Novel chain driven type oar

Abstract

The invention discloses a novel chain driven type oar. The novel chain driven type oar is characterized by comprising an engine, a driving shaft, switching shafts and a driven shaft, wherein an engine shaft is connected with the driving shaft through a positive driving device; the driving shaft is connected with the switching shafts through a positive driving device; half of the switching shafts are connected with the driven shaft through a positive driving device; the other half of the switching shafts are connected with the driven shaft through a reverse driving device; and a chain wheel is arranged on the driven device and is connected with an oar sheet. Compared with the prior art, the novel chain driven type oar has the advantages that the same driving shaft can be used, push force of the oar is uniformly distributed on a ship body, and the span and the number of the oars can be correspondingly increased according to the length and the width of a steamship; and when the ship body is steered, the positive driving device and the reverse driving device can be utilized at the same time, the area of a water domain required by steering is small, and the steering speed is high.

Description

【Technical field】 [0001] The invention relates to a paddle, in particular to a novel chain type paddle. 【Background technique】 [0002] At present, most of the ships use propellers, the main defect of which is that the propulsion force is in a straight line, and the ship has a certain width. Therefore, the use of propellers on large hulls has certain limitations, such as: the propulsion force on the hull is not uniform , the turning efficiency of the hull is low, the driving force is insufficient, and the active water area required for turning is relatively large. 【Content of invention】 [0003] In order to solve the above-mentioned deficiencies of the prior art, the present invention provides a novel chain-moving paddle. [0004] The above object of the present invention is achieved by the following technical solutions: a novel chain-moving paddle, characterized in that it comprises an engine, a drive shaft, a conversion shaft and a driven shaft, the engine shaft and the...
