[0002] A cam bearing follower is assembled from rod ends, rolling elements, and an outer ring as its main components. As a driven bearing used in cam mechanisms and linear motion, the cam bearing follower has high rigidity and high precision, and is widely used in machine tools, industrial robots, electronic components, and office automation equipment.

[0003] When used in welding logistics carts, cam followers are high-speed rotating components and currently suffer from the following drawbacks: The cam follower uses a simple rubber sealing ring, which, during long-term operation, ages and cracks due to mechanical vibration and temperature changes, losing its sealing effect. Furthermore, the cam follower operates in dusty environments with many foreign objects. Under high-speed operation, external dust particles can easily enter the interior, leading to insufficient lubrication, accelerated wear of internal parts, and a significant reduction in the cam follower's lifespan, increasing equipment maintenance costs.

[0024] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0025] A cam follower with a dustproof sealing cover, see reference Figure 1 The system includes a cam follower body 10 and a dustproof front cover 20 located on one end face of the cam follower body 10. The dustproof front cover 20 is tightly fitted and fixedly connected to the cam follower body 10. A rubber plug 30 for sealing is provided at the end of the dustproof front cover 20 away from the cam follower body 10, and the rubber plug 30 is inserted into the dustproof front cover 20. A rear end face gasket 40 is provided on the end face of the cam follower body 10 away from the dustproof front cover 20. The rear end face gasket 40 is installed between the cam follower body 10 and the fixing plate of the logistics cart, ensuring a tight connection between the cam follower body 10 and the material cart. Thus, the sealing dustproof front cover 20 between the cam follower body 10 and the rubber plug 30 enhances the sealing performance of the cam follower body 10 and effectively prevents external dust particles from entering.

[0026] Furthermore, referring to Figure 1 and Figure 2The cam follower body 10 includes a cam 11, a bearing 12 disposed within the cam 11, and a connecting guide rod 13 disposed at one end of the bearing 12. The bearing 12 is a roller bearing 12 or a sliding bearing 12, which can roll or slide on the raised surface of the cam 11, converting the motion of the cam 11 into the linear or rotational motion of the bearing 12. The connecting guide rod 13 is located between the bearing 12 and the driven component. In this embodiment, the driven component is a logistics cart, and the connecting guide rod 13 is used to transmit the motion of the bearing 12 to the logistics cart so that the logistics cart follows the movement of the bearing 12.

[0027] Furthermore, referring to Figure 1 and Figure 2 The end of the connecting guide rod 13 away from the bearing 12 is a threaded connection end 131, and a nut 132 is screwed onto the threaded connection end 131. When the cam follower body 10 is connected to the fixed plate of the logistics cart, the connecting guide rod 13 is locked by the nut 132 to achieve a fixed connection between the cam follower body 10 and the logistics cart.

[0028] Furthermore, referring to Figure 1 and Figure 3 The dustproof front cover 20 is located on the end face of the cam 11 away from the connecting guide rod 13. Since the bearing 12 passes through the cam 11, and the end of the bearing 12 away from the connecting guide rod 13 protrudes from the end face of the cam 11, the dustproof front cover 20 covers the outer periphery of the bearing 12 and is welded and fixed to the end face of the cam 11. The outer peripheral edge of the dustproof front cover 20 is welded and fixed to the outer periphery of the bearing 12 using a full weld to ensure the sealing of the bearing 12 and to prevent the bearing 12 from jamming.

[0029] Reference Figure 2 and Figure 3 The dustproof front cover 20 has an end cap hole 21 at its center, which corresponds to the center of the bearing 12. A slot 22 is formed on the side of the dustproof front cover 20 facing the cam 11. The slot 22 and the end cap hole 21 are concentric circles. The slot 22 provides space for the bearing 12 on the end face of the cam 11, and its size and shape are adapted to the size and shape of the bearing 12. When the dustproof front cover 20 is placed on the end face of the cam 11, the bearing 12 is located within the slot 22.

[0030] Furthermore, referring to Figure 2 and Figure 3 The thickness of the dustproof front cover 20 is 3mm, the depth of the end cover hole 21 is 1.5mm, the depth of the slot 22 is 1.5mm, and the thickness of the bearing 12 protruding from the cam 11 is 0.5mm. When the dustproof front cover 20 is placed on the outer periphery of the bearing 12, the bearing 12 is about 1mm away from the bottom of the slot 22, and a cavity 23 is formed between the end face of the bearing 12 and the bottom of the slot 22.

[0031] Furthermore, referring to Figure 3 The cavity 23 between the slot 22 and the bearing 12 is filled with lubricating oil. The lubricating oil in the cavity 23 can lubricate the cam follower body 10 at any time.

[0032] Furthermore, referring to Figure 2 and Figure 3 The rubber plug 30 is located inside the end cap hole 21. The rubber plug 30 extends into the end cap hole 21 from the end of the dustproof front cover 20 away from the cam follower body 10, and is sealed to the inner wall of the end cap hole 21 and fixed by applying glue, so as to achieve the sealing effect of the dustproof front cover 20 on the cam follower body 10.

[0033] Furthermore, referring to Figure 2 and Figure 3 The rear end face gasket 40 is sleeved on the connecting guide rod 13, and the rear end face gasket 40 is installed on the end face of the cam 11 facing the connecting guide rod 13. A through hole 41 is provided at the center of the rear end face gasket 40 for the connecting guide rod 13 to pass through. The size and shape of the through hole 41 are adapted to the size and shape of the connecting guide rod 13. The connecting guide rod 13 passes through the through hole 41 of the rear end face gasket 40 to achieve connection and fixation between the rear end face gasket 40 and the cam 11. A receiving groove 42 is provided on the side of the rear end face gasket 40 facing the cam 11. The receiving groove 42 is opened along the axial direction of the rear end face gasket 40, and the side of the cam 11 facing the rear end face gasket 40 is received within the receiving groove 42.

[0034] Furthermore, referring to Figure 2 and Figure 3 The rear end face gasket 40 has a thickness of 4mm, and the receiving groove 42 has a depth of 2mm, meaning the cam 11 extends 2mm into the rear end face gasket 40. This limits the movement of the cam 11 and reduces the likelihood of collisions caused by direct contact between the cam 11 and the logistics cart. The rear end face gasket 40 is installed between the cam 11 and the fixing plate of the logistics cart, thus improving the service life of the cam follower body 10.

[0035] Furthermore, referring to Figure 2 and Figure 3 The rear end gasket 40 is made of plastic, rubber, or PET material to reduce noise and minimize collisions with the logistics vehicle.

[0036] This invention provides a dustproof front cover 20 on the front end face of the cam follower body 10 to seal the end face of the cam follower body 10, preventing external dust particles from entering the interior of the cam follower body 10 during high-speed operation. A groove 22 is pre-reserved in the dustproof front cover 20 and filled with lubricating oil to lubricate the cam follower body 10 at any time, preventing wear and jamming of internal parts, thus improving the service life of the cam follower body 10 and reducing maintenance costs.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
