【発明の詳細な説明】
本発明はりニアモータに関し、特に出力軸ノ回転規制に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a beam near motor, and particularly to regulating the rotation of an output shaft.
リニアモータは出力軸に直線運動を得るものであるが、
この出力軸は回転自由であり、回転規制を行なう場合、
従来は外部に回転規制装置をつけなげればならない欠点
があった。A linear motor obtains linear motion on its output shaft, but
This output shaft is free to rotate, and when regulating rotation,
Conventionally, there was a drawback that an external rotation regulating device had to be attached.
本発明は上記した従来の欠点を一掃するだめのもので、
リニアモータ外部になんら回転規制装置を設げる必要の
ない構造のりニアモータを提供するものである。The present invention is intended to eliminate the above-mentioned conventional drawbacks,
To provide a linear motor with a structure that does not require any rotation regulating device provided outside the linear motor.
以下、その一実施例について図面に従って説明する。An embodiment thereof will be described below with reference to the drawings.

ヨーク１にボルト７で固定されている。The eccentric rod 5 is press-fitted into the moving coil 4 at a position eccentric from its axis, the center pole 3 and the permanent magnet 2, the permanent magnet 2 and the yoke 1 are fixed with adhesive, and the eccentric rod guide 6 is fixed to the yoke 1 with bolts 7. is fixed.
可動コイル４はセンタポール外周面に設けられた空気軸

。The moving coil 4 is guided by an air bearing 8 provided on the outer peripheral surface of the center pole, and the eccentric rod 5 is slidably guided by an air bearing 9 provided on the eccentric rod guide 6.

山分軸５の回転規制を行なうことができる。The eccentricity of the moving coil 4 and the eccentric rod 5 is the center pole 3.
is equal to the amount of eccentricity between the eccentric rod guide hole 10 in the eccentric rod h valley 6, and in the figure, the output shaft 5 is aligned with its center line AA'
It is free to rotate around the center line B of the moving coil 4.
- It is free to rotate around B', but when the output shaft 5 and moving coil 4 are connected by press-fitting etc., this combined body has two rotation center axes A-A' and B-B'. In the figure, there is a degree of freedom in the direction of the arrow X, but the center line A-A'
Regarding rotation around , since the moving coil 4 is guided around the center line B-B' which is eccentric from A-A',
The rotation of the mountain shaft 5 can be regulated without requiring any device outside the linear motor.

されていない可動コイルを正確に案内しうる。Further, the moving coil 4 may be supported on the center pole 3 via a known sliding bearing, but if it is guided by an air bearing together with the eccentric rod 5 as in this embodiment, the rigidity is higher than that of conventional rolling or sliding bearings. , it is possible to accurately guide a moving coil that has not been accurately guided in the past.
本発明は上記したように、リニアモータの部品点数を増
