Instruments for size inspection, rocking type

Rocking type inspection instruments for gears and splines are a cost-efficient solution for single productions and small batches. With a bit of skill, the actual dimension over and between balls, i.e. the highest measurement point, can be found by rocking the instrument. We recommend a Frenco VDA-5 inspection certificate for all VA inspection instruments in order to verify a sufficiently small measuring uncertainty regarding the tolerance to be measured.
Inspection instruments for internal gearing IVA:
The IVA inspection instrument for internal gearing consists of a handle, a measuring head with two measuring ball inserts and a dial indicator. A setting ring with a toothed section is recommended to guarantee a small measuring uncertainty./p>
The measuring head can only be used for a specific size and a specific measuring ball diameter.
The clock face of the dial indicator has been specifically chosen for metrology.
Instrument type    Pitch circle diameter
IVA 0    4 - 15 mm
IVA 1    15 - 28 mm
IVA 2    28 - 130 mm
IVA 3    50 - 330 mm
IVA 4 (with measuring force lift-off)    from 190 mm
Inspection instruments for external gearing AVAL:
The AVAL inspection instrument for external gearing consists of two measuring ball inserts, a dial indicator (measuring force 1N) and a measurement stand (optional).
quick and flexible measurement of the dimension over/between balls,
easier location of the tooth position with measuring force lift-off,
option with height adjustable support for the workpiece,
measuring ball inserts can be interchanged,
measuring pin inserts can also be used (but not interchanged),
two heat insulation plates prevent any heat transfer from the operator's hand.
Calibration is carried out with a sector setting plug.
Instrument type    Pitch circle diameter
AVAL 1    0 - 35 mm
AVAL 2    35 - 70 mm
AVAL 3    70 - 135 mm
AVAL 4    135- 180 mm
