Problems solved by technology

The output of the former is not a standard sinusoidal curve, and the error with the sinusoidal curve is relatively large; the latter achieves swing through the motor commutation, but because the motor keeps reversing, the service life and reliability of the gear cannot be guaranteed, and the The gap caused by the large error in the output results
Moreover, the existing eccentric workbench cannot adjust the eccentric angle from 0°, and the output cannot be fully adjusted (usually only from 10°)

Embodiment

[0031] Example: see figure 1 and figure 2 , a sinusoidal rocking mechanism, including a base, the base has a horizontal bearing platform 1, the bearing platform is supported by at least three supports 14 capable of adjusting the height, adopts a stable structure with three points to determine the plane, and is more stable during adjustment. Easy to level the carrying platform. One end of the carrying platform is fixed with a first support frame 2, and the first support frame includes a base plate fixed with the carrying platform and a mounting plate vertically arranged on the base plate and fixed with the base plate, and a motor and a motor are installed on one side of the mounting plate. A motor reducer connected to the motor, the output shaft of the motor reducer passes through the mounting plate and is connected to an eccentric gear mechanism 3, and the motor drives the eccentric gear mechanism to rotate through the motor reducer. The motor and motor reducer adopt DC mot...

Abstract

The invention discloses a sine swing mechanism which comprises a base. The base is provided with a horizontal bearing platform, a first supporting frame is fixed at one end of the bearing platform, the first supporting frame comprises a vertically arranged mounting board which is provided with a motor and a motor reducing gear, an output shaft of the motor reducing gear penetrates through the mounting board and is connected with an eccentric mechanism, and the eccentric mechanism comprises a sliding nut which is connected with a connecting rod mechanism and drives the connecting rod mechanism to move; supporting boards are symmetrically arranged on two sides of the other end of the bearing platform, a working platform is arranged between the two supporting boards, and a sling rod is arranged below the working platform; one end of a connecting rod far away from a rectangular frame is connected with the sliding rod and drives the sliding rod and the working platform to rotate; and a rotating shaft on one side of the working platform penetrates through the supporting boards, and an encoder is mounted at one end of the rotating shaft far away from the working platform. The sine swing mechanism has the advantages of being simple in structure, stable and reliable and high in output accuracy.

Description

technical field [0001] The invention relates to an experimental device for simulating sea waves for fin stabilizers, in particular to a sinusoidal swing mechanism capable of simulating sea wave operations to test and control the performance of fin stabilizers. [0002] Background technique [0003] In an open ocean environment, when a ship is sailing or operating at sea, due to the influence of waves, sea wind and currents, the ship will inevitably produce swaying motions. The severe swaying not only affects the navigation of the ship, but also increases the risk of capsizing. Moreover, it will affect the equipment on board, affect the accuracy of the equipment, and also bring unstable factors to the goods and personnel on board. Therefore, for the navigation safety of the ship and the improvement of the comfort during navigation, it is urgent to reduce the vibration of the ship, and the fin stabilizer, which is one of the anti-rolling devices, was born. Fin stabilizer is ...
