	Noen her som som har hatt problemer med drivverket på MZ lok fra Hobbytrade og fått ordnet problemet?

	Hobbytrade har hatt problem med plasten i tannhjulene, disse sprekker etter en stund. Nye akslinger kan skaffes hos en mj forhandler

	Ok, vet du hvilken mj forhandler som kan skaffe?

	Hør med Togbutikken muligens eller andre som selger Hobbytrade.
	A matter of life and death

	Det er ikke sikkert at Hobbytrade støtter gamle produkter mht. reservedeler etter konkursen? Derfor kan det sikkert være vanskelig å skaffe nye tannhjul? Får du tak i gamle plasttannhjul, så sprekker de like lett om noen år. Derfor bruker jeg å erstatte slike plasttannhjul med messingtannhjul. Har funnet en produsent i Polen som faktisk lager det jeg trenger - enten det er til Superline, Topline, Jeco eller Hobbytrade. Disse metalltannhjulene er laget med utmerket presisjon og er rimeligere enn å bytte hjulaksler. Produsenten har hjemmeside: http://www.kkpmo.com/ Bruker å betale på PayPal.

	Hei Kjell Har sett på linken. Hva betyr module i denne sammenhengen?

	"Module" for tannhjul er hvor fin tanningen er. Vanligvis kan tanningen i modelllok variere mellom 0,4 til 0,25. Jeg bruker å måle ytre diameter og telle antall tenner. Dersom ytre diameter stemmer overens med tannantallet, har jeg funnet modulen.

	Der findes en ganske glimrende forklaring på hvad "modul" for tandhjul betyder, her: http://www.fagteori.dk/tandhjul/modulsystemet.aspx Mvh Sømme DK

	Med andre ord: For at bestemme et tandhjuls modul, måler du den ydre diameter i mm, og dividerer med tandhjulets tandantal + 2 tænder. Spørg hvis der er noget du ikke forstår, f eks mit dansk... ;-) Mvh Sømme Edited by ByggerDK - 06 desember 2017 at 11:45

	I følge wikipedia er module definert som: Pitch circle, pitch line Circle centered on and perpendicular to the axis, and passing through the pitch point. A predefined diametral position on the gear where the circular tooth thickness, pressure angle and helix angles are defined. Pitch diameter, d A predefined diametral position on the gear where the circular tooth thickness, pressure angle and helix angles are defined. The standard pitch diameter is a basic dimension and cannot be measured, but is a location where other measurements are made. Its value is based on the number of teeth, the normal module (or normal diametral pitch), and the helix angle. It is calculated as: $d={\frac {Nm_{n}}{\cos \psi }}$ in metric units or $d={\frac {N}{P_{d}\cos \psi }}$ in imperial units.^[27] Module or modulus, m Since it is impractical to calculate circular pitch with irrational numbers, mechanical engineers usually use a scaling factor that replaces it with a regular value instead. This is known as the module or modulus of the wheel and is simply defined as $m=p/\pi$ where m is the module and p the circular pitch. The units of module are customarily millimeters; an English Module is sometimes used with the units of inches. When the diametral pitch, DP, is in English units, in conventional metric units. The distance between the two axis becomes where a is the axis distance, z₁ and z₂ are the number of cogs (teeth) for each of the two wheels (gears). These numbers (or at least one of them) is often chosen among primes to create an even contact between every cog of both wheels, and thereby avoid unnecessary wear and damage. An even uniform gear wear is achieved by ensuring the tooth counts of the two gears meshing together are relatively prime to each other; this occurs when the greatest common divisor (GCD) of each gear tooth count equals 1, e.g. GCD(16,25)=1; if a 1:1 gear ratio is desired a relatively prime gear may be inserted in between the two gears; this maintains the 1:1 ratio but reverses the gear direction; a second relatively prime gear could also be inserted to restore the original rotational direction while maintaining uniform wear with all 4 gears in this case. Mechanical engineers, at least in continental Europe, usually use the module instead of circular pitch. The module, just like the circular pitch, can be used for all types of cogs, not just evolvent based straight cogs.^[28] Jeg synes det er for komplisert å raskt finne modulen til tannhjul. Da produsentens tabeller oftest inneholder ytre radius på tannhjulet, bruker jeg å finne antall tenner og velge et tannhjul der denne diameteren samsvarer med antall tenner. Da finner man lett et tannhjul som passer i tabellene over moduler. En ting man også bør være oppmerksomme på når man bestiller et erstattningstannhjul er akslingsdiameter. Skal tannhjulet sitte fast på akslingen må den være mindre - eller akslingen større. Modellok har oftest akslinger som er 2 - 2,5 og 3 mm. i diameter. Tannhjul er oftest beregnet for å rotere fritt på slike akslinger. For å feste et frittroterende tannhjul til en slik aksling, er det nødvendig å risse spor i akslingen, slik at diameteren på akslingen øker. Mange ganger er det slike spor i akslingen der man skal erstatte et tannhjul - men ikke alltid! Sjekk på forhånd. Jeg bruker også litt Loctite pinneskruelåsing eller mutterlåsing i tillegg for å få tannhjulet til å sitte bom fast.

	Takk for oppklaringer 😁
