SINGLE-ANCHOR WINDLASS Russian patent published in 2025 - IPC B63B21/24 

FIELD: ships and other floating facilities.

SUBSTANCE: invention relates to ship machine building, particularly, to single-anchor windlass for large-gauge anchor chain. Windlass comprises anchor chain sprocket mounted freely on shaft and coupled with shaft by coupling. Sprocket shaft is installed on two support posts fixed on the deck foundation. On one of the posts there is an axle rigidly fixed, on which a warping machine is freely installed on bearings. On the same post there is a bracket, to which a motor-reducer is fixed, which consists of an electric motor and a wave gear transmission. Drive sprocket of chain transmission is fixed on output shaft of motor-reducer, which is connected with two driven sprockets by multi-row chain. One driven sprocket is fixed on the rear side of the warping machine body and coaxially with it, the other driven sprocket is fixed on the end of the shaft of the anchor chain sprocket. Windlass drive consists of motor-reducer with compact and small weight of wave gear transmission, simple chain transmission, in which one drive sprocket is connected by chain with two driven sprockets.

EFFECT: reduction of weight and dimensions of windlass design.
