Abstract
The utility model discloses a tension-adjusting device, in particular to a tension-adjusting device used for adjusting the tension of a tangential belt. A spindle belt wheel is connected with the tangential belt in a linked mode, and an expanding wheel is installed on a spindle plate through an expanding wheel shaft and tightly abuts against the tangential belt. The tension-adjusting device is characterized in that the expanding wheel is eccentrically installed on the spindle plate. By means of the tension-adjusting device, the eccentric distance of the expanding wheel is reasonably set, meanwhile, gaps and interference magnitudes between the expanding wheel and the tangential belt and between the expanding wheel and the spindle belt wheel are adjusted, on one hand, the tension adjustment on the tangential belt can be effectively controlled, and on the other hand, abrasions caused by excessive abutting and the overlarge tension between the expanding wheel and the tangential belt can be prevented.
Description
technical field:
The utility model relates to a kind of tension-adjusting gear, relates to more specifically a kind of for regulating the tension-adjusting gear of tengential belt tension force.
background technology:
In textile machine, the driving of spindle generally all drives tengential belt to complete by drive motors, along with the development of textile machine technology, one group of drive motors and tengential belt are connected with many group spindles, for the power and the speed that make motor be delivered to each spindle are consistent, need to carry out regulation and control to the tension force of drive motors and tengential belt.
utility model content:
For solving the problems of the technologies described above, the purpose of this utility model is to provide one can effectively regulate tengential belt tension force, can effectively prevent again the tension-adjusting gear of tengential belt and expansion tightening wheel wearing and tearing.
The technical scheme that the utility model is taked is for achieving the above object as follows:
A kind of tension-adjusting gear, is connected between spindle belt wheel and tengential belt, and expansion tightening wheel is installed on spindle plate and with tengential belt and is pushed against by tensioner wheel shaft, it is characterized in that: described expansion tightening wheel bias is installed on spindle plate.
Further arrange and be:
The installing hole of described expansion tightening wheel is eccentric installing hole, and eccentric installing hole departs from the shaft core position of expansion tightening wheel, and between eccentric installing hole and installing hole center, axle center, distance is 3mm.
When expansion tightening wheel is when to minor face, the gap between the outer ring of expansion tightening wheel and the outer ring of spindle belt wheel is 1mm.
When expansion tightening wheel is during in longest edge, the maximum interference amount between the outer ring of expansion tightening wheel and the outer ring of spindle belt wheel is 5mm.
The beneficial effects of the utility model are as follows:
Applicant is through repeatedly putting into practice discovery, as long as rationally arrange by the eccentric distance for expansion tightening wheel, simultaneously, regulate gap and the magnitude of interference of expansion tightening wheel and tengential belt, spindle belt wheel, can effectively control on the one hand the tension adjustment of tengential belt, also can prevent between expansion tightening wheel and tengential belt, because of the wearing and tearing that excessively push against, overtension causes, bringing the inconvenience of replacement simultaneously.Specific as follows: in the time that expansion tightening wheel rotates along the minor face of eccentric installing hole, the tension force of tengential belt is less, and in the time that expansion tightening wheel moves to minor face, the gap between the outer ring of expansion tightening wheel and the outer ring of spindle belt wheel is 1mm.And in the time that expansion tightening wheel rotates along the long limit of eccentric installing hole, just more with suiting of tengential belt, the tension force of tengential belt is larger, make the rotating speed of spindle more stable, more even, in the time that expansion tightening wheel moves to longest edge, the maximum interference amount between the outer ring of expansion tightening wheel and the outer ring of spindle belt wheel is 5mm.
accompanying drawing explanation:
Fig. 1 is the structural representation (installing hole is in expansion tightening wheel shaft core position) of expansion tightening wheel normal mounting;
Fig. 2 be under expansion tightening wheel normal mounting state with the mated condition figure of spindle;
Fig. 3 is the eccentric structural representation of installing of expansion tightening wheel;
Fig. 4 be under the eccentric installment state of expansion tightening wheel with the mated condition figure of spindle when minor face (expansion tightening wheel in);
Fig. 5 be under the eccentric installment state of expansion tightening wheel with the mated condition figure of spindle when longest edge (expansion tightening wheel in);
Number in the figure: 1 is expansion tightening wheel; 10 is the axle center installing hole of expansion tightening wheel; 11 is eccentric installing hole; 2 is tensioner wheel shaft; 3 is spindle belt wheel; 4 is spindle plate; 5 is tengential belt.
the specific embodiment:
Embodiment 1:
As shown in Figure 1 and Figure 2, between spindle belt wheel 3 and tengential belt 2, be connected, expansion tightening wheel 1 is installed on spindle plate 4 by tensioner wheel shaft 2, in this embodiment, the mounting hole site of expansion tightening wheel 1 is in the shaft core position of expansion tightening wheel 1, expansion tightening wheel 1 pushes against on tengential belt 2, and expansion tightening wheel 1 and the magnitude of interference of spindle belt wheel 3 outer rings be one quantitatively---2mm.The shortcoming of this structure is that the adjusting of tengential belt tension force is fixed, and is prone to wearing and tearing between tengential belt and expansion tightening wheel.
Embodiment 2:
Shown in Fig. 3, in this embodiment, between spindle belt wheel 3 and tengential belt 2, be connected, expansion tightening wheel 1 is installed on spindle plate 4 by tensioner wheel shaft 2, and wherein, the installing hole of expansion tightening wheel 1 is eccentric installing hole 11, it is the not shaft core position in expansion tightening wheel 1 of installing hole of expansion tightening wheel 1, but depart from the shaft core position of expansion tightening wheel 1, and eccentric distance is 3mm, between eccentric installing hole 11 and axle center installing hole 10 centers, distance is 3mm.
As shown in Figure 4, because expansion tightening wheel 1 adopts eccentric installation, in the time that expansion tightening wheel 1 rotates along the minor face of eccentric installing hole 11, the tension force of tengential belt 5 is less, and in the time that expansion tightening wheel 1 moves to minor face, the gap between the outer ring of expansion tightening wheel 1 and the outer ring of spindle belt wheel 3 is 1mm.Again in conjunction with shown in Fig. 5, in the time that expansion tightening wheel 1 rotates along the long limit of eccentric installing hole 11, just more with suiting of tengential belt 5, the tension force of tengential belt 5 is larger, make the rotating speed of spindle more stable, more even, in the time that expansion tightening wheel 1 moves to longest edge, the maximum interference amount between the outer ring of expansion tightening wheel 1 and the outer ring of spindle belt wheel 3 is 5mm.
