Problems solved by technology

In this way, not only the additional workload of on-site maintenance of the scraper conveyor is large, but also other undamaged parts of the sprocket have to be replaced accordingly; moreover, due to the precise coordination between the bearing and the shaft, the bearing is often disassembled, causing new losses

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] like figure 1 Shown, the present invention is made up of left bearing block 1, left sprocket wheel 2, main shaft 3, right sprocket wheel 4, right bearing seat 5, half coupling 6 etc. The left bearing seat 1, the main shaft 3, the right bearing seat 5, and the half-coupling 6 form a drive shaft system, and the half-coupling 6 transmits an external driving force to drive the main shaft 3 to rotate.

[0014] like figure 2 , 3 Shown, left chain wheel 2 and right chain wheel 4 have wheel hub 21, belt gear hub 22, alignment pin 23, wheel hub connection bolt 24, wheel hub and belt gear edge connection bolt 25 and form. Both the hub 21 and the gear rim 22 are split structures, and the half gear rim 22 is fastened on the hub 21 with connecting bolts 25 between the hub and the gear rim. The hub 21 is divided into two halves along the centerline, and the half hub 21 i...

Abstract

The invention discloses a combined type chain wheel head wheel set and solves the problem of large additional workload of field maintenance of a conventional device. The combined type chain wheel head wheel set is characterized in that a left chain wheel as well as a right chain wheel comprises a hub, a toothed hub, a positioning pin, a hub connecting bolt, a hub and toothed flange connecting bolt; both the hubs and toothed flanges adopt separated structures; the toothed flanges are fastened on the hubs through connecting bolts; and the hubs are mounted on a main shaft through the positioning pins and the hub connecting bolts. According to the invention, the chain wheels comprise the hubs and the toothed flanges; both the hubs and the toothed flanges adopt separated structures; when the chain wheels are worn, all that is needed is to replace the worn toothed flanges, so that consumption of material is reduced; and the combined type chain wheel head wheel set has the advantages of convenience in mounting and dismounting, small workload, shorter maintenance time and low maintenance cost, and reduces the possibility that other pieces are damaged due to replacement of the chain wheels.

Description

technical field [0001] The invention relates to a head wheel set, more specifically to a head wheel set using a scraper conveyor. Background technique [0002] There are two sprockets on the head wheel set of the scraper conveyor, and the rotation of the sprockets drives the circular chain to pull the scraper to run to realize material transportation. During work, the rotating teeth of the sprocket drive the round link chain, which has a large pulling force and severe wear and tear. When the gear teeth are severely worn, the gap increases, the ring chain will swing in the gear teeth, and the scraper machine does not operate normally. At this time, although other parts are in good condition, the sprocket needs to be replaced. It needs to be replaced almost every month in daily production. The traditional sprocket has an integral structure. When replacing it, the head of the scraper machine must be disassembled, the head wheel set is removed from the head bracket as a whole,...
