【発明の詳細な説明】 産業上の利用分野 本発明は、樹脂製のスラストワッシャの製造法に関す
る。TECHNICAL FIELD The present invention relates to a method of manufacturing a thrust washer made of resin.
従来の技術 樹脂製のスラストワッシャは、トランスミッションのリ

することが行なわれている。2. Description of the Related Art Since a resin thrust washer is used as a sliding material between a retainer of a transmission and a transmission case, sliding characteristics, dimensional accuracy, and strength are required. Usually, asbestos paper or cotton cloth is used as the base material, while transferring these long base materials, phenol resin varnish is continuously applied to this, and the prepreg obtained by drying is punched into a product shape, and a predetermined number ( (20 to 50 sheets) are stacked and heat-processed and molded.
ところで、前記プリプレグには、塗工時の歪が残留して
いる。これは、長尺の基材を、これにテンションをかけ

因となっている。トランスミッションへの組込み後は、
熱、湿気、油分の影響により、更に反りが拡大し、スラ
ストワッシャの異常摩耗、クランク割れ等が発生する。By the way, the strain during coating remains in the prepreg. This is a stress caused by transferring a long base material while applying tension to the long base material, coating and drying the phenol resin varnish. This strain remains until after the thrust washer is molded, which causes a large warp in dimensional accuracy and holding. After being installed in the transmission,
Due to the influence of heat, moisture, and oil, the warp further expands, causing abnormal wear of the thrust washer and cracking of the crank.

このような観点から、製品形状に打抜いた多数のプリプ
レグをランダムに混ぜ合せ、これを所定枚数重ねて加熱
加圧成形することが行なわれている。In order to suppress the warpage of thrust washers, when stacking a specified number of prepregs punched into the manufacturing shape, stack them by changing the vertical and horizontal directions of the base material, changing the front and back surfaces, and canceling the remaining strain in each prepreg. You can do it like this.
From this point of view, a large number of prepregs punched into a product shape are randomly mixed, and a predetermined number of the prepregs are stacked and heat-pressed.
発明が解決しようとする課題 しかし、ランダムに混ぜ合せた製品形状のプリプレグを
一枚一枚揃えて積み重ねる作業には、多大な工数を要す

てプリプレグを積み重ねる工数を低減し、樹脂製のスラ
ストワッシャを効率よく製造することである。However, a large number of man-hours are required for the work of aligning and stacking the prepregs of product shapes that are randomly mixed together one by one. An object of the present invention is to efficiently manufacture resin-made thrust washers by reducing the man-hours for stacking prepregs by changing the front and back directions of the base material in the vertical and horizontal directions.

グを加熱加圧成形するものである。From this, a large number of prepregs are punched into a predetermined thrust washer shape, and the prepregs that have been punched in a stack are integrated with each other by the pressure during punching. Then, the integrated prepreg is heated and pressed.

く、その工数が大幅に低減される。Effect In the method according to the present invention, the individual prepregs punched into the thrust washer shape are not stacked one by one, but when the prepreg is in a work size, the vertical and horizontal directions of the base material Change and stack. Then, when a large number of them are punched out into a thrust washer shape, they are temporarily integrated by the pressure. Therefore, it is not necessary to stack the prepregs for each thrust washer, and the number of steps is greatly reduced.

ばよい。Example When a predetermined number of stacked prepregs were punched into a thrust washer shape, in order to integrate the prepregs with the pressure during the punching, a thermosetting resin varnish was applied to the sheet-shaped substrate and dried when dried. The amount of residual volatile matter may be appropriately adjusted in the process.
