Abstract
The utility model discloses a bearing block, in particular to a nylon bearing block for a carrier roller of a belt conveyer for a coal mine, which comprises a block body, annular teeth, an outer stop cover and an inner stop cover. The annular teeth are arranged on the outer surface of the block body, the outer stop cover is arranged at the end of the block body and connected with the annular teeth, the inner stop cover is disposed on the inner surface of the other end of the block body, and a protecting structure is disposed at the connecting position of the end surfaces of the annular teeth with the surface of the block body. The nylon bearing block has the advantages that the nylon bearing block is simple and practical in structure, prolongs service lives of a bearing and the carrier roller, reduces production cost, and increases production benefit.
Description
Technical field
The utility model discloses a kind of bearing seat, a kind of specifically colliery belt conveyer carrying roller nylined bearing seat.
Background technology
Existing conveying machinery carrying roller, what major part adopted is the steel carrying roller, especially the colliery is with the carrying roller of belt conveyer, the two ends of carrying roller need bearings in bearing seat, it as the disclosed patent No. of China 200820186719.9 utility model patent, a kind of labyrinth type nylon carrying roller is disclosed, this carrying roller by bearings in bearing seat, bearing seat is fit in the roller, roller is generally the roll body of steel, because bearing seat ring tooth end face is the right angle, so the steel roll body can cause the damage to bearing seat when installing, its mechanics and sealing property are all produced certain influence, also influential to the right alignment of the bearing at carrying roller two ends, sometimes in order to eliminate these influences, can carry out turning processing to the roll body inside pipe wall, but many again procedures, and turning processing roll body tube wall inwall is processed with difficulty, and can the simplified inside face circularity of damage roller after the processing.
Summary of the invention
The purpose of this utility model is to be the right angle at above-mentioned technology bottom bracket ring tooth end face, easily bearing seat is caused the shortcoming of damage during installation, a kind of colliery belt conveyer carrying roller nylined bearing seat is provided, it does not need the barrel inwall is carried out turning processing, can directly bearing seat be fit in the barrel, not damage barrel inside face circularity.
The technical scheme that realizes the utility model purpose is as follows:
Colliery belt conveyer carrying roller nylined bearing seat; it comprises the outer door of ring tooth, pedestal end and ring tooth bonded assembly of pedestal, present external surface and the interior door on the pedestal other end inside face, and the end face of ring tooth and surperficial junction are provided with the protection structure.This protection structure is used for protecting when bearing seat being packed into the steel roll body bearing seat injury-free; steel roll body inwall is not being carried out turning processing; guaranteeing that not damaging roll body inside face circularity gets under the situation; the nylined bearing seat of the chamfering fit form with interference is pressed in the steel roll body; and can guarantee the right alignment of bearings at both ends; the bearing at carrying roller two ends is moved coaxial fully getting under the situation; avoid getting in the conventional machining process bearings at both ends disalignment and got phenomenon; do not allow bearing be subjected to any stress influence; the rotational resistance that guarantees carrying roller reduces bottom line, thereby has increased the service life of carrying roller.
Fillet surface or arc surface that end face that described protection structure is a ring tooth and surperficial junction are set.When the installation shaft bearing, at first contact by fillet surface or arc surface with steel roll body inwall, energy better and safer bearing seat is pressed in the roll body prevents the bearing seat damage.
Be provided with the reinforcement circular edges between described ring tooth and the outer door.Strengthen water inlet that circular edges prevents the part that bearing seat and pipe are combined closely, advance grey phenomenon, thereby guaranteed the service life of carrying roller.
The door inboard is provided with rectangle or arc oilway in described.Rectangle or arc oilway can better make the lubricating oil of bearing be applied with mobile, prolong the service life of bearing and carrying roller.
Benefit of the present utility model is simple in structure, practical, has reduced productive costs the service life of having improved bearing and carrying roller, has increased productivity effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the B portion enlarged drawing of Fig. 1;
Fig. 4 is the enlarged drawing of another embodiment of B portion of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3; colliery belt conveyer carrying roller nylined bearing seat; it comprises the interior door 4 on door 3 outside pedestal 1, the ring tooth 2 at pedestal 1 outside face, pedestal 1 end and ring tooth 2 bonded assemblys and pedestal 1 other end inside face; the end face of ring tooth 2 and surperficial junction are provided with the protection structure; the fillet surface 21 that end face that this protection structure is a ring tooth 2 and surperficial junction are set; interior door 4 inboards are provided with the oilway 41 of rectangle, are provided with between ring tooth 2 and the outer door 3 to strengthen circular edges 5.
Above-mentioned protection structure is a fillet surface; this fillet surface is used for protecting when bearing seat being packed into the steel roll body bearing seat injury-free; steel roll body inwall is not being carried out turning processing; guaranteeing that not damaging roll body inside face circularity gets under the situation; the nylined bearing seat of the chamfering fit form with interference is pressed in the steel roll body; and can guarantee the right alignment of bearings at both ends; the bearing at carrying roller two ends is moved coaxial fully getting under the situation; avoid getting in the conventional machining process bearings at both ends disalignment and got phenomenon; do not allow bearing be subjected to any stress influence; the rotational resistance that guarantees carrying roller reduces bottom line; thereby increased the service life of carrying roller, when the installation shaft bearing, at first contacted with steel roll body inwall by fillet surface; energy better and safer bearing seat is pressed in the roll body prevents the bearing seat damage.
Above-mentioned reinforcement circular edges prevent the part that bearing seat and pipe are combined closely water inlet, advance grey phenomenon, thereby guaranteed the service life of carrying roller.
Above-mentioned rectangle oilway can better make the lubricating oil of bearing be applied with mobile, prolongs the service life of bearing and carrying roller.
In this enforcement example, fillet surface can be substituted by arc surface becomes the protection structure, also can play same effect, and other have similar shape and also can be used as the protection structure.
In this enforcement example, oilway also can be the groove of circular arc or the groove of inverted triangular-shaped grooves or other shapes, as long as be convenient to processing, is convenient to the practicality of lubricating oil.
Above embodiment is not to restriction of the present utility model, and the scope of the utility model protection includes but not limited to above embodiment, and any improvement of carrying out on basis of the present utility model all belongs to the scope of the utility model protection.
