[0002] Please refer to Fig. 1, the conventional ball screw 21 is matched with a nut 31, so that the ball screw 21 is screwed in the nut 31. The displacement of the screw rod 21 may cause the screw rod 21 to rotate at a fixed point to cause the displacement of the nut 31. However, no matter which transmission method is used, the helical groove 32 of the nut 31 and the raceway 22 of the screw rod 21 and the raceway 22 rolling in the raceway 22 The balls 23 must be properly lubricated to keep the screw 21 or the nut 31 moving smoothly, and reduce the wear of the screw 21, the nut 31, the balls 23 and other components; One side end face of cap 31 is provided with a radial through hole 312 to penetrate to the axial through hole 311 of nut 31, and this radi

Example Embodiment

[0038] Please refer to Figures 2A, 2B and 3, which is the first embodiment of the self-lubricator 40 of the present invention. The self-lubricator 40 of this embodiment is generally in the shape of an inverted T-shaped body, and a fixed rod is formed at the longitudinal end of the self-lubricator 40. 41, its lateral end forms an arc-shaped steering rod 42; the upper half of the fixed rod 41 is provided with an external thread portion 411, and an oil through hole 43 is provided in the middle position, and the inside of the fixed rod 41 faces from the oil through hole 43. An oil seepage hole 44 is provided between the rotating rod 42; the steering rod 42 forms an arc-shaped body with both ends slightly facing downwards. The bottom surface of the steering rod 42 corresponds to the oil seepage hole 44 of the fixed rod 41 and is provided with a space larger than the oil seepage hole 44. An oil-absorbing member 48 can be placed in the cavity 45, and the bottom end of the oil-absorbing m...

Abstract

There is disclosed a ball-screw self-lubricator and at the bottom of the self-lubricator is disposed an oil-sucking element standing on the ball track of the screw, so as to lubricate the ball track in different positions. On each side of the self-lubricator is disposed a steering part capable of leading the ball rolling in the screw ball track into a return pipe and then into another ball track position of the screw. Both sides of the oil-sucking element protruded from the corresponding steering parts can contact with the return ball and the ball is lubricated by the oil-sucking element. The oil-sucking element can store the lubricating oil, so it can lubricate the screw ball track continuously during the driving of the ball-screw.

Description

technical field [0001] The invention relates to a self-lubricating device for a ball screw. Background technique [0002] Please refer to Fig. 1, the conventional ball screw 21 is matched with a nut 31, so that the ball screw 21 is screwed in the nut 31. The displacement of the screw rod 21 may cause the screw rod 21 to rotate at a fixed point to cause the displacement of the nut 31. However, no matter which transmission method is used, the helical groove 32 of the nut 31 and the raceway 22 of the screw rod 21 and the raceway 22 rolling in the raceway 22 The balls 23 must be properly lubricated to keep the screw 21 or the nut 31 moving smoothly, and reduce the wear of the screw 21, the nut 31, the balls 23 and other components; One end face of the cap 31 is provided with a radial through hole 312 that runs through the axial through hole 311 of the nut 31, and the radial through hole 312 is provided with an oil delivery pipe 313, which is then connected to an automatic oilin...
