Overtaking gear for revolving door drives - has restricted overtaking speed determined by translation of gear wheels

摘要

The overtaking gear has a restricted overtaking speed wherein the drive (1) and driven shaft (2) are connected by two parallel mutually operating free wheel clutches (3,4) and gear wheels (5,6,7,8). The max. overtaking speed of the driven shaft is determined from the translation of the gear wheels. The translation can be multiplied. USE - For revolving door drives whereby the desired overtaking speed can be kept constant.
