Abstract
Description
Technical Field
[0001] The utility model relates to the field of pressing rollers, and particularly relates to a bearing chamber for a pressing roller. Background Art
[0002] The pressing roller is the main component of the pressing device of a paper machine. Among them, the bearing chamber is a component used to support the rotating pressing roller. During the operation of the shaft in the bearing chamber, the grease needs to be guided along the oil injection hole and the oil passage to the friction surface to form a lubricating film, so as to reduce the heat and wear generated by the bearing due to friction;
[0003] In the existing oil passage, it is usually an annular groove opened on the inner wall of the bearing chamber. This method usually cannot spread quickly to the entire friction surface during the oil injection process, and the oil injection speed is slow and the oil injection volume cannot be increased, which will directly reduce the production efficiency. At the same time, this connection cannot ensure that the grease evenly covers the entire friction surface, so effective lubrication cannot be obtained, resulting in a shortened service life of the bearing;
[0004] At the same time, the bearing chamber also needs to be regularly replenished with grease. The existing method of replenishing grease usually uses manual labor to pull the grease machine to the vicinity of the bearing chamber that needs to be replenished with grease, install the pipeline on the oil injection port of the bearing chamber, and then replenish the grease. Since the replenishment of grease is a regular behavior, this will directly increase the labor intensity of the operator, and at the same time, the operation is cumbersome, the efficiency is low, and the production efficiency cannot be improved. Summary of the Utility Model
[0005] In order to solve the above existing problems, the utility model provides a bearing chamber for a pressing roller.
[0006] The utility model is realized through the following technical solutions:
[0007] A bearing chamber for a pressing roller, comprising a frame. At both ends of the upper part of the frame, there are bearing chambers for rotatably supporting the pressing roller. An oil injection port is arranged on the outside of the bearing chamber. A main oil passage is annularly arranged in the bearing chamber. The left and right sides of the main oil passage are respectively communicated with a first sub-oil passage and a second sub-oil passage. The corresponding first sub-oil passage and the second sub-oil passage are respectively composed of a plurality of arc-shaped grooves connected end to end. The connection part of the corresponding arc-shaped grooves is communicated with the main oil passage. An oil injection assembly is connected to the oil injection port.
[0008] Further optionally, the oil injection port is communicated with the main oil passage.

An end cover is arranged at the upper part of the grease storage tank. An electric push rod is arranged at the upper part of the end cover. The telescopic rod of the electric push rod penetrates through the end cover and extends into the grease storage tank and is connected with a pressing plate at the end.

[0011] Further optionally, a sealing ring is provided between the pressing plate and the grease storage tank.
[0012] Further optionally, the oil injection assembly is fixed to the outside of the bearing chamber through a bracket.
[0013] Compared with the existing technology, the beneficial effects of the present utility model are as follows: By adding two auxiliary oil channels on both sides of the oil channel, the present utility model fundamentally solves a series of problems caused by filling grease, better increases the oil inlet volume, and at the same time ensures that the grease can evenly cover the entire friction surface, better extending the service life of the bearing; moreover, an oil injection assembly is installed at the oil injection port, which better reduces the labor intensity of the operator, speeds up the work efficiency, and greatly improves the production efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments:
[0020] As Figure 1 , 3 shown, a bearing chamber for a pressing roller includes a frame 1, and bearing chambers 3 for rotatably supporting the pressing roller 2 are provided at both ends of the upper part of the frame 1. An oil injection port 7 is provided outside the bearing chamber 3. It is characterized in that: a main oil channel 8 is annularly arranged in the bearing chamber 3, and a first auxiliary oil channel 9 and a second auxiliary oil channel 10 are respectively communicated with the left and right sides of the main oil channel 8. The corresponding first auxiliary oil channel 9 and second auxiliary oil channel 10 are respectively composed of a plurality of arc-shaped grooves connected end to end. The connection points of the corresponding arc-shaped grooves are communicated with the main oil channel 8, and an oil injection assembly is connected to the oil injection port 7.
[0021] As Figure 3 shown, the oil injection port 7 is communicated with the main oil channel 8.
[0022] As shown Figure 1 , 2 , as shown in Fig. 4, the grease injection assembly includes a grease storage tank 5. An oil outlet 11 is provided at the lower part of the grease storage tank 5, and an end cover 51 is provided at the upper part of the grease storage tank 5. An electric push rod 6 is provided at the upper part of the end cover 51. The telescopic rod of the electric push rod 6 penetrates through the end cover 51 and extends into the interior of the grease storage tank 5 and is connected with a pressing plate 12 at the end.
[0023] As shown Figure 4 , the lower inner side of the grease storage tank 5 is conical.
[0024] As shown Figure 4 , a sealing ring is provided between the pressing plate 12 and the grease storage tank 5.
[0025] As shown Figure 1 , 2 , the grease injection assembly is fixed to the outside of the bearing chamber 3 through a bracket 4.
[0026] The implementation principle of the bearing chamber for a pressing roller in the embodiment of the present application is as follows:
[0027] Before injecting oil into the bearing chamber 3, first inject the lubricating grease into the grease storage tank 5. After injection, prepare for oil injection;
[0028] When injecting oil, start the electric push rod 6. After the electric push rod 6 starts, the telescopic rod extends out. The extension of the telescopic rod will cause the pressing plate 12 to press down. The pressing down of the pressing plate 12 will squeeze the lubricating grease out of the oil outlet 11 and enter the bearing chamber 3 from the oil injection port 7. The lubricating grease entering the bearing chamber 3 will flow along the main oil passage 8. At the same time, the lubricating grease entering the main oil passage 8 will be divided into the corresponding first sub-oil passage 9 and the second sub-oil passage 10. Due to the enlarged oil filling area, the oil intake will be directly increased, the production efficiency will be improved. At the same time, after the oil filling area is enlarged, the lubricating grease entering the main oil passage 8, the first sub-oil passage 9 and the second sub-oil passage 10 will be more evenly distributed on the friction surface of the bearing, so that the friction surface can be lubricated sufficiently and effectively;
[0029] After the lubricating grease is filled, stop the movement of the electric push rod 6, thus completing the work of injecting the lubricating grease. The whole process saves time and effort, relieves the labor intensity of the operating workers, and at the same time speeds up the oil injection efficiency and improves the production efficiency.
