Fig. 2 illustrates the end view that is used for according to the heel piece of fixture of the present invention;

Fig. 3 illustrates the section of heel piece shown in Figure 2; And

Fig. 4 illustrates the vertical view of heel piece shown in Figure 2.

Embodiment

Fig. 1 be illustrated on the stator case 12 according to fixture 10 of the present invention.Stator case 10 has the matrix 36 of cylindrical shell shape, is formed with fin on the outer surface of this matrix.Fin 36 extends on the outer surface in the axial direction and is arranged in 4 groups in the mode of orientation parallel to each other.The free end of every group of fin 36 roughly is on the plane.Every group (fin) defined by two boundary fin 38.The boundary fin 38 of two adjacent groups is perpendicular to one another basically.

On these boundary fin 38, a lower margin installing zone 40 is set.Lower margin installing zone 40 comprises housing construction section 20.Housing construction section 20 comprises corresponding surface 22 and another corresponding surface 26 and the threaded bores 28 that is designed to blind hole.Corresponding surface 22 and another corresponding surface 26 are perpendicular to one another.The axis of threaded bores 28 is with by 26 planes that become of corresponding surface 22 and another corresponding surface at angle, and this angle is preferably 45 degree.Preferably, two housing construction sections 20 are being set successively on the axial direction of stator case 12 in lower margin installing zone 40.

On stator case, be provided with and amount to four lower margin installing zones 40.

On lower margin installing zone 40 by bolt one heel piece 14 as fixture 15.Fixture 15 passes the hole 23 in the heel piece 14 and screws in the threaded bores 28 for this reason.Also it is contemplated that the fixture 15 of clamping apparatus, rivet or other removable pines or non-disconnectable pine.

Heel piece 14 has a construction section 16.Construction section 16 comprises two bearing-surfaces parallel to each other 18.Construction section 16 also has another bearing-surface 24.Under installment state, one in two bearing-surfaces 18 abuts on the corresponding surface 22, and this another bearing-surface 24 abuts on another corresponding surface 26.By ground layout installed surface 18 makes it with another installed surface 24 and corresponding surface 22 and another corresponding surface 26 actings in conjunction according to the present invention, heel piece can be fixed on the stator case 12, thereby in two bearing-surfaces 18 one be abutted on another corresponding surface 26 and another bearing-surface 24 abuts on the corresponding surface 22.Therefore, can in any two different positions, heel piece 14 be installed on all four lower margin installing zones 40 of stator case 12.Like this, only utilize a kind of heel piece 14 of execution mode just can stator case 12 be installed with multiple different installation site.Simple storage and reliable the installation have been realized like this to heel piece 14.

In order to simplify the fixing of the removable loose formula of heel piece 14 on stator (housing) 12, construction section 16 has two holes 23.These two holes 23 are perpendicular to one another and inner intersecting of heel piece 14 of solid formation in other cases.The axis in hole 23 and single bearing-surface 18 and the 3rd bearing-surface 24 form the angle of 45 degree.The end regions that deviates from stator case 12 under installment state in hole 23 has bigger diameter, thereby is formed for admitting the section of immersing oneself in 30 of the bolt head 32 of bolt.As shown in Figure 3, respectively the section of immersing oneself in 30 stopped before itself and hole 23 are with right angle intersection.

Heel piece 14 have a cross section be leg-of-mutton, substantially for prismatic matrix.As shown in Figure 4, on the end, in the extension of the outer surface of matrix, form a fixed head.Fixed head has hole or slotted hole.Heel piece 14 can be fixed on the corresponding device thereof by these slotted holes and hole.

To bearing-surface 18 and the 3rd bearing-surface 24 and corresponding surface 22 and another corresponding surface 26, reprocess to reach definite surface roughness and flatness in the mode of cutting down material.

Stator case 12 and heel piece 14 preferably manufacture foundry goods, particularly spheroidal graphite casting pig or spheroidal graphite cast-iron.
