この発明は、転勤体を保持案内する保持器が外輪または
内輪のいずれか一方の軌道論によって案内される軌道輪
案内形式の保持器を有し、かつ、軸受が油（ｏｉｌ）、

改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a cage for holding and guiding a rolling body, which has a bearing ring guided type cage guided by the raceway theory of either the outer ring or the inner ring, and the bearing is oil-free. (oil),
This invention relates to rolling bearings such as ball bearings and roller bearings that are lubricated with grease or the like, and particularly to improvements in the guide type of cages.
一般にこの種の軌道論案内形式の保持器を有する転がり
軸受における保持器は、正常時には、その回転周期でわ
ずかに振れまわりながら回転している。Generally, in a rolling bearing having this kind of orbital guide type cage, the cage rotates while swinging around slightly in its rotation period during normal operation.
そして、この振れまわり量が４・さくて安定していると
き保持器は安定状態にあるという。ところが、なんらか
の原因で保持器の振れ量が急激に大きくなり、時として
保持器の案内すきま（保持器の案内部の周面とこれと対

わることがあり、（不安定現象が生じ）保持器が不安定
状態におち入ることがある。このような保持器の不安定
現象は、軸受がハウジングに直接支持されている剛体支
持の場合（第１図参照）にあっても、あるいはダンパ一
等を介０して間接支持されるダンパ−支持の場合（第２
図参照）にあっても発生する。The cage is said to be in a stable state when this amount of whirl is stable at 4. However, for some reason, the amount of cage deflection suddenly increases, and sometimes the guide clearance of the cage (the gap between the circumferential surface of the guide part of the cage and the opposing circumferential surface of the orbital theory) becomes full. It may swing around (an instability phenomenon occurs) and the cage may fall into an unstable state. This instability of the cage can occur even when the bearing is rigidly supported directly on the housing (see Figure 1), or when the bearing is supported indirectly through a damper etc. In case of support (second
(see figure).
保持器の不安定現象は軸受が剛体支持されている場合に
は、主として保持器の不つり合いによって発生する。When the bearing is rigidly supported, cage instability occurs mainly due to cage imbalance.
そして、保持器の不つり合いが大き夕いほどその振れま
わりが大きい。また軸受がダンパー支持されている場合
は、軸受が動きやすくなっているので、軸系の振動が、
その共振点を通過するとき大きくなり、このため外輪が
大きく振れまわり保持器は案内すきまいつ０【まし、に
振れまわる。The greater the cage imbalance, the greater the swing. In addition, if the bearing is supported by a damper, the bearing can move easily, so vibrations in the shaft system can be reduced.
When it passes through that resonance point, it becomes larger, and as a result, the outer ring swings around a lot, and the cage swings around with a guide clearance of 0.
軸受の回転中、保持器に上記のような振れまわりによる
不安定現象が生じると、互の接触面聞く案内面間）の潤
滑油膜が破断し、前記接触面が摩耗したり、燐付いたり
、更には保持器が破断さ夕れるという重大な危険がある
。If the above-mentioned unstable phenomenon occurs in the cage due to whirling while the bearing is rotating, the lubricating oil film between the mutual contact surfaces (between the guide surfaces) will break, and the contact surfaces will wear out, become phosphorous, etc. Furthermore, there is a serious risk that the cage will break and collapse.
特にダンパー支持された軸受にあっては、外輪の振れま
わりにより外輪からの励振力が大きくなるとともに案内

つたとき前述の油膜が破断しやすいという欠点があった
。Particularly in damper-supported bearings, the excitation force from the outer ring increases due to swinging of the outer ring, and the formation of an oil film on the guide surface deteriorates, significantly reducing the ability to attenuate the excitation force. Larger than support.
As a means to solve such problems, for example, as disclosed in Jikoko No. 18521/1987, a pad is provided that is pivotally supported on the outer ring, and the support surface of the pad and the curved surface of the cage are A structure in which the retainer is guided through an oil film formed between the retainer and Therefore, there was a drawback that the oil film described above was easily broken when an impact force was applied.

止するようにしたものである。The purpose of this invention is to prevent the occurrence of instability in the retainer of the subordinate bearing. Specifically, the purpose of this invention is to prevent the retainer from being unstable by mechanical spring force and the viscosity of a viscous fluid layer. It is supported by a damper and attenuates the unbalance of the cage and the excitation force coming from the ball or outer ring, thereby suppressing the vibration of the cage to a smaller extent and also preventing the breakage of the oil film as in the above-mentioned conventional method. be.

In the figure, reference numeral 8 denotes a retaining ring that engages with the retaining tongues 502, 502, . . . of the cylindrical body to prevent the cylindrical body 501 from falling off. 5 As mentioned above, in the rolling bearing of the present invention, the cage in particular has the following features:
Since the structure is supported by a damper through the elasticity of the cage guide member having spring properties and the viscous fluid film, it is possible to buffer the vibrations of the cage and suppress its whirling to a small extent. breakage can also be effectively prevented. Therefore, there is no wear or seizure of the contact surfaces due to lack of lubrication as in the conventional case, and the risk of damage to the cage is reliably prevented. In the embodiments, a ball bearing in which the cage is guided by an outer ring is described, but it may be guided by an inner ring, and the bearing is not limited to a ball bearing.
