本考案は、トラツクピンにおける給油孔の密封
栓に関する。[Detailed Description of the Invention] The present invention relates to a sealing plug for an oil supply hole in a track pin.
ブルドーザ等の履帯を備えた装軌式車両におい
て履帯は隣接するリンクとトラツクピンで連結し
て構成される。 In tracked vehicles such as bulldozers, the tracks are connected to adjacent links using track pins.
このトラツクピンは各リンクを圧入したブツシ
ユの中に挿入されており、相互に回動自在に組立
てられ履帯を屈折可能としている。 This track pin is inserted into a bush into which each link is press-fitted, and is assembled so as to be rotatable with respect to each other, so that the track can be bent.
従つてトラツクピンとブツシユ間は摩耗防止の
ために潤滑されることが望ましく、従来において
はトラツクピン内に給油孔を設け、トラツクピン
端面から潤滑油を給油し、給油口をテーパプラグ
で塞いで密封する構造をとつていた。しかしなが
らこの構造においては次の欠点を有する。 Therefore, it is desirable to lubricate the space between the track pin and the bush to prevent wear. Conventionally, an oil supply hole is provided in the track pin, lubricating oil is supplied from the end face of the track pin, and the oil supply port is closed and sealed with a taper plug. I was taking it. However, this structure has the following drawbacks.
(1) テーパプラグはシールテープを巻いてトラツ
クピンの給油口にねじ込むために潤滑油補給時
に手間がかかる。(1) Taper plugs require a lot of effort when replenishing lubricating oil because they are wrapped in sealing tape and screwed into the oil filler port of the track pin.
(2) 給油口にテーパねじを加工する工数がかか
る。(2) It takes a lot of man-hours to machine a tapered thread in the oil filler port.
そこで本考案は密封潤滑式リンクのトラツクピ
ンに設けられる給油孔を密封する栓にかかり前記
欠点を除去し給油孔の加工を安く、組立が簡単か
つ油の補給を容易に可能にする密封栓を提供する
ことを目的としたものである。 Therefore, the present invention provides a sealing plug for sealing the oil supply hole provided in the track pin of a sealed lubricated link, which eliminates the above-mentioned drawbacks, makes the process of the oil supply hole inexpensive, easy to assemble, and facilitates replenishment of oil. It is intended to.
本考案の特徴とする処はトラツクピン用給油孔

の栓部が簡単な形状に出来、栓の組立が圧入式で
容易であるため生産性がある。さらに油の補給が
密封栓を取り外すことなく、かつ新しい部品との
交換もなく容易に可能である。 The feature of this invention is that the sealing plug of the track pin oil supply hole is made of natural rubber or synthetic rubber, and a hole and slit are formed in the center to allow easy replenishment of oil with a lubricant needle. The slit in the hard rubber layer on the outer layer prevents it from easily slipping or falling out, and the slit in the center is a stopper that allows the compressive force from the press-fit to completely close the slit due to the elasticity of the rubber. The plug part of the hole can be made into a simple shape, and the plug can be easily assembled by press-fitting, which improves productivity. Furthermore, oil can be easily replenished without removing the sealing plug or replacing it with a new part.

る。 In the figure, 1 and 2 are adjacent links, and 3 is a bush into which links 2 and 2' are press-fitted.A track pin 4 is inserted into the bush 3, and the links 1 and 2 are press-fitted from both ends.
The crawler track links are formed by press-fitting and connecting the parts 1'. The bush 3 and the track pin 4 are rotatably provided. Reference numeral 5 denotes an oil supply hole provided in the track pin 4, with one end opening to the outside and the other end opening to the sliding surface with the bush 3. A plug 7 is fitted into the external opening of the oil supply hole 5 and seals the oil supply hole 5.

に圧入される。 The stopper 7 is made of natural rubber or synthetic rubber and has an outer layer 7a, an inner layer 7b, a slit 7c, and a hole 7d. The outer layer portion 7a is formed to be hard and the inner layer portion 7b is formed to be soft. For example, the outer layer portion 7a has a rubber hardness of durometer "A" 50.
~80 Inner layer 7b has rubber hardness durometer “A” 20
~40 is suitable. The plug 7 formed of two layers, hard and soft, is connected to the oil supply hole 5 of the track pin 4.

止する。 The sealing plug 7 configured in this way has an outer layer 7a made of hard rubber, an outer diameter larger than the oil supply hole 5, and a crimped opening that utilizes the elastic force of the rubber in a press-fit state to prevent it from coming off. It is fixed in a fixed position so that it does not move. In addition, the inner layer portion 7b has an oil supply hole 5.
It has a slit 7c and a hole 7d so that the lubricating needle 8 attached to the tip of the lubricating device 9 can be easily inserted when the oil accumulated in the lubricating device 9 is exhausted. The compressive force of the state closes the slit 7c, sealing the oil and shutting it off from the outside, thereby preventing muddy water etc. from entering the hole 7d.
