Abstract

The utility model provides an adjusting oil filling roller, which is composed of a roller body, a bearing, a roller shaft, labyrinth sealing devices, oil pressing cups, etc., wherein, the roller body and the roller shaft respectively adopt a hollow structure; the hollow pipe of the roller shaft and the two shaft heads of the roller shaft are connected in a screwing way; the roller body and the roller shaft are connected in a rotary way; the labyrinth sealing devices are arranged on a bearing seat of the roller body and the shaft heads of the roller shaft; the rotary shaft heads can be used for regulating the end play of the roller body of the roller; the oil pressing cups are inlaid at the end parts of the shaft heads; the core parts of the shaft heads are provided with axial and radial oil holes. Oil is filled in an oil reservoir through the oil pressing cups to lubricate. The utility model has the advantages of simple structure, material saving, high sealing performance, long service life of the roller, etc.

Description

Adjustable oiling carrying roller

The utility model relates to a kind of carrying roller of belt conveyer.

At present, industry widespread usage such as metallurgy, coal, building materials, electric power, harbour, food, chemical industry be belt conveyer, the use crux of this machinery is the life-span of transfer member carrying roller, and the principal element that influences carrying roller service life depends on the lubricated of carrying roller, a lot of measures have been taked at this problem people, from the structure of carrying roller, lubricating method etc. are improved.For example: ZL90207181.4 discloses a kind of oil-filling type supporting roller, it adopts bolster, outer tube, bearing, bearing seat, interior outer sealing device etc., its feature is that reserve tube and oil hole are set in carrying roller, increase the store oil amount, and change hermetically-sealed construction, make carrying roller be in lubricating status all the time, prolonged the cycle of run of carrying roller.In addition, adopt the oiling carrying roller of other form in addition,, also there is certain problem in aspects such as the adjustment of its carrying roller installing/dismounting, oil storage chamber, carrying roller weight though these carrying rollers have solved the problems such as lubrication and seal of carrying roller.

The utility model is exactly the deficiency that exists according to above-mentioned carrying roller, and a kind of adjustable oiling carrying roller is provided, and alleviates problems such as carrying roller weight with solution carrying roller installation demolition, oil storage chamber adjustment.

The technical solution of the utility model is that such it is made up of roll body, bearing, roll shaft, labyrinth-type excluder, pressure lubricating cup, roll body adopts hollow, roll body and bearing seat are made one, roll shaft is that the spindle nose spiral marking connection by hollow tubular and both sides forms, spindle nose heart portion is drilled with respectively axially and radial direction oil hole, the spindle nose end is inlaid with the pressure lubricating cup, roll body and roll shaft rotation connect, on the bearing seat and the spindle nose of roll shaft of bearing installation in roll body, the labyrinth-type excluder flush fit is contained on the spindle nose of the bearing seat of roll body and roll shaft.There is a bit of distance in this labyrinth-type excluder and the bearing outside, form oil storage chamber.Rotating shaft head just can be adjusted the distance of labyrinth-type excluder and bearing, promptly adjusts the end float misalignment of carrying roller roll body.

Concrete scheme of the present utility model has the outer ring of bearing to be installed on the bearing seat of roll body after processing, and bearing cone is installed on the spindle nose of roll shaft, and fixes with elastic scheibe.Axial and radial direction oil hole on the spindle nose intersects vertically as asphalt channel.

The utility model is owing to adopted hollow roll body and open core type roll shaft, two spindle noses of hollow shaft and hollow tubular spiral marking connection, be drilled with axial and radial direction oil hole on two spindle noses, and employing labyrinth-type excluder, make not only good seal of its roll shaft, and can adjust the end float misalignment of carrying roller roll body, it is in light weight to have a carrying roller, low cost of manufacture, advantages such as operating cycles length.

Below in conjunction with accompanying drawing the utility model is done and to be specified.

Fig. 1 is a structural representation of the present utility model.

The utility model is by roll body 1 as shown in the figure, bearing 3, roll shaft, labyrinth-type excluder 2, press lubricating cup 7 to form, roll body 1 adopts hollow, roll body 1 is made one with bearing seat, roll shaft is to be formed by spindle nose 6 spiral marking connections of hollow tubular 8 with both sides, spindle nose 6 heart portions are drilled with respectively axially and radial direction oil hole, spindle nose 6 ends are inlaid with presses lubricating cup 7, roll body 1 connects with the roll shaft rotation, bearing 3 is installed on the spindle nose of the bearing seat of roll body 1 and roll shaft, the seal ring of labyrinth-type excluder 2 is installed on the spindle nose 6 of bearing seat in the roll body 1 and roll shaft respectively by flush fit, this labyrinth-type excluder 2 has a bit of distance with bearing 3 outsides, forms oil storage chamber 5.Rotating shaft head 6 is adjusted the end float misalignment of the adjustable roller roll body that puts one's child in a boarding nursery of distance of labyrinth-type excluder and bearing 3.The outer ring of bearing 3 is installed on the bearing seat of roll body 1 after processing, and the inner ring of bearing 3 is installed on the spindle nose 6 of roll shaft, and fixing with elastic scheibe 4.Axial and radial direction oil hole on the spindle nose 6 intersects vertically as asphalt channel, can be pressed into oil pocket 5 to lubricating oil by forced filling oil cup 7 through asphalt channel by hand gun during bearing 3 oilings.

Roll body 1 of the present utility model can form with metal tube is rolling, or with processing after the metal casting, also can adopt the non-metallic material manufacturing to form, and so promptly can saving in material influence carrying roller again and normally moves.Holder axle mounting, when dismounting are as long as can realize with spanner rotating shaft head 6 assembling bearings etc.
