Description
Technical field
The present invention relates to a kind of machine tool sliding table gear drive, belongs to lathe universal component technical field.
Background technology
Servo digital control technology often applies to building-block machine field, the servomotor of general servo NC mechanical slide unit
It is typically to be connected by shaft coupling with leading screw, that is to say, that the rotating ratio of servomotor output speed and leading screw input speed is 1 ︰ 1,
Torque is 1 ︰ 1 than also, such as the larger centripetal force of actual need of work, then need the larger servomotor of corresponding configuration, add through
Ji expense.
The content of the invention
It is an object of the invention to provide a kind of machine tool sliding table gear drive, solves in existing servo digital control building-block machine
Because servomotor is connected with leading screw through shaft coupling, rotating ratio and torque ratio be present is 1 ︰ 1, to there is larger centripetal force, then
The deficiency of the larger servomotor of corresponding configuration is needed, is realized by the present invention and improves output torque, improved centripetal force, overcome simultaneously
Gap between travelling gear.
The purpose of the present invention is achieved through the following technical solutions, a kind of machine tool sliding table gear drive, including is watched
Motor and leading screw are taken, it is characterized in that, described servomotor is fixed on the transition casing of setting, fixed on the axle of servomotor
The compound driving gear being placed in transition casing, compound driving gear are made up of driving gear and driving tooth wheel set, driving gear
Engaged jointly with driving tooth wheel set and be nested with the driven gear for being fixed on leading screw one end, driving gear secondary case puts the ladder of driving gear
On external diameter；The inner surface of driving gear and driven gear is respectively provided with expansion sleeve, and expansion sleeve has cylindrical body through the bolt that spins
Gland extrudes.
Some mounting holes of end set of driving gear in the compound driving gear, bolt is through driving gear mounting hole
It is connected 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 servomotor is connected with leading screw through shaft coupling in existing servo digital control building-block machine, by watching
Take motor to be connected with leading screw through a pair of gears with different rotating speeds, it is achieved thereby that improving output torque, improve centripetal force
Purpose, by adjusting the position of driving gear and driving tooth wheel set in compound driving gear, change driving gear and 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 axle
Expansion sleeve is set to realize seamless connectivity, the present invention is simple in construction, has very strong practicality.
Brief description of the drawings
Fig. 1 is main structure diagram of the present invention；
Fig. 2 is the compound driving gear part mplifying structure schematic diagram in Fig. 1；
Fig. 3 is Fig. 2 left view structural representation；
In figure, 1 servomotor, 2 driving gears, 3 driven gears, 4 transition casings, 5 leading screws, 6 glands, 7 bolts, 8 mounting holes, 9
Driving tooth wheel set, 10 expansion sleeves, 11 bolts.
Embodiment
The present invention is further illustrated in conjunction with the accompanying drawings and embodiments, as shown in figure 1, the present invention is by servomotor 1, compound active
Gear, driven gear 3, transition casing 4, leading screw 5 are formed.Servomotor 1 is installed on transition casing 4, compound driving gear peace
On axle loaded on servomotor 1, compound driving gear is made up 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 the one end of leading screw 5 to gear pair 9 jointly, and driving tooth wheel set 9 is nested with outside the ladder of driving gear
Fixed on footpath through bolt 7, adjust the position of driving gear 2 and driving tooth wheel set 9, change driving gear 2 and driving tooth wheel set 9
Realize that positive and negative direction gapless couples with driven gear 3 after transverse tooth thickness, meet servo digital control requirement.Compound driving gear with it is driven
The speed of gear 3 than typically uses 1 ︰ 2,
As shown in figure 3, some mounting holes 8 of the end set of the driving gear 2 in compound driving gear, bolt is through driving gear 2
Mounting hole 8 be connected 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 spinning
The gland 6 with cylindrical body of bolt 11 extrudes.The expansion sleeve that driving gear 2 passes through setting with driven gear 3 with respective axle
Realize seamless connectivity.
