[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Embodiment 1
[0025] See also Figures 1 to 5 , the utility model provides a technical solution: a flywheel housing, comprising: a housing 1, a bolt hole 2 is opened on the side of the housing 1;
[0026] The protective component 3 is arranged inside the bolt hole 2, and the bolt hole 2 is shielded and protected by the protective component 3, so that dust is prevented from entering the inside of the housing 1 through the bolt hole 2 due to the bolt hole 2 being exposed when the bolt hole 2 is not needed;
[0027] The oil passing component 4 is arranged on the surface of the protection component 3, and the oil passing component 4 assists the addition of lubricating oil and guides the lubricating oil into the interior of the housing 1;
[0028] The fixing component 5 is arranged on the surface of the shell 1. The end face of the oil-passing component 4 is fixed by the fixing component 5 to realize the installation and disassembly of the end face of the oil-passing component 4. The unused bolt holes 2 are shielded and protected by the protection component 3 to prevent dust from entering the inside of the shell 1 and to prevent the lubricating oil from flowing out of the shell 1. The addition of the lubricating oil is assisted by the oil-passing component 4 to facilitate the lubricating oil to drip into the accessories inside the shell 1.
[0029] The protection component 3 includes a protection plug 31 inserted into the bolt hole 2, and a support plate 32 is fixed to the end of the protection plug 31 away from the shell 1. The protection plug 31 is inserted into the bolt hole 2. When the bolt hole 2 is not in use, the bolt hole 2 is shielded and protected to prevent dust from entering the shell 1 through the bolt hole 2. At the same time, the lubricating oil inside the shell 1 is prevented from flowing out through the bolt hole 2.
[0030] A rubber clip 33 is glued to the outer wall of the protective plug 31, and a reinforcing rib 34 is glued to the side of the rubber clip 33 far from the protective plug 31. The side of the rubber clip 33 far from the support plate 32 is set to an arc shape. When the protective plug 31 is installed, the protective plug 31 is moved toward the direction close to the bolt hole 2, and the rubber clip 33 is squeezed by the bolt hole 2 to elastically deform. Then the rubber clip 33 passes through the bolt hole 2, and the protective plug 31 is inserted into the inside of the bolt hole 2. The end face of the rubber clip 33 is attached to the inner wall of the shell 1, and the reinforcing rib 34 supports the attachment of the rubber clip 33, so that the attachment of the rubber clip 33 to the inner wall of the shell 1 is more stable, thereby indirectly making the insertion of the protective plug 31 more stable.
[0031] The oil passing component 4 includes an oil injection hole 41 opened inside the protective plug 31, an oil delivery pipe 42 is fixed on the surface of the support plate 32, and one end of the oil delivery pipe 42 away from the support plate 32 is fixed on the surface of the guide cover 43. Through the above design, when it is necessary to add lubricating oil, take out the guide cover 43, dock the lubricating oil bottle with the guide cover 43, and the guide cover 43 guides the lubricating oil so that the lubricating oil enters the interior of the oil delivery pipe 42. Subsequently, the lubricating oil enters the interior of the oil injection hole 41 through the oil delivery pipe 42, and is sprayed out through the oil injection hole 41 to contact the accessories inside the shell 1, thereby achieving the effect of assisting the addition of lubricating oil, making the addition of lubricating oil more convenient.
[0032] A connecting ring 44 is fixed to the end face of the guide cover 43, and an opening 45 is formed on the inner wall of the connecting ring 44. The opening 45 is designed to block the lubricating oil on the inner wall of the guide cover 43 to prevent the residual lubricating oil inside the guide cover 43 from flowing back due to the tilted placement.
[0033] Embodiment 2
[0034] See also Figure 6 The fixing assembly 5 includes a fixing plate 51 fixed to the surface of the shell 1, and a limiting ring 1 52 is fixed on the side of the fixing plate 51 close to the guide cover 43, and a fixing ring 53 is fixed on the outer wall of the limiting ring 1 52, and a limiting ring 2 54 is fixed on the surface of the fixing ring 53, and a rubber snap ring 2 55 is glued to the inner wall of the limiting ring 2 54 away from the shell 1. When the guide cover 43 needs to be installed, the guide cover 43 is pushed toward the fixing plate 51. The rubber snap ring 2 55 is elastically deformed due to the extrusion of the guide cover 43, and the guide cover 43 is continuously pushed until the connecting ring 44 is engaged between the limiting ring 2 54 and the limiting ring 1 52, and the end of the rubber snap ring 2 55 away from the limiting ring 2 54 is attached to the surface of the guide cover 43, so as to realize the limiting fixation of the guide cover 43, so that the placement of the guide cover 43 is more stable.
