Abstract
The utility model discloses a drive mechanism that takes of pretightning force balances comprises belt drive part, tensioning part, balanced pretightning force part and base, motor, ball. The tensioning is realized by the tensioning part to this belt drive part, and balanced pretightning force part bears the pretightning force. The utility model has the advantages of compact, the convenient loading and unloading of simple structure, the belt pretightning force can be balance, parts such as main shaft in the pulley drive precision optical machinery, ball can be directly used.
Description
Technical field
The utility model belongs to precision mechanical transmission technical field, specifically refers to a kind of tape handler balancing pretightening force.
Background technique
V belt translation is a kind of important mechanical transmission, and the suction that has that structure is simple, stable drive is eased up such as to be shaken at the feature.But after operation a period of time, due to plastic deformation and wearing and tearing, belt can relax, the normal use of influence zone driving mechanism.Therefore tensioning mechanism is needed to realize belt tension in V belt translation.
Because the existence of tension force, belt wheel produces radial force to axle.And the vital part such as main shaft, ball screw in precision optical machinery, being subject to radial force can cause precision to reduce, and shortens the working life of vital part, even makes it directly damage, therefore should not directly use V belt translation mode.
Summary of the invention
Be directed to the Problems existing of above-mentioned background technology, the purpose of this utility model is to provide a kind of tape handler balancing pretightening force, have that structure is simple, the advantage of convenient assembling and disassembling, belt pretightening force can be balanced, directly can use the part such as main shaft, ball screw in belt wheel transmission precision optical machinery.
For achieving the above object, a kind of tape handler balancing pretightening force of the present utility model, comprise: V belt translation parts, tension part, balance pretightening force parts, base, motor and ball screw, V belt translation parts comprise large belt wheel, small pulley and band, large belt wheel is connected by being with small pulley, small pulley is arranged on the axle of motor, and large belt wheel is connected with ball screw; Tension part comprises motor flange and tensioning plate, and motor flange and motor are together fixed in the waist hole that above-mentioned base is provided with, and tensioning plate is provided with the adjustment hole of adjusting screw screw-in length; Balance pretightening force parts comprise band wheel seat, belt wheel fixed cover, bearing fixed cover, two deep groove ball bearings, band wheel seat is fixed by screws on base, two deep groove ball bearings are arranged between large belt wheel and band wheel seat, fix respectively by belt wheel fixed cover and bearing fixed cover.
Preferably, above-mentioned large belt wheel inner hole is processed with spline, is connected with ball screw by spline.
The tape handler of balance pretightening force of the present utility model, the tension force of large belt wheel bears by being with wheel seat and deep groove ball bearing, and ball screw does not bear pretightening force; Screw simultaneously by regulating tensioning plate to be provided with, changes screw screw-in length, regulates the distance of motor flange and tensioning plate, and then realize tensioning.
The beneficial effects of the utility model:
1. V belt translation ball screw be can use, ball screw precision and life-span do not affected;
2. simple and compact for structure, easy disassembly, reliability is strong.
Accompanying drawing explanation
Fig. 1 illustrates the structural representation of the tape handler of the utility model balance pretightening force.
Fig. 2 illustrates the structural representation of base in the utility model.
Embodiment
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that mode of execution is mentioned is not to restriction of the present utility model.
Shown in Fig. 2, a kind of tape handler balancing pretightening force of the present utility model, comprise: V belt translation parts, tension part, balance pretightening force parts, base 1, motor 2 and ball screw 3, V belt translation parts comprise large belt wheel 41, small pulley 42 and band 43, large belt wheel 41 is connected by band 43 with small pulley 42, small pulley 42 is arranged on the axle of motor 2, and large belt wheel 42 is connected with ball screw 3; Tension part comprises motor flange 51 and tensioning plate 52, and motor flange 51 and motor 2 are together fixed in the waist hole 11 that above-mentioned base 1 is provided with, and tensioning plate 52 is provided with the adjustment hole of adjusting screw 53 screw-in length; Balance pretightening force parts comprise band wheel seat 61, belt wheel fixed cover 62, bearing fixed cover 63, two deep groove ball bearings 64, band wheel seat 61 is fixed by screws on base 1, two deep groove ball bearings 64 are arranged between large belt wheel 41 and band wheel seat 61, fix respectively by belt wheel fixed cover 62 and bearing fixed cover 63.
In described V belt translation parts, small pulley 42 is arranged on the axle of motor 2, is fixed by screw and lock washer, large belt wheel 41 endoporus is processed with spline, be connected with ball screw 3, and be also processed with annular groove 411 in large belt wheel 41, place above-mentioned balance pretightening force parts by it; In addition, large belt wheel 41 is also provided with screw, conveniently removes bearing by screw.
In described tension part, motor flange 51 and motor 2 are together fixed on above-mentioned base 1, tensioning plate 52 is fixed by screws on base 1, tensioning plate 52 is processed with the adjustment hole of screw 53 screw-in length, to install adjusting screw 53, by changing the screw-in length of adjusting screw 53, pushing motor flange 51 slides in waist hole 11, and then regulate the distance of motor flange 51 and tensioning plate 52, and then realize tensioning.
In described balance pretightening force parts, band wheel seat 61 and two deep groove ball bearings 64 are located between ball screw 3 and large belt wheel 41, bear the tension force that large belt wheel 41 produces, reduce the pretightening force that ball screw 3 bears.
The utility model embody rule approach is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
