【考案の詳細な説明】
本案は履帯の駆動輪、すなわちクローラ走行装置におけ
る駆動歯輪取付構造の改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of the drive wheel of a crawler belt, that is, the drive tooth wheel mounting structure in a crawler traveling device.
すなわち、駆動軸に対して駆動輪のボス部をスプライン
嵌合せしめて着脱自在に構成しかつ、その駆動軸のスプ
ライン部を、駆動軸に嵌装されたシールカラーの内径よ
りも大径としたものである。That is, the boss part of the drive wheel is spline-fitted to the drive shaft so that it can be attached and detached freely, and the spline part of the drive shaft has a larger diameter than the inner diameter of the seal collar fitted to the drive shaft. It is.
従来のトラクタ等の履帯は後方の駆動輪で駆動され、前
方には履帯に一定の張力を保たせるための遊動輪を装し
、これと駆動輪の中間には数個の軌道転輪をおいて軌道
台枠により支持している。The tracks of conventional tractors are driven by a rear drive wheel, and an idler wheel is installed at the front to maintain a constant tension on the track, and several track wheels are placed between this and the drive wheels. It is supported by a track frame.
しかるに駆動輪は駆動軸と一体的に形成されているため
突歯が切損すると駆動軸と共に駆動輪を取替えなければ
ならないという労作があり、しかもこの際ケース内の油
を抜いて作業しなければならないという不便があった。However, since the drive wheel is formed integrally with the drive shaft, if the protruding teeth break, the drive wheel must be replaced along with the drive shaft, which is a laborious process.Moreover, the oil in the case must be drained before work is done. This was an inconvenience.
本案はこれを改良したもので駆動軸に対して駆動輪のボ
ス部をスプライン嵌合せしめて着脱自在に構成し、駆動
輪の突歯が切損したとき駆動輪のみを交換できるように
したもので、しがもこの除油を抜くことなく交換が平易
に行なえるようにしたものである。This project is an improvement on this, in which the boss part of the drive wheel is spline-fitted to the drive shaft so that it can be attached and detached freely, so that only the drive wheel can be replaced when the protrusion of the drive wheel breaks off. However, this oil remover can be easily replaced without removing it.
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図は従来の履帯の駆動輪取付構造を示すもので、駆
動輪１の突歯１ａは履板２の突歯２ａに係合するように
なっている。FIG. 1 shows a conventional crawler track driving wheel mounting structure, in which the protruding teeth 1a of the driving wheel 1 engage with the protruding teeth 2a of the track plate 2.
駆動軸３は駆動輪１と一体的に形成され、ケース４の軸
受５，６で支持されて歯車７，８伝動により駆動される
。The drive shaft 3 is formed integrally with the drive wheel 1, is supported by bearings 5 and 6 of the case 4, and is driven by gears 7 and 8.
か・る従来の駆動輪１はその突歯１ａが切損すると軸３
と共に取替えなければならない。If the protruding teeth 1a of the conventional drive wheel 1 break off, the shaft 3 will break.
It must be replaced with the same.
その際シール部分も一緒に外ずれるのでケースの油が外
部にもれる恐れがあり、したがってケースの油を抜いて
から駆動輪の取替えを行なっていた。At this time, the seal part also comes off and there is a risk that the oil in the case may leak to the outside, so the oil in the case must be drained before replacing the drive wheel.
しかるに、第２図に示す本案のものによれば駆動輪を容
易に交換しうるものである。However, according to the present invention shown in FIG. 2, the drive wheels can be easily replaced.
すなわち、駆動輪１のボス部１ｂを駆動軸３の端部にス
プライン嵌合せしめて着脱自在に構成した。That is, the boss portion 1b of the drive wheel 1 is spline-fitted to the end portion of the drive shaft 3 so as to be detachable.
９はそのスプラインである。このスプライン部は後述す
るシールカラー１４の内径より大となっており、駆動輪
１を取外すしてもシールカラー１４は外ずれることがな
く、したがってケースの油が漏れることがない。9 is its spline. This spline portion is larger than the inner diameter of a seal collar 14, which will be described later, so that even if the drive wheel 1 is removed, the seal collar 14 will not come off, so oil from the case will not leak.
ボス部１ｂの締付は座金１０を介してナツト１１で締付
けられるもので軸３と一体的に形成されたボルト１２に
ナツト１１が螺合される。The boss portion 1b is tightened with a nut 11 through a washer 10, and the nut 11 is screwed onto a bolt 12 formed integrally with the shaft 3.
第２図中１３はケースであってこれに軸受１５を介して
駆動軸３が軸架されている。Reference numeral 13 in FIG. 2 denotes a case, on which the drive shaft 3 is mounted via a bearing 15.
１４は駆動輪１のボス１ｂ部に当接するカラーで゛あっ
てこれとケース１３との間には防水のための７０−テン
グシールが施されている。Reference numeral 14 denotes a collar that comes into contact with the boss 1b of the drive wheel 1, and a 70-length seal is provided between this collar and the case 13 for waterproofing.
１６．１７はそのリング、１８゜１９はそのパツキンを
示す。16.17 indicates the ring, and 18° and 19 indicate the gasket.
以上の如く本案のものは駆動軸から駆動輪を自由に取外
すすことができるようにスプライン嵌合しており、しか
も、スプライン部がシールカラーの内径より大となって
いるので、駆動輪の交換を油を抜くことなく容易に行な
うことができるという特徴がある。As mentioned above, the proposed model uses spline fitting so that the drive wheel can be freely removed from the drive shaft, and since the spline part is larger than the inner diameter of the seal collar, the drive wheel can be replaced easily. It has the characteristic that it can be easily carried out without draining the oil.
第１図は従来の駆動輪取付構造の切断面図。 第２図は本案駆動輪取付構造の切断面図である。 FIG. 1 is a cross-sectional view of a conventional drive wheel mounting structure. FIG. 2 is a sectional view of the proposed drive wheel mounting structure.
