Description

[0001] The invention relates to an arrangement and a method for producing an arrangement for adjusting an axle distance

[0002] A tensioning device for a V-belt drive is known from DE 77 03 394 U1.

[0003] A device for mounting a motor is known from US 67 05 581 B2.

[0004] An engine mount is known from US 19 82 682 A.

[0005] A rocker table for a drive machine is known from JP 2002- 0 61 724 A.

[0006] The invention is therefore based on the object of developing an arrangement and a method for producing an arrangement for adjusting an axle distance, wherein the arrangement should be easy to operate and manufacture and cost-effective.

[0007] According to the invention, the object is achieved by the arrangement according to the features specified in claim 1 and by the method for producing an arrangement according to the features specified in claim 8.

[0008] Important features of the invention in the arrangement for adjusting an axial distance between a rotor shaft of a motor and a shaft of a gearbox are that the motor is arranged on a rocker plate which is connected to the gearbox via a rotary joint, wherein a circular hole is formed on the rocker plate into which a cardan shaft section engages.

[0009] The advantage here is that, on the one hand, the rocker plate forms a base plate for supporting the motor, and, on the other hand, the angle adjustment and thus the axle distance adjustment are made possible by the rocker plate. This allows the rocker plate to perform two functions. Furthermore, the circular hole allows the swivel joint to be directly integrated into the rocker plate, making it a part of the joint. The joint is thus directly integrated into the rocker plate.

[0010] In an advantageous embodiment, the drive shaft section is formed by an axial section of a screw. This is advantageous in that the joint is easy to manufacture. Only one screw needs to be inserted and a nut, along with a corresponding lock nut, is screwed on for axial securing.

[0011] In an advantageous embodiment, the circular hole is formed by laser cutting. The advantage here is that the contour and the circular hole are formed in a single operation.

[0012] In an advantageous embodiment, the contour and recesses of the rocker plate are formed by laser cutting and / or parts of the rocker plate are manufactured by bending. The advantage here is that the functions can be integrated into the rocker plate by simply cutting and bending.

[0013] In an advantageous embodiment, a threaded rod is provided for adjusting the angle of the swivel joint, onto whose threaded portion a first part, in particular a nut, is screwed, on which the rocker plate rests. The advantage here is that changing the distance can be carried out simply and cost-effectively.

[0014] In an advantageous embodiment, on the side opposite the first part, another part is screwed onto the threaded area of ​​the threaded rod, in particular for securing the rocker plate. The advantage here is that the rocker plate rests easily on the part, which can be, for example, a nut, i.e., a screw nut.

[0015] In an advantageous embodiment, the threaded rod is connected to the gearbox housing via a swivel joint. This allows for easy adjustment of the center distance using inexpensive parts.

[0016] In an advantageous embodiment, the rocker plate has a wall thickness between 1 and 25 mm, in particular between 10 and 20 mm. This allows for laser cutting while still providing a stable base plate for the motor.

[0017] In an advantageous embodiment, a further circular hole is provided into which the cardan shaft section engages. This circular hole is provided in a support part that is welded to the rocker part or is bent from the rocker plate. It is advantageous that two parallel holes can be provided to accommodate a cardan shaft section.

[0018] In an advantageous embodiment, transport lugs are formed on the rocker part, particularly by cutting and bending. This is advantageous because stable transport lugs can be formed for transporting the entire assembly without the need for additional parts.

[0019] In an advantageous embodiment, a first part comprising a thread, in particular a nut, is welded to the rocker part, wherein a second part having a counter-thread is screwed into the first part and an end region of the second part presses on the motor housing or the base region of the motor housing, in particular for moving the motor on the rocker plate, In particular, the second part is a screw aligned parallel to that portion of the surface of the rocker plate on which the motor is displaceable. It is advantageous that a displacement function can also be performed on the rocker plate. This allows the motor to be positioned in such a way that the alignment of the wheel connected to the belt can be effected, i.e., the alignment of the rotor shaft to the plane containing the belt can be effected.

[0020] Important features in the method for producing an arrangement for adjusting an axial distance between a rotor shaft of a motor and a shaft of a gearbox are that the motor is arranged on a rocker plate which is connected to the gearbox via a rotary joint, where - in a first step, a contour and recesses of the rocker plate are cut out, in particular by means of a laser, wherein one of the recesses is a circular hole, in particular a circular hole, - in a second step, a part of the rocker plate is bent away from a remaining part of the rocker plate, - in a third step, a support part having a circular hole is aligned with the circular hole of the rocker part by means of an aid, - in a fourth step, the support part is welded to the rocker part or is made by bending from the rocker plate, - in a fifth step, the rocker part is connected to the gearbox via a rotary joint, wherein a drive shaft section is guided through at least one of the holes.

[0021] The advantage here is that the functions of the base plate for the motor and the displacement of the motor as well as the support function for the entire drive, comprising gearbox, electric motor and belt, can be integrated into the rocker plate, whereby the manufacturing process includes a cost-effective cutting process and a bending process.

[0022] In an advantageous embodiment, transport lugs are also formed in the second step by bending sections containing recesses. The advantage here is that no additional parts are required, but a simple manufacturing process allows the additional function to be integrated into the rocker plate.

[0023] In an advantageous embodiment, a nut is welded to the rocker plate, into which a screw can be screwed, allowing the motor to be moved on the rocker plate. This is advantageous because it allows for easy movement of the motor and thus alignment. Cost-effective standard parts, namely nuts, are used. Two-dimensional movement is possible by means of two such nuts or parts welded to the rocker plate.

[0024] Further advantages emerge from the dependent claims. The invention is not limited to the combination of features in the claims. Further possible combinations of claims and / or individual claim features and / or features of the description and / or the figures will become apparent to those skilled in the art, particularly from the problem and / or the problem posed by comparison with the prior art.

[0025] The invention will now be explained in more detail with the aid of illustrations: In the Fig. 1 shows a motor rocker according to the invention for a V-belt drive. In the Fig. 2 shows a corresponding side view. In the Fig. 3 shows an enlarged section of an oblique view of the joint. In the Fig. 4 shows the rocker plate 1 of the motor rocker before bending. In the Fig. 5 shows the finished rocker plate 1, to which a support part 51 is welded. Fig. 6 shows the rocker plate 1 from an oblique view with a different viewing direction.

[0026] In the V-belt drive according to the invention, a motor 10, in particular an electric motor, drives a wheel 11 with its rotor shaft, to which a V-belt (not shown) is non-positively connected, which drives a wheel 12, which in turn is positively connected to the input shaft of a transmission 9.

[0027] The motor 10 has a motor base 14 on its housing, which is formed integrally with the housing and is mounted on the rocker plate 1, i.e., the motor rocker plate. A screw connection is provided for connection to the rocker plate. The connecting screws pass through recesses in the motor base and the motor rocker plate, which have a larger diameter than the outer diameter of the connecting screws. Thus, the motor 10 can be moved to a certain extent on the rocker plate 1 as long as the screw connection is still loose, i.e., the nuts on the connecting screws are not yet fully tightened.

[0028] The motor 10 is moved by screws 15, each of which is threaded through a nut 13 and presses with its axial end against a side surface of the motor base 14. The nuts 13 are integrally connected, in particular welded to the motor rocker plate, with the screw axis parallel to the surface area around the welded joint on the motor rocker plate. When using hexagon nuts 13, an outer surface of the hexagon is welded to the motor rocker plate. This compressive force allows the motor to be moved on the motor rocker plate.

[0029] The rocker plate 1 has a wall thickness between 1 and 25 mm, in particular in the range of 10 to 20 mm.

[0030] To adjust the tension of the V-belt, the rotor shaft of the motor 10 is guided through a slotted hole in the rear wall of the spacer plate 7, designed as a belt cover, thus allowing a change in the center distance between the wheels (11, 12). The rear wall of the spacer plate, designed as a belt cover, is screwed to the gearbox 9.

[0031] To raise or lower the motor, a joint is arranged between the rocker plate 1 and the gearbox 9. For this purpose, the screw 2 is guided through a circular hole 40 in the rocker plate and through a hole in the gearbox housing or through a hole in a part connected to the gearbox housing.

[0032] A smooth, cylindrical portion of the connecting screw contacts the circular hole 40 and the borehole. At its axial end, the connecting screw has a threaded portion onto which a nut with a corresponding lock nut is screwed. This simply forms a swivel joint.

[0033] Opposite, the angle of the rocker plate 1 relative to the horizontal or the gear 9 is adjusted by a threaded rod 4 provided via a swivel joint on the gear housing. The swivel joint provided on the gear housing has the screw 8.

[0034] The threaded rod 4 is guided through a recess in the rocker plate 1. A nut 5 is screwed onto the threaded rod 4, on which the rocker plate 1 rests. The height of the support point can be adjusted by turning the nut 5. A nut 6 located on the other side of the rocker plate 1 secures the rocker plate 1 after the adjustment process.

[0035] Transport eyes 3 are also formed on the rocker plate 1.

[0036] When transporting the drive by using the transport eyes 3 as a suspension point, for example on a chain or a hook, the nut 6 secures the gear 9 against falling down, since at least part of the weight of the gear flows through the joint with the screw 8 via the threaded rod 4 and the nut 6 to the rocker plate 1.

[0037] A support part 51 is also welded to the underside of the rocker plate 1, which has a further circular hole 50 for the swivel joint, so that the swivel joint is supported on at least two circular holes connected to the rocker plate 1.

[0038] The rocker plate 1 is manufactured by laser cutting the contour from a flat solid plate. The support part 51 is also laser cut from a plate.

[0039] Subsequently, the circular holes (40, 50) as well as the holes for the transport eyes 3 are cut out of the rocker plate 1. Likewise, a recess contour is cut out, which enables subsequent bending of a partial area to form the transport eyes 3.

[0040] In the next step, sections of the rocker plate 1 are bent. This creates the transport lugs 3 on the one hand, and a side wall 52 with a circular hole 40 is bent vertically on the other.

[0041] The support part 51 is then welded to the rocker plate 1, whereby before welding a round body, such as a tube or round bar, is guided through the circular holes 40 and 50 and inserted for the precise alignment and centering of the support part 51.

[0042] After welding and removing the round body, the rocker plate 1 is connected to the gear 9 using the screws 2.

[0043] The rocker part 1 thus not only performs the function of adjusting the height of the motor 10, but the transport eyes 3 provided on it also provide a means of transporting the entire V-belt drive.

[0044] Furthermore, the design of the swivel joint on the rocker plate 1 can be integrated.

[0045] Advantageously, not just one threaded rod is provided as described, but two such threaded rods spaced apart from each other. This allows for alignment of the rocker plate.

[0046] Likewise, at least two nuts 13 welded onto the rocker plate 1 are used to enable pressure to be exerted on the motor base 14 by means of two screws that are perpendicular or at least not parallel to each other. spatial alignment of the rotor shaft to the plane containing the belt, i.e. not only a one-dimensional pivoting movement when actuating a screw part screwed into a welded nut, which presses on the motor base 14.

[0047] Each nut is assigned a parallel-oriented nut. In further development, nuts with opposite orientations can also be provided on the opposite side.

[0048] Fig. 6 shows the rocker plate 1 from an oblique view with a different viewing direction.

[0049] Recesses 60 for screw heads are provided in the rocker plate 1. This means that only a small distance is required between the screw thread and the rocker plate 1. Two nuts 13 are aligned parallel and each assigned to the same foot side.
