Abstract

The utility model discloses an improved chain, which is formed by combining a plurality of chain links. The improved chain is characterized in that: each chain link consists of four link plates, two guide plates and round pins, the four link plates are put together, the two guide plates are symmetrically arranged on the outer sides of the link plates, and the round pins run through the guide plates and the link plates to connect the guide plates with the link plates together; the rear ends of the four link plates between the two guide plates are clamped by the front ends of the two guide plates, moreover, the four link plates are connected in series with the two guide plates through one of the round pins, and both ends of the round pin are riveted; and the front ends of the four link plates in the neighboring chain link are clamped by the rear ends of the two guide plates, moreover, the four link plates are connected in series with the two guide plates through the other round pin, and both ends of the round pin are riveted. The improved chain can effectively prevent the phenomena of chain breaking, tooth breaking and skid from occuring, moreover, the engagement area and the protection area between the improved chain and a sprocket wheel are enlarged, and therefore transmitted power can be uniform and strong; and the mutual abrasion between the parts can be effectively reduced as well, consequently, the service life of the chain is prolonged, and the safety coefficient of the chain is increased.

Description

A kind of improved chain

Technical field

The utility model relates to the chain transmission field, specifically, relates to a kind of improved chain.

Background technique

Because motorcycle possesses light and flexible, easy operating and characteristics such as economical and practical, and is very popular, thereby in many countries and regions, motorcycle is people's main traffic, a means of transportation.What the power transmission of motorcycle adopted is chain transmission.At present, what be used for the motorcycle chain transmission is traditional roller chain, is assembled by bearing pin, sleeve, roller, interior sheet, outer plate and six kinds of unit constructions of snap close.Because its assembling fittings is more, occurs the big phenomenon of build-up tolerance easily, makes chain be elongated easily, even fracture.Motorcycle is in the cruising process, and the unexpected fracture of chain not only can cause the part component of motor impaired, and can cause serious personal injury, even entail dangers to people's life.Therefore, the defective that existing drive chain has is: a little less than the transmit force, power transmission loss is big; Easy-rupturing, working life is short, has great potential safety hazard.

Summary of the invention

The technical problem that the utility model will solve is to overcome above-mentioned defective, and a kind of improved chain is provided, and its transmission is evenly strong, power transmission loss is little, safety coefficient is high, long service life.

For addressing the above problem, the technological scheme that the utility model adopted is:

A kind of improved chain is combined by several chain sections, it is characterized in that: said chain section comprises that four carrier bars that adduct together, two are symmetricly set on the guide plate in the carrier bar outside, are used to run through the round pin that connects guide plate and carrier bar; The front end of two guide plates clamps the rear end of putting four carrier bars in the middle of them, and is cascaded through round pin, and the two ends riveted of round pin is fastening; The rear end of two guide plates clamps the front end of four carrier bars in the adjacent chain section, and is cascaded through round pin, and the two ends riveted of round pin is fastening.

Owing to adopted technique scheme, compared with prior art, the utility model can effectively prevent chain rupture, broken teeth, skidding, and has strengthened occlusal surface and protective surface with sprocket wheel, has guaranteed that power transmission is even, strong and powerful; Can also effectively reduce the mutual wearing and tearing between the component, prolonged the working life of chain, strengthen the safety coefficient of chain.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.
