Description

Technical Field

[0001] This application relates to the field of bearing oil injection technology, and in particular to a bearing oil injection device. Background Technology

[0002] A bearing is a precision mechanical component that transforms the sliding friction between a rotating shaft and its housing into rolling friction, thereby reducing frictional losses. A bearing generally consists of four parts: an inner ring, an outer ring, rolling elements, and a cage. The inner ring primarily mates with the shaft and rotates with it. The outer ring primarily mates with the bearing housing to provide support. The rolling elements are located between the inner and outer rings. The cage separates the rolling elements, distributes them evenly, guides their rotation, and provides lubrication.

[0003] Bearings produced often require grease injection, which is typically performed before the rolling elements are assembled with the outer ring. Currently, bearing grease injection is primarily done manually using a grease gun. This method is difficult to control the amount of grease injected, easily leading to uneven grease distribution. Uneven grease distribution directly affects the bearing's lubrication, operating performance, and service life. Furthermore, this method is time-consuming, thus reducing production efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a bearing oil injection device, which addresses the issues of difficult-to-control and uneven oil injection affecting bearing performance, as well as long injection time and low efficiency. The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: The bearing lubrication device includes: Base plate; The two columns are fixedly mounted on the upper surface of the base plate; the drive cylinder is fixedly connected to the base plate at one end. The lifting plate is connected to the two columns by a sliding structure, and the lower end face of the lifting plate is fixedly connected to the output end of the drive cylinder. The upper oil filling pan is connected to the lifting plate in a fixed structure. The upper oil filling pan has several oil filling ports A evenly arranged along the circumference. The lower oil filling pan is located directly below the upper oil filling pan, and the lower oil filling pan has several oil filling ports B evenly arranged along the circumference. Filling port A and filling port B are used to connect to an external oil pump. Filling port A and filling port B are respectively connected to the upper oil pan and the lower oil pan in a fixed structure.

[0005] Furthermore, a connecting column is fixedly installed on the upper surface of the upper oil filling pan, and the other end of the connecting column is fixedly connected to the lifting plate; the oil filling port A is connected to the upper oil filling pan through the connecting column; the oil filling port B is located on the side wall of the lower oil filling pan and is directly connected to the lower oil filling pan.

[0006] Furthermore, a frustum A is fixedly arranged on the lower end face of the upper oil filling plate, and the side wall of the frustum A is connected to the oil filling port A.

[0007] Furthermore, a frustum B is fixedly arranged on the upper surface of the oil filling pan, and the side wall of the frustum B is connected to the oil filling port B.

[0008] Furthermore, several fixed posts are fixedly installed on the lower end face of the upper oil injection pan along the circumferential direction, and the fixed posts are located on the outer periphery of the frustum A.

[0009] Furthermore, frustum A and frustum B have the same radius.

[0010] The beneficial effects of this utility model are: by setting uniform oil injection ports on the upper and lower oil injection plates, it is ensured that the grease can evenly and quickly cover each rolling element of the bearing, avoiding uneven oil injection caused by manual operation of the oil injection gun, which affects the performance of the bearing. The oil injection method of this device not only increases the uniformity of oil injection, but also improves the oil injection efficiency and reduces production costs. By setting up frustum A and frustum B, it is ensured that the upper oil filling plate can be precisely aligned with the lower oil filling plate when moving downwards, effectively preventing bearing position displacement caused by poor alignment, ensuring oil filling quality, and reducing adjustment and calibration time through rapid alignment, thereby further improving oil filling efficiency.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows: like Figure 1-2As shown, the bearing oil injection device includes a base plate 1. Columns 2 are fixedly mounted on both sides of the upper surface of the base plate 1. A drive cylinder 3 is fixedly mounted on the upper surface of the base plate 1. A lifting plate 4 is mounted on the column 2 in a sliding manner. The lower surface of the lifting plate 4 is fixedly connected to the output end of the drive cylinder 3. An upper oil injection plate 5 is fixedly mounted on one side of the lifting plate 4. Several oil injection ports A6 are evenly arranged along the circumference of the upper oil injection plate 5. A lower oil injection plate 7 is located directly below the upper oil injection plate 5. Several oil injection ports A6 are evenly arranged along the circumference of the lower oil injection plate 7. Dry oil inlet B8; oil inlets A9 and B10 for connecting to an external oil pump, oil inlets A9 and B10 are respectively connected to the upper oil inlet plate 5 and the lower oil inlet plate 7 in a fixed structure; by setting uniform oil inlets on the upper oil inlet plate 5 and the lower oil inlet plate 7, it is ensured that the grease can evenly and quickly cover all rolling elements of the bearing, avoiding uneven oil injection caused by manual operation of the oil gun, which would affect the performance of the bearing. The oil injection method of this device not only increases the uniformity of oil injection, but also improves the oil injection efficiency and reduces production costs.

[0015] It should be noted that the upper end face of the upper oil filling pan 5 is provided with a connecting column 11 in a fixed structure, and the other end of the connecting column 11 is connected to the lifting plate 4 in a fixed structure. This structure enables the upper oil filling pan 5 to move up and down together with the lifting plate 4. The oil filling port A9 is connected to the upper oil filling pan 5 through the connecting column 11, and the oil filling port B10 is located on the side wall of the lower oil filling pan 7 and is directly connected to the lower oil filling pan 7. This structure is mainly used to provide grease to the upper oil filling pan 5 and the lower oil filling pan 7, so as to smoothly inject the grease into the bearing.

[0016] It should be noted that the lower end face of the upper oil filling pan 5 is provided with a truncated cone A12 in a fixed structure, and the side wall of the truncated cone A12 is connected to the oil filling port A6; the upper end face of the lower oil filling pan 7 is provided with a truncated cone B13 in a fixed structure, and the side wall of the truncated cone B13 is connected to the oil filling port B8; by setting truncated cones A and B, it is ensured that the upper oil filling pan is precisely aligned with the lower oil filling pan when it moves downward, effectively preventing the bearing position from shifting due to poor alignment, ensuring the quality of oil filling, and reducing adjustment and calibration time by quickly aligning, thereby further improving the oil filling efficiency.

[0017] Furthermore, several fixing posts 14 are fixedly installed on the lower end face of the upper oil pan 5 along the circumferential direction. The fixing posts 14 are located on the outer circumference of the frustum A12. The installation of this fixing post 14 structure can further fix the bearing and ensure that the bearing position does not shift.

[0018] Furthermore, the truncated cones A12 and B13 have the same radius; this arrangement improves the alignment between the upper oil filling plate 5 and the lower oil filling plate 7, facilitates the docking between the upper and lower oil filling plates, and further ensures the uniformity and accuracy of oil filling.

[0019] The working principle and process of this utility model are as follows: Place the bearing without the outer ring assembled on the upper surface of the lower oil filling pan 7. At this time, the inner ring of the bearing is in contact with the truncated cone B13. Start the drive cylinder 3, which drives the lifting plate 4 to move downward along the column 2. The movement of the lifting plate 4 will also drive the upper oil filling pan 5 to move downward until the truncated cone A12 and the truncated cone B13 are in close contact. At this time, the fixing column 14 abuts against the fixing frame between the two rolling elements of the bearing, and the bearing is completely fixed. Start the external oil pump, and grease can be injected into the surface of each rolling element of the bearing through the oil filling port A6 and oil filling port B8 on the side wall of the truncated cone. Then start the drive cylinder 3 again to raise the lifting plate 4. The rise of the lifting plate 4 will drive the upper oil filling pan 5 to rise together. The upper oil filling pan 5 separates from the lower oil filling pan 7. Then, the bearing with oil filling can be taken out.
