Description

Technical Field

[0001] This invention relates to ball screws, and more particularly to a ball screw with a dustproof function. Background Technology

[0002] A ball screw is a component widely used in precision mechanical transmission systems. It is typically used to convert rotary motion into linear motion and features high efficiency, low friction, and precise control. However, during operation, if dust or debris enters the ball screw, it can affect its operation and precision, leading to reduced service life.

[0003] Furthermore, most ball screws currently incorporate dustproof structures to reduce the impact of dust. For example, dust covers are installed at both ends of the ball screw's threads to prevent external dust from entering the thread grooves. However, some dust can still fall into and accumulate inside the dust covers, potentially affecting the ball screw's operation or accuracy. Additionally, dust present inside the dust covers or sealing caps can also affect the sealing effect. Therefore, the applicant's research motivation stems from the need to develop an effective dust removal structure for ball screws.

[0004] In view of this, the applicant has devoted himself to studying the aforementioned prior art and applying theoretical principles to try his best to solve the above-mentioned problems, which has become the target of the applicant's improvement. Summary of the Invention

[0006] To achieve the above objectives, this application proposes a ball screw with a dust removal device, comprising a screw, a nut, and the dust removal device. The nut is screwed onto the screw. The dust removal device is disposed on the nut and includes a ring seat and an oscillating element. The ring seat is engaged with one side of the nut. The oscillating element is disposed within the ring seat.

[0007] In one embodiment of this invention, the nut has a flange on one side, and the annular seat passes through the inside of the flange.

[0008] In one embodiment of this invention, the ring seat includes a ring body and a cover that covers the ring body.

[0009] In one embodiment of this invention, the cover has a groove formed on the side away from the nut, and the ring is placed in the groove.

[0010] In one embodiment of this case, the cover has a raised ring formed on the side facing the nut, and the two ends of the nut are respectively provided with ring grooves. The raised ring passes through the nut, and the cover is positioned in the ring groove.

[0012] In one embodiment of this case, the inner wall surface of the nut is formed with multiple spiral grooves, and the ring body is provided with annular grooves corresponding to the spiral grooves.

[0013] In one embodiment of this invention, the dust removal device further includes a shock-absorbing plate disposed between the nut and the ring seat.

[0014] In one embodiment of this case, the number of dust removal devices is a pair, with dust removal devices respectively provided on both sides of the nut.

[0015] In one embodiment of this invention, the ball screw further includes a control element electrically connected to the oscillating element, the oscillating element being controlled by the control element to generate vibration.

[0016] Compared to existing technologies, the ball screw of the present invention is equipped with a dust removal device. The dust removal device includes a ring seat and an oscillating element disposed on the ring seat, and the ring seat is connected to one side of the nut; in addition, a shock-absorbing plate can be disposed between the nut and the ring seat to absorb the vibration transmitted to the nut and the screw, so as to avoid the vibration affecting the precision of the ball screw transmission; accordingly, the oscillating element can generate oscillation when it runs to remove the dust accumulated between the screw and the nut in a timely manner, thereby achieving the dust removal effect and maintaining the normal operation of the ball screw.
