Definitions
- the invention relates to a dry-running rotor compressor with meshing between a screw-toothed rib rotor and a screw-toothed slot rotor with the features of The preamble of claim 1.
- a screw rotor compressor transports as inevitable conveying displacement machine accordingly the medium not only from the suction to the pressure side, but also compresses it this way too, by reducing the size of the tooth spaces. If the rotors or rotors rotate in the housing, they arrive the suction-side control edge out of engagement, so that a Cross section and a volume for suction opens. With another The rotors at their control edges turn again Intervention. The cross section of the axial direction itself moving workspace is reduced to the control edge on the pressure side of the housing on which the compressed medium is pushed out.
- Screw rotor compressors can be used directly with the Engine speed via a built-in or external gear drive.
- Screw rotor compressors with small compression ratios (Final pressure / suction pressure) at which the pumped medium is not included a coolant may be contaminated as dry-running screw rotor compressors or as dry rotors designated and need to maintain the distance of A differential gear, which the rotors in front Touch protects.
- the rotors of these screw rotor compressors have both sides arranged pegs in axial and radial bearings in the housing are stored.
- a screw compressor is known from EP-A-0 101 345, at which the pressure-side ends of the rotors with an inner bearing are provided, while the suction-side rotor ends outside are stored, and the drive point outside the compressor lies.
- the well-known screw compressor shows only in Area of the bearing of the rotors individual sealing sections Atmosphere side. These seals are located radially on the rotors on, which increases the bearing distances.
- the known Screw compressor has a relatively large length on and its sealing is unsatisfactory.
- the drive of the screw rotor compressor can be done on one the rotor ends on the suction or pressure side.
- a torsion shaft is also possible, which is through a hole in the suction or pressure side bearing housing and in one of the four Cone is guided. Via a coupling at the outer end of the Torsion shaft drives the compressor.
- the sealing washers consist of a sintered PTFE-mica mixture or of a material with similar properties.
- the invention has for its object a dry-running screw rotor compressor with extremely short To create design and the shortest possible design to achieve the greatest possible tightness.
- the screw rotor compressor internal rotor bearings are part of the suction side and of the pressure side bearing housing and consist of the same Material, e.g. B. Cast steel.
- the pins protrude into the holes Rotors into it, which are used to support the rotors with sliding or Rolling bearings are equipped.
- the drive of the screw rotor compressor can be on one of the rotor ends on the suction or pressure side. Between the pressure side ends of the rotors and the pressure side Bearing housings are each gear wheels Differential gear and a seal housing with Sealing washers and seals arranged. Between suction-side ends of the rotors and the suction-side Bearing housings are only seal housings, sealing washers and seals provided.
- Sealing the compression space from the environment is achieved with seals that are on the pressure side in one Seal housing and suction side also in one Seal housing that in the suction side bearing housing is attached, attached and against the rotor end faces are directed.
- Gas-sealed seals for example, can be used as seals are used, the particularly high sealing requirements fulfill.
- sealing washers which are also on the seal housing are attached, the tooth gap spaces sealed against each other.
- the gap between the Rotors and the sealing washers will be on during assembly 0 mm set.
- the Sealing discs removed from the rotors as far as for the non-contact run between the sealing washer and rotor is required.
- Dry-running screw rotor compressors resulting from the given pressure level and the specified speed, according to the calculated Bearing force and the required service life, with sliding or roller bearings.
- gear wheels arranged on the pressure side, Seals and the bearing housing are the pressure conditions customized.
- 1 is the suction-side bearing housing (3) on its inside with a pin (25) for Intervention in the bore in the fin rotor (1) and with a further pin (25) for engagement in the Grooved rotor (2).
- the pressure-side bearing housing (5) has on it Also inside the pin (25). One of those cones engages in the hole in the rib rotor (1) and the other into the hole in the slot rotor (2). Both bearing housings (3, 5) are detachable on the compressor housing (4) attached.
- the rotors (1, 2) exist within the Compressor housing (4) only from the screw-toothed Part of the rib rotor (1) and the screw-toothed Part of the slot rotor (2), in the end centric holes for receiving the pin (25) introduced are.
- Fig. 1 is the Drive of the compressor on the pressure side on the rib rotor (1).
- the bearings of the rotors (1, 2) on the pressure side Pin (25) is carried out by radial bearings and axial bearings (20, 22) held by spacer rings (21) and are secured by shaft nuts (23). Suction side are the rotors (1, 2) in radial bearings (12) on the Pin (25) stored.
- the rib rotor (1) is driven on the pressure side with the help of a torsion shaft (9) with coupling flange.
- This torsion shaft is through a hole in the pressure-side bearing housing (5) and the pin (25) led and has a thickening at the inside end (26), which is in a recess of the bore of the Rib rotor (1) is located. Between the torsion shaft (9) and the rib rotor (1) is thereby a positive Connected.
- the seal between the spaces between the teeth Rotors (1, 2) are made using sealing disks (15, 16), the in the suction side seal housing (14) or in the pressure side seal housing (8) inserted and be attached.
- This differential consists of a gear wheel (6) for the rib rotor (1) and a gear wheel (7) for the slot rotor (2) with the required pressure side bearing locks (19).
- Fig. 2 shows the design of a screw rotor compressor with radial bearings (12) and (20) for one high bearing load is laid out.
- this is pressure-side bearing housing (5) designed so that wider gear wheels (6 ') on the rib rotor (1) and also wider gear wheels (7 ') on the slot rotor (23) and larger radial and axial bearings (20, 22) be used.
- the gear wheels (6 ', 7') are with spur tooth clutches (24, 27) via central screws (18) with the Rotors (1, 2) connected.
