Torque limiter, transmission system, and method for assembling said torque limiter

A torque limiter, comprising:

• a first ring, the first ring being adapted to be driven to rotate about an rotation axis;
• a second ring that is at a certain distance from the first ring in an axial direction;
• a pressure ring located between the first ring and the second ring in the axial direction;
• a friction disc slidably sandwiched between the second ring and the pressure ring;
• and
• a spring washer axially arranged between the first ring and the pressure ring, the pressure ring receiving a pressing force from the spring washer and pressing the friction disc against the second ring,
• wherein the first ring and the second ring are integrally formed, the first ring is provided with a plurality of first teeth, the spring washer is provided with a plurality of support teeth, and each support tooth is supported by one first tooth, and
• wherein the first ring and the second ring are interconnected by a plurality of connecting bars, the connecting bars being integrally formed with the first ring and the second ring.
