Problems solved by technology
[0004] However, since the gear type oil pump only has an oil inlet chamber and an oil outlet chamber, the flow rate and pressure of the output lubricating oil are fixed under the condition that the rotating speed of the driving gear and the driven gear is constant, and the corresponding parts can only be controlled. oil supply
When it is necessary to supply oil to other components, multiple gear oil pumps of the same type or different types are required to cooperate to complete the oil supply work. Since a single gear oil pump has a certain weight and volume, setting multiple gear oil pumps The oil pump will increase the weight of the car or other mechanical equipment, and also increase the installation space of the oil pump

The invention discloses a gear type engine oil pump, comprising a pump body and gear banks, wherein the pump body is provided with at least two working cavities; each working cavity is provided with a first oil cavity and a second oil cavity; the pump body is provided with first oil ports and second oil ports; the first oil ports are communicated with the first oil cavities of the working cavities in a one-to-one correspondence way; the second oil ports are communicated with the second oil cavities of the working cavities in the one-to-one correspondence way; each working cavity is provided with one gear bank; each gear bank comprises a driving gear and a driven gear; the driving gears and the driven gears are engaged and connected in a transmission way; the gear banks are all connected with a drive device. Meanwhile, the invention also discloses a lubricating oil system, comprising a lubricating oil tank, the drive device and the preceding gear type engine oil pump, wherein the lubricating oil tank is communicated with the first oil ports in the one-to-one correspondence way; the second oil ports are used for being communicated with lubricating oil pipelines in the one-to-one correspondence way. By the adoption of the lubricating oil system and the gear type engine oil pump thereof provided by the invention, oil supply to multiple pieces of equipment can be met, and the installation space of an engine oil pump is simultaneously decreased.
Description
technical field [0001] The invention relates to the technical field of oil pumps, in particular to a lubricating oil system and a gear type oil pump thereof. Background technique [0002] In automobiles and other mechanical equipment, lubricating oil is an essential oil, and an oil pump is usually used to deliver the lubricating oil. The function of the oil pump is to increase the oil pressure of the lubricating oil, forcing the lubricating oil to be sent to each component, and lubricating each component. [0003] A traditional gear oil pump mainly includes a pump body, a pump cover, a driving gear, a driven gear, and a driving shaft. The driving shaft is connected with the driving device. When the driving shaft rotates, the driving gear drives the driven gear to rotate. When the teeth of the driving gear and the teeth of the driven gear are from meshing to disengaging, a partial Vacuum sucks the lubricating oil into the oil inlet chamber. During the rotation of the gear, ...
