Description

Sintering machine trolley wheels

technical field

The utility model relates to sintering machine equipment, in particular to a sintering machine trolley wheel.

Background technique

The sintering machine trolley is one of the important parts of the sintering machine, there are many of them, and the working environment is harsh. The trolley runs toward the tail after the head is filled with the mixed material (including the bottom material). The outer surface of the mixed material is ignited and sintered at the lower part of the ignition furnace. Under the action of the negative pressure of the draft, the mixed material is sintered and extends downward. After the sintering process is completed and unloaded at the tail of the sintering machine, the trolley returns along the lower track. The sintering machine trolley moves under the support of the wheels. In order to ensure the wheel bearings have a long service life, it is necessary to regularly add grease to the wheel bearings of the trolley. In the prior art, the oiling method of the trolley wheel bearing is that lubricating grease enters the bearing from the outside of the bearing, and under the action of oil pressure, the grease passes through the rolling bearing and is discharged from the other side of the bearing. The disadvantage of the prior art is: during the process of oiling the bearing of the trolley wheel of the sintering machine, the lubricating grease must enter the bearing from one side of the bearing, then pass through the rolling bearing, and be discharged from the other side of the bearing. Continuous movement, the resulting iron filings and other dirt will be mixed in the lubricating grease, when the lubricating grease passes through the rolling bearing, the iron filings and other dirt will stay inside the rolling bearing, the rolling bearing is easy to wear, and the service life is low. If it is not replaced in time, the axle of the trolley will also be damaged by the worn bearings, which makes the maintenance cost of the wheels of the sintering machine trolley very high; the wheels of the damaged sintering machine trolley are usually replaced as a whole, and the online damage The completed sintering machine trolley is disassembled as a whole, and the assembled spare sintering machine trolley is hoisted to the production line as a whole. It takes 2 hours for one hoisting, which has a negative impact on the production efficiency of the sintering machine trolley.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a sintering machine trolley wheel which can improve the service life of the bearing.

The trolley wheel of the sintering machine of the utility model includes a wheel body, a bearing and a trolley shaft. There is a grease channel, one end of the grease channel is provided with a grease nozzle, and the other end communicates with the lubricating port.

The first axle sleeve is sleeved on the axle of the trolley, and the second axle sleeve is installed at the end of the axle of the carriage. The bearing inner ring of the bearing is positioned through the first axle sleeve and the second axle sleeve, and the bearing outer ring of the bearing passes through the wheel body. It is positioned with the axle end cover installed on the wheel body.

The grease nozzle is installed on the second shaft sleeve and connected with the grease channel.

The axle end cover and the wheel body are respectively provided with seals.

Compared with the prior art, the utility model has the advantage that in the process of oiling the bearings of the wheels of the trolley of the sintering machine, the clean lubricating grease enters the grease passage set on the axle of the trolley from the grease nozzle, and then enters from the grease passage. The lubricating port is set on the inner ring of the bearing, and the lubricating grease is discharged from the inside of the bearing to the outside of the bearing under the action of pressure. The internal iron filings and other dirt are taken out of the bearing from the inside of the bearing, which can effectively prevent the damage of the iron filings and other dirt to the bearing and the damage of the worn bearing to the axle of the trolley, thus greatly improving the service life of the bearing and the axle of the trolley ;Reduce the replacement amount of the sintering machine trolley wheels, and reduce the maintenance cost of the sintering machine trolley; avoid interrupting the production progress of the sintering machine due to frequent replacement of the sintering machine trolley wheels, and improve the production efficiency of the sintering machine.

Detailed ways

As shown in Figure 1, the trolley wheel of the sintering machine of the present invention includes a wheel body 1, a bearing 2 and a trolley shaft 3, the bearing 2 is sleeved on the end of the trolley shaft 3, and the wheel body 1 is sleeved on the bearing 2, It is characterized in that the bearing inner ring 21 of the bearing 2 is provided with a lubricating port 211 , the trolley shaft 3 is provided with a grease channel 31 , one end of the grease channel 31 is provided with a grease nozzle 4 , and the other end communicates with the lubricating port 211 . The first shaft sleeve 32 is sleeved on the trolley shaft 3, and the second shaft sleeve 33 is installed at the end of the trolley shaft 3. The bearing inner ring 21 of the bearing 2 is positioned by the first shaft sleeve 32 and the second shaft sleeve 33, and the bearing The bearing outer ring 22 of 2 is positioned by the wheel body 1 and the axle end cover 5 installed on the wheel body 1. The grease nozzle 4 is mounted on the second bushing 33 and connected to the grease channel 31 . Sealing elements 6 are respectively provided on the axle end cover 5 and the wheel body 1 . A first oil chamber 7 is formed between the first shaft sleeve 32 , the bearing 2 and the wheel body 1 , and a second oil chamber 8 is formed between the second shaft sleeve 33 , the bearing 2 and the shaft end cover 5 . When the sintering machine is working, the sintering machine trolley is pushed forward by the power device, the wheel body 1 rotates, and the trolley axle 3 does not rotate. When adding lubricating grease to the bearing 2, the clean lubricating grease enters from the grease nozzle 4, and enters the inside of the bearing 2 through the grease channel 31 on the carriage shaft 3 and the lubricating port 211 on the bearing inner ring 21, and the original part in the bearing 2 is redundant. Grease is squeezed into the first oil chamber 7 and the second oil chamber 8 , and excess grease in the first oil chamber 7 and the second oil chamber 8 is discharged through the seal 6 . Therefore, when adding grease, the excess grease in the first oil chamber 7 and the second oil chamber 8 does not enter the bearing 2, which ensures that the bearing 2 works in a clean environment. During this process, the lubricating grease not only did not bring the iron filings and other dirt outside the bearing 2 into the bearing 2, but also brought the iron filings and other dirt that entered the inside of the bearing 2 out of the bearing 2, thus greatly Improve the service life of the bearing 2. The trolley works continuously for 24 hours. When filling the lubricating grease, it needs to be carried out during the movement of the trolley. Since the trolley shaft 3 does not rotate, this structure maintains the feature of convenient refueling.
