion is minimized, and a shaft is not damaged.
Description
Technical field
The utility model relates to a kind of back springing type contact oil catch.
Background technique
Tradition contact oil catch, its rotor can produce the problem that side is revealed between lubricant oil and oil catch when running up, can not guarantee its sealing, and oil catch spare and rotor directly contact can damage oil catch spare or rotor, reduced working life, affect course of working.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of long service life, back springing type contact oil catch simple in structure.
The utility model is achieved through the following technical solutions: a kind of back springing type contact oil catch, comprise oil catch spare and rotor, described rotor is arranged on oil catch spare lower end, described oil catch spare comprises the flinger ring body, and be arranged on the first groove and the second groove in the flinger ring body, and be arranged on the first inner baffle ring in the first groove, and be arranged on the second inner baffle ring in the second groove, and be arranged on the contact baffle ring of the second inner baffle ring inner end, be respectively equipped with spring sheet between described the first inner baffle ring, the second inner baffle ring and the first groove, the second groove.
As preferably, be noncontact seal between described the first inner baffle ring, the second inner baffle ring and rotor.
As preferably, be contact seal between described contact baffle ring and rotor.
As preferably, described oil catch spare diameter is slightly less than root diameter 0.01-0.03mm.
The beneficial effects of the utility model are: when rotor high-speed turns round, lubricant oil has certain viscosity, can be attached to rotor surface, producing one deck oil film adheres to mutually with the oil sealing tooth of the first inner baffle ring and the second inner baffle ring and the gap of rotor, thereby reach the self-packing effect of oil film, solved the problem that lubricant oil is revealed from the oil catch side, and the spring sheet that arranges between the first inner baffle ring, the second inner baffle ring and the first groove, the second groove can play the effect that flicks, make wearing and tearing reduce to minimum, and can not hurt axle.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of the utility model back springing type contact oil catch.
Embodiment
As shown in Figure 1, a kind of back springing type contact oil catch of the present utility model, comprise oil catch spare 6 and rotor 5, described rotor 5 is arranged on oil catch spare 6 lower ends, described oil catch spare 6 comprises flinger ring body 1, and be arranged on the first groove 9 and the second groove 7 in the flinger ring body 1, and be arranged on the first inner baffle ring 8 in the first groove 9, and be arranged on the second inner baffle ring 2 in the second groove 7, and being arranged on the contact baffle ring 3 of the second inner baffle ring 2 inner ends, described the first inner baffle ring 8, the second inner baffle ring 2 and the first groove 9,7 of the second grooves are respectively equipped with spring sheet 4; Because the first inner baffle ring 8, the second inner baffle ring 2 and 5 of rotors are noncontact seal, when rotor 5 runs up, lubricant oil has certain viscosity, can be attached to rotor 5 surfaces, producing one deck oil film adheres to mutually with the oil sealing tooth of the first inner baffle ring 8 and the second inner baffle ring 2 and the gap of rotor 5, thereby reach the self-packing effect of oil film, solved the problem that lubricant oil is revealed from the oil catch side.When rotor 5 and oil catch spare 6 bumped mill, the first inner baffle ring 8 and the second inner baffle ring 2 flicked by spring sheet 4 effects at once, made wearing and tearing reduce to minimum, and can not hurt axle.
Wherein, described the first inner baffle ring 8, the second inner baffle ring 2 and 5 of rotors are noncontact seal; 5 of described contact baffle ring 3 and rotors are contact seal; Described oil catch spare 6 diameters are slightly less than rotor 5 diameter 0.01-0.03mm.
Oil catch spare 6 adopts the alloy material of casting graphite, copper, antimony to make, and its characteristics are that pliability is good, wear-resistant, and rotor 5 is not had any injury, and unit operation is safe and reliable.
The beneficial effects of the utility model are: when rotor high-speed turns round, lubricant oil has certain viscosity, can be attached to rotor surface, producing one deck oil film adheres to mutually with the oil sealing tooth of the first inner baffle ring and the second inner baffle ring and the gap of rotor, thereby reach the self-packing effect of oil film, solved the problem that lubricant oil is revealed from the oil catch side, and the spring sheet that arranges between the first inner baffle ring, the second inner baffle ring and the first groove, the second groove can play the effect that flicks, make wearing and tearing reduce to minimum, and can not hurt axle.
The above only be embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
