Description

Technical Field

[0001] The present application relates to the technical field of ball screws, and in particular to an anti-fall-off dust ring. Background Art

[0002] Ball screws are ideal for converting rotary motion into linear motion, or vice versa. They are the most commonly used transmission element in tool machinery and precision machinery. Their primary function is to convert rotary motion into linear motion, or torque into repetitive axial force, while offering high precision, reversibility, and efficiency. Due to their minimal frictional resistance, ball screws are widely used in a variety of industrial equipment and precision instruments.

[0003] An existing patent (publication number: CN211315010U) discloses a dust seal for a lead screw nut. The seal comprises a main body with an annular connecting portion integrally molded on one side of the body, located at the inner edge. Annular teeth are integrally connected between the outer wall of the connecting portion and the side wall of the main body. This design reduces friction between the seal and the lead screw nut, preventing the seal from loosening and slipping, and improving dust protection stability.

[0004] During use, the above-mentioned document realizes the connection between the dust ring and the nut by installing the connecting parts, but the tightness between the dust ring and the nut is weak, and it is still possible that the sealing ring will fall off during the sliding process of the nut. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides an anti-falling dust ring, which has the advantages of improving practicality and solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: an anti-falling dustproof ring, comprising a sealing ring base, the outer surface of which is equipped with a plurality of strong magnets distributed in a circular pattern, a tightening ring is provided above the sealing ring base, and the outer surface of the tightening ring is provided with a plurality of slots distributed in a circular pattern, and rods are inserted into the interior of the plurality of slots.

[0007] Through the above solution, the nut can be adsorbed by providing a strong magnet, so that the sealing ring base can be stably placed in the nut.

[0008] Furthermore, the sealing ring base is made of polytetrafluoroethylene.

[0009] Through the above solution, the sealing ring base is set to polytetrafluoroethylene, which can make it have extremely excellent chemical stability and is almost unaffected by any chemical reagents, including strong acids, strong alkalis and various organic solvents. In addition, it also has an extremely low friction coefficient and excellent lubricity.

[0010] Furthermore, a first internal thread groove is formed on the inner wall of the sealing ring base.

[0011] Through the above scheme, the first internal thread groove is opened to be threadedly connected to the outer surface of the screw, so that the sealing ring base can maintain synchronous sliding with the nut, and because the sealing ring base is polytetrafluoroethylene, the friction is low, which can make its synchronization rate with the nut higher.

[0012] Furthermore, an external thread is provided on the outer surface of the sealing ring base, a sealing cover ring is provided above the sealing ring base, and a notch is provided on the bottom surface of the sealing cover ring, and the notch is adapted to the external thread.

[0013] Through the above solution, installing the sealing cover ring can seal the sealing ring base, avoid the sealing ring base from being oxidized too quickly, and at the same time improve the dustproof effect inside the nut, thereby improving the overall practicality.

[0014] Furthermore, the sealing cover ring is made of polyethylene.

[0015] Through the above solution, the sealing cover ring is made of polyethylene material, which can make it have good wear resistance and weather resistance, can be used for a long time in outdoor environment without aging, and can resist corrosion from various chemical substances, including acid, alkali and salt solutions.

[0016] Furthermore, a rubber ring is installed on the inner wall of the sealing cover ring, and a second internal thread groove is opened on the inner wall of the rubber ring.

[0017] Through the above solution, the cooperation between the second internal thread groove and the rubber ring can make the contact with the thread on the outer surface of the screw tighter, and at the same time significantly improve the sealing of the nut, preventing external dust from entering the interior of the nut.

[0018] Furthermore, the tension ring is made of styrene-butadiene rubber.

[0019] Through the above solution, the tensioning ring is set to be made of styrene-butadiene rubber material, which can make it have good oil resistance, wear resistance, crack resistance and oxidation resistance, and excellent tensile strength, elongation and resilience.

[0020] Furthermore, a plurality of circumferentially distributed protrusions are fixedly connected to the outer surface of the tightening ring, and the material of the plurality of protrusions is the same as that of the tightening ring.

[0021] Through the above solution, providing multiple protrusions can increase the resistance between the tightening ring and the inner wall of the nut, so that the tightening ring can be connected to the inner wall of the nut more stably, thereby preventing the tightening ring from falling off.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The anti-falling dustproof ring can adsorb the nut by setting a strong magnet, so that the sealing ring base can be stably placed in the nut. The tightening ring and the insertion rod cooperate to deform the tightening ring and squeeze the inner wall of the nut after the insertion rod is inserted into the tightening ring, so that the tightening ring can closely contact the inner wall of the sealing ring, thereby increasing the resistance between the two and preventing it from falling off.
