構成してある移動農機の伝動構造に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention involves inserting an output power transmission shaft into a transmission cylinder shaft interlockingly connected to a speed reduction mechanism or a transmission mechanism, and connecting the end of the transmission shaft and the cylinder shaft. A transmission pawl is interposed so as to be movable in the radial direction, and by shifting a shift sleeve fitted onto the cylindrical shaft, the pawl is pushed radially inward and engaged across the cylindrical shaft and the transmission shaft. The present invention relates to a transmission structure for a mobile agricultural machine having a pole clutch that can be switched between a transmission state in which the pawls are brought together and a transmission release state in which the poles are allowed to move radially outward and separated from the transmission shaft.
支軸型エンジンを直結搭載した移動農機にあつては、エ
ンジンからの出力軸が下向き姿勢に配置されているので
、実開昭６０−１６６１８号公報に示すように通常は出
力用伝動軸がエンジン出力軸の同軸線上もしくは出力軸
と平行に配置されている。In the case of mobile agricultural machines that are directly equipped with a spindle-type engine, the output shaft from the engine is placed in a downward position, so the output transmission shaft is usually connected to the engine, as shown in Japanese Utility Model Application Publication No. 16618/1983. It is arranged on the same axis of the output shaft or parallel to the output shaft.
前記のように出力用伝動軸の配置が上下姿勢に規制され
るため、車軸を前後移動させることで機体のバランスを
とろうとすれば、ベルト伝動機構などの特別な伝動構造
が必要となって移動農機の構造が複雑になるという欠点
があった。As mentioned above, the arrangement of the output power transmission shaft is restricted to the vertical position, so if you try to balance the aircraft by moving the axle back and forth, a special power transmission structure such as a belt transmission mechanism is required. The disadvantage was that the structure of the agricultural machinery became complicated.
また、出力用伝動軸をエンジン出力軸に対して傾斜させ
て配置させようとすれば、ベベルギヤ、自在継手等の方
向変換手段を介在させる必要があって、構造が複雑にな
る上杵製費用も高くなるという欠点があった。In addition, if the output transmission shaft is to be arranged at an angle with respect to the engine output shaft, it is necessary to use a direction changing means such as a bevel gear or a universal joint, which increases the cost of manufacturing the upper punch due to the complicated structure. The drawback was that it was expensive.
本発明は上記の実情に着目して成されたものであって、
その目的とするところは自在接手等の方向変換手段を用

The purpose is to provide a power transmission structure for a mobile agricultural machine that can change the connection angle of the output transmission shaft to the engine output shaft with a simple structure and at low cost without using direction changing means such as a universal joint. be.
Ｅ問題点を解決するための手段〕
本発明の特徴構成は、前記出力用伝動軸の筒軸内への挿
入端に筒軸内で３次元的に回動自在な球状伝動部を形成
し、この球状伝動部の外周面に前記伝動用ポールの係入
用凹部を形成してある点にあり、その作用及び効果は次
の通りである。Means for Solving Problem E] The characteristic configuration of the present invention is that a spherical transmission part that is three-dimensionally rotatable within the cylinder shaft is formed at the insertion end of the output transmission shaft into the cylinder shaft, The spherical transmission portion has a recessed portion for engaging the transmission pawl formed on the outer circumferential surface thereof, and its functions and effects are as follows.
すなわち、出力用伝動軸の筒軸内への挿入端に筒軸内で
８次元的に回動自在な球状伝動部を形成することによシ

とができるものであり、しかもこの球状伝動部の外周面
に伝動用ポールの係入用凹部を形成してあるので、出力
用伝動軸を傾けたとしても支障なくポールクラッチの入
り切シ操作を行うことができる。In other words, by forming a spherical transmission part that is rotatable in eight dimensions within the cylinder shaft at the insertion end of the output power transmission shaft into the cylinder shaft, the output power transmission shaft can be rotated in the longitudinal direction with respect to the cylinder shaft. Furthermore, since a concave part for engaging the transmission pawl is formed on the outer peripheral surface of this spherical transmission part, even if the output transmission shaft is tilted, the pawl clutch can be engaged and disconnected without any problem. You can perform manual operations.
従って、前記のようにポールクラッチ部分を利用するこ

とができるようになった。 その結果、出力伝動軸を前
後方向へ傾けることで機体のバランスをとυ、作業性を
向上することができると共に、機体の高さを下げること
もできるようになった。Therefore, by using the pole clutch part as described above, the output transmission shaft can be tilted and connected to the engine output shaft without using a direction changing means such as a universal joint, and the engine output shaft can take an up-down position. However, the connection angle of the output transmission shaft can now be changed at low cost without complicating the structure. As a result, by tilting the output transmission shaft in the longitudinal direction, it was possible to improve the balance of the aircraft, improve workability, and also lower the height of the aircraft.
しかも、例えば出力伝動軸及びこの出力伝動軸が挿通さ
れる車輪伝動ケースを後方へ傾けて取付けるようにすれ

き、機体に前進力を付与することもできるのである。Moreover, if the output transmission shaft and the wheel transmission case into which the output transmission shaft is inserted are installed tilted backwards, the center of gravity of the aircraft can be positioned forward of the axle, thereby imparting forward force to the aircraft. It can also be granted.
