Abstract
The utility model relates to a universal joint bearing roller on belt conveyor, characterized by well roller are cylindrical cavity, control the roller and constitute by parts such as mandrel, seal ring subassembly, sealed lid, bearing body, thrust bearing, journal bearing, roller body. Compared with the original roller, the roller has better waterproof and dustproof functions, extremely small abrasion, greatly prolonged service life, safe and convenient use, greatly reduced maintenance cost and production cost, and is an ideal updating product of the existing carrier roller.
Description
The utility model relates to the carrying roller on a kind of band conveyor, particularly a kind of two anti-universal-joint carrying rollers.
Axis is all adopted in three joint pulley type carrying roller inside in the past, connects with pin on spindle nose between the roller, and every joint roller has a radial bearing and seal ring in the two ends.Axle does not rotate when operation, have only roller to rotate, the then direct and seal ring friction of axle, time of run is not long, seal ring (being rubber or plastics) has been destroyed sealing function by the axle severe wear, and is subjected under extraneous coal water or the invasion of other dust, they will enter in the bearing along the gap between axle and the seal ring, make bearing very quick-wearing scrap.Its service life is very short, and generally only about six months, few then has only two, three months.Roller is in operation as one or two bearing failure occurring in addition, and this roller is with regard to stall, and other roller turns round in the same old way, will make belt skew, and severe wear even draw badly, causes stop work and production even brings bigger loss and fatal accident.Because this carrying roller damages easily, need frequently to repair, its service expenditure and productive costs also increase substantially.
In view of present carrying roller exists above-mentioned defective, the purpose of this utility model provides a kind of long service life, does not need frequent maintenance, and is safe in utilization, do not damage belt, can obviously reduce the universal-joint carrying roller with waterproof and dustproof function of service expenditure and productive costs.
Fig. 1 is the scheme drawing of this universal-joint carrying roller.Be to draw conveniently only draw half of carrying roller full figure symmetry of Fig. 1.
This supporting roller for universal joint is three joint rollers, and roller is cylindrical cavity in it is characterized by, about the internal structure of two rollers identical. Roller inside, the left and right sides forms by parts such as axle (1), ring assembly (2), seal cover (3), bearing body (4), thrust bearing (5), journal bearing (6), roller bodies (7), connect with adopting universal joint (8) being connected of middle roller (9), the hanging hook for connecting form that supports with both sides or other form are connected all can. In seal cover (3) and bearing body (4), be provided with dust-proof lubricating Circulating tanks (10), lubricant grease is all filled in parts 2～6 and 10 inside, and main rising lubricated and dustproof effect. Axle (1) is semiaxis, the hook of it and outside is solidly installed, the interior ring of the axle that is in operation (1), ring assembly (2) and seal cover (3) do not rotate, and the outer shroud of ring assembly (2), bearing body (4), thrust bearing (5), journal bearing (6), roller body (7), universal joint (8), middle roller (9) be simultaneously rotation then. Cooperation between axle (1) and black box (2), seal cover (3), bearing body (4), the roller body (7) is interference fits, gapless. Roller body (7) is connected with universal joint (8), is to be welded on the roller body (7) with the connecting plate on the universal joint (8), has been hermetic. Ring assembly (2) adopts the labyrinth collar sealing, and it has interior ring and outer shroud. Bearing body (4) is the place of placing thrust bearing (5) and journal bearing (6), and bearing and body are integrated entirely, and the same roller body of bearing body (4) (7) is solidly installed with screw or alternate manner. The effect of thrust bearing (5) is the parts of the axial force when bearing the carrying roller operation, the effect of journal bearing (6) is the parts of the radial load when bearing the carrying roller operation, the combination utilization of two kinds of rolling bearings, solved carrying roller radial and axial frictional resistance in service, made the rotational resistance of whole carrying roller reduce to minimum of a value.
Because the structure design of this carrying roller is comparatively reasonable, and better seal and lubricating system are arranged, thereby water and dust all advance less than the bearing the inside to go, and can not produce a frictional failure to bearing and axle, thereby will prolong greatly its service life.Through present experimental test, the carrying roller of comparable original design will prolong more than 5～6 times.And new carrying roller three joint rollers when operation are synchronous fully, can not cause the belt skew or draw bad belt, and are safe in utilization, easy installation and removal, maintaining is simple, adopts it can reduce maintaining expense and productive costs greatly, is the comparatively desirable renewal product of carrying roller.
Fig. 1 also can be used as embodiment scheme drawing of the present utility model.
Claims (5)
1, a kind of two anti-universal-joint carrying rollers of three joint pulley types that constitute by radial bearing (6), roller body (7), roller is a cylindrical cavity in it is characterized in that, left and right sides roller also is provided with axle (1), ring assembly (2), seal cover cap (3), bearing body (4), thrust baring parts such as (5).
2,, it is characterized in that left and right sides roller is connected employing universal-joint (8) and connects with middle roller according to the described two anti-universal-joint carrying rollers of claim 1.
