Description
Technical field
This utility model is related to technical field of automobile, more particularly to engine wheel system accessory technical field, specifically
It is to be related to a kind of automatic tensioner.
Background technology
Tensioning wheel is the tensioner of V belt translation, can be realized by using fixed or self-regulated tensioning wheel.Tensioning wheel is general
The inner side of slack list is arranged in, so that bend in one direction only received by band；Meanwhile, it is to ensure that small pulley cornerite will not reduce excessively, tensioning
Wheel should be installed close proximity to big belt wheel.During using fixed tensioning wheel, due to life span inner belt elongation and abrasion and start
The different thermal coefficient of expansion of machine fuselage and belt and the change in size that produces so that tensile force is not very in operation process for electromotor
Stable.When the centre-to-centre spacing of band can not be adjusted, can will be with tensioning using tensioning wheel.If tensile force is excessive, driving means are easy
Shorten in noise and belt life is produced；If tensile force is too small, belt is easily skidded, vibrates generation noise, and belt is easy
In corrugation, breakage, so as to the lost of life.Tensioning wheel plays intuitively important in the drive system of automobile engine as can be seen here
