Description
Technical field
The utility model relates to a kind of bicycle chainwheel technical fields, more specifically, it relates to which a kind of have lubricating machine
The bicycle chainwheel of structure.
Background technique
Currently, bicycle chainwheel in the market, it includes ontology and several sprockets for being set on ontology side.It passes
The bicycle chainwheel of system is then easy to cause the flow velocity of lubricating oil, and then to the lubricant effect of sprocket because oil storage effect is poor
It is deteriorated, be easy to cause the abrasion to sprocket.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide one kind to have oil-bearing structure, structure
Simple and practical bicycle chainwheel.
To achieve the above object, the utility model provides following technical solution: a kind of bicycle with lubricating structure
Sprocket wheel, including ontology and several sprockets being set on ontology side, the ontology is equipped with lubricating structure, lubricating structure
Including the oil storage annular groove being set on ontology, the extension slot being set between oil storage annular groove and sprocket and it is set to extension slot
Two link slots are equipped between oil storage annular groove, connection is formed with confluence intersection point, two connection between two link slots and extension slot
Be in angle is between 80 degree of -120 degree between slot.
By using above-mentioned technical proposal, ontology is equipped with lubricating structure, and lubricating structure includes the storage being set on ontology
Oil ring groove, the extension slot being set between oil storage annular groove and sprocket and be set between extension slot and oil storage annular groove be equipped with two
Link slot, so that each sprocket can be lubricated, is improved good by the oil storage annular groove of setting and the cooperation of extension slot
Practical function increase the area of lubricating oil covering and by the link slot of setting, and two link slots and extension slot it
Between connection be formed with confluence intersection point, then make extension slot and two link slots form multidirectional flow effect, then prevent lubricating oil
Loss, further by angle be between two link slots control 80 degree -120 degree between, then can pass through control connection
Angle between slot carries out the control to lubrication oil flow rate in slot, and then improves good practicability.
The utility model is further arranged to: the sprocket is equipped with guide oil slope, and one end of extension slot and confluence are handed over
Point connection, the other end of extension slot connect with guide oil slope, and the groove width of extension slot from confluence intersection point toward guide oil slope direction by
It is decrescence small.
By using above-mentioned technical proposal, sprocket is equipped with guide oil slope, and one end of extension slot is connect with confluence intersection point,
The other end of extension slot is connect with guide oil slope, is arranged by using above structure, and the effect of Oil Guide is increased, and further will
The groove width of extension slot is gradually reduced from confluence intersection point toward guide oil slope direction, then controls the oil pump capacity of extension slot, and then formed
The effect of continuous lubrication.
The utility model is further arranged to: the oil storage annular groove is wave-shaped or annular in shape, and the slot of oil storage annular groove
Ratio between depth and notch bore is between 1.8-2.
By using above-mentioned technical proposal, oil storage annular groove is wave-shaped or annular in shape, by setting oil storage annular groove to
It is wavy or be in arc-shaped, on the one hand convenient for the lubricating oil flow in oil storage annular groove, on the other hand increase the amount of oil storage, further
By the ratio between the groove depth of oil storage annular groove and notch bore between 1.8-2, on the one hand increase oil storage effect, another party
Face reduces fuel-displaced amount, and then ensures good lubricant effect.
Detailed description of the invention
Fig. 1 is a kind of positive structure diagram of the bicycle chainwheel embodiment with lubricating structure of the utility model.
Appended drawing reference in figure, 1- ontology, 10- oil storage annular groove, 11- extension slot, 12- link slot, 13- confluence intersection point, 2- chain
The gear teeth, 20- guide oil slope.
Specific embodiment
The bicycle chainwheel embodiment with lubricating structure a kind of to the utility model is described further referring to Fig.1.
A kind of bicycle chainwheel with lubricating structure, including ontology 1 and several sprocket wheels being set on 1 side of ontology
Tooth 2, ontology 1 are equipped with lubricating structure, and lubricating structure includes the oil storage annular groove 10 being set on ontology 1, is set to oil storage annular groove
It extension slot 11 between 10 and sprocket 2 and is set between extension slot 11 and oil storage annular groove 10 and is equipped with two link slots 12, lead to
The cooperation for crossing the oil storage annular groove 10 and extension slot 11 of setting improves good reality so that each sprocket 2 can be lubricated
With effect, and by the link slot 12 of setting, the area of lubricating oil covering, and two link slots 12 and extension slot 11 are increased
Between connection be formed with confluence intersection point 13, then make extension slot 11 and two link slots 12 form multidirectional flow effect, then prevent
The loss of lubricating oil further controls angle be between two link slots 12 between spending at 80 degree -120, as shown in figure 1 L1
Shown angle can then carry out the control to oil flow rate is lubricated in slot, and then raising by the angle between control link slot 12
Good practicability.
The utility model is further arranged to, and sprocket 2 is equipped with guide oil slope 20, and one end of extension slot 11 and confluence are handed over
13 connection of point, the other end of extension slot 11 connect with guide oil slope 20, are arranged by using above structure, increase the effect of Oil Guide
The groove width of extension slot 11 is further gradually reduced from confluence intersection point 13 toward 20 direction of guide oil slope, then controls extension by fruit
The oil pump capacity of slot 11, and then form the effect of continuous lubrication.
The utility model is further arranged to, and oil storage annular groove 10 is wave-shaped or annular in shape, by by oil storage annular groove 10
It is set as wavy or in arc-shaped, on the one hand convenient for the lubricating oil flow in oil storage annular groove 10, on the other hand increases oil storage
On the one hand amount, further increases oil storage between 1.8-2 for the ratio between the groove depth of oil storage annular groove 10 and notch bore
On the other hand effect reduces fuel-displaced amount, and then ensure good lubricant effect.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model
It protects in range.
