Abstract

The invention discloses a metal shaft sleeve type ceramic impeller with a wing plate, and belongs to the technical field of ceramic impeller manufacture. One end of a metal internal thread shaft sleeve (1) is provided with a regular polygonal metal wing plate (2) integrally processed with the shaft sleeve, and the metal internal thread shaft sleeve (1) is in firm and reliable matched connection with a ceramic impeller main body (3) together through the regular polygonal metal wing plate (2); and the regular polygonal metal wing plate (2) is horizontally arranged in a matched corresponding groove (6) on the surface of the ceramic impeller main body (3) with a rear vane (4) through a sticking and mechanical locking mechanism, and the outer lateral surface of the regular polygonal metal wing plate (2) is provided with an auxiliary vane (7) integrally processed with the wing plate and matched corresponding to the rear vane (4). The strength of torsion moment resistance at a shaft seat can be greatly improved, and the ceramic impeller is not discarded due to cracking at the shaft seat no matter disassembly or assembly.

Description

A kind of metal shaft shell type pottery impeller with wing plate

Technical field

The invention belongs to ceramic impeller manufacture technology field, relate to a kind of metal shaft shell type pottery impeller with wing plate.

Background technique

In the existing technology, the cylinder type metal internal thread axle sleeve direct-burried of the ceramic impeller in the ceramicpump is in the stupalith of ceramic impeller bodies, and its advantage is simple in structure, the easy making; Also can satisfy the requirement when running well; Its deficiency is that cylinder type metal internal thread axle sleeve links together with the structure and the ceramic impeller bodies of straight reason in stupalith, and the surface of contact of its outer surface and stupalith is less; Adhesive strength is limited; Therefore especially direct-burried is very limited at the thickness of the stupalith of metal internal thread axle sleeve evagination on the so-called metal internal thread axle sleeve head outside the ceramic impeller bodies plane, and its circumferential connection part with ceramic impeller bodies plane is that the axle bed place is the weakness of torsibility square, when the ceramic impeller of installation or removal; Because the restriction of operating space; Have only through the ceramic impeller bodies of direct powerful twisting and could realize, under the effect of powerful torsional moment, occur in the weakness of above-mentioned described torsional moment often---" axle bed place " rhegma, thus cause ceramic impeller integral body to be scrapped; Promptly uneconomical, also can influence continuous ordinary production sometimes.

Summary of the invention

The technical problem that solves:

A kind of metal shaft shell type pottery impeller with wing plate is provided; Can overcome the deficiency that exists in the existing technology; Adopt the metal internal thread axle sleeve of band wing plate, and link together, can improve the intensity of ceramic impeller axle bed place torsibility square greatly with the structure and the ceramic impeller bodies of non-direct-burried in stupalith; In the time of guaranteeing installation or removal pottery impeller, it can not scrapped because of axle bed place rhegma.

The technological scheme that adopts:

A kind of metal shaft shell type pottery impeller with wing plate; Comprise ceramic impeller bodies, the metal internal thread axle sleeve of being with intra vane; It is characterized in that: the metal alar plate that has the regular polygon that processes with its integral body on the end of metal internal thread axle sleeve; The metal internal thread axle sleeve links together with structure and the ceramic impeller bodies solid and reliable supporting formula of non-direct-burried in stupalith through the metal alar plate of regular polygon, and have on the metal alar plate of regular polygon process with its integral body and with ceramic impeller bodies plane on the supporting corresponding auxiliary blade of back blade.

Beneficial effect:

Because the metal alar plate and the metal internal thread axle sleeve integral body of regular polygon process; And link together with the structure and the solid and reliable supporting formula of ceramic impeller bodies of non-direct-burried in stupalith through the metal alar plate of regular polygon; The torsional moment that produces in the time of making installation or removal pottery impeller is delivered on the metal alar plate of regular polygon through the metal internal thread axle sleeve; Thereby can improve the intensity of the torsibility square at axle bed place greatly, dismantle or install ceramic impeller and can not scrap because of axle bed place rhegma.

Embodiment

In conjunction with further explanation in detail of accompanying drawing;

As shown in Figure 1; The metal alar plate 2 that has the regular polygon that processes with its integral body on one end of metal internal thread axle sleeve 1; Metal internal thread axle sleeve 1 links together with structure and the ceramic impeller bodies 3 solid and reliable supporting formulas of non-direct-burried in stupalith through the metal alar plate 2 of regular polygon, and have on the metal alar plate 2 of regular polygon process with its integral body and with ceramic impeller bodies 3 lip-deep back blade 4 supporting corresponding auxiliary blades 7.

Like Fig. 1, shown in 2; The metal alar plate 2 of metal internal thread axle sleeve 1 through regular polygon with the structure that ceramic impeller bodies 3 solid and reliable supporting formulas link together is: have the metal alar plate 2 supporting corresponding groove 6 that have on the surface 5 of back blade 4 with regular polygon in ceramic impeller bodies 3; The thickness of the degree of depth of groove 6 and the metal alar plate of regular polygon 2 is adaptive; Back blade 4 on the surface 5 that after the metal alar plate 2 that must guarantee regular polygon can be packed in the groove 6 and linked together with ceramic impeller bodies 3 solid and reliable supporting formulas, said ceramic impeller bodies 3 had that the surface 5 of back blade 4 is concordant with the outer surface of the metal alar plate 2 of regular polygon, the auxiliary blade 7 on metal alar plate 2 outer surfaces and said ceramic impeller bodies 3 have back blade 4 complements one another corresponding; The metal alar plate 2 and the ceramic impeller bodies 3 solid and reliable supporting formulas of regular polygon link together; The metal alar plate 2 that is regular polygon is with in the bonded structure groove 6 of packing into for sleeping in; Be to have adhesive layer 8 between internal surface and periphery and the bottom surface of groove 6 and the periphery of metal alar plate 2 of regular polygon; Also has simultaneously axial mechanical interlocking mechanism between the metal alar plate 2 of regular polygon and the ceramic impeller bodies 3; Concrete structure does; The attachment hole 9 that on the metal alar plate 2 of regular polygon, has regular distribution has on ceramic impeller bodies 3 and attachment hole 9 supporting corresponding axial entire body open-works 10, and metal locking element 11 passes the attachment hole 9 and the 10 back lockings of entire body open-work of supporting correspondence; Metal locking element 11 is through being spirally connected, riveting or weld, or any two kinds of methods combine to lock.

As shown in Figure 1, the metal alar plate 2 of said regular polygon is a regular pentagon.
