Definitions

  • the present invention relates to the field of mechanical bearings. More particularly, the invention relates to a bearing assembly specially adapted for rotation movement about a central point, with a large range of movement.
  • Bearings are machine elements that constrain relative motion to only the desired motion, and reduce friction between moving parts. Many types of bearings exist, each designed to handle a specific type of load and allow movement in specific directions. Countless applications require the use of bearings, and the specific type of bearing is chosen in accordance to those parameters.
  • the type of bearing that can be used for this purpose is the spherical bearing which consists of an outer ring or socket (hereinafter referred to as “socket”) and an inner ring or a ball (hereinafter referred to as “ball”), usually connect to a pole, and a locking feature that makes the ball trapped within the socket in the axial direction only. Due to this structure of the spherical bearing, in order to withstand strong forces the socket must accommodate more than half of the ball in order to hold the ball in it, which limits the movement range of the pole.
  • the present invention relates to a bearing assembly adapted to enable movement around three vertical axes and about one spatial point, comprising:
  • a rod connected to an axial bearing and provided with an anchoring portion suitable to be housed in said ring-like element;
  • a holding element connected at its two extremities to said ring-like element, having an inner shape such that allows it to rotate around said ring-like element;
  • the ring-like element is rounded at its internal wall and designed with two straight edges to facilitate connection by the holding element. . .
  • the ring-like element is perforated with two holes designed to connect to the anchoring portion of a rod element by fastener elements.
  • the ring-like element is perforated at two locations for connecting it to the holding element by fastening means.
  • the anchoring portion of the rod is ball shaped.
  • the anchoring portion of the rod is perforated to permit connection to the ring-like element.
  • the holding element is C-shaped or U-shaped.
  • the holding element is provided with an integral connecting element located at its center.
  • the holding element is perforated at each of its extremities for connection to the ring-like element.
  • the invention relates to a bearing device adapted to enable movement around two vertical axes, comprising:
  • a holding element connected at its two extremities to said ring-like element, having an inner shape such that allows it to rotate around said ring-like element;
  • the ring-like element is rounded at its internal wall and designed with two straight edges to facilitate connection by the holding element.
  • the ring-like element is perforated with two holes designed to connect to the anchoring portion of a rod element by fastener elements.
  • the ring-like element is perforated at two locations for connecting it to the holding element by fastening means.
  • the anchoring portion of the rod is ball shaped. According to still another embodiment of the invention, the anchoring portion of the rod is perforated to permit connection to the ring-like element. According to still another embodiment of the invention, the holding element is C-shaped or U-shaped. According to still another embodiment of the invention, the holding element is provided with an integral connecting element located at its center. According to still another embodiment of the invention, the holding element is perforated at each of its extremities for connection to the ring-like element.
  • the invention in another aspect, relates to a positionable assembly, comprising:
  • positionable it is meant to indicate that the assembly of the invention can be caused to assume a desired position.
  • the bearing assembly is connected to the pole by fastening means.
  • the rod is bent.
  • the rod is straight. . .
  • the positionable assembly further comprises a second bearing assembly located at an opposed extremity to the first bearing assembly.
  • Fig. 1 is an isometric view of a bearing assembly, comprising a bearing device and an axial bearing, according to an embodiment of the present invention
  • Fig. 2 schematically illustrates a bearing assembly comprising the bearing device of Fig. 1 and a different axial bearing, according to another embodiment of the invention
  • Fig. 3 is an isometric view of an example of use of the invention, consisting of an arm assembly comprising two bearing assemblies, one according to Fig. 1 and one according to Fig. 2, and a connecting rod;
  • Fig. 4 is an isometric view of a bearing assembly according to another embodiment of the invention.
  • Fig. 5 is an isometric view of a bearing assembly according to yet another embodiment of the invention.
  • Fig. 6 is an isometric view of an arm assembly according to an embodiment of the present invention.
  • the bearing assembly of the invention is designed to enable movement around three vertical axes and about one spatial point.
  • the bearing assembly of the invention is designed with a unique structure, resulting in a significantly greater range of movement.
  • Bearing assembly 101 consists of a bearing device 113 and of an axial bearing 110.
  • Assembly 101 is capable of moving along three axes: axis X, corresponding to pin 104, axis Y, corresponding to pin 106 and axis Z, corresponding to ball connecting rod 109, designed to be vertical to one another and intersect at the same point - the origin located on line 112 (the origin itself cannot be shown). For each of the three axes there is a component designated to turn around it.
  • FIG. 2 illustrates a bearing assembly 201, according to another embodiment of the invention, comprising bearing device 113 as described with reference to Fig. 1, and an axial bearing 210 that is different from axial bearing 110, and is chosen as per the type and intensity of load that bearing assembly 201 is required to handle.
  • bearing assembly 101 is not limited to the components shown in Figs. 1 and 2 and can be of varied shape and size and may employ different components, such as rods, pins, bearings and the like, to allow to handle different types and intensity of load, and to meet specific requirement needed for any given application.
  • Fig. 3 is an isometric view of an arm assembly 301 comprising two bearing assemblies 101 and 201, and a connecting rod 302.
  • Rod 302 is a hard element that can be straight or bent to any required shape.
  • rod 302 is connected to bearing assembly 101 at one end, and to bearing assembly 201 at the other, by pins 303.
  • the connection of rod 302 to bearing devices 101 and 201 grants arm assembly 301 the ability to move in wide range with many degrees of freedom, to allow reaching a desired unique form required by an application.
  • Fig. 4 is an isometric view of a bearing assembly 401 according to another embodiment of the invention that is similar to bearing assemblies 101 and 201 shown in Figs. 1-3, with the difference that instead of pin 104 (e.g. in Fig. l) that is removed, assembly 401 comprises a fastening element 404 configured to keep and lock bolt 105 in place.
  • the other parts, the rotation and the inter-relations between the parts of bearing assembly 401, as well as its form of use are all similar to those of bearing assemblies 101 and 201.
  • This embodiment affords additional freedom around the Z axis due to the removal of pin 104. . .
  • Fig. 5 is an isometric view of a bearing assembly 501 according to yet another embodiment of the present invention, comprising a rod 507 with an anchoring ball 503 at its edge.
  • Ball 503 is connected by a screw 505 to a ring 502 that is configured to rotate around the Y axis of the ball 503.
  • Screw 505 is fastened by fastening nut 506.
  • Axial bearing 504 allows rotation of assembly 501 along the X axis of ball 503.
