矯正機１０を使用するときに、駆動モータ３１の回動によって、減速機３４と、第１ユニバーサルジョイント３５と、第１駆動軸３２の回動によって、第１ロール３３を連動すると共に、駆動モータ３１がプーリ組、第１中間軸３６と、伝動軸５０と、第２中間軸４５と、もう一つのプーリ組と、調節式減速機４３と、第２ユニバーサルジョイント４４と、第２駆動軸４１を回動して、第２ロール４２を連動させ、使用者が調節式減速機４３を第１ロール３３と、第２ロール４２の回転速度比が所定の範囲に調節することができる。矯正機１０が前述構造の適用により、駆動モータ３１のみで第１駆動軸３２と、第２駆動軸４１の回動を駆動し、第１駆動軸３２と、第２駆動軸４１が簡単な構造をもって、互いに伝動して所定の回転速度比に達成することができる。   When the correction machine 10 is used, the rotation of the drive motor 31 causes the reduction gear 34, the first universal joint 35, and the rotation of the first drive shaft 32 to interlock with the first roll 33, and the drive motor 31 is a pulley set, a first intermediate shaft 36, a transmission shaft 50, a second intermediate shaft 45, another pulley set, an adjustable speed reducer 43, a second universal joint 44, and a second drive shaft 41. By rotating the second roll 42, the user can adjust the adjustable speed reducer 43 so that the rotation speed ratio between the first roll 33 and the second roll 42 falls within a predetermined range. By applying the above-described structure to the straightening machine 10, only the drive motor 31 drives the rotation of the first drive shaft 32 and the second drive shaft 41, and the first drive shaft 32 and the second drive shaft 41 have a simple structure. Can be transmitted to each other to achieve a predetermined rotation speed ratio.

さらに、駆動モータ３１は例えば、一般のモータであり、一般モータで前述効果を達成することができる。公知矯正機で使用するモータの馬力は、ややともすれば３０馬力、５０馬力、１００馬力ないし１５０馬力以上かかる一方、前述した市販の直流モータまたはサーボモータが非常に高価であるほか、公知矯正機には２つのモータを使用している。これに対して、本案の矯正機１０を適用すれば、一つの一般モータで十分、駆動モータ３１のコストが非常に安い。市販の直流モータまたはサーボモータに比べて、コストが数十分の一である。駆動モータ３１がメカニズムを介して、第１駆動軸３２と、第２駆動軸４１を連動できる。第１ロール３３と、第２ロール４２が使用者による不適操作や電力の不安定などであっても、回転速度比が所定の範囲を逸脱されない。   Further, the drive motor 31 is, for example, a general motor, and the general motor can achieve the above effects. The horsepower of the motor used in the known straightening machine is 30 horsepower, 50 horsepower, 100 horsepower or more than 150 horsepower or more, while the commercially available DC motor or servomotor described above is very expensive. Uses two motors. On the other hand, if the straightener 10 of the present invention is applied, one general motor is sufficient and the cost of the drive motor 31 is very low. The cost is several tenths of that of a commercially available DC motor or servo motor. The drive motor 31 can interlock the first drive shaft 32 and the second drive shaft 41 through a mechanism. Even if the first roll 33 and the second roll 42 are not properly operated by the user or the power is unstable, the rotation speed ratio does not deviate from the predetermined range.

以上に説明したものは、本案の好ましい実施例であり、本発明実施の範疇に制限を加わるべきではなく、本発明による数値的の変更又は等効果素子の置き換え、若しくは本発明の特許請求範囲による変更又は修整とも本発明の特許範疇に含まれるものである。   What has been described above is a preferred embodiment of the present invention, and should not be limited to the scope of the present invention. Numerical changes according to the present invention or replacement of an equivalent effect element, or claims of the present invention Any changes or modifications are included in the patent scope of the present invention.
