Abstract
The invention relates to a torque loading mechanism which comprises a loading rod, a suspension weight, a driven shaft and a driving shaft. The loading rod is sleeved on a flange of the driving shaft. The suspension weight applies torque on the driving shaft. The driving shaft and the driven shaft are tightly locked through a fastening piece. Rectangular spline or trapezoidal spline can be respectively processed on the loading rod and the flange of the driving shaft. Uniformly distributed arc grooves are processed on the flange of the driving shaft. Uniformly distributed holes are processed on the flange of the driven shaft. The mechanism disclosed by the invention has the advantages of simple structure, high accuracy, safety, reliability, smaller axial size, low cost and easiness for processing. A test bed is compact in structure. The test rotation speed can be increased.
Description
Technical field
The present invention relates to a kind of torque loading mechanism, be used for applying required test torque to Dynamic Closed is power test bed, moment of torsion apply complete after, available securing member locking torque, then whole testing table carries out the dynamic rotary test.
Background technology
It is to apply moment of torsion to whole sealing axle that common dynamic circulating power testing table adopts hydraulic torque loader or electric torque loader.The shortcoming that these two kinds of load modes exist is that the axial dimension of loader own is long, and causing whole testing table axle is that span is large, and the testing table rotating speed can't improve.Hydraulic torque loader and electric torque loader cost are very high, and there is no at present ripe factory.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus provide a kind of simple and reliable, can be to the power test bed torque loading mechanism that applies moment of torsion of Dynamic Closed.
According to technical scheme provided by the invention, a kind of torque loading mechanism comprises load bar, hangs counterweight, driven shaft, driving shaft, described load bar is enclosed within on the flange of driving shaft, carrys additionally counterweight driving shaft is applied moment of torsion, with securing member, driving shaft and driven shaft is locked.
Be processed with respectively rectangular spline or trapezoid spline mating engagement on the flange of described load bar and driving shaft, can freely enter and withdraw from engagement.Be processed with uniform deep-slotted chip breaker on the flange of described driving shaft.Be processed with uniform hole on the flange of described driven shaft.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, accuracy is high, safe and reliable; Axial dimension is very little, and test platform structure is compact, and test speed can improve; With low cost, be easy to processing, cost has very strong competitive edge less than 2% of hydraulic pressure loading device and electronic loader.
Description of drawings
Fig. 1 is axial view of the present invention.
Fig. 2 is vertical view of the present invention.
Embodiment
Following the present invention is further described in connection with the enforcement in accompanying drawing:
As shown in Figure 1, 2, comprise load bar 1, counterweight 2, driven shaft 5, driving shaft 6 and securing member 7.
Be processed with respectively rectangular spline or trapezoid spline 3 mating engagement on the flange of described load bar 1 and driving shaft 6, can freely enter and withdraw from engagement.Load bar 1 is enclosed within on the flange of driving shaft 6, hangs counterweight 2 and can apply moment of torsion to driving shaft 6 on load bar 1.Be processed with uniform deep-slotted chip breaker 4 on the flange of driving shaft 6, be processed with uniform hole on the flange of driven shaft 5, securing member 7 is contained in the hole.When applying moment of torsion, driving shaft 6 reverses with respect to driven shaft 5, and deep-slotted chip breaker 4 can guarantee both free relative torsions.After moment of torsion applies and puts in place, with spanner, securing member 7 is tightened, driving shaft 6 and driven shaft 5 namely are locked.Counterweight 2 is unloaded, withdraw from load bar 1, axle is to rotate freely.
