Specific embodiment
The utility model is illustrated with reference to the accompanying drawing.
As shown in Figs 1-4, the utility model includes front axle pressure cap 1 and rear axle pressure cap 2,1 He of front axle pressure cap
Rear axle pressure cap 2 is separately fixed at the both ends of bearing housing 3, and the front axle pressure cap 1 and rear axle pressure cap 2 are set as with boss
Annulus, the front axle pressure cap 1 are oiliness bearing gland, are equipped with mounting groove one and mounting groove two, institute in the front axle pressure cap 1
It states to be adapted to respectively in mounting groove one and mounting groove two and outside framework oil seal 1 and outside framework oil seal 2 12, the outside framework oil seal one is installed
11 and the sealing surface of outside framework oil seal 2 12 be oppositely arranged, the outside framework oil seal 1, outside framework oil seal 2 12 and pump shaft 4 constitute oil storage
Room 1, the front axle pressure cap 1 are equipped with the oil filler 1 of connection oil storage room 1.Oil filler connection external environment is opened
The plug being connected through a screw thread with oil filler is set at mouthful, butter is added from oil filler 1, makes butter full of oil storage room 1, protects
The sealing surface of card outside framework oil seal 1 and outside framework oil seal 2 12 has oil always, guarantees that oil sealing will not be damaged and be failed because of oil starvation.
The rear axle pressure cap 2 is oiliness bearing gland, is equipped with mounting groove three and mounting groove in the rear axle pressure cap 2
Four, adaptation is equipped with outside framework oil seal 3 21 and outside framework oil seal 4 22, the skeleton respectively in the mounting groove three and mounting groove four
The sealing surface of oil sealing 3 21 and outside framework oil seal 4 22 is oppositely arranged, 4 structure of the outside framework oil seal 3 21, outside framework oil seal 4 22 and pump shaft
At oil storage room 2 23, the rear axle pressure cap 2 is equipped with the oil filler 2 24 of connection oil storage room 2 23.Equally, from oil filler two
24 are added butter, make butter full of oil storage room 2 23, guarantee that the sealing surface of outside framework oil seal 3 21 and outside framework oil seal 4 22 has always
Oil guarantees that oil sealing will not be damaged and be failed because of oil starvation.In this way, just extending the use of front axle pressure cap 1 and rear axle pressure cap 2
Service life, to extend the service life of pump.
The top of the inner wall in the non-skeleton oil sealing sealing face of the oil storage room 1 is symmetrically arranged with perforation (i.e. oil storage tank one
Side opening with the sealing surface of outside framework oil seal one and outside framework oil seal two close contact) one 15(oil storage tank one of oil storage tank symmetrically set
Set, every side have one or more than one), the lowermost end of the oil storage tank 1 is lower than one 15 lower openings position of oil storage tank.
After oil filler addition oil storage room 1, in the use process of pump, the pump shaft 4 that butter can be rotated gradually uses up butter, disappears
After consumption a part, some places will be without oil, especially oil storage room top, therefore sets oil storage tank one in oil storage room upper inside wall
15, after oiling, oil storage tank 1 also can be full of oil, and during oil is gradually consumed, the oil of oil storage trench bottom will not be disappeared
Consumption guarantees that oil is arranged always at top, to guarantee that the contact surface of outside framework oil seal and oil storage tank has oil always, to guarantee estimation oil sealing
Sealing surface will not oil starvation.
The top of the inner wall in the non-skeleton oil sealing sealing face of the oil storage room 2 23 is symmetrically arranged with the oil storage tank two of perforation, institute
The lowermost end of oil storage tank two is stated lower than two lower openings position of oil storage tank.
As illustrated in figures 4-5, the inner wall of the oil storage tank 1 is equipped with elastic rubber inner ring 151, in the elastic rubber
The bottom (middle part) of circle 151 is equipped with cavity, and air bag 152 is equipped in the cavity, and the air bag connects air inlet pipe, the air inlet
One end of pipe is connected on air bag, and the other end is connected on the air blower being located at outside pump.It is empty without gas in air bag when refueling
Elastic rubber inner ring wall above chamber is recessed, i.e., there are oil storage spaces, are pumping after a period of use, is filled with into air bag a small amount of
Gas, make to slightly lift among the bottom of oil storage tank 1, so that the oil in lower concave space is lifted two to oil storage tank one
Side opening stream flow to the outside framework oil seal of two sides；After continuing to use pump a period of time, rethinks and be filled with a small amount of gas in air bag, so that
Oil is diffused out again to two effluents.It can be beforehand with experiment for pump, observing its operation, how long oil is lost to oil storage tank or less
(can protrude into miniature webcam by oil filler), how long the oil in oil storage tank is not contacted with outside framework oil seal for operation, according to reality
The time tested formulates the inflationtime in pump normal use process, to guarantee that the top of outside framework oil seal is contacted with oil always, wait store up
After oil consumption in oil groove is complete, then from oil filler oil is rejoined, to achieve the purpose that saving.
