| 連続可変トランスミッション用のプッシュベルトにおいて適用するための横方向エレメントの本体面(11)に凸面状の傾斜ゾーン(23)を形成する方法は、段付き面を有するダイ(30)を提供するステップと、ダイ(30)を本体面(11)に対して圧力をかけながら配置するステップとを含む。しかしながら、ダイ(30)は、傾斜ゾーン(23)が形成される必要がある領域のすぐ外側で第1の本体面(11)に対して押し付けられる。ダイ(30)を適用することによって、凹まされた領域(27)が本体面(11)に配置され、この領域(27)の上側エッジ(28)に沿って横方向エレメント10の材料の後退が生じる。前述のようにエッジ(28)に隣接してこの形式で得られる後退領域は、傾斜ゾーン(23)として機能するのに適している。 | ||||||

| PURPOSE:To prevent occurrence of laps at the end face of links and to improve the flatness of the end face, by regulating the width of the parallel section of the cutting edge of the trimming die which performs punch trimming at the end face of links to >=1/2 of the width of the end face of links. CONSTITUTION:A blank material 1 which has been subjected to the heating, rough forging, and finish forging is placed on a stripper 4 and a punch 5 is lowered. Then, the blank material is subjected to punch trimming work by a punching die 6 for trimming, whose parallel cutting edge part has a width which is >=1/2 of the width of the end face of the link. In this way, occurrence of fins at the end face of links is prevented and the flatness of the end face is improved. | ||||||

| A track link includes a tread surface, a shoe surface, a communicating part, and a seat formation part. The tread surface comes into contact with a roller for an undercarriage. The shoe surface is disposed on an opposite side from the tread surface. A track shoe is attachable to the shoe surface. The communicating part is disposed between the shoe and tread surfaces. The communicating part passes through the track link in a width direction that is perpendicular to a linking direction, and allows side faces of the track link to communicate in the width direction. The seat formation part is formed on a shoe surface side of the communicating part. A through-hole passes through from the shoe surface to the seat formation part, and a bolt member is disposable in the through-hole. A number track links in a loop are usable in a track of a work vehicle. | ||||||

| A sprocket wheel, which is a machine component configured to slide relative to a bushing while being in contact with the bushing in an outer peripheral surface, includes a base made of a first metal, and an overlay that covers the base so as to constitute the outer peripheral surface. The surface of the overlay constituting the outer peripheral surface has been smoothed. Such a smoothed surface of the overlay makes the sprocket wheel less damaging to the bushing. | ||||||

| The present invention relates to a method for producing a link of a vehicular endless track. According to this method, low-carbon boron steel is selected as a starting material for producing the link. The present invention involves the steps of forging and hot-trimming the link material to form a substantially final link shape. Then, the link material is rapidly cooled so that a metallic crystal structure of the link material is converted to martensite. Next, the link material is tempered at a low temperature. Finally, a pin hole and a bushing hole are machine finished in the link material. | ||||||
