Definitions
- the present invention relates to a Rotationslinearan ⁇ drive with a linear drive device having a Pri ⁇ märteil and a secondary part.
- Rotary linear drives are well known.
- Rotary linear drives with external rotor for the linear drive have the advantage over rotary linear drives with internal rotor that they have the same outer diameter over a larger air gap surface, so that higher axial forces he can testify ⁇ .
- the placement of the magnetic field sensors of the donor devices is critical. They must in principle be shielded from the electromagnets or permanent magnets of the linear drive or be correspondingly far away from them.
- the object of the present invention is thus to propose a rotary linear drive with improved Gebereinrich ⁇ device.
- this object is achieved by a Rotati ⁇ onslinearantrieb with a linear drive device comprising a primary part and a secondary part, said secondary part is designed as an external rotor and a Ge ⁇ prepared direction for detecting a linear motion and / or a rotational movement is at least partially disposed in the interior of the primary part.
- the arrangement of the transducer device at least partially in the interior of the primary part can be largely shielded from the magnetic devices of the primary part. This is an enhanced quality of the encoder signals guarantees ⁇ guaranteed.
- At least one component of the transducer device is mounted on a hollow journal of the secondary part, wherein the hollow journal protrudes into the interior of the primary part.
- the movement of the secondary part is registered in the interior of the primary part.
- a stationary sensor pin can protrude into the interior of the hollow pin. As ⁇ by movements of encoder magnets can be registered, which are attached to the hollow pin.
- the hollow pin is mounted in a bore of the Primär ⁇ part.
- the transducer device is arranged on the hollow pin and thus in the vicinity of the bearing, eccentricities can be largely avoided.
- the linear motion is detected by a sensor in the sensor pin. Specifically, it may be in the Mag ⁇ Neten to a ring magnet to act, which is märspulen a cylindrical-shaped linear sensor with a secondary coil and two Pri ⁇ moved.
- a Rota ⁇ be arranged tion transducer magnet least whose rotational motion is detected by a sensor at the free end side of the sensor pin at the periphery of the hollow pin.
- the Sen ⁇ sor working inside the hollow pin is thus largely shielded from external influences.
- the primary part has a cooling device. This should insbesonde ⁇ re also cool the inner region of the primary part, so that the encoder device, but also the bearing of the hollow pin, not be heated excessively he ⁇ by the power loss of the primary part.
- the rotary linear drive shown in the figure has a rotary drive unit 1 and a Linearantriebsein ⁇ unit 2.
- a shaft 3 can move both in the circumferential direction and in the axial direction. Such movements are necessary, for example, for rolls of printing presses or for machine tools and in particular milling machines.
- the linear drive 3 is equipped with an external rotor 4, which is designed cup-shaped.
- the external rotor is with Per ⁇ manentmagneten 5 fitted on its inner circumference.
- a hollow cylindrical primary part is located in the interior of the secondary part 4 or external rotor.
- the primary part 6 is provided with windings 7. Furthermore, the primary part 6 fixed to a lid 8 of the housing 9 of the Rotationslinearan ⁇ drive rotatably connected.
- the primary part 6 has a bore into which a hollow pin 10 of the secondary part 4 protrudes.
- the hollow pin 10 is mounted in the bore of the Primär ⁇ part 6.
- the hollow pin 10 has a bore, on the inside of which rotary encoder magnets 12 are mounted.
- the axial Warre ⁇ ckung the rotary encoder magnets 12 corresponds approximately to the stroke that can perform the linear actuator 2. This ensures that a rotation signal can be obtained in the entire linear range of the drive.
- a pipe or a sensor pin 13 is also mounted rotatably.
- a rotation sensor 14 which is realized, for example, by an angle Hall sensor. This assumes rotational movements of the rotary encoder magnets 12 on the hollow pin 10 of the secondary part 4 true.
- a plastic extension tube 15 is fixed in the free end of the hollow pin 10. At the end of this extension tube 15 is an annular linear encoder magnet 16.
- the extension tube 15 made of plastic does not affect the magnetic field ⁇ of the encoder magnets 12 and 16.
- a linear sensor 17 is also accommodated in the sensor pin 13. This consists of a weich ⁇ magnetic material including a secondary coil and two primary coils. It is able to detect the linear position of the linear transmitter magnet 16 and thus the linear position of the secondary part 4.
- the extension tube 15 made of plastic does not affect the Mag ⁇ netfeld the encoder magnets 12 and 16.
- the sensor pin 13 is exchangeably fixed to the cover 8, and is thus fixed in relation to the housing 9, the windings 7 of the primary part 6 and the windings 18 of the rotary drive 1 in its position and orientation.
- the hollow pin 10 utilizes be ⁇ for the arrangement of the bearing 11, there is the advantage of an almost therefrom len idea ⁇ coaxial arrangement of the encoder magnets 12 and 16 to the sensors 14 and 17. This is a high quality of the encoder signals achievable.
- Another advantage of this arrangement of the encoder device within the primary part 6 of the linear drive 2 is the shielded position of the encoder magnets and sensors of the electromagnetic fields of the drives 1 and 2.
- the Wech ⁇ selfelder the drives 1 and 2 thus have no effect on the sensor signals of transmitter device.
- the primary part 6 of the linear drive 2 is provided with a water cooling, which is indicated by a cooling hole 19.
- a cooling hole 19 Several of these axially extending cooling bores 19 are connected to one another in the cover 8 and a further cover 20 attached to the opposite end face of the primary part 6 by meander-shaped milled webs.
- the cooling can be realized by a gueri ⁇ shaped groove which is milled into the bore of the primary ⁇ part 6. This helical groove can be covered by a sleeve, which can then simultaneously serve as an outer ⁇ sleeve of the bearing 11.
- the axial extent of the rotary encoder magnets 12 corresponds approximately to the stroke that the linear drive 2 can perform. This ensures that in the entire linear ⁇ the drive a rotation signal can be obtained area.
