Description
Technical field
The utility model relates to a kind of static strength proving installation, relates in particular to a kind of experimental provision for test express locomotive drive sleeve static strength.
Background technology
Along with the continuous speed-raising of China railways, locomotive running speed improves constantly, and firmly influence is also more and more obvious to the wheel track action for unsprung mass, therefore, reduces a technical barrier that must solve when unsprung mass has become the highspeed rail vehicle design.Adopt the locomotive of six connecting rod Hollow Shaft Transmission modes, half quality of drive sleeve belongs to unsprung mass, therefore can obviously reduce unsprung mass by the quality that reduces tubular shaft, improves the wheel track action firmly, improves the dynamic performance of locomotive.
But when reducing the drive sleeve quality, guarantee that its static strength becomes the problem that needs are paid close attention to.Therefore need a kind of experimental provision for the test static strength to test to alleviate the stress situation at each position of drive sleeve after the quality, propose improvement project on this basis, purpose is to prevent that working condition underdrive tubular shaft afterwards from defectives such as obvious crackle, deformation and failure taking place.
The utility model content
The utility model provides a kind of experimental provision for test express locomotive drive sleeve static strength, it can test the stress situation that alleviates each position of drive sleeve after the quality, propose improvement project on this basis, purpose is to prevent that working condition underdrive tubular shaft afterwards from defectives such as obvious crackle, deformation and failure taking place.
For reaching above purpose, the technical scheme that the utility model adopts is: a kind of experimental provision for test express locomotive drive sleeve static strength, it is characterized in that, it comprises worktable (1), supporting seat A(2), supporting seat B(3), reverse lever (4), lifting jack (5), pressure transducer (6), ess-strain sheet (7) is some, electric wire (8) is some: described supporting seat A(2) with supporting seat B(3) staggered relatively and all be fixed on the worktable (1), described lifting jack (5) places supporting seat B(3) the place ahead and being fixed on the worktable (1), its underpart links to each other with pressure transducer (6), described pressure transducer (6) links to each other with computing machine by electric wire (8), described lever (4) one ends that reverse contact with lifting jack (5) top, the other end is connected supporting seat B(3 by hinged connected mode) on, described ess-strain sheet (7) links to each other with computing machine by electric wire (8).
Described supporting seat A(2) by being bolted on the worktable (1).
Described supporting seat B(3) by being bolted on the worktable (1).
Described lifting jack (5) is by being bolted on the worktable (1).
The beneficial effects of the utility model: the utility model provides a kind of experimental provision for test express locomotive drive sleeve static strength, it can test the stress situation that alleviates each position of drive sleeve after the quality, propose improvement project on this basis, purpose is to prevent that working condition underdrive tubular shaft afterwards from defectives such as obvious crackle, deformation and failure taking place.

Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better; below in conjunction with accompanying drawing the utility model is described in detail; the description of this part only is exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.
As shown in Figure 1, a kind of experimental provision for test express locomotive drive sleeve static strength, it comprises worktable 1, supporting seat A2, supporting seat B3, reverses lever 4, lifting jack 5, pressure transducer 6, ess-strain sheet are 7 some, electric wire 8 is some.Supporting seat A2 and supporting seat B3 are staggered relatively and all by being bolted on the worktable 1, lifting jack 5 places supporting seat B3 the place ahead and by being bolted on the worktable 1, its underpart links to each other with pressure transducer 6, and described pressure transducer 6 links to each other with computing machine by electric wire 8.Reverse lever 4 one ends and contact with lifting jack 5 tops, the other end is connected on the supporting seat B3 by hinged connected mode.Ess-strain sheet 7 links to each other with computing machine by electric wire 8.
Referring to Fig. 1, Fig. 2, principle of work of the present utility model is: drive sleeve 9 is fixed on the utility model, namely an end is by being bolted on the bracing frame A2, and the other end is by being bolted to an end place of reversing lever 4 hinged with bracing frame B3, and to select this end be the force side.Ess-strain sheet 7 is sticked at key carrying position at drive sleeve 9, will reverse the distance of lever 4 jack-up by control lifting jack 5 and control the moment of torsion that imposes on drive sleeve 9, tests the stress situation at its crucial carrying position.Test is at first to beginning prestrain after each parameter zero clearing, treat that load is stable after, gather stress data immediately, unload and gather the unrelieved stress data then.After experiment finishes, check on drive sleeve 9 each position macroscopic views whether defectives such as obvious crackle, deformation and failure take place.And improvement project is proposed on this basis, purpose is to prevent that working condition underdrive tubular shaft 9 afterwards from defectives such as obvious crackle, deformation and failure taking place.
