AI Technical Summary
选大一规格的扭矩传递装置的外径和厚度方向都会增加一档，使得扭矩传递装置的惯量会成倍增加，会造成设备制动性能的减弱，在工作时会产生更多的热量，因此扭矩传递装置的使用寿命会缩短，增加了后期的维护成本
[0007]与现有技术相比，本实用新型的有益效果是：由于离合侧为双层离合摩擦片，仅在原扭矩传递装置上增加了一组离合摩擦片，扭矩传递装置的尺寸也就厚度方向上有增加，外径尺寸不变，因此扭矩传递装置的传递扭矩增加一倍，但扭矩传递装置的惯量仅增加了35％，在工作时产生的热量也会少很多，这样扭矩传递装置的使用寿命也会变长，后期的维护成本也会大大降低。该实用新型的离合侧的离合摩擦片和内齿圈通过花键联接并作相对轴向移动，由于内齿圈材质为钢件，离合摩擦片材质为含金属成分的复合材料，这种材料在高速运转时，与钢件碰撞时会起到一定的缓冲作用，碰撞时产生的噪音和磨损会大大的降低。由于以上特点，可大幅度降低产品的后期维护成本，具有广阔的推广应用前景。

Abstract
Description
Technical Field
[0001] This utility model relates to a torque transmission device, and more particularly to the structure of the torque transmission device. Background Technology
[0002] Existing torque transmission devices consist of a single-layer clutch friction plate assembly. When this assembly is insufficient to transmit the rated torque, a larger-sized torque transmission device is selected. Selecting a larger-sized device increases both the outer diameter and thickness, resulting in a significant increase in the device's inertia. This weakens the equipment's braking performance, generates more heat during operation, shortens the device's lifespan, and increases subsequent maintenance costs.
[0003] In existing torque transmission devices, the clutch friction plate assembly is guided by guide pins and guide sleeves. Since the guide pins and guide sleeves are made of steel and there is a gap between them, they will collide during high-speed operation. The collision will generate noise and wear, and will also increase the maintenance cost later. Utility Model Content
[0004] This invention provides a torque transmission device for a high-speed press with a double-layer friction plate, which aims to solve the above-mentioned problems.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model includes: a clutch seat, a brake seat, a connecting screw assembly, an O-ring, an inner sealing ring, an outer sealing ring, a piston, a brake spring, and a friction disc; the O-ring is installed in the sealing groove of the clutch seat; the clutch seat and the brake seat are connected by the connecting screw assembly; the inner sealing ring is installed in the groove of the inner circle of the piston; the outer sealing ring is installed in the groove of the outer circle of the brake seat; the O-ring, inner sealing ring, and outer sealing ring are used to seal the compressed air in the sealing cavity formed by the brake seat and the piston; the piston is connected to the clutch seat by a spline and moves axially relative to it; the brake spring is installed in the countersunk hole of the clutch seat, with one end pressing against the clutch seat and the other end pressing against the piston; the friction disc is connected by a spline... The system is connected to a clutch seat and allows for relative axial movement; it also includes a clutch friction pad assembly and a brake friction pad assembly; the clutch friction pad assembly includes a clutch friction pad and an internal gear ring; the clutch friction pad is splined to the internal gear ring and allows for relative axial movement; the brake friction pad assembly includes a brake friction pad, a brake fixing plate, a brake guide sleeve, a guide sleeve retaining ring, a brake guide pin, and a guide sleeve fixing flange; the brake friction pad is bonded to two planes of the brake fixing plate; the brake guide sleeve is installed in the inner hole of the brake fixing plate and fixed to the brake fixing plate by the guide sleeve retaining ring; the brake guide pin is installed in the inner hole of the brake guide sleeve; the inner countersunk hole of the guide sleeve fixing flange is installed on the step of the brake guide pin.
[0007] Compared with existing technologies, the beneficial effects of this utility model are as follows: Because the clutch side uses a double-layer clutch friction plate, only one additional set of clutch friction plates is added to the original torque transmission device. The size of the torque transmission device increases only in the thickness direction, while the outer diameter remains unchanged. Therefore, the transmitted torque of the torque transmission device doubles, but the inertia of the torque transmission device only increases by 35%. The heat generated during operation is also significantly reduced, thus extending the service life of the torque transmission device and greatly reducing subsequent maintenance costs. In this utility model, the clutch friction plate and the internal gear ring on the clutch side are connected by a spline and move axially relative to each other. Since the internal gear ring is made of steel and the clutch friction plate is made of a composite material containing metal components, this material provides a certain buffering effect when colliding with the steel component at high speeds, greatly reducing noise and wear during collisions. Due to these characteristics, the subsequent maintenance costs of the product can be significantly reduced, and it has broad prospects for widespread application. Attached Figure Description

[0009] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0010] Depend on Figure 1As can be seen, this utility model includes: a clutch seat 2, a brake seat 1, a connecting screw assembly 10, an O-ring 11, an inner sealing ring 8, an outer sealing ring 7, a piston 3, a brake spring 5, and a friction disc 4; the O-ring 11 is installed in the sealing groove of the clutch seat 2; the clutch seat 2 and the brake seat 1 are connected by the connecting screw assembly 10; the inner sealing ring 8 is installed in the groove of the inner circle of the piston 3; the outer sealing ring 7 is installed in the groove of the outer circle of the brake seat 1; the O-ring 11, the inner sealing ring 8, and the outer sealing ring 7 are used to seal the compressed air in the sealing cavity formed by the brake seat 1 and the piston 3; the piston 3 is connected to the clutch seat 2 by a spline and moves axially relative to it; the brake spring 5 is installed in the countersunk hole of the clutch seat 2, with one end pressing against the clutch seat 2 and the other end pressing against the piston 3; the friction disc 4 is connected by a spline... The system is connected to the clutch seat 2 and moves relative to it axially; it also includes: a clutch friction plate assembly and a brake friction plate assembly; the clutch friction plate assembly includes a clutch friction plate 9 and an internal gear ring 6; the clutch friction plate 9 is connected to the internal gear ring 6 via a spline and moves relative to it axially; the brake friction plate assembly includes: a brake friction plate 12, a brake fixing plate 13, a brake guide sleeve 15, a guide sleeve retaining ring 14, a brake guide pin 16, and a guide sleeve fixing flange 17; the brake friction plate 12 is bonded to two planes of the brake fixing plate 13; the brake guide sleeve 15 is installed in the inner hole of the brake fixing plate 13 and fixed to the brake fixing plate 13 by the guide sleeve retaining ring 14; the brake guide pin 16 is installed in the inner hole of the brake guide sleeve 15; the inner countersunk hole of the guide sleeve fixing flange 17 is installed on the step of the brake guide pin 16.
[0011] The clutch friction plate assembly is connected to the active component of the device and is used to provide torque transmission when the piston 3, friction disc 4 and clutch seat 2 are pressed together.
[0012] The brake friction pad assembly is connected to the fixed bracket of the equipment and is used to provide braking torque when the thrust piston 3 and the brake seat 1 are pressed together, so as to realize braking of the driven component.
[0013] The working principle of this utility model is as follows: When compressed air from the outside enters the sealed cavity composed of brake seat 1, piston 3, O-ring 11, inner sealing ring 8, and outer sealing ring 7 through inlet A, it pushes piston 3 to move to the right, thereby overcoming the force of brake spring 5 and moving to the right, causing the brake friction pad assembly to disengage from the friction surface of brake seat 1. The thrust clutch friction pad assembly, friction disc 4, and clutch seat 2 friction surface engage. The power from the driving part is transmitted to the driven part through the clutch friction pad assembly and the new double-layer friction pad type high-speed press special torque transmission device. When the compressed air in the sealed cavity composed of brake seat 1, piston 3, O-ring 11, inner sealing ring 8, and outer sealing ring 7 is discharged through port A, it will move to the left due to the force of brake spring 5, thereby pushing piston 3 to the left, causing the clutch friction pad assembly, friction disc 4, and clutch seat 2 friction surface to disengage. The brake friction pad assembly and brake seat 1 friction surface engage. The action of the driven part is achieved by the brake friction pad assembly.
