Abstract
The utility model discloses an universal wheel arc spring, including heliciform spring silk, heliciform spring silk is the arc, and its central radius of circle is 34mm, and the diameter of spiral reduces from well mind -set both sides gradually, and the biggest spiral diameter is 14mm, and minimum spiral diameter is 12.5mm, and the clearance of adjacent spiral reduces from well mind -set both sides equally gradually, goes up the clearance the most greatly and is 7mm, descends the clearance to be 4.7mm the most greatly, the center circle is that yuan at all spiral center places. This novel outward appearance through changing the spring has reduced the wearing and tearing of spring with the arc wall in the use to the life of universal wheel has been improved.
Description
Technical field
This utility model belongs to five metals spring art, is specifically related to a kind of universal wheel arc spring.
Background technology
Universal wheel spring sends power when universal wheel is changed, and is supported the conversion of universal wheel by spring force, but existing linear spring forces bending to embed arcuate groove, and in use spring easily weares and teares, thus causes spring failure to rupture.
Summary of the invention
For the drawbacks described above overcoming prior art to exist, the purpose of this utility model is, it is provided that a kind of universal wheel arc spring, outward appearance is consistent with arcuate groove, the most only by supporting the strength that round dot sends, no longer there is the strength forcing bending bounce-back, improve the service life of product.
The universal wheel arc spring that this utility model provides, including spiral spring silk, described spiral spring silk is arc, and its center radius of circle is 34mm, and the diameter of spiral is gradually reduced to both sides from center, maximum screw diameter is 14mm, the a diameter of 12.5mm of minimum helical, the gap of adjoining spiral is gradually reduced to both sides from center equally, and in maximum, gap is 7mm, maximum lower gap is 4.7mm, and described center circle is that circle at all spiral center places.
The universal wheel arc spring that this utility model provides, simple in construction, it has the beneficial effects that, by changing the outward appearance of spring, in use decreases the abrasion of spring and arcuate groove, thus improves the service life of universal wheel.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of this utility model embodiment.
Figure marks:
1. maximum spiral；2. minimum helical；3. maximum upper gap；4. maximum lower gap；5. center circle.
Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, the universal wheel arc spring providing this utility model is described in detail.
Embodiment
With reference to Fig. 1, the universal wheel arc spring of the present embodiment, including spiral spring silk, described spiral spring silk is arc, its center circle 5 radius is 34mm, the diameter of spiral is gradually reduced to both sides from center, the maximum a diameter of 14mm of spiral 1, a diameter of 12.5mm of minimum helical 2, the gap of adjoining spiral is gradually reduced to both sides from center equally, in maximum, gap 3 is 7mm, and maximum lower gap 4 is 4.7mm, and described center circle 5 is that circle at all spiral center places.
The universal wheel arc spring of the present embodiment, is directly arranged on arc spring in arcuate groove, the most only by supporting the strength that round dot sends, no longer has the strength forcing bending bounce-back, improves the service life of product.
Claims (2)
1. a universal wheel arc spring, including spiral spring silk, it is characterized in that: described spiral spring silk is arc, its center radius of circle is 34mm, and the diameter of spiral is gradually reduced to both sides from center, and maximum screw diameter is 14mm, the a diameter of 12.5mm of minimum helical, the gap of adjoining spiral is gradually reduced to both sides from center equally, and in maximum, gap is 7mm, and maximum lower gap is 4.7mm.
Universal wheel arc spring the most according to claim 1, it is characterised in that: described center circle is that circle at all spiral center places.
