[0002] In industrial production, belt conveyors are crucial material conveying equipment, and the normal operation of their roller bearing housings plays a key role in the stability and reliability of the entire conveying system. During long-term operation, roller bearing housings generate a large amount of heat due to friction. If lubrication and heat dissipation are inadequate, it will not only accelerate bearing wear and shorten bearing life, but may also lead to belt conveyor malfunctions and downtime, affecting production efficiency and increasing maintenance costs. Currently, most existing belt conveyor roller bearing housing lubrication devices rely on simple, periodic manual oiling. This method suffers from untimely and uneven lubrication, failing to meet the demands of high-speed, long-term operation. Especially for high-level oil supply, it is not only cumbersome but also poses certain safety hazards. While some automated lubrication devices can achieve automatic oil supply, they lack effective heat dissipation structures. Operating the bearing housing in a high-temperature environment, the lubricating oil's performance is prone to deterioration, further affecting lubrication effectiveness. Therefore, developing a belt conveyor roller bearing housing lubrication device that can achieve automatic lubrication and possess efficient heat dissipation capabilities is of significant practical importance.

Detailed Implementation

[0017] Example 1: like Figure 1-4 In the present invention, a lubrication device for a belt conveyor roller bearing housing includes an oil supply device 1, wherein the oil supply device 1 is connected to a bearing housing structure 3 via an oil supply pipe 2, and the bearing housing structure 3 is connected to a cooling water tank 6 via a water circulation pipe. The oil supply device 1 includes a housing 8, on which a door 9 is installed via a hinge structure. Inside the housing 8, there is an oil storage tank 10 and an electrical control box 15. An electric oil pump 11 is installed at the bottom of the oil storage tank 10. The electric oil pump 11 is connected to an oil distribution pipe 14 via an oil outlet pipe 12. A reversing valve 13 is installed on the oil distribution pipe 14, which is connected to the oil supply pipe 2.

[0018] In a preferred embodiment, a safety valve 16 is provided on the oil outlet pipe 12.

[0019] In a preferred embodiment, the oil outlet pipe 12 is equipped with a pressure controller 17.

[0020] In a preferred embodiment, the water circulation pipeline includes a water supply pipeline 4 and a water return pipeline 5, and an electric water pump 7 is installed on the water supply pipeline 4.

[0021] In a preferred embodiment, the bearing housing structure 3 includes a housing 18, a fixing bolt 19 for installation on the housing 18, a lubrication cavity 20 inside the housing 18, a plurality of oil through holes 22 that cooperate with the bearing installation position inside the lubrication cavity 20, and an oil supply connector 21 that communicates with the lubrication cavity 20 on the housing 18, and the oil supply connector 21 is connected to the oil supply pipe 2. In a preferred embodiment, the seat 18 is provided with a cooling chamber 23, which is connected to a water supply connector 24 and a water return connector 25 provided on the seat 18. The water supply connector 24 and the water return connector are connected to a water circulation pipeline.

[0022] In a preferred embodiment, the lubrication cavity 20 inside the seat 18 is located in the upper half of the seat 18, and the cooling cavity 23 is located in the lower half of the seat 18.

[0023] In a preferred embodiment, both ends of the oil supply pipe 2 are provided with compression fittings 26.

[0024] In the preferred embodiment, the oil supply pipe 2 is made of galvanized seamless steel pipe.

[0025] Example 2: like Figure 1-4 In this device, the main components are an oil supply device 1, a bearing housing structure 3, and a cooling water tank 6. The oil supply device housing 8 is welded from Q235-A steel plate and coated with an epoxy resin anti-corrosion layer. The housing door 9 is connected to the housing by stainless steel hinges, and the sealing strip ensures an IP54 protection rating. The bearing housing 18 is cast from ductile iron QT400-18. The internal lubrication chamber 20 and cooling chamber 23 are formed by core casting. A 5mm thick heat insulation layer is provided between the two chambers to reduce heat conduction interference. The oil supply pipe 2 is made of galvanized Q235 low carbon steel. One end 26 of the oil supply pipe 2 uses a 304 stainless steel M10*1.5-φ10 compression fitting adapter 26 to replace the original lubrication nozzle of the roller bearing housing. The other end of the oil supply pipe 2 uses a 304 stainless steel φ10-M10*1.5 compression fitting adapter to connect to the oil supply device 1.

[0026] Example 3: like Figure 1-4 The working principle of this utility model is as follows: When the belt conveyor starts running, the electrical control box 27 controls the electric oil pump 11 to start working. The lubricating oil in the oil storage tank 10 is transported to the oil distribution pipe 14 through the oil outlet pipe 12 under the action of the electric oil pump 11. The reversing valve 13 on the oil distribution pipe 14 can adjust the flow direction of the lubricating oil according to actual needs, ensuring that the lubricating oil can be accurately delivered to each part that needs lubrication. The lubricating oil enters the oil supply pipe 2 through the oil distribution pipe 14, and then enters the lubrication chamber 20 through the oil supply connector 21 of the bearing housing structure 3. Finally, it reaches the bearing installation position through the oil permeation hole 22 in the lubrication chamber 20 to lubricate the bearing. At the same time, the safety valve 16 on the oil outlet pipe 12 monitors the system pressure in real time. When the pressure exceeds the set value, the safety valve 16 automatically opens to relieve pressure and ensure system safety. The pressure controller 17 precisely controls the oil supply pressure to ensure that the lubricating oil is supplied at a stable and appropriate pressure. The electric water pump 7 starts to operate under the control of the electrical control box 27. The cooling water in the cooling water tank 6 enters the cooling chamber 23 of the bearing housing structure 3 through the water supply pipe 4. During the flow of the cooling water in the cooling chamber 23, it absorbs the heat generated by the operation of the bearing housing and the temperature rises. The heated cooling water flows back to the cooling water tank 6 through the return water connector 25 and the return water pipe 5. In the cooling water tank 6, it is cooled down by heat dissipation devices such as heat sinks and fans or by natural cooling, and then participates in the circulation again, thereby realizing the continuous cooling of the bearing housing and ensuring that the bearing housing operates stably at a lower temperature.

[0027] The beneficial effects of this utility model are as follows: It can automatically supply oil to the bearing housing structure, which, compared with the traditional manual oiling method, can ensure the timeliness and uniformity of lubrication, effectively prevent excessive system pressure, ensure the safe operation of the device, and achieve precise control of the oil supply pressure; it can effectively reduce the temperature of the bearing housing, avoid the deterioration of lubricating oil performance due to high temperature, ensure that the bearing works in a suitable temperature environment, and extend the service life of the bearing and lubricating oil; the reasonable layout of the lubrication chamber and cooling chamber, as well as the cooperation and connection between various components, make the entire device compact in structure, convenient in installation and maintenance, and can be widely used in various belt conveyor equipment.
