Description
Sprocket Gear Wheel Chain Pinion Wheel As Chain wheel Or Sprocket Wheel
Sprocket Gear Wheel Is a Kind Of Wheel With Inlaid Button Sprocket Teeth, Which Is Used To Mesh With The Block With Accurate Pitch On The Pitch Chain Ring Or Cable.
Chain Pinion Wheel Are Widely Used In Chemical Industry, Textile Machinery, Escalators, Wood Processing, Three-Dimensional Parking Garage, Agricultural Machinery, Food Processing, Instrumentation, Petroleum And Other Industries Of Mechanical Transmission.
Tooth Profile Of Sprocket
The Sprocket Tooth Profile Must Ensure That The Chain Enters And Exits Meshing Smoothly And Economically, And Minimize The Impact And Contact Stress Of The Chain Joints During Meshing, And Be Easy To Process.
It Is Composed Of Three Arcs AA, AB, CD And a Straight Line BC, It Is Not Necessary To Draw End Profile On Sprocket Working Drawing. It Is Only Necessary To Indicate On The Drawing That “Tooth Profile Is Manufactured According To 3rgb1244-85”, But The Axle Profile Of Sprocket Should Be Drawn.
Sprocket Structure
Small Diameter Sprockets Are Generally Made Into Integral Type; Medium Diameter Sprockets Are Mostly Made Into Spoke Type, Which Opens Holes On The Spoke Plate For Easy Handling, Loading And Weight Reduction; Large Diameter Sprockets Can Be Made Into Combination Type, And The Ring And Core Can Be Made Of Different Materials At This Time. For Example, c45, Stainless Steel And Other Materials.
Sprocket Material Should Ensure Sufficient Strength And Wear Resistance Of Sprocket Teeth, So Sprocket Teeth Are Generally Heat Treated To Achieve a Certain Degree Of Hardness.
Materials | Heat Treatment | Tooth Hardness | Application Scope |
15# 20# | Carburizing , Quenching , Tempering | 50~60HRC | Z<=25 Sprocket With Impact Load |
35# | Normalizing | 160-200HBS | Sprocket with Z > 25 |
45# 50# ZG310-570 | Quenching , Tempering | 40-45HRC | Chain Wheel Without Severe Impact Vibration And Wear Resistance Requirement |
1SCr 20Cr | Carburizing , Quenching , Tempering | 50-60HRC | High-Power Transmission Sprocket With Z<25 |
40Cr, 3SiIMn, 35CrMo | Quenching , Tempering | 40-50HRC | Important Sprockets Requiring High Strength And Wear Resistance |
A3, A5 | Welding Annealing | 140HBS | Large Sprockets With Medium-Low Speed And Medium Power |
Grey Cast Iron No Less Than HT200 | Quenching , Tempering | 260-280HBS | Sprocket with Z > 50 |
Plywood | Sprocket With High Speed, Stable Transmission And Low Noise |
