Specific embodiment
The specific embodiment of the built-up shaft pressure cap for providing the present invention below in conjunction with the accompanying drawings elaborates.
Referring to Fig. 1 and Fig. 2, a kind of built-up shaft pressure cap of the invention includes bearing gland matrix 100 and seal 200.
The bearing gland matrix 100 has a centre bore 108, and the seal 200 is arranged in the centre bore 108, and with institute
State bearing gland matrix to be fitted together to, the seal 200 is set in pump shaft（Do not indicated in accompanying drawing）On, prevent oil leakage.Institute
State bearing gland matrix 100 and manufactured by cast iron or cast steel and process, the seal 200 is made of clear material, for example, have
Machine glass etc..The bearing gland matrix 100 and the seal 200 are formed in one.
The outer surface of the seal 200 is provided with connecting hole 207（It is shown in Fig. 6）, screw 400 is by the connection
Be fixed on the seal 200 on bearing gland matrix 100 by hole 207.Further, in the seal 200 towards bearing pressure
The side of lid matrix 100 is provided with seal groove 206（It is shown in Fig. 5）, sealing ring 300 is arranged in the seal groove 206, with
The bearing gland matrix 100 and the seal 200 are sealed, lubricating oil from seal 200 and bearing gland matrix is prevented
Revealed between 100.
Further, referring to Fig. 3 and Fig. 4, closed on one end of bearing body in the medial surface of bearing gland matrix 100 and be provided with
Matrix oil-recovery tank 101, the oil of bearing gland side can flow back to bearing body accumulator by matrix oil-recovery tank 101.In the bearing
The side exterior surface of gland matrix 100 sets persevering position lubricating cup interface 102, is set in the side wall of the bearing gland matrix 100
Have along the radially extending tank filler sleeve 103 of radial direction, and the axial direction for axially extending connected with the radial direction tank filler sleeve 103 adds
Oilhole 104, the permanent position lubricating cup interface 102 is connected with the radial direction tank filler sleeve 103, so the permanent position lubricating cup interface 102 with
The radial direction tank filler sleeve 103 and axial tank filler sleeve 104 form a path, and permanent position lubricating cup interface 102 connects permanent position lubricating cup, Jin Erke
From repairing in trend bearing chamber.It is easy to make due to the simple structure of bearing gland matrix 100, and can well ensure permanent position
The relative position of lubricating cup interface 102, it is ensured that permanent position lubricating cup solves bearing body processing and miss all the time in normal automatic repairing state
The problem of the automatic repairing failure of permanent position lubricating cup that difference is caused, while alleviating casting and the difficulty of processing of bearing body.
Further, the surface that the bearing gland matrix 100 is contacted with bearing body sets seal groove 105, for placing
Sealing ring, prevents oil leak between bearing gland matrix 100 and bearing body.The sealing ring can be O-ring.In the bearing pressure
Lid matrix 100 is provided with equally distributed matrix screw counter bore 106, for example, four or six.Described matrix screw counter bore 106
For being fixed with bearing body phase.Two matrix dismounting screws 107 being arranged symmetrically are provided with the bearing gland matrix 100,
It is convenient and swift for dismantling the bearing gland matrix 100, and the bearing gland matrix 100 is not damaged.
Referring to Fig. 5 and Fig. 6, the seal 200 is made of clear material, and the lubricating oil in the bearing body is through sealing
Body 200 is visual, the outer surface of the seal 200 is provided with oil level scale groove, to play a part of oil ga(u)ge.In this specific implementation
In mode, the oil level scale groove includes oil level line 201 high, normal oil level line 202, low oil level line 203, can be by seal
Three oil level lines accurate oil level clearly observed in bearing body directly perceived on 200 just plays a part of oil ga(u)ge.Because close
The envelope simple structure of body 200, it is easy to make, and can well ensure the relative position of oil level line, it is ensured that oil level is in normal
In the range of use, the oil leak that bearing body oil ga(u)ge hole machined error is caused is solved the problems, such as, while alleviating bearing body
Casting and difficulty of processing.
Further, radial seal groove 204 is provided with the inner side of the seal 200 with shaft seal, in the seal
200 are provided with axial oil-recovery tank 205 towards one end that bearing body is closed on the side of pump shaft.For example, being set on the seal 200
There is a 2-3 radial labyrinth seal groove 204, an axial oil-recovery tank 205, axial oil-recovery tank 205 is in lower section during installation.Due to sealing
Body 200 is supported using nonmetallic materials, therefore, radial labyrinth seal groove 204 and axial oil-recovery tank 205 can be poured into directly
Type, without processing, can improve the sealing effectiveness between seal 200 and axle and interstage sleeve, and seal 200 only needs to change close after wearing and tearing
Envelope body 200, without changing bearing gland matrix 100, bearing gland matrix 100 is reusable effectively to economize on resources.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member, under the premise without departing from the principles of the invention, can also make some improvements and modifications, and these improvements and modifications also should be regarded as
Protection scope of the present invention.
