The structural design of a large diametric double roller flatwork ironer
2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011This paper elaborates the working principles of the modern flatwork ironer. The integral structure of a large diametric double roller flatwork ironer is designed. We put forward a new idea of the heating roller, the internal structure of which is transformed from single layer into double layer.

Numerical Simulation of Double Rollers Clamping Spinning Process for Flanging
Advanced Materials Research, 2010Double rollers clamping spinning (DRCS) is a new process to form thin-walled rotary shell parts with complex flange, which adopts two rollers to clamp the workpiece in the forming. Using FE simulation code ABAQUS/Explicit, the 3D simulation model of DRCS process for flanging is established, and the whole DRCS process and material deformation have been ...

The Double Roller Full Toroidal Variator: A Promising Solution for KERS Technology
2012We have analyzed in terms of efficiency and traction capabilities a recently patented toroidal traction drive variator: the so-called double roller full toroidal variator (DFTV). We compare its performance with the single roller full-toroidal variator (SFTV) and the single roller half-toroidal variator (SHTV).

FeSi microcrystalline alloys prepared by single and double roller methods
Journal of Magnetism and Magnetic Materials, 1991Abstract Rapidly quenched Fe 87 Si 13 ribbons have been prepared by single and double roller quenching methods. In both cases, after annealing at the temperature 1100°C the magnetic properties of these alloys are much improved with regard to the soft magnetic characteristics.

Cam mechanisms based on a double roller translating follower of negative radius
Mechanism and Machine Theory, 2016Abstract Constant-breadth cam mechanisms are characterized by the fact that the closure of the cam-follower contact is guaranteed thanks to the geometry and, therefore, auxiliary elements as springs are not necessary. On the other hand, cam mechanisms with a negative radius roller follower allow designing simple machines exerting remarkably high ...

Numerical simulation for double-roller rolling process with deep-cylinder ring
AIP Conference Proceedings, 2013Deep-cylinder rings, as the key mechanical parts of heavy energy equipment, have wide application in nuclear reaction pressure vessels, oil hydrogenation reactors and coal liquefaction devices. Double-roller rolling (DRR) is a new rotary plastic forming technology for deep-cylinder ring manufacturing, which has the advantageous of low energy and ...

Single-disk cam mechanisms with oscillating double roller follower
Mechanism and Machine Theory, 1984Abstract By weakening one of the conditions, which is restrictive, more practicable forms are achievable. The design is based on the choice of a certain part of either the cam profile or of the transmission law. Mathematical analysis leads to a functional equation, which is the same as that in the similar problem with flat-faced follower pairs ...

Research on Cotton Stalk Harvester Based on Double Roller Type
Advanced Materials Research, 2014This paper studies the development status of domestic and foreign cotton stalk harvester. On this basis, a double roller cotton stalk Harvester is designed, which is suitable for small plots. It can pull out the entire cotton stalk through two pairs of reverse rotation of the roller and the forward thrust of tractor.

Design Modification and Analysis of Double Roller Mini Ginning Machine
2018Indian Cotton Ginning Industry is the second largest in the world. Cotton ginning plays very important role of separation of fibers from cotton seed and converts field crop into a saleable commodity i.e. lint. Ginning acts as a bridge between cotton farmer and textile industry. In India, cotton is ginned on double roller gins manufactured domestically.
