Abstract
Description
Technical Field
[0001] This utility model belongs to the field of housing technology, and specifically relates to a waterproof housing for a starter motor. Background Technology
[0002] Currently, Chinese utility model patent CN215300322U discloses a small starter housing. Although the housing is made of aluminum, which effectively improves heat dissipation and conductivity, other problems still exist during use. For example, it is inconvenient to add lubricating oil. In order to improve the transmission effect of the internal gears and screws, lubricating oil needs to be added regularly. When adding lubricating oil, the housing needs to be removed from the equipment before the oil can be added from the front opening, which is time-consuming and laborious. Moreover, the impact protection of the rear end is poor. When the rear end of the housing is hit by an external object, it will dent or even deform after being subjected to force, which will cause compression and damage to the internal components and increase the maintenance cost of the product. Utility Model Content
[0003] The purpose of this invention is to provide a waterproof housing for a starter motor, which has the advantages of facilitating the addition of lubricating oil and improving the protection effect of the rear end.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a waterproof housing for a starter motor, including a front cylinder, a rear cylinder bolted to the front of the front cylinder, a fixing frame mounted on the surface of the rear cylinder, an oil inlet on the surface of the front cylinder located within the fixing frame, a cover plate bolted to the surface of the fixing frame, an integrally formed mounting groove at the other end of the rear cylinder, a fixing plate bolted inside the mounting groove, a protective plate provided on the front of the fixing plate, a buffer spring bolted between the front of the fixing plate and the protective plate by a spring fixing piece, and a damper installed between the front of the fixing plate and the protective plate.
[0005] The above technical solution facilitates the addition of lubricating oil, is simple and convenient to operate, reduces the burden on personnel for overall disassembly and calibration, offers good flexibility, improves the protection effect of the rear end, reduces the damage and impact of impact on the product, extends the product's service life, and is highly practical.
[0006] The present invention is further provided that a waterproof sealing ring is adhered to one side of the front cylinder and the rear cylinder on opposite sides.
[0007] By adopting the above technical solution, the waterproof sealing ring can improve the sealing and waterproofing effect between the front and rear cylinders after installation.
[0008] The present invention is further configured such that an oil baffle is installed inside the cover plate, and the diameter of the oil baffle is larger than the inner diameter of the oil inlet.
[0009] The above technical solution is adopted: by setting the oil baffle, the lubricating oil injected into the front cylinder from the oil inlet can be blocked, preventing the lubricating oil from flowing back into the fixed frame.
[0010] The present invention is further provided that mounting holes are provided on both sides of the mounting end of the front cylinder surface.
[0011] The above technical solution allows for easy fixing of the front cylinder by screws through the mounting holes.
[0012] The present invention is further configured such that the buffer spring is made of carbon spring steel.
[0013] Using the above technical solution, the buffer spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.
[0014] The present invention is further provided that the surfaces of the front cylinder and the rear cylinder are coated with anti-corrosion coating.
[0015] By adopting the above technical solution, the anti-corrosion and moisture-proof effects of the front and rear cylinder surfaces can be improved through the application of anti-corrosion coatings.
[0016] In summary, this utility model has the following beneficial effects:
[0017] 1. First, use screws to remove the cover plate from the fixed frame. After removing the fixed frame, the oil baffle plug will be taken out along with it. Then, use a syringe to push the lubricating oil from the oil inlet into the front cylinder. After the lubricating oil is injected, lift the cover plate again. After lifting the cover plate, insert the oil baffle plug into the fixed frame to seal the oil inlet. Finally, tighten the cover plate with screws. This makes it easy to add lubricating oil. The operation is simple and convenient, reducing the burden of disassembly, assembly and calibration for personnel. It is also very flexible.
[0018] 2. When the rear end of the cylinder is impacted, it will first collide with the protective plate. After being subjected to force, the protective plate will move backward. When the protective plate moves backward, it will press against the buffer spring and damper in the mounting groove. Since the buffer spring is elastic, when the buffer spring and damper are compressed and contracted, they will absorb and offset the force energy, which can improve the protection effect of the rear end, reduce the damage and impact of the impact on the product, extend the service life of the product, and have high practicality.

The cover plate 5 is removed from the fixing frame 3 using screws, which also removes the oil baffle plug 11. Lubricating oil is then injected into the front cylinder 1 through the oil inlet 4 using a syringe. After the lubricating oil is injected, the cover plate 5 is removed again, and the oil baffle plug 11 is inserted into the fixing frame 3 to seal the oil inlet 4. Finally, the cover plate 5 is tightened with screws.
