What does a flexure do?
A flexure is a flexible element (or combination of elements) engineered to be compliant in specific degrees of freedom. Flexures are a design feature used by design engineers (usually mechanical engineers) for providing adjustment or compliance in a design.
What is a flexure bearing used for?
Flexure bearings are used in cryocooler compressors and expanders to maintain the ingegrity of the clearance seal between the piston and cylinder.
What is a compliant joint?
Compliant joints, flexure joints, or flexible joints, allow different kinematic DOF between connected parts with a monolithic structure. Some examples of compliant joints are revolute, translational, universal, spherical, and parallelogram quadrilateral joints.
What is a flexible bearing?
Flexible roller bearings have rollers which are not solid but are spirally wound from spring steel strips and machined to a cylindrical profile. This makes the rollers ‘flexible’ and suitable for application where shock or impact loading is frequent.
What is flexural strength?
Flexural strength is the ability of the material to withstand bending forces applied perpendicular to its longitudinal axis.
What is the difference between flexure and bending?
As nouns the difference between bending and flexure is that bending is a motion or action that bends while flexure is the act of bending or flexing; flexion.
Why are compliant mechanisms better?
Better efficiency: Compliant mechanisms do not suffer from some issues that affect multi-bodied mechanisms, such as backlash or surface wear. Due to the usage of flexible elements, compliant mechanisms can easily store energy to be released at a later time or transformed into other forms of energy.
How do compliant mechanisms work?
Compliant mechanisms, like other mechanisms, convert and transmit movements and forces but they accomplish this, at least in part, by the deflection or elastic deformation of their flexible members rather than through the movement of joints alone.
Where are fluid bearings used?
Fluid bearings are frequently used in high load, high speed or high precision applications where ordinary ball bearings would have shortened life or caused high noise and vibration. They are also used increasingly to reduce cost.
Is flexural strength same as breaking strength?
The flexural strength of a material is defined as its ability to resist deformation under load. For materials that deform significantly but do not break, the load at yield, typically measured at 5% deformation/strain of the outer surface, is reported as the flexural strength or flexural yield strength.
What is a tamarack flexure joint?
Tamarack Flexure Joints are lightweight, cost effective, and easy to install in custom and semi-custom thermoplastic and laminated orthopedic bracing applications. Guaranteed for the lifetime of the orthosis in which they were originally installed. Easy to install in custom and semi-custom thermoplastic and laminated orthopedic bracing applications
What is a flexure bearing coupling?
This coupling has two compliant degrees of freedom to allow rotation of the shaft with some misalignment. Many types of flexure bearings are not limited to low loads, however. For example, the drive shafts of some sports cars replace cardan universal joints with an equivalent joint called a rag joint which works by bending rubberized fabric.
What are flexure bearings made of?
Many flexure bearings are made of a single part: two rigid structures joined by a thin “hinge” area. A hinged door can be created by implementing a flexible element between a door and the door frame, such that the flexible element bends allowing the door to pivot open.
What are flexible pipe joints used for?
Designed for piping systems in breweries, food plants, and other sanitary environments, these flexible joints reduce stress, vibration, and noise by absorbing movement. Slip these joints over your pipe ends and tighten the band clamps for a secure hold.
