CZPT ed German Materials POM Gears
Beskrivelse:
POM (Complete-title: CZPT formaldehyde), is a CZPT plastics of CZPT -facet-chain, large density, high crystalline and linear polymer, which is praised “Plastic Metal”, and has thorough excellent performances, this sort of as: dress in-resistance, substantial hardness, anti-impregnant, very good rigidity (Tensile modulus of elasticity), chemical stability, isolation resistance and dimensional balance.
POM has broadly used in CZPT mobile industries, digital and electric items, commodity, pipeline & fittings, specific apparatus and so on, which can be as an alternative of the bronze, Zinc, tin and other metals.
Besides POM-H, is often copolymerized with ethylene oxide collectively, in order to keep away from the melting of POM content in the substantial temperature. POM-H has the better performances than POM-C in its high crystalline, mechanical toughness and rigidity.
And POM-C has the better performances than POM-H in its lower melting position, temperature balance, fluxion characteristic and machining capacity.
Father much more, POM-H+PTFE, which is created from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the reduced co-efficient of frication, great lubrication, put on-resistance, CZPT -creepage resistance.

EP also sells gear tooth measuring products known as equipment gauges! Gear gauges lessen errors, conserving time and income when determining and purchasing gears. These pitch templates have 9 teams to decide all normal pitch measurements: Diameter Pitch “DP”, Circle Pitch “CP”, Exterior Involute Spline, Metric Modulus “MOD”, Quick Tooth, Good Pitch, Coarse Pitch and Amazing Pitch .
