Abstract
The utility model discloses a gear oil pump which has simple structure, small volume and low failure rate. The gear oil pump comprises a driving gear and a driven gear that are arranged in a main pump body by a driving gear shaft and a driven gear shaft respectively; a sealing rubber layer is arranged between the main pump body and a pump cover; and two opposite end surfaces at the tooth parts of the driving gear and the driven gear have a clearances of 0.01 to 0.02mm between the corresponding end surfaces of the main pump body and the pump cover.
Description
Technical field:
The utility model relates to the gear oil pump that a kind of speed change that is used for engineering machinery is used.
Background technique:
The gearbox that present loader master joins is that the gear pumps that are used for hydraulic pressure commutation fuel feeding that two gearboxes that advance to move back the two hydrotransmitters of band are equipped with are a split type low pressure gear pump, this kind gear pump structure is simple, low cost of manufacture, but rate of fault height, phenomenon of the failure mainly show as junction plane easy oil leakage, pump to be let out in using after a period of time big, fragile.
The model utility content:
The purpose of this utility model is the deficiency that exists at prior art, and a kind of gear oil pump is provided, and this gear oil pump is simple in structure, volume is little, high working efficiency, rate of fault are low.
The technical solution of the utility model comprises the pump housing, outside framework oil seal, is located in driving gear and driven gear in the described pump housing by driving gear shaft and driven gear respectively, and the described pump housing comprises that main pump body and a pump cover that is connected in described main pump body constitute.
Be provided with a sealant layer between described main pump body and the pump cover, described outside framework oil seal is located in the main pump body.
The end face of the tooth portion of described driving gear and driven gear is provided with a spacing respectively and between the corresponding end face of the corresponding end face of main pump body and pump cover.
The end face of the tooth portion of described driving gear and driven gear respectively and the spacing between the corresponding end face of main pump body and pump cover be 0.01-0.02mm.
The utility model gear oil pump is simple in structure, volume is little, high working efficiency, low, the long service life of rate of fault.
Description of drawings
Figure is the utility model gear oil pump structural representation.
Embodiment
Now also the utility model is described in further detail in conjunction with the accompanying drawings by embodiment.As shown in the figure, the pump housing of gear pump is for being made of a main pump body 1 and a pump cover 8 that is connected in main pump body 1.Driving gear 51, driven gear 52 are located in main pump body 1 chamber by corresponding bearing 3 by driving gear shaft 53 and driven gear shaft 54 respectively, and outside framework oil seal is connected between main pump body 1 and the driving gear shaft in main pump body 1.Main pump body 1 interconnects by 7 sealings of aerobic sealing glue-line with pump cover 8.
The opposite end end face 5a of the tooth portion of driving gear 51 and driven gear 52 and 5b respectively and be provided with the spacing of 0.01-0.02mm between the end face 6 of the corresponding site of the end face 4 of the corresponding site of main pump body 1 and pump cover 8 can avoid the friction scraping phenomenon of the corresponding site of the end face of driving gear 51 and driven gear 52 and main pump body 1 and pump cover 8 like this.
