[0002] A water-cooled bearing seat is a type of bearing seat. It is a bearing seat that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, convenient installation and maintenance. Generally, our water-cooled bearing seats are made of thickened cast steel, which is firm and not easy to wear and damage, has high hardness and a tight structure, thus increasing its service life.

[0003] When using a water-cooled bearing seat, it should be noted that the waste oil in the bearing seat needs to be replaced to ensure good heat dissipation and lubrication.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: a combined water-cooled bearing housing, including a base 1, the top end of the base 1 is fixedly connected with a lower housing 2, the top end of the lower housing 2 is provided with an upper housing 3, one end of the upper housing 3 and the lower housing 2 is provided with a front disc 9, the surface of the front disc 9 is threadedly connected with a fastening bolt 10, the other end of the upper housing 3 and the lower housing 2 is provided with a front disc groove 11, and a bolt groove 12 is arranged inside the front disc groove 11. When multiple water-cooled bearing housings are assembled, the front disc 9 of a certain bearing housing will be embedded inside the front disc groove 11 of another bearing housing, and at the same time, the fastening bolt 10 will be embedded inside the bolt groove 12 to form a tightly matched state, and there is no gap between the two bearing housings after assembly, providing stronger stability for the operation of the bearing housing and preventing the bearing housing from malfunctioning during operation.

[0023] An assembly threaded rod 13 is arranged inside the base 1, the surface of the assembly threaded rod 13 is threadedly connected with an assembly nut 14, and multiple bearing housings can be arranged on the surface of the assembly threaded rod 13 at the same time, enabling the bearing housings to slide on the surface of the assembly threaded rod 13, which can not only prevent the bearing housings from rotating but also facilitate the assembly of the bearing housings. And the assembled bearing housings can be limited by the assembly nut 14 to prevent the bearing housings from falling off after assembly and affecting the operation of the bearings.

[0024] A water outlet 6 is arranged on one side of the lower housing 2, a water inlet 5 is arranged on one side of the upper housing 3, a circulation pipe 7 is fixedly installed on the other side of the lower housing 2 and the upper housing 3, and both the water inlet 5 and the water outlet 6 are connected to a water pump. A cooling water circulation system is formed inside the bearing housing through the water pump, and heat generated during the operation of the bearing is taken away through the heat exchange between the cooling water and the bearing, thereby completing the work of water-cooling the bearing housing.

[0025] A connecting bolt 4 is threadedly connected to the top end of the upper housing 3. The connecting bolt 4 connects the lower housing 2 and the upper housing 3. Through the connecting bolt 4, the lower housing 2 and the upper housing 3 can be very conveniently separated, facilitating the maintenance of the interior of the bearing seat and preventing failures of the bearing seat during operation.

[0026] A water-cooling chamber 8 is provided inside the lower housing 2 and the upper housing 3 after connection. The water-cooling chamber 8 is connected to the water inlet 5 and the water outlet 6.

[0027] The front disc 9 cooperates with the front disc groove 11, and the fastening bolt 10 cooperates with the bolt groove 12. The front disc 9 not only facilitates the installation of the bearing on the bearing seat, but also provides further stability for the connection between the lower housing 2 and the upper housing 3, preventing the bearing seat from falling apart during the heat dissipation process for the bearing.

[0028] Sealing rings 15 are provided at the connection between the front disc 9 and the upper housing 3 and the lower housing 2. The sealing rings 15 can prevent the leakage of cooling water, thus affecting the normal operation of the cooling water circulation system and then affecting the heat dissipation effect of the bearing seat on the bearing.

[0029] Working principle: First, assemble the upper housing 3 and the lower housing 2 of the bearing seat. Then connect the front disc 9 to one end of the bearing seat. Then the bearing can be installed inside the bearing seat. After the bearing starts to operate, the water pump can be started to make the cooling water enter the water-cooling chamber 8 inside the bearing seat from the water inlet 5. Through the heat exchange between the cooling water and the bearing, the heat is taken out from the water outlet 6, and the heat dissipation of the bearing can be completed. When multiple bearing seats need to be assembled, first insert the assembly threaded rod 13 into the inside of the bases 1 of multiple bearing seats. Then make the front disc 9 cooperate with the front disc groove 11. Then tighten the assembly nut 14 to fix the assembled bearing seats, and the assembly of the bearing seats can be completed.
