部隙間調整装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sliding part clearance adjustment device for civil engineering machinery, etc., and particularly for fine clearance adjustment of the cutting edge line of a cutting cutter, etc., and for lateral clearance adjustment of a rotating body, etc. This invention relates to a sliding part gap adjustment device that prevents the occurrence of shaking, warping of the connection sh4, etc.

階的な調整を行って摺動部間間のガタ発生を阻止してい
た。(Prior art) Conventionally, in energy transmission mechanisms for transmitting powerful mechanical motions such as those used in civil engineering machinery, strong torsional stress is generated between a sliding body consisting of a connecting body, a rotating body, etc., and its support frame. As a result, the cutting edge line of the cutting cutter may become uneven, or vibration may be generated in the sliding gap between the sliding body and its support frame, causing an enhanced resonance vibration of the civil engineering machine, etc., and causing damage to the machine. The entire structure would oscillate and become unstable, or the vibration would cause noise pollution problems such as abnormal vibrations and noise. As a countermeasure to this problem, shims made of a plurality of thin metal pieces are forcibly inserted between the sliding parts to perform stepwise adjustment and prevent the occurrence of play between the sliding parts.
（発明が解決しようとする問題点）

毎の隙間調整しかできなく摺動部間間のりニア−な微調
整を行うことができなかった。(Problems to be Solved by the Invention) However, as mentioned above, in order to correct the edge line of cutting cutters such as civil engineering machines and to prevent the occurrence of dust between sliding parts,
Shim (the thickness of one shim is usually 0°5LLIIa or more)
For example, with the conventional technology for inserting 0.5 mm
, 1.0 mm, 1.5+n+n and 0.5 mm intervals, and it was not possible to perform near-fine adjustment of the distance between the sliding parts.
また、摺動部間間にシムを挿入する場合、この隙間が大
きくなる度に新たに別のシムを追加挿入しなければなら
ず、さらにその挿入にはハンマー等により挟部がら打撃
挿入するという繁雑な作業を多数回に亘って行う必要が
あった。In addition, when inserting a shim between the sliding parts, each time the gap becomes larger, a new shim must be inserted, and the inserting process involves hitting the sandwiched part with a hammer or the like. It was necessary to perform complicated work multiple times.
一方、隙間調整を微細に行うべくシムを非常に薄いもの
とした場合には、該シムの摺動接触によす摩耗破損が多
発してその繁雑かつ多整備時間を要する取換作業の回数
が頻繁になり実益のないものとなってしまう。On the other hand, when the shims are made very thin in order to finely adjust the gap, the shims often wear out and break due to sliding contact, which increases the number of times the shims have to be replaced, which is complicated and requires a lot of maintenance time. This becomes frequent and becomes unprofitable.
さらに、前記切断用カッターの刃先線を調整する場合、

が動がなくなってしようという問題が生じる。Furthermore, when adjusting the cutting edge line of the cutting cutter,
Install multiple shims between sliding parts in stages (for example, 0.5 ro
As a result, the overlap of the cutter blade edges is too loose and the cutting ability is extremely reduced, or
Alternatively, on the other hand, if the blade edges overlap too tightly, excessive contact resistance will occur, causing the problem that the blade edges will remain stationary for a long time even when a large load is applied.

。(Means for Solving the Problems) The present invention has been made in view of the above-mentioned problems, and includes fine gap adjustment of the cutting edge line of a cutting cutter for civil engineering machinery, etc., and connection of mechanical movements of excavators, etc. Sliding part clearance adjustment that reduces sliding part contact resistance, sliding part wear, sliding part noise, etc. by finely adjusting the distance between the sliding part between the rotating body and its support 7 frames. The device includes a female base having a circular through hole in the center and a ring-shaped groove around the outer periphery; A male base plate having a ring-shaped protrusion that can be slidably inserted into the female ring-shaped groove is assembled by fitting the ring-shaped protrusion into the ring-shaped groove. This is a sliding part clearance adjustment device characterized by having an oil fill port and an oil drain port each having a reverse IL valve at the bottom.

な工作を必要とするなどの手間が掛かる。Since the circular through hole is used to loosely insert and support the device of the present invention on the support shaft, the through hole is made circular to correspond to the cylindrical shape of a general support shaft. Depending on the purpose, the through holes may be square or hexagonal. Regarding the circular through-hole, a simple structure without the through-hole can be used for adjustment between sliding parts, but special machining is required at the location where the device is attached to support it. It takes time and effort.

の発生が生じないこと等の理由によるものである。Further, it is preferable that the male base and the female base are made of a material with high strength and oil resistance, and in particular, the entire male base or at least the portion in contact with the mechanical sliding body has high pressure strength and wear resistance. It is preferably made of a high-strength synthetic resin that has a sympathetic nature. This is because there is no abrasion loss even when sliding bodies such as mechanical coupling bodies and rotating bodies are pressed together by the male base with a pressing force of several tons, and the high-strength synthetic resin itself is slightly This is because it expands and contracts to exhibit a buffering effect and reduce wear loss, and also because it does not generate the squeaking sound that occurs when metal-to-metal sliding parts come into contact with each other. It is.

The gap between the sliding parts can be easily finely adjusted.
