Description
Technical field
The utility model belongs to hardware & tools, particularly the large power screwdriver of one.
Background technology
At present, in power industry large scale electrical power unit is installed, the instrument needed also correspondingly will improve power, if the screwdriver of holding screw, common screwdriver one is that power is inadequate, and screwdriver common in addition can not be had an effect in use continuously, speed that is fastening and dismounting screw is slow, make the efficiency of production low, especially to special operating mode and the dead screw that become rusty for a long time, normal screws cutter is just more inadaptable.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of bearing capacity large, can power continuously, tackles the large power screwdriver of complex working condition.
The technical scheme that the utility model technical solution problem adopts is: large power screwdriver comprises housing, worm screw, worm gear, worm set, worm screw handle, active umbrella gear shaft, driven bevel pinion axle, driving bevel gear, driven bevel pinion, be characterized in the center chassis place dress sliding bearing one in discoidal housing, at sliding bearing one built with active umbrella gear shaft, driving bevel gear is filled below at the periphery flat key of sliding bearing one, worm gear is housed above, the outer circle wall of housing installs worm screw, one end and the worm gear of worm screw are connected by meshing transmission, the other end of worm screw is provided with worm screw handle, and be screwed worm set in worm screw periphery, with the housing wall of worm screw vertical direction on fill driven bevel pinion axle with sliding bearing two, and at housing inner-outer sleeve, inner splint and external splint are housed, inner splint and external splint bolt connect, driven bevel pinion and driving bevel gear are connected by meshing transmission, the external end head of driven bevel pinion axle is equipped with driver bit with spline.
The beneficial effects of the utility model are: large power screwdriver is by changing transmission direction, and bearing capacity is large, can adapt to the installation and removal of different model and different operating mode screw, especially can dismantle and install and the dead screw that becomes rusty for a long time, increase work efficiency, time saving and energy saving.
