Need to be the problem of the parts thereof of dismounting bearing chamber assembling after machinery stops could take out excess oil in art.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of unidirectional grease automatic releasing device, is installed on bearing chamber so that grease is more than certain pressure in bearing chamber
After can discharge automatically, including valve body, bead, spring and adjusting screw, valve body is in bolt shape, including cylinder and with circle
The hexagon-head that cylinder one end is solidified as a whole, cylinder periphery is provided with the external screw thread for being used for being arranged on valve body on bearing chamber, valve
Internal portion is axially arranged with circle hole shape discharge-channel, and the cylinder other end offers the circle hole shape discharge-channel connected with discharge-channel
Entrance, the discharge-channel outlet that hexagon-head radially offers more than one and connected with discharge-channel, adjusting screw axle is outside
It is provided with the screw thread for being provided with inside screw external screw thread, hexagon-head and connecting and being engaged with screw external screw thread with discharge-channel week
Hole, the diameter of discharge-channel entrance, bead and discharge-channel is incremented by successively, and it is logical with discharge that bead is located at discharge-channel entrance
Road is connected place, and spring is located in discharge-channel and one end is contacted with bead, and adjusting screw is located in screwed hole and the inner and bullet
Another end in contact of spring, spring is in compressive state and pushing against bead makes bead closely block discharge-channel entrance.
Further, discharge-channel outlet is two, and is symmetrically distributed in six using hexagon-head central axis as line of symmetry
On angle head.
Further, the diameter of discharge-channel outlet is less than the diameter of discharge-channel.
Compared with prior art, the utility model has the advantages that：
The utility model design science, it is simple in construction, it is easy to operate.
Excess oil, more than in the case of preset pressure, is discharged axle by the utility model pressure of grease in bearing chamber automatically
Hold room.So as to ensure that the reasonable oil quantity in bearing chamber, good lubricant environment is provided for bearing, reaches it just beneficial to bearing
Normal service life.
The utility model eliminates the assembling of artificial unloading's bearing chamber, takes the complicated processes of excess oil, reduces mechanical dimension
The amount of labour of shield.
The utility model can also be used for other need in excess oil or the machinery of similar grease fluid release.

Embodiment
The utility model is described in further detail with embodiment for explanation below in conjunction with the accompanying drawings, and mode of the present utility model includes
But it is not limited only to following examples.
Embodiment
As shown in Figure 1-Figure 3, a kind of unidirectional grease automatic releasing device, is installed on bearing chamber so that bearing indoor oil
Fat can discharge automatically after more than certain pressure, and the device includes valve body 1, bead 2, spring 3 and adjusting screw 4, the valve
Body 1 is in bolt shape, including cylinder 5 and the hexagon-head 6 that is solidified as a whole with the one end of cylinder 5, and the periphery of cylinder 5 is set
Have and be axially arranged with circle hole shape discharge-channel 7 inside the external screw thread for being arranged on valve body 1 on bearing chamber, the valve body 1, it is described
The other end of cylinder 5 offers the circle hole shape discharge-channel entrance 8 connected with discharge-channel 7, and the radial direction of hexagon-head 6 is opened up
The discharge-channel outlet 9 for having two and being connected with discharge-channel 7, discharge-channel outlet 9 using the central axis of hexagon-head 6 as
Line of symmetry is symmetrically distributed on hexagon-head 6, and the axial periphery of adjusting screw 4 is provided with screw external screw thread, the hexagon-head 6
Inside provided with the screwed hole that connects and be engaged with screw external screw thread with discharge-channel 7, discharge-channel entrance 8, bead 2, with
And the diameter of discharge-channel 7 is incremented by successively, the diameter of the discharge-channel outlet 9 is less than the diameter of discharge-channel 7, the bead
2 are connected place positioned at discharge-channel entrance 8 with discharge-channel 7, and the spring 3 is located in discharge-channel 7 and one end connects with bead 2
Touch, the adjusting screw 4 is located in screwed hole and the inner and another end in contact of spring 3, the spring 3 is in compressive state and supported
Tight bead 2 makes bead 2 closely block discharge-channel entrance 8.
In the utility model, in a free state spring 3 be in compressive state, bead 2 spring 3 pressure effect under,
It is in close contact with discharge-channel entrance 8, now the utility model is closed.The grease of the attachment nearby of bead 2 can strengthen
Sealing effectiveness.The pressure of spring 3 is determined by its rigidity and decrement.
When the inner side pressure of grease of valve body 1 provides pressure more than spring 3, grease will promote bead 2 to move, now grease
Into discharge-channel 7, discharged from discharge-channel outlet 9.When the inside pressure of valve body 1 reduces, bead 2 will come back to initial bit
Put, the utility model recovers closed mode.When inner space pressure is less than exterior space pressure, the utility model is remained
Closed mode, isolates inside and outside space, extraneous dust, steam cannot be introduced into inner space.
The utility model can change the pre compressed magnitude of spring 3 by tightening or unscrewing adjusting screw 4, reach that change is dynamic
