[0002] A guide is a device installed before and after the roll pass during the steel rolling process to help the rolled piece enter and exit the roll pass accurately and stably in a predetermined direction and state.

[0003] In recent years, in order to improve the service life of the guide roller shaft, a series of optimization designs have been made on the material of the guide roller shaft, the size of the lower hole, and the depth and width of the oil groove, which has improved the service life of the guide roller shaft to a certain extent. However, the size of the lower hole is still too small and the oil groove is too shallow, which affects the lubrication effect of the bearing. At the same time, the oil hole is easily blocked by debris, which leads to bearing burnout, material deviation, uneven force on the guide roller shaft, and finally causes steel pile-up.

The bearing mechanism 2 includes an outer ring 201 and a connecting frame 202, an inner ring 203 is provided between the outer ring 201 and the connecting frame 202, a sponge ring 204 is provided in the middle of the inner ring 203, a ball 205 is connected to the surface of the connecting frame 202 in a circumferential rotation, a cover plate 206 is provided on the upper part of the inner ring 203, an oil filling hole 207 is provided on one side of the lower surface of the outer ring 201, an oil storage tank 208 is provided inside the outer ring 201, and an oil channel 209 is provided on one side of the inner side of the outer ring 201. An oil guide groove 210 is provided in the middle of the inner wall of the ring 201, a slide groove 213 is provided inside the outer ring 201, a protrusion 211 is slidably connected to one side of the inner wall of the outer ring 201, a wedge block 212 is fixedly connected to one side of the protrusion 211, the outer wall of the wedge block 212 is slidably connected to the inside of the outer ring 201, a slider 214 is slidably connected to the inner wall of the slide groove 213, a wedge groove 215 is provided on one side of the slider 214, a piston 216 is fixedly connected to the bottom end of the slider 214, the outer wall of the piston 216 is slidably connected to the inner wall of the oil passage 209, a spring 217 is fixedly connected to the top end of the slider 214, and one end of the spring 217 is fixedly connected to the inner side of the slide groove 213;

[0019] During the rotation of the bearing mechanism 2, the roller will also rotate. When the roller rotates to the protrusion 211, it will squeeze the protrusion 211, thereby moving the wedge block 212 inward, so that the wedge block 212 is inserted into the wedge groove 215, and the slider 214 will move upward, so that the slider 214 and the piston 216 will be separated from the oil channel 209, and the oil in the oil storage tank 208 will flow from the oil channel 209 into the oil guide groove 210, so that the sponge ring 204 can absorb the lubricating oil and apply it to the ball 205, so that there is enough lubricating oil on the surface of the ball 205, which can be better lubricated when the bearing rotates, thereby ensuring that the shaft body 1 can overcome the problem of easy damage and breakage of the shaft body 1 under the condition of sufficient lubrication effect, and avoid the problem of steel piling due to the breakage of the shaft body 1.

[0020] The lower portion of the inner wall of the outer ring 201 is provided with a placement groove 219;

[0021] By setting up the placement groove 219, solid lubricant is placed inside the placement groove 219. If the lubricant in the oil storage tank 208 is used up and not replenished in time, the placement of the solid lubricant can lubricate the ball 205 when the bearing rotates, thereby achieving the goal that the ball 205 can continue to operate normally without grease on the outside.

[0022] The outer ring 201 has a slot 3 formed on its inner lower surface, and a clamping block 4 is fixedly connected to the lower surface of the connecting frame 202.

The inner ring 203 has a snap-fitting slot 5 formed on its upper portion, and a snap-fitting ring 6 is fixedly connected to the lower surface of the cover plate 206. The outer wall of the snap-fitting ring 6 is embedded in the inner wall of the snap-fitting slot 5.

[0023] By inserting the block 4 under the connecting frame 202 into the slot 3 in the outer ring 201, the connecting frame 202 can be fixed in the outer ring 201, and then the inner ring 203 rotates between the outer ring 201 and the connecting frame 202 to insert the snap ring 6 into the snap groove 5. Since the snap ring 6 and the cover plate 206 are an integral whole, the outer ring 201 and the cover plate 206 can form an integral whole.

[0024] The oil filling hole 207 is communicated with the oil storage tank 208 , the oil storage tank 208 is communicated with the oil passage 209 , the oil passage 209 is communicated with the oil guide groove 210 , and a sealing plug 218 is provided on the inner wall of the oil filling hole 207 .

[0025] The working principle and use process of this utility model:

[0026] When the device needs to be used, the bearing mechanism 2 will cause the roller to rotate during its rotation. When the roller rotates to the protrusion 211, it will squeeze the protrusion 211, thereby moving the wedge block 212 inward, so that the wedge block 212 is inserted into the wedge groove 215, and the slider 214 will move upward, so that the slider 214 and the piston 216 will be separated from the oil channel 209, and the oil in the oil storage tank 208 will flow from the oil channel 209 into the oil guide groove 210, so that the sponge ring 204 can absorb the lubricating oil and apply it to the ball 205, so that there is enough lubricating oil on the surface of the ball 205, and better lubrication can be performed when the bearing rotates, thereby ensuring that the shaft body 1 can overcome the situation where the shaft body 1 is easily damaged or broken under the condition of sufficient lubrication effect, and avoid the occurrence of steel piling problems caused by the breakage of the shaft body 1.
