Description

Technical Field

[0001] This utility model relates to the field of industrial robot joint transmission technology, and in particular to a protective structure for robot deep groove ball bearings. Background Technology

[0002] Deep groove ball bearings have become a core component of industrial robot joint transmission systems due to their compact structure, low coefficient of friction, and high limiting speed. Using high-precision deep groove ball bearings can reduce robot joint positioning errors and meet the rapid response requirements of collaborative robots.

[0003] The deep groove ball bearings currently used in robots have poor self-protection. External dust and other impurities can easily enter the bearing. Once these impurities enter the bearing, they will continuously rub and collide with the bearing's raceways, rolling elements and other key components as the bearing rotates at high speed. This continuous interaction will gradually damage the surface smoothness and precision of the bearing, causing varying degrees of wear on the deep groove ball bearing, which seriously affects the normal operation of the robot. Utility Model Content

[0004] This utility model relates to a protective structure for deep groove ball bearings in robots, which solves the problem that the existing deep groove ball bearings equipped in robots have poor protective performance in practical applications, and that dust and other impurities in the external environment can easily penetrate into the bearing, thus causing wear of the deep groove ball bearing.

[0005] In a first aspect, this utility model provides a protective structure for a robot deep groove ball bearing, specifically comprising: a bearing, a protective outer plate, an outer bolt, a protective inner plate, and an inner bolt; the outer protective plate is connected to the outside of the bearing outer ring, and the inner protective plate is connected to the outside of the bearing inner ring, with the inner protective plate located outside the outer protective plate; the outer bolt is connected to the outside of the bearing outer ring, and the outer bolt is connected to the outer protective plate; the inner bolt is connected to the outside of the bearing inner ring, and the inner bolt is connected to the inner protective plate.

[0006] Furthermore, the outer protective sheet and the inner protective sheet are in rotatable contact. The outer protective sheet is surrounded by two dustproof ring grooves, and the inner protective sheet is surrounded by two dustproof ring plates, which are located within the dustproof ring grooves.

[0007] Furthermore, the outer ring of the bearing is surrounded by mushroom-shaped outer pillars, and the outer protective plate is surrounded by arc-shaped external connecting holes. The diameter of one end of the arc-shaped external connecting hole is larger than the diameter of the other end, and the mushroom-shaped outer pillars are connected to the arc-shaped external connecting holes.

[0008] Furthermore, the bearing outer ring is provided with an external thread blind hole, the protective outer plate is provided with an external fixed hole, the external fixed hole is connected to the external thread blind hole, the external bolt is connected to the external fixed hole, and the end of the external bolt is threadedly connected to the external thread blind hole.

[0009] Furthermore, the bearing inner ring is surrounded by a mushroom-shaped inner column, and the inner protective plate is surrounded by an arc-shaped inner connecting hole. The diameter of one end of the arc-shaped inner connecting hole is larger than the diameter of the other end, and the mushroom-shaped inner column is connected to the arc-shaped inner connecting hole.

[0010] Furthermore, the bearing inner ring is provided with an internal thread blind hole, the protective inner plate is provided with an inner fixed hole, the inner fixed hole is connected to the internal thread blind hole, the inner bolt is connected to the inner fixed hole, and the end of the inner bolt is threadedly connected to the internal thread blind hole.

[0011] This utility model provides a protective structure for deep groove ball bearings in robots, which has the following beneficial effects: When this utility model is in use, as the inner ring of the bearing rotates, the inner ring drives the protective inner plate to rotate synchronously. Through the cooperation of the dustproof ring plate and the dustproof ring groove, it effectively prevents external impurities from entering the interior of the deep groove ball bearing and causing wear, thus achieving a protective effect for the deep groove ball bearing.

[0012] In addition, the mushroom-shaped outer column and the arc-shaped outer connecting hole cooperate to connect the protective outer plate and the bearing outer ring by rotation and snap-fit, making assembly easier. When the mushroom-shaped outer column is located at the end with the smaller diameter of the arc-shaped outer connecting hole, the outer fixed hole and the external thread blind hole are in a connected state. Tighten the outer bolt so that the end of the outer bolt is connected in the external thread blind hole, ensuring the firmness of the connection between the protective outer plate and the bearing outer ring.

[0013] In addition, the mushroom-shaped inner column and the arc-shaped inner connecting hole cooperate to connect the protective inner plate and the bearing inner ring by rotation and snap-fit, making assembly easier. When the mushroom-shaped inner column is located at the end with the smaller diameter of the arc-shaped inner connecting hole, the inner fixed hole and the internal thread blind hole are in a connected state. Tighten the inner bolt so that the end of the inner bolt is connected in the internal thread blind hole, ensuring the firmness of the connection between the protective inner plate and the bearing inner ring.
