The invention discloses a labor-saving accelerating device. The device comprises a labor-saving mechanism, a clutch and an accelerating mechanism, the labor-saving mechanism and the accelerating mechanism are arranged on two sides of the clutch; and the labor-saving mechanism comprises an input shaft, a first semicircular gear is additionally arranged at one end of the input shaft, a second semicircular gear is additionally arranged on the other side of the input shaft, one side of the first semicircular gear is connected with a second gear through a meshed third gear, one side of the second gear is meshed with a fourth gear, and the second gear is additionally arranged at one end of a second shaft. Compared with like devices in the prior art, the device of the invention has the followingadvantages: labor saving and acceleration can be realized by increasing or decreasing the number of pulley blocks, connecting acceleration ends in series or in parallel, connecting labor-saving ends in series or in parallel and combining series-parallel connection; the labor-saving mechanism and the acceleration mechanism are freely switched through the clutch, so more labor is saved, the loss caused by parts is small due to speed change, the transmission efficiency is greatly improved, the overall structure is simple and practical, quick-wear parts do not exist, the appearance is attractive and elegant, and installation is convenient and fast.

    本发明公开了一种省力加速装置,包括省力机构、离合器和加速机构,其特征在于:省力机构和加速机构安装在离合器两侧;省力机构包括输入轴,输入轴一端加装有半圆齿轮一,另一侧加装有半圆齿轮二,半圆齿轮一一侧通过啮合的齿轮三连接齿轮二,齿轮二一侧啮合有齿轮四,齿轮二加装在轴二一端。本发明与现有技术相比的优点在于:可以通过增加或减少滑轮组个数、增速端串联或并联、省力端串联或并联、组合串并联、改变皮带轮及齿轮大小实现省力与加速,通过离合器自由切换省力机构和加速机构,更加省力,且速度变换使零部件造成的损耗更小,大大提高了传动效率,整体结构简单实用,无易损件,外形美观大方,安装便捷。
