Abstract
The utility model relates to a suspension bearing device for a screw conveyer, comprising a connection shaft, a suspension bearing block, an oil orifice, a bearing, and sealing rings; wherein, the suspension bearing block is arranged outside the connection shaft, the suspension bearing block is provided with the oil orifice communicated with an inner part and an outer part of the suspension bearing block, the bearing is arranged in the suspension bearing block, the sealing rings are arranged at two ends of the bearing in the suspension bearing block, and the bearing is a felt bearing. According to the suspension bearing device for the screw conveyer in the utility model, the felt bearing is in elastic contact with the connection shaft, thus a good wear-resisting property is achieved; the felt bearing can rapidly expand with the action of lubricating oil, and the felt bearing plays a sealing role by itself, thereby effectively preventing cement powder from entering into the felt bearing; after a long-term operation, a layer of oil film is formed between the connection shaft and the felt bearing, so that even if the cement powder enters into the felt bearing, the felt bearing can not be destroyed, thus the felt bearing may have a long service life; therefore, the suspension bearing device has the advantages of prolonging a part replacing period, reducing frequency for shutting down to replace the bearing, reducing labor intensity of workers, reducing production cost, and raising economic benefit.
Description
Technical field
The utility model relates to a kind of conveyor screw suspension bearing device, relates in particular to a kind of suspension bearing device that is used to carry the conveyor screw of cement powders.
Background technology
Existing conveyor screw suspension bearing device; Shown in accompanying drawing 1; Comprise adapter shaft 1, hanging axis bearing 2, oilhole 3, plain bearing 4 and seal ring 5, adapter shaft 1 is outer to be provided with suspension bearing seat 2, has on the hanging axis bearing 2 to be communicated with the inside and outside oilhole 3 of said hanging axis bearing 2; Be provided with plain bearing 4 in the hanging axis bearing 2, in the hanging axis the bearing 2 and two ends that are positioned at plain bearing 4 are provided with seal ring 5.Adapter shaft 1 is used to connect two screw shafts, because plain bearing 4 is because wear resisting cast iron or copper are made, itself and being connected to of adapter shaft 1 are rigidly connected; Wearing and tearing are very fast, after cement powders is entered hanging axis bearing 2 in addition, can aggravate the wearing and tearing of plain bearing 4; Usually just must change after using a period of time; The general replacement cycle is 4～5 months, has increased productive costs and has also caused unnecessary shutdown simultaneously, has increased working strength of workers.
The utility model content
The utility model purpose is that short conveyor screw suspension bearing device of a kind of bearing replacing cycle is provided for the deficiency that overcomes prior art.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of conveyor screw suspension bearing device, comprise adapter shaft, hanging axis bearing, oilhole, bearing and seal ring, and said adapter shaft is provided with the suspension bearing seat outward; Have on the said hanging axis bearing and be communicated with the inside and outside oilhole of said hanging axis bearing; Be provided with bearing in the said hanging axis bearing, in the said hanging axis bearing and the two ends that are positioned at bearing are provided with seal ring, and said bearing is the felt bearing.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The conveyor screw suspension bearing device of the utility model, because bearing is the felt bearing, felt bearing and adapter shaft are Elastic Contact, wear resisting property is good; Simultaneously, the felt bearing can prevent that effectively cement powders from getting into the felt bearing because the effect of lubricating oil is expanded rapidly, and himself plays sealing function; In addition, through long-term operation, formed one deck oil film between adapter shaft and felt bearing; Also can not destroy the felt bearing even cement powders gets into the felt bearing, long service life has prolonged the part exchanging cycle; Reduced and shut down the number of times of changing bearing; Alleviate working strength of workers, reduced productive costs, improved economic benefit.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of the conveyor screw suspension bearing device of prior art;
Accompanying drawing 2 is the structural representation of the conveyor screw suspension bearing device of the utility model;
Wherein: 1, adapter shaft; 2, hanging axis bearing; 3, oilhole; 4, plain bearing; 5, seal ring; 6, felt bearing.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of conveyor screw suspension bearing device of the utility model shown in accompanying drawing 2; Comprise adapter shaft 1, hanging axis bearing 2, oilhole 3, felt bearing 6 and seal ring 5; The said adapter shaft 1 outer suspension bearing seat 2 that is provided with; Have on the said hanging axis bearing 2 and be communicated with the inside and outside oilhole 3 of said hanging axis bearing 2, be provided with felt bearing 6 in the said hanging axis bearing 2, in the said hanging axis the bearing 2 and two ends that are positioned at felt bearing 6 are provided with seal ring 5.
Before the use, at first in oilhole 3, inject lubricating oil, felt bearing 6 can prevent that effectively cement powders from getting into the felt bearing because the effect of lubricating oil is expanded rapidly, and himself plays sealing function; Simultaneously, felt bearing 6 is an Elastic Contact with adapter shaft 1, and wear resisting property is good; In addition, through long-term operation, 6 on adapter shaft 1 and felt bearing have formed one deck oil film; Also can not destroy felt bearing 6 even cement powders gets into the felt bearing, long service life has prolonged the part exchanging cycle; Reduced and shut down the number of times of changing bearing; Alleviate working strength of workers, reduced productive costs, improved economic benefit.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
