Definitions
- the invention relates to a device and a series of devices.
- Industrial gearboxes are generally known which comprise lubricant which has to be filled or drained and replaced during assembly and / or maintenance. Therefore, many gears have a threaded hole in their housing, which are closed with a screw plug. This is space-savingly provided with a hexagon socket so that it does not protrude from the housing as little as possible.
- a fastening element with a self-tapping screw connection is known from DE 198 42 173 A1.
- a vibration sensor can be attached to the fastening element.
- the disadvantage here is that the vibration sensor cannot be screwed in, since the fastening element has a bore extending from the base body (FIG. 1 of DE 198 42 173 A1, reference number 32) to improve the elasticity of the fastening element (DE 198 42 173 A1, column 3, Lines 41-45).
- Vibration sensor is thus glued on or the like.
- the structure-borne noise to be detected must therefore pass through the screw thread and the core (DE 198 42 173 A1, reference number 22) and the adhesive connection.
- the fastening element is screwed in, chips are formed which trigger oil pollution and later also destruction of a device.
- the axial guidance when screwing in is poor because of the conical design.
- the fastener is at an unpredictable angle and depending on the angle there are different signal-to-noise ratios in the sensor signals.
- the invention has for its object to provide a compact and inexpensive transmission series, which also includes transmissions with vibration sensors and a high level of flexibility to meet customer requirements.
- the object is achieved in the device according to the features specified in claim 1 and in the series of devices according to the features specified in claim 18.
- the screw plug can be connected to the housing in a sealed manner, in particular against oil leakage, and that a second threaded hole is made in the screw plug, by means of which a sensor can be detachably connected.
- the advantage here is that a compact and inexpensive series of devices can thus be implemented, which also includes transmissions with or without vibration sensors and a high degree of flexibility to meet customer requirements. If the customer only wants one device, for example a gearbox or a geared motor, without a vibration sensor, the device is delivered with a screw plug, which is designed either according to the prior art or according to the invention. However, if the customer has a device
- Vibration sensors the sensor is screwed into the screw plug. This means that sold and delivered devices can even be quickly and easily converted or retrofitted or temporarily equipped with vibration sensors for examinations. Another significant advantage is that no additional surface of the housing has to be machined to attach sensors. Processing operations can thus be reduced.
- the invention offers particular advantages in the case of vibration sensors, since they can be connected so tightly and with high contact pressure and as directly as possible to the sound source.
- the use of threaded bores enables a good acoustic connection.
- the tightening torques of the first and second threaded holes can be made differently, the acoustic coupling of the vibration sensor to the housing can be selected very high by means of a correspondingly high tightening torque.
- the sensor itself can be connected to the second threaded hole with its prescribed tightening torque, so it is not destroyed or subjected to impermissible loads. This means that there is a high variance within the series with a good acoustic connection as a common advantage.
- the screw plug protrudes from the housing in the screwed-in state with such an excellent external shape that it can be detached or reconnected with a form-releasably connectable tool.
- the external shape is an external hexagon.
- the second threaded bore with countersink is introduced into the screw plug for releasable connection to a sensor which has an external thread corresponding to the second threaded bore and a conical section corresponding to the countersink.
- the screw plug can advantageously also be made of metal and thus a high tightening torque can be applied, as a result of which the sound damping on the second threaded bore is reduced with a reduction.
- the connection of the screw plug to the housing can be advantageously provided by means of a sealing ring.
- the senor is a vibration sensor and / or a sensor for the detection of acoustic vibrations at least in a partial range of the frequency range from 0 Hz to 10 MHz.
- the advantage here is that low frequencies, for example with a so-called knock sensor, medium and / or high frequencies with a sensor for sound or structure-borne sound, that is to say vibrations into the high ultrasound range, can be detected.
- the screw plug comprises a stop for the passage of acoustic waves and, at the same time, mechanical limitation for screwing in.
- the advantage here is that by means of the stop when applied a substantial amount of sound transmission can be realized with a correspondingly high force.
- the stop is pressed directly onto the sealing surface assigned to it and having a high surface quality. This means that there is only a low attenuation even at medium or high frequencies.
- an equally defined signal-to-noise ratio can be achieved.
- the locking screw is in contact with a sealing surface of the housing which has such a surface quality that a sealing connection between the locking screw and the housing can be produced by means of the sealing ring.
- the advantage here is that the screw plug performs the function of the sound transmission and the function of the seal at the same time. So no further components or a separate structure, such as a threaded hole in the housing and a separate screw plug, are required.
- the housing is the housing of a gear comprising a lubricant, in particular oil.
- a lubricant in particular oil.
- the housing of the transmission has a continuous threaded hole for draining and / or filling in lubricant.
- the screw plug can be used as a sealing, releasably connectable oil drain plug and at the same time can be used as sound transmission, whereby it even provides two propagation paths for sound, namely on the one hand via the screw thread and on the other hand via the stop.
- the locking screw has a cylindrical external thread for screwing into the threaded bore.
- touching surfaces, the tightening torque of the sensor against the locking screw and the tightening torque of the locking screw against the housing are designed in such a way that acoustic vibrations from both first and second threaded bores as well as via the stop can be transmitted with a sufficiently good signal-to-noise ratio for detection by means of a sensor.
- the sensor has more than one connection, that is, the connection of its external thread and its cone with the second threaded bore with a counterbore, to the housing, namely the stop and the external thread of the
- Screw plug but still a very good sound transmission, so low damping can be achieved.
- the screw plug and the housing are made of a metallic material.
- the advantage here is that a much higher tightening torque than with a plastic version, a seal with a high degree of protection and at the same time good sound transmission can be provided.
- a plastic version on the other hand, would result in a much poorer signal-to-noise ratio.
- the seal can only be compressed to the prescribed extent, since the screw plug can only be screwed in as far as it will go.
- there is a sealing surface on the housing that is to say a machined surface, which thus likewise ensures the predetermined sealing function. Due to the cylindrical design of the screw thread of the screw plug, the axial guidance is so good that the screw plug is not at an angle in the housing.
- a defined surface can be provided by means of the stop, which results in a defined pressing, because the screw plug can only be screwed in as far as the stop. This means that a well-defined signal-to-noise ratio can also be achieved.
- the screw plug can be released and screwed in again without substantial loosening or the like occurring. When screwing in, there is no chip formation that could lead to contamination or destruction.
- the stop advantageously also provides protection for the sealing ring against the environment.
- the sealing ring 4 is provided in such a way that it is increasingly compressible during screwing in up to one determined by the stop Maximum value.
- the sealing ring 4 can be positioned between two sealing surfaces (3, 7), the normal direction of which to the axial direction of the
- Locking screw thread is parallel, and when screwing in, the distance between these sealing surfaces (3, 7) can be reduced to a value determined by the stop 5.
- the advantage here is that the sealing ring is loaded as little as possible. In particular, it is increasingly compressed only between the sealing surfaces during screwing in and is not pulled and / or squeezed along the inner wall of the first threaded hole.
- Essential features of the invention in the series of devices are that the series comprises at least two sizes that include different locking screws and that the same sensor can be connected to this different locking screw in the at least two sizes.
- the advantage here is that the series has a wide variety to satisfy customer requests and at the same time is extremely cost-effective, space-saving and quick and easy to manufacture.
- the senor with its external thread can be releasably connected to the threaded bore of the screw plug.
- the advantage here is that all screw plugs for different sizes can be equipped with the same threaded hole and thus the sensor can be used with all these sizes.
- the threaded hole for connecting to the sensor and the outer shape, in particular the external hexagon are of the same design in at least two sizes of the screw plug, and the external thread, the stop and / or the sealing ring are of different types in these sizes.
- the advantage here is that with different sizes, the same tool for tightening or loosening the locking screw, the same tool for tightening or loosening the sensor and still different sizes of the devices, in particular different wall thicknesses of the housing of the gearbox or geared motor, for the same sensor are usable.
- Second sealing surface first threaded hole with internal thread, continuous
- a second threaded bore 2 with a counterbore is made in the screw plug 1 for connection to the sensor (31, 32, 33).
- the screw plug 1 is screwed with its external thread 6 into a first threaded bore 8 with an internal thread through the housing until the stop 5 is in contact. After applying a corresponding tightening torque, the sound is transmitted very well via the stop 5 and the second sealing surface 7.
- the sensor is shown schematically in FIG.
- the sensor has an external thread 31 for screwing into the second threaded bore 2 with a countersink, the cone 32 or conical section of the countersink in the second threaded bore 2 being shaped accordingly.
- the sensor has an external hexagon 33 for positive, releasable connection to a tool for tightening, such as a hexagon.
- Figure 2 shows the screw plug in the installed state.
- the sealing ring 4 is squeezed and the stop 5 rests directly on the second sealing surface 7 with sufficient force, which contributes significantly to the sound transmission.
- the gearbox series has several sizes. Since the wall thicknesses of the associated housings are different, the locking screws are also dimensioned accordingly.
- FIG. 4 shows three locking screws that match three sizes of the series. On the housing side they are designed differently, in particular with the different diameters d, c2 and c3. On the sensor side, however, they are identical, in particular with the same external dimension a and the same diameter of the threaded bore b. Firstly, the external shape is designed as the same external hexagon and secondly, the second threaded hole with countersink is also designed identically. This means that the same sensor can always be connected.
- the series therefore has a high variance or variety, satisfies customer requests for gearboxes of various sizes with or without a sensor, and even requires only one sensor for different sizes.
- the screw plug is, so to speak, an adapter that enables the use of a sensor for several sizes.
- the screw plug can also be used as a sealing element without a sensor.
- a significant advantage in the configuration of the screw plug 1 in FIG. 1 is also that the stop 5 can be used as a means of checking the connection of the screw plug to the housing because of its function of passing sound. This is because the sound conductivity increases rapidly when the screw plug is screwed into the housing after the stop comes into contact with the sealing surfaces. A faulty, in particular incomplete screwing in of the screw plug can thus be detected by means of the sound detection of the sensor.
