Description

Roller bearing of belt conveyer

The utility model relates to belt transporter Idler bearing device.

At present, being widely used in the idler structure that the belt transporter of the bulk material of industries such as metallurgy, chemical industry, water power, building materials, grain, harbour and finished parts joins all is that bearing seat is equipped with at two ends, and bearing and oil sealing are housed in the bearing seat.Owing to adopt this version, axle generally has only 0.03mm with the magnitude of interference of bearing cold charge, and the side roller carrier shaft turns round under the carrying operating mode to become 30 ° of angles with horizon, carrying roller generation end float misalignment, and carrying roller is scurried out when serious; Because the concentricity at accumulated tolerance carrying roller two ends is usually greater than 0.03mm, carrying roller rotates dumb, even carrying roller do not change, and causes carrying roller crust severe wear and is worn through; Idler bearing is lubricated in addition and anti-dust performance is poor, especially turns round under the big operating mode of high temperature dust, and Idler bearing damages easily, and the roller revolving resistance coefficient is big, the consumption of current height.

The purpose of this utility model is in order to overcome the problem of above-mentioned existence, design a kind of simple in structure, cost is low, the rotational resistance coefficient is little, carrying roller not play, improve lubricant effect, improve carrying roller service life, assembling and belt transporter Idler bearing device easy to maintenance.

To achieve these goals, the utility model by the following technical solutions.

Belt transporter Idler bearing device, it is characterized in that: by being contained in the carrying roller two end axles bearing and the overcoat that matches with circular arc in the bearing seat, the ball on the cover groove in circular arc and the adjustment in overcoat, borrowing screw thread to be tightened on axle goes up in groove is provided with the adjustment of ball and overlaps, the lubricating oil that is full of in the gap that cover and multi-purpose cover form in overcoat, adjustment is formed with the multi-purpose cover that locknut is fastened on the axle.

Owing to adopt technique scheme, make that the utility model is simple in structure, cost is low, not low, dustproof, the long service life of little, the high lubricating effect of play, rotational resistance coefficient, power consumption, assembling and easy to maintenance of carrying roller.

Description of drawings:

Accompanying drawing is a belt transporter Idler bearing structure drawing of device.

Below in conjunction with description of drawings the utility model is further described.

Belt transporter Idler bearing device, at first overcoat (1) is contained in carrying roller two end axles bearing (7) lining, and match with circular arc in the bearing seat, again ball (2) is placed on circular arc place in the overcoat, then cover (3) in adjusting is tightened on the axle (5), and adjusts to the optimum position, cover is full of lithium based lubricating oil (9) in overcoat, adjustment, cover multi-purpose cover (4), and multi-purpose cover is fixed on the axle, make multi-purpose cover play the effect of location, stop, oil sealing with locknut (6).Cover, multi-purpose cover, axle, locknut fuse in adjusting like this, and the end homalocephalus of axle is inserted on the fixing support, does not rotate.When transmitting adhesive tape under the carrying operating mode, carrying roller crust (8), bearing seat, overcoat are used ball and are rotated flexibly, the no any play of axle.

For dustproof, can install cover of dust additional with screw at the bearing seat outer face, the dustproof fat of filling in cover of dust.

Claims (1)

1. Belt transporter Idler bearing device, it is characterized in that: by being contained in the carrying roller two end axles bearing and the overcoat that matches with circular arc in the bearing seat, the ball on the cover groove in circular arc and the adjustment in overcoat, borrowing screw thread to be tightened on axle goes up in groove is provided with the adjustment of ball and overlaps, the lubricating oil that is full of in the gap that cover and multi-purpose cover form in overcoat, adjustment is formed with the multi-purpose cover that locknut is fastened on the axle.
