Definitions

  • the present invention relates to linear guides having a slide body and a guide rail. More specifically, the present invention relates to a linear guide in which the slide body, the guide rail, or both are unitarily constructed of polymer, coated, or otherwise provided with a polymer bearing surface.
  • Linear motion guides are an important component in the construction of automated and other equipment.
  • the linear motion guide (hereinafter just “linear guide”) provides for high precision as a piece of equipment, such as a robotic arm or workpiece, is linearly moved back and forth over a relatively long distance. Since each linear guide has only a single degree of freedom, longitudinally along its guide rail, multiple linear guides may be used in combination to provide additional degrees of freedom for the moving of the equipment.
  • linear guides have two primary components, a guide rail (also known as a track and hereinafter referred to as a “rail”) and slide body (hereinafter just referred to as a “slider”).
  • the slider and rail are designed so that the slider mounts and moves along the rail without play or backlash. This is achieved by employing a bearing mechanism between the two.
  • recirculating ball bearings are captured within the slider and contact a bearing race formed in the rail.
  • Such systems are relatively costly to produce and replace.
  • the construction of the recirculating ball bearing slider is such that, at a minimum, the entire slider must be replaced and, more typically, both the slider and rail. It is not feasible to merely replace the ball bearings because of the wear in the raceways where the bearings contact the slider and the rail.
  • linear guide actually eliminates the use of recirculated ball bearings while still providing the necessary low sliding friction between the slider and the rail.
  • a bearing material is permanently bonded to the slider so as to provide a contact interface between the slider and the rail.
  • Polymer materials used to form these bearing surfaces have included nylon, polytetrafluorethylene (PTFE) and numerous others.
  • PTFE polytetrafluorethylene
  • Another object of the present invention is to provide a linear guide which eliminates the need for separately manufacturing the slider and the bearing.
  • a further object of the present invention is to provide a linear guide in which the bearing element and the slider or rail are formed as a unitary component.
  • a linear guide as with prior linear guides which includes a slider that is slidably mounted to a guide rail.
  • the slider and in alternate embodiments the rail, defines the bearing surface which allows the slider and rail to move relative to each other.
  • the slider of the present invention includes a body having a top, a bottom, opposing sides and opposing ends. Portions of the body define a channel that extends longitudinally through the length of the body, between the opposed ends.
  • the channel has an open side generally in the direction of the bottom of the body and exhibits a cross-sectional shape which allows the rail to be received therein.
  • the rail has opposing ends that define its length, which is greater than the length of the body.
  • the interaction between the cross-sectional shape of the body and the rail is of a low clearance and allows for movement of the body along the rail restricting movement to a single degree of freedom. Lateral or vertical movement of the body relative to the rail is accordingly inhibited.
  • the slider or rail is made from one of several preferred polymeric materials having a low coefficient of friction, high load capacity and good wear characteristics which facilitates the longitudinal sliding movement of the slider relative to the rail.
  • the present invention encompasses embodiments where the slider is composed of polymer and the rail is a non- polymeric material, where the rail is composed of polymer and the slider is a non-polymeric material, where both the rail and slider are composed of polymer, where the rail has polymer bonded to a non-polymeric core, and where the rail includes replaceable polymer bearing inserts. In embodiments where both the rail and slider are made of polymeric materials, it is preferable that they be made from different polymeric materials.
  • FIG. 1 is a perspective view of a linear guide embodying the principles of the present invention
  • FIG. 2 is an exploded view of a linear guide according to the principles of the present invention
  • FIG. 3 is a sectional view taken substantially along line 3-3 in FIG. 1 illustrating various features of the present invention
  • FIGS. 4-7 are a sectional views taken substantially along line 3-3 in FIG. 1 of alternate embodiments of the present invention.
  • FIGS. 8a-8b are alternate views of an alignment mechanism for the slider of the present invention.
  • FIG. 1 a linear guide, generally designated at 10, embodying the principles of the present invention.
  • the linear guide 10 principally includes a guide rail ("rail 12") on which is supported a slide body ("slider 14").
  • the rail 12 or slider 14 may be constructed out of aluminum, steel, polymer or other suitable material.
  • the rail 12 is a longitudinal member and includes a top surface 16, a bottom surface 18, and opposing side surfaces 20.
  • Vertical bores 22 are provided in the rail 12, extending from the top surface 16 to the bottom surface 18, to enable the securing of the rail 12 to a suitable base or table by fasteners such as screws (not shown).
  • the bores 22 are provided in a manner which will allow the heads of the fasteners to be counter sunk beneath the top surface 16. In this way, the fasteners will not interfere with movement of the slider 14 along the guide rail 12.
  • the side surfaces or sides 20 of the rail 12 are profiled such that inclusions 24 are directed generally toward one another inwardly of the rail 12.
  • the inclusions 24 are provided in the shape of trapezoidal indentations into the sides 20. As further discussed below, the inclusions 24 cooperate with protruding portions of the slider 14 to retain the slider 14 on the rail 12 and limit relative movement between the two to an axial or longitudinal direction along the rail 12.
  • the slider 14 is a generally rectangular body which includes a top surface 26, a bottom surface 28, opposed side surfaces 30 and opposed end surfaces 32.
  • the top surface 26 forms a generally planar surface to which at least a portion of the component to be guided by the linear guide 10 is mounted.
  • mounting bores 34 are vertically provided in the top surface 26 and into the slider 14. Bolts or other fasteners (not shown) can be extended through the slider 14 and through the mounting bores 34 allowing a nut or other engagement mechanism (not shown) to engage the opposing end of the fastener.
  • the bores 34 may be threaded or provided with threaded inserts (molded or otherwise formed therein) to engage the fastener, without further engagement with the nuts.
  • Cut-outs 36 are formed in the slider 14 to recess the nuts (if utilized) within the exterior dimensions of the slider 14.
  • the cut-outs 36 are illustrated as extending upward from the bottom surface 28 and inward from the side surfaces 30 and end surfaces 32 to locate the cut-outs 36 generally in the four corners of the slider 14. Obviously, alternative locations and configurations, or even complete elimination thereof of the cut-outs 36 could be employed depending on the specific design criteria of the linear guide 10 and its intended application.
  • a channel 38 Formed longitudinally through the slider 14 and generally being open in the direction of the bottom surface 28, is a channel 38 whose cross-sectional shape generally corresponds to the cross-sectional shape of the rail 12. As seen in FIG. 3, the cross-sectional shape of the channel 38 is closely dimensioned to conform to the cross-sectional shape of the rail 12. Adjacent to the bottom surface 28, the protrusions 40 define a necked-down entrance area into the channel 38 and this cooperates with the channel to inhibit vertical and lateral movement of the slider 14 relative to the rail 12.
  • the slider 14 rests directly on the rail 12 and its channel 38 defining surfaces function and operate as a bearing element.
  • the surfaces defining the channel 38 can include a series of protuberances or raised sections not shown, extending partially or fully along the length of the channel 38, which engage the rail 12 and operate as a bearing surface of the slider 14.
  • the slider 14 in the preferred embodiment utilizes a self alignment mechanism 47 which includes spring biased plungers 48, as seen in FIGS. 8a and 8b.
  • the plungers 48 provide for self alignment of the slider 14 relative to the rail 12.
  • a plurality of bores 46 extend laterally through slider 14 so that the plungers 48 (three in the illustrated embodiment) contact the rail 12 at an upper vertical face 49 thereof.
  • the bores 46 are equidistantly located along the length of the slider 14 for equalizing the loading and self alignment of the slider 14 relative to the rail 12.
  • the contact between the plungers 48 and the rail 12 is adjustably provided by the incorporation of coil springs 50 or other biasing mechanism /member between the plunger 48 and a set screw 52 which is threadably received in the bore 46.
  • the force exerted by the plungers 48 on the rails 12 is varied by progressively advancing or retracting the set screws 52.
  • This change in position varies the force exerted by the plungers 48 upon the rail 12 and allows the position of the slider 14 to self-align relative to the rail 12.
  • three plungers 48 are used to self-align said slider 14 with said rail 12, although a greater or lesser number could be used.
  • the plungers 48 are themselves made of a low friction polymeric material, such as one of the materials described below, since they too contact and slide along the rail 12.
  • the plungers 48 are retained in threaded casings that are threaded into the bores 46.
  • a spring that biases the plunger such that the plunger partially protrudes from a necked down portion of the casing.
  • the opposite end of the casing is closed to retain the spring and include a drive socket or head allowing it to be advanced or retracted in the bore 46.
  • the force is exerted by the plungers 48. While the plungers 48 may directly contact the rail 12, they also may all contact a common gib which is itself in contact with the rail 12.
  • the gib is supported by the body 14 or may extend approximately the length of the body 14. As such, the gib may be received in an axial slot formed in the body 14 and is mounted with respect thereto for a limited amount of transverse movement, for example 0.001 inches. Since it contacts the rail 12, the gib is made of a low friction polymer and, in this embodiment, the plunger 48 may be of a different material, such as steel.
  • the polymer material may be cast or otherwise molded into the desired end shape, may be extruded into the desired end shape, or may be initially formed in any manner and then machined into the desired shape.
  • the bores 34 and 46 mentioned above are machined or molded into the slider 14. If the bores 34 and 46 are threaded, the internal threads are either tapered into a machined bore or internally threaded inserts (of metal or other suitable material), known as heli-coils, are molded in place within the body of the slider 14 or mounted into the bores 34.
  • the basic operating limits for a linear guide 10 according to the present invention are anticipated to be: load (300-750 Ibs./slide body); pressure/velocity level (approximately 7500); and maximum operating temperature (300-500° F) up.
  • load 300-750 Ibs./slide body
  • pressure/velocity level approximately 7500
  • maximum operating temperature 300-500° F up.
  • operating parameters beyond the above listed parameters could be employed upon appropriate design considerations being employed.
  • the load capacity of the linear guide 10 might be increased by the inclusion of reinforcement members (such as rods, mesh, grids or other structures) within the body of the slider 14 during initial formation.
  • the material from which the slider 14 is formed needs to have a low coefficient of friction, good wear capabilities and not necessarily require wet lubricants. Any suitable material which meets the above criteria therefore constitutes a preferred material of this invention.
  • thermosetting polymers such as epoxy resins, allyl esters, amino polymers, phenolics, polyesters, polyamides and nylons, cyanoacrylates, polyurethanes, silicones and mixtures thereof; thermoplastic polymers such as polystyrene, polyethylene, polyvinyl chloride, polyethylene terapthalate, and mixtures thereof; materials with characteristics of both of the above varieties of polymers; and plastic lubricants such as polytetrafluroethylene (PTFE) and filled PTFE.
  • the polymer could also include known self or solid lubricating components.
  • an acceptable polymer will be any polymer capable of carrying an adequate load while maintaining low friction characteristics.
  • One specific preferred polymer material having a PV of 7500, an operating temperature range of over 300° F, is an extruded polyamide-imide commercially available from the DSM Polymer Corporation, Reading, Pennsylvania under the tradename of TORLON.
  • the coefficient friction of this material is 0.20, the operating temperature range of this material is over 500° F (making the material much stronger at elevated temperatures), the thermal expansion rate of the material is significantly low (allowing for closer tolerances between the parts) and the PV limit (45,000) greatly exceeds the anticipated requirements for most known applications of linear guides 10.

  • Such coatings are advantageous because of their wearability, low friction, anticorrosion and non-sticking characteristics.
  • Such coatings are well known and involve the conversion of the base metal surface into an oxide (ceramic) surface and the disposition or infusion of a polymer (such as a fluropolymer) into the oxide surface resulting in a new surface with superior performance characteristics.
