The utility model discloses a seal structure comprises inside seal circle, external seal circle and middle sealing washer, and inside seal circle and external seal circle looks remote site all are provided with many rings of ring channels, and the bilateral symmetry of middle sealing washer is provided with the many rings of the ring channel complex shape cover that encloses with inside seal circle, external seal, and labyrinth seal structure is formed to the annular cover of middle sealing washer and the ring channel of inside seal circle and external seal circle, can effectively ensure sealed effect, extend bearing's life.
Description
Technical field
The utility model relates to a kind of carrying roller, is specially the antimagnetic anti-static composite material carrying roller of a kind of high-strength corrosion-resistant.
Background technology
Carrying roller is the parts relatively simple for structure of in belt conveyer.The contaminated degree of the bearing in carrying roller is the key factor affecting carrying roller service life.When bearing is not contaminated, when working under good lubricating status, the service life of carrying roller will reach the longest.Polluted to prevent bearing, common way is provided with seal cover cap in the bearing seat in carrying roller, prevents extraneous dust pollution bearing, but such sealing effectiveness or not ideal enough, dust still can pollute bearing from labyrinth seal lid, reduces the service life of carrying roller.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, service life is longer, and can better prevent the carrying roller of extraneous dust pollution bearing.
The technical scheme realizing above-mentioned purpose is: the antimagnetic anti-static composite material carrying roller of high-strength corrosion-resistant, it is characterized in that: comprise roll body, the axial centre of described roll body is provided with roller carrier shaft, the two ends of described roller carrier shaft are respectively arranged with bearing seat, be disposed with ceramic bearing and hermetically-sealed construction from inside to outside in the axle center hole of bearing seat, the roller carrier shaft outside hermetically-sealed construction is provided with back-up ring.
Described hermetically-sealed construction comprises inner seal ring, exterior seal ring and intermediate seal circle, intermediate seal circle is arranged between inner seal ring and exterior seal ring, the bilateral symmetry of intermediate seal circle is provided with multi-ring annular cover, multi-ring annular cover is arranged along interval, periphery thoughtful in intermediate seal circle, the ring shape cover that intermediate seal circle both sides are positioned at inner circumferential is placed through on roller carrier shaft, inner seal ring and exterior seal ring opposite end are provided with multi-ring annular groove, intermediate seal circle both sides other each circle annular sleeve except the circle annular sleeve being positioned at inner circumferential is equipped with at inner seal ring, in the circular groove of exterior seal ring.
The outer ring of described exterior seal ring is provided with a circle and is embedded at barb in bearing seat.
Roll body, roller carrier shaft, bearing seat, inner seal ring, exterior seal ring and intermediate seal circle all adopt glass fibre to make.
The beneficial effects of the utility model:
1, hermetically-sealed construction of the present utility model is made up of inner seal ring, exterior seal ring and intermediate seal circle, inner seal ring and exterior seal ring opposite end are provided with multi-ring annular groove, the bilateral symmetry of intermediate seal circle is provided with the multi-ring annular cover coordinated with the circular groove of inner seal ring, exterior seal ring, the circular groove of the annular sleeve of intermediate seal circle and inner seal ring and exterior seal ring forms labyrinth seal structure, can the effect of effective guarantee sealing, extend service life of bearing.
2, the outer ring of exterior seal ring is provided with a circle and is embedded at barb in bearing seat, makes it not easily can come off from bearing seat,
3, roll body, roller carrier shaft, bearing seat, inner seal ring, exterior seal ring and intermediate seal circle all adopt glass fibre to make, and have good withstanding corrosion, antimagnetizing, antistatic property, and roll body also has good self-lubricating property simultaneously, does not damage belt.
4, ceramic bearing has high temperature resistant, cold-resistant, wear-resisting, withstanding corrosion, antimagnetizing, antistatic, the characteristic such as oil-free self lubrication, high rotating speed, can be used for environment and the special operation condition of extreme.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
