Description

Technical Field

[0001] This utility model relates to the field of bearing housings, specifically a quick-locking type roll bearing housing device for a frameless rolling mill. Background Technology

[0002] Bearing housings are mechanical components used to install, fix, and support bearings, typically serving as connectors between the bearings and the equipment structure. Their main functions are to provide a stable support environment for the bearings, protecting them from external contamination and impact, while facilitating bearing installation, disassembly, and maintenance. The quick-locking roll bearing housing device in a frameless rolling mill is a key component of modern rolling mills, enabling rapid replacement, locking, and positioning of the roll bearing housing, thereby improving production efficiency and simplifying maintenance operations.

[0003] In the prior art, such as in CN202937633U, a bearing housing device for a solar tracking system is disclosed. It includes a lower bearing housing base and an upper bearing housing cover. A rotating shaft is provided between the lower bearing housing base and the upper bearing housing cover. A self-aligning roller bearing is fixed on the outer side of the rotating shaft by a locking sleeve and a positioning ring. The characteristic is that a bearing housing main sealing ring and a rotating rubber ring are arranged sequentially from the inside to the outside on the rotating shaft on both the front and rear sides of the self-aligning roller bearing.

[0004] While the aforementioned patent significantly reduces or even eliminates dust and sand intrusion caused by harsh external environments by sequentially arranging the main bearing housing seal and rotating rubber ring from the inside to the outside on both sides of the self-aligning roller bearing's rotating shaft, and this bearing housing device for the solar tracking system has the advantage of being less prone to jamming and ensuring normal system stability, it also presents challenges. Firstly, the bearing housing is not convenient for moving the bearing to different rotating shaft positions, reducing its applicability. Secondly, the bearing requires regular lubrication to reduce friction and extend its lifespan, and the bearing housing does not facilitate continuous lubrication of the internal balls, further reducing its ease of use. Therefore, to address these issues, a quick-locking roll bearing housing device for a frameless rolling mill is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, the quick-locking roll bearing seat device of the frameless rolling mill includes a lower fixed plate 1, a movable component 2 threadedly connected to the bottom of the lower fixed plate 1, a bearing structure 3 fixedly connected to the top of the lower fixed plate 1, an upper fixed plate 4 fixedly connected to the top of the bearing structure 3, a lubrication component 5 fixedly connected to the top of the upper fixed plate 4, a connecting bolt 6 threadedly connected to the edge of the surface of the upper fixed plate 4, and a lower fixed plate 1 threadedly connected to the surface of the connecting bolt 6.

[0025] The moving component 2 includes a moving plate 201 threadedly connected to the bottom of the lower fixed plate 1. A threaded cylinder 202 is connected through one side of the moving plate 201. A threaded rod 205 is threadedly connected to the surface of the threaded cylinder 202. A transmission rod 203 is fixedly connected to one end of the threaded rod 205. One end of the transmission rod 203 is splinedly connected to the output end of the servo motor 204.

[0026] The lubrication assembly 5 includes an oil tank 501 fixedly connected to the top of the upper fixed plate 4. The bottom of the oil tank 501 is provided with a conical opening. The upper fixed plate 4 is connected through the surface of the conical opening. A drip pipe 502 is connected through the bottom of the conical opening. An oil filling pipe 503 is connected through the top of the oil tank 501. A sealing cap 504 is threadedly connected to the surface of the oil filling pipe 503.

[0027] During operation, thanks to the structural design of the moving component 2, the servo motor 204, when energized, causes the transmission rod 203 to drive the threaded rod 205 to rotate. The threaded cylinder 202, threadedly connected to the threaded rod 205, pushes the moving plate 201 along the threaded rod 205, thereby moving the upper structure of the threaded rod 205. This allows the bearing housing device to move the bearing for use in different equipment, improving its applicability. Through the structural design of the lubrication component 5, the user opens the sealing cover 504 and adds lubricating oil to the oil tank 501 via the oil filling pipe 503. Under gravity, the lubricating oil flows through the conical opening to the inlet of the dripping pipe 502, continuously dripping between the outer cylinder 303 and the inner cylinder 305 to lubricate the balls 304. This allows the bearing housing device to continuously lubricate the balls 304 inside the bearing without disassembly, improving the convenience of using the bearing housing device.

[0028] Furthermore, the bearing structure 3 includes a lower outer shell 301 fixedly connected to the top of the lower fixed plate 1, an upper outer shell 302 overlapping the top of the lower outer shell 301, an outer cylinder 303 fixedly connected to one side of the lower outer shell 301, a ball bearing 304 rollingly connected to the surface of the outer cylinder 303, an inner cylinder 305 rollingly connected to the surface of the ball bearing 304, and a drip tube 502 penetratingly connected to the surface of the outer cylinder 303.

[0029] During operation, the bearing structure 3 supports the rotating parts and bears the load. At the same time, the ball array 304 enables the bearing to reduce the friction generated by the rotation of the inner cylinder 305 through rolling friction while providing higher load-bearing capacity.

[0030] Furthermore, a sealing plate 7 is rotatably connected to one side of the inner cylinder 305, and an outer cylinder 303 is fixedly connected to one side of the sealing plate 7.

[0031] During operation, the enclosed plate 7 provides a closed environment for the balls 304 between the outer cylinder 303 and the inner cylinder 305, thereby improving the service life of the bearing structure 3.

[0032] Furthermore, a rotating shaft 8 is rotatably connected to the surface of the movable plate 201, a guide plate 9 is rotatably connected to the surface of the rotating shaft 8, a platform 10 is fixedly connected to one end of the guide plate 9, and a vertical plate 11 is fixedly connected to the top edge of the platform 10.

[0033] During operation, by changing the installation height of the platform 10, the movable height of the bearing seat device can be changed. At the same time, the rotational connection between the rotating shaft 8 and the guide plate 9 allows the guide plate 9 to improve the stability of the moving plate 201 while reducing the friction between the rotating shaft 8 and the guide plate 9 through rolling friction.

[0034] Furthermore, a transmission rod 203 is continuously connected to the surface of the vertical plate 11, and a threaded rod 205 is rotatably connected to one side of the vertical plate 11.

[0035] During operation, the vertical plate 11 is used to support one end of the threaded rod 205, thereby improving the overall stability of the device.

[0036] Furthermore, a motor housing 12 is fixedly connected to the surface of the servo motor 204, and a platform 10 is fixedly connected to the bottom of the motor housing 12.

[0037] During operation, the servo motor 204 is protected by the settings of the motor box 12.

[0038] Working principle: Before using the bearing housing device, the user opens the sealing cover 504 and adds lubricating oil to the oil tank 501 through the oil filling pipe 503. Under the action of gravity, the lubricating oil flows through the conical opening to the inlet of the dripping pipe 502, and continuously drips into the space between the outer cylinder 303 and the inner cylinder 305 to lubricate the balls 304. This allows the bearing housing device to continuously lubricate the balls 304 inside the bearing without disassembly. Then, the user powers on the servo motor 204, causing the transmission rod 203 to drive the threaded rod 205 to rotate. The threaded cylinder 202, which is threadedly connected to the threaded rod 205, pushes the moving plate 201 to move along the threaded rod 205, thereby moving the structure above the threaded rod 205. At the same time, the rotating shaft 8 rolls on the guide plate 9 to assist the moving plate 201 in moving, bringing the bearing structure 3 to the appropriate position.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
