Generally Speaking, Big Gears And Small Gears Are Measured From The Surface. Firstly, From The Dimension Of The Gear, The Most Obvious Dimension Is Its Diameter. Correctly Speaking, It Should Refer To The Size Of The Top Circle Of The Gear. The Bigger The Diameter Of The Top Circle Is, The Bigger The Gear Is Called The Large Gear.
Large Gear With Cast Teeth
Most Gears Are Machined By Milling And Hobbing Machines. However, In Some Machines With Low Precision Requirements, Cast Gear Is Often Used, Because Cast Teeth Have Better Wear Resistance Than Milling Teeth And Hobbing Teeth, And The Cost Is Low.
In The Case Of a Small Number Of Castings, The Wooden Model Of Car Boards Can Be Used. Based On The Outside Diameter Of The Gear, The Iron Core Boards Are Made Of Boards Embedded In Four Directions, And Then The Inner Core Boards Of The Upper And Lower Boxes Are Made. The Core Heads Of The Axle Holes In The Middle Are Lathed Out, But The Round Holes In The Middle Are Larger Than Those Of The Iron Core Axles.
According To The Circumference Of The Gear, The Gear Can Be Divided Into Several Sections. The Arc Plate Is Made By One Section, And a Number Of Racks Are Nailed. Its Spoke Gear Is Divided Into Upper And Lower Boxes. The Upper Box Ribs Are Dismantled. The Lower Box Ribs And Spoke Gear Are t-Shaped, And The Rounded Corners Are Not Made.
The Maximum Size On The Measuring Rod Is The Maximum Outer Diameter Of The Gear And The Inner Diameter Of The Gear. It Is Easy To Break The Sand Mould Of Teeth When The Moulding Is Lifted, So 3 To 5 Repair Racks Should Be Added To Repair The Shape Of Teeth.
Another Casting Process Of Large Gear With Cast Teeth, Iron Core Plate And Structure Method, Upper And Lower Box Plate, Spoke Gear Of Cross Wheel And Middle Shaft Hole, Are Similar To The Above Methods, Except That The Outer Diameter Of Gear d Should Be Added With a Section Of Mandrel, So Its Measuring Rod Should Be Lengthened To Make The Same Outer Diameter As The Largest One Of Mandrel Head. The Maximum Outer Diameter Of The Circular Arc Plate Of The Shell Frame Is The Same As The Maximum Outer Diameter Of The Core Head.
