Abstract

The utility model relates to an automatic lubricating rubber-belt conveyer roller. The steel pipe of the roller is coated with a bearing seat. The upper side of a shaft is fastened with a spiral pulling spring. A bearing, an oil seal, and the are formed into a cavity whose inner part is filled with the yellow glyceride. When the roller is rotated, the yellow glyceride in the cavity is driven to rotate. Under the action of the pulling spring, the yellow glyceride is pressed continuously to flow to the inner side of the pulling spring and to lubricate the bearing. The yellow glyceride moves backwards and forwards in the cavity to achieve the purpose of automatic lubrication for the bearing. The utility model solves the problems of dry friction and easy damage for the roller because of bad lubrication for the bearing, and has the advantages of energy consumption reduction, and service life of the roller extension.

Description

The automatic oiling type idler of rubber tape conveyor

The utility model belongs to idler of rubber tape conveyor, particularly a kind of can auto-oiled idler of rubber tape conveyor.

Existing mobile belt conveyor carrying roller, its centre bearer has grease in the outside when assembling, carrying roller is after running half a year to one year, grease around the bearing ball just runs out of, bearing is in the dry grinding state, rotary resistance is big, and energy consumption is big, causes damaging, finally scrap, influence the service life of carrying roller.

The purpose of this utility model provides a kind of can the circulation from the trend bearing and imports grease, and prolongs the bearing idler of rubber tape conveyor in service life.

The utility model by carrying roller steel pipe, monolateral sealed bearings, oil sealing, axle with snap ring, axle, spring is pulled out in oiling, bearing seat is formed, the carrying roller steel pipe is wrapped in bearing seat, the two ends correspondence of axle is equipped with monolateral sealed bearings, oil sealing, axle is fastened on the bearing and the location with snap ring, form between monolateral sealed bearings, oil sealing, the bearing seat cavity, in fill up butter fat, axle tightens intrinsic helix and pulls out spring; When carrying roller rotated, axle was fixing, and carrying roller steel pipe, bearing, bearing seat, oil sealing rotate the butter fat that also drives in the cavity and rotate, and butter fat is being pulled out under the spring effect constantly extruding, lubricating bearings.

The utility model is to form a cavity between by monolateral sealed bearings, oil sealing, bearing seat on the basis of existing carrying roller, and fill up butter fat in the cavity, there is helix to pull out spring and be fixed on the axle in the cavity, butter fat and bearing seat, oil sealing, axle are sticked together because of viscosity, when carrying roller rotates, butter fat in cavity grease pressurized under the effect of pulling out spring constantly moves and lubricating bearings to bearing, make the unlikely dry grinding state that is in of bearing, resistance of motion is little, thereby reduce the complete machine energy consumption of travelling apron, prolong the service life of carrying roller.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a structure cutaway view of the present utility model.

As shown in Figure 1: the utility model by carrying roller steel pipe 1, monolateral sealed bearings 2, oil sealing 3, axle with snap ring 4, spools 5, spring 6 is pulled out in oiling, bearing seat 7 is formed.Carrying roller steel pipe 1 is wrapped in bearing seat 7, and axle 5 two ends are to having monolateral sealed bearings 2, oil sealing 3, and axle is fastened on the axle 5 with snap ring 4, and bearing 2 is played the role of positioning; Form a cavity 9 between monolateral sealed bearings 2, oil sealing 3, the bearing seat 7, fill up butter fat 8 in the cavity 9, be fixed with the helix oiling on the axle 5 and pull out spring 6, when carrying roller rotates, butter fat 8 in the cavity 9 sticks into one and rotates because of viscosity and bearing seat 7, oil sealing 3, bearing 2, spring 6 extruding are rotated and pulled out to butter fat 8, constantly axial shift-in bearing 2, when the sealing lip that moves to bearing 2 when butter fat 8 is obstructed, butter fat 8 is extruded into the outer end of pulling out spring 6 again, reaches continuous purpose to bearing 2 circulating oilings.
