Description

Technical Field

[0001] The utility model belongs to the technical field of grinding machines, in particular to a bearing seat system for grinding machines. Background Art

[0002] The rubber grinder grinds rubber particles into powder and is one of the key equipment in rubber production. The speed of the rubber grinder is high, and the bearing will heat up during the grinding process. In order to ensure the long-term stable operation of the bearing, the bearing needs to be cooled in time. At present, the bearing generally adopts air cooling, water cooling and oil cooling to dissipate heat. Among them, water cooling and oil cooling can be achieved by relying on the simple structure of the bearing sleeve, so the method of connecting the bearing sleeve to the circulating refrigerant to cool the bearing has been widely used.

[0003] As far as the prior art is concerned, the existing bearing water-cooling or oil-cooling structure is mostly a cylindrical cooling cavity, in which the refrigerant circulates. Due to the pipeline resistance when the refrigerant flows in the cylindrical cavity, the cooling effect is good at the water inlet, while the cooling effect at the water outlet becomes poor due to the increase in refrigerant temperature and the decrease in flow rate.

[0004] In addition, most existing cooling cavities are closed cavities with only refrigerant inlets and outlets. The inside of the cooling cavity cannot be cleaned, and impurities accumulate and adhere to the cavity, which will lead to a reduction in the flow channel and dead corners in the cooling area, resulting in local overheating, thereby causing the bearing sleeve to have a poor heat dissipation effect on the bearing.

[0005] In addition, the cooling effect of existing bearing sleeves is generally judged by the change in refrigerant temperature. This indirect judgment method is not accurate, resulting in a mismatch between the refrigerant circulation speed and the cooling effect required by the bearing.

[0006] In summary, the existing bearing sleeve cooling bearing solution has the problems of poor circulation flow, difficult cleaning and mismatch between cooling supply and demand. Utility Model Content

[0007] The purpose of the utility model is to provide a bearing seat system for a grinding machine to solve the above-mentioned problems existing in the prior art.

[0008] Technical solution: A bearing seat system for a grinding machine includes a bearing seat, a plurality of bearings arranged in an axial hole of the bearing seat, and bearing end covers installed at both ends of the bearing seat. The bearing seat is provided with a sensor module for monitoring the operating status of the bearing.

[0009] Furthermore, the sensor module includes a vibration sensor for monitoring bearing vibration, the bearing seat has a body of a rotating body, a vibration measuring hole is provided on an outer wall of the body, and the vibration sensor is arranged in the vibration measuring hole.

[0010] Furthermore, the sensor module includes a temperature sensor for monitoring the bearing temperature. The seat body of the bearing seat is a rotating body structure. The outer wall of the seat body is provided with a temperature measuring hole. The temperature measuring hole is connected to the shaft hole, and the temperature sensor is arranged in the temperature measuring hole.

[0011] Furthermore, the seat body is a casting, the casting hole of the seat body is sealed by a sealing plate, the seat body casting cavity and the sealing plate form a cooling cavity, the cooling cavity is a conical cavity structure, and the seat body is provided with a circulation interface that penetrates the cooling cavity.

[0012] Furthermore, the sensor module includes a rotation speed sensor, which is installed on the bearing end cover and is used to monitor the rotation speed of the transmission shaft, and the transmission shaft is arranged in the bearing.

[0013] Furthermore, a lubricating oil chamber is formed between the transmission shaft, the bearing and the shaft hole, and the lubricating oil chamber is connected to the lubricating oil pump through a lubricating interface extending to the outside of the seat body.

[0014] Furthermore, the sensor module also includes an industrial control module, and the industrial control module is electrically connected to the output end of the sensor.

[0015] Beneficial effect: The utility model uses a sensor module to detect the working status of the bearing, and can accurately obtain the cooling amount required by the bearing. Compared with the traditional method of judging the refrigerant temperature change to reflect the bearing cooling demand, it is more direct and accurate, and improves the matching degree between the refrigerant circulation speed and the cooling effect required by the bearing.

[0016] In addition, the cooling cavity with a conical cavity structure has flow enhancement characteristics, which can cause the fluid in the cavity to circulate and at the same time discharge the gas in the refrigerant from the cavity. The heat exchange effect is better than that of a cylindrical cavity.

[0017] In addition, the cooperation between the seat body and the sealing plate can not only realize the formation of the cooling cavity, but also meet the requirements of cleaning the seat body after removing the sealing plate, thereby avoiding the accumulation of impurities in the cooling cavity.

[0018] In summary, the bearing seat system provided by the utility model solves the problems of poor circulation flow, difficult cleaning and mismatch between cooling supply and demand in traditional bearing sleeve cooling bearings, and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] like Figure 1-Figure 3 As shown, a bearing seat system for a grinding machine includes a bearing seat 1, a plurality of bearings arranged in an axial hole 13 of the bearing seat 1, and bearing end covers 2 installed at both ends of the bearing seat 1. The bearing seat 1 is provided with a sensor module for monitoring the operating status of the bearing.

[0025] The utility model uses a sensor module to detect the working status of the bearing, and can accurately obtain the cooling amount required by the bearing. Compared with the traditional method of judging the refrigerant temperature change to reflect the bearing cooling demand, it is more direct and accurate, and improves the matching degree between the refrigerant circulation speed and the cooling effect required by the bearing. Installing the sensor module on the bearing seat 1 has little improvement on the structure of the bearing seat 1, has low integration difficulty, and is easy to realize the transformation of traditional equipment.

[0026] The sensor module includes a vibration sensor for monitoring the vibration of the bearing. The seat body 11 of the bearing seat 1 is a rotating body structure. The outer wall of the seat body 11 is provided with a vibration measuring hole. The vibration sensor is arranged in the vibration measuring hole. The installation position and number of the vibration sensor match the bearing. Therefore, there are at least two vibration sensors, such as Figure 1 and Figure 3 As shown, when the number of bearings is at least two, two vibration sensors are installed on the front vibration measuring hole 18 and the bearing end cover 2 respectively. The front bearing vibration sensor 4 is installed on the front vibration measuring hole 18, and the rear bearing vibration sensor 5 is installed on the bearing end cover 2. The two vibration sensors perform vibration detection on both ends of the bearing seat 1, and can promptly respond to abnormalities of the bearing seat 1, thereby playing a role in timely response in abnormal shutdown of the equipment.

[0027] The sensor module includes a temperature sensor for monitoring the bearing temperature. The seat body 11 of the bearing seat 1 is a rotating body structure. The outer wall of the seat body 11 is provided with a temperature measuring hole, which is connected to the shaft hole 13. The temperature sensor is arranged in the temperature measuring hole. The installation position and number of the temperature sensor match the bearing, so there are at least two vibration sensors, such as Figure 1 and Figure 3 As shown, when the number of bearings is at least two, the front bearing temperature sensor 7 is installed in the front temperature measuring hole 16, and the rear bearing temperature sensor 8 is installed in the rear temperature measuring hole 17. The two temperature sensors are in direct contact with the bearings to obtain the most accurate bearing temperature. The refrigerant circulation efficiency can be adjusted according to the actual measured temperature of the bearings to achieve the purpose of precise temperature control of the bearings. In addition, by comparing the temperatures of the two bearings, the uniformity of the refrigerant circulation and the uniformity of the cooling effect in the bearing seat can be judged.

[0028] The seat body 11 is a casting, and the casting hole 19 of the seat body 11 is sealed by a sealing plate 12. The casting cavity of the seat body 11 and the sealing plate 12 form a cooling cavity 14. The cooling cavity 14 is a conical cavity structure. The seat body 11 is provided with a circulation interface 15 that penetrates the cooling cavity 14. The cooling cavity 14 can be sealed by blocking the casting hole 19 with the sealing plate 12. After removing the sealing plate 12, the seat body 11 can be cleaned to avoid the accumulation of impurities in the cooling cavity 14. The cooling cavity 14 with a conical cavity structure has a flow enhancement characteristic, which can circulate the refrigerant in the cavity and discharge the gas in the refrigerant from the cavity. The heat exchange effect is better than that of a cylindrical cavity.

[0029] The sensor module includes a speed sensor 6, which is mounted on the bearing end cover 2 and is used to monitor the speed of the transmission shaft 3. The transmission shaft 3 is arranged in the bearing. The installation position of the speed sensor 6 is provided by the transmission shaft 3. The speed sensor 6 can detect the running state of the transmission shaft 3. The speed sensor 6 cooperates with the driving end that drives the transmission shaft 3 to rotate, and can determine whether the efficiency of power transmission meets the standard.

[0030] A lubricating oil chamber is formed between the transmission shaft 3, the bearing and the shaft hole 13, and the lubricating oil chamber is connected to the lubricating oil pump through a lubricating interface extending to the outside of the seat body 11. The existence of the lubricating oil chamber can replace the solid grease required by the original bearing with liquid lubricating oil. When adding liquid lubricating oil, it is only necessary to add a sufficient amount of lubricating oil to the bearing group on one side. The rotating shaft transfers the lubricating oil to the other bearing group when driving the oil guide ring to rotate, making it convenient and quick to add lubricating oil.

[0031] The sensor module also includes an industrial control module, which is electrically connected to the output end of the sensor (temperature sensor, vibration sensor and speed sensor). The industrial control module is the output end of the grinder, which is electrically connected to the major functional units of the grinder, and promptly feeds back the information monitored by the sensor module to maintain efficient and stable operation of the equipment.

[0032] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
