Description

Technical Field

[0001] This utility model relates to a double-layer joint single-layer disengagement torque transmission device, and more particularly to the structure of the torque transmission device. Background Technology

[0002] A single-layer engagement / disengagement torque transmission device is widely used in various mechanical presses to transmit torque and brake driven components.

[0003] Existing torque transmission devices consist of single-layer contact friction pads and single-layer brake friction pads. When a single-layer contact friction pad assembly is insufficient to transmit the rated torque, a larger-sized torque transmission device is selected. Selecting a larger-sized torque transmission device increases both its outer diameter and thickness, resulting in a significant increase in the device's inertia. This weakens the device's braking performance, generates more heat during operation, shortens its lifespan, and increases subsequent maintenance costs.

[0004] In existing torque transmission devices, the thrust friction disc is supported on a spring guide sleeve on one side. The spring guide sleeve is fixed to the transmitter seat. The spring guide sleeve is actually a cantilever beam. When subjected to force for a long time, the spring guide sleeve will be frequently damaged, which will also greatly increase the maintenance cost in the later stage. Summary of the Invention

The friction pads are bonded to both surfaces of a friction pad connecting plate. The friction pad connecting plate is connected to the brake lug via the first bolt assembly and the first nut assembly. The brake sleeve is installed in the inner hole of the brake lug and fixed to the brake lug by the first elastic retaining ring. The brake pin is installed in the inner hole of the brake sleeve. The brake pin fixing plate is installed in the brake pin slot. The engaging friction pad assembly is connected to the active component of the equipment for pressing against the thrust friction disc, floating friction disc, and transmitter seat. The system provides torque transmission. The friction plate assembly includes a friction plate, a friction plate connecting plate, a second bolt group, a second nut group, a connecting ear plate, a connecting sleeve, a second elastic retaining ring, a connecting pin, and a connecting pin fixing plate.

The connecting pin is installed in the inner hole of the connecting sleeve. The connecting pin fixing plate is installed in the connecting pin slot.

[0008] Compared with existing technologies, the beneficial effects of this utility model are as follows: The joint side of this double-layer joint single-layer disengagement torque transmission device is a double-layer joint friction plate group. An additional set of joint friction plates is added to the original torque transmission device. The size of the torque transmission device only increases 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 30%, resulting in significantly less heat generation during operation. This extends the service life of the torque transmission device and reduces subsequent maintenance costs. The spring guide sleeve of the double-layer joint single-layer disengagement torque transmission device has two points of support: the front end of the spring guide sleeve is supported on the brake seat, and the rear end is supported on the transmitter seat. This greatly improves the stress on the spring guide sleeve, reduces damage to the spring guide sleeve, and further reduces subsequent maintenance costs. Due to the above characteristics of this double-layer joint single-layer disengagement torque transmission device, the subsequent maintenance costs of the product can be significantly reduced, and it has broad prospects for widespread application.

The power from the active part is transmitted to the driven part through the engagement friction pad assembly and the double-layer engagement single-layer disengagement torque transmission device. When the compressed air in the sealed cavity composed of cylinder 1, piston 4, first sealing ring 2, and second sealing ring 8 is discharged through port A, it will move to the left due to the force of brake spring 7, thereby pushing piston 4 to the left. This causes the friction disc 26, engagement friction pad assembly, floating friction disc 25, and transmission seat 29 to disengage from each other, and the brake friction pad assembly to engage with the friction surface of brake seat 3. The action of the driven part is achieved by the brake friction pad assembly to achieve braking.
