Background technology
In automobile bench test technology, motor is widely used as prime mover.Car test bench in the process of running,
Motor output shaft end connects load after being connected with shaft coupling, realizes transmission of the torque from motor to load.Measurement motor is defeated
When going out the torque at end, it is necessary to torque sensor is installed between shaft coupling and load, its range meets the motor of all experiments
The measurement request of output end moment of torsion.So, when need the experiment of motor output high torque, existing torque sensing
Device can provide higher measurement accuracy；And when the experiment for carrying out needing motor to export smaller moment of torsion, existing moment of torsion passes
Sensor is because range crosses senior general and causes the obvious reduction of measurement accuracy.Small-range high accuracy torque sensor is now needed to use to enter
Row torque measurement, to obtain higher measurement accuracy.Conventional method is in the examination for carrying out needing motor to export smaller moment of torsion
Before testing, existing torque sensor is first disassembled, then small-range high accuracy torque sensor is installed, is then tested.Experiment
After the completion of, then small-range high accuracy torque sensor is disassembled, reinstall existing torque sensor.This replacing torque sensing
The method of device is required for carrying out disassembly and installation operation to existing torque sensor and small-range high accuracy torque sensor, time-consuming
Length, efficiency are low, and repeatedly the assembly and disassembly to existing torque sensor easily reduce the peace of existing torque sensor because of thread abrasion
Fill precision.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, there is provided a kind of torque sensor installs structure additional.Routine is more
The method of torque sensor is changed due to being required for dismantling to existing torque sensor and small-range high accuracy torque sensor
And installation operation, cause time-consuming length, efficiency low.Therefore, if not carrying out disassembly and installation operation to existing torque sensor, only
Before the experiment for carrying out needing motor to export smaller moment of torsion, small-range high accuracy is installed additional between existing torque sensor and load
Torque sensor；Small-range high accuracy torque sensor is disassembled after the completion of so testing.This method is only needed to small
Range high accuracy torque sensor carries out plus assembly and disassembly, and efficiency improves.Flange type torque sensor is being used as existing torsion
Square sensor and under occasion of the shaft type torque sensor as small-range high accuracy torque sensor, when need in existing flange form
When installing shaft type torque sensor between torque sensor and load additional, installation can be quickly and easily realized, and the rigidity of structure carries
Height, operation stability improves, using reliable；Safety of workers can be protected by installing structure additional；The shaft type torque sensor measurement of installation
Accurately；When needing to remove the shaft type torque sensor installed additional, part convenient disassembly is installed additional；Avoid passing existing flange form moment of torsion
The assembly and disassembly operations of sensor, improve efficiency.

One end connected by flat key；The other end of shaft type torque sensor is connected with load end sleeve flange by flat key.Transition disc
End the distance between sleeve flange and load end sleeve flange are more than shaft type torque sensor total length and shaft type torque sensor
The difference of both sides outrigger shaft total length so that shaft type torque sensor transition disc end sleeve flange and load end sleeve flange it
Between can be moved from one lateral load end sleeve flange side of transition disc end sleeve flange.
Support one end is mounting flange face, and internal stent is provided with the base of two bearing blocks；Load end sleeve flange and
The inner surface setting of transition disc end sleeve flange has keyway, is connected with the shaft type torque sensor of installation by flat key；Positioned at axle
The outer surface of that section of load end sleeve flange between formula torque sensor and bearing is provided with screw thread, connects with double round nut screw threads
Connect；The outer surface for that section of transition disc end sleeve flange being symmetrically located between shaft type torque sensor and bearing is provided with spiral shell
Line, it is threadedly coupled with double round nuts；Sleeve and sleeve are respectively fitted over transition disc end sleeve flange, on load end sleeve flange；Axle
Terminal block circle and shaft type torque sensor are fixed by screw；Bearing and bearing are respectively fitted over transition disc end sleeve flange, load end
On sleeve flange, and it is matched.
When not installing shaft type torque sensor additional, the torque of motor output is measured by existing flange type torque sensor.Add
After installing shaft type torque sensor, the torque of motor output first obtains the number of low precision by existing flange type torque sensor measurement
Value, then high-precision numerical value is obtained by the shaft type torque sensor measurement installed additional, then passed through through transition disc, transition disc end sleeve flange
Load end sleeve flange is output to load.
The effect of the present invention is as follows：
The present invention uses said structure, and because support and motor are connected, the shaft type torque sensor of installation passes through bearing block
Supporting, and then connected by support with the flange of motor and multiple tie points are provided, the rigidity for installing structure additional is improved, structure is being transported
Stability improves during row, and the amplitude vibrated in revolution at a high speed is obviously reduced, using reliable；What upper encloser and support were formed
Housing shields jointly, prevents structure member from throwing away injury worker when high-speed rotation breaks down, and protects safety of workers；
Because shaft type torque sensor can be from transition disc end sleeve method between transition disc end sleeve flange and load end sleeve flange
A blue lateral load end sleeve flange side is moved, and compared to the installation method of fixed shaft type torque sensor, is transported in high speed
Row causes can avoid producing larger additional bending moment under the operating mode of heating, realize that the measurement to moment of torsion is accurate；It is whole to install knot additional
The installation of structure, convenient disassembly, the assembly and disassembly to existing flange type torque sensor are avoided, not only increase efficiency, and avoid
Because the reduction of the installation accuracy of existing flange type torque sensor caused by thread abrasion.
