    摘要： The disc saw blade has a plurality of arcuate teeth detachably mounted in complementary-shaped arcuate sockets provided in a rim portion around the circumference thereof. Each tooth has a portion butting against a stop, such as a transverse tail stop surface defined by an inward projection of the socket. The configuration provides a small throw entry gap to reduce the likelihood of sticks being thrown. The teeth preferably are detachably mounted by virtue of a tight fit within the sockets, with no use of fasteners to absorb cutting forces. Keying elements such as a male portion of generally rectangular cross-section extending from the socket into a corresponding female portion in the tooth preferably are used to ensure proper alignment of each tooth relative to the plane of the disc saw blade. Preferably, the teeth and sockets are parts of concentric circles, the diameter of the teeth preferably being slightly larger than the diameter of the sockets, thereby producing a press fit. An axial pin may be installed in each tooth through a clearance space within the blade, such that the pin contacts the blade when its tooth rotates slightly away from its installed position, to prevent further rotation away from its installed position. An adapter preferably is used to assist in installation of the teeth, the adapter having a body which is rotatable by a driving tool and having pins or the like extending laterally therefrom to engage the tooth such that the tooth rotates with rotation of the adapter. Preferably, the adapter has an arcuate element secured along one side of its body to ride against a surface of the socket as the tooth is installed, thereby maintaining the tooth in proper engagement with the socket throughout its installation.

    摘要翻译： 盘形锯片具有可拆卸地安装在围绕其圆周的边缘部分中的互补形状的弧形插座中的多个弓形齿。 每个齿都具有与止动件对接的部分，例如由插座的向内突出限定的横向尾部止动表面。 该配置提供了小的投入间隙，以减少投掷棒的可能性。 齿优选地通过紧密配合在插座内可拆卸地安装，而不使用紧固件来吸收切割力。 诸如从插座延伸到牙齿中相应的阴部分的大致矩形横截面的凸形部分的键合元件优选地用于确保每个齿相对于盘锯片的平面的适当对准。 优选地，齿和插座是同心圆的部分，齿的直径优选地略大于插座的直径，由此产生压配合。 轴向销可以通过叶片内的间隙安装在每个齿中，使得当其齿稍微远离其安装位置时，销接触叶片，以防止进一步旋转远离其安装位置。 适配器优选地用于辅助安装牙齿，适配器具有主体，该主体可通过驱动工具旋转，并且具有从其横向延伸的销或类似物以接合齿，使得齿随着适配器的旋转而旋转。 优选地，适配器具有沿其主体的一侧固定的弧形元件，以在安装齿时抵靠插座的表面，从而在其整个安装期间保持该齿与插座正确接合。
