The invention relates to a speed monitoring device (41) for measuring the number of revolutions or the rotational speed of a main drive shaft (27) of a person transport system (1). For this purpose, the speed monitoring device has at least one rotational speed sensor (43) with an input shaft (45), a pinion (47), and an acquisition device (49) which is designed to be arranged on a shaft housing surface (39) of a main drive shaft (27) of the passenger transport system (1), the rotational speed of which needs to be measured. Furthermore, a support (61) is provided for fixing the revolution sensor (43) and the pinion (47) in a position fixed relative to the rotational axis of the acquisition device (49), the acquisition device (49) having an engagement (53) which can be coupled to the pinion (47) in a rotationally transmitting manner, and the pinion (47) is rotatably mounted in the support (61) in two bearing positions (55, 57).
本发明涉及一种用于测量人员运送设备(1)的主驱动轴(27)的转数或转速的速度监测装置(41)。为此,速度监测装置具有至少一个带有输入轴(45)的转数传感器(43)、小齿轮(47)和采集装置(49),该采集装置被构造用于,能够布置在人员运送设备(1)的需要测量其转数的主驱动轴(27)的轴壳面(39)上。还设有支架(61),用于将转数传感器(43)和小齿轮(47)固定在与采集装置(49)的转动轴相对位置固定的位置上,其中,采集装置(49)具有啮合部(53),该啮合部能够与小齿轮(47)以传递转动的方式联接,并且小齿轮(47)在支架(61)中可转动地支承在两个轴承位置(55、57)中。
