Abstract:

A low noise duplex bush chains with split rollers was developed through changing roller structure to reduce noise of bush roller chains. The split rollers could absorb more impact energy, mitigate meshing impact and reduce chain drive noise. The noise generated by different types of duplex bush roller chains was carried out to test in same speed, low noise characteristics of duplex sleeve chains with split rollers was verified. By analysis of testing data, noise level of duplex sleeve chains with split rollers compared with that of the other duplex bush roller chains was reduced by the average

Abstract:

Today, roller chains are most often used in chain transmissions as a transmission body. At the same time, there are no dependencies reflecting the nature of the change in kinematic characteristics as the parts of the chain joints wear out, despite the fact that the kinematic characteristics of a chain with worn hinges differ greatly from the nominal values.

Abstract:

This paper describes an improved chain link tension model for a simple two-sprocket roller chain drive. The model includes modified versions of previous models of the tension in the chain links, together with a new model for low-slack span tensions. The model allows the tension of a link to be calculated at any point in the chain drive more quickly and for a wider range of tight and slack span tensions than before. A new chain efficiency model is formulated, based on the losses due to sliding friction. Coupled with the chain link tension model, this can be used to predict the transmission effi

Based on the elastic model of a long-distance transmission roller chain, the elastodynamic analysis was taken in this paper, which has given unregulated displacement of chains.

Abstract:

A quasi-static chain drive model is proposed. This model, consistent with single speed cycling application, applies to simple two sprocket drives. The kinematics of the transmission is determined, including the capture and release positions of the rollers and the influence of the polygonal effect. The tensions into the links and the contact forces (between rollers and sprocket) are then calculated based on the results of the kinematic analysis. Both chain strands are assumed to be straight and their tension are considered as imposed. An estimate of the roller displacement is proposed using exi

The sleeve of roller chain periodically squeezes the pin during the process of chain transmission. The lubrication oil located in the gap of the sleeve and pin will be pushed out and cannot be restored automatically. The absence of sufficient lubricating oil can cause friction, wear, and even the roller chain failure between the pin and the sleeve. This article presents a novel method and a new type of chain structure to lubricant roller chain with ferrofluids, which is capable of prolonging the service life of roller chain.

It now faces depletion of many of these resources, and potentially serious threats to its few "renewable" resources.

We estimate a multi-country, multi-sector New Keynesian model to quantify the drivers of domestic inflation during 2020–23 in several countries, including the United States.

The key mechanism, the international transmission of demand, supply and energy shocks through global linkages helps us to match the behavior of the USD/EUR exchange rate. The quantification exercise yields four key findings. First,

The NAP used an integrated ‘One-Health’ approach which spanned people, animals, agriculture and the environment, and calls for activities to “identify and assess the sources, pathways, and exposure risks” of AMR. The FSA continues to contribute to delivery of the NAP in a number of ways, including
