[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] Specifically, two starting motor holes 6 are set up in the surface of front side shell 2 in symmetrical mode.
[0025] As Figures 1 to 4 shown, the outer surface of rear side shell 1 and front side shell 2 is coated with a layer of anticorrosive coating.
[0026] Further, the connecting surface of front side shell 2 and the rear side shell 1 is provided with sealing washer to prevent dust and liquid from entering the inside.
[0027] As Figures 1 to 4 shown, the diameter of PTO hole 4 is greater than the diameter of starting motor hole 6.
[0028] It is worth emphasizing that rear side shell 1 and front side shell 2 are connected together by bolt fixing mode.
[0029] The structure such as (electric motor) is prior art, and will not be described repeatedly; meanwhile, the utility model also includes power supply, controller and switch and the like, which are not the main technical points of the patent, and will not be described repeatedly. The wiring diagram of the motor in the utility model belongs to the common knowledge in the field, and its working principle is a known technology, and the model is selected according to actual use, so the control mode and wiring arrangement of the motor will not be explained in detail.
[0030] Working principle and flow: firstly, the gear is installed in the gear installation cavity 3, and the gear is ensured to be installed stably and to be correctly engaged with the engine and other transmission components, so that the power transmission is smooth, and the starting motor is installed on the two motor mounting seats if the double-motor working mode is needed. The starting motor is connected with the flywheel in the flywheel cavity 7 in the flywheel shell through the starting motor hole 6, and power is provided for the engine start, and the corresponding power output device is installed at the PTO hole 4, and the multifunctionality of the engine is increased according to actual needs;
[0031] When larger starting power is needed, for example, in cold environment, high load working condition or the case that the engine itself has larger resistance, the two starting motors are simultaneously connected with the power supply. The two motors simultaneously output torque, and drive the flywheel to rotate at high speed through the connection with the flywheel, and then drive the engine crankshaft to rotate, so that the engine is started quickly. This double-motor simultaneous working mode can provide larger starting torque, and ensures that the engine can be started smoothly under adverse conditions;
[0032] Under normal working condition, or when the requirement for starting power is not high, only one starting motor can be started. The motor outputs torque to drive the flywheel and the engine crankshaft to rotate, so that the engine is started. The other motor which is not started serves as a backup, and when the motor which is working fails, the backup motor can be started quickly, so that the engine can still be started normally, and the reliability of the engine start is improved;
[0033] After the engine is started, power is transmitted through the gear in the gear installation cavity 3 to drive other related components to work, at this time, the power output device installed at the PTO hole 4 starts to work, and part of the power of the engine is transmitted to the device through the PTO hole 4, so that additional functions are realized.
