Abstract
The utility model relates to an anti-deviation device for a synchronous belt. A retaining shaft is fixed at the position, which is close to the synchronous belt, on each side of the synchronous belt in a direction perpendicular to a transmission shaft and the synchronous belt, and a bearing is sleeved at the position where the retaining shaft is contacted with the synchronous belt. When the synchronous belt deviates, the retaining shafts and the bearings which are arranged on both sides of the synchronous belt can achieve an effect of limiting the deviation of the synchronous belt, and the bearings can ensure that the friction between the synchronous belt and the retaining shafts is changed from sliding friction to rolling friction, so that the deviation of the synchronous belt is effectively prevented, the wear of the synchronous belt is reduced, the service life of the synchronous belt is prolonged, and the work efficiency is improved.
Description
One, technical field:
The utility model relates to a kind of synchronous band protective gear, is specifically related to a kind of synchronous band anti-deviation device.
Two, background technique:
Belt transmission is a kind of modal machine power kind of drive.Because work for a long time; The swelling degree of belt, the variations such as wearing and tearing of drive wheel all can cause the phenomenon that drivign belt sideslip occurs or comes off; In the less casing of space; Synchronously the sideslip problem of band never has a kind of perfect solution, generally is employed in method that driving wheel, follower edge install back-up ring additional and prevents synchronously the problem with sideslip; The rigidity friction that produces between meeting and the back-up ring behind so synchronous band sideslip causes synchronous band to damage easily, influences the stability of machine work.
Three. summary of the invention:
It is a kind of simple in structure that the purpose of the utility model is to provide, synchronous band anti-deviation device easy for installation.
For realizing above-mentioned purpose, the described a kind of synchronous band anti-deviation device of the utility model is: the both sides at described synchronous band are fixed with the shelves axle with transmission shaft respectively with the position of being with all vertical direction near synchronous band synchronously.
Be set with bearing at said shelves axle with being with position contacting synchronously.
Owing to taked technique scheme; After synchronous band generation sideslip situation, the shelves axle that is installed in synchronous band side can play spacing effect to the sideslip of synchronous band, and bearing can make that the change sliding friction is rolling friction between synchronous band and the shelves axle; Thereby the sideslip that has stoped synchronous band effectively; Reduce the wearing and tearing of synchronous band, prolonged the working life of synchronous band, improved working efficiency.
Four, description of drawings:
Fig. 1 is the structural representation of the described a kind of synchronous band anti-deviation device of the utility model;
Fig. 2 is the side structure schematic representation of a kind of synchronous band anti-deviation device shown in Figure 1.
Five, embodiment:
Visible by Fig. 1 and Fig. 2; The described a kind of synchronous band anti-deviation device of the utility model is: described synchronously with 1 both sides and transmission shaft 2 with synchronously with 1 all vertical direction near being fixed with shelves axle 3 respectively with 1 position synchronously, shelves axle 3 can be fixed on mechanically through bolt arrangement.For reduce synchronously with 1 with the frictional strength of shelves axle 3; Said shelves axle 3 be with 1 position contacting to be set with bearing 4 synchronously, bearing 4 can be selected plain bearing for use, also can select needle bearing for use; One or two is advisable bearing 4 with suit; To guarantee bearing 4 simultaneously and be with 1 on same horizontal plane synchronously, bearing 4 can make be with synchronously 1 with shelves axle 3 between become sliding friction and be rolling friction, reduce shelves spools 3 pairs synchronously with 1 wearing and tearing.After being with 1 the sideslip situation takes place synchronously, shelves axle 3 be sleeved on the shelves axle 3 and just can stop synchronously sideslip effectively with the bearing 4 of 1 position contacting synchronously with 1, to playing spacing effect with 1 motion synchronously.
