Background technology
V belt translation or chaindriven during, along with the use of equipment, it may appear that loosen, swelling device
Use become inevitable, stretcher is holding means conventional on belt, chain transmission system, is characterized in
Keep belt, chain can have suitable tensile force in transmission process, thus avoid belt creep, or
Avoid Timing Belt occur to jump tooth, de-tooth and haul out, or prevent chain-loose, come off, alleviate sprocket wheel,
Chain wear.The structure of stretcher is varied, and it generally comprises stationary structure and elasticity is automatically adjusted knot
Structure, the wherein regulation of the many employings of stationary structure fixedly adjustable formula sprocket wheel belt, the tensioning of sprocket wheel, elastic automatic
Adjustment structure many employings elastomeric element can control belt, the tensioning of chain by automatic rebounding, domestic is automatically adjusted
Chain tensioning device many employings spring structure, and external stretcher many employings rubber components.But typically along with
The use of stretcher, internal spring there will be fatigue, causes tensioner to lose efficacy, and can only more renew rises
Bearing up pulley, causes the biggest wasting of resources.
