Abstract
The invention relates to a torque loading mechanism which comprises a loading bolt, a locking nut, a locking bolt, a self-locking nut, a loading flange and a loading switch-over plate. The loading bolt is screwed from the inside of a threaded hole of the loading flange, abuts against the loading switch-over plate and is locked through the locking nut. Angular displacement occurs to the loading flange and the loading switch-over plate. After a specified torque is reached, the loading bolt is fixed through the locking nut. The loading flange and the loading switch-over plate are fixed through the locking bolt, and accordingly loading of sealed shafting torque is achieved. The torque loading mechanism is simple in structure, convenient to operate, high in accuracy, safe and reliable; the axial size is small, the structure of a test stand is compact, the test rotation speed can be improved, cost is low, machining is easy, cost is less than 1% of a hydraulic loader and an electric loader, and the torque loading mechanism has strong competition advantages.
Description
Technical field
The present invention relates to a kind of torque loading mechanism, for applying required test torque to Dynamic Closed is power test bed, reach after prescribed torque, whole testing table can carry out dynamic rotary test.
Background technology
The power test bed general employing hydraulic torque loader of Dynamic Closed or electric torque loader are to apply moment of torsion to whole sealing axle.These two kinds of load mode advantages are to adjust in real time moment of torsion, but also existent defect.The axial dimension of loader own is long, and causing whole testing table axle is that span is large, and testing table rotating speed cannot improve.Hydraulic torque loader and electric torque loader cost are very high, and the current domestic ripe manufacturer that do not have.
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 loading bolt, set nut, clamping screw, self-locking nut, loading flange and loads transfer panel;
Described loading bolt screws from loading in flange threaded hole, withstands on and loads on transfer panel, and with set nut locking, described loading flange produces angular displacement with loading transfer panel; Reach after prescribed torque with the fixing loading bolt of set nut, with clamping screw is fixing, loads flange and load transfer panel, thereby realizing the loading to sealing Shafting torque.
As a further improvement on the present invention, described loading flange is mutually nested with loading transfer panel.
As a further improvement on the present invention, described loading flange is provided with centrosymmetric two and loads threaded hole.
As a further improvement on the present invention, described loading transfer panel is provided with two groups of symmetrical deep-slotted chip breakers.
As a further improvement on the present invention, described loading flange is provided with symmetrical Liang Zu hole.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, easy to operate, 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, less than 1% of hydraulic pressure loading device and electronic loader, has very strong competitive edge.
