Definitions
- the subject invention relates to a dental work unit with a plurality of devices, such as a suction air generator, a compressed air generator, an amalgam separator and / or a feed pump.
- a suction air generator such as a suction air generator, a compressed air generator, an amalgam separator and / or a feed pump.
- a mobile dental unit is known from US Pat. No. 3,404,458, in which an electric motor fed by an accumulator drives either a suction pump or a compressor.
- a dental unit is also known from EP-A 224 233, in which an electric motor for the common drive of a suction pump and an amalgam separating centrifuge, which are permanently coupled via a transmission, is provided. Since these two devices are arranged side by side, a very low overall height, which is required in some installation situations, is achieved.
- a supply unit for dental workplaces which has a pump operated by a first motor for generating suction air and further a compressor driven by a second motor for generating compressed air, and optionally an air drying unit and a compressed air reservoir which are arranged one above the other arranged individual elements are housed contains.
- a mobile dental care or dental treatment device which has a compressed air generator, a suction unit, a settling vessel and a water reservoir and which is connected to an external power supply and a sewer.
- the object of the present invention is to provide a dental work unit which has a simplified structure compared to the known work units. This is achieved according to the invention in that the devices are assigned a common drive, an individually switchable clutch being provided between the drive and each of the devices. Individual devices of the same type can be provided in any number.
- Such a unit of work is particularly advantageous because only a single drive needs to be provided. Since an individually switchable coupling is provided between each of the devices and the drive, these devices can be switched on and off as required.
- Such a dental work unit preferably contains a suction air generator, a compressed air generator and an amalgam separator working with centrifugal forces, to which devices a common drive is assigned, an individually switchable coupling being arranged between the drive and each of the devices.
- a work unit is thus created which not only contains a single drive element, in particular an electric motor, but which therefore brings about a number of advantages, since the individual devices are easily interchangeable, the entire unit requires little space and the work unit can be converted in a simple manner and can be retrofitted.
- Such a work unit is therefore also particularly suitable as a centrally arranged work unit for several treatment chairs.
- the coupling of the output shaft of the motor with the drive shafts of the devices can be done via spur gears or the like. respectively.
- a self-contained traction means is provided, which is guided over a transmission disk arranged on the output shaft of the motor and over clutch disks which are assigned to each drive shaft of the devices.
- V-belts, multiple V-belts, toothed belts or the like are used as traction means. usable.
- an electromagnetic clutch is assigned to each device drive shaft for the optional coupling to the drive motor.
- a first clutch plate is rotatably mounted on the respective drive shaft for the devices and a second clutch plate is non-rotatable and axial Slidably arranged, which can be pressed by means of the electromagnet to the first clutch disc driven by the traction means.
- a braking element can also be provided, against which the second clutch disc, which is under the action of a return spring, can be pressed.
- the second clutch disk is preferably provided on both sides with a clutch or brake lining.
- a common support plate is provided, on which the drive motor is arranged in a central position and the devices in a peripheral position. This enables a small space requirement.
- the object of the invention is based on one in the
- FIG. 1 shows a working unit according to the invention with three devices, in a schematic representation and in a side view
- FIG. 2 shows the working unit according to FIG. 1, in a top view
- FIG. 3 shows the coupling of one of the devices of this working unit, in an axial direction
- a dental work unit contains a drive motor 1 and at least three devices which can be coupled to the drive motor 1, namely a suction air generator 2, in particular for the extraction of liquid and solids from the patient's mouth, a compressed air generator 3 for dental treatment and an amalgam separator 4, in which the extracted solids are separated from the liquid by centrifugal forces.
- a centrifuge or another centrifugal device, for example a cyclone, can be provided for this.
- Each of the devices 2, 3 and 4 has a drive shaft 8 on which a clutch disc 5 is rotatably mounted.
- the drive shafts 8 of the devices 2, 3 and 4 are aligned parallel to the output shaft of the motor 1, on which a transmission disk 15 is provided. Furthermore, the drive shafts 8 of the devices 2, 3 and 4 couplings 7 are assigned.
- the drive motor 1 is arranged in a central position on a square support plate 9, being surrounded by the devices 2, 3 and 4, which are arranged in three corner regions of the support plate 9.
- the transmission disk 15 of the motor 1 and the clutch disks 5 of the three devices 2, 3 and 4 as well as a second, empty transmission disk 15, which is rotatably mounted in the fourth corner region of the support plate 9, are wrapped by an endless traction means 6, for example a multiple V-belt.
- Known tensioning rollers 25 are also provided.
- a second clutch disc 11 is arranged on the free end of each drive shaft 8 of the devices 2, 3 and 4 in a manner fixed against relative rotation and axially displaceable relative to the action of a return spring 13. Furthermore, annular electromagnets 10 are arranged on the support plate 9, which surround the drive shafts 8 and which engage in an annular groove of the first clutch disc 5.
- the assigned second clutch disc 11 is attracted, whereby it is pressed against the action of a return spring 13 against the first clutch disc 5, whereby the device 2, 3 and 4 in question is coupled to the drive motor 1 for entrainment.
- the electromagnet 10 is de-energized, the second clutch disc 11 is returned to its rest position shown in FIG. 3 by the return spring 13, as a result of which this device is switched off again by the drive 1. So that the devices 2, 3 and 4 can be braked quickly, a brake plate 12 is fastened on the support plate 9, against which the clutch disc 11 is pressed by the return spring 13.
- another device can be provided.
- such a work unit can have any number of different devices to which a single drive unit is assigned. In particular, such a work unit can have several devices of the same type, that is to say, for example, a plurality of suction air generators and the like.
