Description

A kind of impact idler

Technical field

This utility model patent is related to a kind of carrying roller, especially the impact idler of a kind of high intensity, high leakproofness.

Background technology

Carrying roller is one of critical piece on ribbon conveyer, and the effect of carrying roller is support belt, reduces running resistance, And the sag of conveyer belt is made less than certain limit, to ensure conveyer belt even running.Carrying roller accounts for the 30%- of main screw lift 40%, because large number of, the quality of carrying roller directly influences normal operation and the running cost of conveyer, and carrying roller is described as defeated Send " heart " of machine.Main load bearing element is bearing in carrying roller, and bearing quality directly affects carrying roller performance and life-span.Bearing block It is for supporting positioning bearing, bearing block that bearings are positioned at the supporting ＆ stablizing of the two ends of roller, bearing block and roller Property directly affect the relative tram of bearing, bearing block will ensure carrying roller operationally, tie under high rotating speed, high pressure effect Structure stable performance, the quality of roller can also directly affect the service life of carrying roller, and the intensity of roller can affect bearing The service life of seat and bearing, roller high pressure, it is high-revolving in the case of be easily deformed, damaged, insufficient strength, and existing Roller in it is defective for the sealing structure of bearing block, sealing property is bad, due to the working environment of carrying roller it is complicated, outside powder Dirt or water can be entered in bearing, cause bearing service life low.

Impact idler is used to slow down impact of the blanking to conveyer belt at ribbon conveyer material feeding, mainly for coal washery, Jiao The class carrying roller changed the corrosive atmospheres such as factory, chemical plant and develop, the toughness that itself has is more than 10 times of common metal, Life-span is five times of conventional post footwear, corrosion-resistant fire-retardant, antistatic, from heavy and light the features such as, be widely used in mining.Carrying roller roll body Special macromolecular material, its mechanical performance has good wearability similar to bronze, tool, and with good self lubricity Can, do not hinder belt.Impact idler antiseptic property is superior.Roll body and sealing member all make of macromolecular material, corrosion-resistant.In corrosion Property occasion is used, and service life can reach more than 5 times of common carrying roller.

Utility model content

For the problems of the prior art, the purpose of this utility model is to provide for a kind of impact idler, and the carrying roller is arranged There are two groups of labyrinth type secret structures, improve sealing property, it is ensured that the service life of bearing, and the roller and axle of the carrying roller Reinforcement structure is provided with bearing, it is ensured that the use intensity of roller, extends the service life of carrying roller.

In order to achieve the above object, the technical solution of the utility model is：

A kind of impact idler, including the roller of middle roller carrier shaft and periphery, also including roller carrier shaft and the axle at roller two ends On bearing, bearing block install bearing, for the sealing structure of sealed bearings, it is characterised in that：Described roller inner surface is equal Rib is furnished with, corresponding bearing block bottom is also equipped with bearing block rib.

Further, described sealing structure includes two groups, and respectively the first sealing group and the second sealing group are labyrinth Formula sealing structure, wherein, the first sealing group includes being sealed on first time sealing and first, and the second sealing group includes second time sealing With second on seal.

Further, between sealing in assemble first time sealing and first, seal for second time and second on seal it Between, between the first sealing group and the second sealing group leave labyrinth cavity.

Further, lubricating oil is filled in described labyrinth cavity, the lubricating oil is butter.

Compared with prior art, the structure of the impact idler that this utility model is provided is unusual, and the roller of the carrying roller is Inner surface is evenly equipped with the structure of rib, improves the intensity of roller, can carry compared with big load, and long service life is corresponding with rib Bearing block on be also equipped with bearing block rib, the two arranged crosswise, it can be ensured that its synchronous axial system, prevent relatively rotate friction Occur, and the carrying roller employs two groups of labyrinth seal structures simultaneously, and dual-seal improves sealing property, eliminates close Packing, saves part, and extends the service life of carrying roller.
