Description

Technical Field

[0001] The utility model relates to the technical field of guide wheels, in particular to a guide wheel with a self-lubricating function. Background Art

[0002] The idler wheel is a crucial component of crawler-type equipment, such as excavators and bulldozers. Its primary function is to guide the track's winding correctly, ensuring smooth operation during travel and operation. It is typically mounted at the front of the equipment, opposite the drive wheel.

[0003] The existing guide wheel is lubricated by the lubricating fluid sealed inside when in use. However, the lubricating fluid inside cannot be replenished, resulting in the lubrication effect becoming poor after a long period of use. At the same time, the installation and disassembly of the wheel body is extremely cumbersome, resulting in great inconvenience during installation and maintenance. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a guide wheel with a self-lubricating function, which has the advantages of self-lubrication and easy installation and maintenance, and solves the problems raised by the above-mentioned background technology.

[0005] The cam is fixedly mounted on the wheel shaft, and the cam is fixedly mounted on the wheel shaft, wherein the cam is fixedly mounted on the wheel shaft, and the cam is fixedly mounted on the wheel shaft.

[0006] As a preferred technical solution of the present invention, two guide wheels are provided on the inner wall of the installation rod, and the wire rope is located outside the guide wheels on the inner wall of the installation rod.

[0007] As a preferred technical solution of the present invention, the two ends of the spring 1 overlap the outer wall of the sliding block and the inner wall of the mounting rod 1 respectively, and the outer wall of the sliding block fits the inner wall of the mounting rod 1.

[0008] As an optimal technical solution of the present invention, a circular groove is provided on the top of the fixed shaft, and the sealing head is located inside the circular groove. The bottom of the sealing head fits into the inner wall of the circular groove on the top of the fixed shaft, and the top of the sealing head is provided with an oblique angle.

[0009] As a preferred technical solution of the present invention, a square groove is provided on the outer wall of the insertion block, and the size of the square groove is adapted to the size of the locking block.

[0010] As an optimal technical solution of the present invention, a circular groove is provided on the outer wall of the locking block, and the circular groove passes through the locking block. The screw extends into the circular groove, and the screw and the circular groove on the outer wall of the locking block are in a threaded connection relationship.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The guide wheel with self-lubricating function rotates on the outer wall of the fixed shaft when the equipment moves as a whole, thereby driving the rotating piece on the outer wall of the fixed shaft to rotate. The rotating piece presses the pressure rod downward through the oblique angle of the top of the pressure rod, so that the bottom of the pressure rod enters the inner wall of the fixed shaft. At this time, the interior of the fixed shaft loses pressure, and the sliding block is driven to move through the rebound of the sealing port, thereby causing the sliding block to push the lubricating fluid, which is connected to the pipeline inside the fixed shaft through the mounting rod 1, and squeezes the lubricating fluid into the interior of the fixed shaft. Finally, it is discharged from the circular groove on the top of the fixed shaft to between the wheel body and the fixed shaft to lubricate them.

[0013] 2. The guide wheel with self-lubricating function rotates the screw, so that the screw drives the thread of the outer wall to rotate. At this time, due to the threaded connection between the screw and the inner wall of the locking block, the screw is driven by the locking block and moves linearly along the outer wall of the locking block, thereby separating the locking block from the insertion block. At this time, the second mounting rod can be removed, the wheel body can be removed from the outer wall of the fixed shaft, and after replacing it, the structure can be reset.

An insertion block 16 is fixedly installed at one end of the fixed shaft 2 close to the mounting rod 2 4, and a locking block 15 is slidably connected to the inner wall of the mounting rod 2 4. In the above structure, an extension ring is provided at the bottom of the pressure rod 12, and the diameter of the extension ring is larger than the diameter of the inner wall of the bottom of the fixed shaft 2.

[0022] In a preferred embodiment, two guide wheels are provided on the inner wall of the mounting rod 3, and the wire rope 6 is located outside the guide wheels on the inner wall of the mounting rod 3. In the above structure, the wire rope 6 is protected by the two guide wheels on the inner wall of the mounting rod 3, so that the wire rope 6 will not come into contact with the outer wall of the mounting rod 3.

[0023] In a preferred embodiment, the two ends of the spring 8 overlap the outer wall of the sliding block 7 and the inner wall of the mounting rod 3 respectively, and the outer wall of the sliding block 7 fits the inner wall of the mounting rod 3. In the above structure, the interior of the mounting rod 3 is sealed by installing the sealing port 5. At this time, the sliding block 7 moves toward the sealing port 5, so that the sliding block 7 squeezes the lubricating fluid on the inner wall of the mounting rod 3 and transports it from the inner wall of the fixed shaft 2.

[0024] In a preferred embodiment, a circular groove is provided at the top of the fixed shaft 2, and the sealing head 13 is located inside the circular groove, the bottom of the sealing head 13 fits against the inner wall of the circular groove at the top of the fixed shaft 2, and the top of the sealing head 13 is provided with an oblique angle. In the above structure, the circular groove at the top of the fixed shaft 2 is sealed by the bottom of the sealing head 13. At this time, the rotating piece 11 is driven to rotate by the rotation of the wheel body 1 on the outer wall of the fixed shaft 2. The rotating piece 11 presses the pressure rod 12 downward through the oblique angle at the top of the pressure rod 12, so that the bottom of the pressure rod 12 enters the inner wall of the fixed shaft 2. At this time, the lubricating fluid on the inner wall of the fixed shaft 2 can be discharged through the circular groove at the top of the fixed shaft 2.

[0025] In a preferred embodiment, a square groove is provided on the outer wall of the insertion block 16, and the size of the square groove is adapted to the size of the locking block 15. In the above structure, the locking block 15 is inserted into the square groove on the outer wall of the insertion block 16, so that the locking block 15 fixes the square groove on the outer wall of the insertion block 16, thereby fixing the insertion block 16.

[0026] In a preferred embodiment, a circular groove is provided on the outer wall of the locking block 15, and the circular groove passes through the locking block 15, the screw 14 extends into the circular groove, and the screw 14 and the circular groove on the outer wall of the locking block 15 are threadedly connected. In the above structure, by rotating the screw 14, the screw 14 drives the thread of the outer wall to rotate. At this time, due to the threaded connection between the screw 14 and the inner wall of the locking block 15, the screw 14 is driven by the locking block 15 and moves linearly along the outer wall of the locking block 15.

[0027] Working principle: when using this device, the device is fixed as a whole by installing rod 1 3 and installing rod 2 4. When the device moves as a whole, the wheel body 1 rotates on the outer wall of the fixed shaft 2, driving the rotating piece 11 to rotate. The rotating piece 11 presses the pressure rod 12 downward through the bevel at the top of the pressure rod 12, so that the bottom of the pressure rod 12 enters the inner wall of the fixed shaft 2. At this time, the lubricating fluid on the inner wall of the fixed shaft 2 can be discharged through the circular groove at the top of the fixed shaft 2. At this time, the internal pressure of the fixed shaft 2 is lost, causing the sealing port 5 to rebound, driving the sliding block 7 to move, and then causing the sliding block 7 to push the lubricating fluid through the same pipeline inside the installing rod 1 3 and the fixed shaft 2. The lubricating liquid is squeezed into the interior of the fixed shaft 2 and finally discharged from the circular groove on the top of the fixed shaft 2 to between the wheel body 1 and the fixed shaft 2 to lubricate it, thereby achieving the effect of self-lubrication of the equipment. When the wheel body 1 needs to be replaced, the screw 14 is rotated to drive the screw 14 to rotate the thread of the outer wall. At this time, due to the threaded connection between the screw 14 and the inner wall of the locking block 15, the screw 14 is driven by the locking block 15 to make a linear motion along the outer wall of the locking block 15, thereby disengaging the locking block 15 from the insertion block 16. At this time, the mounting rod 24 can be removed, the wheel body 1 can be removed from the outer wall of the fixed shaft 2, and after replacing it, the structure can be reset.
