Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
In the description of the invention, it is to be understood that term " length ", " width ", " on ", " under ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, it is for only for ease of the description present invention and simplifies description, rather than instruction or the dress for implying meaning
Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limit of the invention
System.In addition, in the description of the invention, " multiple " are meant that two or more, unless otherwise specifically defined.
It should be noted that the V belt translation tensioning apparatus in existing technology, typically uses two kinds of forms, one is setting
A kind of support bar of adjustable distance, support bar one end connection driving wheel are counted, other end is connected with driven pulley, needed to skin
When band is tensioned, the length of support bar is adjusted, and then changes the centre-to-centre spacing of driving wheel and driven pulley, realizes the tensioning of belt.
But which is used, support bar moves the position of driven pulley, so as to cause the transmission system stress of driven pulley and its next stage
Inequality, not only drive mechanism is complicated, can also influence power transmission effect and increase the abrasion of belt.The second is in belt
Side sets tensioning wheel, and belt is tensioned by tensioning wheel.But using which, it is necessary to set extra driving to tensioning wheel
Mechanism and cantilever supporting mechanism, and drive mechanism is needed outside V belt translation region, and then cause the compactness of tensioning apparatus not
Height, complicated, space hold amount is big so that the stationarity and reliability of whole V belt translation reduce.Further, since driving wheel,
The support stiffness of driven pulley and tensioning wheel is weaker, belt very easily occurs by fluctuation, when the normal pressure to belt is in ripple
During peak, the excessive situation for excessively being compressed, easily causing the stuck damage of service life reduction, output motor of belt stress, when to belt
Normal pressure when being in trough, belt stress is too small and then relaxation so that the decline of the stability and precision of V belt translation.
