この考案は、車両のプロペラシャフト等のドライブシャフトのユニバ−サルジ ョイント、特に十字軸端部内に存在するグリ−スの劣化或いはグリ−ス自体の過 不足を簡単に調べることの出来るユニバ−サルジョイントに関する。 This invention is a universal joint that can easily check the deterioration of the grease present in the end of the cross shaft or the excess or deficiency of the grease itself, especially the universal joint of the drive shaft such as the propeller shaft of the vehicle. Regarding

プロペラシャフト等に用いられるドライブシャフトは途中でユニバ−サルジョ イントで連結される。このユニバ−サルジョイントの十字形軸（スパイダ）内部 には各軸の先端部まで十字形状の潤滑剤充填用通路が設けられ各軸の先端部に装 着した軸受部を潤滑剤（グリ−ス）で潤滑するようになっている。前記軸受部は 通常ロ−ラとベアリングカップとより構成され駆動軸と被駆動軸のヨ−ク部に嵌 め込まれるが回転駆動時には比較的高温となり、グリ−スの粘度が変化したり漏 洩したり通路途中で固まったりしやすくなる。従って、ユニバ−サルジョイント 用の潤滑剤（グリ−ス）は温度の変化と共に粘度も変化するので劣化度合や充填 量等充分注意を払う必要がある。従来のユニバ−サルジョイントには十字形軸内 部の通路内部のグリ−スを攪拌するものとして十字形軸先端部の潤滑通路に攪拌 具（ボ−ル）を配置したユニバ−サルジョイント（特開昭５６−９７６２８号） や、グリ−スの漏洩を防止するため十字軸先端部の軸と軸受外輪（ベアリングカ ップ）との間に密封物を挿入すると共に該密封物に接触する突起を軸側又は軸受 外輪側に固定したユニバ−サルジョイント（実開昭５３−１４９１５８号）が知 られている。 The drive shaft used for the propeller shaft and the like is connected with a universal joint on the way. Inside the universal joint's cross-shaped shaft (spider), a cross-shaped lubricant filling passage is provided up to the tip of each shaft, and the bearings attached to the tip of each shaft are lubricated (grease). ) To lubricate. The bearing is usually composed of a roller and a bearing cup and is fitted into the yokes of the drive shaft and the driven shaft. However, the temperature of the bearing becomes relatively high during rotational driving, and the viscosity of the grease changes or leakage occurs. It is easy to leak or harden in the middle of the passage. Therefore, since the viscosity of the universal joint lubricant (grease) changes with temperature, it is necessary to pay sufficient attention to the degree of deterioration and filling amount. The conventional universal joint has a universal joint (special feature) in which a stirrer (ball) is arranged in the lubrication passage at the tip of the cross-shaped shaft to stir the grease inside the passage inside the cross-shaped shaft. No. 56-97628), or a protrusion that inserts a sealant between the shaft at the tip of the cross shaft and the bearing outer ring (bearing cup) and prevents the grease from leaking. A universal joint (No. Shokai 53-149158) in which a shaft is fixed to the shaft side or the bearing outer ring side is known.

ユニバ−サルジョイントの十字形軸内部に封入された潤滑剤（グリ−ス）の劣 化度合いや不足状況を知るためには組み込まれている機械からユニバ−サルジョ イントを取外して分解しなければ分からない。従って潤滑剤（グリ−ス）の追加 や交換状況を判断するだけのために稼働を停止させ分解するのは大掛かりとなり 極めて非能率的である。 In order to know the degree of deterioration or lack of lubricant enclosed in the cruciform shaft of the universal joint, it is necessary to remove the universal joint from the built-in machine and disassemble it. Absent. Therefore, it is very inefficient to stop the operation and disassemble it just to judge the addition or replacement status of the lubricant (grease).
【０００４】 この考案は上記課題に鑑みてなされたものであり、その目的とする所はユニバ −サルジョイントを取外すことなく停止させるだけで潤滑剤（グリ−ス）の劣化 度合いや過不足状況を調査することの出来るユニバ−サルジョイントを提供する ことにある。The present invention has been made in view of the above problems, and its purpose is to stop the deterioration of the lubricant (grease) and the excess or deficiency of the lubricant simply by stopping the universal joint without removing it. It is to provide a universal joint that can be investigated.

即ち、この考案は上記する課題を解決するために、十字形軸の各軸先端部にロ −ラとベアリングカップとより成る軸受を設けると共に該十字形軸内部より各軸 受方向に十字形状の潤滑剤用通路を設けたユニバ−サルジョイントにおいて、前 記十字形軸の各軸先端部軸受のベアリングカップに細長い棒状部を有するゲ−ジ を取付けたことを特徴とする。 That is, in order to solve the above-mentioned problems, the present invention provides a bearing consisting of a roller and a bearing cup at the tip of each cross-shaped shaft and forms a cross-shaped shape from inside the cross-shaped shaft in each bearing direction. A universal joint provided with a lubricant passage is characterized in that a gauge having an elongated rod-like portion is attached to a bearing cup of each shaft end bearing of the cross-shaped shaft.

この考案のユニバ−サルジョイントを上記手段とすると、必要な時機械を停止 させるだけでゲ−ジをベアリングカップから外し、該ゲ−ジの細長い棒状部に付 着した潤滑剤を調査して潤滑剤の劣化度合を判断することが出来る。また、ゲ− ジの細長い棒状部のどのあたりまで潤滑剤が付着しているかを調べると潤滑剤の 過不足状況を判断することが出来る。従って潤滑剤の追加、交換を判断すること が容易となり、潤滑上の管理を行う上で極めて有効となる。 When the universal joint of the present invention is used as the above means, the gauge is removed from the bearing cup simply by stopping the machine when necessary, and the lubricant attached to the elongated bar portion of the gauge is investigated and lubricated. It is possible to judge the degree of deterioration of the agent. In addition, it is possible to determine the excess / deficiency of the lubricant by examining the extent to which the lubricant adheres to the elongated bar portion of the gauge. Therefore, it becomes easy to judge the addition or replacement of lubricant, which is extremely effective in managing lubrication.

以下、この考案の具体的実施例について図面を参照して説明する。 図１（Ａ）はこの考案のユニバ−サルジョイトの一部断面正面図である。この ユニバ−サルジョイントの十字形軸１内部には十字形状に潤滑剤通路１１が軸先 端部１ａまで貫いて設けられている。そして該十字形軸１の側面にはグリ−スニ ップル取付用の雌ねじ１ｂが設けられ該雌ねじ１ｂから前記十字形状の通路１１ に連通する通路１２が設けられている。 Hereinafter, a specific embodiment of the present invention will be described with reference to the drawings. FIG. 1 (A) is a partially sectional front view of the universal saljoite of the present invention. A lubricant passage 11 having a cross shape is provided inside the cross-shaped shaft 1 of the universal joint so as to extend to the shaft end 1a. A female screw 1b for attaching a grease snipple is provided on a side surface of the cross-shaped shaft 1, and a passage 12 communicating from the female screw 1b to the cross-shaped passage 11 is provided.
【０００８】 次に、前記十字形軸１の軸先端部１ａにはロ−ラ２１とベアリングカップ２２ とより成る軸受２が装着され且つ該ベアリングカップ２２と軸先端部１ａとの間 はシ−ル３が嵌め込まれる。前記ベアリングカップ２２の中央部には雌ねじ部２ ２ａを設けると共にここにゲ−ジ４を螺合させて取付けてある。該ゲ−ジ４は、 図１（Ｂ）に示すように、前記ベアリングカップ２２の雌ねじ部２２ａに螺合す る雄ねじ部４ａと細長い棒状部４ｂとより成り（尚、雄ねじ部４ａの端部（ヘッ ド）４ｃはスパナ等で回転させやすく六角形としてある）、更に該ゲ−ジ４の細 長い棒状部４ｂの表面はグリ−ス等が付着し易くするためロ−レット加工したり 、細い線状の刻印を設けてある。Next, a bearing 2 composed of a roller 21 and a bearing cup 22 is mounted on the shaft tip portion 1a of the cross-shaped shaft 1, and a seal is provided between the bearing cup 22 and the shaft tip portion 1a. Le 3 is fitted. A female screw portion 22a is provided at the center of the bearing cup 22, and a gauge 4 is screwed into and attached to the female screw portion 22a. As shown in FIG. 1B, the gauge 4 is composed of a male screw portion 4a screwed to the female screw portion 22a of the bearing cup 22 and an elongated rod-shaped portion 4b (note that the end portion of the male screw portion 4a is (Head 4c is a hexagon that can be easily rotated with a wrench, etc.), and the surface of the elongated rod-shaped portion 4b of the gauge 4 is knurled to make it easy for grease to adhere. A fine line-shaped stamp is provided.
【０００９】 上記するようにゲ−ジ４は十字形軸１の軸先端部１ａのベアリングカップ２２ に一個取付けるが、十字軸の書く軸のベアリングカップ２２の全てに取付けても 良いが、一個だけ取付ける場合には他の三箇所にはプラグ（盲栓）５を取付け潤 滑剤の漏洩を防止する。また、ゲ−ジ４の細長い棒状部４ｂの長さは使用目的に 応じて適当な長さとすれば良く十字形軸１の中心近くまでの長さとしても良いし 軸端部１ａの半分或いはそれ以下の長さとしても良い。As described above, one gauge 4 is attached to the bearing cup 22 of the shaft tip portion 1a of the cross shaft 1, but it may be attached to all the bearing cups 22 of the shaft written by the cross shaft, but only one. When installing, attach plugs (blind plugs) 5 to the other three places to prevent lubricant leakage. The length of the elongated rod-shaped portion 4b of the gauge 4 may be set to an appropriate length according to the purpose of use, and may be a length close to the center of the cross-shaped shaft 1 or half of the shaft end 1a or it The following lengths may be used.
【００１０】 この考案のユニバ−サルジョイントを上記構成とすると、必要な時機械を停止 させるだけでゲ−ジ４をベアリングカップ２２から外し、該ゲ−ジ４の細長い棒 状部４ｂに付着した潤滑剤（グリ−ス）を調査して潤滑剤の劣化度合を判断する ことが出来る。また、ゲ−ジ４の細長い棒状部４ｂのどのあたりまで潤滑剤が付 着しているかを調べると潤滑剤の過不足状況を判断することが出来る。従って潤 滑剤の追加、交換を判断することが容易となり、潤滑上の管理を行う上で極めて 有効となる。When the universal joint of the present invention has the above-mentioned structure, the gauge 4 is removed from the bearing cup 22 by simply stopping the machine when necessary, and attached to the elongated rod-shaped portion 4b of the gauge 4. The degree of deterioration of the lubricant can be determined by examining the lubricant (grease). Further, by checking up to which part of the elongated bar portion 4b of the gauge 4 the lubricant has adhered, it is possible to judge whether the lubricant is excessive or insufficient. Therefore, it becomes easy to judge the addition or replacement of lubricant, which is extremely effective in controlling lubrication.
