Description

FIELD OF EXPERTISE

[0001] The present application relates generally to elongated, beveled coil springs and, more particularly, to methods, apparatus and systems relating to elongated, beveled coil spring contacts to facilitate their assembly. GENERAL STATE OF THE ART

[0002] Canted coil springs can be used, among other things, to achieve consistent contact between components. Due to the deflecting, or canted, properties of canted coil springs, reliable contact with a nearly constant contact force can be maintained between adjacent components and surface asperities within tolerances. A canted coil spring can be wrapped around an object, such as a piston or rectangular component, placed in housing grooves, or connected to components to enable mechanical or electrical contact with other components. When viewed in cross-section, a length of the spring on one side of the object has coils that are canted in an opposite direction compared to the coils on the other side of the object.When the object is inserted along the length of the spring into a receiving object such that longitudinal spring contact is established between the coils and the receiving object, the opposing skew of the coils can thereby create interference and / or resistance that may make insertion impossible or result in a greater force being exerted on the coils along one side of the object compared to the opposite side. Accordingly, insertion can prove difficult and awkward and / or misalignment can occur due to the uneven forces acting on the spring, which can cause twisting or rotating within the objects. An exemplary conventional skew coil spring wrapped around an object and used for longitudinal spring contact with push insertion is shown in . Fig. 8A and Fig. 8B of patent application publication US 2009 / 0 160 139 A1, the contents of which are expressly incorporated herein by reference for all purposes.

[0023] The following detailed description, in combination with the accompanying drawings, serves as a description of embodiments of a canted coil spring, a canted coil spring system, and methods of manufacture, and is not intended to set forth the only forms in which the present assemblies and methods may be constructed or used. The description, in conjunction with the illustrated embodiments, sets forth the features and steps for using and manufacturing the canted coil springs, the canted coil spring system, and the methods. It should be understood, however, that the same or equivalent functions and structures may be achieved by other embodiments, which are also intended to be included within the spirit and scope of the assemblies and methods. As noted elsewhere herein, like element numerals indicate like or similar elements or features.

[0024] Fig. 1 shows a canted coil spring 30 according to an exemplary embodiment. The canted coil spring 30 includes a first portion 32 having a plurality of turns 34 and a second portion 36 having a plurality of turns 38. A centerline C extends through the turns 34 of the first portion 32 and the turns 38 of the second portion 36. The turns 34 of the first portion 32 are canted at a first acute angle α1 relative to a direction CR of the centerline C. The turns 38 of the second portion 36 are canted at a second acute angle α2 relative to a direction CL, opposite to the direction CR, of the centerline C. Accordingly, the turns 34 of the first portion 32 are canted in the direction CR, while the turns 38 of the second portion 36 are canted in the direction CL.Accordingly, the windings 34 and 38 are beveled in opposite directions. The angles α1 and α2 can be the same or different. In the embodiment of . Fig. In Figure 1, the angles α1 and α2 are shown as equal. The first section 32 and the second section 36 are connected by a transition region 40.

[0025] With reference to Fig. 2 and Fig. 3, when the beveled coil spring 30 is wound around an object 50, which may be a shaft, referred to herein as shaft 50, the coils 34 and 38 are generally beveled in the same direction since the directions CR and CL of the centerline C are no longer opposite to each other. With reference to Fig. 4 and Fig. 5, when the shaft 50 is inserted in an insertion direction ED into another object 52, which may be a housing for receiving the shaft 50, referred to here as housing 52, a sliding contact, referred to here as longitudinal sliding contact, occurs along the length of the spring 30 with the inner walls 54 of the housing 52. As in Fig. As shown in Figure 5, the coils 34 of the first portion 32 and the coils 38 of the second portion 36 are beveled opposite to the insertion direction ED of the object 50. Since the angles α1 and α2 of the spring 30 are equal in this embodiment, the longitudinal sliding contact between the first portion 32 and the associated inner wall 54 of the housing 52 generates a resistance that is in the same direction as, and similar to, the resistance generated by the longitudinal sliding contact between the second portion 34 and the associated inner wall 54 of the housing 52. Since the first portion 32 and the second portion 36 are opposite relative to the insertion direction ED or a removal direction RD, any misalignment and / or twisting of the shaft 50 that may occur during insertion into the housing 52 or removal of the shaft 50 from the housing 52 is reduced.Furthermore, because the coils 34 and 38 are tapered away from the insertion direction ED and toward the withdrawal direction RD, less resistance is encountered when inserting the shaft 50 into the housing 52 than when removing the shaft 50 from the housing 52. As a result, the effort or force required to insert the shaft 50 into the housing 52 is less than the effort or force required to remove the shaft 50 from the housing 52, which may be a preferred feature for certain applications of the spring 30. As can be seen from the above, the reduced insertion force compared to the withdrawal force is achieved by having the coils of the spring on both sides of the shaft tapered in the same direction.

[0026] Again with reference to the exemplary Fig. In the embodiment of the spring 30 shown in Figure 1, the transition region 40 includes a straight wire that forms a continuous, one-piece portion with the first section 32 and the second section 36. Accordingly, the first section 32, the transition region 40, and the second section 36 are formed in one piece from the same wire. The straight wire in the transition region 40 can be used in applications where no spring force is desired along a particular portion of the spring. Furthermore, as shown in Fig. 2, the straight wire allows spring 30 to be wrapped around shaft 50 such that the straight wire is positioned at one end of shaft 50 where either there is no contact with housing 52 or spring force is not desired. However, those skilled in the art will readily appreciate that transition region 40 can be configured in any shape, size, and material(s) to provide a particular function to spring 30. For example, transition region 40 can be configured as minimally as possible so that an end turn 34 of first section 32 directly communicates with an end turn 38 of second section 36. Transition region 40 can be a canted coil spring having different characteristics than first section 32 and / or second section 36.Furthermore, the transition region 40 may be a conventional spring, another type of elastic structure, such as an elastomer component, or any other structure having any shape, size, and / or material(s) that can provide a preferred function. The transition region 40 may also be formed separately and subsequently joined to the two spring sections 32, 36.

[0027] With further reference to Fig. 1 and Fig. 6, in an exemplary embodiment, when the spring 30 is wrapped around the shaft 50, the ends 39R and 39L of the spring 30 may be connected to secure and / or retain the spring 30 on the shaft 50. The ends 39R and 39L may be connected by devices and methods known to those skilled in the art. For example, the ends 39R and 39L of the spring 30 may be welded together, which is Fig. 6 by a weld 56. The ends 39R and 39L may also be connected by fasteners or similar devices (not shown) so that the ends can be separated and reconnected as needed. In other embodiments, the spring 30 is mounted within the housing rather than on the shaft, with at least two different portions of the spring located on two different sides of an axis tapered in the same direction.

[0028] With reference to Fig. 7 and Fig. 8, a spring 60 according to another exemplary embodiment includes a first portion 62 having coils 64 and at least one second portion 66 having coils 68. The first portion 62 and the second portion 66 are separate tapered coil springs that are connected by welding at the transition region 40, as represented by a weld seam 70a. However, the first portion 62 and the second portion 66 may be connected by any method other than welding, such as by a fastener or connecting means. Referring to Fig. 8, when the spring 70 is wound around the shaft 50, the ends 69R and 69L of the spring 70 may be connected to secure and / or retain the spring 30 on the shaft 50. The ends 69R and 69L may be connected by devices and methods known to those skilled in the art. For example, the ends 69R and 69L of the spring 70 may be welded together, which in Fig. 8 by a weld 70b. The ends 69R and 69L may also be connected together by fasteners or similar devices (not shown) to allow the ends to be separated if necessary.

[0029] In a Fig. 9 and Fig. 10, a spring 100 having a first portion 102 with coils 104 and a second portion 106 with coils 108 is received in grooves 111 of a shaft 110. Similar to the spring 30 of Fig. 1, the coils 104 and 108 are generally tapered in the same direction when arranged around a shaft 110, as shown. For connection to a housing 112, the shaft 110 may be inserted into the housing 112, with the spring and coils 104 and 108 making longitudinal sliding contact with the housing 112. The grooves 111 may align or assist in the alignment of the spring 100 with the insertion direction ED and the withdrawal direction RD. Due to the grooves 111, the first portion 102 may be connected to the second portion 106 only at the transition region 40. Accordingly, the end 109R of the first portion 102 and the end 109L of the second portion 106 may not be connected. Further, each groove 111 may be independent and have closed ends.Accordingly, the first portion 102 and the second portion 106 may not be connected at all and may be separate, since any movement of the portions 102 and 104 is restricted within their respective grooves 111. For example, the grooves may be dovetail-shaped to retain the two spring portions within their respective grooves. Although the grooves 111 are illustrated and described herein as being disposed within the shaft 110, the grooves 111 may alternatively be disposed within the housing 112. In another embodiment, both the shaft 110 and the housing 112 may include grooves, with each groove receiving at least a portion of the spring 100. In . Fig. 10, the grooves 111 are shown with generally straight or parallel side walls and with inclined or sloping bottoms between the side walls. However, the grooves 111 may have any shape in cross-section to provide a preferred function of the spring 100. For example, the grooves 111 may be shown with reference to Fig. 11 and Fig. 12 in cross-section a dovetail shape (in Fig. 12) to retain the tongue in the groove after the tongue 100 has been secured in the grooves 111. In other embodiments, the groove has a flat bottom.

[0030] In a Fig. 13-15, a spring 120 having a first portion 122 with coils 124 and a second portion 126 with coils 128 is wound around a shaft 130 in a configuration inclined relative to the shaft axis SX. The insertion direction ED of the shaft 130 is at an angle relative to the interior walls 134 of the housing 132. In other words, the insertion direction ED is oriented at a skew angle θ relative to the central axis HX of the housing 132. By aligning the grooves 131 at the same angle θ relative to the shaft axis SX, the spring 120, and hence also the coils 124 and 128 of the first portion and the second portion 122 and 126, respectively, are longitudinally aligned with the insertion direction ED.

[0031] In a Fig. In the exemplary embodiment illustrated in Figure 16, a spring 140 includes four sections 142a, 142b, 146a, and 146b. The spring 140 is wound around a shaft 150 having a square cross-section that can be inserted into a housing (not shown) in two different insertion and removal directions ED1, RD1 and ED2, RD2. Accordingly, when the spring 140 is unwound from the shaft 150 and aligned linearly, the coils 144a of section 142a and the coils 148a of section 146a are tapered opposite to each other, and the coils 144b of section 142b and the coils 148b of section 146b are tapered opposite to each other. Thus, when the spring 140 is wound around the shaft 150, the coils 144a and 148a are beveled in the same direction and the coils 144b and 148b are beveled in the same direction. Although the shaft 150 is Fig. 16 as having a rectangular or square cross-section, the shaft may have any desired shape, such as oval, hexagonal, rounded rectangular, or any other geometric shape. Accordingly, a spring according to the disclosure may be manufactured with any number of sections for use with such a shaft. Those skilled in the art will readily appreciate from the above exemplary embodiments that the spring 140 may have any desired number of segments, with the coils in each segment being tapered in the opposite or same direction as adjacent or other segments in the spring to provide a preferred function for the spring or to enable use of the spring in combination with an object of any desired shape or size.

[0032] With reference to Fig. 17-19b, numerous exemplary grooves 179 are shown in a shaft 170 for receiving a beveled coil spring 160 according to the exemplary embodiments. In Fig. 17, the shaft 170 is hooked into a recess of a housing 172 by a beveled coil spring 160 according to an exemplary embodiment. The shaft 170 has a flange 174 that abuts the housing 172 upon insertion to control the depth of insertion into the housing. In Fig. 18a, the beveled spiral spring 170 is arranged in a square groove with a groove width that is wider than the main axis of the spring. The spring may be a radial spring. In Fig. 18b, the tapered coil spring 160 is arranged in a groove with a tapered bottom. The groove has a groove width that is smaller than the main axis of the spring. The spring can be an axial tapered coil spring or a radial tapered coil spring. Fig. 19a, the groove 179 has a V-shaped bottom, while the groove in Fig. 19b has a sloping or tapered bottom. In addition, Fig. 19a and Fig. 19b The housing grooves are shown. Accordingly, the Fig. 19a and Fig. 19b are formed in both the shaft and the housing. These grooves are Fig. 19a and Fig. The grooves shown in Figure 19b are preferably used for hooking or locking applications.

[0033] With reference to Fig. 20 and Fig. 21, a shaft 190 having a rectangular or square cross-section is shown with a groove 189 extending in a V-shaped arrangement around the shaft 190 and configured to receive a spring 180 according to an exemplary embodiment. The V-shaped arrangement of the groove 189 reduces the contact angle between the inner surface 194 of the housing 192 and the coils 184 and 188 of the spring 180 during insertion of the shaft 190 into the housing 192 and increases the contact angle between the inner surface 194 and the coils 184 and 188 during removal of the object 190. Accordingly, the object of Fig. 20-21 requires a smaller force for insertion into the housing 192 and a larger force for removal from the housing 192 than would be the case for an object with a radial groove using the same spring as spring 180.

[0034] At this point, exemplary methods for manufacturing a chamfered coil spring are described with reference to Fig. 1 and Fig. 7. A beveled spiral spring, such as the exemplary spring 30 from Fig. 1, may be manufactured by methods known to those skilled in the art, except that the turns 34 of the first section 32 and the turns 38 of the second section 36 are manufactured to have turn angles that are tapered in opposite directions. The transition region 40 may be manufactured to have any shape or length to provide a preferred function. In the exemplary embodiment of Fig. 1, the transition region 40 includes a straight wire. According to another Fig. 7, the first section 62 and the second section 66 are manufactured separately and then joined together by welding or other methods to form the spring 60. Based on the above description, it will be readily apparent to those skilled in the art that a canted coil spring having a plurality of sections, as shown in the exemplary embodiment of Fig. 16, which has coils with different skew angles, can be manufactured as a one-piece, continuous spring with a plurality of sections or as spring sections that are manufactured separately and subsequently joined.

[0035] Although limiting embodiments of canted coil springs, canted coil spring systems, and methods of manufacturing the canted coil springs are described and illustrated herein, numerous modifications and variations will be apparent to those skilled in the art. Accordingly, it is understood that the canted coil springs, canted coil spring systems, and methods of manufacturing these springs according to the principles described herein may be embodied differently from the specific descriptions contained herein. The canted coil springs, canted coil spring systems, and methods of manufacturing these springs are further defined in the following claims.
