Embodiment Construction

[0013] like figure 2 Shown: a tilting drum-type resistance rotary furnace furnace furnace supporting wheel device. Furnace receptacle tray 3 is housed on furnace revolving shaft 4, and furnace receptacle tray 3 is supported by supporting wheel 6, and supporting wheel 6 is sleeved on the bearing shaft 7, and bearing shaft 7 is fixedly installed on the rotary furnace shell 1. Its characteristics are: the center of the furnace tray 3 is a tray flange 10, and the two sides of the furnace tray 3 are indented tray support edges 11. Supporting wheel 6 is made of two bearings B14 and a washer 12 with a diameter all smaller than two bearings B14 sandwiched in the middle of two bearings B14. The pallet flange 10 in the middle of the furnace pallet 3 is movable between two bearings B14, and the thickness of its pallet flange 10 is slightly less than the thickness of the washer 12, and the pallet flange 10 does not contact with both sides bearings B14 and the middle washer 12. The bear...

Abstract

The invention provides an internal furnace riding wheel device of a titling drum-type resistance rotary furnace. An internal furnace tray is installed on a rotating shaft of the internal furnace and is supported by a riding wheel, the riding wheel is sleeved on a bearing axis and the bearing axis is fixedly installed on a rotary furnace shell. The device is characterized in that the middle of theinternal furnace tray is a tray flange, both sides of the internal furnace tray are retractive tray support edge surfaces, the riding wheel is composed of two bearings B and a washer sandwiched between the two bearings, wherein the diameter of the washer is smaller than that of each bearing B; the tray flange in the middle of the internal furnace tray is flexibly sleeved between the two bearings B, the thickness of the tray flange is slightly less than that of the washer, the tray flange does not contact with the two bearings B and the middle washer; the bearing outer rings of the two bearings B are respectively contacted with the tray support edge surfaces on the two sides of the internal furnace tray, the retractive tray support edge surfaces on the two sides of the internal furnace tray are respectively matched with the bearing outer rings of the two bearings B; and the two bearings B adopt 309 bearings. The advantage of the invention lies in providing a safe and reliable and durable internal furnace riding wheel device of the titling drum-type resistance rotary furnace.

Description

technical field [0001] The invention relates to a furnace tank supporting wheel device, in particular to a tilting drum type resistance rotary furnace furnace tank supporting wheel device. Background technique [0002] At present, the tilting drum type resistance rotary furnace is "RGD45 type tilting rotary furnace" produced by Jiangsu University of Science and Technology Electromechanical General Factory and the "RG series drum type gas carburizing furnace" produced by Zhengda Electric Furnace Factory in Changxing County, Zhejiang Province. It is mainly used for heat treatment such as gas carburizing, carbonitriding and smooth quenching of small parts such as bicycles, sewing machines, standard parts, bearing steel balls, rollers and chains. [0003] Among them, the main function of the furnace support wheel is to support the furnace tray and the furnace shaft to further support the entire furnace. like figure 1 Shown: the furnace inner tray 3 is housed on the inner furna...
