| 摘要 |
The invention relates to a speed limiter (17) for an elevator system (100), wherein the speed limiter (17) comprises at least one speed limiter wheel (18a) having a first radial cam (48a) with elevations (40a-40h), and having at least one second, phase-shifted radial cam (48b) with elevations (40a ?40h ?); a first mass (26a), which is rotatably arranged in a first pivot bearing (62a) and which together with a first roller (28a) rolls on the first radial cam (48a) such that the first mass (26a) follows a first oscillating motion when the speed limiter wheel (18a) rotates; and at least one second mass (26b), which is rotatably arranged in a second pivot bearing (62b) and which together with a second roller (28b) rolls on the second radial cam (48b) such that the second mass (26b) follows a second oscillating motion when the speed limiter wheel (18) rotates.
