Abstract
The utility model relates to a transmission component, in particular to a noise reduction meshed type chain. The noise reduction meshed type chain comprises chain blocks, wherein the chain blocks are Y-shaped; a plurality of the chain blocks are spliced with each other so as to form a chain body, and a soft gasket is arranged on an engagement part of each chain block. According to the noise reduction meshed type chain provided by the utility model, the Y-shaped chain blocks have a stable structure and are reliably matched with each other, so that looseness in a movement process is reduced; the gasket is arranged on each chain block, so that the decibel of the noise is reduced. The chain blocks are connected through an independently rotating chain, the shaft provides a stable and reliable connection manner, so that the mechanical friction between the chain blocks and the shaft, the mutual loss between the chain blocks and the shaft, and the mechanically generated radiography are reduced, and the service life is prolonged; tooth holes do not need to be processed in the chain blocks, so that the production process of the product is reduced, and the yield is improved.
Description
Technical field
The utility model relates to a kind of transmission part, relates in particular to a kind of noise reduction and stings tooth-like chain.
Background technique
Parts in big machinery are intricate, and collaborating between parts and parts needs transmission part mutually to coordinate, and these transmission paries are divided into bar, belt, gear, tooth bar, chain etc.Wherein the transmission mode of chain is stable and durable in use, is widely used.But after long-time use, the connected structure between chain stick occurs lax, and chain stick can not closely cooperate, and produces gap, has caused transmission to have stagnation, makes precision equipment lose pinpoint function.In order to address these problems, there are some special chains, as used length coaxial, multiple row chain stick is installed on axle; This pattern reduces the generations in gap by the pressure between many group chain sticks, but this type of mode operation is after long afterwards, and noise is very large, and the necessary whole piece that broken down is changed and cannot be keeped in repair wherein damaging chain stick.In addition monolithic chain stick is widened, at chain stick two ends, slot, the two ends processing projection of the chain stick that expection coordinates, mutually embed and reinforce by bearing pin, chain stick monomer processing technology is complicated like this, need two different process lines to process and could be shaped, processing cost is larger, and market demand is little.And because precision is difficult to control, cause defect rate high.
Model utility content
The utility model provides a kind of noise reduction to sting tooth-like chain for above-mentioned deficiency.
The utility model adopts following technological scheme:
A kind of noise reduction described in the utility model is stung tooth-like chain; Comprise chain stick, described chain stick becomes " Y " shape; Several chain sticks are spliced to form chain body mutually, and the joining place between each chain stick is provided with soft pad.
Noise reduction described in the utility model is stung tooth-like chain, between described chain stick, by axle, is mutually flexibly connected.
Noise reduction described in the utility model is stung tooth-like chain, and described axle is by axis body, and roller bearing forms; On described axis body, along external diameter, offer three arc grooves, place respectively ball in arc groove, ball outside is nested with roller bearing.
Noise reduction described in the utility model is stung tooth-like chain, and described arc groove bottom is provided with through hole, and through hole is connected with oil circuit, and oil circuit communicates with oil duct; One end of described oil duct is provided with fuel oil supply nozzle; Fuel oil supply nozzle is by sealing mouth shutoff.
Noise reduction described in the utility model is stung tooth-like chain, and described Y shape chain stick is comprised of two legs and top joint; The outer surface of described two foots is provided with inside concave surface, and the outer surface of top joint end is provided with inside concave surface; Between described two legs and top joint, be provided with groove.
Noise reduction described in the utility model is stung tooth-like chain, and the opposing side of two described legs is respectively equipped with soft pad; The exterior edge face, both sides of top joint is respectively equipped with soft pad.
Noise reduction described in the utility model is stung tooth-like chain, and the width of described groove is greater than two width between leg.
Beneficial effect
A kind of noise reduction that the utility model provides is stung tooth-like chain, the structural stability of its Y shape chain stick own, and reliable fit, has reduced becoming flexible in its movement process each other; Positioned spacers on each chain stick, reduced noise minute.Between chain stick, by Spindle Links that can independent rotation, axle provides reliable and stable on-link mode (OLM), has reduced the mechanical friction between chain stick and axle, lowers mutual loss between the two, has also reduced the radiography that its machinery produces, and has increased working life; In axle, be provided with oil duct, can to chain, carry out daily maintenance easily, lubricant oil has also reduced ball force of rolling friction within it.Between two chain sticks, coordinate the groove forming, can coordinate the driving of chain wheel, chain stick itself, without processing in addition tooth hole, has reduced the production technology of this product, and yield rate is provided.The utility model is applicable to any machinery, transmission device; Highly versatile.
