The utility model content
The purpose of the present utility model: propose a kind of improved roller driving mechanism, it is the aluminium alloy wheel hub of heat-treating, when arriving the fire door outlet, fast roller will pick out wheel hub from roller at a slow speed, and can make that the wheel hub discharging is neat, thermosteresis is reduced to minimumly in the stove, requires roller just to change, can not reverse, can not skid, but also the wheel hub that rolls on is at a slow speed moved on the quick transmission roller rapidly.
The ratchet mechanism of this full-automatic continuous aluminum alloy wheel hub thermal treatment unit, comprise worm screw, drive rotating shaft, worm gear, lubricating cup, adapter sleeve, roller shell, roller, rotating shaft in the roller, connecting bushing, copper sheathing, split pin, bearing, lubricating cup, and some cover bearings, joint bolt, it is characterized in that: an end is provided with the driving rotating shaft of worm gear by split pin, and the adapter sleeve that connects through this split pin, be located at the connecting bushing in the adapter sleeve, rotating shaft is through the affixed composition endless screw-worm gear of joint bolt axle linkage driving structure in the roller, and the ratchet subassembly of being made up of ratchet and pawl is being set in the rotating shaft in roller, simultaneously again in described roller the shoulder at the two ends of rotating shaft respectively be provided with one group of bearing, the outer ring of this group bearing is provided with one and can freely rotates with bearing pack, and the outer ring has the roller shell of roller, constitutes the ratchet mechanism of the unidirectional rotation that is subjected to ratchet control thus.
The outer ring of the ratchet in the described ratchet subassembly is provided with and somely is connected ratchet on the roller shell through joint bolt.
The ratchet mechanism of this full-automatic continuous aluminum alloy wheel hub thermal treatment unit that proposes according to above technical scheme, by being arranged on the ratchet mechanism on the fire door exit microrunning roller, when the wheel hub operation will be come out of the stove, the motor-driven mechanism in exit drives the roller fast rotational, and this fashionable dress ratchet-wheel gear and rolled wheel hub on the roller at a slow speed and drive roller and also and then rotate towards a direction fast together.Because this ratchet-wheel gear can only can not reverse to a direction rotation, make the discharging of wheel hub operational process neat.Avoided that discharging is uneven to cause some flase operations to optoelectronic switch

Embodiment
As Fig. 1, the ratchet mechanism of this full-automatic continuous aluminum alloy wheel hub thermal treatment unit shown in 2, it is a kind of inventive improvements to the roller transmission rig of existing aluminium alloy wheel hub thermal treatment unit, the ratchet mechanism of this wheel hub thermal treatment unit, comprise worm screw 1, drive rotating shaft 2, worm gear 3, lubricating cup 5, adapter sleeve 6, roller shell 7, roller 12, rotating shaft 13 in the roller, connecting bushing 14, copper sheathing 16, split pin 17, bearing 19, lubricating cup 5, and some cover bearings, joint bolt, it is characterized in that: an end is provided with the driving rotating shaft 2 of worm gear 3 by split pin 17, and the adapter sleeve 6 that connects through this split pin, be located at the connecting bushing 14 in the adapter sleeve 6, rotating shaft 13 is through a joint bolt 15 affixed composition endless screw-worm gear axle linkage driving structures in the roller, and the ratchet subassembly of being made up of ratchet 20 and ratchet 19 is being set on the outer end axle of rotating shaft 13 in roller; Simultaneously again in described roller the shoulder at the two ends of rotating shaft 13 respectively be provided with one group of bearing 4, being provided with one can freely rotate and the outer ring has the roller shell 20 of roller with bearing pack 4 in the outer ring of this group bearing, constitutes the ratchet mechanism of the unidirectional rotation that is subjected to ratchet control thus.
The outer ring of the ratchet 20 in the described ratchet subassembly is provided with and somely is connected ratchet 19 on the roller shell through joint bolt 9.
The ratchet mechanism of this aluminium alloy wheel hub thermal treatment unit, its principle of work is as follows:
Unlatching along with drive-motor, worm screw 1 has passed to worm gear 3 with kinetic energy, so just making the driving rotating shaft 2 that is set in the turbine also rotates synchronously. because this driving rotating shaft 2 connects adapter sleeve 6 by split pin 17, and this adapter sleeve 6 is consolidated into one by the roller rotating shaft 13 of being located at joint bolt 15 on the body and will being arranged on the intravital connecting bushing 14 of cover and be positioned at this connecting bushing center. therefore just so far, make the interior rotating shaft 13 of rotation axis 2 and roller connect to form endless screw-worm gear axle linkage driving structure with the kinetic energy transmission of drive-motor; Simultaneously, rotating shaft 13 in the roller that is provided with in the technical program, on its axis body by one group of rolling bearing 4 being provided with and be nested with roller shell 7, roller 12 this group bearing outside, form a free rolling roller component that does not rely on interior rotating shaft 13 drivings of roller.
So when ratchet mechanism with this aluminium alloy wheel hub thermal treatment unit, the fire door outlet that is arranged on full-automatic continuous aluminum alloy wheel hub thermal treatment unit is picked on the roller of wheel hub, when the wheel hub operation will be come out of the stove, the motor-driven mechanism in exit drives the roller fast rotational, and the wheel hub that rolls at a slow speed on the roller that this fashionable dress ratchet-wheel gear drives roller also and then together fast towards a direction rotation.Because this ratchet-wheel gear can only can not reverse to a direction rotation, make the discharging of wheel hub operational process neat, reach and avoid the uneven purpose that causes some flase operations to optoelectronic switch of discharging.
