Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As Figure 1-3.
A kind of self-adapting type belt transmission tensioning mechanism, it comprises the mounting plate 1 be fixed on belt drive unit, described mounting plate 1 is provided with housing 8, housing 8 can directly be fixed on mounting plate 1, also can one end hinge be contained on mounting plate 1, the other end is arranged on mounting plate 1, as Fig. 3 by the fastener assembly 30 through the waist shaped hole 29 on mounting plate 1.Be provided with gear shaft 7 in housing 8, one end of gear shaft 7 is bearing on the clutch shaft bearing 6 that is arranged in housing 8, and the other end is bearing in the perforate of housing 8, as shown in Figure 1.Gear shaft 7 engages with the tooth bar 23 be arranged in housing 8, and one end of tooth bar 23 offsets with same one end of installing spring 24 in the housing, and spring 24 is sleeved on double threaded screw 25, the other end of double threaded screw is provided with the nut 27 for propping up spring 24; The lower end of fork 10 is arranged on gear shaft 7, one end that the lower end of described fork 10 is stretched out outside housing by bolt 22 and gear shaft 7 is connected, simultaneously, stretch out in the lower end of fork 10 and gear shaft 7 between the one end outside housing and index pin 9 is installed, the lower end surface of fork 10 and gear shaft 7 one end of stretching out outside housing are provided with the indexing trough inserted for index pin 9, index pin 9 inserts in different indexing troughs, the setting angle difference of fork 10 can cause the height of fork upper end to change, and realizes the adjustment of belt tension.The upper end of fork 10 is provided with belt wheel 15, and belt wheel 15 is arranged on bearing support 14, is provided with the second bearing 12 in bearing support 14, and bearing pin 11 to be arranged in the second bearing 12 and to be fixed on the upper end of fork 11 and to be fixed by Cock screw 28, as shown in Figure 2.In the outside of the second bearing 12, bearing stop ring 13 is installed.
Working principle of the present utility model is:
Together with bearing support 14 is fastened by bolts with belt wheel 15, bearing support 14 is equipped with the second bearing 12, bearing support 14 can be made to rotate freely on bearing pin 11 together with belt wheel 15.The hole interference fit of bearing pin 11 and fork 10 one end, Cock screw 28 plays the role of positioning, and the other end and the gear shaft 7 of fork 10 can along the longitudinal center line synchronous rotaries of gear shaft 7 under the effect of bolt 22 by index pin 9.Gear shaft 7(gear shaft 7 is installed in the hole of housing 8, formed with hole on this housing and be rotatably assorted, the other end of gear shaft is equipped with clutch shaft bearing 6, another fulcrum as rotating) be meshed with tooth bar 23, one end of tooth bar 23 is provided with spring 24, being installed in housing 8 with hour rack 23 can only moving axially along spring 24, when gear shaft 7 is rotated counterclockwise, the tooth bar 23 be meshed with gear shaft 7 moves to the direction away from gear shaft 7, spring 24 is compressed, under the compression force of spring 24, bearing pin 11 on fork 10 produces a relative circular arc displacement (center line of circular arc is the central shaft of gear shaft 7), this is displaced through belt wheel 15 pairs of belts and produces impacting force, thus realize the tensioning of belt.
On housing 8, mounting hole one end is circular hole, the other end is circular arc waist-shaped hole, can the size of tension adjusting easily, when still cannot meeting in housing 8 place tension adjusting size, can demounting bolt 22, adjustment index pin 9 draw-in groove position on fork 10 meets, certainly, because tension force size is provided by spring 24, the spring changing different elastic force also can adjust the size of tension force.When wearing and tearing appear in belt, when V belt translation is comparatively lax, spring 24 meeting release portion decrement, realizes the auto-tensioning of belt wheel, without the need to manual tune.
The axial alignment of belt wheel 15 belt grooves can increase pad and regulate easily at the two ends of mounting plate 1.
During the utility model is suitable for, the flat rubber belting of small-power transmission, vee belt, the multiple V belt translation such as toothed belt.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
