Single Axis Robot SK Series
The HIWIN SK quiet Single Axis Robot with SynchMotionTM Technology offers quieter operation, smooth movement, low particle emission rate, longer service life and superior lubrication.
With the SynchMotionTM Technology, SK Single Axis Robots will be more suitable for industries which require higher speeds and quieter performance.
■ Low noise
■Low particle emission rate
■ Longer service life
■Easy installation and maintenance
With SynchMotionTM Technology, rolling elements are interposed between the partitions of SynchMotionTM to provide improved circulation. Due to the elimination of contact between the rolling elements, collision noise and sound levels are drastically reduced.
Tangent Circulation Technology
Balls enter circulation system by following spiral pathway. It can diminish the impact while balls are entering the circulation system, improve the speed, acceleration, smoothness of traditional external circulation, reduce the noise while balls are entering the circulation system. In so doing, it acts high speed and low noise performance.
The rolling elements enter the circulation system by following the spiral pathway.When compared to the traditional external circulation, the Tangent Circulation Technoloav diminishes the impact caused by the rolling elements entering the circulation system, improving the speed, acceleration and smoothness while reducing the noise.
Incorporating both SynchMotionTMTechnology and Tangent Circulation Technology, the noise reduction is about 3~5 dB during operation.
1. Service Life
Under repeated stress between the raceway and the rolling elements, pitting and flaking will occur as it reaches fatigue failure. The service life of the SK Single Axis Robot is defined as the distanced traveled before any failure of the raceway or rolling elements appear.
2. Nominal Life (L) The service life varies greatly even when the SK units are manufactured in the same way or operated under the same conditions. Forthis reason, nominal life is used as the criteria for predicting the service life of a SKunit. 3. Nominal Life Calculation The calculating formulas are divided into two parts, quideway and ballscrew. The smaller of the two values would be the recommended nominal life of the SK unit. Nominal life formulas for both the quideway and ballscrew depend on several parameters as shown below.
