Abstract
The utility model discloses an external type head wheel set transmission device used for a heavy-duty scrapper. The external type head wheel set transmission device used for the heavy-duty scrapper comprises two groups of bearing seats, wherein the two groups of bearing seats are installed with a machine head rack of the heavy-duty scrapper through fasteners, bearings are arranged in the two groups of bearing seats, the bearings are sleeved on a chain wheel shaft, transmission chain wheels are arranged on the chain wheel shaft, the transmission chain wheels are arranged outside the machine head rack, the chain wheel shaft penetrates through the machine head rack, and the bearing seats are arranged outside the machine head rack. The external type head wheel set transmission device used for the heavy-duty scrapper greatly improves tightness and reliability and prolongs the service life of the bearings.
Description
Technical field
The utility model relates to a kind of scrapper conveyor, especially relates to a kind of heavy type scratch board machine external great wheel group driving device.
Background technology
Scrapper conveyor is a kind of in the rectangular cross section housing of sealing, carry the continuous transport equipment of bulk material by means of moving flight chain, be widely used in the industries such as metallurgy, building materials, electric power, chemical industry, cement, harbour, harbour, coal, mine, grain and oil, food and feed.In the heavy type scratch board head wheels bearing block structure in the prior art, bearing seat directly link to each other with the headstock side plate or bearing seat pedestal itself as the part of headstock, because oil sealing is direct and coal stream end in contact, be easy to damage, coal dust is easy to enter in the bearing, has greatly affected service life.And now coal preparation plant's scrapper conveyor freight volume is large, and this is very high to reliability requirement just.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of heavy type scratch board machine external great wheel group driving device, the service life of greatly having improved leak tightness, reliability and bearing.
For solving the problems of the technologies described above, the technical solution of the utility model is: heavy type scratch board machine external great wheel group driving device, comprise two groups of bearing seats that are installed together by the headstock of fastener and described heavy type scratch board machine, be equipped with bearing in the two described bearing seats, described bearing carrier ring is located on the sprocket shaft, on the described sprocket shaft driving chain wheel is installed, described driving chain wheel is arranged at the inboard of described headstock, described sprocket shaft passes described headstock, and described bearing seat is arranged at the outside of described headstock.
Preferably, described bearing seat comprises pedestal and end cap, is provided with described bearing between described pedestal and the end cap, is provided with oil sealing between described bearing and the end cap.
Preferably, be arranged with the bearing locating bush on the described sprocket shaft, described bearing locating bush is arranged between described bearing and the driving chain wheel, and described oil-sealing sleeve is loaded on the described bearing locating bush, is provided with concavo-convex maze trough between described bearing locating bush and the described end cap.
Adopted technique scheme, the beneficial effects of the utility model are: because the heavy type scratch board machine is arranged at the outside of headstock with the bearing seat of external great wheel group driving device, headstock easily seals, bearing seat is away from coal stream end, be difficult for contacting with coal dust, improved leak tightness and the reliability of bearing, greatly improved bearing service life, for large conveying quantity and high reliability scrapper conveyor provide guarantee.
Owing to being provided with concavo-convex maze trough between bearing locating bush and the described end cap, adopt this " labyrinth type " hermetically-sealed construction, improved the usage condition of bearing, greatly improved the leak tightness of bearing.
