DETAILED DESCRIPTION
[0020] In the description of the present invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] The following is combined with Figure 1-6 The utility model is further described.
[0023] In order to solve the problems existing in the background technology, the present application proposes the following technical solutions: a front axle of a generator with an oil stain cleaning effect, comprising an outer shell 2 and a shaft 1, the shaft 1 passes through the outer shell 2 and is rotatably connected to the outer shell 2; a reciprocating screw 3 and a guide rod 5 are provided on the outside of the outer shell 2, a reciprocating nut 4 is threadedly connected to the reciprocating screw 3, the guide rod 5 passes through the reciprocating nut 4, a cleaning assembly is provided under the reciprocating nut 4, and a driving assembly for driving the reciprocating screw 3 is provided in the outer shell 2.
[0024] In the specific technical solution, the cleaning component includes a fixing ring 6 fixedly connected to the bottom of the reciprocating nut 4 and a supporting ring 7 arranged on both sides of the fixing ring 6. Cleaning cotton is fixedly connected to the outside of the supporting ring 7. The supporting ring 7 is an arc-shaped structure. The cleaning cotton is detachably fixedly connected to the outside of the supporting ring 7. The cleaning cotton can be cotton cloth, and the cleaning cotton can be bonded to the outside of the supporting ring 7 for easy disassembly and replacement.
[0025] In a further design, a spring 9 is connected between the fixed ring 6 and the support ring 7, and an electromagnet 8 is fixedly connected to the fixed ring 6 and the support ring 7. The fixed ring 6 and the support ring 7 are both sleeved on the outside of the shaft 1. During subsequent cleaning, the two electromagnets 8 are energized. Since the two electromagnets 8 repel each other with the same poles, the support ring 7 can drive the cleaning cotton to contact the outside of the shaft 1 under the action of the repulsive force.
[0026] Among them, a sliding mouth 15 is also provided on the outside of the shell 2, and one end of the reciprocating screw rod 3 extends into the shell 2 through the sliding mouth 15. The driving assembly includes a second gear 17 fixedly connected to the outside of the shaft rod 1 and a first gear 16 fixedly connected to the end of the reciprocating screw rod 3. The first gear 16 and the second gear 17 are meshed with each other. The diameter of the first gear 16 is smaller than the diameter of the second gear 17. Therefore, when the shaft rod 1 rotates, the second gear 17 drives the first gear 16 to rotate, so it can drive the reciprocating screw rod 3 to rotate, so that the reciprocating nut 4 can move back and forth.
[0027] In further refinement, a mounting frame 10 is also provided in the outer shell 2, and the reciprocating screw 3 is rotatably connected to the mounting frame 10. A connecting plate 13 is fixedly connected to the outside of the mounting frame 10, and a through frame 14 is fixedly connected to the outside of the connecting plate 13. One end of the through frame 14 passes through the slide 15 and is fixedly connected to the guide rod 5. The reciprocating screw 3 is rotatably connected to the through frame 14, and an electric push rod 18 is fixedly connected in the outer shell 2. The piston rod of the electric push rod 18 is fixedly connected to the mounting frame 10. The electric push rod 18 can push the mounting frame 10 to move upward or downward, so that the position can be adjusted to achieve the engagement or disengagement of the first gear 16 and the second gear 17. In order to guide the slide rail 11, a slide rail 11 is also fixedly connected in the outer shell 2, and a slider 12 is slidably connected in the slide rail 11, and the slider 12 is fixedly connected to the mounting frame 10.
[0028] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:
[0029] The shaft 1 and the housing 2 are installed in the generator. When the generator is working, the shaft 1 is driven to rotate. The shaft 1 is meshed with the first gear 16 and the second gear 17, so it can drive the reciprocating screw 3 to rotate. The reciprocating screw 3 drives the reciprocating nut 4 to continue to reciprocate. Then, the two electromagnets 8 are energized. Since the two electromagnets 8 repel each other with the same poles, the support ring 7 can drive the cleaning cotton to contact the outside of the shaft 1 under the action of the repulsive force, so that when the reciprocating nut 4 moves, the oil stains on the outside of the shaft 1 can be cleaned by the cleaning cotton.
[0030] In addition, if the shaft 1 does not need to be cleaned, it is only necessary to cut off the power to the electromagnet 8. Therefore, under the elastic force of the spring 9, the support ring 7 will no longer be in contact with the shaft 1. In addition, the mounting frame 10 is pushed upward by the electric push rod 18 to disengage the first gear 16 and the second gear 17, so that the reciprocating screw 3 will not rotate. If it is necessary to clean it again later, it is only necessary to start the electric push rod 18 again to move it downward to engage the first gear 16 and the second gear 17.
[0031] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.
