Description

ASSEMBLY OF SPHERE AND RING WHICH INCLUDES A ONE-PIECE RIVER RING MEMBER INTEGRALLY WITH THE SPHERE Field of the Invention The present invention relates, in general, to a ball and race ring assembly and, more particularly, this invention relates to a ball and race ring assembly having a race ring assembly. rolling of a piece integrally formed on the sphere. This invention has particular utility in the industry for railway couplings for use in connection assemblies which are used in articulated coupling arrangements and tensioner assemblies without clearance.

BACKGROUND OF THE INVENTION Articulated coupling arrangements and non-slack tensor assemblies have been well known in the railway industry for several years as means for connecting together the adjacently placed ends of a pair of rail freight cars in a substantially semi-permanent manner. In other words, those railway freight wagons do not require frequent separation during their service. Normally they will only be separated when a repair is required and / or routine maintenance is performed on one or more of them. These railway wagons are particularly adapted for what is very often known, in the railway industry, as a service of wagon semi-trailers loaded on wagons platform and / or dedicated service where the wagons that are joined in such a semipermanent way are commonly known in the industry. railway as a unit of "5 packages" or "10 packages". Those units of 5 packages or 10 packages do not require the use of a standard coupler except between units. The main reason that such standard couplers are not required, is because those units are only periodically separated. Normally, this occurs when the maintenance and / or replacement of an individual component on one of the wagons must be carried out. Obviously, considerable cost savings are achieved by this semi-permanent coupling arrangement. These cost savings are mainly derived from the lower weight of the wagon, less rail cars, less maintenance and generally lower equipment cost is achieved through the elimination of coupling devices and a reduction in the number of wagons required.

With the use of these semi-permanent coupling arrangements with the higher loads currently being transported by modern trains, it is of more importance that a close relationship be maintained between the numerous coupling components. Such a close relationship is required to reduce the effects of impact forces that are encountered by a car under conditions of sudden interruption of train operations. The articulated coupling device of the above type used for the purpose of connecting the adjacent ends of a pair of wagons, in semi-permanent form, is taught in U.S. Patent No. 5,172,819, the teachings of such a patent are incorporated in the present application by reference this . This particular articulated coupling device includes a male connection member secured to one end of a first railway body and a male connection member secured to an end adjacent to a second railway body. The male connection member includes an opening therein. A bearing assembly, which includes a substantially spherical member, is located within this opening for attaching the male connection member to the female connection member. A raceway assembly, formed by at least two members, is provided within the aperture and is positioned around a predetermined portion of the substantially spherical member. The rolling ring assembly allows the necessary movement of the male connecting member relative to the female connecting member in each of a vertical direction and a horizontal direction over a predetermined range of angles measured from each of a central line of the spherical member placed in a vertical direction and a longitudinal axis of the articulated coupling arrangement placed in a horizontal direction. Insurance means are provided, which can be coupled with each of the rolling ring assembly and the male connecting member to secure the rolling ring assembly and the spherical member to the male connecting member. A typical slack-type tensioner assembly using a ball-and-ring connection assembly comprises the following elements: a wagon connecting member or female connecting member engageable with a rail vehicle, a spherical member securable with the member connecting the wagon, the male connecting member having a curved head and an opening, which is positioned around the secured spherical member within the wagon connecting member and a two-piece rolling ring assembly secured within the opening of the male connection member positioned between the spherical member and such an opening and a tensioner connected to such a male connection member. A disadvantage of the articulated coupling arrangements and non-play tensioner assemblies discussed above is the provision of at least two separate members to form a race ring assembly. These prior arrangements not only require careful machining of the separate pieces that form the correct size ring members, but care must be taken in securing those two members within the opening of the male connecting member around a predetermined portion of the spherical member. Those requirements add additional material costs, assembly time and labor to the manufacture of the connection assembly of the articulated and diagonal coupling arrangement or tensioner assembly without clearance.

Preferably the one-piece rolling ring member is formed integrally with the spherical member by a filament that winds the rolling ring material over the spherical member. The connection assembly of the present invention comprises a substantially spherical member having a predetermined diameter and a one-piece ring member formed integrally with the spherical member, so as to allow rotational movement of the spherical member with respect to the spherical member. One piece rolling ring. A male connection member and a wagon connection member, or female, is provided for the railway coupling device. The male connection member includes an opening at one end.

Detailed Description of the Invention Before proceeding to the more detailed description of the different embodiments of the present invention, it should be noted that, in order to be clearer, identical components that have identical functions have been identified with identical reference numerals. all the different views that have been illustrated in the drawings.

Reference is now made, more particularly, to Figures 1-2 of the drawings, in h a previously preferred embodiment of a connection assembly for use in a coupling arrangement of the articulated type, generally designated, is illustrated. at 10, h is constructed in accordance with the principles of the present invention. This articulated coupling arrangement 10 can be reconverted to existing railway wagons, if desired, and is capable of connecting together, in a substantially semi-permanent manner, at least one predetermined end of a first rail car (not shown) to a adjacent predetermined end of a second rail car (not shown). Such an articulated coupling arrangement 10 generally includes a male connection member, generally designated 20, a female connection member, generally designated 30, a connection assembly, constructed in accordance with the present invention and designated generally as 40, and means, generally designated 50, for attaching the connection assembly 40 to such a coupling arrangement of the articulated type 10 in a semi-permanent manner. The male connecting member 20 is adapted to a first end 12 thereof in such a manner as to allow such male connecting member 20 to engage with and connect to a predetermined end of a central spar member (not shown) positioned substantially at along a longitudinal center line of a first rail car and a second rail car. Before being secured in place, preferably by welding, the first end 12 of the male connecting member 20 is placed within the central spar portion a predetermined distance. Usually this predetermined distance will be approximately 15.24 to 25.4 centimeters (6 to 10 inches) with approximately 20.32 centimeters (8 inches) being preferred and typical. Because the first end 12 of the male connecting member 20 is to be placed within the central rail portion of the rail car, its outer dimensions are substantially controlled by the internal dimensions of such portion of the central beam. The second end 14 of the male connecting member 20 is generally an elongated rectangular shaped element. The outermost end 18 of the second end 14 of the male connection member 20, preferably, it has a convex shape in a plane, which extends in a vertical direction and a horizontal direction. In addition, the lower wall portion 22 of the second end 14 of the male connection member 20 is inclined upwards starting from a predetermined position and extending towards said first end 12. Such an inclined portion has an inclination of at least about 10 degrees. The purpose of this inclined portion of the lower wall 22 of the male connecting member 20 is to allow bending in a horizontal plane when the wagons are moving over mountainous terrain. Positioned within the second end 14 of the male connection member 20 is an opening 16 having a predetermined size and a predetermined configuration. This opening 16 is formed through a predetermined portion of the second end 14 with the male connection member 20 to form an internal surface 17 with this male connection member 20. The opening 16 has a longitudinal axis that is positioned transverse to an axis longitudinal of the male connection member 20 and is in a substantially horizontal plane. The female connection member 30 includes a first end 24, which is configured in such a way as to allow such a female connection member 30 to engage and connect to a predetermined adjacent end of a member of the center member (not shown) positioned substantially along a longitudinal center line at an opposite end of a first rail car and a second rail car (not shown). A cavity 26 is formed in a second end of the female connection member 30. This cavity 26 receives therein at least a portion of each of the second end 14 of the male connection member 20 in the opening 16 formed through the portion of the second end 14 of the male connection member 20. This cavity 26 is formed by a substantially horizontally positioned lower wall portion 32, a substantially vertical rear wall portion 34 connected along a lower edge of the wall. the same to a lower edge of the lower wall portion 32 and a pair of vertically positioned side wall portions 36 connected along a lower edge thereof to the lower wall portion 32 and along a rear edge of the wall. the same to the rear wall portion 34.

A vertically placed plane, which intersects a central geometric line of each of the respective pairs of sidewall portions 36 is substantially parallel to each of these. An inner surface of each of the lower wall portion 32 and the rear wall portion 34 and the pair of side wall portions 36 define a predetermined size and a predetermined shape in the cavity 26 that opens adjacent to an upper surface and front of it. An opening 38 is formed through a predetermined portion of each of the pair of side wall portions 36. The articulated coupling arrangement 10 includes a connection assembly 40. Such a connection assembly 40 includes a substantially spherical member 42. The member of a one-piece raceway 45 is formed integrally with the spherical member 42 and encircles at least a portion of the spherical member 42. The outer surface 47 of the raceway member 45 has a configuration, which allows the spherical member 42 have the rolling ring member thereon to be positioned or fitted within the opening 16. In a preferred embodiment, the outer surface 47 of the one-piece rolling ring member 45 will come into contact with the inner surface 17 of the opening 16 formed in the male connection member 20. Any well-known technique and / or material can be used to integrally form the member d and a one-piece rolling ring with the spherical member as long as the resulting connection assembly has sufficient strength to withstand the forces generated by the one-way service and rotation of the spherical member against the rolling ring member. In a preferred embodiment, the one-piece rolling ring member 45 can be formed of a polymeric and / or composite material and formed integrally on the spherical member by means of a filament winding process. For example, the one-piece ring member 45 can be formed by placing the Teflon® / Dacron® wire mesh base around the spherical member 42 and winding a resin-impregnated reinforcement material, such as glass, into the filament. impregnated with epoxy around the base, curing the resin in the fibers, and machining the rolling ring member 45 to the desired size. Teflon®, also known as PTFE and / or polytetrafluoroethylene, and Dacron®, also known as polyester, are registered trademarks of E.l. Dupont De Nemours. The Dacron® yarns allow the resin-impregnated fibers to be bonded to the desired shape while the Teflon® yarns provide a non-stick surface, which will provide sufficient lubrication between the outer surface of the spherical member 42 and the inner surface 49 of the One-piece rolling ring member 45. This type of material has especially good strength and lubricating capabilities, which allow unrestricted movement of the spherical member against it. Other polymeric materials, well known in the art, may be used to form the one-piece ring member as long as such materials provide sufficient strength and lubrication to such a one-piece ring member 45. An agent may be provided. releasing or detachment on the surface of the spherical member 42, if desired, to prevent adhesion of the one-piece raceway member 45 to the surface of the spherical member 42. Also, a coating or lubricant material may be provided on the surface of the spherical member 42 before placing the one-piece rolling ring member 45 thereon. Any well known release agents and coating / lubricant material can be used. Securing means 43 is provided to secure the one-piece race ring member 45 within the opening 16 of the male connection member 20. These securing means 43 may be mechanical securing means., such as in the form of a circular ring 51 which is secured, such as by welding, along the interfacial surface area 53 of the inner surface 17 of the male connecting member 20 and the outer surface 47 of the running ring member One piece 45. Depending on the environment for which the running ring is being used, an adhesive material, brazed material, or any type of well-known securing material can be used to secure the one-piece ring member in its place. For example, in the railroad industry, securing material must be used, which can sufficiently resist the forces exerted on the coupling device during use in a railway vehicle to obtain a one-piece rolling ring member 45 which remains secured within of the opening 16 of the male connecting member 20. This securing material can be inserted between the outer surface 47 of the one-piece rolling ring member 45 and the inner surface 17 of the opening 16 of the male connecting member 20. A Further option, depending on the material used to form the rolling ring member in a part 45, would be that this one-piece rolling ring member 45 be welded or fused within the opening 16 of the male connecting member 20. In some Applications for a sphere and race ring assembly, may be desirable as an alternative technique to secure a member of a one-piece tread ring of the polymeric and / or composite type impregnated with thermosetting resin 45 within an opening would partially cure the thermosetting resin in the rolling ring member 45 during production. Then, during the assembly of the spherical member 42, having the one-piece ring member 45 integrally formed therein, within a connecting assembly, completely cure the resin, so that this resin is attached to the ring member of a piece 45 running inside the opening.

In the preferred embodiment hitherto of this invention, the second end 14 of the male connection member 20 has a predetermined configuration adjacent to an outermost end 18 thereof. This predetermined configuration of the outermost end 18 of the second end 14 of the male connection member 20 is substantially convex in each of a vertically placed plane and a horizontally placed plane. Further, it is preferred that the vertically positioned rear wall portion 34 of the cavity 26 formed in the second end of the female connection member 30 have a predetermined configuration of the vertically placed rear wall portion 34 of the cavity 26 is substantially concave in shape in at least one of a vertical plane and a horizontal plane. It is also preferred that the spherical member 42 and the pair of shaft members 46 form a portion of the connecting member 40 of the articulated coupling arrangement 10, formed as a single piece.
