Abstract
Earth-boring tools may include a body and a passively adjustable, aggressiveness-modifying member secured to the body. The passively adjustable, aggressiveness-modifying member may be movable between a first position in which the earth-boring tool exhibits a first aggressiveness and a second position in which the earth-boring tool exhibits a second, different aggressiveness responsive to forces acting on the passively adjustable, aggressiveness-modifying member.
Claims17
An earth-boring reamer, comprising:
- a blade;
- and
- a passively adjustable, aggressiveness-modifying member located on the blade, the passively adjustable, aggressiveness-modifying member being movable between a first position in which the reamer exhibits a first aggressiveness and a second position in which the reamer exhibits a second, different aggressiveness responsive to forces acting on the passively adjustable, aggressiveness-modifying member, the passively adjustable, aggressiveness-modifying member configured to modify a depth of cut of cutting elements secured to the blade of the reamer in response to forces applied to the passively adjustable aggressiveness-modifying member as the cutting elements engage with an earth formation.
A method of passively adjusting an aggressiveness of a reamer, comprising:
- causing a force to be exerted on a passively adjustable, aggressiveness-modifying member secured to a blade;
- and
- moving the passively adjustable, aggressiveness-modifying member from a first position in which the reamer exhibits a first aggressiveness to a second position in which the reamer exhibits a second, different aggressiveness responsive to causing the force to act on the passively adjustable, aggressiveness-modifying member by modifying a depth of cut of cutting elements secured to the blade of the reamer in response to forces applied to the passively adjustable, aggressiveness-modifying member as the cutting elements engage with an earth formation.
