Description

Technical Field

[0001] This utility model relates to the field of mining and building materials equipment technology, and in particular to a dry oil atomizing spray frame installation and positioning device. Background Technology

[0002] To ensure the smooth operation of low-speed, heavy-duty gear transmission systems such as ball mills, semi-autogenous mills, and rotary kilns, dry oil injection lubrication systems are typically used to directionally spray particulate grease mist onto the gears, forming a lubricating film on the meshing tooth surfaces. This reduces tooth surface friction and improves the smoothness and service life of the gear transmission system. The atomizing nozzle is the main component for directional grease mist injection, and multiple nozzles are usually fixed to the inner wall of the gear housing using an atomizing spray frame. However, existing atomizing spray frames are mainly installed by welding, which presents maintenance difficulties when nozzle blockage requires disassembly and cleaning. If disassembly is done by gas cutting or other cutting methods, cutting slag and iron filings may fall into the lower oil sump, causing oil contamination. Furthermore, reinstalling the atomizing spray frame requires repositioning to adjust the optimal nozzle spray angle and position, resulting in labor-intensive and time-consuming installation and debugging. Therefore, these issues significantly impact the maintenance of dry oil injection lubrication systems in actual use. Utility Model Content

The inner hole of the left gear cover 7 is fitted onto the right side of the sliding rod 2 and is fixed to the flange of the positioning flange 3 by bolts. The inner hole of the right gear cover 7 is fitted onto the reduced diameter section of the sliding flange 1 and is fixed to the flange of the sliding flange 1 by bolts. Multiple nozzles 14 are fixed along the length of the dry oil atomizing spray frame. The oil pipes on the multiple nozzles 14 are respectively located in the inner hole of the sliding flange 1 through a fixed joint 15.

[0020] Specifically, a stepped hole 8 is provided on the inner left side of the positioning flange 3, and a ball bearing 5 is fitted into the stepped hole 8.

[0021] Specifically, the ball bearing 5 and the slide rod 2 are in clearance fit with a clearance of 0.05mm. Anti-friction grease is applied to the inner surface of the ball bearing 5. After applying anti-friction grease through the 0.05mm gap, the slide rod 2 can be positioned relatively stably within the ball bearing 5 and can move smoothly axially.

[0022] Specifically, one end of the slide rod 2 is provided with a countersunk hole 12, and the mounting post at one end of the dry oil atomizing spray frame is fixedly connected in the countersunk hole 12. The mounting post and the countersunk hole 12 are interference fit. The other end of the slide rod 2 is provided with a columnar handle 11. The surface of the handle 11 is pressed with a mesh anti-slip texture. Three through holes 10 are provided at intervals along the length of the slide rod 2, with a spacing of 10-20mm. The positioning pin 4 passes through the through hole 9 on the outer circular surface of the positioning flange 3 and the through hole 10 on the slide rod 2 to fix the rotation angle of the slide rod 2. The sum of the length of the slide rod 2 and the length of the atomizing spray frame is greater than 10-15% of the width of the gear cover 7.

[0023] Specifically, three annular grooves 13 are evenly spaced on the inner hole of the sliding flange 1. The fixed joint 15 is slidably disposed in the inner hole of the sliding flange 1. The inner diameter of the sliding flange 1 is 0.05 mm larger than the outer diameter of the fixed joint 15. Anti-friction grease is applied to the inner hole of the sliding flange 1 and injected into the annular grooves 13. With the help of the 0.05 mm gap, a lubricating oil film is formed between the inner wall of the sliding flange 1 and the outer wall of the fixed joint 15, ensuring smooth movement of the slide rod and the dry oil atomizing spray frame.

When installing the atomizing spray frame 6, slide the slide rod 2 at the left end of the atomizing spray frame 6 into the inner hole of the positioning flange 3, and slide the fixed joint 15 at the right end of the atomizing spray frame 6 into the inner hole of the sliding flange 1 to complete the installation. In use, by rotating the handle 11 of the slide bar 2, as shown in the attached... Figure 1As indicated by the arrow above, turn the atomizing nozzle of nozzle 14 towards the meshing point of the large and small gears. Adjust the position of nozzle 14 by pulling and pushing the handle to align nozzle 14 with the gear contact surface and ensure that the grease mist fully covers the gear contact surface. After determining the appropriate angle and position, insert the positioning pin 4 into the through hole 9 on the outer circular surface of the positioning flange 3 and the corresponding through hole 10 on the slide rod 2 to lock the slide rod and complete the installation and positioning of the atomizing spray frame 6. When disassembling and maintaining nozzle 14, the positioning pin 4 needs to be pulled out, and the atomizing spray frame 6 and slide rod 2 need to be removed. Then, clean and maintain nozzle 14, valves, etc. After maintenance, repeat the above installation steps to complete the installation.
