Description
Technical Field
[0001] The utility model relates to the technical field of lubrication mechanisms, in particular to a track wheel floating oil seal lubrication mechanism for crawler-type engineering machinery. Background Art
[0002] The lubrication mechanism of the floating oil seal of the track roller for crawler engineering machinery is an efficient and reliable lubrication system, which is used to pre-lubricate the floating oil seal before the track roller is assembled. This mechanism usually includes a positioning plate. The floating oil seal is placed in the circular groove on the surface of the positioning plate and positioned. The operator then directly delivers the lubricating oil to the friction contact point of the floating oil seal, which ensures that the oil seal is fully lubricated before the track roller starts working, reducing wear during initial operation.
[0003] At present, the existing lubrication mechanism for the floating oil seal of the supporting wheel usually adopts a customized positioning mechanism to position the floating oil seal. The positioning mechanism is cut from a piece of metal plate as a whole. When in use, it is only necessary to put the floating oil seal into the circular groove at the center of the inner portion thereof, and the positioning is achieved by matching the inner diameter of the circular groove. However, since the entire device is cut from a piece of metal plate, the existing device is prone to wear during long-term use, thereby affecting the positioning accuracy. In addition, the matching degree between the inner diameter of the circular groove and the floating oil seal is extremely high. Once wear occurs, it is easy to cause the existing device to inaccurately position the floating oil seal, causing the floating oil seal to fall off during the lubrication process. In view of this, we provide a lubrication mechanism for the floating oil seal of the supporting wheel of crawler engineering machinery. Utility Model Content

[0021] 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.
[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a floating oil seal lubrication mechanism for a track-type engineering machinery supporting wheel, comprising a lubricating device 1, a disc 2 is rotatably connected to the inner center of the lubricating device 1, and a positioning support 201 is fixedly connected to the top of the disc 2, the positioning support 201 is located in the inner center of the lubricating device 1, and the positioning support 201 is rotatably connected to the inner center of the lubricating device 1, two groups of corresponding positioning fixtures 202 are slidably connected to the top surface of the positioning support 201 at the same time, and a small motor 203 is fixedly connected to the bottom end of the positioning support 201, both sides of the inner wall of the positioning fixture 202 are slidably connected to one side of the inner part of the positioning support 201 through the output end of the small motor 203, a telescopic cylinder 3 is fixedly connected to one side of the outer wall of the lubricating device 1, and a group of corresponding limit frames 301 are fixedly connected to both sides of the inner part of the lubricating device 1 at the same time, a sliding frame 302 is slidably connected to one side of the inner part of the lubricating device 1 through the telescopic cylinder 3 and the limit frame 301, and the outer wall center of the sliding frame 302 is fixedly connected to the outer wall of the telescopic end of the telescopic cylinder 3.
[0023] The operator first places the floating oil seal at the center of the top surface of the positioning support 201, and then activates the small motor 203, which drives the screw 205 to rotate inside the positioning support 201 by meshing the gears between the driving teeth 204 and the screw 205. In order to ensure the precise movement of the positioning fixture 202, the positioning support 201 is equipped with a plurality of guide frames 206, which penetrate one side of the interior of the positioning fixture 202, and are limited to the positioning fixture 202 by slidingly connecting the inner side of the positioning fixture 202 with the outer wall of the guide frame 206, which makes the positioning fixture 202 When moving, it can only slide horizontally along the outer wall of the guide frame 206. With the drive of the driving teeth 204, multiple threaded screws 205 rotate successively, and use the threads on their outer walls to push multiple positioning fixtures 202 on the top surface of the positioning support 201 to move toward the outer wall of the floating oil seal along the outer wall of the guide frame 206 at the same time. When the outer wall of the positioning fixture 202 conflicts with the outer wall of the floating oil seal, the floating oil seal is accurately fixed at the center of the top surface of the positioning support 201. Subsequently, the telescopic cylinder 3 is started, so that its telescopic end pushes the sliding frame 302 and the lifting support 303 to slide along the outer wall of the limiting frame 301 toward the side of the floating oil seal. When the sliding frame 302 After the lifting support 303 reaches the specified position, the operator starts to rotate the adjustment knob 307. Since the inner side of the lifting support 303 is fixedly connected to the lifting frame 304, and the lifting frame 304 is located on the inner side of the lubrication frame 305, the operator can accurately control the position of the lubrication frame 305 and the lubrication rod 306 by rotating the adjustment knob 307. As the adjustment knob 307 is gradually rotated, the lubrication frame 305 and the lubrication rod 306 move vertically downward along the outer wall of the lifting frame 304. Once the lubrication rod 306 reaches the appropriate position, the operator will activate the telescopic cylinder 3 again. The function of the telescopic cylinder 3 is to pull the sliding frame 304 to move. 02, make the lubricating rod 306 close to the inner wall of the floating oil seal, so that when the lubricating device 1 drives the disc 2 to rotate, the lubricating rod 306 can effectively lubricate the friction part of the inner wall of the floating oil seal, thereby driving the disc 2 to rotate through the lubricating device 1, so that the lubricating rod 306 lubricates the friction part of the inner wall of the floating oil seal, and ensures that the lubricant can be evenly coated on the entire inner wall of the floating oil seal, which greatly improves the lubrication efficiency and quality. The device reduces manual intervention in the lubrication process and reduces labor intensity. At the same time, it also improves the accuracy and safety of the operation, ensuring that the installation and maintenance of the floating oil seal are efficient and convenient.
[0024] like Figure 1-3As shown, multiple guide frames 206 are fixedly connected to both sides of the inner wall of the positioning support 201, and the guide frames 206 are located on both sides of the interior of the positioning fixture 202. One end of the outer wall of the guide frame 206 is connected to the bottom side of the positioning fixture 202 through one end, and the inner side of the positioning fixture 202 is slidably connected to the outer wall of one side of the guide frame 206. Multiple guide frames 206 are fixedly connected to both sides of the inner wall of the positioning support 201, and the guide frames 206 are located on both sides of the interior of the positioning fixture 202. The outer wall of the guide frame 206 One end is connected through one side of the bottom of the positioning fixture 202, and the inner side of the positioning fixture 202 is slidably connected to the outer wall of one side of the guide frame 206, the threaded screw 205 is located at the inner bottom end of the positioning fixture 202, and the positioning fixture 202 is slidably connected to the inner side of the positioning support 201 through the threaded screw 205, the outer wall of the top end of the threaded screw 205 is connected through the inner bottom end of the positioning fixture 202, and the top of the outer wall of the threaded screw 205 is rotatably connected to the inner bottom end of the positioning fixture 202 through a thread.
[0025] First, place the floating oil seal at the center of the top surface of the positioning support 201, then activate the small motor 203, and drive the driving gear 204 through the small motor 203, so that the threaded screw 205 is driven to rotate inside the positioning support 201 through gear meshing. Since a plurality of guide frames 206 are provided inside the positioning support 201, and the guide frames 206 penetrate one side of the inside of the positioning fixture 202, the positioning fixture 202 is limited by sliding between the inner side of the positioning fixture 202 and the outer wall side of the guide frame 206, so that the positioning fixture 202 can only slide horizontally along the outer wall of the guide frame 206 when moving. As the plurality of threaded screws 205 inside the positioning support 201 rotate successively under the drive of the driving gear 204, the positioning support 2 01 Through the threads provided on the outer wall of the threaded screw 205, multiple positioning fixtures 202 on the top surface of the positioning support 201 are driven to move simultaneously along the outer wall of the guide frame 206 toward the outer wall of the floating oil seal, and the floating oil seal is fixed at the center of the top surface of the positioning support 201 through the outer wall of the positioning fixture 202 contacting the outer wall of the floating oil seal. Therefore, through the precise cooperation between the driving teeth 204, the threaded screw 205 and the guide frame 206, the positioning fixture 202 can quickly and accurately fix the floating oil seal at the center of the top surface of the positioning support 201, and the device can not only perform positioning work on floating oil seals of different sizes, but also effectively prevent wear caused by long-term use, avoid the reduction of positioning accuracy, and cause the floating oil seal to fall off during the lubrication process.
[0026] like Figure 1 , Figure 4 and Figure 5As shown, the outer wall at the top of the sliding frame 302 is fixedly connected to the lifting support 303, and the lifting frame 304 is fixedly connected to the inner side of the lifting support 303, the inner center of the lifting support 303 is slidably connected to the lubrication frame 305 through the lifting frame 304, and the bottom end of one side of the lubrication frame 305 is fixedly connected to the lubrication rod 306, the outer wall of one side of the lifting frame 304 is connected with the inner side of the lubrication frame 305 through, and the inner side of the lubrication frame 305 is slidably connected to the lifting frame 304, the inner side of the lifting support 303 is rotatably connected to the adjusting knob 307, and one end of the outer wall of the adjusting knob 307 is rotatably connected to the inner side of the lubrication frame 305 through gear meshing.
[0027] After the floating oil seal is fixed to the top surface of the positioning support 201 by the positioning fixture 202, the telescopic cylinder 3 is activated so that its telescopic end pushes the sliding frame 302 and the lifting support 303 to slide along the outer wall of the limiting frame 301 toward the side close to the floating oil seal. Then, the operator turns the adjusting knob 307. Since the lifting frame 304 is fixedly connected to the inner side of the lifting support 303, and the lifting frame 304 is located at the inner side of the lubrication frame 305, the lifting frame 304 passes through the inner side of the lubrication frame 305 and makes the inner side of the lubrication frame 305 slidably connected to the outer wall side of the lifting frame 304, so that the lifting frame 304 limits the movement of the lubrication frame 305. As the operator gradually turns the adjusting knob 307, the adjusting knob 307 drives the lubrication frame 305 through the gear transmission. After the lubricating rod 306 moves vertically downward along the outer wall of the lifting frame 304, the telescopic cylinder 3 is activated again. After the lubricating rod 306 is pressed against the inner wall of the floating oil seal by pulling the sliding frame 302 through the telescopic cylinder 3, the disc 2 is driven to rotate through the lubricating device 1, so that the lubricating rod 306 lubricates the friction part of the inner wall of the floating oil seal, thereby driving the disc 2 to rotate through the lubricating device 1, so that the lubricating rod 306 lubricates the friction part of the inner wall of the floating oil seal, and ensures that the lubricant can be evenly coated on the entire inner wall of the floating oil seal, which greatly improves the lubrication efficiency and quality, so that the device reduces manual intervention in the lubrication process, reduces labor intensity, and also improves the accuracy and safety of the operation, ensuring that the installation and maintenance of the floating oil seal are efficient and convenient.
[0028] The working principle of the utility model is as follows: the operator first places the floating oil seal at the center of the top surface of the positioning support 201, and then activates the small motor 203, which drives the threaded screw 205 to rotate inside the positioning support 201 by meshing the gears between the driving teeth 204 and the threaded screw 205. In order to ensure the precise movement of the positioning fixture 202, the positioning support 201 is equipped with a plurality of guide frames 206, which penetrate one side of the interior of the positioning fixture 202, and are limited to the positioning fixture 202 by slidingly connecting the one side of the interior of the positioning fixture 202 with one side of the outer wall of the guide frame 206, so that the positioning fixture 202 can only slide horizontally along the outer wall of the guide frame 206 when moving;
[0029] With the driving of the driving teeth 204, the multiple threaded screws 205 rotate successively, and use the threads on their outer walls to push the multiple positioning fixtures 202 on the top surface of the positioning support 201 to move toward the outer wall of the floating oil seal along the outer wall of the guide frame 206 at the same time. When the outer wall of the positioning fixture 202 contacts the outer wall of the floating oil seal, the floating oil seal is accurately fixed at the center of the top surface of the positioning support 201;
[0030] Subsequently, the telescopic cylinder 3 is started, so that its telescopic end pushes the sliding frame 302 and the lifting support 303 to slide along the outer wall of the limiting frame 301 toward the floating oil seal. When the sliding frame 302 and the lifting support 303 reach the specified position, the operator starts to turn the adjusting knob 307. Since the inner side of the lifting support 303 is fixedly connected to the lifting frame 304, and the lifting frame 304 is located at the inner side of the lubrication frame 305, the operator can accurately control the position of the lubrication frame 305 and the lubrication rod 306 by turning the adjusting knob 307.
[0031] As the adjusting knob 307 is gradually turned, the lubrication rack 305 and the lubrication rod 306 move vertically downward along the outer wall of the lifting rack 304. Once the lubrication rod 306 reaches the appropriate position, the operator will activate the telescopic cylinder 3 again. This time, the telescopic cylinder 3 is used to pull the sliding rack 302 so that the lubrication rod 306 is close to the inner wall of the floating oil seal. In this way, when the lubrication device 1 drives the disc 2 to rotate, the lubrication rod 306 can effectively lubricate the friction part of the inner wall of the floating oil seal, thereby driving the disc 2 to rotate through the lubrication device 1, so that the lubrication rod 306 lubricates the friction part of the inner wall of the floating oil seal and ensures that the lubricant can be evenly coated on the entire inner wall of the floating oil seal.
