Description of the invention: [Technical field to which the invention pertains] The present invention relates to a nut-rotating ball screw, and more particularly to a nut-rotating ball screw having a lubrication device. [Previous technology] The nut rotary ball screw system is formed by the outer ring of the nut and the outer ring of the bearing and the working platform (4), and the power motor transmits the power to the nut by the skin V. The nut is rotated relative to the screw, and the rotational torque is converted into an axial movement to drive the working platform. The screw is mainly fixed by the screw, so there is no inertial force when the screw rotates, and the screw with a slender ratio can also advance at a high speed. It can be used with a smaller drive motor; its main ^ is applied to semiconductor machinery, wood-machines, conveyors, etc., and it is not difficult to say about the importance of various industrial applications today. U.S. Patent Nos. 5,809,838 and 6,732,600 disclose a lubricating device for a screw-to-turn ball screw. The lubrication of the scale structure is as shown in the first figure 'through the bearing outer ring 940' - through hole 9 4 The internal lubrication device and the inner portion of the bearing 94 are connected, and the nut 92 is also opposed to the through hole 9 21 so that the external lubricating device can put the grease, the nut 9 2 into the lubricating screw 9 and the ball. The purpose of 9 3 'but these lubrication methods have at least the following problems: 200916674 First, the nut 9 9 and the bearing outer ring 9 4 加工 processing, will lead to the overall rigidity. Second, the grease must fill all the space inside the nut 9 2, and can be continuously guided to the thread groove g丄〇 and the internal thread 902 between the screw 9 i and the nut 92, so it is impossible to determine whether there is any Achieve the effect of lubrication. Furthermore, it is applied to the lubrication of the general-purpose ball screw. As disclosed in U.S. Patent No. 6,364,058, a self-lubricating oil tank is attached to the end face of the nut, the lubricating oil can be stored in the oil tank, and a lubricating device is provided to contact the nut. Lubrication, the problem can not be used in the nut rotary ball screw, because the tank is fixed _ cap, the tank will rotate, in the absence of forced oil, when the rotation will cause centrifugal force will make the oil stick attached to the inner tube On the wall, it cannot be effectively lubricated. SUMMARY OF THE INVENTION Based on the above problems of the conventional lubricating device, the inventors of the present invention have been researched and improved, and the invention for the purpose of finalizing the invention has been born. That is, the main object of the present invention is to provide a lubricated farmer at the end of the nut-rotating ball screw, and to achieve a reliable lubrication effect by forced oiling. In order to achieve the above object, the nut rotating roller 200916674 of the present invention has a screw thread, which comprises: a screw threaded with a threaded groove; and a rotary nut which includes an outer ring and a screw俜A Ashi ★ Right-hand bearing and a bearing edge bite the phase, ', 1 structure' is set on the screw, 1 inner edge is sighed with the thread groove of the screw - built in the screw The outer edge of the cap; Lai Cheng (4) County = the sleeve of the bearing by the bearing as the bearing of the nut bearing the movement; 1 shell and the nut to rotate relative to the rotation of a number of balls, the system is placed in the thread groove Between the threaded groove; an oil supply device 'which provides grease; a turbid device' includes a body, a ring and a bearing, and the Hengben _ has a plurality of oil holes which are fixed to the nut The end face, the collar 4=the medium is co-located with the body, so that the body can be moved relative to the 'clothing movement, and the lubricating oil is driven into the body, the collar and the bearing. In the oil collecting space, the oil collecting space is in communication with the oil holes, and the grease flows into the screw through the oil hole Surface. In order to further understand the features and technical contents of the present invention, reference should be made to the following description of the embodiments of the present invention and the drawings. 200916674 [Embodiment] Please refer to the second to fifth figures, the nut rotary ball screw of the present invention includes: a screw 1 having a thread groove 1 1; a rotary screw The cap 2 includes a nut 2 2, a plurality of bearings 2 3 and a bearing outer ring 2 1 ; the nut 2 2 is a hollow structure, and is sleeved on the screw 1 , and the inner edge is oppositely disposed a thread groove 2 2 1 of the thread groove 1 1 of the screw 1; the bearing 2 3 is sleeved on the outer edge of the nut 2 2; the bearing outer ring 2 1 is sleeved on the bearing 2 3 The bearing 2 is used as a medium for the nut 22 to rotate relative to the nut 22; a plurality of balls X' are disposed between the thread groove 2 2 1 and the thread groove 1 1; An oil supply device (not shown) for providing grease; a lubrication device 4 comprising a first fixing member 4丄a second fixing member 4 2, a forcing by the bearing 4 3, a body 4 4, a collar 4 5, a grease nozzle 4 6; the body 44 is fixed to the end face of the nut 22, and is provided with a plurality of oil Hole 4 4 2 1 , first-class surface 4 4 1 , first groove 4 4丄丄, first surface 4412, second-level surface 4 4 2, third-level surface 4 4 3, third surface 4 4 2, the receiving part 4 4 4 (as shown in the fifth figure); 200916674 The collar 4 5 is provided with the first-out 11, the second playing surface 4512, the fourth ring surface 45, the second groove 45 surface 453 a fourth bearing surface 4 5 3 ] 7^ a third inner ring 4 5 4 , which is fixed by the bearing 4 as shown in FIG. 5 , so that the body 4 4 can be opposite to the The main body 4 4 cooperates with the inner ring 432 and the outer 5 of the collar 4 to perform a rotary motion 'the shaft, and the 3 1 system is respectively sleeved on the body 51 and the first and the inner side of the collar 45 The toroidal surface 4 412 and the second surface 4512 are in the center of the heart. The first fixing member 41 is engaged with the second groove 4 5 ii to the first groove 44lim. 42 is engaged in production and further restricts the axial freedom of the bearing 43, and the fixing hole 4 5 4 of the sleeve core 45 and the oil collection space "Connected, /, for the nozzle to be fixed, the outer end of the nozzle 4 6 is / / oil supply shocked by the oil supply farm to force the grease into the second body 44 Class face 4 4 2, third collision face 4 4 2 2, third class face 4 4 3, and second inner ring face 4 5 of the collar 45 2, fourth stop face 4 5 3 1 , third inner The annular surface 4 5 3 and the bearing 43 are formed in the oil collecting space 9 ,, and the oil collecting "90" is in communication with the oil holes 4 4 2 1 and the grease is further passed through the oil holes 4 4 2 workers flow into the surface of the screw 1 to achieve the effect of lubrication; in addition, the receiving portion 4 4 4 of the outer end surface of the body 4 4 is provided with 200916674 a wiper 3 1 setting i, ..., ...
