Suspension apparatus of screw conveyer

Abstract

The invention discloses a suspension apparatus of a screw conveyer. The suspension apparatus of the screw conveyer comprises a connecting flange shaft which is used for connecting two rotating shafts and a bearing seat which is arranged on the connecting flange shaft. A bearing is arranged between the connecting flange shaft and the bearing. Each rotating shaft is further provided with two glands. The two glands are respectively arranged on two sides of the bearing seat. A seal component is arranged between each gland and each rotating shaft. The seal component comprises a hair felt ring and an oil seal. The hair felt ring and the oil seal are arranged in sequence from inside to outside. The oil seal is a J-shaped frameless rubber oil seal. The suspension apparatus of the screw conveyer is capable of preventing dust from entering into the bearing seat and preventing lubrication materials in the bearing seat from leaking outwards, guarantees a good lubrication state in the bearing seat, avoids bearing abrasion, fissures producing and breaking, is long in service lift, is free from frequent production halts, overhauling and exchanging and increases production efficiency.

Description

technical field [0001] The invention relates to a suspension device, in particular to a suspension device used in a screw conveyor. Background technique [0002] The screw conveyor is a kind of transportation equipment widely used in chemical, food, cement and other industries, and the suspension device is one of its components, which is used to lift the rotating shaft. The existing suspension device structure is as attached figure 1 As shown, it includes a connecting flange shaft 2 connecting two rotating shafts 1 and a bearing seat 3 installed on the connecting flange shaft 2 , and a bearing 4 is provided between the connecting flange shaft 2 and the bearing seat 3 . During use, it was found that the bearings were severely worn and had a short service life, and some even cracked and broke, requiring frequent shutdowns for maintenance and replacement, which seriously affected production. The cause of bearing wear and cracks and breakage is: due to the harsh working enviro...

AI Technical Summary

Problems solved by technology

In the process of use, it was found that the bearings were severely worn, the service life was short, and some even cracked and broken, requiring frequent shutdowns for maintenance and replacement, which seriously affected production

The cause of bearing wear and cracks and breakage is: due to the harsh working environment, the suspension device works in dust, and the dust will cause poor lubrication after entering the bearing seat, resulting in serious wear of the bearing, and even cracks and breakage
