Device for classifying strain gauges
View Patent ↗A device for classifying strain gauges includes a holder capable of receiving strain gauges and capable of being rotated by a rotating device, the holder being connected to the rotating device by a linking device; and a heater capable of heating the holder and arranged about the mounting, the linking device including a cooling device capable of limiting the heating of the rotating device.
1. Device for classifying strain gauges comprising:
a holder capable of receiving strain gauges and capable of being rotated about a rotation axis by a rotating device, said holder being connected to the rotating device by a linking device;
a heater capable of heating said holder and arranged about said holder;
said linking device comprising a cooler capable of limiting the heating of said rotating device, wherein the cooler comprises a plurality of cooling fins that are each arranged at a different position along the rotation axis so that a first of the plurality of cooling fins is provided farther away from the heater than a second of the plurality of cooling fins.
2. Device for classifying strain gauges according to claim 1 , wherein said linking device comprises a device capable of allowing the expansion of said linking device under the effect of the increase in temperature of said linking device without placing under stress said rotating device.
3. Device for classifying strain gauges according to claim 1 , wherein said heater is formed of an oven heating by radiation.
4. Device for classifying strain gauges according to claim 1 , comprising a secondary cooler capable of improving the cooling of said cooling fins.
5. Device for classifying strain gauges according to claim 4 , wherein said secondary cooler is formed of generators blowing air onto said cooling fins.
6. Device for classifying strain gauges according to claim 1 , wherein said holder is a disc.
7. Device for classifying strain gauges according to claim 1 , wherein the linking device includes two connecting flanges.
8. Device for classifying strain gauges according to claim 1 , wherein the rotating device includes a transmission shaft and one or more ball bearings.
9. Device for classifying strain gauges according to claim 1 , wherein said holder is rotably driven by two transmission shafts arranged on either side of said holder.
10. Device for classifying strain gauges according to claim 1 , wherein said plurality of cooling fins extend radially away from the rotation axis.
11. Device for classifying strain gauges comprising:
a holder capable of receiving strain gauges and capable of being rotated by a rotating device, said holder being connected to the rotating device by a linking device;
a heater capable of heating said holder and arranged about said holder;
said linking device comprising a cooler capable of limiting the heating of said rotating device,
wherein said linking device comprises a device capable of allowing the expansion of said linking device under the effect of the increase in temperature of said linking device without placing under stress said rotating device, and
wherein said holder is rotably driven by two transmission shafts arranged on either side of said holder.
12. Device for classifying strain gauges comprising:
a holder capable of receiving strain gauges and capable of being rotated by a rotating device, said holder being connected to the rotating device by a linking device;
a heater capable of heating said holder and arranged about said holder;
said linking device comprising a cooler capable of limiting the heating of said rotating device, wherein said cooler is arranged on either side of said heater so as to limit the propagation of heat by conduction to said rotating device.
