Abstract
The utility model relates to a high-flow oil pump which consists of a pump body, a pump cover, a driving shaft, a driving gear, a transmission gear, a driven shaft and a driven gear. The pump cover is arranged on the pump body by a bolt, the driving shaft and the driving gear are in interference fit and then are arranged in a gear shaft hole of the pump body and a shaft hole of the pump cover, the transmission gear is arranged at the outer end of the driving shaft and is mainly responsible for the rotation and the oil pumping of the oil pump; and the driven shaft and the driven gear are in interference fit and then are arranged in the gear shaft hole of the pump body and the shaft hole of the pump cover. The module number of the driving gear is six, the tooth number of the driving gear is nine; and the module number of the driven gear is 6, and the tooth number of the driven gear is nine.
Description
Technical field
This practicality newly relates to the oil pump technical field, particularly a kind of big flow oil pump of using on heavy-duty engine.
Background technique
The existing a kind of and supporting motor main frame of tourism speedboat, its horsepower is 720, it is to be formed with 480 horsepower engine modifications by heavy goods vehicles, can't satisfy the lubrication technology requirement of reequiping the back high-powered engine and have now with its supporting oil pump capacity.Therefore, need a kind of novel and its supporting big flow oil pump, it is reached and supporting technical requirements and the using property data of repacking back high-powered engine.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes on the prior art, and the supporting big flow oil pump of high-powered engine after a kind of and the repacking is provided.
The technical solution of the utility model is: a kind of big flow oil pump, form by the pump housing, pump cover, driving shaft, driving gear, driving gear, driven shaft, driven gear.Pump cover is installed on the pump housing by screw, is installed in the axis hole of pump housing gear axis hole and pump cover after driving shaft and the driving gear interference fit, and the driving shaft outer end is equipped with driving gear, mainly bears the rotation and the pump oil of oil pump; Be installed in after driven shaft and the driven gear interference fit in the axis hole of the gear axis hole of the pump housing and pump cover.
The modulus of described driving gear is 6, and the number of teeth is 9 teeth.The modulus of driven gear is 6, and the number of teeth is 9 teeth.
The utility model compared with prior art has following characteristics:
The big flow oil pump compact structure that the utility model provides, component configuration are installed rationally, and the module of driving gear and driven gear is M6, and the number of teeth is 9 teeth, has increased the volume of tooth cavity oil transportation, has improved the unit time flow rate of lubricating oil.Under the driving of motor speedup, oil pump per minute rotating speed changes by 2100 brings up to per minute 3000 commentaries on classics, lubricated flow-rate ratio is original to improve 45%～50%, reach the repacking rear engine and increase the technical specifications that the needed fuel delivery of horsepower, characteristic of fuel delivery and raising are renderd a service engine lubrication, also improved Security, reliability and the working life of repacking back high-powered engine simultaneously.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
