Sprocket igiya rakasimba kana rakataurika rinosangana ne (roller) cheni kutumira mafambiro. A cog-type sprocket vhiri rinoshandiswa kubatidza bhuroka rine mutsindo chaiwo pane chinongedzo cheni kana tambo.

Chimiro chezino che sprocket chinofanirwa kuve nechokwadi chekuti cheni inopinda nekubuda meshing mushe uye nekuchengetedza simba, inoderedza kukanganisa uye kubata kushushikana kwechetani zvinongedzo panguva meshing, uye inofanirwa kuve nyore kugadzirisa.

Iwo akakosha maparamita e sprocket pitch, roller yekunze dhayamita, nhamba yemazino uye mutsara pitch. Indekisi denderedzwa dhayamita, zino tip denderedzwa dhayamita uye zino mudzi denderedzwa dhayamita ye sprocket ndiwo hukuru hukuru hwe sprocket.
Iyo sprockets ine madhayamita madiki inogona kuitwa muchidimbu chimwe; iyo sprockets ine dhayamita yepakati inogadzirwa muwebhu kana mahwendefa ane perforated; masprockets ane madhayamita akakura anogadzirwa muchimiro chakasanganiswa, kazhinji aine ringgiya dzinotsiviwa dzakasungirirwa kuhubhu.

Iyo diki-dhayamita sprocket inowanzo gadzirwa kuita yakakosha mhando, uye yepakati-dhayamita sprocket inowanzo gadzirwa kuita yekutaura ndiro mhando. Kufambisa kubata, kurodha uye kuderedza uremu, gomba rinogadzirwa mundiro yakataura, uye yakakura-diameter sprocket inogona kuitwa mumhando yakabatanidzwa. Mhete uye musimboti wevhiri zvinogona kugadzirwa nezvinhu zvakasiyana.

Izvo zvinhu zve sprocket zvinofanirwa kuve nechokwadi kuti mazino egiya ane simba rakakwana uye kupfeka kuramba, saka zino repamusoro re sprocket rinowanzo batwa kupisa kuti riwane kumwe kuoma.
