Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a centrifugal bearing oil-throwing device based on a built-in oil passage. Background Technology

[0002] As a type of gear, bevel gears are mostly machined by milling. To ensure machining accuracy, lubricating oil or coolant needs to be sprayed onto the surface of the bevel gear during the milling process to reduce the impact of the temperature generated during milling on the tooth profile.

[0003] However, after the bevel gears are machined, a lot of lubricating oil or coolant adheres to their surface and inner bore. For convenient storage, this lubricating oil or coolant generally needs to be removed. Currently, in addition to manual cleaning, oil removal on bevel gears is also done using oil-throwing devices. These devices use the centrifugal force generated by the rotating bevel gears to throw off the lubricating oil adhering to the gears. However, existing oil-throwing devices are basically only effective for oil adhering to the outer surface of bevel gears with shafts. For bevel gears without shafts but with large shaft holes, existing oil-throwing devices are difficult to clean the oil from the inner bore of the bevel gears. Manual cleaning, on the other hand, is inefficient. Utility Model Content

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] like Figures 1-4 The centrifugal bearing oil-throwing device based on built-in oil channels shown has a frame 1. Adjustable height supports are installed at the four corners of the bottom surface of the frame 1. An oil baffle box 25 is fixed to the upper left side of the frame 1. A frame plate 2 is fixed to the bottom surface of the oil baffle box 25. A mounting seat 9, penetrating the frame plate 2 vertically, is fixed to the frame plate 2. A reduction motor 11 is fixed to the bottom surface of the mounting seat 9. A bearing seat 10 is provided inside the mounting seat 9. A deep groove ball bearing is installed in the upper part of the bearing seat 10, and a tapered roller bearing is installed in the lower part. A rotating shaft 3 is rotatably mounted inside the inner rings of the deep groove ball bearing and the tapered roller bearing. The lower end of the rotating shaft 3 is connected to the reduction motor 11 for transmission. A transition plate 12 is fixed to the upper end face of the rotating shaft 3. A pneumatic chuck 4, which rotates synchronously with the rotating shaft 3, is installed on the transition plate 12. The pneumatic chuck 4 has three soft claw pads 5 evenly distributed circumferentially and moving radially to clamp the bevel gear.

[0023] A rectangular hole is provided on the frame plate 2 located on the front side of the mounting base 9. An oil receiving tray 7 is installed on the frame 1 below the frame plate 2. The bottom surface of the oil receiving tray 7 is composed of two inclined plates spliced ​​together, and an oil outlet pipe 15 is fixedly connected at the splice of the two inclined plates. A filter box 13 is fixed on the bottom surface of the frame plate 2. A removable filter box 14 is installed in the filter box 13. A cleaning box 8 is provided in the frame 1 below the oil receiving tray 7. When the bevel gear rotates synchronously with the rotating shaft 3, the oil adhering to the outer surface of the bevel gear is thrown off onto the frame plate 2 under the action of centrifugal force. Then, it flows into the filter box 13 through the rectangular hole, is filtered by the filter box 14, flows into the oil receiving tray 7, flows along the inclined plate of the oil receiving tray 7 to the oil outlet pipe 15, and finally drips into the cleaning box 8.

[0024] The rotating shaft 3 has an oil passage 6 that communicates with the inner hole of the bevel gear. The oil passage 6 includes a stepped hole 6-1 that is larger at the top and smaller at the bottom. The larger hole at the top of the stepped hole 6-1 is connected to the inner hole of the pneumatic chuck 4. A horizontal hole 6-2 is provided on the rotating shaft 3 at the lower end of the stepped hole 6-1. The smaller hole at the lower end of the stepped hole 6-1 is connected to the horizontal hole 6-2. The mounting base 9 has an inner cavity with the bottom surface inclined to the outside. The outlet end of the horizontal hole 6-2 is connected to the inner cavity of the mounting base 9. An oil drain pipe 16 is connected to the outer side of the bottom surface of the inner cavity of the mounting base 9. When the bevel gear rotates synchronously with the rotating shaft 3, the oil adhering to the inner hole of the bevel gear slides down the inner hole of the bevel gear, flows into the oil passage 6 through the inner hole of the pneumatic chuck 4, flows into the inner cavity of the mounting base 9 from the horizontal hole 6-2 of the oil passage 6, and finally falls into the oil receiving pan 7 through the oil drain pipe 16.

[0025] As the oil removal operation continues, more and more oil accumulates in the cleaning box 8. In order to detect the oil level in the cleaning box 8 in a timely manner, a detection mechanism for detecting the oil level in the cleaning box 8 is provided on the side of the cleaning box 8.

[0026] like Figure 5 As shown, the detection mechanism includes a float 17, a detection box 18, a detection rod 19, a detection plate 20, and a proximity switch 21. One side of the detection box 18 communicates with the cleaning box 8. The float 17 is located inside the detection box 18. The lower end of the detection rod 19 is connected to the float 17. A detection bracket 22 is fixed to the upper surface of the detection box 18. A guide sleeve 23 that slides with the detection rod 17 is fixed to the center of the detection bracket 22. A channel steel-shaped guide frame 24 is fixed to the upper surface of the detection bracket 22. The detection plate 20 includes a right-angle plate and a guide plate. The horizontal part of the right-angle plate is fixed to the upper end of the detection rod 17. The guide plate slides with the side plates of the guide frame 24. The proximity switch 21 is installed on the inner wall of the side plate of the guide frame 24 corresponding to the vertical part of the right-angle plate. As the oil level in the cleaning box 8 rises, it pushes the float 17 to rise. When the right-angle plate of the detection plate 20 is sensed by the proximity switch 21, it indicates that the oil level in the cleaning box 8 is about to be full and needs to be addressed.

[0027] The oil baffle 25 is provided with an upper spray pipe 26 blowing towards the upper side of the bevel gear and a lower spray pipe 27 blowing towards the lower side of the bevel gear on the inner walls of the left and right sides respectively. By spraying high-pressure gas onto the bevel gear through the upper spray pipe 26 and the lower spray pipe 27, the oil on the outer surface of the bevel gear can be quickly dripped downwards.

[0028] The frame 1 is covered with protective plates on all sides. The oil slinging operation is carried out in the oil baffle 25 on the left side of the frame 1, wherein the attached Figure 1 In the middle, the protective plate on the front of the frame 1 has been removed to facilitate the display of the internal installation structure; the upper right side of the frame 1 is used to set up the control box to control the operation of the oil throwing device. At the same time, a cover plate is set on the upper end face of the frame 1 using a slider guide mechanism. When the oil throwing device is working, the cover plate is slid up to the oil tank 25 to prevent oil from being thrown out and to ensure operational safety.
