Abstract
The utility model relates to the mine leather belt conveyer carrying roller.Problem to be solved is: the mine leather belt conveyer carrying roller that a kind of good seal performance, long service life are provided.Characteristics are: A, its bearing seat are the flange plate-like, and seat is provided with bearing, seal ring and ring washer in the hole successively; Bearing block flange face edge is provided with the arc limit of turning up; Described seal ring is a multilayer words polyurethane seal ring; Two pipe ends of B, described idler pipe are bent, are packaged in outside the bearing block flange end face in radially.The utility model carrying roller life-span is improved 4-6 doubly; Carrying roller weight saving reduces the starting power of band conveyor thereupon; Can effectively prevent to tear conveyer belt, prolong belt service life; Can effectively prevent the stolen of bearing.
Description
Technical field
The utility model relates to the mine leather belt conveyer carrying roller.
Background technology
Existing mine leather belt conveyer carrying roller, seal by interference between its idler pipe and the bearing seat, poor reliability, using stressed back easily to produce relatively moves, simultaneously, carrying roller adopts a cover nylon labyrinth seal sealing in the bearing outside, thereby dust, steam are entered in the carrying roller, and then enters bearing.On the other hand, adopt the atmospheric carbon dioxide gas shield welding to be welded to connect between idler pipe and the bearing seat, tend to tear belt, reduce the service life of belt.
Summary of the invention
The purpose of this utility model is: the mine leather belt conveyer carrying roller that a kind of good seal performance, long service life are provided.
Concrete structural design scheme is as follows:
The mine leather belt conveyer carrying roller comprises roller carrier shaft, idler pipe; Idler pipe is respectively equipped with bearing block assembly in the two ends, and described bearing block assembly comprises bearing seat, bearing, seal ring and ring washer, it is characterized in that:
A, described bearing seat are the flange plate-like, and seat is provided with bearing, seal ring and ring washer in the hole successively; Bearing block flange face edge is provided with the arc limit of turning up; Described seal ring is a multilayer words urethane seal circle;
Two pipe ends of B, described idler pipe are bent, are packaged in outside the bearing block flange face in radially.
Mine leather belt conveyer carrying roller according to above-mentioned is characterized in that: described seal ring madial wall is provided with three sealing bulge loops, and the axial cross section of sealing bulge loop is down bell mouth shape.
Mine leather belt conveyer carrying roller according to above-mentioned is characterized in that: described bearing seat seat hole depth is the 30-45 millimeter.
The utlity model has the advantage of several respects:
1, the utility model adopts multilayer words urethane seal circle, and is tight-closed, prevents the intrusion of dust and water smoke effectively, guaranteed oil storage lubricating condition in the bearing bore, prolonged the service life of carrying roller greatly, makes the carrying roller life-span improve 4-6 doubly.
2, because bearing seat part number reduces, and process modification people makes the weight saving of the utility model carrying roller, thereby, rotor inertia is reduced, go slick, the starting power of band conveyor is reduced thereupon.
3, adopt the extruding folding forming between bearing seat and the idler pipe, two pipe ends that make idler pipe are bent, are packaged in outside the bearing block flange end face in radially; Effectively prevent to tear conveyer belt, prolonged belt service life.
4, structure design of the present utility model makes idler pipe and bearing seat be difficult to tear open imperial, can effectively prevent the stolen of bearing.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
The mine leather belt conveyer carrying roller comprises roller carrier shaft 1 and idler pipe 5, and bearing block assembly is housed respectively in the idler pipe two ends, sees Fig. 1.
Bearing block assembly comprises bearing seat 4, bearing 2, seal ring 3 and ring washer 6.Bearing seat 4 is the flange plate-like, and seat is equipped with bearing 2, seal ring 3 and ring washer 6 in the hole successively; Bearing seat 4 flange face edges are provided with the arc limit of turning up.Seal ring 3 is a multilayer words urethane seal circle.
Two pipe ends of idler pipe 5 are bent, are packaged in outside bearing seat 4 flange faces in radially.
4 hole depths of bearing seat are the 30-45 millimeter.
