Abstract
The utility model discloses a kind of ground roller bearing simple dust preventing device, relate to roller arrangement field, a kind of ground.The problems such as the gland that the utility model solves current ground roll is installed wastes time and energy, waste material and barrel body rotation is dumb.This ground roller bearing simple dust preventing device comprises cylindrical shell, axis, bearing and gland, cylindrical shell is flexibly connected by bearing with axis, a gland is respectively provided with inside cylindrical shell two ends, the outside of described each gland is provided with an annular and rises card, and the annular that the outside being positioned at gland inside cylindrical shell two ends is provided with the corresponding depression of the card that to rise with annular rises hole.Use the utility model ground roller bearing simple dust preventing apparatus structure simple, time saving and energy saving, save material and barrel body rotation is flexible.
Description
Technical field
The utility model relates to a kind of ground roll, particularly relates to a kind of ground roller bearing simple dust preventing device.
Background technology
Current underground coal mine inclined gallery or waste tor directly contact for preventing hoisting cable to be in operation with roadway floor and track sleeper and produce mutual wearing and tearing in elevator system, hoisting cable support in suitable height, makes steel rope and base plate and sleeper depart from and avoid direct friction by the mode mainly taking to arrange ground roll on base plate.Ground roll is normally made up of cylindrical shell, axis, bearing and gland, and as shown in Figure 2, the bearing that gland is mainly used for preventing dust from entering and is fixed on bearing seat is interior to protect bearing to extend the service life of bearing.Gland and the cylindrical shell of present use are generally be connected by fastener and screw fastening, as shown in Figure 2, this needs to beat screw hole on the one hand on gland, and normally on gland, symmetry makes a call to six screw holes, also need to beat corresponding screw hole on cylindrical shell on the other hand, therefore waste time and energy; Gland is arranged to internal gland and outer press cover by the tube structure reason of the ground roll even had and needing could realize the fixing of cylindrical shell and gland and the dustproof effect to bearing preferably, so just makes ground roll structure more complicated; Gland is fixed by screw and cylindrical shell simultaneously, and this affects the alerting ability of cylindrical shell around central axis to a certain extent.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of structure simple, time saving and energy saving, save material and barrel body rotation roller bearing simple dust preventing device flexibly.
For achieving the above object, the utility model provides a kind of ground roller bearing simple dust preventing device, comprise cylindrical shell, axis, bearing and gland, cylindrical shell is flexibly connected by bearing with axis, a gland is respectively provided with inside cylindrical shell two ends, the outside of described each gland is provided with an annular and rises card, and the annular that the outside being positioned at gland inside cylindrical shell two ends is provided with the corresponding depression of the card that to rise with annular rises hole.
The rise width in hole of described annular is greater than annular and rises the thickness of card, and the rise two ends of card of described annular are respectively arranged with the hole clipping that rises.
The utility model beneficial effect is: ground of the present utility model roller bearing simple dust preventing apparatus structure is simple, handling ease; Certain manpower is saved, for enterprise saves considerable wage cost because not needing to beat screw hole on gland and cylindrical shell; Exempt and use screw and outer press cover, therefore reduce the cost of raw material to a certain extent; Owing to not needing to use outer press cover, so also just do not need to arrange the car hole corresponding with outer press cover inside cylindrical shell two ends, thus save manually further; Screw and screw hole structure is replaced to make cylindrical shell more flexible around central axis by bearing owing to using annular card and the annular pore structure that rises that rises.
Below in conjunction with accompanying drawing, ground of the present utility model roller bearing simple dust preventing device is described further.
Accompanying drawing explanation

Fig. 4 is that annular of the present utility model rises card structure schematic diagram.
In figure: 1, cylindrical shell, 2, axis, 3, bearing, 4, gland, 5, annular rises card, 6, annular rises hole, 7, screw, 8, screw hole, 9, rise hole clipping.
Detailed description of the invention
As shown in Figures 1 and 3, the ground roller bearing simple dust preventing device of the present embodiment comprises cylindrical shell 1, axis 2, bearing 3 and gland 4, and cylindrical shell 1 is flexibly connected by bearing 3 with axis 2.A gland 4 is respectively provided with inside cylindrical shell 1 two ends.As shown in Figure 4, the outside of each gland 4 is provided with an annular and rises card 5, and the rise two ends of card 5 of annular are respectively arranged with the hole clipping 9 that rises.As shown in Figure 3, the annular that the outside being positioned at gland 4 inside cylindrical shell 1 two ends is provided with the corresponding depression of the card 5 that to rise with annular rises hole 6, and the rise width in hole 6 of annular is greater than annular and rises the thickness of card 5.
Inside the two ends of cylindrical shell 1, gland 4 is placed respectively after the utility model installs bearing 3 between axis 2 and cylindrical shell 1, then the annular by caving in inside cylindrical shell 1 two ends rises, and hole 6 is interior settles the annular card 5 that rises namely to complete the installation procedure of whole ground roll, and operation is very easy.As shown in Figures 2 and 3, owing to using rise card 5 and annular of annular to rise after hole 6 structure replaces screw 7 and screw hole 8 structure, because cover plate 4 and cylindrical shell 1 are not be completely fixed by screw 7, thus cylindrical shell 1 is made to rotate more flexible by bearing 3 around axis 2.
Claims (2)
1. a ground roller bearing simple dust preventing device, comprise cylindrical shell, axis, bearing and gland, cylindrical shell is flexibly connected by bearing with axis, a gland is respectively provided with inside cylindrical shell two ends, it is characterized in that, the outside of described each gland is provided with an annular and rises card, and the annular that the outside being positioned at gland inside cylindrical shell two ends is provided with the corresponding depression of the card that to rise with annular rises hole.
2. roller bearing simple dust preventing device, is characterized in that according to claim 1ly, and the rise width in hole of described annular is greater than annular and rises the thickness of card, and the rise two ends of card of described annular are respectively arranged with the hole clipping that rises.
