〔産業上の利用分野〕
本発明はスクリュー圧縮機の駆動装置に係り特に無給油
式スクリュー圧縮機に好適なオスメスロータを非接触に
て駆動する装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drive device for a screw compressor, and particularly to a device for non-contactly driving a male and female rotor suitable for an oil-free screw compressor.
（従来の技術〕
従来の駆動装置は、無給油式スクリュー圧縮機でロータ

いては実開昭５３−５７３０７号に記載のように改善が
はかられタイミングをとる技術となっていた。(Prior art) Conventional drive devices generally use gears to increase the rotation speed of the motor in order to adjust the timing between the rotors in an oil-free screw compressor, and the gear arrangement is not practical. As described in Japanese Patent Application No. 53-57307, improvements were made to the timing technology.
〔発明が解決しようとする１４題）

り、この油がロータへ行かないよう軸封部を設けて圧縮
空気中への混入を防止しているが、軸封部の不良などで

ギヤー固有の振動、騒音が高く、無給油式の欠点となっ
ていた。[14 Problems to be Solved by the Invention] The above conventional technology uses oil to lubricate a part of the gear, and a shaft seal is provided to prevent this oil from going to the rotor and prevent it from entering the compressed air. However, there is a possibility of contamination due to defects in the shaft seal, and since the gear rotates at high speed, the vibration and noise inherent to the gear are high, which is a drawback of the oilless type.
本発明の目的は、ギヤーによる騒音を低減すること、ま

給油式スクリュー圧縮機を提供することにある。An object of the present invention is to provide an oil-free screw compressor that improves product quality by reducing noise caused by gears and preventing lubricant from getting mixed in.

定にでき、非接触にてかみ合って回転することができる
ことで達成される。The above purpose is to eliminate the gear and its lubricating oil piping. Instead of gears, multiple plate-shaped electromagnets with coils wound around the teeth of the gears are attached to the shaft of the rotor, stacked one on top of the other, with the tips of the teeth slightly shifted. Electromagnets of the same size and number are attached to the shaft of each rotor, and the tips of the teeth are arranged so that there is a slight gap between them. Immediately before operation, a voltage is applied to the electromagnet to create an attractive force in the direction where the gap between the tooth tips becomes smaller and a repulsive force in the direction where the gap between the tooth tips becomes larger. This allows for proper starting timing. When the male rotor rotates and operates, the position of the tooth tip changes and the electromagnetic force becomes stronger, which transmits the rotation to the female rotor and causes it to operate in synchronization. This is achieved by allowing the male and female rotors to maintain a constant gap and engage and rotate without contact.
オスメスロータの軸部に設けた電磁石に歯先のギャップ
が小さくなる方向には吸り、［の電圧を加え。Apply a voltage to the electromagnet installed on the shaft of the male/female rotor in the direction that reduces the gap between the tooth tips.
また歯先のギャップが大きくなる方向に反発の電圧を加
えるとロータ間は磁気力で一定のギャップを形成する。Furthermore, when a repulsive voltage is applied in the direction that increases the gap between the tooth tips, a constant gap is formed between the rotors due to magnetic force.

入することもなくなる。Therefore, by controlling the voltage when starting rotation, backlash can be kept constant and collision between the rotors can be prevented. It can also be used as a brake if the voltage is controlled during driving. As a result, the male and female rotors can be operated with a constant gap, allowing the non-contact compressor to be driven.There is no source of noise, there is no lubricating oil system, and there is no oil mixed into the supplied air.
以上本発明の一実施例を第１図により説明する。 An embodiment of the present invention will be described above with reference to FIG.

歯の部分にそれぞれ電磁コイル８が取付けられている。The compressor has a male rotor 1 and a female rotor 2 built into a casing 4 that mesh with each other to compress air. A motor 3 is connected to the male rotor 1. A plurality of plate-shaped electromagnets 5 are attached to the ends of the shafts of the male rotor 1 and the female rotor 2, and the tips of their teeth face each other with a slight gap. The plate-shaped electromagnet 5 has the shape of a gear, and an electromagnetic coil 8 is attached to each tooth portion.

逆回転でメスロータ２が同期し回転する。Voltage is supplied to the coil 8 at each tooth tip from the voltage control device 7 via the slip ring 6, and before operation, the coils 8 at the portions in contact with the male and female rotors attract each other in the direction where the tooth tip gap becomes smaller. , the position is determined by the repulsive force in the direction where the gap is wide (larger).When the operation starts, as the male rotor 1 rotates, the attraction and repulsive force become stronger due to the displacement of the tooth tips of the plate electromagnet 5, and the male rotor 1 rotates in the opposite direction. The female rotor 2 rotates in synchronization.

製品の欠点がなくなり大きな効果が生じる。Figure 2 shows a combination of plate-shaped electromagnets in which a plurality of electrode stones are stacked one on top of the other in a slightly shifted manner to increase magnetic force and reduce rotation errors. According to this embodiment, since gears and lubricating oil piping can be eliminated, the disadvantages of products such as noise, vibration, and oil leakage can be eliminated, resulting in a great effect.

る。According to the present invention, it is possible to eliminate the gears that cause noise and the gear lubricating oil that gets mixed into the compressed air, and to adjust the timing by electrical control. In addition, stable rotation can be obtained by using a combination of plate-shaped electromagnets to counter unbalanced rotation.
