摘要：
An earth boring drill bit designed for a specific performance, within a finished product tolerance, using components built to a looser manufacturing tolerance. The bit may be assembled by selecting a leg from a plurality of pre-manufactured legs; selecting a bit body from a plurality of pre-manufactured bit bodies, the bit body having a slot for receiving the leg; placing the leg within the slot; and fixing the leg within the slot within the finished product tolerance by placing one or more shims between the leg and the slot. The shims may be used to adjust an axial position, a radial position, and/or a circumferential position of the leg with respect to the slot. The leg and the bit body may be selected, or produced, to ensure the bit will not meet the specification, given the manufacturing tolerance, without the shims.
摘要（中）：
用于特定性能的地镗钻头，在成品容差范围内，使用构建于更宽松制造公差的部件。 可以通过从多个预制腿部选择腿部来组装钻头; 从多个预制的钻头体中选择钻头体，所述钻头体具有用于接收所述腿的槽; 将腿放在槽内; 并且通过将一个或多个垫片放置在腿部和狭槽之间，将腿部固定在成品容差内的狭槽内。 垫片可以用于调节腿部相对于狭槽的轴向位置，径向位置和/或圆周位置。 可以选择或生产腿和钻头体，以确保在给定制造公差的情况下，钻头不符合规格，没有垫片。
