Abstract
The utility model discloses a tangential belt tensioning wheel in the textile field. the tangential belt tensioning wheel comprises a metal inner bushing sleeved outside a rotating shaft through two bearings which are arranged up and down, a belt wheel is sleeved on the periphery of the metal inner bushing, the two bearings are connected through a casing pipe disposed therebetween, the casing pipe is sleeved on the rotating shaft, an inner stage is disposed in the middle part of the rotating shaft, a clamping spring is disposed on the upper part of the rotating shaft, the two bearings are mounted on the inner stage through the clamping spring, an eccentric shaft is connected on the bottom part of the rotating shaft, a blind hole is disposed in an axial direction of the top part of the rotating shaft, an oil hole communicated with the blind whole is disposed on the rotating shaft between the two bearings, and a through hole corresponding to the oil hole is disposed on the casing pipe. With arrangement of the blind hole and the oil hole on the rotating shaft and the through hole matched with the oil hole on the casing pipe, an lubricating oil can be conveniently fed into the bearings, so as to prolong the service life of the bearings and reduce manufacturing costs; and the tangential belt tensioning wheel provided by the utility model is applicable to composite twisters.
Description
Technical field
The utility model relates to a kind of Weaving device, particularly a kind of composite twisting machine.
Background technique
At present in textile industry, the kind of drive of cable twisted netting twine spindle mainly contains two types of tengential belt transmission and spindle band transmissions.Tengential belt driving type composite twisting machine, because spindle transmission employing is tengential belt tangential transmission mode, therefore, is just provided with a central belt tensioning wheel every one or two ingot positions, for adjusting the radially tension force of tengential belt, consistent to guarantee the rotating speed of each spindle.The central belt tensioning wheel using at present, what generally adopt is that machine cut processing mode is made, technical maturity, stable performance.But it is higher that deficiency is mainly manifested in power consumption, noise is larger, and cost is higher, is unfavorable for the energy-conservation of composite twisting machine complete machine and consumption reduction.Existing central belt tensioning wheel upper-end surface is exposed in the middle of working environment in addition, foreign material and dust enter wherein and also can have a negative impact to it, and inner bearing is along with the growth of service time can cause bearing to lack lubricant oil, thereby affect the working life of bearing, and then the working life of shortening Idle wheel, increase manufacture cost.
Model utility content
The purpose of this utility model is to provide a kind of central belt tensioning wheel, and the wearing and tearing of having avoided bearing to cause because lacking lubricant oil in the working life of prolongation bearing, reduce manufacture cost.
The purpose of this utility model is achieved in that a kind of central belt tensioning wheel, comprise that the two bearings through distributing is up and down set in the metal inner lining cover in rotating shaft outside, described metal inner lining cover periphery is arranged with belt wheel, between two bearings, through sleeve pipe, be connected, described casing pipe sleeve is located in rotating shaft, described rotating shaft middle part is provided with interior step, described rotating shaft top arranges jump ring, two bearings is arranged on interior step through jump ring, described rotating shaft bottom is connected with eccentric shaft, described rotating shaft top axle is to offering blind hole, on shaft part in described rotating shaft between two bearings, offer the oilhole being connected with described blind hole, on described sleeve pipe, offer the through hole corresponding with described oilhole.
In the utility model when work,, if the lubricant oil in bearing reduces, can add lubricant oil to the blind hole at rotating shaft top, lubricant oil can from blind hole together with oilhole and through hole enter in bearing, bearing is lubricated.To being than, the beneficial effects of the utility model, the utility model is offered blind hole by the top in rotating shaft with prior art, and coordinate and to offer oilhole and through hole, make in bearing, to inject lubricant oil, convenient to operation, extend the working life of bearing, and reduced cost of production.The utility model can be used in composite twisting machine.
In order to strengthen sealability of the present utility model, described belt wheel top and bottom are all offered and are equipped with interior step, between described two interior steps, offer a plurality of poling tapped holes, described belt wheel top is installed with top cover through screw, and described belt wheel bottom is installed with bottom through screw.By being installed, top cover and bottom guarantee the reliability of the utility model work.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 belt wheel, 2 top covers, 3a, 3b bearing, 4 jump rings, 5 rotating shafts, 5a blind hole, 5b oilhole, 6 sleeve pipes, 6a through hole, 7 tapped holes, 8 bottoms, 9 eccentric shafts, 10 metal inner lining covers.
Embodiment
A kind of central belt tensioning wheel as shown in Figure 1, comprise the two bearings 3a distributing through up and down, 3b is set in the metal inner lining cover 10 in rotating shaft 5 outsides, metal inner lining overlaps 10 peripheries and is arranged with belt wheel 1, two bearings 3a, between 3b, through sleeve pipe 6, be connected, sleeve pipe 6 is set in rotating shaft 5, rotating shaft 5 middle parts are provided with interior step, rotating shaft 5 tops arrange jump ring 4, two bearings 3a, 3b is arranged on interior step through jump ring 4, rotating shaft 5 bottoms are connected with eccentric shaft 9, rotating shaft 5 top axle are to offering blind hole 5a, two bearings 3a in rotating shaft 5, on shaft part between 3b, offer the oilhole 5b being connected with blind hole 5a, on sleeve pipe 6, offer the through hole 6a corresponding with oilhole 5b, belt wheel 1 top and bottom are all offered and are equipped with interior step, between two interior steps, offer a plurality of poling tapped holes 7, belt wheel 1 top is installed with top cover 2 through screw, belt wheel 1 bottom is installed with bottom 8 through screw.
The utility model is by the through hole 6a that offers blind hole 5a, oilhole 5b and offer oilhole 5b coupling in rotating shaft 5 on sleeve pipe 6, thereby make in bearing 3a, 3b, to inject lubricant oil easily, thereby extend the working life of bearing 3a, 3b, reduce manufacture cost.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technological scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characteristicss wherein, these replacements and distortion are all in protection domain of the present utility model.
