Description
【考案の詳細な説明】 本考案は携帯用電動工具の二段変速装置に関する。[Detailed explanation of the idea] The present invention relates to a two-stage transmission device for a portable power tool.
従来、携帯用電動工具の二段変速装置は多数実施されて
いるが、何れも機構が複雑で大型となるため携帯用電動
工具の操作に支障をきたしたり、又コストが高く、修理
し難かったり、又工具使用中に変速切換え操作がほとん
ど出来ず、ギヤの噛合に細心の注意をしなければならな
い等の難点があった。Conventionally, many two-speed transmission devices for portable power tools have been implemented, but all of them have complex and large mechanisms that hinder the operation of portable power tools, and are also expensive and difficult to repair. In addition, there were other drawbacks, such as the fact that it was almost impossible to change gears while the tool was in use, and great care had to be taken in the meshing of the gears.

ヤ二個の内面に夫々クラッチ歯を設け、クラッチ部材を
切換機構によりスピンドル上を左右に移動し、ファイナ
ルギヤの一方と噛合してスピンドルと連結する変速装置
は公知である。For example, a pair of final gears are rotatably mounted on a spindle at regular intervals, a clutch member is mounted at an intermediate position between the two final gears so as to be slidable in the axial direction and rotate together with the spindle, and then A transmission is known in which clutch teeth are provided on the inner surfaces of two final gears, the clutch member is moved left and right on a spindle by a switching mechanism, and is engaged with one of the final gears to be connected to the spindle.
しかし前記変速装置はクラッチ部材を切換機構により強
制的にファイナルギヤと噛合させるため、工具使用中、
即ちスピンドル回転中に変速切換え操作を行えず、無理
に変速切換え操作を行なえばギヤを欠損させる等の欠点
がある。However, since the transmission device forcibly engages the clutch member with the final gear by a switching mechanism, when using the tool,
That is, it is not possible to perform a gear change operation while the spindle is rotating, and if the gear change operation is performed forcibly, there is a drawback that a gear may be damaged.
又工具を停止した状態で変速切換え操作を行なった場合
も、クラッチ部材とファイナルギヤのクラッチ歯が噛合
しない場合はスピンドルを手動で回転させながら噛合さ
せなければならない等の欠点があった。Further, even when the gear change operation is performed with the tool stopped, there is a drawback that if the clutch member and the clutch teeth of the final gear do not mesh, the spindle must be manually rotated to mesh them.

ルギヤは外方向よりスプリングにより弾性賦勢されてい
るために各部品間に摩擦を生ずる個所が多発する。Also, unlike the configuration of the transmission described above, for example,
- As in the transmission disclosed in No. 107182, a pair of final gears are fitted on a spindle while moving and idling, and clutch teeth are provided facing each other on the inside, and the outer end surfaces of both final gears and the spindle stage are provided with clutch teeth facing each other. A spring is loaded between the two final gears to elastically bias both final gears inward, and a fixed pin is provided on the spindle between the two final gears so as to move together with the spindle. There is also a transmission device in which the gear moves left and right on the spindle so that both latches engage with the fixed pin, but the switching device also
Although the above conventional drawbacks can be eliminated, since the final gear is configured to move, it is necessary to provide a wide tooth width to accommodate the movement of the intermediate gear that meshes with it, and both final gears are elasticized by springs from the outside. Because of the energization, there are many places where friction occurs between each part.
例えば固定ピンと係合していないファイナルギヤではス
ピンドルとの回転数が異なり、スプリングの両端面では
摩擦抵抗を生じることで摩擦抵抗により駆動伝達力は弱
まりパワーロスの発生と部品の摩耗が激しい等の欠点が
あった。For example, in a final gear that is not engaged with a fixed pin, the rotation speed is different from that of the spindle, and frictional resistance is generated on both end faces of the spring, which weakens the drive transmission force, resulting in power loss and severe wear of parts. was there.

衝撃が伝わる事なく円滑に切換操作を行ない得る新規な
二段変速装置を得させたものである。As mentioned above, the present invention uses a two-stage transmission in which the latch plate slides on the spindle and meshes with the final gear, and is connected to the spindle, so that the intermediate gear has the same width as the final gear, and Frictional resistance is also extremely small, and the drawbacks of the conventional types mentioned above have been eliminated. Clutch engagement can be performed reliably even when the tool is rotating or stopped, and the impact when gears engage is eliminated. To provide a new two-stage transmission device that protects the gears by absorbing the noise and allows smooth gear shifting operations without transmitting impact to the hands through the handle.

スピンドルは停止している。The pinion 10 and intermediate gear 7 are driven by the motor shaft.
mesh with each other, the intermediate shaft 5 is rotationally driven, and the other intermediate gears 8. The final gears 11 and 12 that are in mesh with each other rotate on the spindle 6 at a fixed position, but since the clutch plates 16 and 17 do not mesh in the intermediate position between the final gears 11 and 12 shown in the second figure, they are not engaged with the spindle. No join is made 1,
The spindle is stopped.

１２ａは噛合することになる。Next, when the handle 23 of the switching device 21 is rotated, the shifter 25 is moved to the left or right by the eccentric shaft 24. Therefore, by rotating the handle shaft 23, the shifter 25 is moved to the right as shown in the first figure. In this position, the shifter 25 moves the clutch plates 16, 17 through the annular member 19.
moves to the right on the spindle, and one clutch plate 1
The tooth portion 17a of No. 7 meshes with the clutch tooth 12a of one final gear.

ンドル回転中でもクラッチ係合は行なわれる。When the handle is rotated 180 degrees from the above position, the engagement is released and the teeth 16a of the other clutch plate and the clutch teeth 11a of the other final gear 11 are engaged, but the compression spring 18 causes the clutch teeth to engage. The clutch plate, which is elastically repelled in the direction of engagement, moves back against the elastic force of the compression spring in response to the impact caused by the engagement with the clutch teeth, and the impact force is absorbed, so that when the tool is in use, In other words, the clutch is engaged even while the spindle is rotating.
又その時の衝撃はハンドルを通して手に伝達される事も

回転すれば、すぐにクラッチ係合が行なわれる。Also, if you operate the switching device to move the clutch plate as described above when the tool is stopped, and the teeth do not mesh with the clutch teeth, you can set the handle in the specified position and move the clutch plate as described above. Since the final gear is elastically biased in the direction of meshing with the clutch teeth, the clutch is engaged immediately when the final gear rotates by starting the tool.
従ってスピンドルを手で回転させながらクラッチ係合を
行なう必要はなくなる。Therefore, it is no longer necessary to engage the clutch while rotating the spindle by hand.
又二個のクラッチ板１６．１７は環状部材１９が嵌合し

の摩耗もなく耐久性に富むものである。As described above, the two-stage transmission of the present invention has the two clutch plates 16 and 17 placed at intermediate positions between the pair of final gears 11 and 12 which are loosely fitted to the spindle 6 at a constant interval, so that the two clutch plates 16 and 17 can be rotated together with the spindle 6. It is rotatably fitted into an annular member 19 so as to be movable left and right on the shaft and fixed at a constant interval, and a compression spring 18 is interposed between both clutch plates to engage the clutch plate with the clutch teeth of the final gear. Since the annular member 19 is made to bounce in the direction of
The compression spring 18 deforms and absorbs the impact force when the clutch plate is forcibly moved through the clutch plate and engaged with the clutch teeth of the final gear, which causes gear noise when changing gears while using a tool. This can be done without causing any damage to the teeth or the clutch teeth, and since no impact is transmitted to the hands through the handle, the gear shifting operation can be performed smoothly, improving the operability of the portable power tool. In addition, in the conventional configuration in which the final gear is moved, it was necessary to provide the intermediate gear that meshes with the final gear with a wide tooth width corresponding to the amount of movement, but with the present invention, the intermediate gear can be used as the final gear. Since the same narrow width is sufficient, the manufacturing cost of the gear is reduced, and it also leads to lighter and more compact gears.When the clutch plates engage and rotate, there is no wasted friction, the resistance is minimal, and the transmission force is strong and smooth. It is efficient and durable, with no wear on parts.

施後の実用的効果は極めて大きい。Furthermore, since the clutch plate is resiliently repelled in the direction in which it engages with the clutch teeth of the final gear, if the switching device is operated in the direction of arbitrary speed change when the tool is stopped, the tool can be started even if the teeth do not engage with the clutch teeth. Clutch engagement occurs naturally when the final gear rotates, which has practical effects such as omitting the conventional operation of manually rotating the spindle to engage the clutch. - The two-stage transmission device of the present invention has extremely great practical effects because it can be formed to a wide width, and there is no place where unnecessary friction occurs between the various parts.
