Abstract
The utility model belongs to mechanical parts, particularly relating to a vibration and noise reducing gear. The gear consists of a gear body(4) and teeth(1), wherein a gear belly between a dedendum and an excircle of a fixed hole(5) is evenly provided with a plurality of through holes(3) in which foamed aluminum filling materials are arranged in interference fit. The gear can markedly lower mechanical vibration and noise, so that the gear has obvious effect of reducing vibration and noise and prolongs the service life of a machine.
Description
Technical field
The utility model belongs to mechanical parts, particularly a kind of vibration and noise reducing gear.
Background technique
Gear and gear reduction box are all kinds of machineries part parts commonly used, gear transmission, speed change is one of device the most basic in the machinery, therefore, reduce vibration and noise that gear brings, to reducing mechanical vibration and noise, improve mechanical working life, improve working environment and have important desirable meaning and realistic meaning.Vibration and noise that gear produces are result of various factor comprehensive action; The main method of control is to eliminate or weaken the power of enforcement that evokes gear noiose, to vibration, the noise that has produced insulate against sound, measures such as vibration isolation, shielding and elimination.At present, domestic and international measure to the gear noiose vibration control: the firstth, the gear structure optimal design comprises and optimizes profile of tooth, optimal design parameter etc.; The secondth, improve manufacturing process, improve the Gear Processing precision, reduce alignment error etc.; The 3rd is damping control; Said method respectively has pluses and minuses, but as a whole, the effect of vibration and noise reducing is generally undesirable.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of and can alleviate gear weight, the tangible vibration and noise reducing gear of effect of vibration and noise reduction.
The technological scheme that the utility model technical solution problem adopts is: a kind of vibration and noise reducing gear of being made up of gear mass, teeth, be characterized in evenly dividing on the wheel abdomen between tooth root and the fixed hole cylindrical and lay a plurality of through holes, interference fit is equipped with the casting resin of foamed aluminium in the through hole.
The beneficial effects of the utility model are: this gear effect of vibration and noise reduction is obvious, has reduced mechanical vibration and noise significantly, and is very favourable working life to improving machinery.
