THE concept of a linear drive unit with integrated motor drive is a simple system that has proved to be very popular in the manufacturing industry.
Danaher Motion has now developed the concept even further by focusing on the longevity on the new Wiesel BASELine linear drive unit to provide enhanced reliability in combination with very low maintenance requirements.
Development engineers at Danaher Motion fitted a ball screw drive with low-backlash single nuts into an aluminium profile - the profile can be screwed directly to the machine frame with mounting strips.
This allows for the simple alignment of the linear drive unit and power transmission.
Compact interface between the linear drive unit and the motor called the 'power bridge' now has the same flat design as used on other Wiesel lines and provides numerous mounting possibilities.
With its low-maintenance sliding rail, the Wiesel BASELine is a robust, reliable and easy-to-replace guide system.
The integrated spindle supports offer high dynamic response combined with safe and smooth operation over any travel length.
An innovative 'cover band' reliably protects the mechanical components from dirt and dust.
The bearings are maintenance-free and when the ball screw drive does need lubricating there is an easily accessible nipple on the 'power bridge'. If fitted with the optional trapezoidal screw drive, the unit requires no maintenance.
The new Wiesel BASELine will be available in two popular frame sizes, the WB40 and WB60, each with profile widths of 40mm and 60mm.
Danaher Motion notes that customers who already use the predecessor model Wiesel W00/W02 will find it very easy to migrate to the new Wiesel BASELine.
A replacement model (WBE40/WBE60) with the same external dimensions and a power bridge that has been adapted in line with the W0 series allows for simple replacement without additional engineering costs.
The Wiesel BASELine linear drive unit is available from Treotham Pty Ltd .
