Description of the invention: [Technical field to which the invention pertains] The present invention provides a flow structure of a ball screw and a flow element thereof, the purpose of which is to make it impossible to set a lyon at both ends of the nut, Without damaging the tooth peak, the ball can still be made to be the same: the Ma grabbing member is set to have a radial block and an axial block, and the inner L portion has a bribe from the radial direction to the axial direction. The two flow elements are accidentally placed at the axial ends of the cap. The nut corresponds to the radial slot of the flow element and penetrates into the inside of the nut. Pair = body = open: not through to the screw The axial groove inside the cap, ===== The raceway hidden in the thickness of the screw (4), the ball can enter the raceway of the flow avoiding component from the spiral groove of the nut, and then enter the raceway sequentially In the other recirculation path of the recirculation 2, the re-entry into the spiral groove at the other end of the nut, and the configuration of the entire flow path of the nut is carried out by the reflow element (four) block and the groove for the axial support. Not only the 岐 component retains the _ flow path, ^ does not damage the peak of the nut, but ensures that the ball can smoothly roll and return [Prior Art] 0 This J tired towel: 1◦ The structure for the ball head flow cannot be set on the nut face. The two sides of the nut 10 are to be opened on the near sides of the nut 10 - the slots 1 2, 1 3 ' are provided for each of the flow avoiding elements i 5, work 6, the groove i ^; 1 3 on the radial sides of each of the formation - plane bearing 1 2, "2, 131, 132, between the two slots 12, 13 and set up.1300111 ^ The raceway 14 is hidden in the wall thickness of the nut 1 , and the raceway 14 is connected to the groove 2 and 1 3 , and the internal components 1 5 and 16 are internally provided with a self-diameter. The turbulent flow path 1 5 1 , 1 6 1 , which is turned toward the axial direction, the radial end of the return flow path of the 1 through 7 〇 1 , 15 , and the raceway 14 4 =, the two choke elements 1 5, 1 β embedded in the slot 1 2, 1 3, the lanthanum is diametrically opposed, the two reflow elements 1 5, 16 of the choke end end each corresponding to the screw 1 〇 spiral groove 17 When the ball can be rolled to the reflow element 15 at 7 7 , the radial end of the channel 1 1 1 of the choke element 15 enters, then turns to the axial end, and enters the raceway 14 , and then enter the other reflow element i 6 of the chute i 6 i axial end turns to the radial end, and finally with the corresponding end of the nut 10 0 spiral groove 1 7 is connected, and the groove is a complete turbulent path, and the reflow element i 5 or 丄6 is guilty of causing the flow path 1 5 1 or 166 to have a slightly slower avoidance curve. Set to be wider, please refer to Figure 2a, b. Figure ^A is a nut with a large lead angle i 〇, Figure 2B is a nut with a small lead angle 1 〇, Figure 1 When the reflow element 15 or 16 is applied to the nut of Fig. 2A, the width d between the two peaks on both sides of the screw g groove 17 is larger than that due to the larger distance between the spiral grooves i7. The width D of the flow element 1 5 or 16 is such that the slot i 2 or 1 3 of the choke element i 5 or i 6 is embedded, and the entire corresponding choke element 丄 5 or 16 spiral groove is not The lateral tooth peaks 1 8 are completely cut off, so that the balls can roll normally, and the choke elements 15 or 16 are applied to the nut 1 of Fig. 2B, because the spiral groove 7 is small, the spiral The width 0 of the two peaks on both sides of the groove 1 7 is smaller than the width D of the choke element 1 5 or 16 , and the choke element 15 or 16 is privately placed in the slot 1 2 or 13 When 丄2 or 1 3 is opened, it will correspond to the tooth peaks on both sides of the spiral groove 1 7 of the choke element 1 5 or 16. Wang cuts off and returns to i; when the iL component 1 5 or 16 is installed, it will hinder the normal rolling of the ball.
