Abstract
The invention discloses a novel belt pulley device, which consists of a belt pulley, a fixing sleeve, a conical tensioning shaft sleeve and connecting screws. The design principle of the belt pulley device adopts a drawing-back mode; after the fixing sleeve and the belt pulley and the fixing sleeve and the conical tensioning shaft sleeve are primarily fixed, a motor shaft extends into the conical tensioning shaft sleeve, six connecting screws are symmetrically and uniformly screwed, and the fixing sleeve gradually expands to be more and more tightly contacted with an inner hole of the belt pulley under the forward pretightened pressure of the conical tensioning shaft sleeve due to the influence of the drawing-back design of the conical tensioning shaft sleeve; likewise, the conical tensioning shaft sleeve shrinks to be more and more tightly contacted with the motor shaft when pretightened into the fixing sleeve. When the conical tensioning shaft sleeve is completely connected with the fixing sleeve under the action of the connecting screws, the connections between the belt pulley and the fixing sleeve, between the fixing sleeve and the conical tensioning shaft sleeve and between the conical tensioning shaft sleeve and the motor shaft are in the tightest state. The novel belt pulley device is novel in design and reliable in connecting firmness.
Description
(1) technical field
The present invention relates to the Rapier looms field, be specifically related to a kind of motor belt wheel apparatus that is applied in the high speed rapier loom main shaft transmission device.
(2) background technology
Rapier looms is the textile machine in a kind of industry that is widely used in weaving cotton cloth, range of application and field are all boundless in China's textile industry, closely during the last ten years, along with China loom manufacturing firm constantly carries out technological innovation to Rapier looms, the performance of Rapier looms is greatly improved at present, and the speed of mainshaft of Rapier looms has generally been brought up to more than per minute 180 commentaries on classics.In this case, loom is had higher requirement to each parts of transmission system.Pulley apparatus for the loom main driving motor, traditional assembling mode all adopts belt pulley endoporus and motor shaft to carry out the key location, though this mode can satisfy fixedly needs, but owing to need belt pulley and motor shaft are carried out the preprocessing of keyway, the technology relative complex, the generation that easily brings substandard products spare and discard; Secondly because the keyway of belt pulley and motor shaft in long-term frequent start-stop process, easily produces wearing and tearing and becomes flexible, wearing and tearing reach a certain amount of after, just must change belt pulley and motor shaft, maintenance cost is relatively large; At last, because the needs of this kind fixed form, motor shaft need keep certain length, so that belt pulley endoporus and motor shaft carry out best location, makes motor shaft its corresponding torque when starting reduce like this, and the starting time of complete machine seems long.And Rapier looms is the quite frequent equipment of a kind of intermittence startup-shutdown, and above-mentioned drawback is given the influence that all has in the normal operation of loom and the cost control to a certain degree.
(3) summary of the invention
The present invention mainly provides the pulley apparatus in a kind of spindle gearing that is applied on the machinery such as Rapier looms, and main technical schemes is as follows:
A kind of novel pulley apparatus is made up of belt pulley, fixed cover, taper tensioner axle sleeve and connecting screw.The endoporus of belt pulley leaves slope angle at two ends, and slope angle stretches out, and forms an endoporus between the two hipped end angles, and interior hole length is the same with fixed cover length.
Described fixed cover has an expansion slot vertically, and fixed cover external diameter under normal conditions is slightly less than the belt pulley diameter of bore, with when assembling fixed cover can easily put into the belt pulley endoporus and be advisable.The end face of fixed cover one side is provided with six screw holes, is used for fixing with the connecting ring of taper tensioner axle sleeve.
Taper tensioner axle sleeve one side is provided with connecting ring, the face size of connecting ring is identical with the face size of fixed cover, connecting ring is provided with three groups of fixed screw holes, every group has three screw holes, it is corresponding with the screw hole of fixed cover end face that two screw holes on every group two limit are formed six screws altogether, and the moving back during as the dismounting pulley apparatus of three screw holes in the middle of every group of screw hole pulled out screw hole.
The axle sleeve of described taper tensioner axle sleeve is tapered to the other end from the connecting ring end, and the outside dimension of the conical nose diameter of bore with fixed cover under normal conditions is identical, and taper tensioner axle sleeve also is provided with an open slot.
Design principle of the present invention is for moving back the formula of pulling out, when assembling belt pulley on the driving motor axle, earlier fixed cover and belt pulley are positioned, again fixed cover and taper tension shaft being applied mechanically six hexagon socket head cap screws carries out tentatively fixing, after adjusting the position of motor shaft, motor shaft is stretched in the taper tensioner axle sleeve, balancedly symmetry is tightened six connecting screws then, when connecting screw is constantly tightened, taper tensioner axle sleeve is stressed constantly to move ahead in fixed cover, moved back by taper tensioner axle sleeve and pulls out the influence that formula designs, and fixed cover is under taper tensioner axle sleeve moves ahead the pressure that holds out against, gradually produce and expand, more and more tightr with contacting of belt pulley endoporus; Same principle, taper tensioner axle sleeve also is subjected to the opposition of fixed cover, produces shrinkage phenomenon when constantly holding out against in fixed cover, becomes more and more tightr with contacting of motor shaft.After being connected fully under taper tensioner axle sleeve and the effect of fixed cover in connecting screw, the state the most closely that just reached that is connected of belt pulley and fixed cover, fixed cover and taper tensioner axle sleeve, taper tensioner axle sleeve and motor shaft.
When this pulley apparatus of dismounting, unscrew six connecting screws earlier, again with three connecting screws moving back to pull out in the screw hole and tighten from the taper tension shaft cover connecting ring, after screw head holds out against the fixed cover end, taper tensioner axle sleeve is stressed to be withdrawed to nut end, with taper tensioner axle sleeve, taper tensioner axle sleeve and till contacting of motor shaft returns to normality fully, can easily separate each parts until belt pulley and fixed cover, fixed cover.
Novel pulley apparatus of the present invention, modern design, it is reliable to connect fastness, compares with traditional motor belt wheel apparatus, has following beneficial effect:
1, reduced manufacturing procedure, can avoid in the keyway process damage that belt pulley and motor shaft are brought, stopped phenomenon such as to scrap because of the part that keyway processing produces at belt pulley endoporus and the enterprising line unit groove of motor shaft.
2, this kind pulley apparatus fixed form can reduce the link length of motor shaft in design, can increase the output torque of motor shaft in the running because of the minimizing of motor shaft link length, help alleviating motor load and reduce the machinery equipment starting time, have remarkable energy saving effect.
3, each fixture of this kind pulley apparatus pulls out the formula design for moving back, and assembling and dismounting are very easy, can not produce any damage to motor shaft and belt pulley, so the part long service life, between the textile machine user operating period, can alleviate user's costs such as maintenance.
