Abstract
Official abstract text for this publication.
An electromechanical actuator housing assembly comprising a reinforcement ring is disclosed herein. The design of the electromechanical actuator housing assembly may be directed to improving load measurement accuracy. The design of the electromechanical actuator housing assembly may be directed to reducing housing deflections. A method of manufacture of an EMA housing assembly is also disclosed herein. This method may include an electromechanical actuator housing assembly having a reinforcement ring.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electromechanical actuator (EMA) housing assembly comprising: a reinforcement ring integrally formed in the housing assembly with a retaining surface located axially between the reinforcement ring and a mounting flange of the housing assembly, wherein the retaining surface comprises a polygonal geometry, wherein the reinforcement ring is disposed distal to the mounting flange of the housing assembly, wherein the reinforcement ring has a tapered geometry. 2. The EMA housing assembly of claim 1 , wherein the reinforcement ring comprises a housing geometry that varies across two parallel planes perpendicular an axial centerline of the EMA housing. 3. The EMA housing assembly of claim 1 , wherein the EMA housing is a forged aluminum EMA housing. 4. The EMA housing assembly of claim 1 , wherein a surface of the integral reinforcement ring comprises an exposed surface of the EMA housing assembly. 5. The EMA housing assembly of claim 1 , wherein the maximum stress of the EMA housing assembly measured at 8500 lbs actuation load is less than or equal to 38.7 ksi. 6. The EMA housing assembly of claim 1 , further comprising a surface that bounds a cavity. 7. The EMA housing assembly of claim 1 , wherein the EMA housing assembly is installed on an aircraft. 8. The EMA housing assembly of claim 1 , wherein there is no washer proximate the reinforcement ring.
