It is relatively low.Therefore, it is necessary to which existing chain wheel of motorcycle lid is improved and is optimized.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of chain wheel of motorcycle lid conveniently to oil, with solution
Certainly oil inconvenient problem in the prior art.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of chain wheel of motorcycle lid conveniently to oil includes the entire sprocket wheel of covering and chain made of aluminum alloy materials
Chain wheel cover main body, the chain wheel cover body rim are equipped with the installation edge to form a circle, and installation is equipped with a plurality of mounting ear, peace along outer ring
It is provided with mounting hole on dress ear, it is characterised in that：The installation is equipped with multiple arcs inner fovea part along outside, and the mounting ear setting exists
At arc concave shape portion；The chain wheel cover main body right end is equipped with the conical shell of evagination, and left end is equipped with half shell, the half shell right end arc
Face is transitioned into chain wheel cover main body.
Chain wheel cover main body between the conical shell and half shell is equipped with left narrow right wide protrusion, protrusion right end both sides of the edge
With it is tangent on the outside of conical shell and seamlessly transit, left end extends to half shell right end.
The protrusion is equipped with the corresponding chamfered groove of shape, and chamfered groove right end goes directly on the outside of conical shell, and use is additionally provided in chamfered groove
In the through-hole of installation chain cleaning device.
The chain wheel cover main body is formed using aluminium alloy compression casting, and the mounting hole and through-hole are on the semi-finished product after die casting
Setting.
Raised line is equipped at the top of the conical shell, it is pointed that raised line surrounds sword on conical shell.
The utility model has the beneficial effects that：Entire chain wheel cover main body is firmly fixed on vehicle by bolt across mounting hole
On frame, since mounting ear is arranged at arc concave shape portion after fixing, bolt is hidden in arc concave shape portion, will not exceed chain outward
The edge of wheel cap main body effectively prevents that bicyclist's skin from being scratched by bolt edge or clothing is pulled so as to avoid scratching
Broken drawing crack；The setting of half shell provides the channel that a chain is observed, oiled, to be observed in real time to it, in time
The operations such as oiled, cleaned to chain, can be carried out without dismantling chain wheel cover main body, save the time, improve maintenance
Efficiency.
Description of the drawings
The utility model is described further with reference to the accompanying drawings and examples.
Fig. 1 is the perspective view structural schematic diagram of the utility model.
Specific implementation mode
Referring to Fig.1, a kind of chain wheel of motorcycle lid conveniently to oil of the utility model, including made of aluminum alloy materials
The chain wheel cover main body 1 of entire sprocket wheel and chain is covered, 1 edge of chain wheel cover main body is equipped with the installation to form a circle along 2, installs
It is equipped with a plurality of mounting ear 3 along 2 outer rings, mounting hole 4 is provided on mounting ear 3, the installation is equipped with multiple arcs inner fovea part along 2 outsides
5, the mounting ear 3 is arranged at arc concave shape portion 5；1 right end of chain wheel cover main body is equipped with the conical shell 6 of evagination, and left end is equipped with
Half shell 7, half shell, 7 right end cambered surface are transitioned into chain wheel cover main body 1.Entire chain wheel cover main body 1 passes through peace by bolt
Dress hole is firmly fixed on vehicle frame, and since mounting ear 3 is arranged at arc concave shape portion 5 after fixing, bolt is hidden in arc
In recess portion 5, will not exceed the edge of chain wheel cover main body 1 outward effectively prevents bicyclist's skin quilt so as to avoid scratching
Bolt edge scratches or clothing is torn drawing crack；And the chain wheel portion of the power output end of motorcycle is accommodated by the conical shell of evagination 6
Point, material can be saved to the greatest extent, while ensureing that space is enough；The setting of half shell 7 provide the observation of chain, on
The channel of oil, to be observed in real time to it, the operations such as timely oil to chain, cleaned, without dismantling sprocket wheel
Lid main body 1 can carry out, and save the time, improve maintenance efficiency.
Preferably, the chain wheel cover main body 1 between the conical shell 6 and half shell 7 is equipped with left narrow right wide protrusion 8, protrusion 8
Right end both sides of the edge are tangent with 6 outside of conical shell and seamlessly transit, and left end extends to half shell, 7 right end.Increased by the protrusion 8 of taper
The strong structural strength of chain wheel cover main body 1, effectively prevents it from deforming easily, improves its service life.
As a further improvement of the above technical scheme, the protrusion 8 is equipped with the corresponding chamfered groove 9 of shape, chamfered groove 9
