Description

The belt conveyer carrying roller

The utility model relates to a kind of belt conveyer carrying roller, belongs to the accessory equipment of belt conveyer.

Use the belt conveyer carrying roller at present both at home and abroad, as TD75 type, DTII type, IT type, the Sa type of China, the H-PLUS series of the U.S., the ERBO of Germany, gondola RULMECA, belt conveyer carrying rollers such as the KING board in Taiwan.Their weak point is load-carrying capacity deficiency, the interior exocoel shape oil cabinet that does not have inside and outside contact seal to form, the metal matter locating bush that does not also have the bearing special use, low to the service life that makes carrying roller, the anti-dirt exclusion capabilities of drenching is poor, and the oiling road resistance of each bearing is inconsistent.

The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of lubricating grease to be difficult for running off, being difficult for oxidation, recoverable amount abundance, interior contact seal coefficient of friction is little, the outer contacting sealing is externally labyrinth packing slip mutually, the belt conveyer carrying roller of long service life.

The purpose of this utility model is achieved in that the bearing seat that comprises urceolus, symmetry and decline, inside and outside labyrinth packing, inside and outside contact seal, protective cover, and its structural feature is: constitute enclosed cavity shape oil cabinet in the both sides of bearing between the sealing of contact seal and outer contacting; Looping weir notch between outer labyrinth packing and the bearing seat; Be provided with metal matter locating bush between bearing and the protective cover; Protective cover and the clearance opening of outer labyrinth packing formation are opened in the carrying roller inboard; Each bearing is equipped with independent oiling path.

The utlity model has following advantage compared to existing technology:

1, load-carrying capacity is big.Because the utility model adopted tapered roller bearing, exceed 1.5～2 times than the load-carrying capacity of same specification other products.Its gap of bearing clearance of the present utility model is by threaded adjusting, can compensate the Mismachining tolerance of each part, and end float misalignment is lower than 2 times of national normal values.The utility model has designed bearing metal locating bush, and labyrinth packing is not subjected to axial force in can making, thereby has greatly improved the load-carrying capacity of carrying roller.

2, long service life.The utility model has adopted outer labyrinth packing to cooperate the hermetically-sealed construction that forms annular weir notch with bearing seat, makes dustproof, anti-trickle exceed 2 times of national standard.And in bearing both sides grease recoverable amount 2 times of conventional carrying roller.Thereby improved the service life of bearing.Be 60,000 hours specified service life of the present utility model, higher 1.5～2 times than same specification product.

The repairing amount unanimity of novel each bearing of 3, oiling mode.

The explanation of accompanying drawing drawing:

Accompanying drawing is a structural representation of the present utility model.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

The utility model is mounted in the carrying roller of travelling apron transmission belt bottom.Form by urceolus 1, interior labyrinth packing 2, outer labyrinth packing 3, outer contacting sealing 4, metal matter locating bush 5, tapered roller bearing 6, bearing seat 8, protective cover 9, axle 10, press-fit forced filling oil cup 11, location jackscrew 12, annular weir notch 13, oiling path 14.Its design philosophy is: strengthen the load-carrying capacity of carrying roller, change seal form and oiling path to realize goal of the invention.Its urceolus 1 matches with bearing seat 8, and bearing seat 8 symmetries are contained in the urceolus 1.Axle 10, interior contact seal 7, tapered roller bearing 6, outer labyrinth packing 3 all are contained in the urceolus 1.Outer labyrinth packing 3 is bottoms that an exoskeletal ligulate sealing is positioned at bearing seat 8, and there is looping weir notch 13 between one outwardly-bent 90 flanging of spending and the bearing seat its outer.Outer contacting sealing 4, interior labyrinth packing 2 are installed on the metal matter locating bush 5, and they are installed on the axle 10 together, and protective cover 9 is stamped in its outside.Metal matter locating bush 5 is between bearing and protective cover 9.The end of axle 10 is provided with press-fit forced filling oil cup 11, and its effect is to press oil toward oiling path 14.The middle part that oiling path 14 is positioned at axle 10 is communicated with press-fit forced filling oil cup 11.Oiling path 14 is communicated with one by one with coro bearng.As shown in the figure, the bottom that contact seal 7 is positioned at bearing seat 8 in of the present utility model forms tangible oil storage chamber 15 with the outer contacting sealing 4 that is installed on the metal matter locating bush 5, and the setting of this structure can make that lubricating grease does not run off, not oxidation, recoverable amount abundance.For bearing lubrication provides the failure-free assurance.Protection is placed on the seal clearance opening of outer labyrinth packing 3 and opens to the carrying roller inboard, can reduce flying into of dust effectively.

Assembled embodiment of the present utility model: at first section of a pipe is processed into the existing urceolus 1 of the size that matches with bearing seat 8.The urceolus 1 of then bearing seat 8 symmetries being packed into, and adopt circumferential welds to weld urceolus 1 and bearing seat 8 with automatic welding machine tool, dress as axle 10, interior contact seal 7, bearing 6, outer labyrinth packing 3 successively.Again outer contacting sealing 4, interior labyrinth packing 2 are contained on the metal matter locating bush 5, are contained in together then on the axle 10, load onto protective cover 9 at last, adjust the play of bearing 6, and on axle 10, make a call to a hole in by top wire hole, load onto and locate jackscrew 12 in the position of adjusting.

The material of working process of the present utility model and use: the injection grade Polyurethane is adopted in contact seal 7 in the utility model, and fourth cyanogen oil proof rubber or polyamine fat are adopted in outer contacting sealing 4.During use the utility model is installed in the bottom of conveyer transmission belt, outer contacting sealing 4 is externally labyrinth packing 3 slips mutually, and arranged very long service life.In carrying roller when work,, outer labyrinth packing 3 cooperates the back to form with bearing seat 8 annular weir notch 13 can prevent entering of side trickle effectively, and its can be along annular weir notch 13 continuation outflows when the end face of carrying roller flows down in case the side trickle is arranged, or throw away under action of centrifugal force.The axial carrying capacity of tapered roller bearing 6 is big, because the oiling mode is the pointwise oiling, makes each bearing 6 can both obtain quantitatively regular lubricating oil and replenish, and there is interior exocoel shape oil cabinet the both sides of bearing, and the oiling cycle extends, and is 20,000 hours.
