Description
Technical Field
The invention relates to a ship steering engine, in particular to a ship electric steering engine adopting a gear shell output type small-tooth-difference planetary transmission mechanism.
Background
For a long time, based on the characteristic of large output of hydraulic actuators including hydraulic motors, hydraulic oil cylinders and the like, the power form of electric hydraulic pressure is selected by most ship deck machinery including ship steering engines. However, the hydraulic system has the problems of leakage, oil contamination, servo mechanism failure, low efficiency and the like.
The purely electric steering engine for the ship overcomes the problems of an electric hydraulic system; but the current products are only used on small ships. The transmission mode mainly adopts worm and gear transmission or individually adopts a transmission mode similar to a crane rotating device and in which a rotating support is driven by an electric planetary gear reducer. Due to the strength of the material, the transmission mode of the electric steering engine inevitably meets the special requirements of extremely large steering torque and low rotating speed with a large structural size.
At present, a multi-tooth transmission-based planetary cycloid speed reducer is currently concerned by individual ship electric steering engine research mechanisms, and a scheme similar to a robot RV speed reducer structure form is provided. However, the operating conditions, working environment and reliability and RV of marine electric steering engines are different. The space requirement for the RV reducer to be too compact necessarily increases the complexity of the structure and the cost of the system; meanwhile, most RV products cannot be well filled with oil to operate, and the long-term reliability requirement of marine equipment cannot be met.
Disclosure of Invention
The invention provides a ship electric steering engine adopting a gear shell output type planetary transmission mechanism with small tooth difference, aiming at the problems of large structure size, complex structure and higher cost of the existing ship electric steering engine product or scheme.
The technical scheme of the invention is as follows: an electric steering engine of ship adopting a gear shell output type small-tooth-difference planetary transmission mechanism comprises one or more than one motor and a speed reducer containing one or more than one transmission mechanism; the final transmission mechanism of the speed reducer is a small-tooth-difference planetary transmission mechanism which adopts a tooth shell to output steering torque.
The invention has the beneficial effects that: the ship electric steering engine adopting the gear shell output type small-tooth-difference planetary transmission mechanism not only can simplify the system and ensure that the whole engine obtains large transmission ratio and high transmission efficiency, but also can ensure that the whole engine is extremely light, compact and concise; meanwhile, as the moving parts in the speed reducer are in the oil-filled operating environment without leakage risk, the abrasion is greatly reduced, and the reliability is improved.
