隨著P1-P5齒鏈?zhǔn)綗o(wú)級(jí)變速機(jī)使用時(shí)間的積累，已經(jīng)到了老化期，需要調(diào)換內(nèi)部的鏈條。如P0-26節(jié)，P3-29節(jié)，P4-33節(jié)，等等。壓架，鏈輪（4件1組）。直接找上海諾廣無(wú)級(jí)變速機(jī)售后租就可以解決。
無(wú)級(jí)變速機(jī)其他產(chǎn)品1，曲軸型網(wǎng)帶：集中了金屬絲編織網(wǎng)帶的各種優(yōu)點(diǎn)，由于具有彎曲較深的串條，使各個(gè)螺旋盤(pán)條的位置得到正確的定位，因此最大限度地減少網(wǎng)帶的變型和延伸。無(wú)級(jí)變速機(jī)金屬網(wǎng)帶常見(jiàn)形式2，直軸型網(wǎng)帶：無(wú)級(jí)變速機(jī)由左右交替的網(wǎng)條通過(guò)直串條聯(lián)結(jié)而成，該系列網(wǎng)帶網(wǎng)孔較密，網(wǎng)孔間距均勻，能使網(wǎng)帶行走平穩(wěn)。該系列網(wǎng)帶適合于承載體積較小而質(zhì)地相對(duì)較重的輸送線。3，扁絲型網(wǎng)帶：此網(wǎng)帶采用軋扁絲制作．用曲軸型穿條連接，使各個(gè)螺旋盤(pán)條的位置得到正確的定位，因此最大限度地減少網(wǎng)帶的變型和延伸。其做工精細(xì)，表面平整，兩邊平行，材質(zhì)優(yōu)良，經(jīng)久耐用。4，乙型網(wǎng)帶：又稱梯形網(wǎng)帶或一字網(wǎng)，此網(wǎng)帶通常系齒輪傳遞網(wǎng)帶，具有透氣性好的優(yōu)點(diǎn)，拉力均勻，做工精細(xì)，此網(wǎng)帶具有轉(zhuǎn)動(dòng)靈活、平穩(wěn)性好、耐高溫、耐壓力、耐腐蝕、壽命長(zhǎng)等特點(diǎn)。
