Description
Technical field
The present invention relates to a kind of servo digital control machine tool sliding table gear assembly, belongs to modular unit for modular machine technology neck
Domain.
Servo digital control technology often applies to building-block machine field, the servo motor of general servo NC mechanical slide unit
It is usually to be connected by shaft coupling with lead screw, that is to say, that it is 1 ︰ 1 that servo motor, which exports revolving speed and the rotating ratio of lead screw input speed,
Torque than also be 1 ︰ 1, such as the biggish centripetal force of practical need of work, then need the biggish servo motor of corresponding configuration, increase through
Ji expense.
The object of the present invention is to provide a kind of servo digital control machine tool sliding table gear assemblies, solve existing servo digital control group
Close in lathe and be connected because of servo motor and lead screw through shaft coupling, be 1 ︰ 1 there are rotating ratio and torque ratio, to have it is biggish into
To power, then the deficiency of the biggish servo motor of corresponding configuration is needed, realizes improve output torque through the invention, improve centripetal force,
The gap between transmission gear is overcome simultaneously.
The purpose of the present invention is what is be achieved through the following technical solutions, a kind of servo digital control machine tool sliding table loading drive gear
It sets, including servo motor and lead screw, characterized in that the servo motor is fixed on the transition cabinet of setting, servo motor
Axis on fixation be placed in the intracorporal compound driving gear of transition case, compound driving gear is by driving gear and driving tooth wheel set structure
At driving gear and driving tooth wheel set engage the driven gear for being nested with and being fixed on lead screw one end jointly, and driving tooth wheel set is nested with master
On the ladder outer diameter of moving gear；The inner surface of driving gear and driven gear is respectively provided with expansion sleeve, and expansion sleeve is through the bolt that is screwed on
Gland with cylindrical body squeezes.
Several kidney slots are arranged in the end of driving gear in the compound driving gear, and bolt is through driving gear kidney slot
It is connected and fixed with driving tooth wheel set.
The rotating ratio of the compound driving gear and driven gear is 1 ︰ 2.
The present invention changes the structure that servo motor and lead screw are connected through shaft coupling in existing servo digital control building-block machine, by watching
Taking motor and pass through, there is a pair of of gear of different rotating speeds to connect with lead screw, to realize raising output torque, improve centripetal force
Purpose changes driving gear and driving gear by adjusting the position of driving gear and driving tooth wheel set in compound driving gear
Secondary transverse tooth thickness, then common engagement driven gear realize forward and reverse gapless, pass through driving gear and driven gear and respective axis
Expansion sleeve is set and realizes seamless connectivity, the configuration of the present invention is simple has very strong practicability.
Fig. 1 is schematic view of the front view of the present invention；
Fig. 2 is the compound driving gear part enlarged structure schematic diagram in Fig. 1；
Fig. 3 is the left view structural representation of Fig. 2；
In figure, 1 servo motor, 2 driving gears, 3 driven gears, 4 transition cabinets, 5 lead screws, 6 glands, 7 bolts, 8 kidney slots, 9
Driving tooth wheel set, 10 expansion sleeves, 11 bolts.
The present invention is further illustrated in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the present invention is by servo motor 1, compound active
Gear, driven gear 3, transition cabinet 4, lead screw 5 are constituted.Servo motor 1 is installed on transition cabinet 4, compound driving gear peace
On axis loaded on servo motor 1, compound driving gear is made of driving gear 2 and driving tooth wheel set 9, driving gear 2 and active
Engagement is nested with the driven gear 3 for being fixed on 5 one end of lead screw to gear pair 9 jointly, and driving tooth wheel set 9 is nested with outside the ladder of driving gear
It is fixed through bolt 7 on diameter, the position of driving gear 2 and driving tooth wheel set 9 is adjusted, driving gear 2 and driving tooth wheel set 9 are changed
It realizes that positive and negative direction gapless couples with driven gear 3 after transverse tooth thickness, meets servo digital control requirement.Compound driving gear with it is driven
The speed ratio of gear 3 generally uses 1 ︰ 2.
As shown in figure 3, several kidney slots 8 are arranged in the end of the driving gear 2 in compound driving gear, bolt is through driving tooth
The kidney slot 8 of wheel 2 is connected and fixed with driving tooth wheel set 9.
As shown in Figure 1, 2, the inner surface of driving gear 2 and driven gear 3 is respectively provided with expansion sleeve 10, and expansion sleeve 10 is through being screwed on
The gland 6 with cylindrical body of bolt 11 squeezes.The expansion sleeve that driving gear 2 and driven gear 3 and respective axis pass through setting
Realize seamless connectivity.
