By setting the lubrication component 2, when lubrication is required between the rotating shaft 4 and the brushless generator body 1, the mounting box 22 in the mounting hole 21 is filled with lubricating oil, and then the lubrication roller 23 is brought into contact with the rotating shaft 4, and the rotating shaft 4 is rotated to rotate the lubrication roller 23, thereby rotating the lubricating oil and rotating it out, so as to evenly apply it to the rotating shaft 4, thereby achieving the effect of convenient lubrication of the rotating shaft 4 and comprehensive lubrication between the rotating shaft 4 and the brushless generator body 1 as much as possible. The top of the inner wall of the mounting hole 21 is fixedly connected to a first spring 24, and the other end of the first spring 24 is fixed to the mounting box 22.

The limit block 26 is reset by setting the second spring 28.

[0031] Reference Figure 3As shown, in this embodiment: the refueling assembly 3 includes an oil filling cylinder 31 and an oil barrel 35 fixedly connected to the upper end of the brushless generator body 1, and an oil pipe 34 is fixedly connected between the oil filling cylinder 31 and the mounting box 22, and the oil pipe 34 runs through the brushless generator body 1. When it is necessary to refuel the mounting box 22, the lubricating oil in the oil filling cylinder 31 is squeezed into the mounting box 22 through the oil pipe 34 through the pushing mechanism. The inner wall of the oil filling cylinder 31 is provided with a piston 32, and the upper end of the piston 32 is fixedly connected with a push rod 33, which runs through the oil filling cylinder 31.

[0032] Working principle:

[0033] When the brushless generator body 1 is in use, the shaft 4 is rotated to make the rotor rotate. Since the excitation winding of the main generator is in the rotor and the armature winding is in the stator, the armature winding of the exciter is in the rotor and the excitation winding is in the stator, the excitation winding of the exciter on the stator is provided with excitation, and the armature winding of the rotor will generate alternating current. After passing through the rotating rectifier, the rotor supplies power to the excitation winding of the main generator on the rotor, so that the armature winding of the main generator on the stator induces the required alternating current. When the shaft 4 and the brushless generator are required to be rotated, the armature winding of the exciter is in the rotor and the excitation winding is in the stator. When lubricating the machine body 1, fill the installation box 22 in the installation hole 21 with lubricating oil, then let the lubricating roller 23 contact the rotating shaft 4, rotate the rotating shaft 4, so that the lubricating roller 23 rotates, thereby rotating and bringing out the lubricating oil, and evenly applying it to the rotating shaft 4, thereby achieving the effect of convenient lubrication of the rotating shaft 4 and comprehensive lubrication between the rotating shaft 4 and the brushless generator body 1 as much as possible. By setting the first spring 24, the installation box 22 is squeezed, so that the lubricating roller 23 and the rotating shaft 4 are fully in contact, and no lubrication is required. When the lubricating roller 23 and the rotating shaft 4 are not in contact, the limiting rod 29 is lifted upwards, so that the mounting box 22 moves, and the lubricating roller 23 and the rotating shaft 4 are not in contact. Then the limiting rod 29 is moved to the left so that it is mounted on the fixing block 27, thereby limiting the mounting box 22. By setting the second spring 28, the limiting block 26 is reset. When it is necessary to refuel the mounting box 22, the push rod 33 is pushed downwards, so that the piston 32 moves, so that the lubricating oil in the oiling cylinder 31 is squeezed into the mounting box 22 through the oil pipe 34. A third spring 38 is provided to reset the piston 32. When the lubricating oil in the oil filling cylinder 31 needs to be replenished, when the piston 32 resets upward, under the action of the first one-way valve 37, the lubricating oil in the oil barrel 35 flows to the oil filling cylinder 31 through the connecting pipe 36, thereby replenishing the oil. By providing the first one-way valve 37, the lubricating oil in the oil barrel 35 can flow into the oil filling cylinder 31, but not vice versa. By providing the second one-way valve, the lubricating oil in the mounting box 22 cannot flow into the oil filling cylinder 31, but vice versa.
