Abstract
The present invention discloses a kind of belt tension device, comprises basic part, positioning shaft, outer-hexagonal nut, upper bearing (metal), lower bearing, gland, screw, locking and positioning screw, basic part, expansion tightening wheel; Described basic part is fixedly installed gland by screw, arranges outer-hexagonal nut between described gland and basic part, the arranged outside protuberance of described outer-hexagonal nut, described protuberance upper end is connected with gland by upper bearing (metal); Described outer-hexagonal nut is through gland; The lower end of described outer-hexagonal nut is connected with basic part by lower bearing; Described outer-hexagonal nut matches with the screw thread that described positioning shaft is arranged; Connect with positioning shaft in the screw that described locking and positioning screw is arranged on basic part; Described expansion tightening wheel is arranged on the lower end of positioning shaft.Advantage of the present invention is: structure is simply exquisite, easy to adjust, is convenient to manually-operable, and the V being suitable for general occasion is with tensioner adjustment, and workpiece is easily processed, assembly easily assembles.
Description
Technical field
The present invention relates to technical field of mechanical equipment, is a kind of belt tension device specifically.
Background technique
Existing belt tension device generally adopts worm and gear Tensioning structure, because the processing of worm and gear difficulty, and worm and gear material is expensive, and the process-cycle is long, and installing space size is large again, and virtually adds cost.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of structure simply exquisite, easy to adjust, be convenient to manually-operable, the V being suitable for general occasion is with tensioner adjustment, and the belt tensioner that workpiece is easily processed, assembly easily assembles.Concrete scheme is as follows:
A kind of belt tension device, comprises basic part, positioning shaft, outer-hexagonal nut, upper bearing (metal), lower bearing, gland, screw, locking and positioning screw, expansion tightening wheel; Described basic part is fixedly installed gland by screw, arranges outer-hexagonal nut between described gland and basic part, the arranged outside protuberance of described outer-hexagonal nut, described protuberance upper end is connected with gland by upper bearing (metal); Described outer-hexagonal nut is through gland; The lower end of described outer-hexagonal nut is connected with basic part by lower bearing; Described outer-hexagonal nut matches with the screw thread that described positioning shaft is arranged; Connect with positioning shaft in the screw that described locking and positioning screw is arranged on basic part; Described expansion tightening wheel is arranged on the lower end of positioning shaft;
For reaching better technique effect, described basic part is bed piece.
Advantage of the present invention is: structure is simply exquisite, easy to adjust, is convenient to manually-operable, and the V being suitable for general occasion is with tensioner adjustment, and workpiece is easily processed, assembly easily assembles.
Accompanying drawing explanation
Fig. 1 is scheme of installation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Illustrate the present invention below in conjunction with accompanying drawing, as shown in Figure 1 and Figure 2, the present invention includes basic part 8, positioning shaft 1, outer-hexagonal nut 2, upper bearing (metal) 3, lower bearing 4, gland 5, screw 6, locking and positioning screw 7, expansion tightening wheel 9; Described basic part 8 to be fixedly connected gland 5 by screw 6, between described gland 5 and basic part 8, outer-hexagonal nut 2 is set, the arranged outside protuberance of described outer-hexagonal nut, described protuberance upper end is abutted with gland 5 by upper bearing (metal) 3, and the lower end of described outer-hexagonal nut 2 is connected with basic part 8 by lower bearing 4; Described outer-hexagonal nut 2 matches with the screw thread that described positioning shaft 1 is arranged; Connect with positioning shaft 1 in the screw that described locking and positioning screw 7 is arranged on basic part 8; Described expansion tightening wheel 9 is arranged on the lower end of positioning shaft 1; For reaching better technique effect, described basic part is bed piece.
Principle of the present invention is: after tensioner assembly assembles on part basic part 8, and gland 5 holds down assembly and uses screw 6 to be connected in basic part 8.Be with wanting the V of tensioner and be placed on expansion tightening wheel 9 times, find accurate location, outer-hexagonal bolt 2 is screwed afterwards with inner hexagon spanner, now positioning shaft 1 just down moves (spiral motion is converted into straight line motion), V is made to be with tensioner modification gradually, the radial force of expansion tightening wheel is born by upper bearing (metal) 3, lower bearing 4, finally transfers in basic part 8; After belt is adjusted to appropriate level, screw up with a wrench part positioning screwn 7, carries out final locking and positioning to positioning shaft 1, prevents expansion tightening wheel 9 from vacillating now to the left, now to the right in high-speed motion and rock, and the tensioner of belt has just been adjusted very easily thus.As felt after test run, V is with expanding force inadequate, and V is with skidding, can repeatedly this action adjust.
