The invention relates to a torque storing and releasing device of a lifting electric cylinder, which comprises a gear box, a first fixed gear shaft, a second fixed gear shaft, a coil spring gear shaft, a movable tightening gear shaft, a movable counter-rotating gear shaft and a second outer spline shaft, a coil spring is further arranged on the coil spring gear shaft, long arc track holes are formed in the gear box, the movable tightening gear shaft and the movable counter-rotating gear shaft are installed in the long arc track holes respectively, and when the movable tightening gear shaft and the movable counter-rotating gear shaft move along the long arc track holes respectively, the movable tightening gear shaft and the movable counter-rotating gear shaft are tightened. And gears on the movable tightening gear shaft and the movable counter-rotating gear shaft can respectively enter or break away from meshing transmission with the transmission gear set. Early-stage torsion kinetic energy of the lead screw can be stored in the coil spring in the form of torsion elastic potential energy when the electric cylinder returns, and the torsion elastic potential energy is reversely released back to the lead screw in real time when the electric cylinder is lifted, so that the starting speed and acceleration of the electric cylinder are increased.
本发明涉及一种举升电动缸的扭矩存释器,包括齿轮箱、第一固定齿轮轴、第二固定齿轮轴、卷簧齿轮轴、活动上紧齿轮轴、活动反转齿轮轴和第二外花键轴,第一固定齿轮轴、第二固定齿轮轴和卷簧齿轮轴上设有传动齿轮组,卷簧齿轮轴上还设有卷簧,齿轮箱上开设长弧轨道孔,活动上紧齿轮轴和活动反转齿轮轴均安装在各自的长弧轨道孔内,当活动上紧齿轮轴和活动反转齿轮轴沿各自的长弧轨道孔移动时,活动上紧齿轮轴和活动反转齿轮轴上的齿轮能够各自进入或脱离与传动齿轮组的啮合传动。本发明可将电动缸返程时丝杠的前期扭转动能以扭转弹性势能的形式存储在卷簧中,并在举升时将扭转弹性势能反向即时释放回丝杠,以增大电动缸的启动速度及加速度。
