The invention relates to a machine unit consisting of a motor and one of the motor-driven pump, which is mounted on a common, essentially rectangular base plate, which is intended for permanent installation on a foundation, are permanently arranged.

Floor panels are usually made of iron or steel. For the sake of it's weight and the However, a satisfactory rigidity cannot be achieved at cost. It is therefore with such Floor plates required, the changes in shape that occur when fastening to a foundation to compensate by careful and cumbersome adjustment work. The alignment of the shafts of the machine assembly each other is a complicated and costly process. When applying the base plate on a foundation, the originally correct alignment of the machines is achieved through warping the base plate is lost and in many cases cannot be restored even after reworking restored to the desired level of accuracy.

It is also a machine base plate has become known, which consists of a poured with concrete There is a weak iron structure that can be transported by pouring it with the concrete before shipping is made. In this composite construction, the concrete achieves a high degree of rigidity, while any tensile stresses occurring to a considerable extent from the box-shaped sheet metal body be included. However, the manufacturing cost and weight of such a composite structure are still relatively high.

The invention has the task of providing a machine unit of the type specified at the beginning create, in which the floor slab consists essentially of concrete and without a supporting iron cladding so that it is lighter in weight and manufactured at a lower cost can be known as constructions.

The object set is achieved according to the invention in a machine assembly of the initially introduced specified type in that the plate over most of its surface from exposed Concrete executed and provided on the underside with three supports, the middle parts for attachment of fasteners are formed on the foundation and two of which are supports in the corners of one narrow side of the plate, which is assigned to the pump side of the system, laid are, while the third support is in the middle of the machine assembly with a common base plate

opposite narrow side and carries the motor side of the plate.

In the machine assembly according to the invention, the base plate is on the pump side with two and Provided with a support on the motor side. This has the advantage that with the three-point mounting known per se at the same time the part of the unit where the greater forces occur, namely the pump part, is better supported.

In the drawing, an embodiment of the invention is shown.

Fi g. 1 and 3 show diagrammatically a concrete slab, seen obliquely from above or below;

Fig.2 is a central longitudinal section along the line IMI of Fig. 1, and

F i g. 4 is a cross section along the line IV-IV of FIG. 1.

The base plate 10 made of concrete is essentially closed or solid, ie it has none of the lower recesses which are characteristic of a U-profile made of iron or steel. Reinforcing bars 12 are inserted into the concrete in a known manner. The base plate is intended for a pump unit, the pump part of which is set up on three plates 14, 16, 18 which are each cast on a projection 20, 22 and 24, respectively. For the installation of the drive motor, two plates 26 are cast into place at the opposite end of the base plate.

The bottom plate 10 is provided on the utner side with three rounded supports 28, 30 and 32, from which the two supports 28 and 30 to the for the

Claims (1)

Pump certain side of the floor slab are laid while the support 32 is on the opposite side is provided. In the middle of the supports, openings 34 extend from the bottom to the countersunk top Surface of the plate. Bolts are firmly connected to the foundation in these openings or screws introduced onto which nuts are screwed. The nuts then sit in the recessed parts of the concrete slab, which next to the supports 28, 30 between the projections 20, 22,24 xo are formed or is designated by 36 next to the support 32. The two plates 26 made of steel or the like cast into the concrete at the end of the motor have on the underside washers 38 made of a material that is significantly softer or a lower density than the concrete has. They can also be designed so that their melting point can easily be reached. the Disks 38 extend over the greater part of the surface of the plates 26 and thereby provide the Possibility of drilling new holes in the panels 26 to accommodate different dimensions of the machines without damaging the drills and thread cutting heads. Claim: Machine unit, consisting of a motor and a pump driven by the motor, which on a common, essentially rectangular base plate, which is for permanent installation is determined on a foundation, are firmly arranged, characterized in, that the plate (10) is made of exposed concrete over most of its surface and on the underside with three supports (28, 30, 32) is provided, the middle parts of which for the Attaching fasteners are formed on the foundation and two of which Supports (28, 30) in the corners of one narrow side of the plate, which is the pump side of the system is assigned, are relocated, while the third support (32) is in the middle of the opposite On the narrow side and carries the motor side of the plate.
