[0020] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0021] This application provides a quick-release water-cooled bearing housing, such as... Figure 1 As shown, the water-cooled bearing housing 100 is mounted opposite to each other at both ends of the roller 200 to support the roller 200. The water-cooled bearing housing 100 includes an upper bearing housing 10 and a lower bearing housing 20 arranged opposite to each other. The upper bearing housing 10 and the lower bearing housing 20 are detachably connected to facilitate the replacement of the roller 200.

[0022] like Figures 2-5 As shown, the upper bearing housing 10 has two independent upper bearing cavity 1 and upper water-cooling cavity 2. The opening of the upper bearing cavity 1 is downward. The upper water-cooling cavity 2 surrounds the upper bearing cavity 1 and has an upper water inlet 21 and an upper water outlet 22 that are connected to a water cooling source. The lower bearing housing 20 has two independent lower bearing cavity 3 and lower water-cooling cavity 4. The opening of the lower bearing cavity 3 is upward and can be connected to the opening of the upper bearing cavity 1. The lower water-cooling cavity 4 surrounds the lower bearing cavity 3 and has a lower water inlet 41 and a lower water outlet 42 that are connected to a water cooling source. In this embodiment, both the upper water-cooling cavity 2 and the lower water-cooling cavity 4 are arc-shaped, which can improve the cooling efficiency and cooling effect of the upper bearing cavity 1 and the lower bearing cavity 3.

[0023] The upper water inlet 21, the upper water outlet 22, the lower water inlet 41 and the lower water outlet 42 are located on the same side of the water-cooled bearing seat 100 and are located away from the roller 200; each water inlet and water outlet is provided with a water connection 30, and each water connection 30 is connected with a water pipe, and the water pipe is communicated with a water cooling source. The water pipe can be flexibly bent, which does not affect the opening and closing of the upper bearing seat 10 and the lower bearing seat 20. The upper water inlet 21 and the upper water outlet 22 are arranged opposite to each other, and the lower water inlet 41 and the lower water outlet 42 are arranged opposite to each other, and the cooling water provided by the water cooling source is continuously input into the water-cooled bearing seat 100 from the upper water inlet 21 and the lower water inlet 41, and the cooling water continuously flows through the upper water-cooled cavity 2 and the lower water-cooled cavity 4 to take away the heat in the upper bearing cavity 1 and the lower bearing cavity 2, and the water-cooled bearing seat 100 is output from the upper water outlet 22 and the lower water outlet 42.

[0024] When the bearing sleeved on the shaft head of the roller 200 is installed in the water-cooled bearing seat 100, the bearing is contained in the upper bearing cavity 1 and the lower bearing cavity 3, and when the roller 200 rotates at high speed, the temperature of the bearing and its surrounding area rises, the upper water-cooled cavity 2 and the lower water-cooled cavity 4 are arranged around the periphery of the upper bearing cavity 1 and the lower bearing cavity 3, and the cooling water continuously flows in the inside to reduce the temperature in the upper bearing cavity 1 and the lower bearing cavity 3 in the circumferential direction of the bearing, so as to avoid that the temperature in the bearing cavity is too high to affect the service life and flexibility of the bearing.

[0025] The upper bearing seat 10 and the lower bearing seat 20 are detachably connected by a plurality of connecting bolts (not shown in the figure), and the plurality of connecting bolts are divided into two groups, and the two groups of connecting bolts are arranged opposite to each other.

[0026] As shown in Figure 2 , 6 , a plurality of connecting through holes 5 penetrating the upper bearing seat 10 in the up-down direction are arranged on the upper bearing seat 10, and the plurality of connecting through holes 5 are located outside the upper water-cooled cavity 2; a plurality of threaded holes 6 are arranged on the lower bearing seat 20, and the plurality of threaded holes 6 are located outside the lower water-cooled cavity 4. The plurality of threaded holes 6 correspond to the plurality of connecting through holes 5 one by one, and each connecting bolt is configured to be able to pass through a connecting through hole 5 and be threadedly connected with a corresponding threaded hole 6.

[0027] The water-cooled bearing seat 100 further comprises a positioning pin 40, the bottom of the upper bearing seat 10 is provided with an upper positioning hole 7 for inserting at least part of the positioning pin 40, and the top of the lower bearing seat 20 is provided with a lower positioning hole 8 for inserting at least part of the positioning pin 40, the upper positioning hole 7 and the lower positioning hole 8 are arranged opposite to each other in the up-down direction, and the positioning pin 40 is configured to be able to be inserted into the upper positioning hole 7 and the lower positioning hole 8 at the same time. Through the cooperation between the positioning pin 40 and the upper positioning hole 7 and the lower positioning hole 8, the upper bearing seat 10 and the lower bearing seat 20 can be quickly docked, which is convenient for the quick assembly of the water-cooled bearing seat 100, improves the disassembly and assembly efficiency, and shortens the replacement time.

[0028] The oil inlet hole 9 is located on the upper side of the upper bearing cavity 1 and is in communication with the upper bearing cavity 1, so as to facilitate the operator to add lubricating oil into the water-cooled bearing seat 100 through the oil inlet hole 9. The oil inlet hole 9 and the upper water-cooling cavity 2 are independent of each other.

[0029] When the roller is replaced, only the plurality of connecting bolts are disassembled from the upper bearing seat 10, and the upper bearing seat 10 is moved away from the lower bearing seat 20 to open the bearing cavity, without disassembling the water pipes connecting the upper and lower water-cooling cavities. After the roller is replaced, the upper bearing seat 10 is aligned with the lower bearing seat 20 through the positioning pin 40, and the plurality of connecting bolts are connected one by one to the water-cooled bearing seat 100, so that the replacement of the roller is completed, and the operation is convenient and the replacement time is saved.
