Iglidur bearings improve rickshaws' comfort
An
Igus UK product story
Edited by the Engineeringtalk editorial team
Dec 1, 2008
Igus is using a Bollywood film to demonstrate how robust its Iglidur plastic plain bearings are.
In Bangalore and other Indian cities, motorised taxi rickshaws are fitted with Igus's lubricant-free polymer bearings.
Motorised taxi rickshaw: the load on the bearings is around three tonnes.
These are used as main hub bearings on the anti-dive device as well as at other bearing points.
The rickshaws have a mechanism that keeps them stable during braking.
This anti-dive device is a connection mechanism with four rods.
The main hub at this connection is guided by an Iglidur RN56 self-lubricating bearing.
The load on the bearing is the load of the vehicle plus the weight of the passengers and the inertia forces, making around three tonnes in total, with a pivoting motion.
A bronze bushing with lubrication grooves and punched holes with graphite filling at the edge was previously used, but the drivers reported that lubrication regularly failed, which meant the bearings wore out quickly and the clearance increased.
Other problems included loud noises, heavy juddering of the handlebars or even tipping of the rickshaw during braking.
Igus developed its Iglidur plastic plain bearings to solve this problem.
Iglidur bearings have improved comfort for the driver and the passengers.
The loads the wear-resistant plastic plain bearings can withstand can be viewed online.
