Cogged V-belts - answer CAN be used to replace conventional v belts.
Ribbed V-belts - answer Require 20% LESS tension
The wedge design of a v-belt - answer Multiplies the gripping force.
Less belt tension - answer Results in increased bearing and belt life.
V-belt Drives - answerCan handle high loads and are much more compact
Sychronous drives - answerUse the engagement of the belt teeth with the teeth on the
pulley.
Sychronous belts - answerDo not depend on friction to transport power
V belts - answerMust not bottom out in the pulley or sheave
V-belts - answerAre the most commonly used belts in the industry
Match numbers - answerProvide a way to match exactly the V-belts used in a multiple
v-belt drive.
Cogged V-belts - answerHave notches molded into the standard V-belts.
FHP V-belts - answerAre intended for infrequent or intermittent use.
Various speed belts - answerUse different numbering systems.
1430V215 - answer14=14/16 or 7/8, 30= 30 degrees, V= Variable speed, and 215= 21.5
inches outside circle.
V-belt Sheaves - answerWILL NEED REPLACEMENT even if the proper v-belt size is
used.
Match belt numbers 51 and 53 - answerIs 2/16 or 1/8 difference in circumference.
A 3v265 belt - answerHas a 26.5 outside circumference.
