Description

Technical Field

[0001] This utility model relates to the field of bearing cleaning technology, and more specifically to a bearing pretreatment cleaning device. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. As bearings are used for a longer period of time, grease, debris, and other contaminants will accumulate on their surface, affecting the normal operation and service life of the bearings. Therefore, regular cleaning of bearing components can effectively extend the service life of the bearings.

[0003] A search revealed Chinese patent CN219253474U, which discloses an intelligent bearing cleaning device. The device includes a cleaning tank with a fixed plate on its outer side and a water tank fixed to the upper side of the fixed plate. A water pump is installed on the outer side of the water tank, and the pump's suction end is connected to the interior of the water tank. The device also includes a cleaning mechanism and a reciprocating movement mechanism. When the drive motor is switched on, a rotating shaft rotates. Through the meshing of a first gear and multiple second gears, multiple rotating shafts rotate in opposite directions. This reverse rotation improves the cleaning effect of multiple brushes on multiple bearing bodies. Simultaneously, a stop rod allows the sliding sleeve to rotate and reciprocate, further improving the cleaning effect. A rubber sleeve effectively prevents collisions between bearing bodies, solving the problem of impacts during cleaning of existing bearing bodies. However, based on existing technology and this device, it was found that the device requires multiple rubber rings to limit the bearing position during installation, which is cumbersome. Utility Model Content

[0004] This utility model provides a bearing pretreatment cleaning device, which has the advantages of avoiding impact during bearing cleaning and eliminating the need to install limiting rubber rings to limit the movement between multiple bearings.

[0005] A bearing pretreatment cleaning device includes a cylinder, a core of which is rotatably connected to a spindle, a motor II for driving the spindle to rotate is fixedly connected to the cylinder, a brush roller and a rotating frame are fixedly connected to the motor II located inside the cylinder, and multiple rotating shafts capable of planetary rotation around the axis of the spindle are rotatably connected to the rotating frame. The brush roller has multiple annular grooves vertically opened, and bearings sleeved on the multiple rotating shafts can be inserted into the corresponding grooves.

[0006] A central gear is fixedly connected to the spindle, and planetary gears that mesh and drive with the central gear are fixedly connected to multiple rotating shafts. The multiple planetary gears mesh and drive with the inner side of the gear ring. Side frames are fixedly connected to both ends of the gear ring, and both side frames are cylindrically installed inside the cylinder. Attached Figure Description

Detailed Implementation

[0010] See Figures 1 to 5 The diagram shows an embodiment of the present invention that improves the comprehensiveness of bearing cleaning. A bearing pretreatment cleaning device includes a cylinder 101, a spindle 201 rotatably connected to the core of the cylinder 101, a motor II 202 for driving the spindle 201 to rotate fixedly on the cylinder 101, a brush roller 203 and a rotating frame 205 are fixedly connected from top to bottom on the motor II 202 located inside the cylinder 101, a plurality of rotating shafts 301 that can rotate planetarily around the axis of the spindle 201 are rotatably connected on the rotating frame 205, a plurality of annular grooves 204 are vertically formed on the brush roller 203, and bearings sleeved on the plurality of rotating shafts 301 can be inserted into the corresponding grooves 204; Multiple bearings are respectively fitted onto the rotating shaft 301. Since the brush roller 203 is made of bristle material, when the bearing slides downward along the axis of the rotating shaft 301, the bearing squeezes the bristles on the brush roller 203, causing the bristles to deform. Therefore, the bearing can be pushed downward to insert into the appropriate groove 204. The groove 204 then acts as an axial limiter for the bearing, allowing each bearing to be inserted and remain in its corresponding groove 204. The design of the groove 204 not only avoids impact during bearing cleaning but also eliminates the need for limiting the bearings on the same rotating shaft 301 using limiting rings or similar parts. Similarly, it also eliminates the need to install multiple rubber limiting rings, saving time.

[0011] Then, the cleaning agent is added into the cylinder 101, and the motor II 202 is started to drive the brush roller 203 on the spindle 201 to rotate, which brushes the bearings on the multiple rotating shafts 301. At this time, the multiple rotating shafts 301 are controlled to perform planetary motion around the axis of the spindle 201. The multiple rotating shafts 301 drive the bearings to perform circular motion around the axis of the spindle 201 while also rotating on their own axis, so that the outer side of the bearings can also be brushed, thus improving the cleaning effect of the bearings.

[0012] Furthermore, the bristles on the brush roller 203 are oriented towards the groove 204, which allows both the upper and lower sides of the bearing to contact the bristles on the brush roller 203. The contact between the outer circumferential surface of the bearing and the inner side of the groove 204 can also clean the oil stains on the outer ring of the bearing, further improving the comprehensiveness of the bearing cleaning effect.

[0013] A drain pipe 102 is fixedly connected to the bottom surface of the cylinder 101 to facilitate the discharge of cleaning agent from the cylinder 101.

[0014] See Figures 3 to 5 The diagram shows a schematic representation of an embodiment of the present invention that drives the bearing to rotate. A central gear 206 is fixedly connected to the spindle 201. Planetary gears 302 that mesh and drive with the central gear 206 are fixedly connected to multiple rotating shafts 301. Multiple planetary gears 302 are meshed and driven with the inner side of the gear ring 303. Side frames 304 are fixedly connected to both ends of the gear ring 303. Both side frames 304 are installed inside the cylindrical body 101. When the spindle 201 rotates, it drives the rotating frame 205 to rotate synchronously. The rotating frame 205 drives multiple rotating shafts 301 to make circular motion around the axis of the spindle 201. At the same time, the planetary gear 302 is connected to the central gear 206 and the gear ring 303 through meshing transmission, which drives the rotating shafts 301 to make circular motion around the axis of the spindle 201 while also rotating on their own axis. Therefore, the bearings on the multiple rotating shafts 301 can both make circular motion around the brush roller 203 and rotate on their own axis, so that the inner and outer sides of the bearings can contact the brush roller 203, which can achieve a more comprehensive cleaning effect on the bearings.

[0015] See Figure 2 , 4 Figures 5 and 6 show schematic diagrams of an embodiment of the present invention that facilitates the removal of the bearing; A guide rod 103 is fixedly connected to the inner wall of the cylinder 101, and one of the side frames 304 is slidably connected to the guide rod 103; two collars 305 are symmetrically fixedly connected to the gear ring 303. A lead screw 104 is rotatably connected inside the cylinder 101. Another side frame 304 is connected to the threaded transmission rod of the lead screw 104. A motor I 105 that drives the lead screw 104 to rotate is fixed to the bottom surface of the cylinder 101. The lower end of the lead screw 104 passes through the cylinder 101 and is connected to the output shaft of the motor I 105 through a coupling. Motor I 105 starts, driving the lead screw 104 to rotate. The lead screw 104, through threaded transmission with the side frame 304, drives the gear ring 303 to move upward. The gear ring 303 disengages from multiple planetary gears 302 and then drives the collar 305 to move upward. Similarly, the bristles can deform, so the collar 305 can push the bearings on the rotating shaft 301 to move upward in sequence, so that multiple cleaned bearings are pushed upward to the opening of the cylinder 101 for easy removal. Secondly, because the thread has self-locking properties, the rotating shaft 301 can stop at a designated position after driving the gear ring 303 upward, facilitating the sequential removal of the bearings.

[0016] The rotating shaft 301 passes through the collar 305. This allows the collar 305 to make uniform contact with the bearing from below, thereby evenly pushing the bearing upwards with force. This makes the upward pushing process of the bearing smoother and avoids uneven force that could cause jamming or damage to the bearing.

[0017] Furthermore, the cylinder body 101 is covered with a cylinder cover 401 to prevent cleaning agent from splashing out when cleaning the bearing.

[0018] The inner side of the cylinder cover 401 is fixedly connected to a bushing 402 that can be inserted into the spindle 201; it provides auxiliary support and limit for the upper end of the spindle 201 to prevent the spindle 201 from swaying when rotating.

[0019] The bottom surface of the cylinder cover 401 is provided with an annular groove 403 into which the rotating shaft 301 can be inserted; it provides auxiliary support and guides the upper end of the rotating shaft 301 to prevent the rotating shaft 301 from rotating on its own or swaying when making circular motion.

[0020] The bottom surface of the cylinder cover 401 is formed with a raised edge larger than the diameter of the cylinder body 101; the two sides of the raised edge are easy to move the cylinder cover 401 by hand.
