Definitions
- the invention relates to a Gleitkeilgetriebe having an elliptical drive pulley as a drive, wherein the elliptical drive pulley is arranged concentrically in a flexible and an outer toothing having reduction ring, further wherein the flexible reduction ring is arranged concentrically in an inner toothing having an outer wheel, according to the features of the preamble of claim 1.
- Such a Gleitkeilgetriebe also known as stress wave transmission or Harmony Drive
- It is a transmission with an elastic transmission element, which is characterized by a high translation and rigidity.
- the sliding wedge gear consists of three elements: An elliptical drive pulley, a deformable cylindrical reduction ring, which serves as a drive in the prior art.
- a rigid cylindrical outer wheel is present, wherein an outer toothing of the reduction ring has fewer teeth than the internal toothing of the outer wheel.
- the invention is based on the object, such a wedge gear for certain applications, in particular for use with sensors, preferably for detecting rotational movements of a measurement object to apply and improve.
- the output via the outer wheel takes place (in contrast to the sliding wedge of the prior art, where the output via the reduction ring takes place), wherein further the reduction ring is fixed and arranged.
- the reduction ring is not relatively movable to the drive pulley or to the outer wheel and thus the transmission of movement and in conjunction with the outer toothing of the reduction ring and the inner toothing of the outer wheel takes over the reduction between the drive side and output side of the Gleitkeilgetriebes.
- the outer wheel cooperates with a sensor arrangement or, alternatively, is formed as a component of a sensor arrangement, a measurement object whose rotational movement is to be detected by the sensor arrangement being connected to the drive disk.
- Another advantage of the Gleitkeilgetriebes invention is the fact that the transmission structure is self-locking and backlash, so that due to the transmission of the rotational movement on the sensor assembly can not give Messvertigschept due to a game in the transmission, just as movements of the measurement object the sensor arrangement transmitted due to the self-locking of the sliding wedge gear.
- the slide wedge gear is arranged in a housing, wherein the reduction ring is fixedly formed and arranged on the housing.
- the Gleitkeilgetriebe preferably with a sensor assembly, completely and protected as a module is housed in the housing, wherein the housing may also have a connector or a cable for taking out the signals of the sensor assembly.
- This modular design also has the advantage that such a compact sensor arrangement can be manufactured and tested by a manufacturer in order to achieve a high resolution in the implementation of the rotational movement of a measurement object, after which the delivery to the user of the sensor arrangement takes place this module without much effort
- a compact sensor in vehicle technology, in which e.g. in passenger cars, rotational movements such as e.g. a tailgate or an actuator (for example, an electric motor) performs for the steering of a vehicle, detected and converted into an electrical output signal.
- rotational movements such as e.g. a tailgate or an actuator (for example, an electric motor) performs for the steering of a vehicle, detected and converted into an electrical output signal.
- the reduction ring is fastened fixedly to the housing by means of a latching connection, a welded connection or by means of an adhesive connection.
- a latching connection e.g. a welded connection
- an adhesive connection e.g. a welded connection
- a latching connection has the advantage that the reduction ring due to a corresponding shape of the locking means (latching hook and from this to hinterelecommunicationder paragraph or recess) can already be realized with the production of the elements involved and a simple assembly of the associated elements is given.
- an elliptical drive disk 1 is shown at the bottom left, which concentrically in its center a receiving opening, e.g. receives for a drive shaft, wherein the drive pulley 1 is connected via this shaft with the measurement object or wherein the shaft is a part of the measurement object.
- the elliptical drive disk 1 itself is a component of the measurement object.
- the Gleitkeilgetriebe is arranged in a housing 4, wherein schematically shown that the housing 4 is pot-shaped.
- the housing 4 is pot-shaped.
- sensor elements On the side walls of the cup-shaped housing 4 are sensor elements, these sensor elements in interaction with the rotatable outer wheel 3 in a drive of the drive pulley 1 generate an electrical output signal.
- This electrical output signal is led out of the housing 4 via connectors or cables, not shown here, and can via a downstream electronic unit
- the output signal generated and output by the sensor arrangement is already processed or converted prior to being led out of the housing 4, e.g. is to think of an analog-digital conversion.
- it may be an active sensor arrangement with electronics within the housing 4, wherein within the housing 4, a power supply is housed or via cables from the outside, a power supply is supplied.
- the reduction ring 2 has a first ring with external teeth 21, wherein spaced from the first ring, a base ring 22 is provided, which has at least one web, preferably four Webs 23, is connected to the first ring of the external toothing 21.
- This structure in particular made of plastic, preferably an injection-molded plastic, has the advantage that on the one hand durability of the reduction ring 2 is ensured, on the other hand, the first ring with the external teeth 21 can be deformed without disadvantages of the elliptical drive pulley 1, about their rotational movement over to transmit the external teeth 21 to an internal toothing 31 of the outer wheel 3.
- the base ring 22 is flattened, so that thereby a compact construction of the reduction ring 2 can be achieved and on the other hand, the reduction ring 2 can be attached flat to the housing 4, in particular the cup-shaped bottom of the housing 4 or its housing cover.
- the tooth shape can be from a certain module over square to round.
- the reduction ring 2 is secured against rotation (in particular by a support on the housing 4) and is only in the region of the external toothing 21, which is arranged on the first ring, deformed.
- the outer wheel 3 is connected to a further (not shown here) elliptical drive pulley or is part of another elliptical drive pulley of a further downstream Gleitkeilgetriebes.
- a further (not shown here) elliptical drive pulley or is part of another elliptical drive pulley of a further downstream Gleitkeilgetriebes This means that the stocky outer wheel 3 of a first slip wedge gear can already be used as another elliptical drive part (drive pulley) for the next reduction stage of another Gleitkeilgetriebes.
- first and a second downstream Gleitkeilgetriebes is a two-cascaded Gleitkeilgetriebe, with more than two cascaded Gleitkeilgetriebe can be used, which is particularly advantageous when extremely high reductions and consequently extremely accurate resolution requirements placed on the sensor assembly become.
- the housing 4 is shaped in accordance with the design of the sliding wedge, but this does not necessarily have to be so, so that other, for example, angular shapes of the housing 4 are just as conceivable as more complex outer geometries of the housing to this adapt to the desired installation location.
- the Gleitkeilgetriebe can also be installed directly at its installation location, so that the area in which the Gleitkeilgetriebe is installed at the installation, serves as a housing.
