Description

【0001】
【発明の属する技術分野】
本発明は駆動軸と従動軸のスプロケットに捲き掛けられたチェーンに、常時適当な緊張力をあたえるテンシュナーレバー、又テンショナーレバーの反対側に配置されるチェーンガイド及びチェーンダンパーにおけるにシューの取り付け構造に関するものである。
【0002】
【従来技術】
図4は一般的なチェーン駆動装置を表しているが、チェーン(イ)は駆動軸(ロ)と従動軸(ハ)に取着しているスプロケット(ニ)、(ホ)に巻き掛けられており、該チェーン(イ)はテンショナーレバー(ヘ)によって押圧されて、適当な緊張力が常時作用している。従って両スプロケット(ニ)、(ホ)の回転と共に走行するチェーン(イ)の振動を抑制し、従動軸(ハ)へ時間の遅れを生じることなく伝達される。また振動を抑制することでチェーン(イ)に作用する衝撃力はなくなり、チェーン寿命を向上させることが出来る。
【0003】
ところで、テンショナーレバー(ヘ)はテンショナー(ト)によって押圧されてチェーン(イ)に作用しているが、このテンショナーレバー(ヘ)の形態には色々あり、一般的には金属製アームにゴム製又は樹脂製のシューが接着されたり、シューがアームと一体的に成形されている。上記シューをアームに接着した場合には剥がれることもあり、又シューをアームと一体成形する場合には成形金型を必要とし、製作コストは高くなる。
【0004】
そこで別々に製作したアームとシューを、接着剤を用いることなく組み立て・固定したテンショナーレバーが知られている。実公平7−36201号に係る合成樹脂製シューを備えたチェーンガイドレールはシューをシュー支持部材に着脱可能に取り付けた構造と成っている。すなわち、シュー支持部材のチェーン走行始端部にシューに形成した端部フック片を係合し、又シューに形成したL字状の側面係合片をシュー支持部材に係合して取着している。
【0005】
このようにシューはシュー支持部材に着脱可能な状態で取り付けられることになるが、シューに形成したL字状の側面係合片をシュー支持部材に係合する作業は面倒であると共に、取り付け構造が複雑化して製作コストは高くなってしまう。
【0006】
【本発明が解決しようとする課題】
このように従来のテンショナーレバーには上記のごとき問題がある。本発明が解決しようとする課題はこれら問題点であって、アームとシューを別々に制作し、該アームにシューを着脱自在に取り付けして構成するものであり、しかも取着構造が簡単であると共に、組み立ても容易で製作コストが安くなるテンショナーレバーにおけるシューの取り付け構造を提供する。一方においては、構造的に共通するチェーンガイド並びにチェーンダンパーも対象にいれる。
【0007】
【課題を解決する為の手段】
本発明が対象とするテンショナーレバーは金属製アームと樹脂製シューを組み合わせ、シューは着脱自在の取り付け構造と成っている。アームは2枚の側板と側板の両端に設けているブシュ又はピン等の連結部から成り、一方の連結部はテンショナーレバーが揺動する為の軸となり、他方の連結部にはテンショナーレバーをチェーン側へ押圧するためのテンショナーが連結する。ここでアームの具体的な構造は特に限定せず、例えば上記連結部と成る両ブシュを側板に形成した穴に圧入することで所定の間隔で並設した構造とすることが出来る。又は両側板と両連結部を一体化して製作することも可能である。
【0008】
そしてチェーンの走行始端部と成る揺動軸側の側板端には係合部を突出して形成している。一方のシューは樹脂製又は硬質のゴム製であり、上記アームに接着剤を用いることなく又ネジなどの止着具を用いることなく取着される。そこでチェーンの走行始端部側にはカギ形をした係合片が形成され、他方側にはツメを形成している。ツメは対を成して両ツメ間にはブシュ等の連結部が嵌る空間を有している。従って、係合片を上記係合部に係止しすると共に、両ツメによって連結部を挟むようにツメ間に形成している空間に嵌める。
【0009】
シューの表側(チェーンが走行する側)には走行するチェーンが外れないようにガイドを両側に突出し、内側(裏側)には凸部を形成している。この凸部はシュー全長にわたって形成してもよいが、複数に分離して設けることもあり、アームの両側板間に嵌ってシューが横ズレしないようにしている。逆に凸部を側板の外側に位置して両凸部の間に側板が嵌るようにすることもある。以下、本発明に係る実施例を図面に基づいて詳細に説明する。
【0010】
【実施例】
図1は本発明に係るテンショナーレバーを示している実施例であり、アーム1とシュー2から成り、両端にはブシュ3とブシュ4を有している。同図の(c)は(a)のA−A断面図、(b)は(a)のB−B断面図をあらわしているが、シュー2はアーム1に簡単に取着されている。
【0011】
図2はアーム1を示しているが、該アーム1は金属製であって、2枚の側板5、5とブシュ3、4から成り、ブシュ3、4は上記側板5,5に形成した穴に嵌って両側板5,5を平行に、しかも所定の間隔をおいて固定する為の連結部材である。そして側板5,5の一方端(チェーン走行始端部)側には突出した係合部6,6を形成している。同図に示しているアーム1は2枚の側板5,5と2個のブシュ3,4を組立てた構造と成っているが、例えばダイキャスト材を削り出して製作することも出来る。図3はシュー2を示している実施例で、樹脂を材質とした成形品であり、一方端には係合片7が、他方端には対を成しているツメ8a、8bを有している。
【0012】
上記係合片7はU形に湾曲してアーム端に形成している係合部6に係合することが出来、そして一対のツメ8a、8bは間の空間9にブシュ4が嵌る。すなわち、ブシュ4を両ツメ8a、8bによって挟みこむことが出来る。シュー2はアーム1の上面10に載り、アーム1から外れないように下面12に形成した凸部11,11を両側板5,5間に嵌めている。同図(b)にC−C断面を示しているように、凸部11は下面12の中央に僅かに突出している。
ここで凸部11をシューの両側に設け、両凸部11,11にて側板5,5を挟みこむことが出来る。
【0013】
一方、シュー2の上面13の両側にはガイド14,14が沿設され、走行するチェーンがテンショナーレバーから外れないようにしている。上記実施例ではテンショナーレバーについて説明したが、チェーンガイド及びチェーンダンパーについては同じてあることから詳細な説明は省略する。以上述べたように、本発明のテンショナーレバー等のシュー取り付け構造は、シュー先端の係合片をアーム端の係合部に係合すると共に、他方に設けた一対のツメをアーム端の連結部を抱くように嵌めたもので、次のような効果を得ることが出来る。
【0014】
【発明の効果】
本発明が対象とするテンショナーレバー、チェーンガイド、チェーンダンパーは金属製アームに樹脂製シューを取り付けして構成したものであり、構造ならびに製作は簡略化されて製造コストは安くなる。すなわち、アーム端に設けた係合部にはシューの係合片が係合すると共に、アーム他端の連結部にはシューに形成した一対のツメが係合して取り付けられる。従ってシューが磨耗した場合には新たなものと交換可能である。そして、係合片と両ツメにて取り付けたシューであるが、下面に設けた凸部がアームの両側板と互いに嵌合してアームから位置ズレして外れることはない。

BACKGROUND OF THE INVENTION
The present invention is a tenshner lever that always applies an appropriate tension force to a chain strung on a sprocket of a drive shaft and a driven shaft, and a chain guide and chain damper disposed on the opposite side of the tensioner lever. Concerning structure.
[0002]
[Prior art]
FIG. 4 shows a general chain drive device. The chain (A) is wound around a sprocket (d) and (e) attached to a drive shaft (b) and a driven shaft (c). The chain (A) is pressed by the tensioner lever (F), and an appropriate tension is constantly applied. Accordingly, the vibration of the chain (A) traveling along with the rotation of both sprockets (D) and (E) is suppressed, and transmitted to the driven shaft (C) without causing a time delay. Further, by suppressing the vibration, the impact force acting on the chain (A) is eliminated, and the chain life can be improved.
[0003]
By the way, the tensioner lever (f) is pressed by the tensioner (g) and acts on the chain (b). There are various forms of the tensioner lever (f), and generally a metal arm is made of rubber. Alternatively, a resin shoe is bonded, or the shoe is formed integrally with the arm. When the shoe is bonded to the arm, the shoe may be peeled off, and when the shoe is integrally formed with the arm, a molding die is required, and the manufacturing cost becomes high.
[0004]
Therefore, a tensioner lever in which separately manufactured arms and shoes are assembled and fixed without using an adhesive is known. The chain guide rail provided with a synthetic resin shoe according to Japanese Utility Model Publication No. 7-36201 has a structure in which the shoe is detachably attached to a shoe support member. That is, the end hook piece formed on the shoe is engaged with the chain running start end of the shoe support member, and the L-shaped side engagement piece formed on the shoe is engaged with and attached to the shoe support member. Yes.
[0005]
As described above, the shoe is attached to the shoe support member in a detachable state, but the operation of engaging the L-shaped side engaging piece formed on the shoe with the shoe support member is troublesome and has an attachment structure. However, the manufacturing cost becomes high.
[0006]
[Problems to be solved by the present invention]
As described above, the conventional tensioner lever has the above-described problems. The problems to be solved by the present invention are these problems. The arm and the shoe are separately manufactured, the shoe is detachably attached to the arm, and the mounting structure is simple. At the same time, a shoe mounting structure for a tensioner lever that is easy to assemble and inexpensive to manufacture is provided. On the one hand, chain guides and chain dampers that are common in structure are also targeted.
[0007]
[Means for solving the problems]
The tensioner lever targeted by the present invention combines a metal arm and a resin shoe, and the shoe has a detachable mounting structure. The arm consists of two side plates and connecting parts such as bushes or pins provided at both ends of the side plate. One connecting part is a shaft for the tensioner lever to swing, and the other connecting part is a chain with a tensioner lever. A tensioner for pressing to the side is connected. Here, the specific structure of the arm is not particularly limited, and for example, a structure in which both bushes serving as the connecting portion are press-fitted into a hole formed in the side plate and arranged in parallel at a predetermined interval can be used. Alternatively, both side plates and both connecting portions can be integrally manufactured.
[0008]
An engaging portion protrudes from the side plate end on the swing shaft side which becomes the running start end portion of the chain. One shoe is made of resin or hard rubber, and is attached to the arm without using an adhesive and without using a fastener such as a screw. Thus, a hook-shaped engagement piece is formed on the running start end side of the chain, and a claw is formed on the other side. The claws form a pair, and a space in which a connecting portion such as a bush fits is formed between the claws. Therefore, the engaging piece is locked to the engaging portion, and is fitted into a space formed between the claws so that the coupling portion is sandwiched between the claws.
[0009]
On the front side of the shoe (the side on which the chain runs), the guide protrudes on both sides so that the running chain does not come off, and on the inner side (back side), a convex portion is formed. This convex portion may be formed over the entire length of the shoe, but may be provided separately in a plurality, and is fitted between both side plates of the arm so that the shoe does not shift laterally. Conversely, the convex portion may be located outside the side plate so that the side plate is fitted between the convex portions. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
[0010]
【Example】
FIG. 1 shows an embodiment of a tensioner lever according to the present invention, which comprises an arm 1 and a shoe 2, and has bushes 3 and 4 at both ends. FIG. 2C is a cross-sectional view taken along the line AA of FIG. 1A, and FIG. 4B is a cross-sectional view taken along the line BB of FIG. 2A. The shoe 2 is simply attached to the arm 1.
[0011]
FIG. 2 shows the arm 1, which is made of metal and is composed of two side plates 5, 5 and bushes 3, 4. The bushes 3, 4 are holes formed in the side plates 5, 5. It is a connecting member for fixing the both side plates 5 and 5 in parallel with each other at a predetermined interval. Further, projecting engaging portions 6 and 6 are formed on one end (chain travel start end) side of the side plates 5 and 5. The arm 1 shown in the figure has a structure in which two side plates 5 and 5 and two bushes 3 and 4 are assembled. However, for example, a die-cast material can be cut out and manufactured. FIG. 3 shows an embodiment of the shoe 2, which is a molded product made of resin, and has an engagement piece 7 at one end and a pair of claws 8a and 8b at the other end. ing.
[0012]
The engaging piece 7 can be engaged with an engaging portion 6 which is curved in a U shape and formed at the end of the arm, and the bush 4 is fitted into a space 9 between the pair of claws 8a and 8b. That is, the bush 4 can be sandwiched between the claws 8a and 8b. The shoe 2 is placed on the upper surface 10 of the arm 1, and convex portions 11, 11 formed on the lower surface 12 are fitted between the side plates 5, 5 so as not to be detached from the arm 1. The convex part 11 protrudes slightly in the center of the lower surface 12, as shown in FIG.
Here, the convex portions 11 are provided on both sides of the shoe, and the side plates 5 and 5 can be sandwiched between the convex portions 11 and 11.
[0013]
On the other hand, guides 14 and 14 are provided on both sides of the upper surface 13 of the shoe 2 so that the traveling chain does not come off the tensioner lever. In the above embodiment, the tensioner lever has been described. However, since the chain guide and the chain damper are the same, detailed description thereof will be omitted. As described above, the shoe mounting structure such as the tensioner lever of the present invention engages the engagement piece at the tip of the shoe with the engagement portion of the arm end, and the pair of claws provided on the other end connects the connection portion of the arm end. The following effects can be obtained.
[0014]
【The invention's effect】
The tensioner lever, the chain guide, and the chain damper that are the subject of the present invention are configured by attaching a resin shoe to a metal arm, and the structure and manufacturing are simplified, and the manufacturing cost is reduced. That is, the engaging piece of the shoe is engaged with the engaging portion provided at the arm end, and a pair of claws formed on the shoe is engaged and attached to the connecting portion at the other end of the arm. Therefore, when the shoe is worn, it can be replaced with a new one. And although it is a shoe attached with an engagement piece and both claws, the convex part provided in the lower surface fits with the both side plates of an arm, and does not slip | deviate from an arm and remove | deviate.
