Description of the Invention: [Technical Field] The present invention relates to a spacer for a roller, which can be used for a transmission product in which a roller is provided and rolling of a roller is applied to reduce frictional resistance, for example, a roller screw, Linear roller slides or roller bearings. [Prior Art] Roller screws, linear roller slides or roller bearings commonly used in precision machinery are continuously arranged in the cycle, and spacers are placed in each roll (four) to make the roller Adjacent rollers do not directly contact the collision to reduce noise and roller friction damage, so the structural shape of the spacer is particularly important. Two roller spacer designs are disclosed in the U.S. Patent No. 4,759, 968, and the Japanese Patent No. 2003206932. The first figure is a spacer of the U.S. Patent No. 4,759, 863, and the second is a spacer of the Japanese Patent No. 2003206932. The prior art discloses that the spacer i 7 has a cylindrical shape on each of the opposite sides. The recesses 171, 174 of the face are received in the recesses 117, 174 and are in nearly full contact with the sides of the recesses 171, 174, due to the recess i 7 of the roller and the spacer i 7 , 1 7 4 The sides are almost simultaneously in contact, so there will be no gap between the roller and the spacer, and the roller cannot be provided in the recess i 7 i, the work 7 4 has a relatively obvious free movement stroke which will make When the roller bearing or linear actuator is manufactured with a roundness error or a pitch diameter error', or when the radius of curvature of the track changes, the contact position between the spacer and the roller cannot be adjusted accordingly.间隔 And in the gap of the U.S. Patent No. 4,759,683, as shown in the first figure, the interval 3 of the inner side of the spacer i 7 is smaller than the outer side length b, that is, a < b. The reason for this design is that the spacer is limited by the outer edge of the inner ring of the roller track and the inner edge of the outer ring of the track, and the diameter of the outer ring is not equal to the diameter of the inner ring. Unfortunately, when the pitch diameter of the bearing is different, the ratio of the diameter of the outer ring to the diameter of the inner ring will be different, which will result in the spacer not being shared with roller bearings or linear actuators of different pitch diameters. Another spacer configuration is disclosed in PCT Patent Application No. 00/34673, which, as shown in the third figure, has a thin plate-like body 2 and four sides on each side of the body 2. The independent protruding columns 5 which are not connected to each other, the structure of the spacer 8 will make the protruding column 5 less strong and easily break, and the protruding column 5 does not increase the strength of the body 2 of the spacer 18. The function will cause the body 2 of the spacer 18 to be easily warped, and the spacer 2 provides the roller with a phase, free movement stroke, and the inner side of the spacer 18 has a length smaller than the outer side length. Will cause the roll (four) bearing or _# ^ the bulging column 5 of the spacer 18 to dry, = turn when the 'roller and the tribute dry / step and the operation is not smooth. Based on the shortcomings of the above-mentioned prior art, it is clear that there is still room for improvement in the conventional spacer. SUMMARY OF THE INVENTION Based on the problems of the above-described conventional techniques, the inventors of the present invention have been researched and improved, and the invention of the purpose of "Weida m (4) is born. 3 I7 The primary object of the present invention is to invent a spacer for a roller. In addition to the rollback function (4), the spacer can provide a relatively free movement of the roller to absorb the roller draw or linear actuator. The pitch diameter error caused by the roundness error during manufacturing, or when the radius of curvature of the track changes, the contact position between the spacer and the roller can be adjusted accordingly, and the spacer can be used for different pitch circles. Diameter roller bearing or linear transmission device; a secondary object of the present invention is to design a spacer configuration to increase the strength of the spacer body so that the spacer body does not warp when made into a thinner shape. Deformation; Spacer: ..: The invention can be used for the spacer between the rollers: the configuration of the package: there is - a relatively "moving stroke, the (four) body, the body is - thin plate, On the first side of the body, the ribs are disposed on the second side of the body with respect to each other: the second ribs of the second side are formed by the first side and the second side. Flat, and the shell and the first The side surface is in line contact with the roller, the first side and the second side are in a square shape, and the second rib of the first rib disk forms four sides of the square, and the extending direction of the first rib is perpendicular to The second rib can increase the strength of the spacer body, and can also make the body of the spacer into a thinner shape without deforming. The outer rib and the second rib can be approximately triangular. However, the oblique side is a concave circular arc, a triangle or a convex cylindrical shape. When the shape of the rib is approximately triangular but the oblique side is a concave circular arc shape, the radius of curvature of the concave arc is true. Equal to the radius of the roller, when the roller is in contact with the intermediate portion of the first side of the spacer body, the roller is held between the two first ribs and does not fully contact the two first ribs. The column and the two ribs are spaced apart so that the rollers do not simultaneously contact the two first ribs, and the roller is provided with a relatively free movement between the two first ribs. When the roller and the spacer body are In the second time, the rainbow will buckle LT The field contact t-pillar is maintained in the two second ribs and the two ribs are fully pulled and the two are in the m-column and the second ribs are spaced apart from each other (four) and the second rib is in the second Between the ribs, there are - (4) free material columns for the purpose of clearly illustrating the implementation features of the present invention, and the advantages and practical ways of using the present invention: According to the above, the present invention is a spacer for the roller. Each of the two sides has two ribs 'and the ribs on the same side are parallel to each other, but the ribs on the side are perpendicular to each other', and the strength of the spacer body can be increased, so that the spacer body is made thinner. The distortion of the charm, in addition, because the two parallel ribs on the same side are not fully connected with the roller, the roller does not contact the two ribs at the same time. Therefore, the roller can be provided between the two ribs which are parallel to each other. The length of the trip is to absorb the pitch diameter error caused by the roundness error of the roller bearing or the linear actuator when manufacturing, or the contact position between the spacer and the roller when the curvature of the obedience changes. Can be adjusted accordingly' Commonly used for roller bearings or linear actuators with different pitch diameters. In order to further understand the features and technical contents of the present invention, reference is made to the following description of the embodiments of the present invention and the drawings. Limiter. [Embodiment] Please refer to the fourth A, B, c, fifth, β, c and sixth A, B, and C diagrams, and the present invention is a spacer for the roller 'the spacer The configuration includes: a body 1 having a thin plate shape, two first ribs iii parallel to each other on the first side 1 1 of the body ,, and two mutual sides ii on the second side i 2 of the body 1 The parallel second ribs 2 1 'the first side surface 1 i and the second side surface i 2 are planes with respect to the first side surface 1 1 and the second side surface i 2 , and the first side surface η and When the second side 12 is in contact with the roller 2, the first side 11 and the second side 12 are in a square shape, and the first rib 111 and the second rib 12 U form four sides of the positive (four). The extending direction of the first rib ill is perpendicular to the second rib 1 2 1 ', so that the strength of the spacer body i can be increased, and the body 1 of the spacer can be made into a thinner shape without being distorted. The first rib 1 ii and the second rib i 2 丄 can be approximately three (four) as in the fourth A and B drawings, but the concave side is a concave circle 8 difference, or when the curvature of the obedience is half When the diameter changes, the contact position between the spacer and the roller can be adjusted accordingly, and the spacer of the present invention does not need to have a design in which the inner side length is smaller than the outer side length, and can be applied to rollers of different pitch diameters. The bearing or the linear transmission device, furthermore, has two pairs of ribs on opposite sides of the spacer of the present invention, and the ribs on the same side are parallel to each other, and the ribs on the different sides are perpendicular to each other. 10. The spacer body has better strength, and the spacer body can be made into a thinner shape, and the distance between the roller and the roller can be reduced, so that the roller bearing or the linear actuator of the same specification can be set more.
