In the 10 the combination possibility is shown in a series of gearboxes. The kit for the series of geared motors is designed in such a way that different motors can be connected to different gearboxes directly or by means of an adapter. In the 10 shown gear must not be designed as a servo gearbox.

In the 1 a part essential to the invention is shown, which is compatible with the series of geared motors, that has corresponding interfaces. This essential part of the invention comprises servo geared motors, which can be assembled in various combinatorics. The shown here and connectable to the motors gearbox are servo gearboxes.

The following is now first on this, in the 1 part will be discussed:

The engine includes a motor housing 1 with stator. Depending on requirements, an encoder and / or a brake B-side connected. On the A side, the housing has an interface for connection to a motor end shield 12 . 13 . 14 on. The interface is formed by means of the A-side geometric shape of the motor housing and the positioning of the holes. The matching counter interface is in the engine end shield 12 . 13 . 14 executed. Thus, the motor housing 1 with all engine bearing labels 12 . 13 . 14 connectable, but in turn differ in other places. In particular, the associated bearing seats of the bearings and / or shaft sealing ring seats are differently executable and / or different rotor shafts can be accommodated. The rotor 2 . 3 . 4 , comprising in each case the rotor shaft, is to be selected differently. A B-side bearing of the rotor 2 . 3 . 4 is covered by the motor housing. The other A-side bearing is covered by the engine end shield.

The rotor 2 is designed with an A-side cylindrical shaft end. This is also in 2 clearly shown. In this case, the rotor shaft includes 22 of the rotor 2 also a center hole 21 , The engine end shield 23 includes a bearing seat for the bearing 25 and a shaft seal seat for the shaft seal 26 , the interface 24 is executed in the above-mentioned manner at the engine end shield and the motor housing, wherein the bores and screws for connecting the engine end shield and the motor housing are not shown.

The rotor 3 is according to 3 with the rotor shaft 32 executed, wherein the rotor shaft 32 by means of the warehouse 35 in the engine end shield 33 that the engine end shield 12 corresponds, is stored and by means of the shaft seal 36 is sealed against this. the interface 24 of the engine end shield 33 is again designed to match the same motor housing, as well as in 2 , The rotor shaft 32 of the rotor 3 is A-side by means of a key with a Aufsteckritzel 31 connected.

The rotor 4 is according to 4 with the rotor shaft 42 executed, wherein the rotor shaft 42 by means of the warehouse 45 in the engine end shield 33 that the engine end shield 12 corresponds, is stored and by means of the shaft seal 46 is sealed against this. the interface 24 of the engine end shield 33 is again designed to match the same motor housing, as well as in 2 , The rotor shaft 42 of the rotor 4 is A-side with a Einsteckritzel 41 connected.

The rotor 2 . 3 . 4 is in other embodiments of the invention in various electromechanical variants, in particular as a rotor with short-circuit cage for forming an asynchronous motor or as a rotor with glued magnets to form a synchronous motor, executable. But there are also other variants of engines used, such as reluctance motors, DC or other electric motors. For this purpose, the interface and the rotor must be appropriately designed.

Instead of the engine end shield 12 is also the engine end shield 14 with the rotors 3 or 4 usable, wherein the engine end shield 14 the same interface 24 to the motor housing 1 up points. By means of this engine end shield 14 is now the connection of all gearboxes 127 . 128 . 129 . 130 , which have a corresponding flange and in 10 shown are possible. Gearboxes that are like the angle gearbox 131 are executed with an integrated motor housing in the gearbox housing, are of course not connectable. Only at a omission of said engine end shield 14 it is connectable.

In further exemplary embodiments according to the invention, each engine end shield can also be designed as a square flange. Thus, there are more possible combinations with little more effort on components.

According to the embodiment 1 is the one with the engine end shield 12 formed motor with a planetary gear with or without planetary gear precursor 10 or with a bevel gear 7 connectable. The planetary gear is a planetary gear 8th with cylindrical output shaft end or planetary gear 9 designed with flange block drive.

According to the embodiment 1 is the one with the engine end shield 13 Engine formed over the out of the adapter flange 11 and the adapter part 6 formed adapter with a planetary gear with or without Planetengetriebevorstufe 10 or over the adapter flange 11 and the adapter part 5 formed adapter with the angle gear 7 connectable. The planetary gear is a planetary gear 8th with cylindrical output shaft end or planetary gear 9 designed with flange block drive.

The asynchronous motor 121 is executable as standard motor according to IEC standard. However, other manufacturers own designs are usable. A manufacturer's own embodiment is also in 1 shown. Here is the motor housing 1 suitable for various engines, which are characterized by engine end shield 12 . 13 . 14 and rotors 2 . 3 . 4 differ. In particular, there is also a rotor 4 with a pinion and a rotor 3 providable with Aufsteckritzel. This is an extremely compact direct attachment of one of the gearboxes 7 . 8th . 9 . 10 executable and thus adapter and the like can be saved. Since Einsteckritzel and Aufsteckritzel are provided within the modular construction of the series of the invention, a wide range of gear ratios is already achievable in the input side arranged spur gear, wherein said sprocket eintreibendes gearing part of this spur gear is.

The synchronous motor 122 is designed with square flange and is thus connectable to corresponding components having a matching interface. In particular, the adapter 126 or the gearbox 125 motor side with such an interface executable. When directly connected to the transmission is also the transmission 127 . 128 . 129 or 130 executable with such a flange. In the 10 are the gears 127 . 128 . 129 and 130 , the adapter 126 and the gearbox 125 but designed with a round flange. The above-mentioned round flanges are not just the asynchronous motor 121 , but also the asynchronous motor designed as a servomotor 123 or the inverter motor 124 connectable.

The gearbox 125 Includes a two- or three-stage spur gear and is advantageously used for very high gear reduction applications.

The adapter 126 is on the output side with the gearbox 127 . 128 . 129 or 130 connectable. Thus, the oil space of the transmission remains 127 . 128 . 129 or 130 when exchanging the adapter 126 drive side arranged engine 121 . 122 . 123 . 124 Advantageously closed.

In other embodiments, the primary gear 125 and the adapter 126 also provided with a drive-side square flange.

The flat gearbox 128 and the spur gear 127 each comprise two or three spur gears. The bevel gear 129 comprises a spur gear stage arranged on the input side and a bevel gear stage arranged on the output side. The worm gear 130 comprises a spur gear stage arranged on the input side and a worm gear stage arranged on the output side. The Spiroplangetriebe 131 includes a Spiroplangetriebestufe, ie an angular gear stage.

An essential advantage of the present modular system is that a drive-side transverse force-free transmission, for example, the planetary gear 8th . 9 . 10 , with an engine is just as connectable as a drive side non-transverse force free transmission, for example, a transmission with a drive side arranged spur gear as the transmission 7 , The transmission-side interface of the engine or the engine plus adapter is therefore equal for lateral force-free transmission and non-lateral force-free transmission.

Another significant advantage is that the inertia is selectable and thus to the customer application, so the driven load is customizable. So if a high inertia is desired and even a low torsional rigidity, a geared motor with adapter is selected, for example, the components 1 . 2 . 13 . 11 . 6 . 8th or the components 1 . 2 . 13 . 11 . 5 . 7 out 1 , A low torsional stiffness also means a so-called, softer 'drive; So torque shocks are absorbed by the geared motor to some extent. If, on the other hand, a low mass inertia and a high torsional rigidity are necessary, a geared motor without an adapter, ie with a motor directly connected to the gearbox, is selected, for example the components 1 . 3 . 12 . 7 or the components 1 . 3 . 12 . 8th or the components 1 . 4 . 12 . 9 out 1 ,

The gears, especially the gears 7 . 8th . 9 . 10 , are low-play, namely with a game of less than 3 Angular minutes per gear stage.

The motor-side interface of the adapter flange 11 is designed with very little tolerance, so with high precision. Thus, the engine with its engine end shield 13 very precisely degradable. In particular, said interface with less tolerance, that is more accurate, executed as the interface of the adapter to the transmission out.

In the 5 this is the adapter part 5 and the adapter flange 11 comprehensive adapter shown in section. In 6 this is the adapter part 6 and the adapter flange 11 comprehensive adapter shown in section. Together - and thus reusable within the kit - is the adapter flange 62 by means of connecting screws 60 with the housing of the adapter part 5 or 6 connected.

In 5 is the cylindrical shaft end of the rotor shaft 2 by means of the clamping ring 61 with the motor-side coupling half 58 connectable, which for this purpose has a slot which the clamping action of the clamping ring 61 makes predictable and definable. The transmission-side adapter shaft 52 the adapter has a center hole 51 on and is with a Aufsteckritzel 53 connected. The adapter shaft 52 is by means of the shaft seal 54 against the case 56 of the adapter part 5 sealed and by means of bearings 55 . 57 stored in this, the bearing 57 is executed sealed and thus a certain seal of the lubricant, especially grease or fluid grease, is reached towards the engine. Towards the transmission, in particular to its interior with a different lubricant, such as oil or the like, is the seal by means of the shaft seal 54 reached. Between shaft seal 54 and bearings 55 is an annulus with lubricant, especially grease or fluid grease, partially filled and thus a supply volume for lubricant available.

The transmission-side coupling half 50 is with the adapter shaft 52 connected, in particular form, force and / or material fit. The metal bellows is at its axial end portions in each case with the transmission-side coupling half 50 and the motor-side coupling half 58 welded. He transfers thus the entire torque. The use of this metal bellows 59 comprehensive adapter thus provides a geared motor with low torsional stiffness available. Because of the large mass of the rotating parts, especially the adapter, then this geared motor also has a high moment of inertia or inertia. The interface of the adapter to the gearbox is designed as a so-called open fitting and therefore allows small relative radial displacements. Thus, when inserting the pinion 53 in the transmission 7 the sprocket 53 itself and the adapter shaft 52 as well as the case 56 of the adapter part 5 fixed in that position and orientation, essentially by the position of the gearing parts of the transmission 7 is predetermined. Therefore, the transmission is already adjustable during production and the connection of the adapter does not disturb the settings of the transmission. Small production-related deviations are thus by moving or twisting the adapter shaft 52 balanced in the room. It is also essential that the setting of the center distance and thus also the game of the driving spur gear of the transmission 7 is adjustable by means of radial Move the housing 56 against the housing of the gearbox 7 , The shifts mentioned are on the order of one or more tenths. The game is in this case adjustable so that it is less than 3 minutes of arc.

The adapter flange 62 on the other hand, the engine has such an interface that the engine, including the rotor shaft 2 when screwing to the adapter flange 62 is precisely positioned, ie that the spatial position and orientation of engine end shield 13 with motor housing 1 and rotor shaft 2 is determined by screwing. This is the adapter flange 62 fitted at its interface with a fitting and the engine end shield 13 with a corresponding shape. Radial and axial deviations from the ideal position of the metal bellows 59 on

The engine has components made of different materials. For example, the stator, in particular also the motor housing 1 made of aluminum, the rotor, in particular the rotor shaft, made of steel. This results in different thermal expansions, which also act in the direction of the adapter. To compensate for these dimensions, the motor-side coupling half 58 and the transmission-side coupling half 50 an axial distance of about one or several millimeters from each other. For thermally induced length expansions of the rotor shaft so a compensation by means of the metal bellows 59 allows.

In 6 is the cylindrical shaft end of the rotor shaft 2 by means of the clamping ring 61 with the adapter shaft 67 connectable, this purpose a slot 63 having the clamping action of the clamping ring 61 makes predictable and definable. In addition, the adapter shaft 67 in the area of the motor-side slot 63 designed as a hollow shaft for insertion of the rotor shaft. The adapter shaft 67 The adapter is equipped with a push-in pinion 69 connected, which is a center hole 68 having. The adapter shaft 67 is by means of the shaft seal 66 against the case 64 of the adapter part 6 sealed and by means of the warehouse 65 stored in this. The warehouse 65 is sealed to the engine. Between shaft seal 66 and bearings 65 is an annulus with lubricant, especially grease or fluid grease, partially filled and thus a supply volume for lubricant available.

The adapter after 6 thus provides a geared motor with high torsional stiffness available. Because of the lower mass of the rotating parts, especially the adapter, compared to the adapter according to 5 then this geared motor also has a low moment of inertia or inertia. The interface of the adapter to the gearbox is designed as a so-called open fitting and therefore allows small relative radial displacements. Thus, when inserting the pinion 69 in the transmission 8th . 9 or 10 the sprocket 69 itself and the adapter shaft 67 as well as the case 64 of the adapter part 6 fixed in that position and orientation, essentially by the position of the gearing parts of the transmission 8th . 9 or 10 is predetermined, in particular by the planets of the driving planetary gear stage of the transmission 8th . 9 or 10 , Therefore, the transmission is already adjustable during production and the connection of the adapter does not disturb the settings of the transmission. Small production-related deviations are thus by moving or twisting the adapter shaft 67 balanced in the room. In particular, because of the use of the pinion 69 as a sun gear of the driving gear stage 8th . 9 or 10 is the volume of space for moving the pinion 69 when plugging in the gearbox 8th . 9 or 10 highly limited. However, the open fitting allows for the exact final relative position of the housing of the adapter part 6 and the housing of the transmission 8th . 9 or 10 each other adapts to the predetermined by the planetary position of the sun gear.

The adapter flange 62 on the other hand, the engine has such an interface that the engine, including the rotor shaft 2 when screwing to the adapter flange 62 is precisely positioned, ie that the spatial position and orientation of engine end shield 13 with motor housing 1 and rotor shaft 2 is determined by screwing. This is the adapter flange 62 fitted at its interface with a fitting and the engine end shield 13 with a corresponding shape.

To compensate for thermal expansion shims are elastic rings in the area of the bearing 65 brought in. Thus, thermal expansions are substantially at the Einsteckritzel 69 passed and in gear 8th . 9 or 10 Compensated because sun and planet are mutually slidable by small amounts without significant loss of function. The gear 8th . 9 or 10 provides space volume available, which is provided axially in front of the upper and behind the lower end face of the sun gear, as well as the 12 and 13 can be seen.

Significant difference between the adapters after 5 and 6 is that the adapter after 5 two camps 54 . 57 for the adapter shaft 52 has, for the adapter shaft 67 but only one camp 65 is provided. The warehouse 65 is essentially intended as a fixing aid when mounting. Because the sprocket 69 As a sun gear is used, no transverse force absorption is necessary. The adapter after 5 but is for assembly with the driving spur gear of the transmission 7 provided, wherein then lateral forces on the Aufsteckritzel 53 act by the camps 55 . 57 be recorded.

In 7 is the transmission 7 shown, ie the angular gear, which has the same interface with open fitting to the engine as the planetary gear. Thus, so is the engine with its engine end shield 12 both connectable with the angular gear 7 as well as with one of the planetary gears 8th . 9 . 10 , In 7 is the interface with open fitting 74 shown in more detail.

Further, then a relative radial displacement of the housing is made such that the desired size of the game of the spur gear of less than 3 Angle minutes is reached. Finally, the connection is secured permanently with connecting screws.

The advantage here is that not only the adapter with adapter part 5 , but also a direct attachment of the engine by means of the engine end shield 12 is possible, in which case the Einsteckritzel or Aufsteckritzel directly to the rotor shaft of the rotor 3 or 4 is provided. Thus, a very compact design is achieved, which is also compatible with the standard motor, comprising the rotor shaft 2 with cylindrical shaft end, over the adapter.

The sun gear is engaged with the planetary gears 86 and is significantly co-determined in the connection in its position and orientation. The planet wheels 86 are each about one or even two axially successively arranged needle roller bearings 85 at the planet axles 87 stored in the holes of the planet carrier shaft 81 are provided, which is a center hole 80 having. The planet carrier shaft 81 is by means of bearings 83 . 84 stored in the housing and by means of the shaft seal 82 sealed against this. The clamping nut 89 serves at its outer periphery as a running surface for the sealing lip of the shaft seal. The housing also has a recess with a plug for filling or emptying the lubricant.

In the 9 is the planetary gear 9 shown enlarged as a single part, this planetary gear has a flange block interface on the output side. In further embodiments of the invention, this interface is according to the Standard EN ISO 9409-1 designed as an industrial robot interface. The interface to the engine or adapter is again designed as an open fitting in the manner already mentioned. The connected to the rotor shaft or adapter shaft pinion, so pinion or Aufsteckritzel acts after connecting as the sun gear of the planetary gear. Thermal expansions are related to the volume of space 97 compensated. Advantageously, the volume of the space has an axial extent towards the sun gear between 0.2 mm and 2 mm. The sun gear is engaged with the planetary gears 92 and is significantly co-determined in the connection in its position and orientation. The planet wheels 92 are each about one or even two axially successively arranged needle roller bearings 98 at the planet axles 91 stored in the holes of the planet carrier shaft 95 are provided, which has a central bore, which by means of a screw plug 96 is tightly closed.

In 11 is the assembly of the angle gear 7 with the adapter part 5 and adapter flange 11 shown, the interface 74 designed as an open fitting for adjusting the clearance between the spur gear 70 and sprockets 53 ,

In 12 is the assembly of the planetary gear 8th with the adapter part 6 and adapter flange 11 shown, the interface 74 designed as an open fitting to compensate for tolerances. This is determined by the planetary gears 86 the Position and orientation of the pinion pinion used as sun gear 69 essentially with, in particular in radial alignment.

In 13 is the assembly of the planetary gear 9 with the adapter part 6 and adapter flange 11 shown, the interface 74 designed as an open fitting to compensate for tolerances. This is determined by the planetary gears 92 the position and orientation of the pinion pinion used as sun gear 69 essentially with, in particular in radial alignment.

The invention therefore makes it possible to connect IEC standard motors by means of adapters or proprietary motors without adapters to a gearbox, with the manufacturer's own motors being designed with a rotor shaft comprising a single or sprocket pinion. Thus, an extremely compact direct attachment is possible to a gearbox, which is also usable with connectable via standard motors.

Next advantageous in the invention that the adapter compensate for the thermal expansion of the rotor shaft and thus the transmission and the engine by means of the adapter are thermally decoupled.

It is also essential that both single-stage or multistage transmissions with or without drive-side output lateral force, that is to say transmissions with a driving spur gear stage or planetary gear stage, can be connected. The adapter is depending on the type of transmission with lateral force compensation, ie with adapter part 5 , or without shear force compensation, ie with adapter part 6 , executable. This results in a large number of possible variations. The adapter also has the additional function of allowing the centering of the pinion when installing in the gearbox.

In the case of the open fitting, it is essential that radial displacements between the adapter and the gear are allowed before tightening the connecting bolts, which are larger than corresponding displacements between the adapter and the engine.

In further embodiments of the invention not only the entire angular gear has a game of less than 3 Minutes, but also the planetary gear and the two-stage planetary gear, which from the planetary gear precursor 10 and the planetary gear 9 or 8th is formed.

The engine with rotor 2 can also be used as a direct drive motor ( 1 . 2 . 13 ) as well as another engine end shield 14 that then connects to the gears 127 . 128 . 129 . 130 . 131 the 10 allows, with the engine end shield 14 with the adapter 126 or with the gearbox 125 is connectable. In the 1 and 10 is a circled to graphically represent this connectivity 1 used.

The reference number of the circled 2 shows that also a direct attachment of the motor housing 1 together with the rotors 3 or 4 to the gearbox 127 . 128 . 129 . 130 . 131 is possible. So this is the motor housing 1 provided with an interface that corresponds to the interface of said transmission.

Thus, not only the standard transmission 127 . 128 . 129 . 130 . 131 usable for the motor housing, but also the servo gear 7 . 8th . 9 ,

Overall advantage for the invention, inter alia, that the number of parts in the geared motors is as small as possible, the reuse as large as possible within the kit and the covered application variants as varied as possible. In particular, both servo and standard geared motors are shown as variants.

The series is designed and executed in such a way that all servo gearboxes of the 1 have only integer translations.

In the variants after 12 and 13 the same adapter is used. However, the planetary gear is after 13 on both sides, the planetary gear behind 12 on one side, namely the output side, stored. Therefore, the adapter-side bearing needed 90 axial length. This length is determined by the design and axial length of the adapter shaft 67 together with the sprocket 69 considered such that the sprocket as a sun gear completely between the planetary gears 92 is used. In the 12 the same adapter is provided. So that in this planetary gear, the Einsteckritzel 69 completely back between the planetary gears 92 is inserted, is the housing 801 of the planetary gear so extended that the interface 74 , So the open fitting, in turn, at a corresponding axial position relative to the planetary gears sitting as well as in 13 , This is in 12 between the planetary carrier shaft 81 and the open Einpass an enlarged volume of air formed, which contributes to the reduction of air pressure with temperature increase. This reduction in air pressure is particularly advantageous during assembly or during temperature increases during operation. Overall, therefore, because of the set goal of the largest possible combinatorics an increased overall length in a variant of the series accepted. Surprisingly, however, an overall advantage can be achieved, namely the reduction in air pressure when the temperature increases relatively to a smaller volume of the transmission. This advantage is particularly important in servo gearboxes, because there high speeds can occur during a positioning task, which can lead to corresponding warming. Therefore, in the present series, the mentioned increase in length surprisingly accepted consciously, so as to achieve two advantages, first, namely the combinatorial diversity and, second, the reduction in air pressure.

In 12 is compared to 13 to clearly see the increased air volume. If, instead of the adapter, a motor with A-end shield is directly attached, the volume of air is likewise formed in an analogous manner.

In further embodiments of the invention, instead of the two-stage angle gear 7 a single-stage hypoid gear provided. It is advantageous that the ratio is integer, although the efficiency is slightly smaller.

In the case of the direct attachment mentioned above, it is particularly advantageous that no coupling is required and therefore the number of parts and thus also the costs are reduced. In addition, the design is therefore also compact.

The compensation of the thermal expansion takes place at 5 by means of the deformation of the metal bellows, in which 6 by means of sliding bearings 65 ,

The angular gear 7 is always designed so that it has an integer integer number overall advantageously in the range of 3 to 30 , To achieve the various gear ratios, the gearing parts are replaced within a size; In this case, depending on the desired gear ratio, a set comprising flat-toothed wheel and hypoid pinion, against a second set, comprising another flat-toothed wheel and another hypoid pinion, replaced. In addition, the spur gears of the driving gear stage are varied so that overall there is always an integer ratio. The variation of the spur gears includes at constant center distance, ie within a respective size, the helix angle and the profile displacement.

For the hypoid stage of the angular gear 7 the first sentence is advantageously designed for the ratio i = 3, the second sentence for the ratio i = 7.5.

The particularly advantageous generated gear ratios within a size that cover as wide as possible and dense occupied range of translation numbers with as few different gearing parts are i = 3, 4, 6, 8, 10, 15, 20, 25, 30, 35 and 40 In this case, the translation numbers from i = 3 to 10 are generated by means of the hypoid set with i = 3, and the remaining translation numbers are generated by the sentence with i = 7.5.

An advantageously designed series comprises 6 sizes, ie 6 different center distances at the helical gear stage of the angular gear 7 , This number covers all industrially common sizes or performance classes. In addition, an optimal ratio between variety of parts and quantities is achievable. For even larger sizes, for example in the megawatt range or more, the numbers are so small that the advantage of multiple use of parts in different variants is low, but increase the conceptual disadvantages, such as the amount of material and thus the cost of materials for the housing.

The sizes are designed such that the maximum transmissible torque of the sizes is graded in the manner M1 * (2 ^ (n-1)), where n is the size numbered from 1 to 6 and M1 is the maximum transmissible torque of the smallest size, So for n = 1.

In further embodiments of the invention, deviations from said formula M1 * (2 ^ (n-1)) are advantageous if they are less than 18%. This has proved to be a particularly advantageous value.

In further embodiments of the invention, the value M1 = 40 Nm has proven to be particularly advantageous, since thus the above-mentioned advantageous part of the market can be covered in industrial gear while maintaining the advantages mentioned.

In further embodiments according to the invention, values for M1 between 10 Nm and 100 nm have also proven to be advantageous.

In further embodiments according to the invention, the series comprises two types of low-backlash transmissions, namely the aforementioned transmissions 3 Angular minutes and similar gears, but have 6 minutes of arc. Thus, more cost-effective transmission with 6 angular minutes and corresponding geared motors can be produced and offered.
