Problems solved by technology

However, it is extremely difficult to predict the magnitude of the wave impact load (because it is a natural object)
[0008] On the other hand, since the case is a heavy and large part, taking measures such as increasing the thickness only to increase the strength will lead to a significant increase in the weight of the overall reduction gear.
In the case of a reduction gear for a ship, the overall weight increases significantly, which not only increases the cost, but also makes it very inconvenient to operate when installed on the deck, or (there are also cases where multiple units are installed), which becomes the main cause of destroying the balance of the hull.

Abstract

The present invention provides a speed reducer for use in a ship and a speed reducer with a motor. When the speed reducer for use in the ship restrains the weight to a smallest limit, the speed reducer has enough strength for stronger wave impact load. According to the speed reducer (G1) equipped on a deck (10) of the ship according to the invention, when the speed reducer (G1) is equipped on the deck (10), at least an upper surface (50) of the speed reducer (G1) is provided with an inclined surface (50A) and an inclined surface (50B) which downwards incline to the outside (end side) when inner side (central side) of the upper surface (50) is overlooked.

Description

technical field [0001] The invention relates to a deceleration device for ships and a deceleration device with motor for ships. Background technique [0002] The deck of the ship is equipped with driving equipment for mooring or loading and unloading. [0003] Patent Document 1 discloses an anchor cable coiler for winding up an anchor cable to which an anchor is connected. Patent Document 2 discloses a mooring winch including a take-up drum for winding a mooring line. [0004] These ship drive devices have a structure in which the rotation of the drive source is decelerated by a reduction gear to increase to a predetermined torque based on the relationship between the rotation of the drive source such as a motor or an engine and the required torque. [0005] Patent Document 1: Japanese Unexamined Patent Publication No. 2002-114489 ( figure 1 ) [0006] Patent Document 2: Japanese Patent Laid-Open No. 2010-111514 ( figure 1 ) [0007] A reduction gear mounted on the dec...
