Types Of Gears In Robot Parts, Speed Ratios, Advantages Disadvantages Of Gear Devices

A Gear Is A Mechanical Part With Teeth On The Rim That Can Continuously Mesh To Transmit Motion Power . Each Protruding Part On The Gear Used For Meshing Is Called A Gear Tooth, Generally Called A Tooth. These Protruding Parts Are Generally Arranged Radially, The Gear Teeth On The Mating Gears Contact Each Other, Allowing The Gears To Continuously Mesh Operate. The Total Number Of Teeth On The Entire Circumference Of The Gear Is Called The Number Of Teeth. The Following Is A Brief Analysis Of The Types Of Gears, Speed Ratios, Advantages Disadvantages Of Gear Devices In Robot Parts By Huiwen Zhizao .

The Gear Teeth That Can Mesh With Each Other Must Be Of The Same Size, So The Number Of Teeth On The Gears With Larger Diameters Will Be More, The Number Of Teeth On The Gears With Smaller Diameters Will Be Less. However, The Number Of Teeth On The Gears Is The Same During Rotation. For One Rotation Of The Gear With Larger Diameter, The Gear With Smaller Diameter Will Rotate Several Rotations. Therefore, When The Gear With Larger Diameter Drives The Gear With Smaller Diameter, The Rotation Speed Will Become Faster, Which Is Called An Acceleration Gear Device. 

When Gears Are Meshing, They Can Be Parallel Meshing Vertical Meshing. In The Following Figure, Figure 1 Shows Parallel Meshing Figure 2 Shows Vertical Meshing.

Note: When The Gears Are In Parallel Meshing, The Gears Rotate In The Same Plane In Opposite Directions. When The Gears Are In Vertical Meshing, The Gear Transmission Directions Are In Two Vertical Planes, The Rotation Direction Changes, The Direction Of Force Also Changes.

Types Of Gears

   There Are Many Types Of Gears, Which Are Generally Divided Into Bevel Gears, Flat Gears, Crown Gears Turbine Gears According To Their Appearance. The Most Commonly Used Gears Are Bevel Gears Flat Gears.

   Worms Worm Gears Are Often Used To Transfer Motion Power Between Two Intersecting Shafts. The Unique Feature Is That The Worm Can Easily Turn The Worm Wheel, But The Worm Wheel Cannot Turn The Worm. This Is Because The Protrusion On The Worm Is Very Shallow, When The Worm Wheel Tries To Turn The Worm, The Friction Between The Worm Wheel The Worm Will Keep The Worm In Place.

Gear Speed Ratio

Calculate The Gear Speed Ratio. It Is Known That The Radius Ratio Of Gear 1 To Gear 2 Is 3:1. Then The Speed Ratio Of Gear 1 To Gear 2 Is 1:3, The Speed Ratio Of Gear 2 To Gear 3 Is 3:1. Therefore, The Speed Ratio Of Gear 1 To Gear 3 Is 1:1. Summary: Calculating The Output Gear Speed Between Gears That Are Meshed Side By Side Can Skip All The Transmission Processes In The Middle Directly Compare The Radius Ratio Gear Ratio Of The Driving Wheel The Output Wheel.

Advantages Disadvantages Of Gear Devices

Advantage:

1. It Can Accurately Transmit Power. When The Gears Are In Gear Transmission, The Gear Teeth Are Meshed. When The Driving Wheel Rotates One Tooth, The Driven Wheel Rotates One Tooth. This Transmission Method Ensures The Accuracy Of The Movement.

2. Gears Have Large Transmission Force. Gear Transmission Is Achieved Through The Meshing Between Gear Teeth, The Transmission Force Is Greater Than That Of Belts Other Devices.

3. The Structure Is Compact Suitable For Short-Distance Transmission. When Direct Meshing Is Possible, It Can Be Transmitted Through Multiple Gears.

Shortcoming:

1. Loud Noise. The Gear Transmission Force Is Large, So The Noise Generated Is Relatively Loud.

2. Easy To Be Damaged. When Changing Speed, The Gear Teeth Are Easy To Break Due To The Large Transmission Force.

3. Your Fingers May Be Pinched Accidentally.
