The linear guide 402 is rectangular ball linear guide, and linear guide 402 and driven roller mounting plate 404 are solid
It is fixed into a single integrated structure.
Embodiment
The present apparatus is by active roll tube 1, driven roller 8, slide block assembly 4, differential chain block component 6, tension weight 7 and matches readjustment
Locking nub 9 forms.
As shown in Figure 1, 2, active roll tube 1, slide block assembly 4, differential chain block component 6 are fixed on scale body frame 2.Skin
3 sets of band on active roll tube 1 and driven roller 8.Driven roller 8 is mounted on slide block assembly 4, can be moved in slide block assembly 4 or so
It is dynamic, realize that belt 3 is tensioned.Tensioning is fixed on the tensioning wheel 604 of differential wheel assembly 6 with 10 one end of wirerope, after two circles, separately
One end cap is in tension weight 7.There are two counterweight adjusting blocks 9 for installation in tension weight 7, after replacing counterweight adjusting block 9, i.e., adjustable
Whole belt tension adjusts position of two counterweight adjusting blocks 9 in tension weight 7, it is big that belt two sides tensile force can be adjusted
It is small.Differential chain block is fixed on the Step Shaft of differential chain block axis 601 of differential chain block component 6 with 5 both ends of wirerope, both ends difference
It is covered on the pulley sleeve 405 of slide block assembly 4 after 3-5 circle in the same direction on Step Shaft.
As shown in Figure 3,4, slide block assembly 4 is by adjusting screw rod 401, linear guide 402, straight-line guide rail slide block 403, driven voller
Cylinder mounting plate 404, pulley sleeve 405, pulley spindle 406, shaft block ring 407 and needle bearing 408 form.Linear guide 402 with from
Dynamic roller mounting plate 404 is integrally fixed, and driven roller mounting plate 404 is equipped with roller mounting groove 409, passes through adjusting screw rod
Position of the 401 adjustable driven rollers 8 in roller mounting groove 409.Pulley spindle is installed on driven roller mounting plate 404
406, and needle bearing 408 and pulley sleeve 405 are installed on pulley spindle 406, needle bearing is limited using shaft block ring 407
408 positions.Two straight-line guide rail slide blocks 403 are fixed on scale body frame 2, and linear guide 402 and straight-line guide rail slide block 403 are selected
Rectangular ball linear guide, there is dedusting scraping blade etc. thereon, has many advantages, such as that coefficient of friction is small, insensitive to dust.
Therefore, the driven roller 8 that both ends are mounted on two slide block assemblies 4 moves left and right flexibly.
As shown in figure 5, differential chain block 6 is by differential chain block axis 601, deep groove ball bearing 602,603 and of differential chain block mounting base
Tensioning wheel 604 forms.Differential chain block axis 601 is fastened together with tensioning wheel 604 using screw, and passes through two deep-groove ball axis
It holds 602 to be mounted in differential chain block mounting base 603, rotary resistance is small.
The course of work is as follows: belt deformation leads to belt tension after the variation or long-time service of weight of material on belt
After changing, break differential chain block that original belt tension and tension weight 7 generate with steel wire 5 to 4 pulling force of slide block assembly
Equilibrium state, tension weight 7 drive differential chain block axis 601 to rotate, and slide block assembly 4 is moved forward and backward, and make belt tension
4 pulling force of slide block assembly is rebalanced with steel wire 5 with differential chain block.Tension weight 7 is applied to the torque of tensioning wheel 604 and turns to be permanent
Square, differential chain block with steel wire 5 to 4 tensions constant of slide block assembly, so that the belt tension that whole device generates is constant.Due to skin
Band tension one changes, and whole process, that is, dynamic realtime carries out.Therefore, which can realize that belt identical tension is tensioned automatically.
Differential chain block principle in the present invention is the wheel shaft and running block that differential chain block is different-diameter there are two one
At laborsaving jack machinism, as shown in fig. 6, according to force balance principle:
F × R=1/2 × P × (R-r)
So lever ratio I=2R/(R-r)
Due to R ﹥ R-r, very big tensile force can produce using very light weight P thus, and the tensile force is constant all the time.
