Described driving axocoel two ends are provided with driving shaft end cap, the driving shaft being arranged in chamber uses bearing to be fixed on housing, and driving shaft front end is equipped with the bevel gear being connected with actuating unit, and axle shaft gear is housed on axle, driving shaft tail end is provided with the gland that is connecting adjusting bolt
Two described axocoel two ends are provided with two hubcaps, and two axles that are arranged in chamber use deep groove ball bearing to be fixed on housing, on the axle sleeve of two axles, duplicate gear are installed, and a gear of duplicate gear engages with axle shaft gear, and another engages with lead screw shaft gear,
Described leading screw axocoel front end is provided with leading screw axocoel drive end bearing bracket, rear end is provided with conical head, the lead screw shaft overcoat being arranged in chamber has leading screw axle sleeve, leading screw axle sleeve uses deep groove ball bearing and taper roll bearing to be fixed on housing, spline joint between lead screw shaft and leading screw axle sleeve, and lead screw shaft front end is connecting threading tool, rear end is leading screw, leading screw overcoat has mother lead screw, and lead screw shaft gear is housed in lead screw shaft, and lead screw shaft and conical head and drive end bearing bracket junction are equipped with O-ring seals.
The bearing of described fixed drive axle is the combination of deep groove ball bearing and taper roll bearing.
Described conical head is provided with mother lead screw positioner.
Power set in the utility model on tapping machine equipment drive bevel gear rotation, bevel gear drives driving shaft rotation, driving shaft is by gear driven two axle rotations, two axles are by the rotation of gear driven leading screw axle sleeve, leading screw axle sleeve drives lead screw shaft rotation by spline, and leading screw can drive lead screw shaft axial advancement because rotating the mother lead screw being fixed on housing simultaneously.In the time that bevel gear is rotated in the forward, lead screw shaft will be rotated while be advanced under the drive of bevel gear like this, and threading tool carries out tapping operation.As a same reason, in the time that bevel gear counter-rotates, lead screw shaft will be rotated while be retreated.
The beneficial effects of the utility model are to use the leading screw frame housing of sealing that each axle and transmission mechanism are all sealed in housing, in housing, fill lubricating oil, can make each parts move under the state of sufficient lubrication, reduce friction loss, keep the clean of each parts, not only can improve the precision of equipment but also increase the service life.
