Abstract
The utility model relates to a driving device for driving cable conductor traction disks in cable production, which solves the technical problem that the driving mechanism provided should be capable of preventing conductors from damages during traction and be simple in structure, accurate in transmission ratio and high in transmission torque. The technical scheme includes that the cable conductor traction device comprises a traction disk and a traction mechanism composed of a reduction box and a motor, and is characterized in that the reduction box and the traction disk are in transmission by the aid of a synchronous belt, the reduction box is a reduction gearbox, and the transmission ratio of a synchronous wheel to the reduction box is 1:1.
Description
Technical field
The utility model relates to a kind of power set, is specifically related to be used in a kind of cable production the drive unit of drive cable conductor sheave.
Background technology
During cable is produced,, when producing, tend to dispose a sheave it is drawn because the conductor 1 (being generally copper, aluminium) of cable is heavier.At present the driving mechanism of sheave is generally a gear reduction box 3 that disposes motor 2, adopts positive drive (as shown in Figure 2, gear reduction box directly drives the sheave rotation) between gear reduction box and the sheave 4.The advantage of this type of transmission is that driving torque is big, transmission speed ratio control is more accurate, reliable working performance, long service life.But through in a few years finding in the production process, adopt after the positive drive control, conductor through the sheave traction after, conductor is not stretching fully or when with the unwrapping wire place shake being arranged, it can not eliminate the influence between them fully, may cause the conductor damage sometimes.Find during detection that the echo index of cable obviously has a peak value about 1050MHZ and 2010MHZ, technical indicator is not up to standard, and product quality remains to be improved.
The utility model content
The purpose of this utility model is to overcome the deficiency that the above-mentioned background technology exists, a kind of improvement of driving mechanism of cable conductors sheave is provided, this driving mechanism should be able to prevent conductor in distraction procedure damage and also have characteristics simple in structure, that gearratio is accurate, driving torque is big.
The utility model proposes following technical scheme:
A kind of cable conductors draw-gear comprises sheave and the haulage gear of being made up of reduction box and motor, it is characterized in that: adopt band transmission synchronously between described reduction box and the sheave.
Described reduction box is a gear reduction box.
Gearratio between described synchronizing wheel and the reduction box is 1: 1.
The beneficial effects of the utility model are: in the utility model, gearratio between synchronizing wheel and the reduction box is 1: 1, adopting synchronously between the two, band carries out flexible transmission (Fig. 2), driving force does not change apart from basic, does not have Elastic Sliding and skids, can keep accurately gearratio, required tensile force pressure less, that act on axle little yet.And when changing in conductor motion, it is self-control within the specific limits, and after testing, the echo index is up to standard, and two place's indexs do not have tangible peak value substantially.In addition, the utility model is simple in structure, realizes easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of existing driving mechanism.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
Cable conductors draw-gear shown in Figure 2 comprises sheave 4 and haulage gear, and this haulage gear is made up of reduction box 3 and motor 2; Be separately installed with synchronizing wheel 6 on the rotation axis of sheave 4 and the gear reduction box output shaft, by two synchronizing wheels with synchronously with 5 engagement, realized the transmission between reduction box and the sheave.
The diameter of described synchronizing wheel is determined (the recommendation diameter is 180mm) as required, and the gearratio between synchronizing wheel and the reduction box is 1: 1.
Described gear reduction box, motor, be with equal buyable to obtain synchronously.
Claims (2)
1. a cable conductors draw-gear comprises sheave (4) and the haulage gear of being made up of reduction box (3) and motor (2), it is characterized in that: adopt band (5) transmission synchronously between described reduction box and the sheave.
2. a kind of cable conductors draw-gear according to claim 1 is characterized in that: described reduction box (3) is a gear reduction box.
