POM High Precision Gears , 25mm Duplicate Gears for Toy Car Derailleur Straight Teeth

 

 

Duplicate gears are made up of a smaller gear and a bigger gear , both gears are same on modulus but different on number of teeth . speed can be adjusted as different reference circle diameters of both gears .

Precsion

 

Level 9 based on ISO standard .

 

 

Material

 

Plastic duplicate gears are made from plastic POM with white color .

 

 

Application

 

Plastic duplicate gears are mainly used to derailleur that for toy car , plane etc .

Features

 

Good wear resistant

Wear resistant strength still keeps 35MPa or so even item is put 10 J variable load . it is best compared to items that with PA,ABS,HPVC,PS,PC

 

Resistant impact

POM has good impact resistance but inferior to ABS and PC , Impact performance will be down 90% or so if there is breaking on or in product .

 

Self-lubricant

POM parts with F4 , C ,MoS2 ,PE and lubricant elements that improve self-lubricant performance .

 

Stability in dimensions

POM part with good tensile strength and hardness that not easy to be deformed and broken .

 

Resistant Organic solvent

POM parts are resistant for hydrocarbon ,alcohol ,ether ,aldehyde , gasoline ,lubricant and Weak Alkalis .

 

Small creep properties

Creep property rate is 2.3% or so in 20℃,21MPa,3000h . and nearly not be effected by temperature

 

Good insulation

POM items nearly not be effected by temperature and humidity on insulation . insulation is related with the thickness of items , eg when thickness is 0.127mm insulation is 82.7kV/mm,thickness is 1.88mmi insulation is 23.6kV/mm

 

Tips for use

 

POM duplicate gears are easy to be cracked and pulverized outside long-term .

 

Don’t put POM duplicate gears under temperature over 100℃

 

Don’t put POM duplicate gears under circumstance with alkali and oxidant .

 

 

 

More plastic gears we manufactured

 

We provide more plastic gears except duplicate gears , eg , spur gears ,bevel gears ,plastic gears for reducer ,worm gears and involute gear .
