Two sections of the semi arch of corresponding case, case are the two halves round casing of separation, are connected with into round casing.The shaft coupling by
Spring leaf is set between the gap of power transmission tooth, due to the effect of spring peripheral force, spring caused elasticity when transmitting moment of torsion
Deformation, resonance while the deformation of spring can be avoided, serves effectiveness in vibration suppression；But the driven shaft being respectively charged into left and right axle sleeve
Size with driving shaft is fixed, for testing the reliability of the various sizes of pump of bench test, it is necessary to change different model
Shaft coupling, it is inconvenient to change, and efficiency is low.
Utility model content
Therefore, for it is above-mentioned the problem of, the utility model provides a kind of adjustable shaft coupling, and it mainly solves existing
The driven shaft and the size of driving shaft being respectively charged into technology middle left and right axle sleeve are fixed, for experiment bench test difference
The reliability of the pump of size is, it is necessary to change the shaft coupling of different model, the problem of it is inconvenient to change, and efficiency is low.
To achieve the above object, the utility model employs following technical scheme：A kind of adjustable shaft coupling, including with
The first flange of the output axis connection of motor and the second flange being connected with the rotating shaft of pump, the first flange and the second method
Several corresponding through holes are provided with orchid, the through hole is equipped with resilient key, the axially middle part of the first flange
Rotatable to be provided with positioning mandril, the center screw screw thread on one end of the positioning mandril and the output shaft end face of motor connects
Connect, the other end of the positioning mandril is provided with the decorative pearl on top of an official cap, and the decorative pearl on top of an official cap is resisted against on the centre bore of the rotating shaft of pump, second method
The clamping device of the rotating shaft for clamping pump is provided with orchid.
Further, the clamping device is scroll chuck.
Further, the scroll chuck includes disk body, and three chutes are evenly arranged with the end face of the disk body, described
Sliding block is provided with chute, claw is fixedly installed on the sliding block, the claw clamping part of arc is provided with the claw.
Further, it is provided with elastomer block on the claw clamping part.
By using preceding solution, the beneficial effects of the utility model are：This adjustable shaft coupling passes through first
Flange is locked on the output shaft axle of motor, and the center screw screw thread on the output shaft end face of positioning mandril and motor connects
Connect, second flange is arranged in the rotating shaft of pump, and the rotating shaft of pump is resisted against by the decorative pearl on top of an official cap set on the other end of positioning mandril
Positioning is realized on centre bore, is passing through elastic pin connection first flange and second flange so that the dismounting of shaft coupling, installation side
Just, and by clamping device it is detachably connected the rotating shaft of pump so that the replacing of pump is convenient, is advantageous on quick test experimental bed
The performance of variety classes pump；Further, the claw clamping part of the arc set on claw causes claw clamping part and cylinder
Rotating shaft contact area increase, so as to heighten frictional force between the two, and then increase clamping dynamics；Further, claw
The elastomer block set on clamping part the further frictional force of increase between the two, and the rotating shaft of different size can be clamped.
