Description

Split type gearbox Cross Reference to Related Applications The present application is a non-provisional application claiming priority from U.S. provisional patent application No. 63/535,514 entitled "Split Gearbox (split gearbox)" filed 8/30 of 2023, which is incorporated herein by reference. Background This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these descriptions should be read in light of the foregoing, and are not admitted to be prior art. Technological advances in the automotive industry have led to an increase in the number of hybrid gas-electric vehicles used. Hybrid vehicles are capable of reducing fuel consumption and its associated emissions. In contrast, propulsion systems for aircraft generally continue to use conventional gas turbine engines. Hybrid technology is beginning to be increasingly accepted in the marine industry as a method of reducing fuel consumption and emissions associated with performing industrial marine tasks of ships. The suitability of a ship for use with hybrid technology depends primarily on its operating cycle and operating characteristics (operational profile). For example, an application that is generally well suited for hybrid propulsion is one in which the marine design is based on a wide range of power requirements, but it is expected that most of the time will be in a low power operating state. Vessels that may fit this feature include patrol vessels, tugs, work vessels, near sea supply vessels (OSV), platform Supply Vessels (PSV), lead vessels, research vessels, fishing vessels, navigation mark laying vessels, icebreaker vessels, naval vessels, and many other types. When considering newly constructed vessels, it is believed that the application of hybrid technology is not difficult to integrate into the vessel design, and that the additional capital expenditure can be offset by the expected future savings (e.g., fuel costs). Of the vessels that will operate for the next 30 years, most vessels have been built, and these existing vessels are equipped with conventional power systems, except for a very small number of early adopters. Drawings These and other features, aspects, and advantages of the present disclosure will become better understood when the following detailed description is read with reference to the accompanying drawings in which like characters represent like parts throughout the drawings, wherein: FIG. 1 shows a cross-sectional side view of a drive system according to an embodiment, and Fig. 2 shows a flow chart describing the installation of the drive system of fig. 1, according to an embodiment. Detailed Description One or more specific embodiments of the present disclosure will be described below. In the interest of brevity of description of these embodiments, all of the features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure. When introducing elements of various embodiments of the present disclosure, the articles "a," "an," "the," and "said" are intended to mean that there are one or more of the elements. The terms "comprising," "including," and "having" are intended to be inclusive and mean that there may be additional elements other than the listed elements. Any examples of operating parameters and/or environmental conditions do not preclude other parameters/conditions of the disclosed embodiments. There are a number of opportunities for hybrid powerization for existing vessels whose operating characteristics support hybrid designs. There are only a few cases worldwide where existing vessels are successfully converted into hybrid systems. This is partly due to the challenges presented by conversion with any vessel. Furthermore, the current integration of electric motors into conventional propulsion mechanical drive systems to retrofit propulsion shafting is a very damaging and costly task. The loss of revenue and the cost of modification associated with ships often offset the commercial viability of hybrid conversion. Conventional electric motor designs limit the ability of
