Definitions

  • the present invention relates to a screw compressor according to the preamble of claim 1.
  • Such screw compressors are used in many applications because their construction is robust and the efficiency that can be achieved is high.
  • An electric motor is usually provided as the drive device for the actual compression device, which has, for example, two interlocking compression screws or screw rotors.
  • the motors of the compressors described above which can be designed as semi-hermetic compact screw compressors, for example, are mostly overhung.
  • the compressor rotor, ie a first compressor screw, and the motor rotor, ie the rotor of the electric motor are arranged on a common shaft (drive shaft) which has two radial bearing points.
  • a first radial bearing point is arranged on the compressor-side end of the shaft and a second radial bearing point is located on the shaft section between the compressor rotor and the motor rotor.
  • This means that the drive shaft or the rotor of the motor is only supported on one side of the motor.
  • the disadvantage here is that with increasing compressor size and with increasing Motor speed resonances can occur, which can lead to the starting of the motor rotor on the motor stator.
  • the EP 1 348 077 A1 a compressor is specified which has a third radial bearing in the form of a roller bearing at the motor-side end of the shaft. This means that the compressor motor is supported on both sides by means of roller bearings. Due to the three bearing points, however, the position of the drive shaft is overdetermined, which can only be compensated if the section of the drive shaft located between the first radial bearing and the third radial bearing is designed to compensate for any misalignment occurring between the radial bearings. This is achieved by a flexible section of the drive shaft.
  • Another compressor, which has roller bearings at all three bearing points, is from the WO 2013/126 970 A1 known.
  • the object of the present invention is to specify a compressor which prevents a collision of the rotor and stator of the motor and at the same time can be implemented in a simple and inexpensive manner.
  • a screw compressor for compressing refrigerant which has an electric motor with a rotor and a stator, as well as a drive shaft and a compression device with (at least) one compressor screw or (at least) one screw rotor, the Compressor screw and the rotor of the electric motor are arranged on or on the drive shaft.
  • the drive shaft is rotatably mounted by means of a first, a second and a third radial bearing and the first radial bearing is arranged between the rotor of the electric motor and the compressor screw.
  • the second radial bearing is arranged on a side of the compressor screw opposite the first radial bearing
  • the third radial bearing is arranged on a side of the rotor of the electric motor opposite the first radial bearing.
  • the first radial bearing and the second radial bearing are each designed as a roller bearing
  • the third radial bearing is designed as a plain bearing.
  • the plain bearing is connected to a lubricant feed and a lubricant discharge, the lubricant feed being connected to a first volume to which a first pressure can be applied and / or the lubricant discharge to a second volume to which a second pressure can be applied Connection.
  • the design of the third bearing as a slide bearing ensures a corresponding play at the bearing point itself, so that the position overdetermination of the drive shaft, which is caused by the bearing of the same in three points, can be compensated for without additional flexural elasticity of the drive shaft or other compensatory measures , while the two roller bearings ensure that the drive shaft is precisely positioned.
  • Fig. 1 is a possible embodiment of a compressor according to the invention, more precisely a screw compressor 10 according to the invention, which is also briefly below is referred to as compressor 10 is shown.
  • the compressor 10 has a housing 12 and an electric motor 14 arranged in the housing 12.
  • the electric motor 14 has a rotor 16 and a stator 18.
  • the screw compressor 10 has a drive shaft 20 and a compression device 22 with a first and a second intermeshing compressor screw or a first and a second intermeshing screw rotor 24 and 26, the first compressor screw 24 and the rotor 16 of the electric motor 14 on or on the Drive shaft 20 are arranged.
  • the drive shaft 20 is accordingly driven in rotation by the electric motor 14 and at the same time drives the compression device 22.
  • the compressor according to the invention can have only one compressor screw 24 or else three or more than three compressor screws.
  • the drive shaft 20 is rotatably mounted in the compressor 10 by means of a first, a second and a third radial bearing 27, 28 and 30, the first radial bearing 27 being arranged between the rotor 16 of the electric motor 12 and the first compressor screw 24.
  • the second radial bearing 28 is arranged on a side of the first compressor screw 24 opposite the first radial bearing 27, and the third radial bearing 30 is arranged on a side of the rotor 16 of the electric motor 12 opposite the first radial bearing 27.
  • the first and second radial bearings 27, 28 are designed as roller bearings
  • the third radial bearing 30 is designed as a plain bearing (here as a plain bearing with fluid friction or hydrodynamic plain bearing, but in alternative embodiments also as a dry running plain bearing).
  • a hydrodynamic slide bearing is also suitable for damping shaft movements and thus also and in particular for damping vibrations.
  • the third radial bearing 30, which is also referred to below as a sliding bearing 30, is connected to a lubricant feed 32 in the form of an oil feed channel and a lubricant discharge 34 in the form of an oil return channel.
  • the lubricant feed 32 is also connected to a first volume (oil distribution space, not shown in the figures), which can be acted upon by a first pressure, in the possible embodiment described here with a compression end pressure of the compressor.
  • the lubricant discharge 34 is also connected to a second volume (not shown in the figures), which can be acted upon by a second pressure, in the possible embodiment described here, approximately a suction pressure of the compressor 10.
  • the second volume is a closed compression work space of the compressor 10, i.e. the work space of the compressor 10, where the suction process has already ended and the compression process has just started. In this working space, the pressure is almost the same as the suction pressure.
  • This construction ensures a supply of lubricant under relatively high pressure, so that the bearing can take place as well as possible and without friction, ie with a lubricant film that is as closed as possible between the plain bearing 30 and the drive shaft 20.
  • the application of a relatively low pressure to the lubricant discharge 34 ensures a reliable discharge of the lubricant which, in the embodiment described here, is formed by the oil which the compressor 10 also uses as a lubricant.
  • the slide bearing 30 is arranged in a bearing receiving bush 36 which is at least partially arranged in the housing 12.
  • the bearing receiving bush 36 is arranged parallel and concentrically to the drive shaft 20.
  • the bearing receiving bushing 36 has a first end 38 through which the drive shaft 20 extends, and a second end 40 which is opposite the first end 38.
  • the bearing receiving bush 36 is sealed at both its first and its second end 38, 40 from the environment, ie the interior of the housing 12, the seal at the first end 38 through which the drive shaft 20 extends by means of a first Cover 42, which has a drive shaft passage 44 and a radial shaft seal 46, takes place.
  • a second cover 48 is arranged for sealing, which is attached to the second end 40 using suitable sealing materials, if necessary.
  • the second end can also be designed, for example, closed, i.e. the bearing receiving bushing 36 can alternatively be designed, for example, in the form of a blind hole or a cylinder closed on one side.
  • the sliding bearing 30 is arranged in a sealed manner from the environment, which means that no lubricant can escape to the environment.
  • the compressor 10 has a lubricant collecting space 50, which is arranged within the bearing receiving bush 36 in the embodiment described here and is connected to the lubricant discharge 34, for collecting and deliberately discharging the sliding bearing lubricant.
  • the lubricant collecting space is in fluid connection with the sliding bearing 30 or is open towards the sliding bearing 30 in order to be able to receive the lubricant of the sliding bearing 30 unhindered, while it is sealed against the environment in a similar way to the sliding bearing 30.
  • the seal against the environment takes place, as also for the slide bearing 30, by the first cover 42 including the radial shaft seal 46 and the second cover 48 limited, which are arranged at the radial ends of the bearing receiving sleeve 36.
  • the lubricant chamber 50 can also be arranged outside the bearing receiving bushing 36 and with the sliding bearing 30, for example be connected via a channel.
  • the lubricant can also be collected in a targeted manner through an additional formation of a lubricant collecting space 50 which is in connection with the sliding bearing (fluid connection, fluid communication).
  • a lubricant collecting space 50 which is in connection with the sliding bearing (fluid connection, fluid communication).
  • the fact that the sliding bearing 30 and the lubricant collecting chamber 50 are arranged sealed against the environment and the targeted removal of the lubricant means that there is no bearing-related lubricant entry into the suction gas flow of the compressor 10.
  • the pressurized lubricant supply leads to the best possible lubricating effect and thus to a further reduced heat development.
