High-speed casting of metallic foils by the double-roller quenching technique

Journal of Materials Science, 1982
The ability to produce continuous metallic foils by double-roller quenching with a “mechanically-soft” system has been demonstrated. Significant process variables influencing foil dimensions and microstructures were determined for tin and Al-12 wt% Si foils. The foil formation process is controlled by both fluid and heat flow.

Numerical Simulation Research on a New Spinning Process: Double-Roller Clamping Spinning Process

International Journal of Material Forming, 2010
Thin-wall rotary parts with complex flange geometry have been widely used in many equipments, especially industrial fans and blowers. Conventional stamping and welding methods for those parts have some limitations such as low manufacturability, poor quality and low utilization ratio of material. Thus in this paper, a new spinning process, double-roller

DESIGN AND ANALYSIS OF CAM MECHANISM WITH TRANSLATING FOLLOWER HAVING DOUBLE ROLLERS

Transactions of the Canadian Society for Mechanical Engineering, 2015
The pressure angle is one of the primary considerations in designing a cam mechanism since an inappropriate angle may cause excessive sliding loads on the follower. This paper presents a simple yet straightforward method for the design and analysis of a cam mechanism with a translating follower having double rollers.

Contact Finite Element Analysis of Anti-backlash Double-roller-Enveloping Hourglass Worm Gearing

2011 Third International Conference on Measuring Technology and Mechatronics Automation, 2011
The anti-backlash double-roller-enveloping hourglass worm gearing is multi-tooth meshing transmission and it has complex tooth profile. It is difficult to obtain the load distribution among the meshing tooth pairs and the stress distribution along contact line with analytical model.

Dynamics During Speed Ratio Change of a Double Roller Full Toroidal Traction Drive

Volume 4B: Dynamics, Vibration, and Control, 2017
The dynamics of the speed ratio change process of a double roller full toroidal variator (DFTV) is presented. Speed ratio variation process is observed by finding settling time and efficiency during the ratio variation. A numerical model is developed and simulated using computer software.

Specific problems for designing single-disk cam mechanisms with oscillating double roller follower

Mechanism and Machine Theory, 1991
Abstract On starting from the previously established synthesis conditions, we have studied two design problems specific to the kind of mechanisms we are interested in. The first problem, which refers to the continuity of the motion law of the follower is connected with the fact that the motion law can be indepently adopted only for a domain of the ...

Research on axial friction forces induced by automobile double roller tripod joints

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering
The double roller tripod joint (DRTJ) will generate two axial friction forces during the operation, namely the generated axial force (GAF) and the plunging resistant force (PRF). The GAF will cause “Shudder” of the vehicle, and the PRF will cause “Idle booming” of the vehicle.
