Device can accurately measure the rotating speed of forerunner's output shaft.
A kind of forerunner's speed measuring device, including bearing block, it is characterised in that：Spline is provided with by rolling bearing in bearing block
Axle, the front end of splined shaft has for the spline endoporus with forerunner's output shaft spline connection, and the rear end of splined shaft is by elasticity connection
Axle device is connected with speed measuring coder, and speed measuring coder is fixedly mounted on encoder seat, and encoder seat is fixedly mounted on bearing block
Rear end,
The lower end of bearing block is installed with a pair horizontal strokes for being arranged on forerunner's speed measuring device on forerunner's pallet stringer
Beam, is provided with hyoplastron between crossbeam, hyoplastron is provided with the dead bolt for being fixed on hyoplastron on forerunner's yoke crosstie.
The invention can also be employed the following technical solutions：
Preferred technical scheme, additional technical feature is：The encoder seat is provided with the shaft coupling installing hole of radial direction.
The invention has the advantages and positive effects that：
Because the invention adopts above-mentioned technical proposal, tested the speed using encoder, not by surrounding environment influence, kept away
The lightweight by spline housing of laser velocimeter is exempted from and swing that produce is affected, certainty of measurement is high.Using overall splined shaft so that
Population structure compact dimensions, weight is light, it is easier to install manually.Splined output shaft and coding are connected using yielding coupling
Device, can compensate the two coaxiality error, make measurement data more accurate.Forerunner's survey is positioned to coordinate using hyoplastron and crossbeam jointly
The structure of speed variator so that the device is axially and radially located precisely, it is to avoid forerunner's speed measuring device vertical tremor and the cunning from axle
It is de-.
