Abstract
The utility model provides a triple gear of a paper shredder, which relates to the gear field. The triple gear is composed of two lateral gears and a middle gear. The two lateral gears and the middle gear are fixed together according to a sequence that the two lateral gears are respectively located on both sides of the middle gear, and the centers of the three gears are provided with through holes. The triple gear of the paper shredder is used as a main force-transferring gear of a paper shredding mechanism, the middle gear made of plastics can reduce wear during engagement movement, the lateral gears are made of metal materials, and the two metal lateral gears clamp the plastic middle gear, thereby guaranteeing the hardness and the strength of the triple gear without easy deformation. In addition, the triple gear as the main component for transferring power has the thicker middle gear made of plastic materials, which can reduce the weight of paper shredder and also reduces the production cost of the shredder.
Description
Technical field
The utility model relates to field of gears, relates in particular to the triple gear that is used for paper breaker.
Background technique
In recent years, deal carefully with for file that will be discarded or the file that relates to company's business secret, paper breaker is applied to common office space more and more widely.
Usually, the shredded paper process of paper breaker is to be rotated by the motor driven gear group, and then gives paper shredding blade with transmission of power, and the pointed tooth of paper shredding blade blade or saw shape tooth are nipped paper and be chopped into fine strip shape or fragment shape.In this shredded paper process, by the chopping resistance that paper produced, enter gear train through paper shredding blade, rotate to gear and bring certain resistance, increase the degree of wear of gear.Usually the gear of paper breaker is a powder metallurgical gear, can produce harsh noise but mesh when rotating between powder metallurgical gear, destroys the quiet and harmonious of working environment, and has increased the weight and the cost of product.
The applying date is on October 27th, 2003, application number is 200320109232.8, name is called the Chinese utility model patent of the plastic gear that accompanies metal that is used for paper breaker, a kind of plastic gear that accompanies metal that is used for paper breaker is disclosed, comprise metal-toothed base as skeleton, described metal-toothed base comprises that the outer ring periphery is shaped on the external toothing of teeth, spoke and ring gear; Open the through hole that is shaped on even radian layout on the spoke of described metal-toothed base, described metal-toothed base periphery is enclosed with the plastic layer that is formed by injection molding gear shape.Though this gear has low noise, high-intensity advantage, this gear production process complexity, often plastic layer weares and teares, but metal frame is also intact, and this moment, the integral replacing gear can cause waste to a certain degree.
The model utility content
For addressing the above problem, the purpose of this utility model is to provide a kind of triple gear of paper breaker, described triple gear is made up of two side gears and a middle gear, described two side gears are in the same place according to the fixed order that two side gears lay respectively at the middle gear both sides with a middle gear, and the center of above-mentioned three gears is provided with through hole.
Described two side gears with middle gear by screw together.
Described middle gear is made of external toothing and spoke, and spoke is provided with the through hole for screw.
Described through-hole wall is provided with screw.
Described middle gear is the plastic material once-through.
Described plastic material is nylon and match steel (English name POM).
On the described side gear with the middle gear spoke on the corresponding position of through hole be provided with through hole for screw.
Described side gear is made by metallic material.
Described gear is made by powdered metallurgical material or the steel impact briquetting.
The thickness of described middle gear is bigger than side gear.
The triple gear of paper breaker described in the utility model is as the main power transmission gear of breaking mechanism, the middle gear of being made by plastic material can reduce wear in the gear motion process, side gear is made by metallic material, two metal side gear clamping plastic cement middle gears, guaranteed the hardness of triple gear, and not yielding.In the process of using, if the triple gear wearing and tearing, the user can change any gear of forming triple gear respectively, does not need unworn part replacement is fallen, and cuts the waste.This triple gear described in the utility model in addition, thicker as the middle gear of transferring power critical piece, and make by plastic material, can alleviate paper breaker weight, reduce the paper breaker manufacture cost.

Embodiment
Please refer to Fig. 1, Fig. 2, a kind of triple gear of paper breaker, described triple gear is made up of two side gears 2 and a middle gear 3, described two side gears 2 and a middle gear 3 are fixed together by screw 1 according to the order that two side gears lay respectively at the middle gear both sides, and the center of above-mentioned three gears is provided with through hole.Described middle gear is made of external toothing 31 and spoke 32, and spoke is provided with the through hole 321 for screw, and through-hole wall is provided with screw, locks by self tapping screw.Described middle gear is nylon material or the once-through of match steel (POM).On the described side gear with the spoke 32 of middle gear 3 on through hole 321 corresponding positions be provided with through hole 21 for screw.Described gear is made by powdered metallurgical material or steel punching press.The thickness of middle gear is bigger than side gear.
Please refer to Fig. 3, the driving gear B6 that breaking mechanism comprises moving motor 4, the driving gear A5 that links to each other with motor, mesh with driving gear A, main paper shredding blade, one are from paper shredding blade, drive main paper shredding blade and from the driving shaft and the driven shaft of paper shredding blade respectively, driving shaft one side is passed operator shaftgear 7 and triple gear, driven shaft one side is passed from knife shaft gear 8, the operator shaftgear with from knife shaft gear engagement, triple gear, driving gear A and driving gear B are separately fixed on the gear carrier 9 by screw.In the shredded paper process of paper breaker, motor drives driving gear A and rotates, driving gear A drives driving gear B, and driving gear B drives triple gear, because triple gear is fixed on the logical axle with the operator shaftgear, the rotation of triple gear has driven the rotation of operator shaftgear, owing to the operator shaftgear with from the knife shaft gear engagement, the rotation of operator shaftgear drives the rotation from knife shaft gear, the rotation of driving shaft and driven shaft, drive main paper shredding blade and, finish the shredded paper process from the rotation of paper shredding blade.
