Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, of the present utility model a kind of can the rotary stand of arbitrarily angled stall, mainly comprise pedestal 16, be arranged on two suspension bearings 15 of the inner both sides of pedestal 16 respectively, be arranged on the main shaft 7 of suspension bearing inside, be arranged on the stall mechanism 17 on main shaft 7 by connector 8, main shaft 7 can be controlled by connector 8 and lock with stall mechanism 17 or depart from.Between stall mechanism 17 and main shaft 7, also fixed mechanism is provided with main shaft bearing 9.17, this stall mechanism, through the inner ring of two suspension bearings 15, makes itself and pedestal 16 fix.
In order to can be good at realizing the utility model, as shown in Figure 2, this stall mechanism 17 comprises worm screw supporting seat 4, be arranged on two worm bearings 3 of the inner both sides of worm screw supporting seat 4 respectively, through two worm bearing 3 endoporus be arranged in worm screw supporting seat 4 worm screw 1, this worm screw 1 can be rotated by two worm bearings 3.Worm screw 1 is also connected with handwheel 6, and this handwheel 6 is arranged on the outside of worm screw supporting seat 4, and is also provided with inclinometer 5 between worm screw supporting seat 4 and handwheel 6.When the external world rotates handwheel 6, inclinometer 5 can show the rotational angle of handwheel 6, is convenient for people to read.In addition, this stall mechanism 17 also includes turbine 2, and this turbine 2 and worm screw 1 adopt secondary design to be connected, and namely turbine 2 is engaged mutually with the teeth on worm screw 1, and turbine 2 then can be driven when worm screw 1 is rotated to rotate.This turbine 2 is fixed in pedestal 16 through two suspension bearings 15.
Meanwhile, 7, main shaft through turbine 2 endoporus and the one end of stretching out pedestal 16 clamped by connector 8, convenient like this adjustment connector 8.Turbine 2 and main shaft 7 can be made to lock or depart from when regulating connector 8.Between turbine 2 and main shaft 7, be also provided with two main shaft bearings 9, this main shaft bearing 9 is fixed by fixed mechanism and is sealed in turbine 2, and this main shaft bearing 9 can play the effect of supports main shaft 7.
In order to can be good at fixed main shaft bearing 9, this fixed mechanism is by the inner spacing collar 11 be arranged on main shaft 7, be arranged on the outer separator 10 outside this inner spacing collar 11, be arranged on the lining 13 for preventing inner spacing collar 11 from sliding on main shaft 7, be arranged on the main shaft back-up ring 12 for preventing main shaft 7 from sliding on lining 13, and be arranged on outside pedestal 16 and form for the set nut of Locking bushing 13.
During work, as long as locking connector 8 uses main shaft 7 and turbine 2 to lock and is integrated, rotate handwheel 6 again, worm screw 1 is rotated by main shaft bearing 3 and drives turbine 2 simultaneously, at this moment lock because of main shaft 7 and turbine 2 and be integrated, therefore main shaft 7 also follows turbine 2 to rotate, and the rotational angle of inclinometer 5 display simultaneously, can realize locked rotor test like this.When unclamping connector 8, turbine 2 and main shaft 7 depart from, and at this moment main shaft 7 is not by any impact from handwheel 6 revolving force, can realize main shaft 7 like this from active product to the conversion of driven product.
As mentioned above, just well the utility model can be implemented.
