Abstract
Improvements in material-to-material connections are provided. For example, metal-to-metal connections are improved, such as the interface connection between a dental handpiece bur tube (10) and a component such as a bearing (12). At least one marking, such as a laser marking (20) is provided such that an amount of excavate material (21) is excavated from the marking (20). When a component such as a bearing (12) is positioned upon the bur tube (10), a portion of the excavate material (21) is physically impinged between the two components (10, 12) filling any spaces or gaps therebetween.
Description
- This application is an ordinary application claiming the benefit from Provisional Application No. 60/256,303.
- The present invention generally relates to improvements in precision material-to-material, such as metal-to-metal, connections. More particularly, the invention relates to connections between two metal parts, wherein each part is sized so as to accommodate and facilitate the connection, such as the press-fit of a bearing upon a rotatable shaft. Specifically, the invention relates to laser or non-laser marking, scribing, cutting, or otherwise machining one of the parts to form a groove or other depression positioned proximate to a quantity of excavated material removed during formation of the groove or depression. The second part is then fitted to the first part such that the excavated material at least partially fills any gaps between the two parts.
- Precision fit between metal parts if often required in a number of industrial applications. For example, the fit between bearings or races and rotating shafts is often required to have high tolerances. In the case of a bur tube for a dental handpiece, a press fit is often used between for example, the bur tube (or shaft) and a bearing inner race. The outside diameter is desired to be greater than the inside diameter of the race to make the press-fit connection secure. Tolerances of 50 to 100 millionths of an inch is often required.
- It is the case with many such shaft connections, that an adhesive is often used between the shaft and the fitted component. While this may fill any gaps between the two metal parts, it is often not desired to use an adhesive in some applications. In the case of a dental handpiece, the area in which the adhesive is to be placed is often very small, making precise application of the adhesive difficult. Further, dental handpieces must be subjected to repeated sterilization procedures over their useful life, often under high temperature and pressure. Such environments will degrade many adhesives.
- It is also the case that with such close tolerance requirements, that a number of metal parts will be measured and sorted based upon size. The metal parts can then be matched to appropriately and correspondingly sized counterparts. This is a time consuming and expensive procedure at best.
- A need exists therefore, for an improvement in connections between metal parts. The improvement should meet the need of filling gaps between metal parts and otherwise facilitating connections, particularly press-fit type connections.
- It is therefore, an object of the present invention to provide metal-to-metal connections.
- It is another object of the invention to provide such connections between parts that are sized to accommodate and facilitate such connections.
- These and other objects of the invention, which will become apparent from the present discussion, are accomplished by the invention as hereinafter described and claimed.
- In general, a method of fitting together two metal parts having metal-to-metal physical contact between opposing surfaces thereon, comprises the steps of creating a groove, hole, perforation or other excavation in a first one of the parts, such that an amount of excavated material is removed from the excavation yet which remains adjacent and proximate to the excavation; and fitting the second one of the part to the first part such that an amount of the excavated material is positioned between the two parts when they are in their fitted together relation.
- FIG. 1 is a perspective view of a bur tube or shaft for a dental handpiece, having laser markings according to the present invention.
- FIG. 2 is a perspective, exploded view of the bur shaft of FIG. 1, also showing exemplary component parts used with a bur shaft assembly.
- FIG. 3 is a side, plan view of the assembled bur shaft assembly of FIG. 2.
- FIG. 4 is a close-up view of a portion of the bur shaft of FIG. 1, showing the laser marking in detail.
- FIG. 5 is a closer view as in FIG. 4, showing the laser marking and showing excavated material adjacent thereto.
- The present invention has application to the joining or connecting of two metal objects each having at least one surface in an opposed and physically contacting relationship the other such surface. The invention has particular application to the connection of such metal-to-metal parts wherein the size or contours of each part is selected so as to facilitate or make the connection. As an example, when a metal part is press-fit to another, as when a bearing is press fit to a shaft, the size of each component part is critical in determining the strength of the press-fit connection.
- It will also be appreciated that the present invention has application to the connecting of parts made from materials other than metal. One or both parts can be made of a polymeric, carbon or other material, as long as the appropriate excavate as will be discussed below, is obtainable. The invention has particular application to the joining of metal-to-metal surfaces, and will be exemplified herein as such, it being understood that “metal” will include all materials capable of forming an excavated material, even if they are not traditionally defined as metals.
- The present invention will also be exemplified herein with reference to a dental bur tube or
shaft 10 as shown on the drawings. Burtube 10 is of any conventional design. As is common in the dental handpiece art,bur tube 10 is included in a bur tube assembly 11 as is generally shown completed in FIG. 3, and in an exploded view in FIG. 2. Bur tube assembly 11 may include for example,lower bearing 12, upper bearing 13,turbine 14 andstop washer 15. - Components of bur tube assembly11 generally have an outer surface and an inner surface. For example,
lower bearing 12 has an outer surface 12 a and an inner surface 12 b. Inner surface 12 b will physically contactbur tube 10 when in the assembled position as shown in FIG. 3. - As discussed above, the dimensions of inner diameter of lower bearing12 and of
bur tube 10, are critical in determining the efficacy of the contact betweenbur tube 10 andlower bearing 12. If carefully machined or otherwise fabricated, the contact between the two parts can be a press-fit or a friction fit. With small dimensions as encountered in the dental handpiece art, and indeed with any such connections no matter what the size, careful sizing is difficult. There are often gaps between two such parts as lower bearing 12 andbur tube 10. It will also be appreciated that the present invention is useful with connections other than to correct imperfections. The present invention is useful for connecting materials such as metals, even when the same have been machined to very high and precise standards. - According to the present invention, at least one and preferably a plurality of laser or
non-laser markings 20 are made inbur tube 10.Markings 20 may be of any depth, size, shape or location, all such parameters varying according to the end use of the actual product. One useful marking 20 forbur tube 10, is a plurality oflinear laser markings 20 positioned axially onbur tube 10. By “laser marking” it is meant that an amount of the underlying material is grooved, gouged, displaced or otherwise excavated, in a manner such that an amount of material orexcavate 21 is removed from the excavation site, and is pushed or otherwise deposited adjacent or proximate to the excavation site, such as laser marking 20. It will be appreciated that laser marking may be accomplished in any otherwise conventional manner, by any conventional device, including by use of lasers, mechanical scribers or cutters, or the like. One useful laser device is available from GSI Lumonics, Model HM 1400 YAG. - It is believed that excavate21 that forms adjacent to laser marking 20 will be softer than the material of underlying structure from which it is removed, owing to the thermal or other effects induced by the action of the laser, cutter, scribe, electric discharge, or the like.
- It is to be appreciated that any means of excavating laser-marking20 is within the scope of the invention. For small precision parts such as
bur tube 10, a laser is preferred. However, any other device that will create marking 20 and excavate 21 is within the scope of the invention, including for example, electric discharge apparatuses (EDM), mechanical machining scribes, cutters and the like. For ease of this description, the excavations made by all such devices are within the scope of the term “laser marking” or “marking” as used herein, even if such devices are not traditionally within the scope of the definition of “laser.” - By being softer than the material from which it is formed, excavate21 is more pliable than the metal of the underlying structure. As such, when another surface is brought into contact with
excavate 21, excavate 21 may be deformed thereby. For example, whenlower bearing 12 is press-fit intobur tube 10, excavate 21 will be deformed therebetween, filling any gaps betweenlower bearing 12 andbur tube 10. Of course,such excavate 21 is useful for filling gaps between any structures, such asupper bearing 13,turbine 14 and stopwasher 15. It is also to be appreciated that becauseexcavate 21 is softer than the metal from which it is originally removed, the interior surface 12 b oflower bearing 12 will not be deformed by its physical interaction withexcavate 21. - As an example, with
bur tube 10, the present invention will improve the press fit connection between all components of the spinning dental handpiece turbine/rotor assembly. It will not deform the internal surface of a bearing's inner race 12 b andturbine 14 as current press fit technology, and therefore reduces noise and increase life of the handpiece product. - More specifically, bur tube assembly11 has axial laser marking passes 20 on the outside surface of the
bur tube 10. It provides exposure ofbur tube 10 material above the normal grind surface. Therefore, this increases the outside diameter (OD) ofbur tube 10 to a size larger than the lower bearing 12 (orupper bearing 13,turbine 14, and the like) inside diameter (ID). This created interference provides necessary press fit condition betweenbur tube 10 and other components, such asbearings turbine 14. - As stated above, any material that will form excavate21 is within the scope of the invention, whether it is a metal or otherwise. One preferred material is stainless steel from which dental bur tubes, such as
bur tube 10 are conventionally fabricated. - Therefore, according to the present invention, press fit conditions for bearings and turbines can be achieved without any additional machining, force measurement and selectivity of components. The invention will also provide secure positioning and required performance for all set assembly components.
- It is evident therefore, that the objects of joinery are carried out by the invention as herein described. All possible aspects of the invention beyond the best mode have not been necessarily described, and the scope of the invention shall only be determined by the following claims.
