Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As it is shown in figure 1, the invention provides a kind of axial face seal device.Specifically, axial face seal device is for main shaft 100
Axial plane seal.This axial face seal device at least includes gland 10, elastic component 20, stationary ring 30 and tightens part 40.Gland
10 include the first half glands 11 and the second half glands 12, and the first half glands 11 and the second half glands 12 are detachably connectable.The
Forming the cavity worn for main shaft 100 between half gland 11 and the second half glands 12, main shaft 100 is sheathed on the first half glands
11 and the second half between gland 12.Elastic component 20 is arranged at the internal perisporium of cavity, and elastic component 20 is arranged at the periphery of main shaft 100,
Stationary ring 30 is arranged between the internal perisporium of elastic component 20 and the periphery wall of main shaft 100.Tightening part 40 is at least one, at least one
The individual part 40 that tightens is arranged on gland 10, tightens part 40 and sets along the radial direction of elastic component 20 i.e. the radial direction of main shaft 100
Put, tighten part 40 be arranged in gland 10 and be connected to elastic component 20 periphery wall on.Tighten part 40 so that tightening part 40
Compressing elastic component 20, tighten part 40 and exert a force elastic component 20, with the transmission puted forth effort, stationary ring 30 is exerted a force by elastic component 20 again,
Exert a force to realize the sealing between stationary ring 30 and main shaft 100 to stationary ring 30 by elastic component 20.Wherein, part 40 is tightened permissible
For adjusting screw.
Owing to gland 10 includes removably connecting ground the first half gland 11 and the second half glands 12, main shaft 100 is arranged in the first half
In the cavity that gland 11 and the second half glands 12 are collectively forming, therefore laid-up or when changing without unloading lower main axis 100 one end
Counterpart.Such design so that workload reduces, the working time shortens, and cost reduces, the axial face seal dress of the present invention
Putting easy accessibility, and be axial face seal, the velocity gradient between rubbing surface is definite value, and frictional force does not haves end surface mechanical sealing
The defect that frictional force changes along with the change of velocity gradient value.It addition, do not have end surface mechanical sealing in use yet
