The valley groove 34 is located at the outermost side of the end portion 31 for receiving the gasket 38 and the wiper 39, and the bottom of the receiving groove 34 forms a screw hole: 34, 111 fixed groove 35 and positioning groove 36 The bottom of the receiving groove 34 is formed so that the fixing groove 35 and the positioning groove 36 are located at the end portion 31 of the nut 3 . The fixing groove % is adjacent to the screw groove 32 other than the screw cap 3. The positioning groove 36 is connected to one side of the fixed groove %. The groove 37 is formed by the outer rolling groove 32 of the nut 30 toward the inside of the nut 3, and is located at the bottom of the fixing groove 35 to form a ball 11 between the fixing groove 35 and the outer rolling groove 32. Rolling groove. The engaging groove 37 is for receiving the ball 11 from the outer rolling groove 32, so that the ball 11 can be pasted into the engaging groove 37 by the rolling groove 32 outside the nut 30. The circulation hole 33 penetrates the nut 30 and communicates with each of the fixing grooves 35 at both ends of the nut 3〇. (iii) The guide block 50 may be, but not limited to, made of a plastic injection molding material, and is placed in a fixing groove 35 of the nut 30 to be fixed to each end portion of the nut 3'. The guide block 50 includes a column portion 51, a tapered portion 52 and a return groove 53. The two sides of the tapered portion 52 further define a barrier rib 54 and a locking wing 55, respectively. The return groove phantom bends through the column portion 51 of the guide block 50 and the tapered portion 52 to form a groove for the rolling operation of the ball 11 in the guide block 5'. The end of the return groove 53 at the edge of the tapered portion 52 corresponds to the inner rolling groove 21 of the screw 20, so that the ball U can be rolled in and out of the inner rolling groove 21 and the return groove 53. The return groove 53 is located at one end of the edge of the column portion 51 to open the circulation hole 33 of the nut 30, so that the ball 11 can be rolled into and out of the circulation hole % and the return groove 53. The return groove 53 is coupled with the engaging groove 37 of the nut 30 to form a guiding passage 60. The guiding passage 60 is slightly larger in size than the diameter of the ball η, so that the ball M326093 can be rolled in the lead channel 6〇. The guide passage 6 is for guiding the ball η* into and out of the outer rolling groove 32 (the inner rolling groove 21) and the circulation hole 33, so that the ball u is steered back at the respective dam portions 31 of the nut 3〇. The barrier rib 54 extends from the side of the return groove 53 into the inner rolling groove 21 of the screw #2〇 to block the operation of the ball ring in the inner rolling groove 21, and the ball 11 is placed in the inner rolling groove 21. Therefore, the ball I can smoothly enter and exit the guiding channel 6〇 of the guiding block 5〇. The locking wings 55 are protruded from one side of the 'cone portion 52 of the guiding block 50, and are located on different sides from the blocking rib 54. The locking wings 55 are embedded in the positioning groove % of the nut 3〇 to The radial direction of the nut 30 will guide the end portion 31 of the nut 30 to the end of the nut 30.

The end 31 of the crucible. As shown in "Fig. 1" and "Fig. 5", the ball U is originally rolled between the inner rolling grooves 21 of the outer rolling groove 32 of the nut 3〇. When the ball 11 is moved to the end portion 31 of the nut 30 side, the ball η is blocked by the dam blocking rib 54 of the guiding block and is separated from the inner rolling groove 21 and the outer rolling groove 32, and simultaneously enters the return groove 53 and The engagement groove 37 is formed in the guide channel 60. Then, the ball u is steered along the path of the guide passage 60 to enter the one end of the circulation hole 33 of the nut 3 at the other end of the guide passage (9). When the ball n is moved to the end portion 31 of the other side of the nut 30 via the circulation hole %, the guide block 5 turns the ball u back between the inner rolling groove 21 and the outer rolling groove 32, thereby continuing the cycle. Running. . In the present invention, the guide channel 60 for reflowing the wire guiding ball 11 is formed by the return groove S3 of the guiding block 5 and the engaging groove 37 of the nut 3〇. Injection molding of plastic materials can maintain high productivity in production and low cost of M326093. The connecting groove 37 is directly installed on the metal nut%, which is not only easy to manufacture, but also can effectively improve the guiding channel. The anti-wear ability of the outer rolling groove at the joint is further improved to extend the operating efficiency and service life of the ball screw assembly.
