Abstract
The utility model relates to a sealing sleeve structure, in particular to a sealing device for a vehicular supercharger, which comprises a sealing sleeve body arranged on a rotor shaft of the supercharger, wherein one end of the sealing sleeve body is provided with a sealing ring groove while the other end abuts onto an anti-thrust bearing, and one side of the sealing sleeve body connected with the anti-thrust bearing is provided with an annular oil thrower surface. The utility model mainly provides the sealing device for a vehicular supercharger capable of effectively sealing lubricating oil, preventing residual lubricating oil in an oil thrower groove from leaking after shutting down and having fine sealing effect, which resolves technical problems that the air compressor end leaks oil and residual lubricating oil in the oil thrower groove is leaky after shutting down in the prior art.
Description
Technical field
The utility model relates to a kind of stuffing box gland structure, especially designs a kind of seal arrangement of vehicle supercharger.
Background technique
Existing pressurized machine is because the motor practical use needs and the scope of application constantly enlarges, vehicles such as the bus of for example equipped boosting type motor, harbour container trailer, plateau purposes, idling, urgency are quickened, other variable parameter operations are chronic, in pressurized machine because the leakage of lubricant oil, make the machine oil that leaks enter air inlet tube, intercooler, motor, the long-pending oil of intercooler stops up air cavity can't proper functioning, causes booster performance to descend.At above-mentioned technical problem, Chinese patent: " pressurized machine stuffing box gland (CN2866986Y) ", a kind of pressurized machine stuffing box gland is disclosed, comprise the stuffing box gland body that is arranged on the supercharger rotor axle, front-end face at the stuffing box gland body also has closure gasket groove, the rear end of stuffing box gland is provided with the thrust bearing mounting groove, on the cross section in the neutral position of described stuffing box gland body, be provided with and get rid of oilhole A, the described oilhole A that gets rid of is along circumferentially evenly arranging, gets rid of to form between oilhole A and gets rid of oily blade at described adjacent two.It mainly acts on is effectively to reduce the lubricant oil that enters the seal ring position, has improved the sealability of pressurized machine.Because two oily blades that get rid of that get rid of oilhole formation get rid of oily blade and comprise an oil groove that gets rid of that is positioned at end face, owing to get rid of the end face that oil groove is positioned at the stuffing box gland body, after rotor shaft slows down, in groove, form precipitated oil easily, thereby cause the leakage of lubricant oil, influence the use of pressurized machine.
Summary of the invention
The utility model has mainly provided a kind of can getting rid of the interior residue lubricant oil of oil groove after avoiding shutting down and produce seepage, the seal arrangement of the vehicle supercharger of good sealing effect effectively with seal oil; Solve the leakage of oil of existing in prior technology gas compressor end, the technical problem of after shutdown, getting rid of residue oil seepage in the oil groove.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of seal arrangement of vehicle supercharger, comprise the stuffing box gland body that is arranged on the supercharger rotor axle, one end of described stuffing box gland body is provided with the seal ring annular groove, the other end of described stuffing box gland body is connected on the thrust bearing, and stuffing box gland body and the thrust bearing side of joining is provided with annular and gets rid of pasta.Utilize toroidal surface to get rid of oil, removed original oil groove that gets rid of, the seepage that oil has avoided shutting down residue lubricant oil in the pit is got rid of on the plane, better promotes seal action, has effectively avoided the leakage of oil of gas compressor end.
As preferably, described stuffing box gland body is "T"-shaped.The "T"-shaped step surface of stuffing box gland body gets rid of pasta as annulus, is socketed with Diffuser on its Cylindrical object and compresses thrust bearing, and lubricant oil is thrown away by step surface, can not produce deposition oil, and "T"-shaped stuffing box gland body structure is simple, easily manufactured.
As preferably, the anchor ring width that described annular is got rid of pasta is 3.05mm, and the length of described stuffing box gland body is 8.5mm.
As preferably, be provided with "T"-shaped thrust ring at the front end of described stuffing box gland body, between stuffing box gland body and thrust ring, form a groove, in groove, be provided with thrust bearing.By stuffing box gland body and thrust ring thrust bearing is fixed, simple in structure, easy for installation, leakage of oil is few.
Therefore; the seal arrangement of vehicle supercharger of the present utility model; have following characteristics: directly adopt the toroidal surface of stuffing box gland body to get rid of oil; can directly effectively avoid the leakage of oil of gas compressor end; better promoted seal action; also avoided simultaneously shutting down in the original structure of back and caused remaining lubricant oil, thereby made remaining oil seepage because oil groove is got rid of in setting.
Description of drawings:
Fig. 1 is the mounting structure schematic representation of the seal arrangement of vehicle supercharger of the present utility model.
Fig. 2 is the sectional view of the stuffing box gland body in Fig. 1.
Embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As illustrated in fig. 1 and 2, a kind of seal arrangement of vehicle supercharger, comprise stuffing box gland body 1, stuffing box gland body 1 is socketed on the rotor shaft 2, and stuffing box gland body 1 is "T"-shaped, entire length is 8.5mm, the toroidal surface at the step place of stuffing box gland body 1 is for getting rid of pasta 11, and the anchor ring width of toroidal surface is 3.05mm, partly is socketed with Diffuser 3 at the Cylindrical object of stuffing box gland body 1, Cylindrical object end partly at stuffing box gland body 1 is provided with seal ring annular groove 4, is provided with seal ring 5 in the seal ring annular groove 4.Stepped shape end face one side at stuffing box gland body 1 is connected with "T"-shaped thrust ring 6, and thrust ring 6 is socketed on the rotor shaft 2, in the groove that is formed by stuffing box gland body 1 and thrust ring 6 thrust bearing 7 is installed.When work, the stuffing box gland body rotates along with running up of rotor shaft 2, utilizes it to get rid of pasta 11 lubricant oil in the gap has been got rid of, thereby effectively avoided the leakage of oil of gas compressor end, has promoted seal action.
