DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to bearings, and more particularly to a cross-roll type bearing. [Prior Art] According to the cross-roller bearing, the roller bearings are interlaced between the inner ring and the outer ring, so that the cross-rolling bearing can simultaneously bear radial load and axial load. And torque load. Compared to the bearing, the cross roller bearing is particularly suitable for applications requiring high rigidity and precision, such as tool machinery and robotic arm... Review the existing cross-roller bearings such as the special opening 2000_65080, special opening 2〇〇〇·ΐ7〇754, special opening 2002-13540 and special opening 2005_180578. The mounting holes for the roller are designed to be rolled with the track. In order to be vertical, this will cause the two bearings to have two obstructed faces and be damaged due to the installation hole arrangement. It also causes the bearing load capacity to be damaged compared to only one obstruction surface. In addition, the filler used to fill the mounting holes is ideal. In this case, the rail surface should be kept flat with the rail = equal. However, because of the addition of the difference, there will still be unevenness in the = and the obedient side. From the point of view of the conventional bearing, the filler must have a design that complements the two track faces. The volume = filler has been aligned with the obstruction surface of one of the orders, and the other is flat. Opportunity for uneven surface U-mouse bearing filler 1 is to be machined with V-groove composite double-sided to match the track surface, and its processing cost is higher than that of making a single curved surface. 201239216 [Summary content]. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a cross-roller auxiliary bearing which only produces breakage of the track surface, and its load capacity is higher than that of the prior art. The second aspect of the present invention is to provide a cross-roller bearing, which has a lower manufacturing cost and a lower chance of financial irregularity. In order to achieve the foregoing object, a t-fork roller bearing according to the present invention includes an inner ring having a first toroidal surface, and the inner ring forms a first surface on the first toroidal surface. a first rolling groove, the first rolling groove has a -: a first track surface and a second road surface; the outer ring is sleeved on the underwear, and the second ring surface and the wire hole are The ring forms a second rolling groove on the second annular surface, the second rolling groove is disposed corresponding to the first rolling groove; the second rolling groove has a third track surface and a fourth track surface and An obstructing surface and the second track surface together form an accommodating space; the mounting hole is continuous to the third or fourth track surface, and only the third track surface or the fourth road surface Forming a damaged portion while maintaining the contact area of the other track surface and the roller intact without damage; the plurality of rollers 'receiving respectively in the accommodating space; and a filling member disposed in the mounting hole and Fill the breakage. It is described that only the third or superficial orbital surface of the structural towel can produce a broken-to-track surface, which is higher than that of the conventional cross-rolling bearing. Moreover, the filling member only needs to form a single curved surface to fill the damaged portion and maintain the flatness of the third raceway surface or the fourth raceway surface, and the processing cost of the single-curved surface is compared with the conventionally formed v-groove composite The hyperboloids are low and have a high yield. 4 201239216 Furthermore, in the same spirit, the invention also provides a cross-roller bearing comprising an inner ring having a first annular surface and a mounting hole, the inner ring forming a first annular surface a first rolling groove, the first rolling groove has a first obligating surface and a second track surface; the mounting hole is through the first track surface or the second track surface, and only the first road surface Or the second track surface forms a breakage portion ' while maintaining the contact area of the other track surface and the roller intact without damage; an outer ring ' is sleeved outside the inner ring, and the outer ring has a second ring a second rolling groove formed on the second annular surface, the second rolling groove is disposed corresponding to the first rolling groove, and the second rolling groove has a complete third obstruction surface and a fourth Forming a receiving space, and forming a receiving space together with the first obeying surface and the second obligating surface; the plurality of rollers are respectively accommodated in the receiving space; and a filling member is disposed in the mounting Fill the hole with the damage. In the above structure, only the first raceway surface or the second raceway surface is damaged, and only one raceway surface is broken. Moreover, the filling member only needs to form an early curved surface to maintain the flatness of the first or second track surface after filling the damaged portion. [Embodiment] In order to explain the technical features of the present invention in detail, the following preferred embodiments are described below with reference to the drawings, wherein: the first preferred embodiment of the present invention is as shown in the first to third embodiments. A cross roller bearing provided by the embodiment mainly comprises an inner ring u, an outer ring 12, a plurality of rollers 13 and a filling member 4. 201239216 [Underwear 11 has a first toroidal surface 111, and the inner ring 11 is formed into a first rolling groove 112 at the first etching surface 111. The first rolling groove 1J2 has a complete shape. The first track surface U3 and the second road surface: 114. § 亥 ^ 衣 12, which is sleeved outside the inner ring 11, the outer ring 12 has a second ring surface 191 4: an upper-and-mounting hole 122 is formed on the second ring surface 121 a first rolling groove 123, the second rolling groove 123 corresponds to the first rich portion 112, and the second rolling groove 123 is again shaped, and the second rolling groove 123 has a shape and has a fourth. The surface 125' and the first obstruction surface 113 i2^, > r obstruction surface 114 together form an accommodation space 15. The mounting hole '糸 penetrates the third track surface 124 or the fourth track surface 125, and only a breakage 1' is formed by the § hai: r, da da, face 124 or the fourth track surface 125 Maintaining the other (in other words, the contact area of the orbital surface and the roller is intact without the damage surface being one-t. If the damage is located on the third obstruction surface, then the fourth orbit is the third (four) If the damage is located on the fourth road surface, then: 丨m / road surface is a complete track surface.), in this embodiment, the installation (3). (4) The "completeness" of the section of the section of the division of the division, and the "completeness" of the head and tail of the damaged section, which means that the orbital surface forms a single ring and a 7° whole ring' The contact area with the roller remains 1 Γ loss. The obstructed surface refers to the surface on which the roller (four) mesh can effectively contact each other and the column can roll on it. Therefore, the obstruction surface extends to both sides to the area where the original and the roller are in effective contact with each other. That is, the area that does not effectively contact the rollers is naturally not the obligatory surface, and the area (non-orbital surface) that would otherwise not be in effective contact with the roller is 201239216 intact and not damaged, and the present invention The claim has nothing to do. The provision of oil holes or other damage in areas that would otherwise not be in effective contact with the rollers does not prevent the integrity of the track surface, nor whether the road surface is not damaged. Each of the rollers 13 is respectively received in the accommodating space 15, and the filling member 14 is disposed in the mounting hole 122 and fills the damaged portion 126. In this figure, it is filled, but whether it needs to be filled to be completely flat is irrelevant to the claim of the present invention. For example, in the fourth embodiment, in addition to the fact that the filling member 14 fills the damaged portion 126 as an example, the damaged portion 126 may be filled with a chamfered end. It is to be noted that, in the preferred embodiment, the cross section of the first rolling slot 112 and the second rolling slot 123 are both in a "V" shape, which causes the section of the receiving space 15 to be 4 Quadrilateral, which fits the rim of the roller. The above is a description of the first preferred embodiment of the present invention, and the mode of operation of the first preferred embodiment will be described. Each of the rollers 13 is sequentially inserted into the accommodating space 15 from the mounting hole 122 in a staggered manner, and then the filling member 14 is disposed in the mounting hole 122 and fills the damage 126, so that The breakage 126 on the fourth track surface 125 obtains a fill of the filler member 14 and assumes a flat state. When the reciprocating roller bearing provided by the present invention is subjected to the load applied to the inner ring 11 by the outer ring 12, each of the rollers 13 will receive the second raceway from the second rolling groove 123. And an external force applied by the fourth obstruction surface 125, and then the external force is transmitted to the first rolling groove ι2 and the inner ring 11 through the first track surface 113 and the second road surface 114, so that the external force The ring 12 and the inner ring n can still smoothly rotate relative to each other under load. 201239216 Please refer to the fifth embodiment, which is different from the first preferred embodiment in that: in order to limit the degree of freedom of the filler member 14 in the direction of the accommodating space is, the preferred embodiment The towel ring 12 protrudes from the hole of the mounting hole f - the bearing surface 127. The filler member 14 is formed by a bearing surface 127 which is formed by the bearing portion 141 against which the bearing portion 141 abuts. This will limit the movement of the filler member 14 in the direction of the accommodating space ’ to the level of the fourth track surface 125 at the breakage. Referring to the sixth figure, a third preferred embodiment of the present invention differs from the second preferred embodiment in that the outer ring 12 has a positioning hole 127 for maintaining the position of the filling member 14, and the mounting thereof The hole 122 is in communication; the filling member 4 has a through hole 142 which is disposed corresponding to the positioning hole 127. A positioning pin 16 is threaded through the positioning hole 127 and the through hole 142. In the preferred embodiment, the retaining pin 16 is inserted into the through hole 1C to clamp the filler member to ensure that the filler member 14 is restricted from moving. π refers to the seventh to eighth figures' fourth preferred embodiment of the present invention. In fact, in the first preferred embodiment, the ampoule 122 has a circular cross section or ^ > When the wearing hole 122 of the women's hole is round, it is necessary to cooperate with a jig to assemble the various columns 13 into the space of the accommodating space. In the present embodiment, the jig 17 is a cylinder, and the inside thereof has a 171 ′ section having a quad-f-shaped cross section. Each of the corps 13 is filled with a fresh space 15 as shown in the ninth figure. It is worth mentioning that in order to reduce the raft and the frictional resistance generated by the collision of the money rollers 13 when the fork-type bearing of the present invention is operated, a spacer is provided between each of the rollers 13. The spacer 18 is mainly made of a polymer material. In the first to fourth preferred embodiments above, the mounting hole 122 is formed in the outer ring. In fact, the mounting hole 122 may be formed in the inner ring 11. Referring to the tenth to twelfth drawings, a reciprocating roller bearing according to a fifth preferred embodiment of the present invention mainly includes an inner ring 21, an outer ring 22, and a plurality of rollers 23; A filler member 24. The inner ring 21 has a first annular surface 211 and a mounting hole 212. The inner ring 21 defines a first rolling groove 213 on the first annular surface 211. The first rolling groove 213 is V-shaped. There is a first track surface 214 and a second track surface 215. The mounting hole 212 extends through the first track surface 214 or the second road surface 215 ′ and forms a breakage 216 ′ only for the first road surface 214 or the second track surface 215 to maintain another The contact area between the pavement and the roller is complete; f is damaged (D Wei: if the damage is located on the first-track surface, the second track surface is a complete orbital surface. If the damage is located in the second In the road surface, the first track surface is a complete road surface. In the embodiment, the mounting hole 212 penetrates the first track surface 214 ′ and the damage portion 216 is formed thereon. The outer ring 22 is sleeved on the outer ring 21, and the outer ring has a second annular surface 22, and the outer ring forms a second rolling groove 222 on the second annular surface 221, the second ring The scroll #222 corresponds to the first scroll slot, the second scroll slot 222 is V-shaped and has a complete third lane surface 223 and a fourth track surface 224, and the first track surface 214 and the The walls of the second slots 215 together form an accommodating space 25. Each of the rollers 23 is respectively received in the accommodating space 25, and the filling member 24' is disposed in the mounting hole 212 and fills the damage 216. 201239216 In addition, as shown in the thirteenth figure, in the embodiment of the present invention, in addition to the filler portion 24 filling the damage portion 216 as an example, the filler portion 14 may be chamfered at one end to fill the damage portion 216. In the preferred embodiment, it can be seen that the first rolling groove 213 and the second rolling groove 222 have a "V" shape, which makes the s-shaped space 25 have a quadrangular cross section. The above description of the fifth preferred embodiment of the present invention is the same as that of the first preferred embodiment, and will not be described herein. Referring to FIG. 14 , a sixth preferred embodiment of the present invention is different from the fifth preferred embodiment in that: in order to limit the degree of freedom of the filler member 24 in the direction of the accommodating space 25 , the preferred embodiment The inner ring 21 protrudes from the hole of the mounting hole 212 and bears against the face claw. The filler member % is formed corresponding to the bearing surface 217 - the bearing portion 24 abuts against the bearing surface 217. This will limit the movement of the filler member 24 toward the accommodating space 25, ensuring the flatness of the first track surface 214 at the breakage portion 216. Referring to the fifteenth embodiment, a seventh preferred embodiment of the present invention is different from the sixth embodiment in that the inner portion 21 has a positioning hole 218 for maintaining the position of the filling member 24, The mounting holes 212 are in communication; the filler member 24 has a through hole 242 that is disposed corresponding to the positioning hole 218. A fixed pin 26 is disposed in the positioning hole 218 and the through hole 242. In the preferred embodiment, the positioning pin 26 is inserted into the through hole 242 to clamp the filler member 24, ensuring that the filler member 24 is restricted from moving. Please refer to the sixteenth to seventeenth aspects of the first preferred embodiment of the present invention. In the preferred embodiment, the mounting hole 212 has a round or rectangular surface. However, when the mounting hole 2U has a circular shape, it is necessary to cooperate with a jig 27 to perform the operation of assembling the money roller 23 into the accommodating space ^. In the preferred embodiment t, the wire 27 is a circle _, and the (four) portion has a quadrilateral-shaped channel 27 to provide each of the rollers 23 to fill the accommodating space. As shown in the eighteenth figure, it is worthwhile to mention that in order to reduce the operation of the parent roller bearing in this case, the rafts and frictional resistance generated by the collision of the rollers 23 are attached to each of the rollers. Between 23 is provided - spacer 28. The spacer 28 is mainly made of a polymer material. The reciprocating roller bearing provided by the present invention has the following features: - the reciprocating roller bearing only produces the damage of the _ raceway surface, such as the first readout surface and the fifth preferred embodiment of the first preferred embodiment. The first raceway surface of the towel and the contact area of the third raceway surface 124 of the first preferred embodiment and the second raceway surface 215 and the roller of the fifth preferred embodiment are maintained intact without damage. a. The contact area of the road surface and the roller is large, so that the load capacity of the cross roller bearing of the present invention is higher than that of the prior art. 2. Compared with the prior art, the present invention provides a fork-type roller pumping device because the damage is attached to the track surface, such as the fourth track surface and the fifth comparison in the first preferred embodiment. In the preferred embodiment, the first track surface, so that the filling member only needs to form a fresh-curved surface to fill the damaged portion and maintain the flattening of the third or the first readway surface, and the processing cost of the plane Compared with the conventional formation of a v-groove composite hyperboloid, the yield is high and the yield is high. 6 [Simplified description] 201239216 The first drawing is a perspective view of the first preferred embodiment of the present invention; 1 is a cross-sectional view of a line AA of the first embodiment; the third drawing is an exploded view of the first preferred embodiment of the present invention; and the fourth drawing is a schematic cross-sectional view of the first preferred embodiment of the present invention, showing that the filling member has a bottom end The fifth embodiment is a cross-sectional view of a second preferred embodiment of the present invention; the sixth embodiment is a cross-sectional view of a third preferred embodiment of the present invention; and the seventh embodiment is a fourth preferred embodiment of the present invention.
