Specific embodiment

The utility model is described further with reference to the accompanying drawing.

A kind of pitch motor dismounting tooling, as depicted in figs. 1 and 2, including top plate 1 and substrate 3, wherein top plate 1 is opposite sets It is placed in 3 top of substrate, the variable propeller gearbox ring flange 2 of connection variable propeller gearbox is provided between top plate 1 and substrate 3, substrate 3 passes through Bolt is fixed in the bottom surface of variable propeller gearbox ring flange 2, and top plate 1 is fixed in one by litter 4 and substrate 3, and right on substrate 3 Claim that the jackscrew 5 for jacking up top plate 1 is installed.

As shown in Fig. 2, substrate 3 includes short steel bar A31 and long steel bar A32, and installation jackscrew 5 is offered on short steel bar A31 Top wire hole 33, and offered on short steel bar A31 and long steel bar A32 and 2 upper screwed hole same size of variable propeller gearbox ring flange Mounting hole 34, short steel bar A31 and long steel bar A32 are connected in one by litter 4, by two mounting holes 34 of long steel bar A32 It is contrasted with the threaded hole on variable propeller gearbox ring flange 2, blending bolt passes through mounting hole 34 and threaded hole, so that long steel bar A32 and variable propeller gearbox ring flange 2 are fixed in one.

As shown in Figures 2 and 3, long steel bar A32 is placed in the lower section of short steel bar A31, and short steel bar B11 is contacted with short steel bar A31, Long steel bar B12 is placed in the top of short steel bar B11, then litter 4 is sequentially passed through long steel bar A32, short steel bar A31, short steel bar B11 and Long steel bar B12, i.e., so that short steel bar A31, short steel bar B11 and long steel bar B12 are slided along litter 4.

As shown in Figure 1 and Figure 4, variable propeller gearbox ring flange 2 is placed between long steel bar B12 and long steel bar A32, and variable pitch tooth The outer rim of roller box ring flange 2 is convenient for variable propeller gearbox ring flange 2 away from there is a distance with short steel bar A31, short steel bar B11 respectively It is mobile, so that the keyway 21 of the axle key of motor and variable propeller gearbox ring flange 2 is aligned.

On the basis of above scheme, the length of the litter 4 is 10cm or more.

On the basis of above scheme, long steel bar A32 and short steel bar A31 are respectively 2, long steel bar B12 and short steel bar B11 It also is respectively 2.
