DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1-4As shown, the utility model provides a lubricating structure for a screw chiller bearing, comprising an immersion box 1, a filter plate 11 is arranged on the top of the immersion box 1, and evenly distributed empty grooves 111 are opened on the top of the filter plate 11, and the number of the empty grooves 111 is four, and symmetrically distributed clamping rings 12 are arranged above the empty grooves 111, and fixed blocks 13 are fixedly installed on the outer sides of the two clamping rings 12, and fixed rods 14 are fixedly installed on the sides of the two fixed blocks 13 away from the clamping rings 12, and the sides of the two fixed rods 14 away from the fixed blocks 13 are movable Insert rods 15 are inserted, and the ends of the two insert rods 15 away from the fixed rods 14 are respectively fixedly installed with a first stabilizing plate 17 and a second stabilizing plate 18, and the first stabilizing plate 17 and the second stabilizing plate 18 are respectively fixedly connected to the corresponding fixed rods 14 through springs 16. Brackets 19 are fixedly installed on both sides of the top of the filter plate 11, and the first stabilizing plate 17 and the bracket 19 are fixedly connected. A support plate 191 is fixedly installed in the middle of the top of the filter plate 11, and the second stabilizing plate 18 is fixedly connected to the support plate 191. The lower inner wall of the immersion box 1 The surface rotation is penetrated by evenly distributed rotating rods 192, and the number of rotating rods 192 is four. A connecting rod 193 is fixedly installed on the top of the rotating rod 192. In actual use, lubricating oil is added to the immersion box 1, and then the two snap rings 12 are pushed, so that the two snap rings 12 move toward the first stabilizing plate 17 and the second stabilizing plate 18 respectively, so that the insertion rod 15 enters the fixed rod 14, and the spring 16 is deformed at the same time, and then the bearing is placed between the two snap rings 12. At this time, the snap ring 12 is stopped from being pushed, so that the spring 16 releases the pressure and drives the two snap rings 12 to move away from the first stabilizing plate 17 and the second stabilizing plate 18 respectively, thereby limiting the bearing. Then the staff drives the filter plate 11 downward through the bracket 19, so that the bearing is immersed in the lubricating oil. At the same time, the connecting rod 193 passes through the inner ring of the bearing, and drives the rotating rod 192 to rotate, driving the connecting rod 193 to rotate, and the connecting rod 193 drives the inner ring of the bearing to rotate, so that the bearing can be completely immersed in the lubricating oil, thereby improving the subsequent use effect of the bearing.

[0021] A connecting plate 2 is fixedly installed on one side of the top of the immersion box 1, and symmetrically distributed support blocks 21 are fixedly installed on the top of the connecting plate 2. A double-headed screw 22 with opposite threads at both ends rotates through the middle of the two support blocks 21 together, and the outer thread sleeve of the double-headed screw 22 is provided with a symmetrically distributed slider 23. A scraper 24 is fixedly installed on the bottom end of the slider 23, and the scraper 24 is in contact with the filter plate 11.

[0022] By adopting the above technical solution, when the bearing is soaked and the filter plate 11 returns to its original position, the double-headed screw 22 is driven to rotate, which drives the two sliders 23 to move in the same direction. The slider 23 drives the scraper 24 to move, so that the scraper 24 pushes the lubricating oil remaining on the filter plate 11 into the holes on the surface of the filter plate 11, and flows into the soaking box 1 through the holes, so that the residual lubricating oil can be recovered to avoid waste.

[0023] The limiting rod 3 is fixedly mounted on opposite sides of the two supporting blocks 21 , and the limiting rod 3 passes through the two sliding blocks 23 .

[0024] By adopting the above technical solution and providing the limit rod 3, the slider 23 is prevented from deflecting when moving, so that the lubricating oil on the filter plate 11 can be scraped off better.

[0025] A stirring member 4 is provided below the connecting rod 193 , and the stirring member 4 is fixedly sleeved on the outer side of the rotating rod 192 .

[0026] By adopting the above technical solution and providing the stirring member 4, when the rotating rod 192 rotates, the stirring member 4 can be driven to rotate, so that the lubricating oil moves, thereby improving the bearing immersion effect.

[0027] Limiting plates 5 are fixedly installed on both sides of the inner wall of the soaking box 1, and the limiting plates 5 and the filter plates 11 are used in conjunction with each other.

[0028] By adopting the above technical solution and setting the limit plate 5, it is convenient to move the filter plate 11 to the specified position, so that the connecting rod 193 drives the inner ring of the bearing to rotate.

[0029] Mounting plates 6 are slidably provided on both sides of the top of the soaking box 1 , and sliding grooves 61 are provided on both sides of the top of the soaking box 1 close to the mounting plate 6 , and the bottom of the mounting plate 6 is movably clamped in the sliding groove 61 .

[0030] By adopting the above technical solution, by setting the mounting plate 6 and the slide groove 61, the bracket 19 can be supported. When the bracket 19 needs to move down, the mounting plate 6 and the bracket 19 are separated through the slide groove 61, so that the bracket 19 drives the filter plate 11 to descend smoothly.

[0031] A first motor 7 is coaxially fixedly mounted on the bottom of one of the rotating rods 192 , and a second motor 71 is coaxially fixedly mounted on one end of the double-headed screw rod 22 .

[0032] By adopting the above technical solution, by setting the first motor 7, it is convenient to drive the rotating rod 192 to rotate, so that the connecting rod 193 drives the inner ring of the bearing to rotate. By setting the second motor 71, it is convenient to drive the double-headed screw 22 to rotate, so that the residual lubricating oil can be scraped off.

[0033] The four rotating rods 192 are connected to each other through a plurality of belts 8 , and the number of the belts 8 is four.

[0034] By adopting the above technical solution and arranging the belt 8, the four rotating rods 192 can all rotate, thereby improving the soaking efficiency.

[0035] Working principle: In actual use, add lubricating oil to the immersion box 1, and then push the two snap rings 12, so that the two snap rings 12 move toward the first stabilizing plate 17 and the second stabilizing plate 18 respectively, so that the insertion rod 15 enters the fixing rod 14, and the spring 16 is deformed at the same time, and then the bearing is placed between the two snap rings 12. At this time, stop pushing the snap ring 12, so that the spring 16 releases the pressure and drives the two snap rings 12 to move away from the first stabilizing plate 17 and the second stabilizing plate 18 respectively, so as to limit the bearing. Then the staff drives the filter plate 11 downward through the bracket 19, so that the bearing is immersed in the lubricating oil. The connecting rod 193 passes through the inner ring of the bearing, and drives the rotating rod 192 to rotate, thereby driving the connecting rod 193 to rotate, and the connecting rod 193 drives the inner ring of the bearing to rotate, so that the bearing can be completely soaked in the lubricating oil, thereby improving the subsequent use effect of the bearing; when the bearing is soaked and the filter plate 11 returns to its original position, the double-headed screw 22 is driven to rotate, and the two sliders 23 are driven to move in the same direction. The slider 23 drives the scraper 24 to move, so that the scraper 24 pushes the lubricating oil remaining on the filter plate 11 into the holes on the surface of the filter plate 11, and flows into the immersion box 1 through the holes, so that the residual lubricating oil can be recovered to avoid waste.
