Description
Technical field
The utility model is related to a kind of dynamometer machine shaft couplings, belong to shaft coupling technical field.
Background technology
Dynamometer machine shaft coupling belongs to power connection parts, is used for the power of testing of electric motors.Per a motor R ＆ D design and
Assembly is required for carrying out carrying out power detection to it after completing, by shaft coupling by the output of the output end of motor and dynamometer machine
Axis docks, different for the motor diameter of axle of different model, and when docking needs to design one-to-one shaft coupling, and dynamometer machine exports
Axis is external splines form, and the processing of shaft coupling internal spline is complicated, and processing cost is higher, and the back-coupling being finished every time also just loses
The value recycled, not reproducible utilization are gone.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of dynamometer machine shaft coupling, the dynamometer machine shaft coupling is logical
It crosses hollow shaft sleeve and inner spline housing by the way of mating be spirally connected so that it is convenient for disassembly and assembly, it repeats and utilizes.
The utility model is achieved by the following technical programs.
A kind of dynamometer machine shaft coupling, it is characterised in that：It is matched in grafting including hollow hollow shaft sleeve, with hollow shaft sleeve
Spline housing and several screws for connecting hollow shaft sleeve and inner spline housing, it is convex that the periphery of the inner spline housing is provided with several
Platform, one end of the hollow shaft sleeve are provided with the slot being connected with boss, and each boss is both provided with screw hole, often
The threaded hole that the one slot bottom setting is correspondingly arranged with screw hole, the inner spline housing are plugged on described by screw fastening
One end of hollow shaft sleeve.
Further, the other end of the hollow shaft sleeve is provided with the keyway for being connect with Devices to test.
Further, there are four the boss settings.
The endoporus of the hollow shaft sleeve and the outer circle clearance fit of inner spline housing.
The axis outer diameter transition of the endoporus and Devices to test of the other end of the hollow shaft sleeve coordinates.
The hollow shaft sleeve is dismantling connection with inner spline housing.
The utility model is beneficial in that：(1) overall structure is simple, and intensity is reliable, easy to process, saves material,
Its inner spline housing detachably reuses, need to treat measured motor tested when, only need to change hollow shaft sleeve, dismount
It is convenient, can seriation, adaptability is good, cost-effective；(2) shaft coupling is rigid connection, and to neutral good, transmission efficiency is high, test
Error is small.

Specific implementation mode
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, Figure 2, Fig. 3, Fig. 4, Fig. 5 and a kind of dynamometer machine shaft coupling shown in fig. 6, including hollow shaft sleeve 1, with it is hollow
Axle sleeve 1 matches the inner spline housing 2 and several screws 3 of grafting, and hollow shaft sleeve is cylindrical shape, and the periphery of inner spline housing 2 is set
Several boss 4 are equipped with, one end of hollow shaft sleeve 1 is provided with the slot 5 being connected with boss 4, and each boss 4 is all provided with
It is equipped with screw hole 6, the threaded hole 7 that each 5 bottom of slot setting is correspondingly arranged with screw hole 6, inner spline housing 2 passes through screw
3 fastenings are plugged on one end of hollow shaft sleeve 1.It is appreciated that boss 4 may be configured as four, it is distributed in the periphery of inner spline housing 2
Side, meanwhile, four slots 5 are again provided on hollow shaft sleeve 1, hollow shaft sleeve 1 is spirally connected with inner spline housing 2 using mating
Mode so that convenient for disassembly and assembly, convertibility is strong.
In the present embodiment, the other end of hollow shaft sleeve 1 is provided with the keyway 8 for being connect with Devices to test, hollow shaft sleeve 1
The other end endoporus and Devices to test axis outer diameter transition coordinate.
Inner spline housing 2 is clearance fit with hollow shaft sleeve 1, easy to disassemble, and transmits torque, structure by boss and screw
Reliably, mechanical efficiency is high.
The hollow shaft sleeve is dismantling connection with the inner spline housing, and inner spline housing is repeatable to be utilized.
In conclusion in the axis outer diameter connection for different Devices to test, hollow shaft sleeve, i.e. hollow shaft sleeve are only needed to change
It connect that one end with inner spline housing and does not need design iterations, need to only change and coordinate that one end with axis.
