Bench of tiredness in rotational bending
|
|
DESCRIPTION
Bench SFT 400 makes it possible to study the various parameters
intervening in the process of tiredness mechanical
Counting of the number of cycle to the rupture.
Variation of alternating loads by application of a variable
effort/rotational bending.
The various shapes of provided test-tubes.
Teaching handbook included.
Designed, manufactured to industrial standards.
The didactic interest of the SFT 400 is directed towards the IUT,
schools of engineers and universities in mechanical sections.

Technical description :
Structure :
- In shaped anodic aluminium of section 45mm*45mm
- 4 feet adjustable shock absorbers
- Transparent cap maintained closed by 2 knurled nuts
Electric box :
- Metal electric box
- Desk of integrating piloting in frontage: Disconnecting switch, circuit
breaker principal, differential, emergency stop, walk general stop with
indicator, walk/engine stoppage, indicator driving state and of general
power supply
- Bill-poster LCD of the number of cycle before rupture/reset by button in
frontage
Revolving part :
- Three-phase asynchronous motor 2850tr/min - 230/400V - 50/60Hz
- Tree guided by ball bearings
- chuck has tightening conical for immobilization of test-tube (key
specific provided)
- 1 inductive detector for counting of the number of cycles of the test.
Device of load application :
- A serrated roller makes it possible to regulate the effort exerted at
the end of the test-tube until 30kg
- A dynamometer makes it possible to measure this effort
- The effort is applied at the end of the test-tube by a bearing related
to the support of load application
- 1 breaking process detector of test-tube/starts the automatic stop of
the counting of the number of cycles
Utilities, dimensions and weight (in kg) :
- Power supply: 400V three-phase + neutral 50/60Hz (other on specific
request)
- Dimensions (L*l*h in mm): 750 X 300 X 600
- Weight: 40kg approximately |
