Description
【0001】[0001]
本考案は、軸の周面に、例えば歯車やプーリなどの円板体を力強く固定するた めの装置に関する。 The present invention relates to a device for strongly fixing a disc body such as a gear or a pulley to a peripheral surface of a shaft.
【0002】[0002]
従来図2のように軸1にチエンホイル2を固定する場合、前記チエンホイル側 面のボス3からねじ込んだビス4を軸1の側面に圧接するか、また図3のごとく チエンホイル5の側面のボス6と軸7との間にキー8を打ち込むかしている。 Conventionally, when the chain wheel 2 is fixed to the shaft 1 as shown in FIG. 2, a screw 4 screwed from the boss 3 on the side of the chain wheel is pressed against the side surface of the shaft 1 or the side boss 6 of the chain wheel 5 as shown in FIG. The key 8 is pressed between the shaft and the shaft 7.

しかし前記の両手段の場合、両チエンホイルの横方向に傾き安定を図るためそ れぞれボスを備えており、このためチエンホイルを形成するときの材料取りに大 きな一体材料が必要で、不経済であった。そこで本考案は前記チエンホイルのご とき円板体を別材料のバンドで固定するようにしたものである。 However, in the case of both of the above-mentioned means, each of the chain wheels is provided with a boss for stabilizing the inclination in the lateral direction, so that a large integral material is required for material removal when forming the chain foil, and It was an economy. Therefore, the present invention is to fix the disc body such as the chain wheel with a band made of another material.

本考案は上記の目的を達成するために、円板体10の中心の穴16に軸13を 挿入すると共に、2個の円形リング19,20を前記円板体10の両面から前記 軸13に嵌め、一側の円形リング19から前記円板体10を通して他側の円形リ ング20に複数の第1ビス21,21をねじ込み両円形リング19,20で円板 体10を締めつける一方、前記両円形リングそれぞれの外周面から内面に向かっ て該円形リングを切断するカット溝18,18を形成し、該両カット溝を隔てた 一側の挿入穴23から他側のねじ穴24に向かって2本の第二ビス25をねじ込 み両円形リング19,20の収縮で軸13を締めつけて構成したものである。 In order to achieve the above object, the present invention inserts a shaft 13 into a hole 16 at the center of the disc body 10 and attaches two circular rings 19 and 20 to the shaft 13 from both sides of the disc body 10. Fit the plurality of first screws 21 and 21 from the circular ring 19 on one side through the disc body 10 to the circular ring 20 on the other side and tighten the disc body 10 with the both circular rings 19 and 20, while The cut grooves 18, 18 for cutting the circular rings are formed from the outer peripheral surface of each circular ring toward the inner surface, and the cut grooves 18, 18 separating the both cut grooves are formed from the insertion hole 23 on one side toward the screw hole 24 on the other side. The second screw 25 of the book is screwed in, and the shaft 13 is tightened by contraction of both circular rings 19 and 20.

軸13の周囲に嵌合うした円板体10と、該円板体を挟持するように設けた一 対の円形リング19,20とを、この3枚の板を貫通する複数のビス21,21 で締めつけて固定する。さらに前記両円形リングの外周面から内面に向かってカ ット溝18,18を形成すると共に、ビスの締めつけで円形リングの直径を縮小 し、両円形リングで軸13を締めつける結果、前記円板体10を軸13に固定す る。 A disc body 10 fitted around the shaft 13 and a pair of circular rings 19 and 20 provided so as to sandwich the disc body are provided with a plurality of screws 21 and 21 penetrating the three plates. Tighten and fix with. Further, the cut grooves 18, 18 are formed from the outer peripheral surface to the inner surface of both circular rings, and the diameter of the circular rings is reduced by tightening the screws, and the shaft 13 is tightened by both circular rings. The body 10 is fixed to the shaft 13.

図1のA及び図1のBに示すように、円周面に多数の歯10を形成した薄い円板 11の中心の穴12に軸13を挿入し、外周面15から中心の穴16の内面に向 かってカット溝18を形成した2個の円形リング19,20を、前記円板10を 挟むように軸13に嵌合うする。そして2本の第一ビス21,21を一側の円形 リング19から円板11を通して他側の円形リング20のねじ穴22にねじ込み 、円板11と2個の円形リング19,20とを一体に固定する。さらに両円形リ ング19,20の周面一部にそれぞれ切欠き室23を形成し、該切欠き室23か らカット溝18の面のねじ穴24に向かって第二ビス25,25をねじ込み、そ の締めつけで直径収縮する円形リング19,20を軸13に固定する。 As shown in FIG. 1A and FIG. 1B, a shaft 13 is inserted into a central hole 12 of a thin disk 11 having a large number of teeth 10 formed on a circumferential surface thereof, and a central hole 16 from an outer peripheral surface 15 Two circular rings 19 and 20 having a cut groove 18 formed toward the inner surface are fitted to the shaft 13 so as to sandwich the disc 10. Then, the two first screws 21, 21 are screwed from the circular ring 19 on one side through the circular plate 11 into the screw holes 22 of the circular ring 20 on the other side, and the circular plate 11 and the two circular rings 19, 20 are integrated. Fixed to. Further, a notch chamber 23 is formed in a part of the peripheral surface of each of the circular rings 19 and 20, and the second screw 25, 25 is screwed from the notch chamber 23 toward the screw hole 24 on the surface of the cut groove 18. Then, the circular rings 19 and 20 whose diameter is reduced by the tightening are fixed to the shaft 13.
【0007】[0007]
円板体10とその両側の円形リング19,20とを第一ビス21で一体化する と共に、両円形リング19,20におけるカット溝18の部分での第二ビス25 の締めつけにより円形リングの直径を収縮し前記軸13に固定するようにしたも のであるから、円板体10及び円形リング19,20をそれぞれ平板により形成 でき、従来の例えばチエンブロックのように歯車の側面にボスを形成する必要が なくなり、材料取りに経済性を発揮する効果がある。 The disc body 10 and the circular rings 19 and 20 on both sides thereof are integrated by the first screw 21, and the diameter of the circular ring is reduced by tightening the second screw 25 at the cut groove 18 portion of both circular rings 19 and 20. Since the disk is contracted and fixed to the shaft 13, the disk body 10 and the circular rings 19 and 20 can be formed by flat plates, respectively, and a boss is formed on the side surface of the gear like a conventional chain block. It eliminates the need for it and has the effect of demonstrating economic efficiency in material acquisition.
