Inner guide wheels do not rotate, and chain slides on Inner guide wheels, in maintenance it is sometimes found that Inner guide wheels are worn away 1/4 or 1/3 or so.Due to
Chain slides on Inner guide wheels, also exacerbates the abrasion of chain, have impact on the service life of chain.But Inner guide wheels are in pulp water,
It can not judge whether Inner guide wheels rotate, whether bearing damages.It can only be checked in maintenance.
Utility model content
The utility model is mainly for problem above, there is provided a kind of bearing bore split, rational in infrastructure grease up；
Whether close observation is directly perceived for sealing；On-bne repair, changes bearing, and its technical scheme is as follows：
A kind of novel bearing external inner guide pulley includes：Inner guide pulley, inner guide pulley axle, inner guide pulley seat, bonnet and sealing structure,
The inner guide pulley is connected with inner guide pulley axle using flat key, and the rotation of inner guide pulley drives inner guide pulley axle to rotate, and inner guide pulley seat is arranged on
On the outside of inner guide pulley, connected using bearing between inner guide pulley seat and inner guide pulley axle and sealed by sealing structure, inner guide pulley seat with it is interior
Multiple-sealed structure is used between guide wheel shaft, prevents that pulp water flows out along the gap between inner guide pulley axle and inner guide pulley seat during operation,
Bonnet is connected by screw bolts with inner guide pulley seat, and bearing can be very easily changed when bonnet is pulled down.
On the basis of above-mentioned technical proposal, using packing seal, agent injecting type band between the inner guide pulley seat and inner guide pulley axle
The multiple-sealed structure of leak stopping is pressed, it includes soft packing seal, hard packing sealing and shaped packing seal；Other inner guide pulley end face with
Bonnet includes clearance seal, labyrinth seal mode using non-contact seal.
On the basis of above-mentioned technical proposal, collect cavity, conduction hole, the external water conservancy diversion water of conduction hole are set on the inner guide pulley seat
Pipe, a small amount of buck penetrated into out of cell body flows out through mozzle to be emptied, and is avoided the inside oil sealing of buck contact bearing chamber side, is ensured
Reliable sealing and lubrication.
The utility model bearing bore split, rational in infrastructure grease up；Whether close observation is directly perceived for sealing；Online
Maintenance, change bearing.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
1. inner guide pulley, 2. inner guide pulley axles, 3. inner guide pulley seats, 4. bonnets, 5. sealing structures, 6 collect cavities, 7. conduction holes, 8.
The external water conservancy diversion water pipe of conduction hole.
Embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of novel bearing external inner guide pulley includes：Inner guide pulley 1, inner guide pulley axle 2, inner guide pulley seat 3, after
Lid 4 and sealing structure 5, the inner guide pulley 1 are connected with inner guide pulley axle 2 using flat key, and the rotation of inner guide pulley 1 drives inner guide pulley axle 2
Rotate, inner guide pulley seat 3 is arranged on the outside of inner guide pulley 1, is connected and by close using bearing between inner guide pulley seat 3 and inner guide pulley axle 2
Seal structure 5 is sealed, and multiple-sealed structure 5 is used between inner guide pulley seat 3 and inner guide pulley axle 2, and pulp water is along inner guide pulley when preventing operation
Gap outflow between axle and inner guide pulley seat, bonnet 4 are connected by screw bolts with inner guide pulley seat 3, can be very square when bonnet 4 is pulled down
Just replacing bearing.
Four inner guide pulleys of dragveyer work in buck, and the effectively lubricating of bearing is that can it operate most reliably and with long-term
Important guarantee.To reach above-mentioned purpose, reliable sealing is most important, and this needs the life-span and the sealing position that improve seal
The erosion resistance of rotating shaft.Collect cavity, conduction hole are set on bearing seat, the external water conservancy diversion water pipe of conduction hole, is penetrated into out of cell body
A small amount of buck flows out through mozzle to be emptied, and avoids the inside oil sealing of buck contact bearing chamber side, ensures reliable sealing and lubrication.Together
When also add the design concept of " replacing the lubricating grease being emulsified in time, ensure the effectively lubricating of bearing ", on the outside of cabin plus
If special Large Copacity spinning lubricating cup is simultaneously provided with porus excretorius, can easily realize to inner guide pulley grease up.It is interior
Guide wheel shaft stretches out boring cover, conveniently can observe whether inner guide pulley rotates, be easy to processing to overhaul, this inner guide pulley structure is using outside bearing
Formula is put, i.e. inner guide pulley uses Flat dey joint with inner guide pulley axle, and the rotation of inner guide pulley drives inner guide pulley axle to rotate, and bearing block is led inside
Wheel outside.Coupled between inner guide pulley seat and inner guide pulley axle using bearing and sealing structure, adopted between inner guide pulley seat and inner guide pulley axle
With multiple-sealed structure, prevent that pulp water flows out along the gap between inner guide pulley axle and inner guide pulley seat during operation, our companies use
Self-designed sealing structure, ensure the sealing of inner guide pulley, make inner guide pulley water-tight, service life is grown, and inner guide pulley good seal is
