Abstract
The utility model relates to mine transport equipment, in particular to a dust-proof and waterproof rotary drum, and solves the problem that the dust-proof and the waterproof performances of the conventional rotary drum are poor. The dust-proof and waterproof rotary drum comprises a drum surface, a rotary shaft, a bearing, a bearing support and a flange, wherein a sealing device is mounted between the rotary shaft and the bearing support, and comprises a permanent magnetic ring embedded in the bearing support; the outer side surface of the permanent magnetic ring is in interference fit with the inner ring of the bearing support; two annular polarity shoes are mounted on end surfaces on two sides of the permanent magnetic ring respectively; the end surfaces of the annular polarity shoes are in tight fit with the end surface of the permanent magnetic ring; the annular polarity shoes are sleeved on the rotary shaft; the inner side surfaces of the annular polarity shoes are in clearance fit with the outer side surface of the rotary shaft; and a magnetic fluid is filled in the gaps between the annular polarity shoes and the rotary shaft. The dust-proof and waterproof rotary drum effectively solves the problem that the dust-proof and the waterproof performances of the conventional rotary drum are poor, and is suitable for mine transportation.
Description
Technical field
The utility model relates to mine transportation equipment, specifically is a kind of dustproof and waterproof cylinder.
Background technology
Cylinder is the major part of belt conveyer, seriously influences the normal operation and the production of belt conveyer the service life of cylinder.Belt conveyer makes the roller bearings corrosion through regular meeting because of the entering of water and dust at work and grinds destruction, causes the compelled cylinder of changing, and has influence on the safety and nondestructive operation of equipment.For avoiding the roller bearings corrosion and grinding destruction, need seal roller bearings.At present, lip-type seal is generally adopted in the sealing of roller bearings.But in use there is contact pressure problem pockety usually in lip-type seal, causes the water proof and dust proof poor-performing of cylinder thus, thereby influences the service life of cylinder.Based on this,, be necessary to invent a kind of dustproof and waterproof cylinder for solving existing cylinder in use bearing easy-to-rust and the problem of grinding destruction.
Summary of the invention
The utility model provides a kind of dustproof and waterproof cylinder in order to solve the problem of existing cylinder water proof and dust proof poor-performing.
The utility model is to adopt following technical scheme to realize: the dustproof and waterproof cylinder comprises a skin, S. A., bearing, bearing seat and connects dish; Between S. A. and the bearing seat sealing arrangement is installed; Said sealing arrangement comprises the permanent magnet rings that is set in the bearing seat; Ring forms interference fit in permanent magnet rings lateral surface and the bearing seat; Permanent magnet rings both sides end face respectively is equipped with annular polarity boots, and annular polarity boots end face and permanent magnet rings end face form and closely cooperate; Annular polarity boots are set on the S. A., and annular polarity boots medial surface and S. A. lateral surface form free-running fit, are perfused with magnetic fluid in the gap between annular polarity boots and the S. A..
During work, permanent magnet rings forms magnetic loop through annular polarity boots, magnetic fluid, S. A..Under the magnetic action of permanent magnet rings, magnetic fluid firmly is adsorbed on forms magnetic fluid O V-shaped ring in the gap between annular polarity boots and the S. A., thus with clearance seal, thereby realize the sealing to roller bearings.Compare with lip-type seal, magnetic fluid O V-shaped ring has the advantage that contact pressure is evenly distributed.Based on this, to compare with existing cylinder, the described dustproof and waterproof cylinder of the utility model is owing to adopted the sealing arrangement of brand new, and its water proof and dust proof performance is better, longer service life.Thus, the described dustproof and waterproof cylinder of the utility model has thoroughly solved the problem of existing cylinder water proof and dust proof poor-performing.
The utility model is rational in infrastructure, design is ingenious, efficiently solves the problem of existing cylinder water proof and dust proof poor-performing, is applicable to the mine transportation.
