The rotation shaft of the furnace pipe is provided with a furnace pipe tray; the furnace pipe tray is supported by a riding wheel; the riding wheel is sleeved on a bearing shaft; and the bearing shaft is fixed and installed on the shell of the rotary furnace. The device is characterized in that the middle of the furnace pipe tray is provided with a tray flange; the two sides of the furnace pipe tray are retractive tray supporting edge surfaces; the riding wheel is composed of two bearings B and a gasket which is clamped between the two bearings B and has a diameter less than diameters of the two bearings B; the tray flange arranged in the middle of the furnace pipe tray is moveably sleeved between the two bearings B, and the thickness of the tray flange is slightly smaller than that of the gasket; the tray flange is not contacted with the two bearings B and the middle gasket; the bearing outer rings of the two bearings B are respectively contacted with the tray support edge surfaces at the two sides of the furnace pipe tray; the retractive tray supporting edge surfaces at the two sides of the furnace pipe tray are respectively matched with the bearing outer rings of the two bearings B; and the two bearings B are 309 bearings. The utility model has the advantage that a safe, reliable and durable furnace pipe riding wheel device of an inclined drum type resistance rotary furnace is provided.
Description
Technical field
The utility model relates to a kind of flue riding wheel apparatus, but particularly a kind of tilting roller-type resistance rotary furnace flue riding wheel apparatus.
Background technology
" the RGD 45 type tilting-type rotary furnaces " but of the dynamo-electric head factory production of tilting roller-type resistance rotary furnace such as Jiangsu Science & Engineering Univ. at present and Changxing, Zhejiang Province county are just reaching " RG series drum-type gas carbruizing furance " that electric furnace factory produces.Be mainly used in heat treatments such as gas carburizing, carbo-nitriding and bright quenching to miniature parts such as bicycle, sewing machine, standard component, bearing steel ball, roller and chains.
Wherein the major function of flue support roller is to support flue pallet and flue rotating shaft further to hold whole flue.As shown in Figure 1: but in the flue rotating shaft 4 of tilting roller-type resistance rotary furnace flue 2 flue pallet 3 is housed, and flue pallet 3 is supported by support roller 6.Support roller 6 intermediate sleeve are contained on the bearing A8.Bearing A8 is sleeved on the bearing shaft 7, and bearing shaft 7 is fixedly mounted on the rotary furnace shell 1.In the middle of the support roller 6 is support roller groove 9.Pallet outer ring 5 cooperations of flue pallet 3 are installed in the support roller groove 9 in the middle of the support roller 6.Described bearing A8 is 206 ball bearings, and this bearing A8 bearing load power is little, is easy to damage.The stress point of flue pallet 3 is merely pallet outer ring 5, and pallet outer ring 5 only contacts with support roller groove 9, support roller groove 9 play support flue pallet 3 and with the effect of flue pallet pivoting friction.Support roller groove 9 contact-making surfaces are easy to damage and skid.Above-mentioned in a word flue riding wheel apparatus poor stability, service life is short.
Summary of the invention
But the purpose of the utility model provides a kind of flue riding wheel apparatus of safe and reliable, long-lived tilting roller-type resistance rotary furnace.
The technical scheme of the utility model is: but a kind of tilting roller-type resistance rotary furnace flue riding wheel apparatus.The flue pallet is housed in the flue rotating shaft, and the flue pallet is supported by support roller, and support roller is sleeved on the bearing shaft, and bearing shaft is fixedly mounted on the rotary furnace shell.Be characterized in: be tray flange in the middle of the flue pallet, flue pallet both sides are the tray support edge face of indentation.Support roller is reached by two bearing B and constitutes than two all little packing rings of bearing B at two bearing B therebetween one diameters.Tray flange movable set in the middle of the flue pallet is between two bearing B, and its tray flange thickness is slightly less than gasket thickness, and tray flange does not contact with both sides bearing B and intermediate gasket.The bearing outer ring of two bearing B contacts with the tray support edge face on flue pallet both sides respectively, the tray support edge face of flue pallet both sides indentation respectively with the supporting setting of the bearing outer ring of two bearing B.
Described two bearing B all select 309 bearings for use.
This flue riding wheel apparatus adopts 309 big model dual bearing structures, with the flue pallet two big contact-making surfaces is arranged.Make the support stress surface big like this, balanced surface is big, and load-bearing capacity is big.Thereby this flue riding wheel apparatus is not easy to damage long service life.
But the utility model has the advantages that provides a kind of safe and reliable, long-lived tilting roller-type resistance rotary furnace flue riding wheel apparatus.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of the former flue riding wheel apparatus of the utility model.
Fig. 2 is the structural representation of the new flue riding wheel apparatus of the utility model.
Among the figure: 1, rotary furnace shell, 2, flue, 3, the flue pallet, 4, the flue rotating shaft, 5, the pallet outer ring; 6, support roller, 7, bearing shaft, 8, bearing A, 9, the support roller groove, 10, tray flange; 11, tray support edge face, 12, packing ring, 13, bearing outer ring, 14, bearing B.
The specific embodiment
As shown in Figure 2: but a kind of tilting roller-type resistance rotary furnace flue riding wheel apparatus.Flue pallet 3 is housed in the flue rotating shaft 4, and flue pallet 3 is supported by support roller 6, and support roller 6 is sleeved on the bearing shaft 7, and bearing shaft 7 is fixedly mounted on the rotary furnace shell 1.Be characterized in: be tray flange 10 in the middle of the flue pallet 3, flue pallet 3 both sides are the tray support edge face 11 of indentation.Support roller 6 is reached by two bearing B14 and constitutes than two all little packing rings 12 of bearing B14 at two bearing B14 therebetween one diameters.Tray flange 10 movable sets in the middle of the flue pallet 3 are between two bearing B14, and the thickness of its tray flange 10 is slightly less than the thickness of packing ring 12, and tray flange 10 does not contact with both sides bearing B14 and intermediate gasket 12.The bearing outer ring 13 of two bearing B14 contacts with the tray support edge face 11 on flue pallet 3 both sides respectively, the tray support edge face 11 of flue pallet 3 both sides indentations respectively with the bearing outer ring 13 supporting settings of two bearing B14.
Described two bearing B14 all select 309 bearings for use.
