Description

Technical Field

[0001] This utility model relates to the field of retaining ring technology, specifically a retaining ring for a brake. Background Technology

[0002] An electromagnetic brake is a connector that transmits torque from the active side to the passive side. It can be freely engaged, disengaged, or braked as needed. It has advantages such as compact structure, simple operation, sensitive response, long service life, reliable use, and easy remote control.

[0003] Currently, when electromagnetic brakes are installed on the output shaft of a motor, a retaining ring is usually used to limit the bushing to prevent it from moving on the motor output shaft. Existing retaining rings are simple semi-ring bodies. When installing the retaining ring, they mostly rely on their own elastic properties. When it is necessary to install or remove the retaining ring, it is easy for the retaining ring to lose its elasticity and be damaged or fly away and lost. Installation and removal are not easy, and use is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a retaining ring for a brake to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retaining ring for a brake, comprising an upper retaining plate and a lower retaining plate, both of which have contact surfaces arranged inside. The lower end of the upper retaining plate has a first contact groove, and the upper end of the lower retaining plate has a second contact groove. The first contact groove and the second contact groove are in contact with each other. The upper and lower retaining plates are rotatably connected by rivets, and one end of the upper retaining plate and one end of the lower retaining plate are connected by a connecting plate.

[0006] Preferably, the contact surface is semi-annular, and the upper and lower clamping plates are symmetrically arranged.

[0007] Preferably, the top end of the first contact groove and the bottom end of the second contact groove are provided with mounting holes, and the rivet is installed inside the two mounting holes together.

[0008] Preferably, the upper and lower plates have the same thickness.

[0009] Preferably, the upper and lower plates are provided with mounting grooves at their other upper ends, and the connecting plates are installed together inside the two mounting grooves. The bottom of each mounting groove is provided with connecting screw holes. Two connecting screws are installed at one end of the connecting plate through a through hole, and one end of the connecting screw extends into the connecting screw hole.

[0010] Preferably, one end of the connecting plate outside the connecting screw is provided with a receiving hole, and the other end of the connecting screw is located inside the receiving hole.

[0017] 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 protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 3As shown, the brake retaining ring in this embodiment includes an upper retaining plate 1 and a lower retaining plate 2. Both the upper retaining plate 1 and the lower retaining plate 2 are provided with contact surfaces 11. The contact surfaces 11 are used to contact and engage with the retaining ring groove of the motor output shaft. A first contact groove 3 is provided on one side of the lower end of the upper retaining plate 1, and a second contact groove 4 is provided on one side of the upper end of the lower retaining plate 2. The first contact groove 3 and the second contact groove 4 are in contact with each other. The upper retaining plate 1 and the lower retaining plate 2 are rotatably connected by rivets 10. The rivets 10 are installed on the upper retaining plate 1 and the lower retaining plate 2 by a stamping process, thereby achieving a rotatable connection between the upper retaining plate 1 and the lower retaining plate 2, which facilitates the installation of the upper retaining plate 1 and the lower retaining plate 2 in the corresponding retaining ring grooves. One end of the upper retaining plate 1 and one end of the lower retaining plate 2 are connected by a connecting plate 5. The connecting plate 5 is used to connect one end of the upper retaining plate 1 and the lower retaining plate 2 to prevent the upper retaining plate 1 and the lower retaining plate 2 from falling out of the retaining ring groove.

[0020] Specifically, the contact surface 11 is semi-annular, and the upper clamping plate 1 and the lower clamping plate 2 are symmetrically arranged. The shape of the contact surface 11 can fit the shape inside the retaining spring groove. The combination of the upper clamping plate 1 and the lower clamping plate 2 can limit the bushing and effectively prevent the bushing from moving unexpectedly on the output shaft.

[0021] Furthermore, mounting holes are provided at the top of the first contact groove 3 and the bottom of the second contact groove 4. The rivet 10 is installed in both mounting holes. By installing the rivet 10 in the two mounting holes and stamping one end of the rivet 10, the rivet 10 is deformed. The upper clamping plate 1 and the lower clamping plate 2 are rotated through the rivet 10, and the connection between the upper clamping plate 1 and the lower clamping plate 2 will not affect the normal limiting of the bushing.

[0022] Furthermore, the upper clamping plate 1 and the lower clamping plate 2 have the same thickness, and when the upper clamping plate 1 and the lower clamping plate 2 are combined to form a retaining spring, the overall external thickness is the same.

[0023] Furthermore, both the upper and lower plates 1 and 2 have mounting grooves 6 at their other ends. The connecting plate 5 is installed inside both mounting grooves 6. The bottom of each mounting groove 6 has connecting screw holes 7. Two connecting screws 8 are installed at one end of the connecting plate 5 through a through hole. One end of the connecting screw 8 extends into the connecting screw hole 7. The connecting screw 8 is a miniature bolt, and its length is less than the thickness of the upper and lower plates 1 and 2. The shortest bolt length is known to be 0.3 mm, thus ensuring the effectiveness of the connection of the connecting screw 8. By placing the connecting plate 5 into the mounting groove 6 and using the connecting screw 8 to install the connecting plate 5 at one end of the upper and lower plates 1 and 2, the upper and lower plates 1 and 2 are fixed, effectively preventing the retaining spring formed by the upper and lower plates 1 and 2 from accidentally falling out of the retaining spring groove.

[0024] Furthermore, one end of the connecting plate 5 outside the connecting screw 8 is provided with a receiving hole 9, and the other end of the connecting screw 8 is located inside the receiving hole 9. After the connecting screw 8 is installed, one end of the connecting screw 8 is located inside the receiving hole 9, which effectively ensures the flatness of the surface of the connecting plate 5.

[0025] The usage method of this embodiment is as follows: When in use, the bushing in the electromagnetic brake is installed on the output shaft surface of the motor, and the bushing is moved to a suitable position on the output shaft surface. When the snap ring needs to be installed, the upper snap plate 1 is rotated to form a notch between the upper snap plate 1 and the lower snap plate 2, allowing the output shaft to pass through. The contact surface 11 inside the lower snap plate 2 is then brought into contact. The upper snap plate 1 is then rotated to bring the contact surface 11 inside the upper snap plate 1 into contact with the output shaft surface. At this time, the upper snap plate 1 and the lower snap plate 2 are located inside the snap ring groove on the output shaft surface. Then, the connecting plate 5 is placed inside the two mounting slots 6, and the connecting screw 8 is installed inside the connecting screw hole 7 through the connecting plate 5 using a tool. This can achieve the connection and fixation of the upper snap plate 1 and the lower snap plate 2. The upper snap plate 1 and the lower snap plate 2 form a snap ring structure, which limits the bushing and effectively prevents the bushing from moving on the output shaft surface.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
