Servo motor 1 is located on motor base 2, and the output end of servo motor 1 is connected to 3 one end of plum coupling；Plum blossom
3 other end of shaft coupling is connect with 4 one end of torque sensor；Torque sensor 4 is fixed in testing base 11, torque sensor 4
The other end is connect by film shaft coupling 6 with output shaft 13；Felt pad 5 is between motor base 2 and testing base 11；Output
Equipped with axis lock 7 and self-aligning ball bearing 8, output shaft 13 is solid by external bearing block 9 and two force snesors 10 for one end of axis 13
Fixed, 13 other end of output shaft is pierced by testing base 11 and connects stern shafting；
Technology explanation:
Off-axis formula is divided into two parts by pedestal from boat instrument overall structure module；
The range of torque sensor and force snesor can be adjusted according to test demand；
Torque sensor uses non-contact torque sensor, the flexibility and carrier-frequency amplifier skill that digital signal is improved
Art combines.
The beneficial effects of the present invention are:
1. present invention measurement portions modular, data reasonable accuracy are high.Certainly the measurement part of the instrument that navigates is using modularization point
Cloth individually bears axial or circumferential deformation using differently strained element, solves the cross-interference issue between thrust and torque；In motor
Insulation processing has been done between sensor modules, has greatly improved the precision of system；
2. overall structure module of the present invention, easy to disassemble and changeable range.Certainly the entirety for navigating instrument uses modularization
Structure design, various components arrangement is clear, does not interfere with each other, is readily disassembled.Meanwhile modular strain unit can easy replacement mark
The axial direction and circumferential strain sensor of pseudotype number, adjust range at any time；
3. security performance of the present invention is high.Should be from boat instrument due to modular design, structure is simple, and stability is high, and tears open
Strain element deformation after point is single, and component is firmer reliable, is conducive to arrange that accurate strain overload protective device, overload performance are super
1500% is crossed, equipment safety and shock resistance is greatly improved in effective protection shafting, propeller.Modular strain unit is equal
It can reach IP67 degree of protection, cooperation all aluminium alloy/stainless steel machinery component can realize full instrument IP67 level of protection, can be latent
Device guarantees that equipment safety is used under boat or water surface model water leakage situation；
4. the present invention runs smoothly, is with small vibration.It should be distributed from boat instrument mechanical structure in modularization, the strain list of modules
Meta structure is simple, and all modules are placed on the stable pedestal of same, and contact surface is small between shafting and each component, therefore in reality
Vibration noise is minimum during testing, and runs smoothly；
5. the present invention has preferable economy.It should be independent research achievement from boat instrument, what domestic laboratory uniformly used
Aggregation type strain-type propeller is Britain Cussons company monopolizing from boat instrument, and several times money can be saved in identical range
Gold, and more accurate data can be obtained.
Detailed description of the invention
Fig. 1 is a kind of overall schematic of oneself boat instrument of the off-axis formula of modularization changeable fluid；
Fig. 2 is structural schematic diagram of the invention.
Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing to the present invention
It is described further:
Fig. 1 is a kind of overall schematic of oneself boat instrument of the off-axis formula of modularization changeable fluid；
Fig. 2 is structural schematic diagram of the invention.Including servo motor 1, motor base 2, shaft coupling 3, torque sensor 4,
It is felt pad 5, shaft coupling 6, axis lock 7, self-aligning ball bearing 8, bearing block 9, force snesor 10, testing base 11, linear bearing 12, defeated
Shaft 13, plug play bolt 14.
The technical scheme of the present invention is realized as follows:
Since operating servo motor 1, servo motor 1 and 4 one end of torque sensor are connected by shaft coupling 3, torque passes
