Description
Technical field:
The invention belongs to field of industrial production, be specifically related to a kind of gear stress measurement strain gauge adhesion process.
Background technology:
Existing gear stress measurement strain gauge adhesion technique shortcoming is that to stick on the foil gauge of gear root very large in Meshing Process of Spur Gear holding capacity, vibration, impact, and oil temperature is higher, and foil gauge easily comes off, and the endurance oil resistance is poor.And higher to requirements of installation space, the spiral gear that module is little can't be finished the stickup of foil gauge, and therefore original strain gauge adhesion technology can't realize the long-term on-line monitoring to all gear stress measurements.
Summary of the invention:
The purpose of this invention is to provide a kind of foil gauge for the gear stress measurement in the stickup gordian technique technique of gear root, utilize this technique as guidance, but finish high reliability, the high sensitivity of the stickup Effective Raise gear stress measurement of gear stress measurement foil gauge on gear, the low-response time, also can realize the long-term online reliable monitoring of gear stress simultaneously.
The objective of the invention is to realize in the following manner: gear stress measurement foil gauge; comprise gear; it is characterized in that: on described gear; ground floor is that to be signal data line layer, the 3rd layer be protective seam for insulation course, the 4th layer for insulation course, the second layer; foil gauge is in the inboard of gear; lead terminal is connected side by side with foil gauge; described insulation course is the insulating material such as glue, lacquer and polytetrafluoro film; described signal data line layer line cable external diameter should be (Φ 0.2～Φ 0.5) mm, and the line internal diameter should be (Φ 0.1～Φ 0.3) mm.
The invention has the beneficial effects as follows: gear stress measurement foil gauge is through endurance life-span, heatproof, oil resistant test checking, show that gear stress measurement strain gauge adhesion technical matters is reliable, thereby the design verification ability of Effective Raise cogwheel gearing, improve the cogwheel gearing reliability of operation, prolong its non-failure operation time, and bring considerable economic results in society.In addition, gear stress measurement strain gauge adhesion technique can also be applied in cogwheel gearing gear stress loading general survey examination and long-term on-line monitoring, also can be applied in cogwheel gearing power Even load test and the test of actuated element impact strength etc., have very practical using value.

Embodiment:
With reference to Fig. 1; gear stress measurement foil gauge; comprise gear; it is characterized in that: on described gear; ground floor is that to be signal data line layer 2, the 3rd layer be protective seam 3 for insulation course 1, the 4th layer for insulation course 1, the second layer; foil gauge 5 is in the inboard of gear, and lead terminal 4 is connected side by side with foil gauge 5.Described insulation course 1 is the insulating material such as glue, lacquer and polytetrafluoro film, and described signal data line layer 2 cable external diameter should be (Φ 0.2～Φ 0.5) mm, and the line internal diameter should be (Φ 0.1～Φ 0.3) mm.
1, pasting front surface processes:
Before pasting foil gauge, determine first paste position and mark.Because paste position is in the gear root, the gear root has radian and small volume, can only take manual mode to carry out surface treatment.1) at the paste position place, repairs out (2 * a 2) mm with the group file
2The stickup plane of surface area.2) gluing of surfaces is processed.At first with flint glass paper structural member stickup foil gauge place is carried out the miter angle polishing, then carry out the secondary polishing with fine sandpaper, require obviously groove mark of surface nothing, there is evenly trickle miter angle striped on the surface.In the bruting process, guarantee flatness and the smooth finish on this plane.And draw pin with steel and draw the paster position line.3) cleaning surfaces is processed.Repeatedly clean with chemical acetone or toluene, clean with alcohol at last, until do not have obvious oil stain and dust.The stickup of foil gauge is carried out as early as possible.If paster at once is not coated with last layer vaseline and protects temporarily.
2, strain gauge adhesion:
The lead-in wire of foil gauge should be bent up gently before the paster, in the anti-sticking sheet process spun gold is bonded on the gear field of conjugate action.Can not too exert oneself during with tweezers folder spun gold, in order to avoid the damage spun gold at first will be examined under a microscope the setting-out position that will paste during stickup.Then foil gauge is placed in place to be pasted gently, pushes down gently the termination of foil gauge with the toothpick of skiving, strain gage adhesive has been stained with a fine wire.Be placed on lightly the slit place between strainometer and the beam, glue is understood oneself being drawn among the slit between foil gauge and the tooth root location for paste slowly, waits a moment and can pick up the toothpick that is pressed on the foil gauge, and at this moment paster work can be finished.
The toothpick that is pressed on the foil gauge can not be firmly excessive, otherwise foil gauge is damaged, moreover it is too much unsuitable to click and enter the glue of foil gauge and gear location for paste, and tinsel must be thin, and the dosage of more carefully controlling is more accurate.The curing key of bonding agent is the good temperature of GPRS, time and cycle period, carry out in strict accordance with the technological specification of the curing of gauge bonding agent.In order to prevent strength decreased, insulation breakdown and couple corrosion, on the foil gauge after the curing, should coat the moisture protection layer, moisture barrier adopts the adhesive glue of dilution.
