Description
Technical field
This utility model relates to bearing grease injection frock, for Bearing inner oil addition fat.
Background technology
Hub bearing is double row angular contact bearing, and a generation, secondary hub-bearing unit exist interpolation profit during assembling
Lubricating oil fat operation, greasing operation conventionally employed Double End grease injection method, after one side greasing completes, bearing overturns, and carries out another side
Greasing, complex operation；And the sealing ring on greasing operation bearing does not press-fits, bearing is in switching process, and grease the most easily goes out
Existing spillover.
Summary of the invention
The present utility model purpose: for the defect overcoming prior art to exist, this utility model provides one to use
The greasing of bearing middle part, easy to operate, reduce and even avoid the hub bearing greasing frock that in operating process, oils and fats is revealed.
For achieving the above object, this utility model provides following technical scheme:
A kind of hub bearing greasing frock, including base, base is provided with bearing block, and bearing block is provided with confession
The step shaft part of bearing suit supporting, is provided with greasing passage in bearing block, greasing passage includes axially extended main channel,
One end, main channel is provided with the oils and fats inlet running through bearing block, and the main channel other end extends in step shaft part, Step Shaft
Section medium position is provided with radial direction through hole, and radial direction through hole the inner is led in main channel, and radial direction through hole outer end is run through outside step shaft part
Wall.
In use, hub bearing inner ring is sleeved on step shaft part realization to hub bearing greasing frock of the present utility model
Location, firm position is reliable, and the gap between the radial direction through hole external port correspondence hub bearing two lobe inner ring of greasing passage, by oil
Fat is passed through in main channel from oils and fats inlet, and oils and fats injects in hub bearing along main channel through radial direction through hole；Realize hub bearing
Suit location, sets radial direction through hole on the step shaft part for bearing inner race suit, thus realizes noting to bearing middle part
Entering oils and fats, bearing need not twice greasing of turn-over, easy to operate, and oils and fats is distributed in bearing near middle part, does not haves
The phenomenon overflowed.
Preferably, the outer circumference surface of described step shaft part is provided with at least two seals circle, and two seals circle divides vertically
It is located at the external port both sides of radial direction through hole.Under the design of this structure so that end count seal when coordinating of bearing inner race and step shaft part
Seal, it is to avoid the phenomenon of a small amount of leakage occurs during grease pumping.
Preferably, described step shaft part is circumferentially distributed some radial direction through hole.Under the design of this structure, improve greasing effect
Rate and guarantee greasing are uniform.
Preferably, described oils and fats inlet is the enlarging more than main channel.Under the design of this structure, have and be easy to oils and fats injection
Operation, the advantage of reliable operation.
Preferably, described oils and fats inlet is positioned at the bottom of bearing block, is provided with oils and fats inlet even on base
Logical port.Under the design of this structure, the oils and fats inlet of main channel is located at the bottom of bearing block, simple in construction, it is simple to add
Work.
Below in conjunction with the accompanying drawings this utility model is further described.
Accompanying drawing explanation
Fig. 1 is that this utility model specific embodiment hub bearing greasing frock uses state diagram；
Fig. 2 is this utility model specific embodiment bearing block structural representation；
Fig. 3 is part A partial enlarged view in Fig. 1.
Detailed description of the invention
As shown in Fig. 1 ~ 3, disclosed in this utility model, a kind of hub bearing greasing frock, including base 1, base 1 sets
Having bearing block 2, bearing block 2 can molded design integral with base 1, it is possible to use detachable installation, and this practicality is newly
Type preferably employs detachable installation, so convenient processing and use, and bearing block 2 is provided with the platform for bearing 8 suit supporting
Rank shaft part 21, is provided with greasing passage in bearing block 2, greasing passage includes axially extended main channel 22, main channel 22 1
End is provided with the oils and fats inlet 23 running through bearing block, and main channel 22 other end extends in step shaft part 21, step shaft part
21 medium positions are provided with radial direction through hole 24, and radial direction through hole 24 the inner is led in main channel 22, and platform is run through in radial direction through hole 24 outer end
Rank shaft part 21 outer wall, it is achieved realize oils and fats injection in the gap in the middle part of the oils and fats importing bearing inner race in main channel.And
Described step shaft part 21 is circumferentially distributed some radial direction through hole 24, usually 12-16, can adjust according to actual needs
Whole, so in the circumference of bearing inner race, multiple positions are injected simultaneously into, and improve greasing efficiency and ensure that greasing is uniform.
For ensureing that between bearing inner race and step shaft part, fitted seal is reliable, effective minimizing even stops to reveal, described
The outer circumference surface of rank shaft part 21 is provided with at least two seals circle 25, uses twice in figure, as it is shown on figure 3, two seals circle 25
It is divided into the external port both sides of radial direction through hole 24 vertically, both reaches radial direction through hole both sides sealing.Sealing ring makes bearing inner race
With step shaft part reach when coordinating reliably seal, it is to avoid the phenomenon of a small amount of leakage occurs during grease pumping.
Wherein, oils and fats inlet 23 can radially through bearing block 2, it is possible to use axially through bearing block, excellent
Choosing is designed as: described oils and fats inlet 23 is positioned at the bottom of bearing block 23, is provided with oils and fats inlet 23 even on base 1
Logical port 11.The oils and fats inlet of main channel is located at the bottom of bearing block, simple in construction, it is simple to processing.
It addition, described oils and fats inlet 23 is the enlarging more than main channel 22.Make to inject in bearing block in advance
More oils and fats, greasing reliable operation.
Hub bearing greasing frock of the present utility model in using method is: seeing accompanying drawing 1, hub bearing inner ring is sleeved on
Location is realized on step shaft part, the radial direction through hole external port of the corresponding greasing passage in the gap 81 between two inner rings of hub bearing,
Being passed through in main channel from oils and fats inlet by oils and fats, oils and fats injects in hub bearing along main channel through radial direction through hole.
