Description

Technical Field

[0001] This utility model patent belongs to the technical field of paper mill bearing lubrication equipment, specifically relating to a vacuum idler roller bearing lubrication device. Background Technology

[0002] Bearing housings are among the most commonly used mechanical parts in the field of mechanical transmission. They are present in almost every application where bearings are used. A bearing housing is a component mounted on the machine body or foundation to support the bearing. It serves to install and fix the bearing, and can withstand a certain amount of support force. The bearing, mounted on the housing, rotates synchronously with the shaft through its mating mechanism. Bearing housings are widely used in various fields such as forging, smelting, heat treatment, boilers, dust collectors, and material conveying.

[0003] This technology has also found applications in the paper manufacturing industry, such as in the vacuum idler roller bearing housing of vacuum cylinder paper machines used for producing household paper. However, through actual production research, the inventors discovered that the original sealing device on the vacuum idler roller bearing housing does not meet the requirements of actual operating conditions. Firstly, water ingress into the bearing chamber is severe, leading to poor lubrication. Secondly, the bearing is lubricated with grease, requiring replenishment of grease twice a week, which is inefficient, labor-intensive, and costly to maintain.

[0004] To address the aforementioned problems, this utility model proposes a vacuum idler roller bearing lubrication device. Utility Model Content

[0006] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: a vacuum idler roller bearing lubrication device, including a waterproof bearing seat, a circulating oiling mechanism, and a control device. The plurality of waterproof bearing seats can be connected to the circulating oiling mechanism, which can cool, pump, and filter the lubricating oil, via pipelines. The circulating oiling mechanism further includes a cooling mechanism, an oil storage tank, an oil pump, and a lubricating oil filter. The cooling mechanism is installed on the top of the oil storage tank and connects the return end of the pipeline and the inlet end of the oil storage tank via its internal heat exchange coil. The left outlet end of the oil storage tank is connected to the pipeline, and an oil pump and a lubricating oil filter are sequentially arranged on it. The control device is electrically connected to the electrical control components in the cooling mechanism, oil storage tank, oil pump, and lubricating oil filter.

[0007] Preferably, the pipeline further includes a main oil supply pipe, secondary oil supply pipes, a main oil return pipe, and secondary oil return pipes. The main oil supply pipe connects the left oil outlet of the oil storage tank to the front ends of several secondary oil supply pipes. An oil pump and a lubricating oil filter are sequentially installed on the main oil supply pipe to the left of the left oil outlet of the oil storage tank. The end of the secondary oil supply pipe is connected to the oil inlet of the waterproof bearing housing, and a solenoid valve A and a flow meter are installed on the end of the secondary oil supply pipe. The main oil return pipe connects the heat exchange coil to the ends of several secondary oil return pipes. The front end of the secondary oil return pipe is connected to the oil outlet of the waterproof bearing housing, and a solenoid valve A and a flow meter are installed on the front end of the secondary oil return pipe. A one-way valve is installed on the main oil return pipe to the right of the end of each secondary oil supply pipe to restrict the liquid flow to the heat exchange coil.

[0008] Preferably, the cooling mechanism further includes a cooling chamber, a liquid level sensor A, and a temperature sensor. The top of the cooling chamber is provided with a water inlet and a refueling end that connects to the oil storage tank. The rear side of the cooling chamber is provided with a water outlet. The cooling chamber is equipped with a liquid level sensor A and a temperature sensor (not shown in the figure).

[0009] Preferably, the water inlet is connected to a water pump in an open-air cooling water tank (connection not shown in the diagram) via an inlet pipe; this design allows users to precisely control the water level and temperature in the cooling chamber by controlling the rate of water entering and leaving the chamber.

[0010] Preferably, a solenoid valve B (not shown in the figure) is provided on the water outlet end; this design allows the user to easily control the efficiency of the cooling chamber's drainage.

[0011] Preferably, a liquid level sensor B (not shown in the figure) is installed in the oil storage tank, and an oil drain end is provided at the bottom of the oil storage tank; this structure is designed to facilitate the detection of the liquid level in the tank when refueling.

[0013] Preferably, a temperature sensor is provided on the waterproof bearing housing; this structure can be installed on the waterproof bearing housing of the vacuum idler roller used at high frequencies.

[0014] The beneficial effects of this utility model are: 1. The waterproof bearing housing design avoids water ingress during lubrication, preventing poor lubrication. The main pipe, auxiliary pipe, solenoid valve, and flow meter design allow for appropriate oil injection for each bearing housing under different usage scenarios. This avoids the situation where excessive or insufficient grease injection causes high temperature of the idler roller, leading to increased grease consumption and unreliable lubrication, resulting in dry friction. 2. With the addition of a circulating lubrication mechanism, lubrication of the bearings can be achieved without the operator having to climb to the lower idler roller during the grease application process. This reduces safety hazards caused by improper operation, thereby improving work efficiency, reducing operational difficulty, reducing the occurrence of poor lubrication of the idler roller bearings, and extending bearing life. At the same time, it can cool down the high-temperature lubricating oil under high-frequency operation and filter the circulating lubricating oil, thus saving maintenance costs.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0017] The existing technology in this embodiment has the following problems: Through actual production research, the inventors discovered that the original factory sealing device on the vacuum roller bearing housing does not meet the requirements of actual operating conditions, such as... Figure 1 Firstly, the bearing housing was severely flooded, leading to poor lubrication. Secondly, the bearing was lubricated manually with grease, requiring replenishment twice a week, which was inefficient, labor-intensive, and costly.

[0018] Therefore, as Figures 2 to 7 As shown, the inventor provides a vacuum roller bearing lubrication device, including a waterproof bearing housing 1 (detailed structure as shown in the figure). Figure 2 The system includes a circulating oil filling mechanism and a control device (not shown in the figure). Several waterproof bearing seats 1 can be connected to the circulating oil filling mechanism, which cools, pumps, and filters the lubricating oil, via pipes. The circulating oil filling mechanism also includes a cooling mechanism, an oil storage tank 2, an oil pump 3, and a lubricating oil filter 4. The cooling mechanism is installed on top of the oil storage tank 2 and connects the return end of the pipe and the inlet end of the oil storage tank 2 via its internal heat exchange coil 18. The left outlet end 9 of the oil storage tank 2 is connected to the pipe, and the oil pump 3 and the lubricating oil filter 4 are sequentially installed on it. The control device is electrically connected to the electrical control components in the cooling mechanism, oil storage tank 2, oil pump 3, and lubricating oil filter 4.

[0019] Furthermore, it also includes a main oil supply pipe 5, a secondary oil supply pipe 6, a main oil return pipe 7, and a secondary oil return pipe 8. The main oil supply pipe 5 connects to the left oil outlet 9 of the oil storage tank 2 and the front ends of several secondary oil supply pipes 6. An oil pump 3 and a lubricating oil filter 4 are sequentially installed on the main oil supply pipe 5 to the left of the left oil outlet 9 of the oil storage tank 2. The end of the secondary oil supply pipe 6 is connected to the oil inlet of the waterproof bearing seat 1, and a solenoid valve A10 and a flow meter 11 are installed on the end of the secondary oil supply pipe 6. The main oil return pipe 7 connects to the heat exchange coil 18 and the ends of several secondary oil return pipes 8. The front end of the secondary oil return pipe 8 is connected to the oil outlet of the waterproof bearing seat 1, and a solenoid valve A10 and a flow meter 11 are installed on the front end of the secondary oil return pipe 8. A one-way valve 12 is installed on the right side of the end of each secondary oil pipe on the main oil return pipe 7 to restrict the liquid to flow only towards the heat exchange coil 18. By adopting the above technical solution, the main oil supply pipe 5 and the main oil return pipe 7 can be set below multiple sets of vacuum idlers. The waterproof bearing housing 1 is connected to the main oil supply pipe 5 and the main oil return pipe 7 respectively by using a corresponding number of auxiliary oil supply pipes 6 and auxiliary oil return pipes 8. This allows for the lubrication of the vacuum idlers in the factory, saving labor costs and improving work efficiency. At the same time, the temperature of the waterproof bearing housing 1 of the vacuum idlers under different usage scenarios can be detected. In conjunction with the circulating lubrication mechanism and the solenoid valve A10 and flow meter 11 on the auxiliary oil supply pipes 6 and 8, the control device can easily control the replacement efficiency and heat exchange efficiency of the lubricating oil in the waterproof bearing housing 1 of the vacuum idlers under different usage scenarios.

[0020] Furthermore, the cooling mechanism also includes a cooling chamber 13, a liquid level sensor A, and a temperature sensor. The top of the cooling chamber 13 is provided with a water inlet 14 and a refueling end 15 that connects to the oil storage tank 2. The rear side of the cooling chamber 13 is provided with a water outlet 16. The cooling chamber 13 is provided with a liquid level sensor A and a temperature sensor (not shown in the figure). By adopting the above technical solution, when adding water to the cooling chamber 13, the water level can be detected by the liquid level sensor A to ensure that the water level can cover the heat exchange coil 18. When the temperature sensor detects that the water temperature in the chamber exceeds the alarm value, the water in the chamber can be replaced through the inlet 14 and the outlet 16. It can be seen that the design of the inlet 14 and the outlet 16 in the cooling chamber 13 mechanism is to facilitate the user to change the heat exchange medium in the cooling chamber 13, thereby improving the heat exchange efficiency. The design of the top oil filling end 15 of the cooling chamber 13 is to facilitate the filling of oil from above the oil storage tank 2. The design of the liquid level sensor A and the temperature sensor is to facilitate the detection of the water level and water temperature in the cooling chamber 13, thereby facilitating the control of the water level and water temperature.

[0021] Furthermore, the water inlet 14 is connected to a water pump in the open-air cooling water tank (connection not shown in the diagram) via an inlet pipe; this structure is designed to allow users to precisely control the water level and temperature in the cooling chamber 13 by controlling the rate of water entering and leaving the chamber.

[0022] Furthermore, a solenoid valve B (not shown in the figure) is installed on the water outlet 16; this structure is designed to facilitate user control of the drainage efficiency of the cooling chamber 13.

[0023] Furthermore, a liquid level sensor B (not shown in the figure) is installed in the oil storage tank 2, and an oil drain end 17 is provided at the bottom of the oil storage tank 2; this structure is designed to facilitate the detection of the liquid level in the tank when refueling. Similarly, a solenoid valve can also be installed on the oil drain end 17.

[0024] Furthermore, the control device also includes a control cabinet, a processor, a display, control buttons, and a power supply. The control cabinet is equipped with the processor, display, control buttons, and power supply. The processor is electrically connected to the electronic control components in the display, control buttons, power supply, cooling mechanism, oil reservoir 2, oil pump 3, and lubricating oil filter 4. The power supply provides power to the processor, display, control buttons, cooling mechanism, oil reservoir 2, oil pump 3, and lubricating oil filter 4.

[0025] Furthermore, a temperature sensor (not shown in the figure) is provided on the waterproof bearing housing 1; this structure can be installed on the waterproof bearing housing 1 of the vacuum idler roller used at high frequencies.

[0026] The working principle of this utility model: Before starting the wet end creep (with vacuum idler roll) when starting the Yankee cylinder of the paper machine, check the cooling mechanism and oil storage tank 2 in the circulating oiling system via the control device to ensure that heat exchange medium (water) and lubricating oil have been added. Then, open the valves connecting the oil supply and return lines of the vacuum idler roll via the control device, start the lubricating oil pump 3, ensure that the lubricating oil supply and return are normal, and ensure that the air in the pipeline and waterproof bearing housing 1 is purged before starting the wet end creep. Otherwise, do not start the wet end to avoid burning out the bearings of the vacuum idler roll due to lack of oil lubrication. During the process, the liquid level and water temperature can be monitored in real time by the liquid level sensor and temperature sensor in the cooling chamber 13 and the oil storage chamber 2. In order to facilitate the control device to control the replacement efficiency and heat exchange efficiency of the lubricating oil in the waterproof bearing seat 1 of the vacuum idler under different usage scenarios, a temperature sensor can also be installed on the waterproof bearing seat 1. When the paper machine stops, by gradually reducing the speed of the Yanke cylinder to below 30m / min, the vacuum idler is disengaged, the wet end is stopped, and after the machine stops completely, the lubricating oil pump 3 is finally stopped, and the oil supply and return pipeline valves are closed.
