【発明の詳細な説明】
本発明は、一方のレース、他方のレース、転動
体及び保持器からなる転がり軸受に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rolling bearing comprising one race, another race, rolling elements, and a cage.
殊に、回転トルクの調節を可能とした転がり軸
受に関するものである。 In particular, it relates to a rolling bearing that allows adjustment of rotational torque.
ある種の装置の軸受は回転動力を断つたとき
に、即座に回転が休止することが望ましいものが
ある。 It is desirable for bearings in certain types of devices to immediately stop rotating when rotational power is cut off.
それは回転座上に載置される装置が必要な位置
（回転角度）に止まることによつて、その装置の
機能が目的対象に対し発揮される必要からであ
る。 This is because the function of the device placed on the rotary seat must be exerted on the target object by stopping at the required position (rotation angle).
一般に転がり軸受の摩擦係数は極めて小さく、
回転動力を断つても回転物の慣性で引き続き回転
し、即座には停止しない。 Generally, the friction coefficient of rolling bearings is extremely small.
Even if the rotational power is cut off, it will continue to rotate due to the inertia of the rotating object and will not stop immediately.
そこで、回転停止させたい場合には、軸受外部
にブレーキ装置を取り付けている。 Therefore, if it is desired to stop the rotation, a brake device is attached to the outside of the bearing.
一方、軸受自身で回転トルクを高め、早く停止
する方法もある。 On the other hand, there is also a method of increasing the rotational torque of the bearing itself and stopping it quickly.
例えば、一方のレースに固定した部材を他方の
レースに摺動させてトルクを高めるとか、あるい
は、実公昭55−23066号公報に開示されている如
く、各レースと保持器の間に波形リング状のばね
を介在させて、両レース間の摩擦を高くする方法
もある。 For example, a member fixed to one race may be slid onto the other race to increase torque, or a corrugated ring may be formed between each race and the retainer as disclosed in Japanese Utility Model Publication No. 55-23066. Another method is to use a spring to increase the friction between the two races.
しかし、これ等従来のものにあつては通常の軸
受部品以外に更にトルクを高める必要な部材を軸
受外にあるいは軸受内に装着する必要がある。 However, in these conventional bearings, in addition to normal bearing parts, it is necessary to install members necessary to further increase the torque outside or inside the bearing.
また、それらは所望トルクを得るための調節が
容易でない。 Also, they are not easy to adjust to obtain the desired torque.
その他、軸受すきまを予圧すきまとし、転動体
と軌道との面圧を高めてトルクを大きくする方法
も講ずることができるが、この場合、一方のレー
スを軸方向に直角な面で分割した形にして予圧を
得るとか、組合わせ軸受にするとかの必要があ
り、更に回転トルクとしては軌道面の形状誤差に
伴なう変動があり、前記の装置に用いるものとし
ては好ましいものでない。 Alternatively, it is possible to use a preload clearance in the bearing to increase the contact pressure between the rolling elements and the raceway to increase the torque. It is necessary to obtain a preload or use a combination bearing, and furthermore, the rotational torque fluctuates due to errors in the shape of the raceway surface, so it is not preferable for use in the above-mentioned device.
本発明の目的は、従来の前記欠点を解決した、
すなわち、軸受部品の点数を増加せず、かつ、回
転トルクを容易に調節とした転がり軸受を提供す
ることを課題にしたものである。 The object of the present invention is to solve the above-mentioned drawbacks of the conventional technology.
That is, it is an object of the present invention to provide a rolling bearing in which the number of bearing parts is not increased and the rotational torque can be easily adjusted.

に接触する。 The segment type retainer 43 has a curvature R of its outer diameter.
1 is larger than the curvature R10 of the inner diameter surface 12 of the race 10, and the curvature R2 of the inner diameter is greater than the curvature R2 of the inner diameter surface 12 of the race 20.
is larger than the curvature R20 of the outer diameter 23 of the segment type retainer 43, and as a result, both ends 431 of the segment type retainer 43 in the circumferential direction are attached to the inner diameter surface 12 of the race 10, and the center portion 43

An outer protrusion 453 protrudes radially outward at the center portion 452 and an inner protrusion 45 protrudes radially inward at the central portion 452.
4, the outer protrusion 453 is in elastic contact with the inner diameter surface 12 of the race 10, and the inner protrusion 454 is in elastic contact with the outer diameter surface 23 of the race 20.
本発明の転がり軸受は上述の如き構成となつて

て極めて簡単に実施できる。 The required torque differs depending on the load applied to the bearing, etc., but in any case, in order to obtain the desired rotational torque, segment type cages 43, 44, 45 are used.
This can be carried out very easily by appropriately changing the number of the projections to be incorporated, or by slightly changing the curvature or the amount of protrusion of the projections.
また、実施例ではセグメント形保持器を合成樹
脂としているので弾性的に摩擦接触しているが接
触面にカジリが生ずることはない。 Further, in the embodiment, since the segment type retainer is made of synthetic resin, there is elastic frictional contact, but no galling occurs on the contact surface.
