Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.
Reference picture 1-4, a kind of oilhole bearing cap for bearing oil leakproof, including lid 1 is installed, in installation lid 1
Centre position is provided with the first mounting groove, and the inner bottom part of the first mounting groove is provided with first through hole, and the first mounting groove is threaded with installation
Ring 2, the internal circumferential of mounting ring 2 is provided with cavity, and rubber seal 3 is provided with cavity, and rubber seal 3 uses the shape of concave
Formula, so, when air pressure is higher in cavity, this part is grown up faster, it is easier to tight contacted between with rotating shaft, rubber seal
Circle 3 is offseted by hold-down gear with the inwall of cavity, and hold-down gear includes two wire loops 12, two two ends difference of wire loop
The first mounting blocks and the second mounting blocks are fixedly connected with, the first mounting blocks and the second mounting blocks are bolted, are conveniently replaceable
Rubber seal 3, cavity is provided with port near the side of rubber seal 3, and the inwall of cavity is provided with the second through hole, and first installs
The inwall of groove is provided with the third through-hole corresponding with the second lead to the hole site, and the outside for installing lid 1 is provided with and third through-hole position phase
Corresponding second mounting groove, the inwall of third through-hole is fixedly connected with air permeable plate 4, and air permeable plate 4 is near the side of the second mounting groove
Ball sealer 6 is connected with by spring 5, orifice diameter of the third through-hole near the second mounting groove side is straight less than third through-hole
Footpath, the orifice diameter that the second mounting groove side is close to diameter greater than third through-hole of ball sealer 6 so that ball sealer 6 is in spring 5
The lower inwall with third through-hole of effect is in close contact, without being ejected, so as to play the effect of sealing type pressure, the second mounting groove
Rubber cup 7 is inside provided with, rubber cup 7 is fixed with the first straight-bar 8 away from the side of ball sealer 6, and the side of the second mounting groove is provided with
Installing port, the side wall of installing port is rotatably connected to the second straight-bar 9, and the second straight-bar 9 is rotated with the first straight-bar 8 and is connected, the second straight-bar 9
