Description

Technical Field

[0001] The utility model relates to a bearing bracket, in particular to a water-cooled bearing seat. Background Art

[0002] In industrial production, bearings are usually installed in processing equipment. In order to improve the installation stability of the bearings, bearing seats are usually configured at the bearing installation positions, such as the application of bearing seats in grinding equipment. Currently, the bearing seats on the market are mainly made by welding carbon steel plates and resin sand casting. With the continuous increase in production capacity and demand at the user end, the demand for grinding equipment is also increasing. The bearing seats in grinding equipment are correspondingly made larger and larger. When the bearings are working, they will generate high temperatures. Especially for larger bearing seats, the temperatures generated during their operation are also higher. It is necessary to cool the bearing seats in time to reduce high maintenance costs. Therefore, there is an urgent need for a bearing seat with better cooling and temperature reduction effects. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a water-cooled bearing seat to solve one or more technical problems in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] A water-cooled bearing seat includes: a base, in which two vertical plates are arranged at intervals in the left-right direction, and openings facing each other are respectively arranged on the two vertical plates; an outer cylinder, which is located between the two vertical plates, and a water inlet and a water outlet are arranged on the outer cylinder; an inner cylinder, which passes through the outer cylinder, and both ends of the inner cylinder are respectively located in the two openings, and support ribs are connected between the inner cylinder and the outer cylinder; a rotating shaft, which passes through the inner cylinder, and a connecting bearing is connected between the rotating shaft and the inner cylinder.

[0006] This technical solution has at least the following beneficial effects: The two vertical plates arranged at intervals in the left-right direction in the base can form two structures for supporting the inner cylinder, fixing the inner cylinder. The outer cylinder is located between the two vertical plates, and the support ribs can provide support and positioning for the outer cylinder. The rotating shaft is fixed in the inner cylinder through the connecting bearing, and can rotate self-driven by an external driving source, and drive the external structural parts to rotate, such as a grinding rotor. An annular cooling cavity is formed by enclosing between the outer side of the inner cylinder, the inner side of the outer cylinder and the two vertical plates. When the rotating shaft is working, cold water can be injected into the cooling cavity from the water inlet, and the heat conducted from the connecting bearing to the inner cylinder is taken away by the cold water, and then the cooling water is output from the water outlet. In this way, through water cooling and temperature reduction, the rotating shaft and the connecting rotating shaft can be cooled and temperature-reduced in time, so that the whole bearing seat can maintain a normal working temperature, and the service life of the bearing seat can be prolonged. Especially for larger bearing seats, they can also be cooled and temperature-reduced in time.

[0007] As a further improvement of the above technical solution, a first deflector is connected to the outer side of the inner cylinder. A plurality of first deflectors are arranged in a circumferential array around the inner cylinder, and the two vertical plates respectively abut against both sides of the plurality of first deflectors. The plurality of first deflectors divide the cooling cavity into a plurality of flow channels extending along the length direction of the inner cylinder. After the coolant enters the cooling cavity, it can enter the plurality of flow channels respectively for heat exchange. In this way, the flow path of the coolant in the cooling cavity can be increased, thereby improving the heat exchange efficiency.

[0008] As a further improvement of the above technical solution, a first flow guiding gap is respectively arranged between the plurality of first deflectors and the inner side wall of the outer cylinder. The spaces in the cooling cavity between two adjacent first deflectors can be communicated with each other through the first flow guiding gap. In this way, a space for the coolant to flow mutually in two adjacent flow channels can be provided, improving the temperature uniformity in the cooling cavity.

[0009] As a further improvement of the above technical solution, annular covers are respectively connected to the sides of the two vertical plates away from each other. Annular flow guiding cavities are respectively formed between the two annular covers and the inner cylinder. Communication holes are respectively arranged on the two vertical plates, and a plurality of communication holes are arranged around the rotating shaft. The coolant in the cooling cavity can enter and exit the annular flow guiding cavities on both sides of the two vertical plates through the communication holes. In this way, the flow path covered by the coolant can be increased, especially at the position of the bearing end, improving the effect of cooling and temperature reduction of the rotating shaft.

[0010] As a further improvement of the above technical solution, second deflectors are respectively connected to the outer side of the inner cylinder in the two annular flow guiding cavities. A plurality of second deflectors are arranged around the inner cylinder. The plurality of second deflectors can form a plurality of flow blocking structures around the rotating shaft in the annular flow guiding cavity where they are located. In this way, the flow path of the coolant flowing around the rotating shaft in the annular flow guiding cavity can be reduced, and the annular flow guiding cavity is divided into a plurality of heat exchange regions, improving the heat exchange efficiency of the coolant to the bearing end.

[0011] As a further improvement of the above technical solution, a second flow guiding gap is respectively arranged between the plurality of second deflectors and the inner side of the annular cover. The plurality of heat exchange regions divided in the annular flow guiding cavity can be communicated with each other through the second flow guiding gap. In this way, a heat exchange space can be provided for two adjacent heat exchange regions, improving the temperature distribution uniformity at various positions in the annular flow guiding cavity.

[0012] As a further improvement of the above technical solution, the water inlet and the water outlet are respectively located on both sides of the outer cylinder. Cold water enters between the outer cylinder and the inner cylinder from the water inlet, then flows circumferentially around both sides of the inner cylinder, and finally flows outwards from the water outlet. In this way, the flow path of the cold water entering the cooling cavity is designed more reasonably, improving the heat exchange efficiency of the cold water.

[0013] As a further improvement of the above technical solution, a sewage outlet is also provided on the outer cylinder. When operations such as cleaning blockages or changing water inside the cooling chamber are required, the operations can be carried out through the sewage outlet, which can improve the convenience of later use and maintenance.

[0014] As a further improvement of the above technical solution, positioning steps are respectively arranged inside the two end parts of the inner cylinder, and the connecting bearings are respectively connected inside the two positioning steps. When it is necessary to install the connecting bearing between the inner cylinder and the rotating shaft, the positioning steps can be used to quickly install and position the connecting bearing, which can effectively improve the installation efficiency and stability of the connecting bearing.

[0015] As a further improvement of the above technical solution, gland plates are respectively connected to the two ends of the inner cylinder, and the two gland plates respectively press the two connecting bearings into the two positioning steps. After the connecting bearings are installed in place, the two gland plates can be respectively connected to the two ends of the inner cylinder, and the two connecting bearings can be respectively pressed into the two positioning steps through the two gland plates, so that the installation of the connecting bearings is more stable.

Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model. In addition, all the connection relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to specific implementation situations. Each technical feature in the present invention can be combined interactively without conflicting with each other.

[0022] Referring to Figure 1 、 Figure 2 and Figure 3 , a water-cooled bearing housing, comprising: a base 1, inside which two vertical plates 11 are arranged at intervals in the left-right direction, and openings facing each other are respectively arranged on the two vertical plates 11; an outer cylinder 2, which is located between the two vertical plates 11, and a water inlet 21 and a water outlet 22 are arranged on the outer cylinder 2; an inner cylinder 3, which passes through the outer cylinder 2, and both ends of the inner cylinder 3 are respectively located in the two openings, and a support rib 31 is connected between the inner cylinder 3 and the outer cylinder 2; a rotating shaft 4, which passes through the inner cylinder 3, and a connecting bearing 41 is connected between the rotating shaft 4 and the inner cylinder 3.

[0023] In this water-cooled bearing housing, the two vertical plates 11 arranged at intervals in the left-right direction inside the base 1 can form two structures for supporting the inner cylinder 3 to support and fix the inner cylinder 3. The outer cylinder 2 is located between the two vertical plates 11, and the support rib 31 can provide support and positioning for the outer cylinder 2. The rotating shaft 4 is fixed in the inner cylinder 3 through the connecting bearing 41 and can rotate self-driven by an external driving source and drive the external structural parts to rotate, such as a grinding rotor. An annular cooling cavity is formed by enclosing between the outer side of the inner cylinder 3, the inner side of the outer cylinder 2 and the two vertical plates 11. When the rotating shaft 4 works, cold water can be injected into the cooling cavity from the water inlet 21, and the heat conducted from the connecting bearing 41 to the inner cylinder 3 is taken away by the cold water, and then the cooling water is output from the water outlet 22. In this way, through water-cooling, the rotating shaft 4 and the connecting rotating shaft 4 can be cooled in time, so that the entire bearing housing can maintain a normal working temperature and the service life of the bearing housing can be extended. Especially for a relatively large bearing housing, it can also be cooled in time.

[0024] In order to improve the effect of the coolant flowing in the cooling chamber and exchanging heat, in this embodiment, the outer side of the inner tube 3 is connected with a first guide plate 32, and a plurality of the first guide plates 32 are arranged in a circular array around the inner tube 3, and the two vertical plates 11 are respectively against the two sides of the plurality of the first guide plates 32. The plurality of first guide plates 32 divide the cooling chamber into a plurality of flow channels extending along the length direction of the inner tube 3. After the coolant enters the cooling chamber, it can enter the plurality of flow channels for heat exchange, thereby increasing the flow distance of the coolant in the cooling chamber, thereby improving the heat exchange efficiency.

[0025] Furthermore, first guide gaps 33 are respectively provided between the first guide plates 32 and the inner wall of the outer tube 2. The space between two adjacent first guide plates 32 in the cooling cavity can be interconnected through the first guide gaps 33, so that space can be provided for the coolant to flow between two adjacent flow channels, thereby improving the uniformity of the temperature in the cooling cavity.

[0026] In order to further increase the heat exchange and cooling effect of the coolant on the entire connection bearing 41, in this embodiment, the two sides of the vertical plates 11 that are away from each other are respectively connected with an annular cover plate 5, and an annular guide cavity is formed between the two annular cover plates 5 and the inner cylinder 3. The two vertical plates 11 are respectively provided with a connecting hole, and a plurality of the connecting holes are provided around the rotating shaft 4. The coolant in the cooling cavity can enter and exit the annular guide cavity located on both sides of the two vertical plates 11 through the connecting hole, so that the flow coverage of the coolant can be increased, especially at the position of the bearing end, and the cooling effect on the rotating shaft 4 can be improved.

[0027] Similarly, the outer side of the inner cylinder 3 is connected to the second guide plates 34 in the two annular guide chambers, and a plurality of the second guide plates 34 are arranged around the inner cylinder 3. The plurality of second guide plates 34 can form a plurality of flow blocking structures around the rotating shaft 4 in the annular guide chamber, thereby reducing the travel of the coolant flowing around the rotating shaft 4 in the annular guide chamber, dividing the annular guide chamber into a plurality of heat exchange areas, and improving the heat exchange efficiency of the coolant to the bearing end.

[0028] Furthermore, a second flow guide gap is respectively provided between the plurality of the second flow guide plates 34 and the inner side of the annular cover plate 5. The plurality of heat exchange areas divided in the annular flow guide cavity can be interconnected through the second flow guide gap, so that a heat exchange space can be provided for two adjacent heat exchange areas, thereby improving the uniformity of temperature distribution at various locations in the annular flow guide cavity.

[0029] In the above embodiment, the water inlet 21 and the water outlet 22 may be located on the same side of the outer tube 2, but in the present embodiment, the water inlet 21 and the water outlet 22 are respectively located on both sides of the outer tube 2. Cold water enters between the outer tube 2 and the inner tube 3 from the water inlet 21, then flows around both sides of the inner tube 3 in the circumferential direction, and finally flows out from the water outlet 22, so that the path for cold water to flow into the cooling chamber is more reasonably designed to improve the heat exchange efficiency of cold water.

[0030] In some embodiments, the outer cylinder 2 is further provided with a sewage outlet 23. When operations such as clearing blockage or changing water in the cooling chamber are required, the operations can be performed through the sewage outlet 23, which can improve the convenience of later use and maintenance.

[0031] In order to facilitate the quick installation of the connecting bearing 41, in this embodiment, positioning steps 35 are respectively provided in the two ends of the inner cylinder 3, and the connecting bearings 41 are respectively connected to the two positioning steps 35. When the connecting bearing 41 needs to be installed between the inner cylinder 3 and the rotating shaft 4, the positioning steps 35 can be used to quickly install and position the connecting bearing 41, which can effectively improve the efficiency and stability of the installation of the connecting bearing 41.

[0032] In order to better reduce the axial runout of the connecting bearing 41 along the rotating shaft 4 after installation, in this embodiment, the two ends of the inner cylinder 3 are respectively connected with pressure caps 36, and the two pressure caps 36 respectively press the two connecting bearings 41 into the two positioning steps 35. After the connecting bearing 41 is installed in place, the two pressure caps 36 can be respectively connected to the two ends of the inner cylinder 3, and the two connecting bearings 41 can be respectively pressed into the two positioning steps 35 by the two pressure caps 36, so that the connecting bearing 41 is installed more stably.
