Abstract
The utility model relates to a combined sheet type gear. The adoption technical scheme is that the gear consists of a plurality of thin sheet gears, screws, nuts and spring cushions, wherein the thickness of the thin sheet gears is 0.5 to 5mm; the shape of each thin sheet gear is the same; a plurality of reaming holes are formed in the radial periphery at equal intervals; and the thin sheet gears are connected together through the screws, the nuts and the spring cushions. The gear has the beneficial effects that the gear is made of thin plates, so that 20 percent of material cost can be saved; the thin sheet gears are machined by using a digitally controlled laser cutter, so that the material is not required to be subjected to thermal treatment before machining and is machined and molded at one time, so that the procedure is simple and 50 percent of machining time can be saved; gears with different modulus can be machined by using the same laser cutter, so that the machining generality is high; the requirement on the hardness of the material is not required, so that the materials for manufacturing the gear are more; and when some thin sheet gear is damaged, the thin sheet gear can be replaced and the whole gear is not rejected.
Description
Technical field
The utility model relates to a kind of gear, and especially a kind of improvement of involute spur gearing belongs to the mechanical transmissioning technology field.
Background technique
Existing involute spur gearing is all as a whole.The problem that exists is: 1. gear is adding man-hour, at first needs gear blank is heat-treated, behind reprocessing shaft outlet hole, keyway and the top circle, go out the gear teeth with generating method, and then heat-treat, like this process-cycle of gear longer, processing cost is higher.2. each Gear Processing can only be processed a kind of gear of modulus with cutter, and the cutter versatility is poor.3. when gear material hardness is large, higher to the cutter requirement of strength.4. gear in use if certain takes turns the toothed portion fracture, just causes whole gear to use, and also can't repair, and can only scrap.
Summary of the invention
In order to overcome the above problems, the utility model provides a kind of structure and machine shaping simple, cuts down finished cost, and gear failure is the combined sheet type gear of finishing easily.
The technical solution adopted in the utility model is: the combined sheet type gear is that web gear, screw, nut and the spring washer of 0.5-5mm consists of by some thickness; Each web gear profile is identical, equidistantly on radial circumference has some articulation holes; By screw, nut and spring washer some web gears are linked together.
Above-mentioned combined sheet type gear is established the poor t of being of root circle and gear shaft pore radius, and the preparation method of articulation hole is as follows.
When t≤60mm, the center circumferential l of articulation hole built between root circle and gear axis hole
1On.
When 60mm＜t≤120mm, articulation hole is built in the circumference l of distance root circle 15mm-20mm
2Upper and apart from the circumference l of gear axis hole 15mm-20mm
3On.
When 120mm＜t≤180mm, articulation hole is built in the circumference l of distance root circle 15mm-20mm
2Upper, apart from the circumference l of gear axis hole 15mm-20mm
3Center circumferential l between upper and root circle and axis hole
1On.
When t＞180mm, articulation hole is got the circumference l built in distance root circle 15mm-20mm
2Upper, apart from the circumference l of axis hole 15mm-20mm
3Upper, circumference l
2With circumference l
3Between on the circumference in equal parts of spacing 50mm-100mm.
The beneficial effects of the utility model are: 1. gear material is thin plate, can save 20% cost of material.2. web gear adopts numerical control laser cutter processing, need not material is processed front heat treatment, and the time processing moulding, operation is simple, can save for 50% process time.3. different gears can be with same laser beam cutting machining, and the processing versatility is good.4. add and man-hour the hardness of material is not required, the material that gear can be selected is more.When 5. certain web gear damages, can change, whole gear need not to scrap.
