Abstract
A high oil-absorption performance lubricated gear pump increases a gear ring sleeved with the external edge of the front pump on the base of the normal gear pump structure. The gear ring is provided with an oil-mixing vane and an oil feeding impeller whose external side is provided with a funnel-type oil guide shell; the gear ring is transmitted by a shaft gear of the driven gear end through a middle gear. The mixing of the oil-mixing vane is implemented to reduce the viscosity of the grease and to increase the fluidity of the grease, and then the grease is guided into the oil inlet of the gear pump by the match function between the oil feeding impeller and the guide shell. The gear pump has good oil absorption performance in viscous grease, and is especially suitable for the concentrated lubricating device in the vehicle and machinery which need the grease with high viscosity.
Description
(1) technical field
The utility model relates to the grease lubrication technical field, relates in particular to the lubricating gearing pump with high oil-absorbing performance in the grease centralized lubrication device on a kind of vehicle and the machinery.
(2) background technique
More and more vehicle and machinery adopt grease centralized lubrication device, and this device adopts the common full depth tooth wheel pump of mechanical industry as supplying the fatty oil pump mostly.Owing to be subjected to the restriction of full depth tooth wheel pump suction capacity, lubricating fitting can only be with the low grease of stickiness in this class set, though satisfied pump-conveying property, but partly sacrificed the good lubrication performance of grease, be unfavorable for and be easy to very much leakage that fuel consumption is big, kinematic pair is easy to the grease contamination environment that weares and teares and miss lubricated.Using stickiness higher or under service conditions such as high height above sea level, low temperature, tending to occur for fat is bad phenomenon such as not enough, grease emulsifying and extraordinary noise.To the limitations affect of grease stickiness further the applying of lubricating fitting in this class set because it and be not suitable for the more use occasion of high viscosity grease of requirement.Therefore, press for the lubricating gear pump into a kind of high oil-absorbing energy of grease centralized lubrication device development, the performance that is beneficial to it is normally brought into play, and improves its adaptive capacity, makes it can obtain popularizing in an all-round way application on various vehicles and machinery.
(3) summary of the invention
The technical problem that the utility model mainly solves: take structural measure, improve the oil absorption of gear pump, a kind of lubricating gearing pump with high oil-absorbing performance that is used for vehicle and machinery centralized lubrication device is provided.
The technical solution adopted in the utility model: a kind of external gear pump, by driving gear, driven gear, front pump cover, rear pump cover, the pump housing, intermediate gear, gear ring, stir oily blade, oil transportation impeller, Oil Guide shell and some clamping bolts are formed.Wherein wheel pump is nibbled in the outer gearing of driving gear, driven gear, front pump cover, rear pump cover and a conventional structure of pump housing formation.The utility model is taked following further technical measures on this basis, termination with an end of driven gear shaft, be processed into a shaftgear, outer rim at the gear pump front pump cover, put a gear ring that forms friction pair mutually, the gear ring outside is equipped with the oil transportation impeller and stirs oily blade, and then there is a funnel shaped Oil Guide shell in the impeller outside.Take after this structure, when gear pump is worked, driven gear will be by the next power of driving gear transmission, be passed to gear ring by intermediate gear, gear ring rotates around front pump cover with the rotating speed much lower than driving gear, and that installs on the gear ring stirs the grease that oily blade stirs the gear pump top, make grease between can overcoming mutually cohesive force and flowed, and the local stickiness that reduces, the oil transportation impeller then forms a simple oil delivering device with funnel shape guiding shell.When gear pump was worked, grease can flow to the filler opening of gear pump continuously along the inwall of Oil Guide shell under the double action of stirring oily blade and oil transportation impeller, was constantly replenished to guarantee filler opening place grease.Filler opening is opened on the end face of gear pump rear pump cover.
The utility model stirs the local grease stickiness that reduces of oily blade owing to having adopted, and has improved the mobile performance of grease, adopts the oil transportation impeller again grease to be transferred to filler opening simultaneously, has effectively improved the oil absorption of gear pump.Adopt the lubricating gear pump of this high oil-absorbing energy, can make grease centralized lubrication device can use the grease of high viscosity as working medium.
Therefore, the utility model can improve the adaptability of grease centralized lubrication device to service conditions such as different greases, different weather and Different Altitude, and the performance that helps grease centralized lubrication device is brought into play and promoted the use of.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
As shown in Figure 1, driving gear 1, driven gear 2, front pump cover 3, the pump housing 4, rear pump cover 5, the external gear pump of a conventional structure of formation.Be processed with shaftgear 11 at the driven gear axle head, be with an intermediate gear 6 on construction bolt 12, construction bolt and intermediate gear axis hole are for being slidingly matched.Front pump cover outer rim 13 is a cylindrical structural, the outside is with a gear ring 7, gear ring 7 tops are equipped with 2～4 and uniform stir oily blade 9, gear ring 7 outer rims then are equipped with an oil transportation impeller 8, oil transportation impeller 8 outsides are a funnel shaped Oil Guide shell 10, Oil Guide shell 10 is fixed on the lower plane 14 of front pump cover 3, and filler opening 15 is opened on the end face of gear pump rear pump cover.
