Description

System of combinable angular gears

DESCRIPTION

Technical area

The present invention relates to a system of combinable and very inexpensive to produce with rigid and / or adjustable Achswinkeln (hereinafter also referred to as deflection), housing parts, bearing pieces and extensions, for uniform and low-loss transmission of rotational movements over long and complicated tortuous paths ,

State of the art

[0002] Bowden cables are already known from the prior art for transmitting mechanical movements over long and flexibly displaceable paths. DE3905633 and US7,267,032 disclose a wrenching tool having an angular gear with a rigid axle angle and a plurality of angularly bent and hardened cylindrical angle pins. The angle pins here consist of bent steel wire and have a constant cross section.

[0003] Furthermore, cardan joints and bevel drives for deflecting rotational movements generally belong to the state of the art, as do torsion shafts and flexible shafts made of wound steel cables.

The disadvantage is that for uniform and low-loss transmission of rotational movements over long and multiple tortuous paths, combinations of multiple angle gears with intermediate extensions are very expensive to manufacture. Therefore, Bowden cables are usually used for such tasks. Bowdenzugseile

CONFIRMATION COPY But especially in large series applications are very often cause of failures. Expensive, because very finely stranded ropes and / or extensive protection against buckling of the steel cable, in order to prevent the breakage of the individual strands are then necessary, which also proves to be expensive and above all difficult to prove by tests. Many misses and causes of failure must be theoretically considered and excluded. Remedial measures must be tested for effectiveness in each application. Many influences from the field are difficult to predict.

Further disadvantages of the already known solutions are:

[0006] a) If a gimbal is used as an angle gearing, gimbal errors result in the translation. Quality assurance systems for

Monitoring of torques must therefore not be used in combination with cardan joints.

B) The more complex the laying path of a Bowden cable, the worse its efficiency. The efficiency depends exponentially on the coefficient of friction of the cable and on the total deflection angle of the Bowden cable installation. These values are subject to high tolerances and are themselves dependent on many influencing factors such as lubrication, wear, icing conditions, changes in the laying path and other influences.

C) The laying track should not lead to a large Gesomtumlenkwinkel the rope because of the efficiency. If this sum of all deflection angles becomes too great, the efficiency drops exponentially. For example, emergency actuators for locks in a vehicle can reach impermissible values so quickly. The laying track can therefore only have a limited complexity. A total deflection angle of 180 degrees is often considered critical. D) A Bowden cable itself usually consists of at least seven components and thus has at least seven assembly processes. Rope and support hose are complex to manufacture and therefore expensive. On average, one can assume 14 cost-relevant individual positions.

E) Simple bevel gear often have only one or two supporting teeth and therefore can only transmit small moments or require a correspondingly large space. The meshing bumps always make disturbing noises. Axial angle tolerances and other toothing tolerances must often be maintained within narrow limits. Achswinkel are usually not variably adjustable.

[001 1] f) Bowden cables and flex shafts can only be laid in very large minimum bending radii, because otherwise, especially in the course of time, cable breaks will occur. Such errors are often not detectable for quality assurance prior to delivery and can no longer be detected later as the cause of the error.

G) Large Verlegeradien are often not possible due to lack of space.

Presentation of the invention

The present invention is therefore based on the object to provide a system of stable, combinable and very inexpensively producible angular gears with rigid but also with variably adjustable deflection angles, extensions, bearing pieces and housing parts, which is suitable for Bowden cables irrespective of the overall wrap angle of the laying track, to provide high efficiency with constant reduction and low functional costs.

According to the invention the above object is achieved with the features of claim 1. Thereafter, a system of Umlenkgetrieben and extensions of the type mentioned above is characterized in that the components for the deflection gear with rigid deflection angle, as well as for the deflection gear with variable deflection are designed so that drives, angle pins, drives, bearing pieces, extensions can be produced together and partially assembled in a modular tool for a two-component casting process.

In a particularly advantageous embodiment of the invention acting on at least one drive on the angle pins forces to drive the angle gear. The forces may be compressive forces, magnetic forces or forces originating from shape memory alloy components.

[001 7] For variably adjustable deflection gear inserts must be inserted into the tool. In this case, in the first step of the casting process, the drive and the output of the gear are produced in a refractory material. A refractory material is always understood to mean a material whose expansion temperature is higher than the processing temperature of the low-melting material used.

The drive has a positive connection, which fits the positive connection of at least one output and / or at least one extension. This positive locking can be designed with coding ribs so that it fits only to a single connection part or only to a certain group of connection parts.

At the same time in the first step of the casting process one or more different lengths extensions can be made, depending on the needs of each application. These extensions have a third positive connection and a thread, via which later intermediate drives can be driven both translationally and rotationally, For the second casting process, the first tool upper part is exchanged for the second tool upper part. Actuators, power take-offs, extensions and bearing pieces are still located in the tool lower part.

For an angular gear with rigid axes, the second tool upper part is used without inserts. At least one avidity arises between the drive piece, the lower tool part and the second upper tool part. In this, the low-melting material is poured, so that at least one rigid angle pin is formed.

For an angle gear with adjustable deflection an insert is inserted into the second tool shell per angle pin. The cavity for the angle pin is formed between the drive part, tool lower part, third upper tool part and insert part. The legs of the angle pin are so two-piece and form a joint; this then has a continuously variable deflection angle result. As a result, the deflection angle of the angular gear is then infinitely adjustable.

Subsequently, the parts are ejected from the tool and mounted. For each gearbox, only one drive piece has to be plugged onto a drive with its rigid or adjustable angle pins. The angle pins were already preassembled during the casting process. All parts are therefore only a cost-relevant position in the production and one in the assembly. So you could string together seven gear to come to the same number of cost-relevant positions of a Bowden cable.

The essential and decisive advantage of the proposed system of combinable and very inexpensive to produce angle gearboxes with rigid and variably adjustable Achswinkeln and extensions is thus that all parts of a transmission chain with rigid and / or flexible angle gears, extensions and bearing pieces in a single Two-stage casting process can be produced, regardless of the type and number of are adjustable, regardless of the type and number of required gears or extensions.

25

Parts for producing an open, rigid angle gear 1 and an open, flexible angular gear 5, two outputs 20, an extension 9 and a bearing piece 1 3 in an isometric view. The angle pins 23 and the inserts 1 4 are arranged in the drives l 6 star-shaped pointing radially outward. The extension 9 has a positive connection 0

The extension 10 and a thread 1 2. The angle pins 23 are made of a low-melting material 38. Drive 1 6, output 22, extension 9 and bearing piece 1 3 are made of a refractory material 37. As can be seen from Fig. L is to each drive 1 6 at least one angle pin 23 is arranged. The angle pins 23 have an angular head 24th and also have transitional regions 26 between the angle head 24 and the cylindrical leg. In addition, the angle head 24 can enclose the spherical end of an insertion file 14. In the tool position shown, all the angle pins 23 with the outward legs to the center of the drives 16 out. The advantage of this arrangement is that the angle pins 23 can be poured into the drives 1 6 and so after the removal from the tool 30 are all already pre-assembled in the drive. Another advantage lies in the fact that by inserting inserts 1 with a spherical end in the second tool upper part 34, the angle pin 23 has an adjustable deflection angle 15.

Fig. 2 shows all in a tool 32 simultaneously produced parts for producing an open, rigid angle gear 1 and an open, flexible bevel gear 5 and an extension 9 and a bearing piece 13 in a plan view. The individual tool segments 31 that can be combined with one another are shown. The cutting curves A-A and D-D are shown. The representation here is purely exemplary and does not limit the general idea of the invention. In the advantageous embodiment of the invention shown in FIG. 2, the tool can be subdivided by tool inserts 31 into tool inserts 31 which can be combined in any desired combination. The advantage of this design is that later standardized tool inserts 31 can be combined to form a new tool 30 for each application. Another advantage is due to the fact that all parts of an application, except for the housing parts 2, 3 6, 7, can be created in only one manufacturing process and in the respective required number. The parts then need to be brought to assembly after each production only set. Sorting is not required.

3 shows a section AA through the open adjustable bevel gear 5 in the tool position. The tool 30 consists of a lower tool part 32 and the first upper tool 33, through the runners 36, the drives 16, the outputs 20, the extension 9 and the bearing pieces 13 cast from a refractory material 37. As can be seen from Figure 3, the Lagersfück 13, the drive 16 and the output 20 in Werkzeugunfertei! 32 of the tool 30 and the first tool upper part 33 is arranged. These parts are poured over the sprue channels 3ό of a refractory material 37. The advantage of this design is that later the Winkelstiff 23 can be poured from a niederschrnelzenden material 38 directly into the drive 1 6.

4 shows a section AA through the open, adjustable angle gear 5 in the tool position. In the second tool upper part 34 insertion file 14 are inserted. In the lower tool part 32 are the bearing piece 13, the drive 16 of the output 20 and the extension 9. The first tool upper part 33 has been exchanged for the second tool upper part 34 with the inserted insertion files 14. The angle pins 23 surround the spherical head of the inserts 14 in the region of the angle head 24 and thus form the joint 25. Through the sprue channels 36, the angle pins 23 are cast from niederschmelzendem Werksfoff 38 in the drives 16. The drives 1 6 have clearances 19, which prevent the Anfrieb the leg of the angle pin 23 fully comprehensive. This results in rotation of the angle pin 23 and by mold release agent and by the shrinkage of the angle pin 23 a small clearance. As can be seen from FIG. 4, an insert part 14 is inserted in the second tool upper part 34 for each winkeift 23, if an adjustable bevel gear 5, 8 is to be built later with the front end 16. The angle pin 23 consists of a low-melting material 38. The drive contains clearances 19 which prevent jamming of the angle pin 23 in the drive 1. The bearing 13 and the output 20 also remain in Werkzeugunfertei! arranged. The advantage of this design is that the angle head 24 of the Winkelelfiftes 23 surrounds the spherical end of the insert 14 and thus a joint 25 is formed, via which the deflection angle 15 is adjustable. 5 shows a section DD through the open rigid win kelgetriebe 1 in tool position. In the second tool upper part 34 no inserts 1 4 are inserted. In the lower tool part 32 are the drive 1 6, the output 20 and the extension 9. Through the sprue channels 36, the angle pins 23 are cast from niedersch meltsem material 38 in the drive 1 ό. The tool change insert 35 allows it to change the length of the extension 9 to än. The thread 1 2 can either be spindled or demoulded by skewed cores. As can be seen from Figure 5, in the second tool upper part 34 for each Win kelstift 23 no insert 1 4 inserted because with the drive 1 6 later a rigid angle gear to be built. The angle pin 23 is made of a low-melting material 38, the drive also contains clearances 19, which prevent jamming of the angle pin 23 in the drive 1 6. The tool change insert 35 makes it possible to change the length of the extension 9 or to provide the extension with a thread 1 2. The thread can be spindled or demolded via diagonally running cores. The advantage of this Ausführu ng is that a rigid Win kelgetriebe 1, 4 oh ne inserts 1 4 gets along and thereby still gü nstiger is. Another advantage is due to the fact that translational intermediate drives 28 can now also be realized via the thread 1 2 of the extension 9. Another advantage lies in the fact that the Freimach ments 1 9 prevent a hydraulic cross section between the drive 1 6 and 23 Winkelsetten, thus kan n the pen can move with very little clearance. The transmission is very low backlash and tolerant nzunempfindlich.

Figure 6 shows a ready assembled, open, rigid angle gear 1 and a single Win kelstift contained therein 23 in an isometric view. On the angle pins 23, the output 20 was inserted after the angle pins 23 were rotated in one direction and moved so that their legs are now parallel. The Win kelstift has between the legs of the angle head 24, which tapers in the two transition areas 26 in the cylindrical part of the legs. The drive 1 6 has a Formsch flow 1 7 and a Codieru ng 1 8. The output 20 has a positive connection 21 and a coding 22. As can be seen from Fig.6, the output 20 is arranged on the cast-in drive 16 angle pins 23. For this purpose, the angle pins were twisted and moved so that their legs no longer point radially outward, but are parallel. This results in an open, rigid angle gear. 1 Between the two legs of the angle pin 23 of the angle head 24 is arranged. The cylindrical legs go over in a transition region 26 in the angle head 24. The drive 1 6 has the positive connection 1 7 and the coding 18. The output 20 has the positive connection 21 and the coding 22. The advantage of this embodiment is that the rigid angle gear 1 is mounted with only one assembly operation by the output 20 the angle pins 23 is inserted. Another advantage is due to the fact that increased by the shape of the angle head 24 and the thickening of the legs in the transition region 26, the support width 27 and thus the rigidity and stability of the legs is substantially improved. This leads to a higher transmissible moment Man 39.

7 shows a closed, rigid angle gear 4. An open, rigid angle gear 1 or an open adjustable angle gear 5 is arranged in a housing of the rigid angle gear 2. The housing cover 3 is arranged on the housing of the rigid angle gear. As can be seen from FIG. 7, for a closed, rigid angle gear 4 in a housing part 2, an open, rigid angle gear 1 or an open, adjustable bevel gear 5 is arranged. The mounting opening in the housing part 2 is closed by a housing cover 3. The housing of the rigid angle gear 2 has a reinforcing rib with a bore in order to fix or hang the closed rigid angle transmission 4 can. The advantage of this design is that the gearbox is now tightly sealed and can be used as a screwing or simply as an angle gear. Another advantage lies in the fact that such an angle gear has no gear noises and therefore is very quiet. Another advantage is that when using an open, adjustable angle gear 5, the deflection angle 15 of the angular gear 5 to the deflection angle 15th of the housing part 2 sets and it can not come to jamming, even with low-backlash gear.

Fig. 8 shows a ready assembled, open, angular bevel gear 5 and a single angular pin 23 contained therein with the insert 14 in an isometric view. As can be seen from Fig.8, is cast at the, in the drive 1 6. Angle pins 23 each have an insert 1 4 arranged. At these inserts 14, the output 20 is arranged. This results in an open, adjustable angle gear 5. Between the two legs of the angle pin 23 and the insert part 1 4 of the angle head 24 is arranged. The cylindrical leg of the angle pin 23 merges into the angle head 24 in a transition region 26. The angle head 24 encloses the insert 14 so that a hinge 25 is formed. The deflection angle 15 is thereby adjustable by means of the joint 25. The drive 16 has the form-fit 1 7 and the coding 1 8. The output 20 has the positive connection 21 and the coding 22. The advantage of this design is that the transmission is mounted with only one Monfagevor- gang. Another advantage is due to the fact that the stiffness and stability of the legs is substantially improved by the shape of the angle head 25 and by the thickening of the legs in the transition region 27. This leads to a higher transmissible torque Man 39. Another advantage is that the deflection angle 15 is adjustable due to the joint 25. Another advantage is due to the fact that now results in the flexible property of a Bowden cable, without having the disadvantages such as large Verlegeradien or poor efficiency.

9 shows an enlarged section through the drive 16, the angle pin 23 and the insert 14. The support strip 27 can be maximized by the design of the angle head 24 and by the transition region 26. The clearances 19 in the drive 16 prevent jamming of the angle pins 23. The drive 16 includes the angle pin 23 only in the transition region 26 full circumference. In addition, the clearance 19 prevents a hydraulic cross section between drive 1 and Angle pin 23. As can be seen from FIG. 9, the shape of the angle head 24 and the transition region 26 of the angle pin 23 considerably increase the support width 27 with respect to a bent angle pin 23 with a constant circular cross-section. The insert 14 becomes at its spherical end from the angle head 24 includes. The drive 1 6 has clearances 19, which are arranged so that the angle pin 23 is not completely covered by the drive 16. The advantage of this design is that a much higher drive torque Man 39 can be transmitted through the angle head 24 and the increased support width 27. Another advantage lies in the fact that by the clearances 19 clamping the angle pins 23 in the drive 1 6 is prevented.

10 shows a ready-mounted, closed, adjustable angular bevel 8 with a first housing part of the adjustable angular gear 6 and a second housing part of the adjustable angular gear 7. [0048] As can be seen from FIG. adjustable angle gear 8 in a first housing part for adjustable angle gear 6 an open, adjustable bevel gear 5 is arranged. The output 20 is placed on the parallel insertion parts 14. At the output 20, a second housing part for adjustable angle gear 7 is arranged. Both housing parts 6, 7 are connected to each other with a hinge so that the deflection angle 15 is adjustable. About the two housing parts 6, 7, a rubber bellows 41 is arranged. The drive 16 has the Formschiuss 17 and the coding 18. The output 20 has the Formschiuss 21 and the coding 22. The advantage of this design is that the transmission is now encapsulated and can be used as a screwing or simply as an adjustable angle gear , Another advantage lies in the fact that such an adjustable bevel gear has no gear noises and therefore is very quiet.

Fig. 1 shows an assembly of all angular gear 1, 4, 5, 8, 9 extensions and bearing pieces 13. The form-fitting 10, 1, 21 are shown in section with the codes 1 1, 18, 22. The drive torque Man 39 is partially distributed on the intermediate translatory drive 28 and partially on the rotary intermediate drive 29 and partially on the output 40. The representation is purely exemplary and does not limit the general idea of the invention. As can be seen from Fig.1, the angular gear 1, 4, 5, 8 and the extensions 9 on the form-fitting 10, 1 7, 21 initially arbitrarily arranged. By coding 1 1, 18, 22, which are attached to the form-fitting 10, 1 7, 22, this arbitrary arrangeability is limited. On the extension 9, a translational intermediate output 28 or a rotary intermediate output 29 may be arranged. About the translational and rotary intermediate output 28, 29 is a part of the drive torque Man 39 is branched off. The remaining drive torque is transmitted via a closed, adjustable angle gear 8, a further extension 9, an open, rigid angle gear 1, a closed, rigid angle gear 4 and an open, adjustable bevel gear 5 as the output torque Mab 40 and delivered. The gearboxes 1, 4, 5, 8 and extensions 9 are fastened and supported by bearing pieces 13, which can be arranged as required on the angle drives 1, 4, 5, 8 or the extensions 9. The advantage of this design is that the components by coding ribs and grooves 1 1, 18, 22 in the form-fitting ends 10, 17, 21 are clearly and correctly mounted. A misappropriation is excluded. Another advantage lies in the fact that the drive torque 39 can be distributed by intermediate drives 28, 29.

12 shows an assembly of open angle transmissions 1, 5 which has the same number of parts and process steps as a Bowden cable and is therefore approximately the same price. The drive torque Man 39 is transmitted directly as output torque Mab 40. In a further advantageous embodiment can - as Figure 12 shows - a particularly favorable combination of open, adjustable and rigid angle transmissions 1, 5 are built. The advantage of this design is that the number of manufacturing and assembly processes is equal to the number of manufacturing and assembly processes of a conventional Bowden cable. Thus, the total cost of the gear combination are the same maximum, as a Bowden cable. at a total deflection angle of 540 °, namely 6 times 90 °, the efficiency of a Bowden cable will be almost zero. However, the gearbox combination will still have an estimated efficiency greater than 70%. Another advantage lies in the required deflection radii. A Bowden cable requires much larger deflecting radii than the deflecting gear and thus also much more space. Another advantage of this transmission chain compared to a Bowden cable is the low-backlash transmission and the adjustment-free mounting. Seillängungen no longer lead to more play or even malfunctions.

The inventive system of combinable and very inexpensive to produce angle transmissions 1, 4, 5, 8 with rigid and adjustable deflection angles l S, housing parts 2, 3, 6, 7, 41, bearing pieces 1 3 and extensions 9 is limited in its Not designed for the above-mentioned preferred embodiments. Rather, a variety of design variations are possible, which make use of the solution shown even with fundamentally different type of execution.
