Description
Technical field
The utility model relates to a kind of radial loading device of shaft element load test, belongs to shaft element load test technical field.
Background technology
Some shaft elements, in actual moving process, except being subject to the effect of rotary torque, are also subject to the effect of radial force.When carrying out load test to some shaft element, if only consider the effect of rotary torque, will the relatively large deviation of test findings be caused, and therefore corresponding radial load being applied to some shaft element and seeming very necessary.Mostly the existing charger for shaft element load test is to be loaded by single moment of torsion, and only has less elaboration to the test unit that radial load loads, and far can not meet the demand of shaft element load test to radial load charger.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of radial loading device of shaft element load test, to solve the problem can not carried out radial load loading and can not quantitatively load in shaft element load test.
The technical solution of the utility model is: a kind of radial loading device of shaft element load test, comprises worktable 1, hold-down support 2, loading bar 3, bearing (ball) cover I 5, bearing holder (housing, cover) 6, bearing 7, round nut 8, bearing (ball) cover II 9, force snesor 10, force bolt 11, bearing (ball) cover I 5, bearing (ball) cover II 9 is arranged on bearing holder (housing, cover) 6, bearing 7 is arranged on bearing (ball) cover I 5, between bearing (ball) cover II 9 and bearing holder (housing, cover) 6 in position, shaft element 4 is arranged in bearing 7, and by round nut 8 axial location shaft element 4 and bearing 7, hold-down support 2 is bolted and is arranged on worktable 1, force snesor 10 is arranged in hold-down support 2, force bolt 11 is threaded connection and is fixed on hold-down support 2 bottom, and be connected with bottom force snesor 10, loading bar 3 is arranged in hold-down support 2, and be connected with force snesor 10 top, loading bar 3 upper end is positioned at bottom bearing holder (housing, cover) 6.
Described force bolt 11 upper end is installed on boss I 12, and boss I 12 is positioned at the hole slot I 13 that force snesor 10 lower end is offered, and loading bar 3 lower end is installed on boss II 14, and boss II 14 is positioned at the hole slot II 15 that force snesor 10 upper end is offered.
Principle of work of the present utility model is: rotate force bolt 11 with spanner and make force bolt 11 move upward to realize the loading of load relative to hold-down support 2, load through force snesor 10, loading bar 3, bearing holder (housing, cover) 6 and bearing 7 sequence delivery on shaft element 4, realize loading the radial load of shaft element 4, and directly measure the concrete numerical value of loaded load by force snesor 10.
The utility model has following beneficial effect:
1, shaft element radial force situation can be simulated;
2, can the size of fixing quantity radial load;
3, structure is simple, volume is little, easy to operate, practical.
