Although synchronous cog belt is reliable transmission in transmission mechanism, strong shock resistance, but because the tooth that is compounded on the driving-belt is very easily damaged in the transferring power process, generally be usually used in the drive apparatus of the higher constant speed of rotary speed precision requirement or small-power transmission, at present, this kind of drive is used for having than the increasing of large speed ratio, deceleration transmission system, the occasion of simultaneously concrete larger power output, for example be 1:4 at the reduction of speed ratio, and use in the NC vertical lathe of maximum machining diameter 2.5m, and be not reported.
The utility model content
The purpose of this utility model is: the above-mentioned series of problems for feed box commonly used in the horizontal feed device of the NC vertical lathe of maximum machining diameter 2.5m-T-shaped leading screw or ZF decelerator exist provides a kind of new horizontal feed device.
The purpose of this utility model is achieved in that the horizontal feed device of the NC vertical lathe of a kind of maximum machining diameter 2.5m, comprise crossbeam, the crossbeam end plate, servomotor and leading screw, the crossbeam end plate is installed on the crossbeam end face, servomotor and leading screw are installed on the homonymy crossbeam end plate, it is characterized in that: the crossbeam end plate is provided with roll adjustment slide and axle sleeve, servomotor is fixedly mounted on the crossbeam end plate by the roll adjustment slide, leading screw is installed in the axle sleeve by bearing, the profile of tooth driven pulley is fixedly mounted on the end of leading screw, servomotor and cogged belt wheel are fixedly linked, reduction of speed between cogged belt wheel and the profile of tooth driven pulley is than being 1:4, centre-to-centre spacing is 400 ~ 420mm, the cogged belt wheel passes through the synchronous cog belt synchronization links with the profile of tooth driven pulley, has 7 intermeshing teeth at least in the cornerite zone that forms between synchronous cog belt and the cogged belt wheel.
In the utility model, described bearing is combination bearing.
In the utility model, sealing ring is installed in described combination bearing outer ring.
In the utility model, described servomotor is fixedly mounted on the crossbeam end plate by the roll adjustment slide and refers to: after servomotor and roll adjustment slide are fixing, adjust motor shaft and leading screw centre-to-centre spacing by stretching screw first, be fixed on the crossbeam end plate by the position of lock-screw with the roll adjustment slide again.
In the utility model, on the crossbeam end plate protective cover is installed, described protective cover covers in synchronous cog belt wherein.
The utility model has the advantage of: owing to be by the synchronous cog belt synchronization links between the profile of tooth driven pulley of the cogged belt of servomotor wheel and leading screw, this kind of drive is not only simple in structure, easy to maintenance, noise is little, do not need to lubricate, use cost is relatively low, make servomotor be in best inertia matching state, especially have 7 intermeshing teeth at least in the cornerite zone that forms between synchronous cog belt and the cogged belt wheel, can make synchronous cog belt have enough bearing capacitys; Owing at the combination bearing place rotary seal ring is installed, can be prevented that lubricating oil from entering in the synchronous cog belt; Because servomotor is fixedly mounted on the crossbeam end plate by the roll adjustment slide, can regulate easily the spacing of profile of tooth driving pulley and the passive belt wheel of profile of tooth, change the tensile force of synchronous cog belt; Leading screw is installed in the axle sleeve by combination bearing, can so that whole leading screw unit has best axial push-pull rigidity under the installing space that allows, have farthest promoted positioning accuracy and the kinematic accuracy of knife rest.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the schematic diagram of the kind of drive of the utility model embodiment
Among the figure: 1, roll adjustment slide, 2, servomotor, 3, the cogged belt wheel, 4, crossbeam end plate, 5, the profile of tooth driven pulley, 6, leading screw, 7, combination bearing, 8, rotary seal ring, 9, axle sleeve, 10, protective cover, 11, crossbeam, 12, screw, 13, synchronous cog belt, 14, lock-screw, 15, stretching screw.
The specific embodiment
Accompanying drawing discloses the concrete structure of the utility model embodiment without limitation, below in conjunction with accompanying drawing the utility model is done to describe further
By Fig. 1,2 as seen, the synchronous belt transmission device that the utility model comprises crossbeam 11, crossbeam end plate 4, servomotor 2, is comprised of cogged belt wheel 3, passive belt wheel 5 and synchronous cog belt 13, the major parts such as leading screw 6 composition.Described crossbeam end plate 4 is fixed on crossbeam 11 ends by screw 12, and servomotor 2 is installed on the roll adjustment slide 1; After servomotor 2 was fixed with roll adjustment slide 1, roll adjustment slide 1 was adjusted motor shaft and leading screw centre-to-centre spacing by stretching screw 15 first, by lock-screw 14 its position is fixed on the crossbeam end plate 4 again; Leading screw 6, combination bearing 7, rotary seal ring 8 are fixed on the crossbeam end plate 4 by axle sleeve 9; Profile of tooth driven pulley 5 is connected and installed by key and is fixed on leading screw 6 one ends; Cogged belt wheel 3 is fixed on the motor shaft of servomotor 2; With synchronous cog belt 13 synchronization links, form driving-chain between cogged belt wheel 3 and the profile of tooth driven pulley 5; Protective cover 10 covers in crossbeam end plate 4 and synchronous belt wheel device wherein fully, reaches dustproof, grease proofing effect.
Because the horizontal feed device at NC vertical lathe is to adopt deceleration transmission, the diameter of cogged belt wheel 3 is less than profile of tooth driven pulley 5, in order to guarantee that synchronous cog belt 13 has enough bearing capacitys in the process of transferring power, in design, must satisfy: when cogged belt wheel 3 passes through synchronous cog belt 13 synchronization links with profile of tooth driven pulley 5, have 7 intermeshing teeth at least in the cornerite zone that forms between synchronous cog belt 13 and the cogged belt wheel 3, jointly share the power of cogged belt wheel 3 by them, then drive profile of tooth driven pulley 5.In the present embodiment, the reduction of speed between cogged belt wheel 3 and the profile of tooth driven pulley 5 is than being 1:4, and centre-to-centre spacing is 410mm, in the cornerite zone that forms between synchronous cog belt 13 and the cogged belt wheel 38 intermeshing teeth is arranged.
