Description
Technical field
The utility model belongs to gear and gear ring technical field, is specifically related to a kind of gear/gear circle.
Background technique
In the industrial production, gear and gear ring are widely used in driving mechanism.And gear and gear ring are all utilize the gear teeth to carry out transmission, all at grade, the centre of namely taking turns tooth crest is the same with two ends high at the top of traditional gear teeth.
Tradition the gear teeth be all adopt, the modes such as punching press, forging and stamping and machining are shaped, along with the development of extrusion technique, extruding gear and extruding gear ring also start pendulum and use, and extruding gear and extruding gear ring comparatively conventional art have more standby cost advantage and price advantage.
But when gear transmission, the gear teeth are easy to because of stressed for a long time, or moment impact is excessive is broken, and occurs broken teeth, and wheel between cog, due to long term high temperature friction, lacks lubrication, also there will be noise large, the shortcoming be shortened working life.
Model utility content
The purpose of this utility model is to provide a kind of gear/gear circle, has the function of noise reduction, effectively can improve the working life of gear/gear circle.
For achieving the above object, described in the utility model, a kind of gear, be provided with the gear teeth (1), the cross section of the gear teeth (1) main body is lower large little taper, its key is: the tooth top of the described gear teeth (1) has guiding gutter (1a), and the degree of depth of this guiding gutter (1a) is 1/5 to 1/2 of outside pitch line length; The width of described guiding gutter (1a) is 1/20 to 1/10 of tooth tip face width degree.
Addendum is the radial distance between top circle and standard pitch circle.Top circle is the circle at tooth tip place.Standard pitch circle is the basic circle calculating gear physical dimension in end face, is that circle that groove width is equal with transverse tooth thickness is just standard pitch circle in master gear.For spur gear, on standard pitch circle, modulus and pressure angle are reference value.End face is the plane perpendicular to Gear axis on cylindrical gears.
Described guiding gutter (1a) tooth top or for the groove of both ends open, the enclosed slot of closed at both ends or for one end close, the semienclosed slot of one end open.
Main force bearing point when tooth top position, guiding gutter (1a) place is not the engagement of wheel between cog, therefore tooth top fluting, reserve certain amount of deformation to the gear teeth, can improve the gear teeth life-span.Meanwhile, guiding gutter (1a) can also as the seam that expands with heat and contract with cold, and when working gear temperature is too high, the seam that expands with heat and contract with cold can prevent gear tooth deformation.
Described guiding gutter (1a) is straight-line groove or irregular wire casing.
Lubricating oil is perfused with in described guiding gutter (1a).
Be perfused with reinforced metal in described guiding gutter (1a), the hardness of this reinforced metal is greater than the hardness of the described gear teeth (1) main body.
Lubricating oil is perfused with in guiding gutter (1a); when the gear teeth, gear ring engagement running; lubricating oil can play lubrication; noise reduction, extends the effect in gear teeth life-span, is perfused with reinforced metal; play the effect of skeleton; strengthen tooth top intensity, prevent tooth top to be out of shape excessive, thus protect intensity and the working life of the whole gear teeth.
When guiding gutter (1a) is for straight-line groove, guiding gutter (1a) is 3 ~ 8 degree with the long limit angular range of tooth top.
A kind of gear ring, be provided with the gear teeth (1), the cross section of the gear teeth (1) main body is lower large little taper, its key is: the tooth top of the described gear teeth (1) has guiding gutter (1a), and the degree of depth of this guiding gutter (1a) is 1/5 to 1/2 of outside pitch line length; The width of described guiding gutter (1a) is 1/20 to 1/10 of tooth tip face width degree.
Described guiding gutter (1a) tooth top or for the groove of both ends open, the enclosed slot of closed at both ends or for one end close, the semienclosed slot of one end open.
Described guiding gutter (1a) is straight-line groove or irregular wire casing.
Lubricating oil is perfused with in described guiding gutter (1a).
Be perfused with reinforced metal in described guiding gutter (1a), the hardness of this reinforced metal is greater than the hardness of the described gear teeth (1) main body.Large gear, as boats and ships gear, just needs to be filled the higher molten metal of hardness, has increased the intensity of gear teeth entirety.
When guiding gutter (1a) is for straight-line groove, guiding gutter (1a) is 3 ~ 8 degree with the long limit angular range of described tooth top.What can strengthen tooth top is subject to force intensity, reduces the deformability of tooth top.
When extruding gear or gear ring, guiding gutter (1a) can also the flow direction of guide wire liquid, realizes the reliable control of molten metal, is beneficial to metal forming.
Remarkable result of the present utility model is: provide a kind of gear/gear circle, have the function of noise reduction, lubrication, can improve the intensity of the gear teeth, effectively can improve the working life of gear/gear circle.
