Abstract

A rotational ratio-stroke damper for setting-up apparatus is composed of trasmission unit and resistance source. Said transmission unit has a fixing shaft supported by the supporting frame has a big and a small transmission wheels wound by steel cable and with the transmission ratio of (1.1-20):1. The output end of the steel cable wound on the small wheel is connected to resistance source. Its advantages are small size and no need of counterweight.

Description

technical field [0001] The invention relates to a rotary-type variable-ratio stroke damping device in a sports body-building apparatus. Background technique [0002] The damping device is composed of a resistance source and a damping transmission device. It is a key component of fitness equipment and training equipment. There are large-scale strength training equipment and fitness equipment. The long linear distance can reach about two meters. This is because the metal counterweight as the resistance source is not only bulky and inconvenient, but also noisy, and the damping device or system composed of it needs to be equipped with a damping guide bar and a vertical frame of more than two meters. Therefore, it is difficult to enter high-rise buildings or common families with regard to space and cost. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art such as large volume, high cost and high noise, and p...
