When the nut rotates, the fuel tank also rotates. When there is no forced oil supply, the centrifugal force generated during the rotation causes the lubricating grease to adhere to the inner tube wall, and the lubricating performance is greatly reduced. After that, there is a nut-rotating ball screw with an oil-injecting device, which is characterized by S: - the inner nut is sleeved in the outer nut, and the inner nut is provided with: a spiral groove guide The oil-filling & and the guide member are provided with a through hole connected between the _ and the nut, and an inner nut; ^ the guide member is rotated at the same time, because the oil tank is connected with the outer nut, Therefore, the internal nut will rotate when the grease will be rotated. 1352173 *r · / 甩 to the outer layer, there is friction between the grease and the non-rotating fuel tank, so it will not rotate with the guide. The spiral groove on the lead piece pushes the lubricating grease to one end during the rotation, and the lubricating grease thereby presses the through hole to the screw and the nut to achieve the lubricating effect; the main disadvantage of the composition is that the oil tank is relatively The outer nut is sized and fixed to the outer nut, which is easily limited by the size of the outer nut. If the size between the inner nut and the outer nut changes, the guide and the fuel tank need to be re-re- Production, so there is a need for improvement. It can be seen that there are still many missing items in the above-mentioned household items, which is not a designer of a good cover, but needs to be improved. In view of the above-mentioned shortcomings derived from the above-mentioned nut-rotating ball screw with oil-filling device, the inventor of the present invention has improved and innovated, and after years of painstaking research, finally successfully developed and finished the nut rotation of the oil-filling device. Ball screw.

[Embodiment] Please refer to FIG. 1 , the nut rotating spring ball screw with oiling device provided by the present invention mainly comprises: a screw (1), an inner nut (21), an outer nut (24), A plurality of rolling elements (4) and an oil filling device (3). The surface of the screw (1) is provided with a spiral rolling groove (12); the inner nut (21) has a through hole (211) for the screw (1) to pass through, and the surface of the through hole (2 ι) a rolling groove (212) opposite to the rolling groove (12); the outer nut (24) is sleeved on the inner nut (21), and the outer nut (24) is fixed to a passive member ( (not shown), the inner nut (21) and the outer nut (24) are connected by a plurality of bearings (23); the rolling element (4) is accommodated in the rolling groove (12) Roll 5 1352173 slot (212), for the inner nut (21) to make a helical displacement on the screw (1); please refer to Figure 5 and Figure 6, the oiling device (3) is connected to the inner nut (21 One end 'mainly consists of a body (32) and an outer sleeve (34) having a screw seat (321) that extends into the outer sleeve (34) shaft hole (342). And an end cover portion (325), such as an oil storage space (31) to store grease, the screw seat (321) is further provided with a through hole (322) for the screw (1) to pass, please refer to Figure 4 The weight ring (33) is an asymmetrical object, One side is provided with a spiral φ-shaped semi-guide groove (323), which covers the end cover portion (325) of the body (32) to form at least one opening-facing guide groove (324), the guiding groove (324) an oil hole (326) is connected to the through hole (322) at the end, so that the grease can be pushed to the oil supply hole (326) along the spiral advancement principle; the weight ring (33) is shaped like a ring and An asymmetric object having a center of gravity lower than a center of symmetry with respect to the weight ring (33), the screw seat (321) of the body (32) is provided with a card slot (327) for a limiting ring (35) a card is disposed therein, thereby restricting the axial displacement of the weight ring (33), • a gap between the outer sleeve (34) and the weight ring (33), in the axial direction of the outer sleeve (34) An oil hole (341) is formed in the end surface. When the nut rotating device of the present invention has a nut rotating device, the screw rotating ball screw (1) is used when referring to FIG. 3 and FIG. 6 , wherein the oil filling device (3) injects grease into the oil filling hole (341) before the operation. The inner nut (21) is connected to one end of the oil filling device (3) with a pulley (25)' and the pulley (25) has a through hole (251) for the screw to pass through. The inner nut (21) is rotated by the pulley (25) in the material nut (24) (this 6 1352173 ·, " » when the outer nut (24) does not rotate), so that the inner nut (21) is The screw (1) is helically displaced, and the inner nut (21) drives the oiling device (3) to rotate. At this time, the lubricating oil in the oil storage space (31) will be thrown to the outer sleeve by the centrifugal force generated by the rotation (34). Around the inner raft, the pushed grease enters the oil supply hole (326) from the guide groove (324) between the side wall surface (3丨2) of the oil storage space (3丨) and the weight ring (33), which The weight ring (33) is lower than the relative center of gravity because of the center of gravity, so the oiling device (" does not rotate with it when rotating, or the weight (33) The rotation speed is less than the oil filling device (3) so that it has friction with the lubricating grease, so that the lubricating grease can be indirectly squeezed around the outer edge of the weight ring (33), and then the oiling device (3) is rotated. Then, it is hooked into the guiding groove (324) through the semi-guide groove (323) of the weight ring (33), and the lubricating oil hole (326) is injected into the surface of the screw (1) to achieve the lubricating effect. Referring to FIG. 2 and FIG. 7 , the second feasible embodiment of the present invention is that all the components are the same as the first feasible embodiment, and only the semi-guide groove on the weight ring (33) (323) is disposed on the side wall surface (312) of the oil storage space (31); the actuation mode of the embodiment is the same as that of the first feasible embodiment, and the inner nut is driven by the pulley (25). The oil filling device (3) rotates together, and at this time, the lubricating oil in the oil storage space (31) is centrifugally generated by the rotation (4) to the inner circumference of the outer sleeve (34), and the grease is pushed by the oil storage space (8). A guiding groove (324) between the side wall surface (312) and the weight ring (10) enters the oil supply hole (326), Since the center of gravity (10) is lower than the opposite center of gravity, the oiling device (3) does not rotate when it rotates, or the weight of the weight ring (33) is smaller than the oiling device 1352173, 1 (3) ) 'Make it rub with grease, so that the grease can be squeezed indirectly around the outer edge of the weight ring (33), and then through the oil-filling device (3), and from the side of the oil storage space (31) The semi-guide groove (323) of the wall surface (312) hooks it into the guide bow groove (324)' to inject the oil hole (326) into the surface of the screw (1) to achieve lubrication effect. The first feasible embodiment and the first In a second implementation manner, the bearing (23) disposed between the inner nut (21) and the outer nut (24) can be replaced by a rolling member, and the semi-guide groove (323) can be set to a plurality of When the weight ring (33) is covered on the end cover portion (325) of the body (32), a plurality of guiding grooves (324) are formed, and the oil supply holes (326) are also opened relative to the number of the guiding grooves (324). Thereby, the amount of lubricating grease entering the guiding groove (324) can be increased, and the lubrication effect of the lubricating device (3) on the screw (1) can be enhanced.
