摘要：NOVELTY - The device has a transmission gear connected with an uplink escalator. A downlink escalator driving gear is connected with a transmission chain wheel. The transmission gear, the transmission chain wheel, an electric motor and a speed reducer system are connected together through a power main shaft. The transmission gear and the transmission chain wheel are provided with a specific transmission ratio. The electric motor is connected between the transmission gear and a transmission chain main shaft or connected with a power transmission gear. USE - Human gravitational potential energy escalator transmission device. ADVANTAGE - The device performs descending escalator abortion function in a proper manner so as to save potential energy at downlink time, so that a set down lift can be driven during positive and negative transmission operation. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a human gravitational potential energy escalator transmission device.
