Description

1358496, invention description: [Technical field of the invention] is a direct = τ transmission component, especially a transmission component that is converted into a linear motion by a rotary motion, a chain of the body. W transmission is intermittently scrolled [Prior Art] One press In order to meet the requirements of customers, the condition that the transmission is 7 inches in order to meet the requirements of high speed and quietness and prolonging the use of the life is so that the chain of the spacer rolling elements is installed in the transmission element so that the rolling elements do not collide with each other during operation, and When the return flow path to the shaft element is run, the rolling elements are not misaligned, so that the circulation of the transmission element can be smoother. The need for inter-speed operation' and prolong the life of the transmission components. • In the above, as in the US Patent Nos. 6089117 and 6286383, a chain is provided in the transmission element. See U.S. Patent No. 6,891,17 for the case of Figures 2, 8, and 17, which mainly disclose that the guiding member 3 has guiding sections 15 (10) at both ends, but the chain is not illustrated in the rolling element load zone ( Refers to the movement of the nut and the screw. Furthermore, U.S. Patent No. 6,286,383 discloses the addition of a spiral element inside the nut to the inner diameter of the nut for guiding the chain in the load zone. 1358496 The first l does not explain the chain thinness in the load zone Zhao potential state, please refer to the figure - the chain is mainly provided by the rolling body 73 two = partition 72' and the connection of each spacer to the connection part f The connecting portion 71 is located between the outside of the screw = Γ 2 in the load region, and the thickness τ of the connecting portion 71 is calculated by the dimension of the un-nut 6

(1) interferes with the outer diameter 52 of the screw (as shown in the first figure, the side joint portion 7 1 is attached to the outer diameter 5 2 to cause friction), which causes the joint portion 71 to be distorted (such as the second In the figure, the roller (four) 73 cannot be attached to the spacer 72, which causes the spacer 72 to be unilaterally stressed and accelerates the wear of the chain, so that the service life of the chain is shortened, and the chain circulation is not smooth. The connection is broken and the transmission element cannot be operated or shortened.

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 which can achieve the object of the following invention is born. That is, the primary object of the present invention is to prevent the chain from circulating in the transmission element without interference. For the purpose of the above, the present invention is a chain type transmission element 1358496, which comprises: - a screw having an outer surface provided with a spiral rolling groove; a screw collar having a through hole, the passage The inner edge of the hole is provided with a screw material for the rolling groove, the roller (4) and the rolling groove system constitute a load path; and the nut is provided with a reflow element, and the reflow element is provided with a return flow path. The return channel is connected to the load path to form an infinite orbit;

The rolling module-rolling module is disposed in the infinite track, the chain system comprises: a plurality of rolling elements and a chain, the plurality of spacing portions and the two connecting portions are located at the door of the rolling body 》海连接σ|Μ is located on both sides of the 5H partition and connects the partitions, and the connection consumes - thickness Κ, the thickness (4) conforms to the following formula: Κ<2χ PCD)2 (BD + S^

PCD: pitch diameter 2~J ~f * S :, rolling element spacing D: screw outer BD: rolling element diameter thickness K must conform to the above-mentioned Park Zengong variant because the chain is spiraled on the surface of the screw When the hard-working time is hard, the movement path of the link of the chain is not located on the diameter of the pitch circle, but it will be smaller than the diameter of the pitch circle. If the link is not interfered with by the farmer, the joint is distorted. 'The rolling element cannot be fitted to the 35th part, and the f chain is not run on the load path (4). Therefore, the thickness κ is such that the joint portion does not interfere with the outer diameter of the screw, and the chain is operated more smoothly. Furthermore, after deriving from the above formula, the diameter of the virtual circle formed by the central motion of the joint portion is smaller than the diameter of the virtual circle formed by the central motion of the rolling body, and the diameters of the virtual circles of the two are at least different: H = PCD-2x^^~.^j _|^^+Sj2 〇 Finally, the joint has a width which is smaller than the pitch of the load path, so that the adjacent joints do not interfere with each other. . For a better understanding of the features and technical aspects of the present invention, reference should be made to the description of the embodiments of the invention. By. 1358496 [Embodiment] _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ There is a spiral rolling groove 1 1 ;

a nut 2 is provided with a through hole 2 3 '. The inner edge of the through hole 2 3 is provided with a spiral rolling groove 2 1 opposite to the rolling groove 1 1 , and the rolling groove 1 1 and the rolling groove 2 1 Forming a load path; and the nut 2 is provided with a reflow element 3, which is provided with a return flow path (not shown), and the return flow path is connected with the load path to form an infinite way; A rolling module 4' is disposed in the infinite track, and the rolling module comprises: a plurality of rolling elements 43 and a chain, the chain having a plurality of spacers 4 2 and two connecting portions 4 1 The spacer portion 4 2 is located between the rolling elements 43, and the connecting portion 4 1 is located

Each of the spacers 4 2 is connected to each of the spacers 4 2 , and the connection portion 41 has a thickness K ′ which is in accordance with the following calculation formula: Κ < 2 χ 丨 (PCD} 2 (BD + S^\ 2 /), [2 J l 2 J 2 ) pitch diameter PCD: S: rolling element spacing D: screw outer diameter BD: rolling element diameter 7 1358496 a thickness K emperor meets the above 吋 _ 炙 曼 曼 查 查 查, the chain When the surface of the screw 1 is spirally moved, the path of the joint portion 4 of the chain is not located on the pitch diameter (pcD), but is smaller than the diameter of the circle (P c D ), if the joint portion 4 i does not pass. The design easily interferes with the outer diameter i 2 of the screw, which in turn causes the joint portion 4 to be twisted, so that the rolling element 4 3 cannot fit the spacer portion 4 2, and the chain does not run smoothly in the load path. Therefore, by calculating the thickness gauge, the joint portion 4 1 does not interfere with the outer diameter of the screw 1, and the chain is operated more smoothly. Furthermore, after deriving from the above formula, the diameter of the virtual circle formed by the movement of the center 1 of the joint portion 4 1 is smaller than the diameter of the virtual circle formed by the movement of the center J 2 of the rolling element, both of which are virtual circles. The diameter is at least different: H = Pa) -.
