The heart gear manufacture cycle is grown, and production cost is high, leverages delivery date and the overall performance of product, existing cast structure it is inclined
Heart gear can not meet the needs of product fast development.
Utility model content
The purpose of this utility model is to overcome above-mentioned technical deficiency, there is provided a kind of eccentric gear, uniform force, uses the longevity
Life length, process and assemble are convenient.
To reach above-mentioned technical purpose, the technical solution of the utility model provides a kind of eccentric gear, including gear ring and abdomen
Plate, the web are provided with a circular eccentric orfice, are provided with eccentric body in the eccentric orfice, axle is provided with the eccentric body
Cylinder, the beam barrel are coaxially disposed with the gear ring, bearing are provided with the beam barrel, is set on the eccentric body positioned at beam barrel side
Have a mounting hole for connecting slave unit, axle center of the mounting hole away from the gear ring, on the web positioned at it is described partially
Position in larger distance is provided with four through holes between heart body and gear ring, and four through holes are with the mounting hole respectively positioned at described
The both sides of beam barrel, four through holes are equal with the distance between the beam barrel axle center, and the eccentric body, mounting hole and four are logical
Kong Jun is distributed on the diameter of the gear ring into axial symmetry, and its symmetry axis is same diameter.
As an improvement four through holes to the distance between the beam barrel axle center is less than the half of the eccentric orfice
Footpath.
As a further improvement, the eccentric orfice is threadedly coupled with eccentric body, the beam barrel and the eccentric body clamping
Connection.
As a further improvement, the beam barrel is provided with the extension installation portion stretched into the mounting hole, the extension
The size and shape of installation portion is adapted and offseted close to the side hole wall of beam barrel with the mounting hole, the beam barrel and the peace
Be provided with three ribs between dress hole wall of the hole away from beam barrel, three ribs on the gear ring diameter into axial symmetry
Distribution, side of the mounting hole away from the beam barrel is provided with supporting plate.
Eccentric gear provided by the utility model, simple in construction, process and assemble is convenient, and sets four through holes to be used to put down
The problem of setting mounting hole to cause gear to lay particular stress on weighing apparatus eccentric body causes gear total quality skewness, uniform force, make
Use long lifespan.
Brief description of the drawings
