[Industrial field]

本考案は，こま（１）にＶ字形溝（２），また，Ｕ字形溝（３）を形成して，Ｖベルト（４），丸ベルト（４）を掛けて無段変速する可変プーリーに関する。 The present invention relates to a variable pulley in which a V-shaped groove (2) and a U-shaped groove (3) are formed in a top (1), and a V-belt (4) and a round belt (4) are hung on for continuously variable transmission. .

【０００２】[0002]

[Prior art]

従来，可変プーリーのこまに傾斜した滑孔を貫設して平ベルトを掛けるのは知られている（例えば，特開昭６１−１４９６６１公報参照）。 Conventionally, it has been known to hang a slidable hole through a frame of a variable pulley to hang a flat belt (see, for example, JP-A-61-149661).

【０００３】[0003]

[Problems to be solved by the device]

従来の技術で述べた可変プーリーは，平ベルトのみ使用可能であるため伝達能力は少ない問題点を有していた。 The variable pulley described in the conventional technology has a problem in that the transmission capacity is small because only a flat belt can be used.

【０００４】本考案は，こま（１）にＶ字形溝（２），及び，Ｕ字形溝（３）を形成して，伝達力が大いＶベルト（４），丸ベルト（４）を利用した可変プーリーを提供することを目的とする。According to the present invention, a V-shaped groove (2) and a U-shaped groove (3) are formed in a top (1) to use a V-belt (4) and a round belt (4) having a large transmission force. The purpose of the present invention is to provide a variable pulley.

[Means for Solving the Problems]

上記の目的を達成するために，八個等のこま（１）の円周面（９）に対してかご軸（５）の滑孔（６）を傾斜に貫設する，そのこま（１）の円周面（９）にＶ字形溝（２），またはＵ字形溝（３）を成形する。八本等の滑溝（ア）を放射状に貫設した枠板（７），（７）の間にこま（１）と枠留（８）をはめ込みボルト（イ）で組立てプーリー状にして，八本等のかご軸（５）を滑溝（ア），（ア）と滑孔（６）に通し，かご軸（５）の一方に大錐板（ウ）を，反対方に小錐板（エ）を取り付けて円錐かご車状にする。その円錐かご車状に組立てられた大錐板（ウ）と小錐板（エ）の中心孔（オ），（オ），枠板（７），（７）の中心孔（オ），（オ）にシャフト（カ）を差し入れ，大錐板（ウ）と小錐板（エ）をシャフト（カ）に固定し，枠板（７），（７）を横にスライドするようにする。 In order to achieve the above-mentioned object, the slide hole (6) of the car shaft (5) is obliquely provided with respect to the circumferential surface (9) of the eight etc. tops (1). 2) or V-shaped groove (3) is formed on the circumferential surface (9) of FIG. Assemble the top (1) and the frame retainer (8) between the frame plates (7) and (7) that radially extend eight grooves (a) in a radial shape, assemble them with bolts (a) to form a pulley, The cage shaft (5) such as eight is passed through the grooves (a), (a) and the slide hole (6), the large cone plate (c) is provided on one side of the cage shaft (5) and the small cone plate is formed on the opposite side. Attach (d) to make a cone car. Center holes (o), (o), center holes (o), (7), and center holes (o), (7) of the large cone plate (c) and small cone plate (d) assembled in the shape of a cone car. Insert the shaft (f) into (e), fix the large conical plate (c) and the small conical plate (d) to the shaft (f), and slide the frame plates (7) and (7) sideways. .

【０００６】[0006]

[Action]

Ｖベルト（４），または丸ベルト（４）をこま（１）に掛けて，枠板（７），（７）をスライドさせるとこま（１）の全体の円周面（９）は変化し，Ｖベルト（４），丸ベルト（４）からの回転はシャフト（カ）に伝達され変化する。 When the V-belt (4) or round belt (4) is hung on the top (1) and the frame plates (7) and (7) are slid, the entire circumferential surface (9) of the top (1) changes. Rotation from the V belt (4) and the round belt (4) is transmitted to the shaft (F) and changes.
