Abstract
The utility model discloses a kind of axle sealing structure of carrying roller, comprise running roller, main shaft, bearing and seal ring, stretch into after spindle end is connected with bearing fit in running roller; Rubber seal rings for seal is passed through in running roller and main shaft joint; It is characterized in that described main shaft being arranged more than one diaphragm seal I, described running roller lower end arranges more than one diaphragm seal II; There is gap between described diaphragm seal I and running roller, between described diaphragm seal II and main shaft, have gap; Described diaphragm seal I is disposed adjacent with diaphragm seal II; Gap is had between described diaphragm seal I and seal ring.The utility model arranges diaphragm seal respectively on main shaft and running roller, makes it and forms radial loop between seal ring, extends dust inlet passage, decrease dust inlet, improve seal ring working life, and then improve the operating time of whole carrying roller, reduce enterprise's cost of production.
Description
Technical field
The utility model relates to a kind of axle sealing structure of carrying roller, belongs to conveying equipment field.
Background technique
At present, belt conveyor and chain conveyor need to arrange carrying roller load-bearing, is moved ahead by friction rolling auxiliary belt and chain simultaneously.In the working environment that the amount of dust such as cement plant, ore deposit factory are larger, owing to there being gap between roller and main shaft, after working long hours, having a large amount of dust enters in running roller, accumulate in seal ring place shaping and with seal ring friction, seal ring can be caused to damage.This just causes the minimizing in carrying roller working life, and seal ring is arranged in running roller simultaneously, and it is also very inconvenient to change.
Model utility content
For overcoming above-mentioned deficiency, the utility model object is to provide a kind of axle sealing structure extending the carrying roller in carrying roller working life.
Scheme of the present utility model is as follows: a kind of axle sealing structure of carrying roller, comprises running roller, main shaft, bearing and seal ring, stretches in running roller after spindle end is connected with bearing fit; Rubber seal rings for seal is passed through in running roller and main shaft joint; Described main shaft is arranged more than one diaphragm seal I, described running roller lower end arranges more than one diaphragm seal II; There is gap between described diaphragm seal I and running roller, between described diaphragm seal II and main shaft, have gap; Described diaphragm seal I is disposed adjacent with diaphragm seal II; Gap is had between described diaphragm seal I and seal ring.Seamless between diaphragm seal I and axle, seamless between diaphragm seal II and roller, form radial seal loop.
Further, main shaft and running roller junction are from first setting gradually according to diaphragm seal I, diaphragm seal II order near seal ring end.
Further, main shaft and running roller junction are from first setting gradually according to diaphragm seal II, diaphragm seal I order near seal ring end.
Further, described diaphragm seal I and main shaft are connected and fixed by the mode of close-fitting, diaphragm seal II by the mode fixed roll that welds or engage on wheel.
The utility model structure is simple, easy to assembly.The utility model arranges diaphragm seal respectively on main shaft and running roller, makes it and forms radial loop between seal ring, extends dust inlet passage, decrease dust inlet, improve seal ring and bearing working life, and then improve the operating time of whole carrying roller, reduce enterprise's cost of production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view at the utility model C place.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
An axle sealing structure for carrying roller, comprises running roller 1, main shaft 6, bearing 2 and seal ring 3, and main shaft 6 termination and bearing are joined after 2-in-1 connection and stretched in running roller 1; Running roller 1 and main shaft 6 joint are sealed by rubber seal 3; Main shaft 6 is arranged more than one diaphragm seal I 4, running roller 1 lower end arranges more than one diaphragm seal II 5; There is gap between diaphragm seal I 4 and running roller 1, between diaphragm seal II 5 and main shaft 6, have gap; Diaphragm seal I 4 is disposed adjacent with diaphragm seal II 5; Gap is had between diaphragm seal I 4 and seal ring 3.
The utility model is in concrete enforcement, and main shaft and running roller junction are from first setting gradually according to diaphragm seal I, diaphragm seal II order near seal ring end.Also can set gradually according to diaphragm seal II, diaphragm seal I order.
Diaphragm seal of the present utility model I and main shaft are connected and fixed by the mode of close-fitting, diaphragm seal II by the mode fixed roll that welds or engage on wheel.
As Fig. 2, the utility model is established between diaphragm seal I and running roller gap, and seamless between axle; Gap is had between diaphragm seal II and main shaft, and seamless between roller; Have gap between diaphragm seal I and seal ring, these gaps form radial seal loop.
Define one section of radial loop 7, extend dust inlet passage, decrease the amount of friction between dust and seal ring, improve seal ring working life.
Although give detailed description and explanation to embodiment of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned mode of execution and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection domain of the present utility model.
Claims (4)
