The two new types of marine gearboxes of telescopic lateral Thruster and the Parallel Operation Twin PTO made by Nanjing High Accurate Marine Obtained the National Inventional Patent License

Recently, the marine gearboxes of telescopic lateral thruster and the parallel operation twin PTO made by Nanjing High Accurate Marine Equipment Co., Ltd. obtained the national inventional patent license. So far, Nanjing High Accurate Marine has achieved 49 patents of various kinds, among which 6 were inventional patents.

The lateral thruster is an important part to improving the marine operation performance. The telescopic lateral thrusters developed and made by Nanjing High Accurate Marine is aimed to remedy the deficiency of the traditional ones that the position of the blade centerline and hull waterline is fixed, and the blade centerline below the light load waterline is shallow, which will directly effect the propulsion performance of the thruster, especially in the condition of insufficient water depth, the traditional ones can not satisfy the hull thrust required, so that the reliable new type of marine lateral thruster came out. This type of lateral thruster can change the distance of the blade central line below the waterline through assembling the hydraulic cylinder to make up-and-down movement, so that it can avoid the underpowered condition due to the shallow waterline.

The marine gearboxes are the most important transmission parts in the marine transmission equipments. The parallel operation twin PTO marine gearboxes are the controllable pitch propeller marine gearboxes equipped with dual-host input, single main drive output and twin PTO output. So far, most of the ships are used single main drive input and single main drive output to drive the propeller. As the increasing demand of the users for energy efficiency, the ships need different power levels in different work conditions like towing, cruising or supplying. According to the requirements of customers, the gearboxes should be with auxiliary power output to generate electricity or fire fighting. The parallel operation twin PTO marine gearboxes have the features of double main drive input and each input shaft assembled with main clutch, so that it can combine or release the main clutch in different work conditions and receive different power output. The auxiliary device is with twin PTO, each is assembled with clutch so that it can combine or release the PTO clutch to make PTO output in different work conditions. The gearboxes have the features of simple structure, high reliability, small volume, energy saving and can satisfy the multifunctional market demand.

Nanjing High Accurate Marine has been insisting on the intellectual property strategy, and focusing on the protection of research results proprietary intellectual property rights. Meanwhile it has been sticking to the way of technology innovation to long lasting development. It made a completed competitive and motivation policy, encouraged scientific and technology innovation with many kinds of methods. It has formed a timely and efficient R&D organization system that complies with the requirement of the market economy, which can promote the improvement of the R&D ability of the company, and also laid a solid foundation for the Science and Technology Enterprises.
