Resilient Shock Or Vibration Absorber Patents (Class 267/136)
  • Patent number: 11268591
    Abstract: A vibrating machine including a first machine part that vibrates in operation, a second machine part connected to an installation area of the vibrating machine, and a vibratory drive. A resilient bearing is arranged between the machine parts and has at least one air spring per support point and at least one compressed air reservoir fluidically connected to the air spring. A throttle is switched intermediate the air spring and the compressed air reservoir. The first machine part bearing has a resonant or natural frequency lower than an operating frequency of the vibrating machine. The bearing system has a frequency-dependent lower stiffness level with high damping at low frequencies, an upper stiffness level with low damping at higher frequencies, and a transition zone at an intermediate transitional frequency. The throttle is dimensioned such that the transitional frequency is close to, preferably slightly above, the resonant or natural frequency.

  • Patent number: 11112056
    Abstract: An elevatable supporting device for bearing a display is provided. The elevatable supporting device comprises an upright, an energy storage element, and a bearing module. The upright includes a first surface and a second surface which is non-parallel to the first surface. The energy storage element abuts against the first surface and the second surface and includes a first arm providing a first resistance and a second arm providing a second resistance. A first included angle is defined between the first arm and the second arm. When the energy storage element moves from the highest position to the lowest position, the first included angle decreases so that one of the first resistance and the second resistance may increase in order to maintain a total effective resistance along the first axis. Accordingly, the display may be able to stop at any position between the highest position and the lowest position.

In one type of apparatus, one or more SMA rings (65) are mounted on brackets (64) on a frame (62, 63) so that shock received by the frame from one direction changes the shape of the rings into ellipses with major chords in a first direction, and shock received by the frame from the opposite direction changes the shape of the rings into ellipses with major chords in a second direction which is at right angles to the first direction. In other types of apparatus, SMA shock-absorbing components (16, 27, 37, 46, 89) are mounted in a frame (11, 12,13,14,15,17, 21, 22, 24, 25, 26, 31, 32, 34, 35, 41, 42, 43, 44, 45, 47) so that the way in which the shock-absorbing component is deformed is independent of the direction of the shock received by the frame.

  • Patent number: 8991799
    Abstract: A shock absorbing assembly (10) has a front plate (12) and a rear plate (14) separated by spacers (16). The plates and the spacers each have holes (18A, 18B), the upper holes (18A) in the front plate preferably being threaded. Fasteners, such as but not limited to threaded rods (22A, 22B) and locknuts (24A, 24B), hold the spacers in position between the front plate and the rear plate. The threaded rods (22A) are screwed into the threaded holes in the front plate but do not protrude from the front face of the front plate. The threaded rods (22A) are secured by locknuts 24A on one end and the threaded rods (22B) are secured by locknuts 24B on both ends. The rear plate also has a pair of engagement plates (20) which position the assembly on the catwalk.

  • Patent number: 8973886
    Abstract: An active vibration control device is provided that is configured to control the position of a body relative to a reference frame. The control device includes sensors that provide input signals corresponding to movement of the body in at least one direction, a rotary rotary actuator configured to control the position of the body, and four-bar linkage connecting the rotary rotary actuator to the body. The linkage converts the rotary motion output from the rotary actuator into a linear motion of the body. The controller, based on the input signals from the reference frame sensors, provides control signals to the rotary rotary actuator which acts through the linkage to position the body in the at least one direction relative to the position of the reference frame.

  • Patent number: 8960390
    Abstract: Provided is a vehicle-mounted active vibration reducing device wherein vibrations in a plurality of directions are reduced by a single dynamic damper. Since an actuator is attached so as to be supported by an elastic member attached to a bracket, the actuator can be used as a mass of a dynamic damper. The moving directions of the actuator are the forward and rearward directions, and are different from the moving directions of the dynamic damper using the actuator as a mass, i.e., the upward and downward directions. Accordingly, vibrations can be controlled in the forward and rearward directions which correspond to the moving directions of the actuator as well as the upward and downward directions which correspond to the moving directions of the dynamic damper.

  • Patent number: 8950513
    Abstract: Apparatus and methods for controlling drill string vibrations and applying a force to a drill bit include a body having a first piston at an uphole end in association with a drill string and a second piston at a downhole end in association with a drill bit. A first biasing member urges the first piston outward to provide a first force in an uphole direction to the drill string. A second biasing member urges the second piston outward to provide a second force in a downhole direction to the drill bit. When vibration from the drill string compresses the first biasing member, the first force resists the vibration and maintains the apparatus and drill bit in a consistent orientation. When an uphole force from the drill string or the drill bit compresses the second biasing member, the second force prevents movement of the drill bit in an uphole direction.

  • Patent number: 8950739
    Abstract: The first corner portion elastically deforms in application of load such that the angle of the first corner portion changes depending on the pressing force from the first member. In this case, the first corner portion can move toward the outside of the inner periphery portion of the main body portion while the angle changes. The second corner portion has the same function as that of the first corner portion, and it can move toward the outside of the outer periphery portion of the main body portion while the angle changes depending on the pressing force from the second member in the elastic deformation of the second corner portion. As a result, the spring can prevent generation of hysteresis in load characteristics without increasing the number of parts, and enables height adjustment of the spring.
