Abstract
The utility model relates to a high-temperature and dust-proof self-lubricating riding wheel, consisting of a base wheel 1, a retaining ring 2, a fixed sleeve 3, a graphite sleeve 5 and graphite packing 6, wherein, the inner hole of the base wheel is connected with the graphite sleeve, and the length of the graphite sleeve is smaller than that of the inner hole of the base wheel; the graphite sleeve is installed on the fixed sleeve, and the graphite packing are embedded at the two ends of the graphite sleeve; one end of the graphite packing is limited by the fixed sleeve, and the other end of the graphite packing is limited by the retaining ring; and the retaining ring is connected with the fixed sleeve through screw threads, and the fixed sleeve can be welded on a shaft 4. When the riding wheel is installed, the shaft and the fixed sleeve are connected together in a welding way at scene, which is favorable for adjusting the installing position of the base wheel; the fixed sleeve, the high-strength graphite sleeve, the base wheel and the retaining ring form a high-temperature friction pair which has low friction coefficient, rotates flexibly, can bear a certain load and operate stably at high temperature; the retaining ring and the fixed sleeve are connected through the screw threads so as to play an anti-loosening role; and the graphite packing has the high temperature resistant, dust-proof and sealing functions.
Description
Technical field
The utility model belongs to technical field of conveying machinery, especially a kind of high temperature self-lubricating support roller that prevents dust.
Background technology
The support roller that electrical production is delivered coal and used in the system owing to there is a large amount of fly ash, causes bearing in the system to produce abrasive wear and lost efficacy.The bearing that uses mainly is a plain bearing at present, and the employing antifriction-bearing box is also arranged.Plain bearing adopts the steel to steel friction pair, and product does not have sealing, easily advances dust, also can produce adhesive wear during high temperature.Antifriction-bearing box lubrication failure when high temperature produces seize.
Summary of the invention
In order to address the above problem, the utility model has designed the dustproof self-lubricating support roller of a kind of high temperature, have simple in structure, rotate flexibly, can bear under certain load, the high temperature stable.
For achieving the above object, the utility model adopts following technical scheme:
The dustproof self-lubricating support roller of described high temperature is made of base wheel, baffle ring, fixed cover, graphite cannula, graphite packing, in base wheel endoporus, connect graphite cannula, the length of graphite cannula is less than hole length in the base wheel, graphite cannula is installed on the fixed cover, be inlaid with the graphite packing at the graphite cannula two ends, graphite packing one end is spacing by the fixed cover end, and its other end is spacing by baffle ring, baffle ring and fixed cover are by thread connection, and fixed cover can be welded on the axle.
Because adopt aforesaid technical scheme, the utility model produces following good effect:
1, axle and fixed cover adopt field welding to link together, and are beneficial to the installation site of adjusting the base wheel.
2, fixed cover, high-strength graphite cover, base wheel, baffle ring are formed high temperature resistant friction pair, and this friction pair friction coefficient is low, rotates flexibly, can bear certain load, at high temperature smooth operation.
3, baffle ring and fixed cover thread connection have locking effect.
4, the graphite packing plays the effect of high temperature resistant exclusion seal.
Description of drawings
Fig. 1 is the utility model structural representation;
Among Fig. 1: 1-base wheel; 2-baffle ring; 3-fixed cover 4-axle 5-graphite cannula; 6 one graphite packings.
The specific embodiment
In conjunction with Fig. 1, the dustproof self-lubricating support roller of high temperature of the present utility model is by base wheel (1), baffle ring (2), fixed cover (3), graphite cannula (5), graphite packing (6) constitutes, in base wheel (1) endoporus, connect graphite cannula (5), the length of graphite cannula (5) is less than base wheel (1) interior hole length, graphite cannula (5) is installed on the fixed cover (3), be inlaid with graphite packing (6) at graphite cannula (5) two ends, graphite packing (6) one ends are spacing by fixed cover (3) end, its other end is spacing by baffle ring (2), baffle ring (2) passes through thread connection with fixed cover (3), and fixed cover (3) can be welded on the axle (4).
The utility model utilizes the temperature tolerance of high-strength graphite and good self-lubricating property, in design, adopt graphite cannula (5) and add leak free graphite packing (6) and produce friction pair with steel, during installation, axle (4) and fixed cover (3) adopt field welding to be linked together, and are beneficial to the installation site of adjusting base wheel (1).Fixed cover (3), high-strength graphite cover (5), base wheel (1), baffle ring (2) are formed high temperature resistant friction pair, and this friction pair friction coefficient is low, rotate flexibly, can bear certain load, at high temperature smooth operation.Baffle ring (2) has locking effect with fixed cover (3) thread connection.Graphite packing (6) plays the effect of high temperature resistant exclusion seal.
Claims (1)
1, a kind of high temperature self-lubricating support roller that prevents dust, it is characterized in that: this support roller is by base wheel (1), baffle ring (2), fixed cover (3), graphite cannula (5), graphite packing (6) constitutes, in base wheel (1) endoporus, connect graphite cannula (5), the length of graphite cannula (5) is less than base wheel (1) interior hole length, graphite cannula (5) is installed on the fixed cover (3), be inlaid with graphite packing (6) at graphite cannula (5) two ends, graphite packing (6) one ends are spacing by fixed cover (3) end, its other end is spacing by baffle ring (2), baffle ring (2) passes through thread connection with fixed cover (3), and fixed cover (3) can be welded on the axle (4).
