According to one Embodiment of the invention can be provided that at least two variants, one of which is a smaller engine size compared to the another variant, at least a part of the rolled steel elements the engine mount a matching Cross-section, wherein in the variant with the engine smaller Size the width the used rolled steel elements whose cross section with the cross section matches at least one rolled steel element of the other variant, greater than the width is chosen is that for the engine used would be required. By using a for the mechanical stability and load resistance to big Cross-section of the motor of smaller size is an oversizing implemented in this variant, the initially increased production costs because increased Material consumption and thus at first glance disadvantageous. However, the invention is here as at the remaining advantageous Embodiments the surprising Use of knowledge that a lower extra in manufacturing costs due to increased Material consumption far greater savings in the total production cost, because not one Variety of different cross-sections held by semi-finished products must become. It is thus possible a series with a variety of variants, each on the individual requirements can be matched with to produce reasonable effort.

Alternatively or additionally, it may be provided that, in at least two variants, one of which has a smaller size gearbox compared to the other variant, at least a portion of the rolled steel elements of the gearbox have a matching cross-section, wherein in the variant with the smaller gear size, the width the rolled steel elements used, the cross section of which matches the cross section of at least one rolled steel element of the other variant, is chosen larger than the width that would be required for the gear used. The invention is here as well as the rest of The realization of the realization that the subdivision of the gear or the engine support in several layers of unprocessed, cut to length semi-finished a large variability in the mounting height, ie the height of the shaft of the motor or the transmission over a ground plane on the support structure achieved can be.

According to one Embodiment of the invention can be provided that at each Variant the upper position of the motor support by longitudinally aligned to the support structure Rolled steel elements is formed. The longitudinal direction of the support structure is through the imaginary line connecting engine and transmission given. The advantage here is that the engine during maintenance after loosening the drive connection with the transmission along the support structure shifted can be. The upper layer forms a sliding surface for the feet of the engine. Thus, the connection of the engine to the gearbox is called the clutch accomplished can be, for a maintenance accessible.

A stable mounting of the motor on the support structure, for example achieved, if in each variant, the lower position of the engine support formed by transverse to the support structure aligned rolled steel elements is.

Especially Cheap It is there, if in each variant, the rolled steel elements of lower layer of the engine mount have a thickness greater than the strenght or equal to the strength the rolled steel elements of the upper layer is.

The invention will now be explained in more detail with reference to figures:
It shows

1 a 3D view of a variant of the series according to the invention,

2 a 3D view of the support structure with conditions of the variant according to 1 .

3 a view of the variant according to 1 from above and

4 a view of the variant according to 1 from the beginning.

1 shows a 3D view of a whole with 1 designated variant of a drive package of a series of drive packages, viewed obliquely from one side.

The drive package 1 has a motor 2 , a gearbox 3 and a carrying structure 4 ,

Because of the perspective view of some components of the drive package 1 in 1 are concealed, is at the same time on the 2 to 4 to which the following description also refers.

On the support structure 4 are a motor pad 5 and a gear pad 6 educated.

On the engine pad 5 is the engine 2 mounted while on the gearbox support 6 The gear 3 is mounted.

The engine support 5 has a lower layer 7 and an upper layer 8th of rolled steel elements 9 . 10 . 11 . 12 on, which are arranged one above the other. The rolled steel elements 9 and 10 form the lower layer 7 , the rolled steel elements 11 and 12 define the upper layer 8th ,

The gearbox support 6 has a lower layer 13 and an upper layer 14 of rolled steel elements 15 . 16 . 17 . 18 on. The upper layer 14 is above the bottom layer 13 arranged. The lower layer 13 is from the in 2 apparent rolled steel elements 15 and 16 formed while the upper layer 14 from the rolled steel elements 17 and 18 is formed.

The carrying structure 4 has a profile tube 19 on.

The drive package 1 is part of a series of similarly designed drive packages, which differ from each other in size of the motors 2 and gear 3 and the load-resistant fixation of the motors 2 and gear 3 on the support structure 4 necessary dimensioning of the carrying structure 4 and the superstructures on this support structure 4 differ. The 1 to 4 show thus a prototypical example of the variants of the series.

The variants are unique by the size of the engine 2 and the size of the gearbox 3 characterized. Based on the specification of the sizes, the variant is thus clearly identifiable.

Since the variants have the same structure, each variant has rolled steel elements 9 . 10 . 11 . 12 . 15 . 16 . 17 . 18 and a profile tube 19 on. These components are manufactured as unprocessed, cut to length semi-finished products. In particular, thus are the heights of the waves of the engine 2 and the transmission 3 over the Tra gestruktur 4 on the dimensions of the rolled steel elements 9 . 10 . 11 . 12 . 15 . 16 . 17 . 18 and the profile tube 19 due to the rolling of the semi-finished products and not changed by subsequent grinding or milling.

Within the range of drive packages 1 are the cross sections used at least some rolled steel elements 9 . 10 . 11 . 12 . 15 . 16 . 17 . 18 and the profile tubes 19 chosen in accordance with at least two variants, as will be described in more detail below.

Initially, each variant has the rolled steel elements 9 . 10 . 11 . 12 . 15 . 16 . 17 . 18 within their respective location 7 . 8th . 13 . 14 the engine support 5 and the gearbox support 6 an identical cross section.

Thus, the layers are 7 and 8th the engine support 5 arranged parallel to each other. The same applies to the layers 13 and 14 the gearbox support 6 ,

Then, in each variant, the rolled steel elements 9 . 10 . 11 . 12 . 15 . 16 . 17 . 18 within their respective location 7 . 8th . 13 . 14 the engine support 5 and the gearbox support 6 a uniform length.

In a first variant, the engine points 2 a smaller size than a second variant. The gears 3 on the other hand have the same size.

In a third variant, the gearbox 3 a larger size than the first variant. The motors 2 the first variant and the third variant, however, have a uniform size.

In a fourth variant finally have the engine 2 and the gearbox 3 each a larger size than the corresponding units of the first variant.

Part of the rolled steel elements 9 . 10 . 11 . 12 the engine support 5 the variants has a matching cross-section.

To achieve this, are in the first variant and the third variant, so in the variants with the engine 2 smaller size, the width of the used rolled steel elements 9 . 10 . 11 . 12 whose cross-section coincides with the cross-section of rolled steel elements 9 . 10 . 11 . 12 the second or fourth variant, so the variants with the engine 2 larger size, matches larger than the width chosen for the motor used 2 would be structurally required. In the variants with engine 2 smaller size is thus the motor support 5 oversized.

In the first variant and the second variant has the transmission 3 compared to the third and the fourth variant on a smaller size. Nevertheless, some of the rolled steel elements exhibit 15 . 16 . 17 . 18 the gearbox support 6 the variants on a matching cross section. This is achieved in that in the first and the second variant, the width of the used rolled steel elements 15 . 16 . 17 . 18 whose cross-section coincides with the cross-section of rolled steel elements 15 . 16 . 17 . 18 the other variant is greater than the width chosen for the gear used 3 would be structurally required. This results in an oversizing of the gear pad 6 in the first variant and the second variant.

As in 2 It can be seen that the upper layer is in each variant 8th the engine support 5 through two longitudinally to the support structure 4 oriented, parallel to each other rolled steel elements 11 . 12 educated. The motor 2 may be prior to attachment to these rolled steel elements 11 . 12 along the support structure 4 So on the transmission 3 be moved to or from this.

The lower layer 7 the engine support 5 is through two transverse to the support structure 4 oriented, parallel to each other rolled steel elements 9 . 10 educated.

In the first and second variants, the rolled steel elements 9 . 10 the lower layer 7 the engine support 5 a thickness greater than the thickness of the rolled steel elements 11 . 12 the upper layer 8th the engine support 5 is. The presentation of the 1 to 4 is not to scale.

In the third and fourth variants, the rolled steel elements 9 . 10 the lower layer 7 the engine support 5 a thickness equal to the strength of the rolled steel elements 11 . 12 the upper layer 8th the engine support 5 is.

As can be seen from the figures, the variants are the rolled steel elements 17 . 18 the upper layer 14 the gearbox support 6 parallel to the rolled steel elements 15 . 16 the lower layer 13 the gearbox support 3 aligned.

The rolled steel elements 17 . 18 the upper layer 14 the gearbox support 3 further have a thickness greater than the thickness of the rolled steel elements 15 . 16 the lower layer 13 the gearbox support 3 is.

Finally, in the variants, the rolled steel elements 17 . 18 the upper layer 14 the gearbox support 3 a length that is significantly larger as the length of the rolled steel elements 15 . 16 the lower layer 13 the gearbox support 3 is. The length of the rolled steel elements 17 . 18 is at least 1.5 times the length of the rolled steel elements 15 . 16 to leave enough space for the fasteners 41 for a detachable connection. The fasteners 41 , realized in the example as a screw-nut combination, penetrate thus only the upper rolled steel elements 17 . 18 ,

In the variants, the rolled steel elements 17 . 18 the upper layer 14 the gearbox support 3 a width that is significantly smaller than the width of the rolled steel elements 15 . 16 the lower layer 13 the gearbox support 3 is. The width of the rolled steel elements 15 . 16 the lower layer 13 is more than double, even in variants more than 2.5 times or three times the width of the upper rolled steel elements 17 . 18 the upper layer 14 the gearbox support 6 ,

The rolled steel elements 9 . 10 . 11 . 12 . 15 . 16 . 17 . 18 are with the profile tube 19 and connected to each other by line-shaped welded joints. The rolled steel elements 17 . 18 the upper layer 14 the gearbox support 6 are with the rolled steel elements 15 . 16 the lower layer 13 the gearbox support 6 by a lengthwise direction of the rolled steel elements 15 . 16 . 17 . 18 , ie transversely to the extension direction of the support structure 4 , led fillet weld joined.

In one variant, the rolled steel elements 17 . 18 the upper layer 14 the gearbox support 3 a cross section which is equal to the cross section of the rolled steel elements 15 . 16 the lower layer 13 the gearbox support 3 another variant.

The first and the second variant, characterized by the size of the engine 2 and / or the size of the transmission 3 distinguish, have a profile tube 19 with matching cross section and matching length on.

The profile tubes 19 are manufactured as square hollow sections with square cross-section.

In the variants, the rolled steel elements 15 . 16 the lower layer 13 the gearbox support 6 a uniform cross-section. The cross sections of corresponding rolled steel elements 15 . 16 to different variants are so congruent.

In the first variant and the second variants, so in the variants with the same size of the transmission 3 , assign the rolled steel elements 17 . 18 the upper layer 14 the gearbox support 6 a uniform cross-section. The same applies to the third and the fourth variant.

The first variant is for the rolled steel elements 11 . 12 the upper layer 8th the engine support 5 used a cross section identical to the cross section of the rolled steel elements 15 . 16 the lower layer 14 the gearbox support 6 this variant is.

In addition, this cross-section becomes for the rolled steel elements 15 . 16 the lower layer 14 the gearbox support 6 the second variant, so a variant with an engine 2 larger size, used.

In the first variant and the third variant, so in variants with the same size of the engine 2 , assign the rolled steel elements 11 . 12 the upper layer 8th the engine support 5 a uniform width.

The same applies to the second variant and the fourth variant. These rolled steel elements 11 . 12 even have a uniform cross section and differ only in length.

In the variants with the same size of the gearbox 3 , So the first variant and the second variant or the third variant and the fourth variant, is the profile tube 19 at the ends in each case by a head plate 20 completed, which is designed identically for the variants. The headstock 20 is even identical in all variants.

In the figures, the carrying structure 4 with the profile tube 19 shown as a foundation frame. In other variants, the support structure 4 designed as a motor swing, by on the profile tube 19 an eyelet is formed, which engages a torque arm.

The drive package 1 also has a first clutch 21 between engine 2 and gear 3 and a second clutch 22 on an output shaft 23 of the transmission 3 on.

The first clutch 21 is through a first hood 24 and a first tub 25 covered. Likewise, the second clutch 22 through a second hood 26 and a second tub 27 covered.

Yes, according to the size of the motor 2 and the transmission 3 and depending on the requirements of the drive package 1 are in the variants differently designed couplings 21 . 22 intended.

The variants thus each sub-variants are summarized, which by the first clutch 21 and the second clutch 22 at the same size of the motor 2 and the transmission 3 are clearly identified.

In a first and a second such sub-variant are the first hood 24 and the second hood 26 formed identically within a sub-variant, although the clutches 21 . 22 are formed differently.

It is further envisaged that the hood 24 the first sub-variant is identical to the hood 24 a third sub-variant, which has a motor deviating size or a gear deviating size.

Likewise, the hood 26 the second sub-variant identical to a hood 26 a fourth sub-variant.

The hood 24 between engine 2 and gear 3 The first sub-variant is also identical to a hood 26 So on the output shaft 23 , a fifth sub-variant.

The same applies to the associated tubs 25 . 27 ,

The hoods 24 . 26 are each composed of two half-hoods, as can be seen from the figures.

The use of standardized hood dimensions results in the problem that, depending on the sub-variant and / or requirements on the output side, the overlapping of the rotating parts and in particular couplings 21 . 22 and waves is not complete, but that gape gaps that create an accident risk.

Therefore, with the sub-variants on the first hood 24 and / or on the second hood 26 on at least one axially oriented side 28 . 29 . 30 . 31 a collar 32 appropriate. Axial is to be understood here in relation to the respective covered shaft.

For example, in the sub-variant according to 3 and 4 on the axially oriented side of such a collar 32 attached to the exposed part of the output shaft 23 to cover. Through the collar 32 is the by the axial dimension of the second hood 26 remaining axial area with rotating parts on the second clutch 22 covered.

For mounting the first hood 24 has the support structure for each variant 4 a hood pad 33 on. On this is the first hood 24 with the associated first tub 25 on the hood pad 33 assembled.

The hood pad 33 is with untreated, cut to length rolled steel elements 34 . 35 educated.

These rolled steel elements 34 . 35 the hood pad 33 have an identical cross-section in the sub-variants and are identical.

In the execution of the support structure 4 as a foundation frame has the support structure 4 angular feet 36 for mounting the drive package 1 on a pad.

The angle feet 36 have two thighs 37 . 38 , where the angle feet 36 with a thigh 37 on the profile tube 19 are attached. The other thigh 38 is for fixing the drive package 1 provided on a base.

In two different variants, their transmission 3 a uniform size, are identical angular feet 36 with identical thighs 37 . 38 intended. To achieve different heights of the output shaft 23 of the transmission 3 above the pad are the angle feet 36 with the thighs 37 in the two different variants in different heights on the profile tube 19 attached. Since the attachment is made by welding, any heights can be adjusted.

For cooling the gearbox 3 is between the clutch 21 and the transmission 3 on its driving wave a fan 43 arranged, which is moved by the driving shaft.

At the transmission 3 is also an auxiliary engine 39 arranged.

The variants of the series are manufactured using the following process for the production of drive packages 1 a series of drive packages 1 manufactured.

First, for the production of the engine support 5 and the gearbox support 6 Rolled steels held with a fixed, limited grid of cross sections.

The Number of cross sections in the grid is smaller than that Number of variants of the series.

In a first step, the production of the engine support 5 and the gearbox support 6 for the desired size of the motor 2 and size of the gearbox 3 selected from a classification table rolled steels with specific cross sections.

This mapping table gives the same Cross section of at least one rolled steel for different sizes of the motor 2 and the transmission 3 according to the structural design of the variants, as has been explained above with reference to the description of the variants.

In a second step, rolled steel elements are made from the selected rolled steels 9 . 10 . 11 . 12 . 15 . 16 . 17 . 18 made by cutting to length.

In a third step, the finished rolled steel elements will be made 9 . 10 . 11 . 12 . 15 . 16 . 17 . 18 for the formation of the engine support 5 or gearbox support 6 with each other and with the support structure 19 connected by welding.

Finally, in a fourth step, the engine 2 and the gearbox 3 on the engine support 5 and the gearbox support 6 assembled.

The cross sections are determined in the assignment table so that the reuse of a cross section is prioritized prior to the choice of the smallest constructively possible cross section. This principle is particularly independent of the length of the respective rolled steel element 9 . 10 . 11 . 12 . 15 . 16 . 17 . 18 implemented.

To connect the engine 2 with the gearbox 3 is for a desired variant, by a desired size of a motor 2 and a desired size of a transmission 3 describes a sub-variant determined by a first clutch 21 for the connection of the engine 2 with the gearbox 3 and a second clutch 22 for the output shaft 23 of the transmission 3 to get voted.

These couplings 21 . 22 , in particular, by hoods 24 . 26 covered as described above.

For this purpose, at the first clutch 21 and the second clutch 22 Hood 24 . 26 and tubs 25 . 27 with a fixed, limited grid of dimensions, the number of dimensions in the grid being smaller than the number of sub-variants of the series.

It will now be an electronically stored assignment table for the hoods 24 . 26 and tubs 25 . 27 used, based on the for the first clutch 21 and the second clutch 22 a first hood 24 and a second hood 26 and a first tub 25 and a second tub 27 to be selected.

Depending on the gaping gaps between the hoods 24 . 26 and to these axially adjacent housing parts is on at least one axially oriented side 28 . 29 . 30 . 31 a hood 24 . 26 a collar 32 arranged. This collar 32 is formed by a bent, welded sheet metal strip.

The width of the collar 32 is chosen such that a by the axial dimension of the selected first hood 24 or second hood 26 remaining uncovered, axial area with rotating parts in the first clutch 24 or second clutch 26 is covered. It is therefore no larger hood and no larger tub needed, but the reproached measure can be used again.

The allocation table reflects the reuse of the hoods 24 . 26 and tubs 25 . 27 again.

After this assignment table for the hoods 24 . 26 and tubs 25 . 27 become the same hoods 24 . 26 and the same tubs 25 . 27 at various sub-variants selected to a configuration of the drive packages 1 reached, which was described in the various sub-variants.

For example, the first hood selected in a sub-variant is 24 and the associated first tub 25 identical to the second hood selected for the same and a third sub-variant 26 and associated second tub 27 ,

The hoods 24 . 26 are in the allocation table for the hoods 24 . 26 and tubs 25 . 27 so set that reusing a hood 24 . 26 , in particular at the location of the first clutch 21 and / or second clutch 22 Priority is given to choosing the smallest structurally possible dimension of the hood 24 . 26 and / or pan 25 . 27 ,

The hoods 24 . 26 and tubs 25 . 27 are in each sub-variant by hood covers 33 on the support structure 4 attached.

The hood pads 33 are - similar to the engine pads 5 and gearboxes 6 - Made of rolled steels, which are held in a limited grid of cross-sections, the number of cross-sections is smaller than the number of sub-variants of the series.

The next step will be based on an electronically stored and available allocation table for the hood cover 33 for the desired sub-variant, the cross-sections of the rolled steels for the hood support 33 selected.

In a next step is the hood pad 33 formed by selecting from the selected rolled steels by cutting to length rolled steel elements 34 . 35 manufactured and with the support structure 4 connected become.

Alternatively, the finished cut rolled steel elements 34 . 35 held in a grid of lengths, wherein the number of different lengths of the grid is smaller than the number of sub-variants of the series, and it will be based on the allocation table, the lengths for the rolled steel elements 34 . 35 determined and selected.

In a next step will be to assemble the cover of the first clutch 21 the first hood 24 and / or first tub 25 at the hood pad 33 assembled. Subsequently, the second hood 26 with the second tub 27 on other rolled steel elements 42 attached. The rolled steel elements 42 are also on the profile tube 19 welded.

The Creation of electronically stored allocation tables completes as described below.

The starting point is the determination for each variant of that coupling 21 with the largest possible dimensions. For these results in a maximum thickness, ie thickness, the lower and upper layers 7 . 8th respectively. 13 . 14 ,

Now be for the gearbox 6 the strengths, ie the extent in the vertical direction of the layers 13 and 14 established. This is the lower layer 13 determined so that a uniform cross-section for all variants can be used for these.

Subsequently, the strengths of the layers 7 . 8th the engine pads 5 chosen so that, on the one hand, as often as possible, the cross section of the rolled steel elements 15 . 16 the lower layer 13 the gearbox support 5 is used and that as few new cross-sections must be introduced. Finally the upper layers become 14 the engine pads 5 determined so that as few new cross-sections must be introduced. This requirement may be a further, recursive revision of the cross-sectional allocation in the upper layer 14 the gearbox support 6 make necessary. A person skilled in the art will thus arrive in a few recursion steps in an allocation table which reproduces the features of the series according to the invention.

An analogous procedure leads to a mapping table for the hoods 24 . 26 and tubs 25 . 27 ,

The reusability of the cross sections can be further improved if the engine support 5 and the gearbox support 6 in more than two layers 9 . 10 . 13 . 14 be divided.

In the series of drive packages 1 are the engine pad 5 an engine 2 and the gearbox support 6 a gearbox 3 each of at least two horizontally oriented layers 7 . 8th . 13 . 14 unprocessed, cut to length rolled steel elements 9 . 10 . 11 . 13 . 15 . 16 . 17 . 18 formed to reduce the required component stock of the series in different variants of the series the same cross-section for rolled steel elements 9 . 10 . 11 . 13 . 15 . 16 . 17 . 18 is used in corresponding and different position.
