Trough conveyor head gear ring connected to the hub

Trough conveyor head gear ring of improved 2020 - connected to the hub 10 - 28 good grasp sun eight tiger Duan Jianning ( Wei cement co. , LTD. ) A company of 2500 t/d production line put into operation in August 2007, clinker conveying device is SCD800 & times; 110642 mm tank conveyor, the aircraft horizontal distance 91455 mm, hoisting height 48400 mm, transport capacity of 115 t/h ( Normal) 、175t/h( The largest) 。 For easy to wear head round, in order to facilitate maintenance and replacement, sprocket can be divided into gear ring and the wheel, gear ring part is divided into 5 fan-shaped gear block, each tooth piece with five bolts connected to the hub ( See figure 1) 。 The bolt connection is used a pair of inner and outer taper sleeve design, its role is to protect the connection hole, hole to avoid the wear and tear caused by the sprocket scrap. Figure 1 conveying the nose gear ring and wheel hub for connection to the change of structure in early 2010 equipment inspection before found the reducer side gear ring individual connection bolt, by parking examination found that most of the inner and outer taper sleeve and connection hole wear serious, tooth individual pieces will fall off. Reducer side is in good condition. Through analysis, as a result of the inner and outer taper sleeve lhe swelling quantity is limited, and the stress of the gear ring and heavier, especially in the speed reducer, chain and outgoing thrust on the tooth block. After long time running, taper sleeve will appear different degree of wear and tear. Through research, the company canceled the hub connected to the tooth piece of lhe swelling taper sleeve, only keep bolts ( See figure 2) 。 Bolt for self-control, the dimensions of the polished rod depends on the connecting hole diameter, threaded portion for M36. Bolt connecting holes for transition fit, the polished rod and the bolt with a hammer knock gently into the hole. Gasket thickness 5 mm and self-control. The locking bolt adopts double nut loose prevention measures. After transforming equipment smooth operation, the effect is good.
