Example 1
Winder/unwinder for textile machines
Task
| Sector: | Textile machines |
| Machine name / machine function: | Winder/unwinder |
| Drive name / drive function: | Centring textile bales during clamping using centre sleeves |
| Ambient conditions / special requirements/ regulations: | Textile machine hall with airborne lint |
| Installation situation / available installation area: | Linear, synchronous adjustment of centre sleeves on both sides |
Solution
| Information about gear type or the transmission element: | Worm gear and trapezoidal screw drive are self-locking together, i.e. no solenoid brakes and controls are required |
| Rated and maximum power: | 0.5 kW , max. 0.9 kW |
| Rated and maximum torques: | 3 Nm , max. 5.5 Nm |
| Rated/maximum speed: | At motor 1,500 rpm |
| Spindle pitch / gear reduction: | 2 mm / 5:1 |
| Compression: | max. 3,000 N |
| Place of installation: | 10 c/h / S3-10 % ED |
| Place of installation: | Very compact installation area |
Customer benefits
Synchronous running of 2 opposing spindle lifting gears without any electronics: 2 three-phase synchronous motors are operated in parallel in the power system and, due to their stable synchronous running, centre the textile bales with a precision down to a tenth of a millimetre.
