The pandemic has led to an explosion of the e-bike market in 2020. In Europe, retailers reported a doubling to tripling of sales figures compared to the previous year. In China, they quintupled. Manufacturers are under pressure to supply enough parts to meet the demand.
E-bike hollow axle shaft
At the heart of this technology is an important component of the drive system, the hollow axle shaft, which transmits the torque from the motor to the chain ring via a gear.
For the machining of the hollow axle shaft, the bore hole and the external diameter are ground on interlinked machines. Tolerances lie in the range of thousandths of a millimetre and, in large-scale production, they are reliably met using Meister Abrasives grinding and dressing tools. The Meister HPL bonding technology has proven to be particularly helpful in establishing this application.
A technical article was recently published that describes these tools and their advantages in detail and illustrates the achievable results with a case study.
