That is, the roller according to the comparative embodiment has a structure in which the core portion 10 of the roller 100 according to the embodiment, the inner peripheral member 22 of the flange portion 20, and the toothed pulley portion 30 are formed as an integral metal member (this metal The member is referred to as an integral metal member), and a high friction portion 23 made of a rubber material is formed on the outer periphery of the large-diameter portion 101 of the integral metal member. The roller according to the comparative embodiment is manufactured by preparing an integrated metal member by cutting a metal material and casting the rubber material on the outer periphery of the large-diameter portion of the integrated metal member.
比較形態によるローラでは、以下のような課題が生じる。比較形態による一体金属部材は、隣接する大径部１０１間に歯付プーリ部３０の歯面を切削形成することが難しい。また、ゴム材料を流し込んで高摩擦部２３を成形する際に、歯付プーリ部３０の歯の間にゴム材料が入り込み、これを除去することが難しい。 The roller according to the comparative form has the following problems. In the integrated metal member according to the comparative form, it is difficult to cut and form the tooth surface of the toothed pulley portion 30 between the adjacent large diameter portions 101. Further, when the high friction portion 23 is formed by pouring the rubber material, the rubber material enters between the teeth of the toothed pulley portion 30 and it is difficult to remove it.
実施形態によるローラ１００では、芯部１０、鍔部２０、および歯付プーリ部３０が別体の部材となっている。このため、歯付プーリ部３０を、単体で作製できる。つまり、歯付プーリ部３０の歯面は、大径部１０１に干渉されることなく容易に切削形成できる。また、鍔部２０も、単体で作製できる。つまり、鍔部２０に高摩擦部２３（外周部材２３）が形成された後に、鍔部２０と歯付プーリ部３０とが組み立てられるので、歯付プーリ部３０の歯の間にゴム材料が入り込むことがない。このように、実施形態によるローラ１００は、芯部１０、鍔部２０、および歯付プーリ部３０が組み立てられた構造により、作製しやすいという効果を有する。 In the roller 100 according to the embodiment, the core part 10, the flange part 20, and the toothed pulley part 30 are separate members. For this reason, the toothed pulley part 30 can be produced alone. That is, the tooth surface of the toothed pulley portion 30 can be easily cut and formed without being interfered by the large diameter portion 101. Moreover, the collar part 20 can also be produced alone. That is, after the high friction portion 23 (outer peripheral member 23) is formed on the flange portion 20, the flange portion 20 and the toothed pulley portion 30 are assembled, so that the rubber material enters between the teeth of the toothed pulley portion 30. There is nothing. As described above, the roller 100 according to the embodiment has an effect that it is easy to manufacture due to the structure in which the core portion 10, the flange portion 20, and the toothed pulley portion 30 are assembled.
さらに、実施形態によるローラ１００は、以下に説明するように、組み立てやすいという効果も有する。芯部１０は、外径が一定の円筒形状を有し、複数設けられる鍔部２０は、同一形状を有する。このため、各鍔部２０を芯部１０の外周上に順に挿通させるだけで、ローラ１００の大径部１０１と小径部１０２とを構成できる。また、各鍔部２０は同一形状を有しているので、複数の大径部１０２を構成するために、一種類の部品（鍔部２０）を複数個作製すればよい。 Furthermore, the roller 100 according to the embodiment also has an effect that it is easy to assemble as described below. The core portion 10 has a cylindrical shape with a constant outer diameter, and the plurality of flange portions 20 provided have the same shape. For this reason, the large-diameter portion 101 and the small-diameter portion 102 of the roller 100 can be configured only by inserting each flange portion 20 sequentially on the outer periphery of the core portion 10. Moreover, since each collar part 20 has the same shape, in order to comprise the some large diameter part 102, what is necessary is just to produce two or more types of one kind components (the collar part 20).
図３（ｂ）を参照して説明したように、両側の鍔部２０で歯付プーリ部３０が挟まれた構造は、下側の鍔部２０と歯付プーリ部３０と上側の鍔部２０とを積み重ねることで容易に作製できる。この際、歯付プーリ部３０がスペーサとして働くことで、歯付プーリ部３０の両側の鍔部２０を、適切な間隔を空けて配置できる。 As described with reference to FIG. 3B, the structure in which the toothed pulley portion 30 is sandwiched between the flange portions 20 on both sides is the lower flange portion 20, the toothed pulley portion 30, and the upper flange portion 20. Can be easily manufactured. At this time, since the toothed pulley portion 30 functions as a spacer, the flange portions 20 on both sides of the toothed pulley portion 30 can be arranged with an appropriate interval.
また、図３（ｂ）および図３（ｃ）を参照して説明したように、作業台２００上に載置された芯部１０に鍔部２０を挿通すること、あるいは、作業台２００上に載置された鍔部２０に芯部１０を挿通することで、芯部１０の側面と鍔部２０の側面とが揃った（面一となった）構造を容易に作製できる。 Further, as described with reference to FIG. 3B and FIG. 3C, the collar portion 20 is inserted into the core portion 10 placed on the work table 200, or By inserting the core portion 10 through the mounted flange portion 20, a structure in which the side surface of the core portion 10 and the side surface of the flange portion 20 are aligned (equal to each other) can be easily manufactured.
