Problems solved by technology

The advantage of these two loading methods is that the torque can be adjusted in real time, but there are also disadvantages
The axial dimension of the loader itself is long, resulting in a large span of the shaft system of the entire test bench, and the speed of the test bench cannot be increased
The cost of hydraulic torque loader and electric torque loader is very high, and there are no mature manufacturers in China at present

Embodiment Construction

[0015] Below the present invention will be further described in conjunction with accompanying drawing:

[0016] Such as Figure 1-Figure 2 As shown, it includes loading bolt 1, locking nut 2, locking bolt 3, self-locking nut 4, loading flange 5 and loading adapter plate 6.

[0017] The loading flange 5 is provided with two centrally symmetrical loading threaded holes; the loading flange 5 is provided with two groups of symmetrical arc grooves, each group of three grooves; the loading bolt 1 is connected from the loading flange 5 Tighten in the threaded hole, and put it on the loading adapter plate 6. The loading adapter plate 6 is provided with two groups of symmetrical holes, each group of three holes corresponds to the loading flange one by one; the loading flange 5 is nested with the loading adapter plate 6; locked with the lock nut 2, the loading flange 5 and the load adapter plate 6 produce an angular displacement, and the torque is observed through the torque sensor, an...

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 [0001] The invention relates to a torque loading mechanism, which is used for applying a required test torque to a dynamic closed power test bed. After the specified torque is reached, the whole test bed can carry out a dynamic rotation test. Background technique [0002] The dynamic enclosed power test bench generally uses a hydraulic torque loader or an electric torque loader to apply torque to the entire enclosed shafting. The advantage of these two loading methods is that the torque can be adjusted in real time, but there are also disadvantages. The axial dimension of the loader itself is long, resulting in a large span of the shaft system of the entire test bench, and the speed of the test bench cannot be increased. The cost of hydraulic torque loader and electric torque loader is very high, and there are no mature manufacturers in China at present. Contents of the invention [0003] The object of the present invention is to overcome the above disadv...
