Belt Driven Bikes

Post by Ako on Mon Aug 17, 2009 12:56 pm

have seen one in the philippines, but i don't remember the brand/model of the bike. meron pa ba sa inyo nakasubok ng belt driven bike? ok ba yung technology na yun? i won't be using it on trails (in case i get one). pang commute lang. thanks.

Spot brand. It was raced by Lasaw's brother sa TLBF SS category - 3rd place, I think. Smile

Doc Ches also has one, but it's not belt driven.

Experience, wala ako nun kasi konti lang talaga meron niyan dito sa atin. Kelan kaya ako maka-experience ng belt? Somebody spank me! What a Face Kidding aside, let's wait, baka may mag-reply. Smile

you know... hehehe pacman... one of the reasons why hindi efficient ang belt sa bisikleta??

SLIPPPAGE.... unless otherwise napakabilis mong paikutin ang crank mo...

kung mag-freewheel ka, pagpadyak mo, medyo may dulas, meron kasing slack side unlike chain and sprocket system, kahit may slack, merong roller and pitch links na kakasa sa ngipin....

correct me if i'm incorrect....

I haven't tried one so I really can't comment. Pero nakita ko na ginamit sa karera at wala naman aberya - nag 3rd pa. Malakas na padyak yun at medyo may kahirapan ang course nung TLBF this year.

hmm... weird, kasi ang sabi naman sa akin ng isang balak mag belt driven, ang advantage daw is the lack of slack side kaya niya gusto. lagi daw taut ang belt, same tension sa taas at baba... but i have yet to try one to know alin nga ang totoo...

boss, this could help: Chain vs Belt

yan ang pinaka the best na nakita ko sa web...

sa school, esp sa Design of Machine Elements, isa yan sa topic, comparing the belt and chain pagdating sa topic na flexible power transmitting elements...

kita jan yung mga advantages at disadvantages ng bawat isa... sa belt drive kasi kailangan mo pai-consider yung angle of contact...sa chain-sprocket drive, yung chordal action...

nice article albert.

Medyo off topic
Sa auto naging diskusyon din iyan ng marami.
Yung transition ng mga makina na gumagamit ng Timing chain at timing belt.
Nuong una puro timing belt, pero ang nissan puro chain, hanggang sa karamihan ng auto ngayon eh timing chain na dahil mas matipid sa Maintenance cost ang chain. mas gusto ng consumer Smile

kaya sa akin,

chain lang.

Hindi naman Siguro ramdam ang weight difference. Pero Durability Siguradong ramdam hehehehe


=====

Yung mga surplus na japan bike may mga belt kaya lang mukhang pang palengke lang at hindi pang isport. Wala daw mabilan ng belt sabi ng mga nakausap ko. Pinapatahi na lang nila

medyo biased lang (gates) yung article:

http://www.gates.com/brochure.cfm?brochure=5262&location_id=6196

(gates is used in both trek and spot belt-driven bikes)


...ang napansin ko na magiging advantage ng belt drive for commuting ay hindi ko masyado papansinin yung pantalon ko. saka pagnagbuhat ako ng bike hindi ako malalagyan ng grasa. Wink

mukang may limitation ang belt sa application sa multi-gear...internal gear siguro pede...pag napatiran ka pa, which i think not impossible to happen...malaking problema.

may nakasubok na ba nyan sa putikan?

talked to a friend this morning who has tried a spot belt drive (he said the bike was just lent to him). kasama ko siya sa la mesa that time. he used it all the way to tower 1, wala naman daw hassle or anything. maganda naman daw yung response nung drive train. pero hindi maputik that time. pero tingin ko ang belt drive problema ito pag sa putik/sa maraming maliliit na bato. and yes, internal gearing lang ang nakita ko na naka belt drive saka single speed.

I think chain can handle shock and heavy loads...

aside from lightweight, medyo madali i-maintain yung belt... yun lang kaso kapag naputikan, e hindi natin alam....

isa pa, walang lubrication..

@ Ako.. mukha nga, marketing strategy...

sabi nila "Another maintenance factor with cost implications is drive component replacement. One of the major weaknesses of a roller chain drive is chain wear resulting in stretching or elongation. Manufacturers recommend roller chain replacement when elongation of approximately 3% has occurred. "

correct! e yung belt ba? ahihihihi to think belts are made of materials that are elastic... heheh.. di ko din alam....

thanks sa article sir albert. babasahin ko po ng maigi... pero malamang aabutin ako ng ilang linggo bago ma-absorb ang laman kasi mukhang nosebleed ako sa pagka-technical nito... hehehehe! Shocked

meron akong nakita sa gran trail makati. mukang magaang nang di hamak yung drive train kasi pwedeng hard plastic o composite materials yung chainring and sprocket. synchronous belt system yung gamit.

para sa akin, mas panalo ang belt. mga naging oto namin belt ang gamit. wala problema basta palitan mo lang sa takdang mileage (80,000 kms). subjected pa sa heat at high rpm abuse (800 min to 6000 max rpm). yung lumang oto namin na toyota corolla, chain ang gamit. pag palit ng chain, palit din ng gears, gastos.

sa bike application, kung ganoon ka-durable yung material ng belt, siguro naman mas tatagal pa kesa sa 80,000 kms ang belt kung max 90 rpm lang padyak. saka marami pang ibang parts ng bike na unang masisira kesa sa belt pag umabot ka ng 80,000 kms.
