Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a self-sealing deep groove ball bearing with a split outer ring. Background Art

[0002] Deep groove ball bearing is a common type of rolling bearing, usually composed of inner ring, outer ring, steel ball and cage. Its characteristic is that the contact point between the inner and outer rings is a spherical rolling element, which can bear radial and axial loads, and has high speed capability and wear resistance. This kind of bearing is widely used in mechanical equipment, such as motors, automobile transmission systems, fans, etc.

[0003] The steel balls of current deep groove ball bearings are limited in number due to the limitation of the filling angle of deep groove ball bearings, which leads to insufficient structural stability of the bearings. In addition, in order to ensure the sealing of the bearings, additional sealing structures need to be added, which increases the cost. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a self-sealing deep groove ball bearing with a split outer ring.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] A self-sealing deep groove ball bearing with a split outer ring comprises an outer ring, an inner ring, a retaining frame and a plurality of steel balls. The inner ring is located on the inner side of the outer ring. The inner diameter of the outer ring is adapted to the outer diameter of the inner ring. A receiving groove is provided in the middle of the inner wall of the outer ring. The retaining frame is sleeved on the inner ring and is located in the receiving groove. A plurality of pockets are provided on the retaining frame. The steel balls are arranged in the pockets. The outer ring structure is a split type.

[0007] As a further description of the above technical solution: the outer ring is split into two half outer rings, and a connecting piece is provided at the connection between the two half outer rings, and the half outer rings and the connecting piece are locked by screws.

[0008] As a further description of the above technical solution: the retaining frame adopts an integrated solid retaining frame, and the material of the retaining frame is nylon.

[0009] As a further description of the above technical solution: a curvature surface raceway is arranged on the inner wall of the outer ring and the outer wall of the inner ring.

[0010] As a further description of the above technical solution: the corners of the outer ring and the inner ring are rounded.

[0011] Compared with the prior art, the advantages of the present invention are:

[0012] 1. This solution designs the outer ring into a split structure to facilitate the installation of the outer ring and the installation of the steel balls. The steel balls are not controlled by the filling angle of the deep groove ball bearing. The number of steel balls is increased, which improves the overall load-bearing capacity of the bearing.

[0013] 2. This solution provides a receiving groove on the inner wall of the outer ring for accommodating the retaining frame and the steel ball, thereby enhancing the structural stability of the bearing. The outer ring parts on both sides of the receiving groove form a self-sealing structure, which effectively prevents external dust, dirt or liquid from entering the bearing, thereby improving the working stability and life of the bearing.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 A self-sealing deep groove ball bearing with a split outer ring comprises an outer ring 1, an inner ring 2, a retainer 3 and a plurality of steel balls 4. The inner ring 2 is located on the inner side of the outer ring 1. The inner diameter of the outer ring 1 matches the outer diameter of the inner ring 2. A receiving groove 5 is provided in the middle of the inner wall of the outer ring 1. The retainer 3 is sleeved on the inner ring 2 and located in the receiving groove 5. A plurality of pockets 6 are provided on the retainer 3. The steel balls 4 are arranged in the pockets 6. The outer ring 1 has a split structure.

[0021] In this embodiment, the outer ring 1 is designed to be a split structure, which facilitates the installation of the outer ring 1 and the steel balls 4. The steel balls 4 are not controlled by the filling angle of the deep groove ball bearing, and the number of steel balls 4 is increased, thereby improving the overall load-bearing capacity of the bearing.

[0022] A receiving groove 5 for accommodating the retaining frame 3 and the steel ball 4 is opened on the inner wall of the outer ring 1, which enhances the structural stability of the bearing, and the parts of the outer ring 1 on both sides of the receiving groove 5 form a self-sealing structure, which effectively prevents external dust, dirt or liquid from entering the interior of the bearing, thereby improving the working stability and life of the bearing.

[0023] like Figure 1 , 2 As shown, the outer ring 1 is divided into two half outer rings 11, and a connecting piece 12 is provided at the connection between the two half outer rings 11. The half outer rings 11 and the connecting piece 12 are locked by screws 13. By designing the outer ring 1 as a combined structure, the assembly of the entire bearing is facilitated. It should be noted that the screws 13 are not allowed to be higher than the outer diameter of the outer ring 1.

[0024] In addition, retainer 3 adopts an integrated solid retainer, eliminating the rivet structure and improving production efficiency. The material of retainer 3 is nylon, which is a lightweight material with good mechanical strength, which can help reduce the overall weight of the bearing and has good corrosion resistance. It can resist the corrosion of lubricants and the external environment to a certain extent and maintain the stability and performance of the bearing.

[0025] Furthermore, the inner wall of the outer ring 1 and the outer wall of the inner ring 2 are both provided with a curvature surface raceway 7 to reduce vibration and impact. The corners of the outer ring 1 and the inner ring 2 are rounded to improve the performance and durability of the deep groove ball bearing, reduce damage caused by stress concentration, improve lubrication effect, and reduce noise and vibration levels.

[0026] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
