摘要： Methods for the fabrication of metal strain wave gear flexsplines using a specialized metal additive manufacturing technique are provided. The method allows the entire flexspline to be metal printed, including all the components: the output surface with mating features, the thin wall of the cup, and the teeth integral to the flexspline. The flexspline may be used directly upon removal from the building tray.

摘要： Methods and alloy systems for non-Be BMG matrix composite materials that can be used to additively manufacturing parts with superior mechanical properties, especially high toughness and strength, are provided. Alloys are directed to BMGMC materials comprising a high strength BMG matrix reinforced with properly scaled, soft, crystalline metal dendrite inclusions dispersed throughout the matrix in a sufficient concentration to resist fracture.

摘要： Systems and methods in accordance with embodiments of the invention operate to structurally interrelate two components using inserts made from metallic glass-based materials. In one embodiment, a method of structurally interrelating two components includes: forming an insert from a metallic glass-based composition; where the formed insert includes a metallic glass-based material; affixing the insert to a first component; and structurally interrelating the second component to the first component using the insert.

摘要： Harmonic drives (HDs) are used widely in robotics as a method for achieving high gear reductions and for driving force transmissions. The HD is made a three components: a wave generator, a flexspline, and a circular spline. Low-cost wave generators for metal strain wave gearing are provided. Wave generators are provided that incorporate commercially available bearings that form an ellipse either statically or through adjustment. Wave generators are optimized to maximum performance, including increasing the efficiency and the lifetime, while maximizing the running torque. The shape, size, number, type and location of the bearings can be changed so that the wave generator fails at a similar lifetime as a low cost flexspline. The shape of the wave generator may be adjusted to change the performance of the strain wave gear. The combination of low-cost flexsplines with low-cost wave generators reduces the cost of the strain wave gear.

摘要： Systems and methods in accordance with embodiments of the invention implement additive manufacturing techniques that employ different sets of deposition characteristics and/or material formation characteristics during the additive manufacture of an object so as to strategically build up the object. In many embodiments, material used to build up an object is deposited at different deposition rates during the additive manufacture of the object, and the object is thereby strategically built up. In one embodiment, a method of additively manufacturing an object includes: depositing material onto a surface at a first deposition rate so as to define a first region of the object to be additively manufactured; and depositing material onto a surface at a second deposition rate so as to define a second region of the object to be additively manufactured; where the second deposition rate is different from the first deposition rate.
