Abstract
The present invention relates to a kind of torque loading mechanism comprises loading bolt, locking nut, clamping screw, self-locking nut, loading flange and loads transfer panel; Described loading bolt screws from loading in flange screwed hole, withstands on and loads on transfer panel, and with locking nut locking, described loading flange produces angular displacement with loading transfer panel; After reaching prescribed torque, fix loading bolt with locking nut, load flange and load transfer panel with clamping screw is fixing, thus the loading of realization to sealing Shafting torque. The present invention is simple in structure, easy to operate, the degree of accuracy is high, safe and reliable; Axial dimension is very little, test platform structure compactness, 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 advantage.
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 stand 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 stand axle is that span is large, and testing stand 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, locking nut, clamping screw, self-locking nut, loading flange and loads transfer panel;
Described loading bolt screws from loading in flange screwed hole, withstands on and loads on transfer panel, and with locking nut locking, described loading flange produces angular displacement with loading transfer panel; After reaching prescribed torque, fix loading bolt with locking nut, load flange and load transfer panel with clamping screw is fixing, thus the loading of realization 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 screwed 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 two groups of symmetrical holes.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, easy to operate, the degree of accuracy is high, safe and reliable; Axial dimension is very little, test platform structure compactness, 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 advantage.
