Description
Technical field
This utility model relates to technical field of automobile, particularly relates to engine wheel system accessory technical field, specifically
Relate to a kind of automatic tensioner.
Background technology
Regulating wheel is the tensioner of V belt translation, can be by use is fixing or self-regulated regulating wheel realizes.Regulating wheel is general
It is arranged in the inner side of slack list, so that band is only by bend in one direction；Meanwhile, for ensureing that small pulley cornerite will not reduce too much, tensioning
Wheel should be installed close proximity to big belt wheel.When using fixing regulating wheel, due to elongation and the abrasion of life span inner belt with start
Machine fuselage and the different thermal coefficient of expansion of belt and the change in size that produces so that tensile force is not the most in operation process for electromotor
Stable.When the centre-to-centre spacing of band can not regulate, regulating wheel can be used band tensioning.If tensile force is excessive, driving means is easy
In producing noise and belt life shortening；If tensile force is too small, belt easily skids, vibrates generation noise, and belt is easy
In wrinkling, damaged, thus the lost of life.Regulating wheel plays the most important in the drive system of automobile engine as can be seen here
Effect.
