Abstract
The invention relates to a detection device for the rotation torque of a hot assembly gear. The detection device comprises a torque wrench, a torsion multiplier, a torsion sleeve and a workpiece to be detected. The workpiece to be detected is composed of a crankshaft and a gear, and is installed on a crankshaft assembly table. The torsion sleeve is fixed to the gear at the rear end of the crankshaft through an internal gear. The torsion multiplier is installed on the torsion sleeve. The torque wrench is installed on the torsion multiplier. Force is applied to the torque wrench with set torque, the torsion sleeve drives the gear to rotate, and therefore the torque of the hot assembly gear in the rotation process is detected. The detection device is simple and reasonable in structure and convenient to use and operate, and can accurately detect the actual numerical value of the rotation torque of the hot assembly gear.
Description
Technical field
The present invention relates to a kind of verifying attachment of moment of torsion, specifically a kind of verifying attachment of hot charging selective gear rotary torque.
Background technology
At present, the gear be fitted on bent axle by hot charging cannot detect moment of torsion during pinion rotation, even if the assembling magnitude of interference meets the requirement of drawing, also likely occurs because of pinion rotation in actual use, causes engine failure.Up to now, the bibliographical information of the verifying attachment of special hot charging selective gear rotary torque is had no.
Summary of the invention
Technical matters to be solved by this invention overcomes the deficiencies in the prior art, provides a kind of rational in infrastructure, manufacture simple, easy to operate, check the verifying attachment of hot charging selective gear rotary torque accurately.
The technical scheme that the present invention solves the employing of its technical matters is: a kind of verifying attachment of hot charging selective gear rotary torque, it includes dial torque wrench, device for providing torque amplification, torsion cover and workpiece to be tested, workpiece to be tested is made up of crankshafts and gears, it is arranged on bent axle assembly bench, it is characterized in that: described torsion cover is fixed on the gear of crankshaft rear end by annular wheel, device for providing torque amplification is arranged on torsion and puts, and dial torque wrench is arranged on device for providing torque amplification; By applying power to the dial torque wrench after setting moment of torsion, reversing cover driven gear and rotating, realizing the inspection of moment of torsion when hot charging selective gear rotates.
Described bent axle assembly bench is also provided with device for providing torque amplification supporting seat.
The present invention is rigidly connected with gear by reversing cover, reversing the power put and transfers to completely on gear, realizing being applied to simulation gear at in-engine stressing conditions, and then realizing the inspection of moment of torsion when hot charging selective gear rotates.The present invention is simple and reasonable for structure, operation, easy to use, can accurately detect hot charging selective gear rotate time moment of torsion actual numerical value.
Accompanying drawing explanation
Fig. 1 is composition structural representation of the present invention.
1. dial torque wrenches, 2. device for providing torque amplification in figure, 3. reverse cover, 4. bent axle assembly bench, 5. device for providing torque amplification supporting seat, 6. bent axle, 7. gear.
Embodiment
As shown in Figure 1, a kind of verifying attachment of hot charging selective gear rotary torque, it comprises dial torque wrench 1, device for providing torque amplification 2, reverses cover 3 and workpiece to be tested etc.Workpiece to be tested is made up of bent axle 6 and gear 7, and it is arranged on bent axle assembly bench 4, and described torsion cover 3 is fixed on the gear 7 of bent axle 6 rear end by annular wheel; Device for providing torque amplification 2 is arranged on and reverses on cover 3; Dial torque wrench 1 is arranged on device for providing torque amplification 2.
Described bent axle assembly bench 4 is also provided with device for providing torque amplification supporting seat 5.Device for providing torque amplification supporting seat 5 plays supplemental support device for providing torque amplification.
When the present invention uses, after dial torque wrench 1 is set a certain moment of torsion, power is applied to dial torque wrench 1.If reverse cover 3 driven gear 7 to rotate, then the torque value of dial torque wrench setting is multiplied by the multiple of device for providing torque amplification, is moment of torsion when gear rotates.The present invention reverses cover 3 and is rigidly connected with gear 7, and transfer on gear 7 completely by being applied to the power reversed on cover 3, simulation gear is at in-engine stressing conditions.By applying power to the dial torque wrench after setting moment of torsion, reversing cover driven gear and rotating, realizing the inspection of moment of torsion when hot charging selective gear rotates.
The present invention is simple and reasonable for structure, operation, easy to use, can accurately detect hot charging selective gear rotate time moment of torsion actual numerical value.
