Abstract
The utility model relates to a roller rotation sealing and dust preventing structure applied to a belt conveyor, and in particular relates to a roller rotation sealing and dust preventing structure applied to a self-moving tail of a crossheading belt conveyor used in an underground coal mine. The roller rotation sealing and dust preventing structure is used for solving the problems that an oil seal is worn and sealing is out of service since the coal dust enters the sealing part of an existing roller. The roller rotation sealing and dust preventing structure is characterized by dividing the gland for the outer ring of a roller bearing into an inner gland and an outer gland; simultaneously, the inner gland and the outer gland are mutually nested with the labyrinth inner cavity of a bearing gland for the inner ring; the outer gland at the outmost side of the roller bearing is conical; and an oil filling cup is arranged on the outer side of gland for the roller bearing. The roller rotation sealing and dust preventing structure provided by the utility model has the following beneficial effects that solid particles such as coal hardly enter the oil seal, and therefore, the labyrinth sealing effect is improved.
Description
Affiliated technical field
The utility model relates to a kind of belt conveyer drum rotating sealed dustproof structure, is a kind of drum rotating sealed dustproof structure for the coal mine downhole crossheading Belt Conveyor Moving Drive End specifically.
Background technology
The work condition environment of coal mine downhole crossheading Belt Conveyor Moving Drive End cylinder is poor, coal and other particulate matters mix with water, pile up at cylinder mandrel place, enter into bearing by rotary seal easily, the seal form in " oil sealing+labyrinth " that common structure adopts is because labyrinth channel is shorter, coal and other hard particles are easy to arrive by the labyrinth rubber lip of oil sealing, cause the lip damage, cause seal failure, and then cause oil leak or even bearing failure.
Summary of the invention
Seal the oil sealing wearing and tearing that the position causes because coal dust enters in order to overcome existing cylinder, thereby cause the problem of seal failure, the utility model provides a kind of rotary seal dustproof structure.
The technical scheme that its technical matters that solves the utility model adopts is: with the outside race gland be divided into internal gland, outer press cover is two-layer, inside and outside gland is mutually nested with the labyrinth inner chamber of the Bearing housing of inner ring simultaneously, maze path prolongs, and there be tortuous the variation, increased the difficulty that the particulate matters such as coal enter; The roller bearings outer press cover is inner conical, produces centnifugal force during drum rotating, and particulate matter and the liquid that will adhere to are dished out, and realize self-cleaning; The roller bearings gland is provided with the oiling lubricating cup, is convenient to inject grease in the picture labyrinth, improves the labyrinth packing effect.This Assembled rotary sealed dustproof structure processing technology is simple, and sealing property is reliable, improves cylinder service life.
Description of drawings
Fig. 1 is the mounting structure scheme drawing of roller bearings sealing of the present utility model.
Among the figure: 1, mandrel, 2, barrel, 3, bearing, 4, rubber oil sea, 5, internal gland, 6, Bearing housing, 7, outer press cover, 8, nut, 9, lubricating cup.
The specific embodiment
The technical scheme that its technical matters that solves the utility model adopts is: the outside race gland can be divided into internal gland 5 and outer press cover 7 is two-layer, the centre is Bearing housing 6, internal gland 5 is mutually nested with the labyrinth inner chamber of Bearing housing 6 with outer press cover 7, and maze path prolongs, and has tortuous the variation; Outer press cover 7 is inner conical; Bearing housing 6 is provided with oiling lubricating cup 9.
Because the maze path between internal gland 5, outer press cover 7 and Bearing housing 6 threes is long, and there be tortuous the variation, increased the difficulty that the particulate matters such as coal dust enter; The outermost outer press cover 7 of bearing seat is inner conical, produces centnifugal force during drum rotating, and particulate matter and the liquid that will adhere to are dished out, and realize self-cleaning; Bearing housing 6 is provided with oiling lubricating cup 9, is convenient to inject grease in the labyrinth, increases the labyrinth packing effect, simultaneously, injects grease by the cycle, extrudes protection rubber oil sea lip with entering particulate matter in the labyrinth etc.
Claims (3)
