ROLLER CHAIN SPROCKETS

Transcription

1 ROLLER CHAIN PROCKE ypes an Materials Correct engagement between roller chain an sprocket is require for smooth transmission of roller chain. Appropriate selection of number of teeth (spee ratio), center-to-center istance, an arrangement of sprockets is crucial for service life of a roller chain an a sprocket. Pay ue consieration to the selection of sprockets to avoi ecreasing smooth rotation an transmission efficiency. Finishe prockets FBN (finishe for new JI key) an FB (finishe for ol JI key) sprockets are a version, finishe with shaft bore, key groove, an set screw, of KCM stanar sprocket B-type. Centralize prouction system is employe to ensure high precision an stable quality of proucts which are manufacture in the excellent facilities uner stringent quality control.

In special cases of applications subject to severe abrasion or significant impact loa, carbon steel is use an inuceharene. Inuce harening is require to use in the following operating environment. maller sprockets with 20 teeth or less are use at 1/6 or higher the max spee specifie in Chain Power ransmission able. maller sprockets is use at a spee ratio 4:1 or more. maller sprockets subject to heavy loa at low spee. prockets are use in the atmosphere where teeth are subject to severe abrasion.
