Embodiment Construction
[0016] The accompanying drawing is a schematic structural diagram of the present invention, as shown in the figure: the low-noise gear oil pump of this embodiment includes a pump cylinder 3 and two gears 1 that are engaged with each other in the pump cylinder 3, and the tooth surfaces of the two gears 1 are Secure the cover elastic2.
[0017] In this embodiment, the material of the elastic layer 2 is filled polytetrafluoroethylene; it has good oil resistance, wear resistance, and self-lubricating performance, and is suitable for a motor vehicle lubricating oil pump.
[0018] In this embodiment, metal powder is added to the filled polytetrafluoroethylene to further increase the wear resistance and improve the service life of the oil pump.
[0019] Of course, the material of the elastic layer 2 is a resin-based elastic oil-resistant and wear-resistant material; it has high strength and improves the ability of the elastic layer to resist impact loads, which can also achieve the p...
