Description

Technical Field

[0001] This utility model relates to the field of electromagnetic braking technology of electromagnetic clutches, specifically a dual-flange type electromagnetic clutch and brake assembly. Background Technology

[0002] The double-flange type electromagnetic clutch and brake combination is based on the principle of electromagnetic induction and the friction between the inner and outer friction plates. Electromagnetic clutches and electromagnetic brakes are ideal automated actuators in modern industry. In mechanical transmission systems, they mainly transmit power and can be used to control the engagement, starting, disengaging, reversing, speed regulation, and braking of machinery. They are widely used in various machine tools and mechanical transmission systems.

[0003] However, in the existing technology, the guide seat for the dual-flange electromagnetic clutch and brake combination is set separately for the clutch and the brake, which not only increases the cost and assembly complexity, but more importantly, the gap between the clutch suction plate and the friction surface cannot be adjusted after assembly.

[0004] Therefore, a dual-flange electromagnetic clutch and brake combination is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a dual-flange type electromagnetic clutch and brake assembly to solve the problems mentioned in the background art.

However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0019] For examples, please refer to Figure 1-4 This utility model provides a technical solution: A dual-flange electromagnetic clutch and brake assembly includes a left flange 1, a left bearing 2 embedded in the inner wall of the left flange 1, a housing 3 mounted on the outer wall of the left flange 1, a right flange 4 mounted at the port of the housing 3, an input shaft sleeve 5 rotatably connected to the inner wall of the left bearing 2, a key bar 6 mounted on the outer wall of the input shaft sleeve 5, a clutch coil seat 7 mounted on the outer wall of the left flange 1, a clutch rotor 8 rotatably connected to the inner wall of the clutch coil seat 7, and a clutch suction plate 9 mounted on the outer wall of the clutch coil seat 7.

[0020] In this embodiment, a left retaining ring 10 is provided on one side of the clutch suction plate 9 and on the outer wall of the clutch coil seat 7, a right retaining ring 11 is provided on the outer wall of the clutch coil seat 7, a left retaining ring 12 is provided between the left bearing 2 and the clutch coil seat 7 and on the outer wall of the clutch coil seat 7, an output shaft 13 is installed at the port of the input shaft sleeve 5, a six-part guide seat 14 is installed on the outer wall of the output shaft 13, and a key bar 15 is installed in the inner cavity of the six-part guide seat 14 and on the outer wall of the output shaft 13.

[0021] In this embodiment, a bearing spacer 16 is installed on the outer wall of the input shaft sleeve 5, a right bearing 17 is installed on the outer wall of the bearing spacer 16, a right retaining ring 18 is installed on the outer wall of the right bearing 17, a right flange 4 is rotatably connected to one end of the right bearing 17, a bearing ring 19 is installed on the outer wall of the output shaft 13, and a right bearing 20 is installed on the outer wall of the bearing ring 19.

[0022] In this embodiment, a brake coil seat 21 is installed on the inner wall of the right flange 4, and a brake suction pad 22 is installed on the outer wall of the brake coil seat 21, wherein the brake suction pad 22 is located on one side of the six-part guide seat 14.

[0023] Among them, the left flange 1 and the right flange 4 are located at opposite ports of the housing 3, the left bearing 2 is located on one side of the key strip 6, one end of the right snap ring 18 is connected to the brake coil seat 21, the six-equal guide seat 14 is composed of two three-equal guide seats spliced ​​together, and the outer wall of the six-equal guide seat 14 is provided with M6 through holes in sequence.

[0024] Based on the above structural features and connection relationships, the clutch plate 9 is fastened to the positioning pin by screws, and then the positioning pin is placed into the through hole of the three-equal guide seat 12.1. After adjusting the clearance, the positioning pin is locked by screws through the M6 ​​through hole on the side, thereby fastening the clutch plate 9 to this six-equal guide seat 14. The advantage of this structural design is that the two guide seats in the original structure are designed into a six-equal guide seat 14, which reduces the number of parts, thus reducing costs, processing and assembly time. The biggest advantage is that by loosening the screws in the M6 ​​through hole on the side, the friction clearance can be adjusted to ensure that it is not too large. The working process of this utility model is as follows: When the double-flange electromagnetic clutch and brake assembly designed using this scheme is in operation, the original two guide seats are designed as a single unit with six equal divisions. The six-divided guide seat 14 is composed of two three-divided guide seats spliced ​​together. One of the three-divided guide seats connects to the brake suction plate 22, which has a fixed gap and does not require adjustment. The other three-divided guide seat connects to the clutch suction plate 9. The side of the three-divided guide seat connecting to the clutch suction plate 9 has an M6 through hole. The clutch suction plate 9 is fastened to the positioning pin with screws. Then, the positioning pin is inserted into the through hole of the three-divided guide seat 12.1, the gap is adjusted, and then screws are used to tighten the M6 ​​through hole on the side. The locking pin secures the clutch plate 9 to the six-part guide seat 14. The advantage of this design is that it transforms the original two guide seats into a single six-part guide seat 14, reducing the number of parts, thus reducing costs, processing, and assembly time. The biggest advantage is that the friction clearance can be adjusted by loosening the screws in the M6 ​​through holes on the side, ensuring that the torque does not decrease during magnetic connection due to excessive clearance. This helps to solve the problem in the existing double-flange electromagnetic clutch and brake combination where each part has its own guide seat, which not only increases costs and assembly complexity but, more importantly, prevents adjustment of the clearance between the clutch plate and the friction surface after assembly.

[0025] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.
