Machine envelope, full name mechanical seal, in industry common people's habit is known as machine envelope.It is it is a kind of be used to solve rotary shaft with
The device sealed between body, general machine envelope includes the structures such as axle sleeve, stationary ring, rotating ring, at present transmission ring and moving ring assembly
Torque transfer mode mainly by structure R, as shown in figure 4, i.e. moving ring assembly upper surface be arranged a triangular groove, transmission ring
The lower surface of protrusion is provided with triangular hill corresponding with triangular groove, although such structure structure is reliable, pressure-bearing
Ability is up to 4MPa.
Utility model content
The technical issues of the utility model solves is to provide a kind of high pressure-bearing property machine envelope of raising machine envelope pressure-bearing property.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of high pressure-bearing property machine envelope, including be arranged
Axle sleeve on pump shaft, transmission ring, moving ring assembly and the stationary ring that the axle sleeve is arranged with spring base respectively, successively contacts outside, also
Including gland, the gland passes through limited block and fillister head screw, is provided with the transmission protruded into transmission ring in the spring base
Screw further includes spring, and the spring one end is fixed in spring base, and the spring other end is resisted against on transmission ring, is also wrapped
Trundle is included, described trundle one end is protruded into gland, and the other end of trundle protrudes into stationary ring, the transmission ring and rotating ring group
Part is plug-in cooperation.
Further, the transmission ring side is provided with inserting section, moving ring assembly side adjacent with transmission ring is set
It is equipped with the groove matched with inserting section, the inserting section is provided with multiple, and the multiple inserting section is around transmission ring side annular
Arrangement, the groove have multiple, and the multiple groove is circular layout around moving ring assembly side.
The beneficial effects of the utility model are: the machine envelope of the utility model is slotting by changing into transmission ring and moving ring assembly
Formula structure is pulled out, so that the structure of machine envelope is more firm, and bearing capacity can be increased to 6MPa from original 4MPa, so that the machine
