Description

Technical Field

[0001] The utility model relates to the technical field of bearings, specifically a bearing with a brake structure. Background Art

[0002] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings.

[0003] However, it is difficult for the bearing to stop quickly after rotating. It will continue to rotate due to inertia, affecting the stable use of the bearing.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a bearing with a brake structure is provided. Utility Model Content

[0005] The purpose of the utility model is to provide a bearing with a brake structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing with a brake structure, comprising an integrated bearing, an output shaft and a cast iron body, brake pads are installed on both sides of the integrated bearing and the output shaft, and a limit stop block is installed on the top of the brake pad, a piston is arranged on one side of the limit stop block, a piston cylinder and front cover plate is installed on one side of the piston, and the cast iron body is arranged on the right side of the piston cylinder and front cover plate.

[0007] Furthermore, the brake pad is arranged around the outer side of the integrated bearing and one end of the output shaft, and the integrated bearing and the output shaft are arranged at the center of the cast iron body.

[0008] Furthermore, the brake pad and the limit stopper are integrated into one structure, and the limit stopper is arranged above the brake pad.

[0009] Furthermore, the brake pad is slidably connected to the inner side of the cast iron body, and the diameter of the brake pad is greater than the length of the piston.

[0010] Furthermore, the bottom of one side of the piston is parallel to the brake pad, and the piston is arranged inside the piston cylinder which also serves as the front cover plate.

[0011] Furthermore, the length of the inner groove of the piston cylinder and front cover plate is greater than the length of the piston, and the width of the piston and the piston assembly is greater than the width of the piston cylinder and front cover plate.

[0012] The utility model provides a bearing with a brake structure, which has the following beneficial effects:

[0013] 1. The utility model uses the integrated bearing and the output shaft to output power, which causes the output shaft to rotate continuously. The piston is pressed down by the piston cylinder and the front cover plate, so that the piston can drive the brake pad to move toward the integrated bearing and the output shaft, so that the brake pad will press against the integrated bearing and the outer surface of the output shaft. Through the friction between the two, the integrated bearing and the output shaft can stop quickly and remain stationary after rotation, and have good stability.

[0014] 2. The utility model adopts the design of the piston and the limit stopper, so that the limit stopper protrudes from the piston and can stably contact the end of the brake pad when the piston is pressed down, thereby achieving stable downward pressure on the brake pad and ensuring that the brake pad is stably in contact with the integrated bearing and the output shaft surface in the downward pressure direction for braking.

[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] like Figure 1 and Figure 2A bearing with a brake structure comprises an integrated bearing and an output shaft 1, a cast iron body 2, a piston cylinder and a front cover plate 3, a piston 4, a brake pad 5 and a limit stopper 6. Brake pads 5 are installed on both sides of the integrated bearing and the output shaft 1, and a limit stopper 6 is installed on the top of the brake pad 5. A piston 4 is arranged on one side of the limit stopper 6. The bottom of one side of the piston 4 is parallel to the brake pad 5, and the piston 4 is arranged inside the piston cylinder and the front cover plate 3. Through the design of the piston 4 and the limit stopper 6, it is convenient to utilize the design of the limit stopper 6 protruding from the piston 4 to stably contact the end of the brake pad 5 when the piston 4 is pressed down, so as to achieve stable downward pressure on the brake pad 5 and ensure that the brake pad 5 is stably in contact with the surface of the integrated bearing and the output shaft 1 in the downward pressure direction. For braking, a piston cylinder and front cover plate 3 is installed on one side of the piston 4, the length of the inner groove of the piston cylinder and front cover plate 3 is greater than the length of the piston 4, and the width of the piston 4 and the piston 4 is greater than the width of the piston cylinder and front cover plate 3, and the cast iron body 2 is arranged on the right side of the piston cylinder and front cover plate 3. The power output through the integrated bearing and the output shaft 1 will cause the output shaft to rotate continuously, and the piston 4 is driven downward by the piston cylinder and front cover plate 3 so that the piston 4 can drive the brake pad 5 to move toward the integrated bearing and the output shaft 1, so that the brake pad 5 will press against the outer surface of the integrated bearing and the output shaft 1, and the friction between the above two makes the integrated bearing and the output shaft 1 stop quickly and remain stationary after rotation, and has good stability;

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the brake pad 5 is surrounded and arranged on the outside of one end of the integrated bearing and the output shaft 1, and the integrated bearing and the output shaft 1 are arranged in the center of the cast iron body 2, the brake pad 5 and the limit stop block 6 are integrated into a structure, and the limit stop block 6 is arranged above the brake pad 5, the brake pad 5 is slidingly connected to the inner side of the cast iron body 2, and the diameter of the brake pad 5 is greater than the length of the piston 4. Through the metal material design of the cast iron body 2, the heat generated by the friction between the brake pad 5 and the integrated bearing and the output shaft 1 can be discharged to the outside, which has a good heat dissipation effect.

[0022] In summary, the bearing with brake structure is firstly based on Figure 1-Figure 3 In the structure shown in the figure, the power output through the integrated bearing and the output shaft 1 will cause the output shaft to rotate continuously, and the piston 4 is pressed down by the piston cylinder and the front cover plate 3 so that the piston 4 can drive the brake pad 5 to move toward the integrated bearing and the output shaft 1, so that the brake pad 5 will press against the outer surface of the integrated bearing and the output shaft 1, and the friction between the above two makes the integrated bearing and the output shaft 1 stop quickly after rotation and remain stationary, with good stability;

[0023] The design of the piston 4 and the limit stopper 6 makes it possible to utilize the design of the limit stopper 6 protruding from the piston 4 to stably contact the end of the brake pad 5 when the piston 4 is pressed down, thereby achieving stable downward pressure on the brake pad 5 and ensuring that the brake pad 5 is stably in contact with the surface of the integrated bearing and the output shaft 1 in the downward pressure direction for braking. Secondly, the metal material design of the cast iron body 2 can guide the heat generated by friction between the brake pad 5, the integrated bearing and the output shaft 1 to the outside, thereby having a good heat dissipation effect.
