Abstract
The utility model provides an oil leakage prevention device for a shaft seal of an electric motor, and includes the electric motor and a gearbox, a gear on a rotation shaft of the motor is engaged and connected with the gearbox, and the shaft seal is arranged between the rotation shaft of the electric motor and the gearbox, the device is characterized in that an oil-throwing oil ring is arranged on the rotation shaft of the electric motor. The utility model has the advantages of simple, reasonable structure and convenient mounting.
Description
Technical field:
The utility model relates to a kind of envelope anti-oil leakage device, relates in particular in a kind of gear box that adopts splash lubrication the device of the anti-leakage of oil of motor shaft envelope.
Technical background:
Under the general installation form of reducing motor in when work, because the machine shaft high speed rotating produces centrifugal force, casing stores a certain amount of gear oil simultaneously, make casing have bigger pressure, internal pressure is greater than the casing ambient pressure, gear oil can be directly along axial external leakage, and usually takes place to cause motor to burn out accident because of motor shaft leak sealing oil.
Summary of the invention:
The utility model has mainly solved the problem of motor shaft leak sealing oil, and a kind of simple and practical motor shaft envelope anti-oil leakage device is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of motor shaft envelope anti-oil leakage device, comprise motor and gear box, gear on the machine shaft is connected with gear box from the form of engagement, be provided with the axle envelope between described machine shaft and the gear box, be characterized in that machine shaft is provided with oil and throws disc.
As a kind of preferred version of such scheme, described oil is thrown disc and is UFO-like, and it is that the inclination angle is 10 °～45 ° inclined-plane that this oil is thrown the disc edge.
As a kind of preferred version of such scheme, described oil is thrown between disc and the gear box and is provided with the space, and gapping interval is 2mm～3mm.
The utility model has the advantages that simple and reasonable, easy for installation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of installation form structural representation of reductor;
Fig. 2 is a kind of structural representation that oil is thrown disc.
Embodiment:
As shown in Figure 1, mainly comprise motor and gear box, gear on the machine shaft is connected on the gear box, is meshed with inner gear of the gear box, is provided with oil and throws disc 1 on described machine shaft, described oil is thrown disc and is adopted the magnitude of interference that its armful is clamped on the machine shaft, as shown in Figure 2, this oil is thrown disc and is UFO-like, and its edge is that the inclination angle is 10 °～45 ° inclined-plane 2, be provided with the space when oil is thrown the disc installation and between gearbox wall, gapping interval is 2mm～3mm.
When the machine shaft high speed rotating, oil is thrown disc 1 with the machine shaft high speed rotating, utilizes action of centrifugal force that lubricating oil is radially got rid of to the bearing housing inwall, flows back to gear box along inwall, has stoped gear oil to enter the problem of motor shaft envelope.In addition, after employing oil is thrown disc 1, seal channel has also been strengthened, made the gear oil of leakage become tortuous flowing, increased flow resistance greatly by original streamlined flow.Therefore by very little by throwing the gear oil that lets out behind the disc, the last knife-type oil stripping action that passes through the outside framework oil seal of back again will all leak gear oil and cut the oil return pond.
Claims (3)
1. a motor shaft seals anti-oil leakage device, comprise motor and gear box, gear on the machine shaft is connected with gear box from the form of engagement, is provided with the axle envelope between described machine shaft and the gear box, and it is characterized in that: machine shaft is provided with oil and throws disc (1).
2. motor shaft envelope anti-oil leakage device according to claim 1 is characterized in that described oil throwing disc (1) is UFO-like, and it is that the inclination angle is 10 °～45 ° inclined-plane (2) that this oil is thrown disc edge.
