Problems solved by technology

This method has the following disadvantages in previous applications: 1. The equipment layout is large in size and requires a large space
However, the traditional lateral propulsion device changes the rotation direction of the gear shaft through the car clutch. When the steering direction is inconsistent with the rotation direction of the gear, the force on the gear pair is unreasonable, and it is easy to get stuck or generate a large radial force (for the cone gear shaft), which shortens the service life of the gear shaft and gear, and also increases the repair and maintenance costs of the equipment

Abstract

The invention discloses a propeller forward and reverse rotation device of a side thruster. The device comprises a gearbox, a transmission assembly and a propeller, wherein the transmission assembly comprises an input shaft and an output shaft, the input shaft and the output shaft are in transmission connection through bevel gears, the first bevel gear is arranged at the lower end of the input shaft, and a first sleeve and a second sleeve are rotationally arranged on the output shaft. Due to the fact that a double-clutch mode is used on the output shaft, forward and reverse rotation of the output shaft is controlled, and the equipment cost is reduced. Meanwhile, the situation that in the prior art, a reverse device is arranged on the input shaft is avoided, so that reverse rotation of the transmission assembly in the gearbox is avoided, and the service life of the gearbox is prolonged.

Description

technical field [0001] The invention relates to the field of marine equipment, in particular to a forward and reverse device for a propeller of a lateral thruster. Background technique [0002] In traditional lateral thrusters powered by diesel engines, the input shaft of the diesel engine turns in one direction. In order to realize the forward and reverse rotation of the propeller and generate bidirectional thrust, it is necessary to install a clutch device between the side thrusters of the diesel engine to realize the side thrust propeller. Turn clockwise or counterclockwise. This method has the following disadvantages in previous applications: 1. The size of the equipment arrangement is large and requires a large space. 2. The transmission structure in the marine lateral propulsion device generally adopts the spiral bevel gear as the main transmission component. The ideal working state of the spiral bevel gear is that the steering and the rotation direction are consisten...
