Description
The utility model relates to a kind of mechanical transmission pulley arrangement, is a kind of pulley arrangement of aligning the driving belt sideslip specifically.
Be in the transmission system of driving belt with synchronous cog belt or flat belt, because the driving belt that is enclosed within on the belt wheel is unrestricted at width direction, ubiquity driving belt sideslip problem.In system's running, in case the driving belt sideslip occurs, not only damage driving belt, but also can produce the transmission power deficiency.At present, both at home and abroad in this type of gearing of producing, most ofly corresponding levelling mechanism is not set, just adopts the belt wheel rib that the sideslip of driving belt is limited at the driving belt sideslip.Also have minority to adopt levelling mechanism, but it regulates complexity, the levelling scope is little, and effect is not satisfactory.
The purpose of this utility model be the design a kind of simple in structure, regulate easy to use, the pulley arrangement that the levelling driving belt that regulating effect is good is gone around.
The utility model is achieved in that a kind of pulley arrangement of aligning the driving belt sideslip, it comprises support, rack-mount axle and be installed in belt wheel on the axle by radial ball bearing and sleeve, the two ends of belt wheel are provided with rib, wherein, the two ends of said axle are supported by selfaligning ball bearing, and a selfaligning ball bearing is fixed in the mounting hole of support one end, and by the end cap axially locating; Another selfaligning ball bearing is installed in the hole of the support the other end by eccentric bushing, and making eccentric bushing and support mounting hole is that little gap is rotatably assorted.But eccentric bushing is pressed on the support by the briquetting of degree of tightness, and the eccentric bushing outer end is provided with end cap, the other end of axle by the dead axle bolt therewith end cap be located by connecting, on the cylindrical of eccentric bushing boss, be provided with the adjustment bolt of radial arrangement.
With the utility model as guiding belt wheel or tensioning pulley in synchronous cog belt or the flat belt transmission system, in the transmission system running, the rotating eccentricity cover, can make not the guiding belt wheel or the certain angle of tensioning pulley inclination of transmitted power, change the tightness of driving belt broad ways, realize levelling, and it is simple in structure driving belt, levelling is convenient, and is effective.
Now in conjunction with the accompanying drawings and embodiments the utility model is described specifically:
Fig. 1 is the utility model structural representation;
Fig. 2 is the worm's eye view of Fig. 1;
Fig. 3 is the eccentric bushing structural representation.
As depicted in figs. 1 and 2, a kind of pulley arrangement of aligning the driving belt sideslip, it comprises support 3, is installed in the axle 6 on the support 3 and is installed in belt wheel 5 on the axle 6 by radial ball bearing and sleeve, the two ends of belt wheel 5 are provided with rib.Wherein, said axle 6 two ends are supported by selfaligning ball bearing 2 and 7.Selfaligning ball bearing 2 is fixed in the mounting hole of support 3, and by end cap 1 axially locating, the outer ring of selfaligning ball bearing 2 is fixed, and inner ring can adapt to axle 6 and make the interior wallowing motion of several angle scope, is 6 ° with respect to the center allowable angle of inclination.Selfaligning ball bearing 7 is installed in the hole of support 3 the other ends by eccentric bushing 8, and making the eccentric bushing 8 and the mounting hole of support 3 is that little gap is rotatably assorted.Eccentric bushing 8 is pressed on the support 3 by briquetting 9 usefulness bolts, and when briquetting 9 compressed, eccentric bushing 8 can not rotate, and when briquetting 9 unclamped, eccentric bushing 8 can rotate in support 3 holes, drives selfaligning ball bearing 7 and rotates.The outer end of eccentric bushing is provided with end cap 10, and axle 6 is located by connecting by dead axle bolt 11 and end cap 10.Be provided with the adjustment bolt 12 of radial arrangement at the cylindrical of eccentric bushing 8 boss, in order to serve as handle, rotating eccentricity cover 8.Double Tops axle sleeve 4 is used for to belt wheel 5 location, and its end embeds in the radial ball bearing, and is more convenient during installation.
As shown in Figure 3, the center of circle of eccentric bushing 8 cylindrical C and its endoporus decentraction, throw of eccentric P=6mm.Eccentric bushing is carved with groove N on 8 exterior edge faces, the indication eccentric direction, and there is a boss in eccentric bushing 8 outsides, along the screw H that is uniform-distribution with 6 M10 on its cylindrical D, use when adjusting bolt 12 as being screwed into.
Above-mentioned selfaligning ball bearing 2 is identical with 7 models.
During preliminary assembling, the groove N on the eccentric bushing 8 aligns with groove M on the support 3, and this moment, selfaligning ball bearing 2 and 7 was coaxial, not inclination of belt wheel 5.When driving belt sideslip in service need be aligned, unclamp briquetting 9, in the screw H that adjusts on the boss cylindrical D that bolt 12 is screwed into eccentric bushing 8, make handle with it, rotating eccentric sleeve 8, at this moment, selfaligning ball bearing 7 rotates around eccentric bushing 8 cylindrical C centers, and selfaligning ball bearing 2 maintains static, two bearings is no longer coaxial, selfaligning ball bearing 2 and 7 inner ring tilt with axle 6, and the belt wheel 5 that drives on the axle 6 tilts, the levelling driving belt.Whole adjustment process need not shutdown.After regulating, the briquetting bolt is locked, normally stable operation of system.During work, axle 6 is subjected to dead axle bolt 11 effect, can not rotate, and selfaligning ball bearing 2 and 7 are subjected to static load.
The utility model has following beneficial effect:
Need not shutdown when (1) regulating;
(2) deflection-regulating range can reach-6 °～+ 6 °, exceeds common mechanical foozle scope fully, During the driving-belt sideslip, can align normal condition;
(3) simple in structure, required part is that general national standard part or conventional mechanical are made workpiece, becomes This is low;
(4) assembly and disassembly is convenient;
(5) selfaligning ball bearing at two ends only is subjected to static load, the reliability height;
(6) easy to adjust, directly perceived.
