Abstract
In the invention, on the outer edge of a front pump cover is disposed a gear ring, on which are mounted an oil-mixing blade and an oil-transporting impeller. There is a hopper oil-guide casing outside the oil-transporting impeller. The gear ring is driven by a shaft gear at driven gear end through a middle gear.
Description
(1) technical field
The present invention relates to the grease lubrication technical field, relate 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 present invention 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 used in the present invention: 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 present invention takes 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 present invention 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 present invention 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.
