Description
Technical field
The utility model relates to a kind of idler for belt conveyer, belongs to the band conveyor accessory.
Background technology
Band conveyor is important material transfer equipment, is widely used in industries such as salt industry, chemical industry, harbour, mine, and carrying roller is the major part of band conveyor, and consumption is big, requires sternly, to the normal operation decisive role of band conveyor.Mainly there is following problem in existing carrying roller: sealing property is bad, and in use, dust is invaded inside easily, enters bearing track, causes the rotten curing of grease, has aggravated the wearing and tearing of bearing, causes carrying roller to damage; Cylinder wherein, bearing seat, door and bolster are carbon steel structure, and weight is big, easily produce static, and easy-to-rust damages, and all affect the service life of carrying roller.
The utility model content
The purpose of this utility model is to provide a kind of improved idler for belt conveyer, and is in light weight, and sealing, anti-dust performance is good, and electrostatic prevention, rust protection, long service life.
Idler for belt conveyer described in the utility model, comprise cylinder, bolster, bearing and sealing member, cylinder is assemblied on the bolster, bearing installation is between cylinder and bolster, its bearing is contained on the bearing seat, composite plastic cylinder and composite plastic bearing seat interference assembling, the interior exterior seal ring of conventional labyrinth type of mutual fastening is equipped with in the composite plastic bearing seat neck bearing outside, constitute non-contacting seal, inner seal ring is captiveed joint with bearing seat, exterior seal ring is captiveed joint with bolster, the outside of exterior seal ring is provided with back-up ring, and back-up ring places in the circlip groove of bolster, and the outside of back-up ring is provided with end cover, end cover and composite plastic cylinder and composite plastic bearing seat sealing contact, end cover and bolster interference assembling.
Described idler for belt conveyer is established the annulus projection in the bearing seat outer end, and end cover is the oil proof rubber end cover, and end cover contacts with the annulus raised seals of bearing seat, strengthens sealing property.
Described idler for belt conveyer is set up defences in the exposed length appearance of bolster and to be protected coating, as chromium plating, zinc-plated etc., strengthens barrier propterty, resistant to rust.
The utility model design is ingenious, has adopted multiple seal approach, sealing, anti-dust performance is good, and cylinder, bearing seat changed into by composite plastic make, end cover is made by the oil resistant caulking gum, and is in light weight, cost is low, electrostatic prevention, non-corroding is set up defences in the exposed length appearance of bolster and to be protected coating, further strengthen barrier propterty on the whole, prolonged service life greatly.
