Description
【考案の詳細な説明】
本案は農作業機におけるＰＴＯ軸構造に関するものであ
る。[Detailed description of the invention] The present invention relates to a PTO shaft structure in an agricultural machine.
すなわち、本案は外部ＰＴＯ軸の中心部軸方向に切損箇
所が奥端部分となる衝撃吸収用の中空部を設けたもので
あって、衝撃荷重によるミッション内部の歯車と軸の破
損を防止すべく外部ＰＴＯ軸でロータリーの衝撃を吸収
出来るようにしたものである。In other words, this proposal provides a hollow part for shock absorption in which the breakage point is at the rear end in the central axial direction of the external PTO shaft, and is designed to prevent damage to the gears and shaft inside the transmission due to shock loads. The external PTO shaft is designed to absorb the impact of the rotary.
以下図面に示す実施例について説明する。The embodiments shown in the drawings will be described below.
第１図は農用トラクターの正面図であってエンジン部１
からクラッチハウジング２とトランスミッションケース
３内の伝動機構を経てＰＴＯ軸４に動力が伝達されるよ
うになっており、このＰＴＯ軸４からロータリーを駆動
するようになっている。Figure 1 is a front view of an agricultural tractor, with engine section 1
Power is transmitted from the clutch housing 2 to the transmission mechanism in the transmission case 3 to the PTO shaft 4, which drives the rotary.
なお、図中５はステアリングホイルを、６は座席を、７
，８は前後輪をそれぞれ示し、９，１０．１１．１２は
それぞれトップリンク、ロワリング、リフトリンク及び
リフトアームを示す。In the figure, 5 is the steering wheel, 6 is the seat, and 7 is the steering wheel.
, 8 indicate the front and rear wheels, respectively, and 9, 10, 11, and 12 indicate the top link, lower ring, lift link, and lift arm, respectively.
本案は以上のようなＰＴＯ軸４の外部ＰＴＯ軸４の中心
部に第２図に示すように軸方向の切損箇所が奥端部分４
ｂとなる衝撃吸収用の円筒状の中空部４ａを設けたもの
である。In this case, the cut point in the axial direction is at the center of the external PTO shaft 4 as shown in FIG.
A cylindrical hollow portion 4a for shock absorption is provided as indicated by b.
この中空部４ａは角筒状であってもよいが加工が面倒で
ある。This hollow portion 4a may have a rectangular tube shape, but machining is troublesome.
この中空部４ａはＰＴＯ軸４の軸径に応じてその中空径
を変更する。The hollow diameter of this hollow portion 4a is changed according to the shaft diameter of the PTO shaft 4.
このＰＴＯ軸４の中程には、これとユニバーサルジヨイ
ントとの連結のためのピンの嵌入する環状溝１３がある
。In the middle of the PTO shaft 4, there is an annular groove 13 into which a pin is inserted for connecting the PTO shaft to a universal joint.
以上の如く、中空部４ａを設けると必要以上の衝撃荷重
がかかったときのみ図示のような中空部４ａの奥端部分
４ｂから、時には環状溝１３部分から切損し、ミッショ
ン内部への影響を少なくすることができ、常時は外部Ｐ
ＴＯ軸４でロータリーの衝撃を吸収できるものである。As described above, if the hollow part 4a is provided, only when an impact load larger than necessary is applied, the breakage will occur from the inner end part 4b of the hollow part 4a as shown in the figure, or sometimes from the annular groove 13 part, reducing the impact on the inside of the transmission. can be used, and is always external P
The TO shaft 4 can absorb the impact of the rotary.
したがって部品交換はＰＴＯ軸だけで済み、加工工数の
かかるミッション内部の歯車や軸を変える必要がないの
できわめて低コストで修理ができるという特徴がある。Therefore, only the PTO shaft needs to be replaced, and there is no need to change the gears or shafts inside the transmission, which requires a lot of man-hours, so it can be repaired at an extremely low cost.
第１図は農用トラクタの正面図、第２図はＰＴＯｉ軸部
分の断面図である。
４・・・・・・外部口゛Ｏ軸、４ａ・・・・・・中空部
