Abstract
The utility model relates to an underslung bearing, which is characterized in that the underslung bearing consists of a left and a right symmetrical suspension arm which are connected together through bolts; wherein the underside of the underslung bearing is provided with an axle hole where a bearing shell is installed, a center hole is axially arranged in the underslung bearing, a grease way and a gland strip are arranged in the center hole, and the top of the grease way is connected with the mounting hole of nozzle tip. The utility model has the advantages that: when the bearing shell of the underslung bearing has severe abrasion, only the bearing shell of the underslung bearing needs replacing, with no need to replace the overall underslung bearing; if the underslung bearing needs replacing, the underslung bearing can be directly dismounted, installed or maintained from the conduit maintenance hole without disassembling the delivery conduit; in this way, the utility model is not only convenient for maintenance and installation of the underslung bearing but also labor saving and time saving, with reduced construction cost for users.
Description
Technical field
The utility model belongs to the conveying machinery equipment technical field, particularly relates to a kind of underslung bearing that is used for fixing the helical feed arbor that supports the loading and unloading bulk cargo.
Background technology
At present; the colliery; the exploitation of all kinds of metallic ores and the concrete mixing plant in the building engineering all adopt underslung bearing that conveyor shaft is captiveed joint with delivery duct with conveyor screw; this underslung bearing is to adopt top for hanging arm; the bottom is that the two-part structure up and down of hanging FE Tiler also forms with screw is fastening; hanging arm and hanging the FE Tiler position that contacts and have axis hole; because conveyor shaft directly contacts with the axis hole of underslung bearing; and the working environment of above-mentioned underslung bearing is under the dust operating mode; can enter dust granules or impurity between conveyor shaft and the underslung bearing like this; and then make between conveyor shaft and the underslung bearing and to produce excessive abrasion; will influence the normal use of conveyer when this abrasion is serious, thereby need to change underslung bearing.And existing underslung bearing is the aluminum making, and its manufacturing cost is higher, and often changing underslung bearing has just increased user's executive cost; Bring certain burden to the user; In addition because delivery duct is its mechanical strength of assurance, its service ports design-calculated is smaller generally speaking, when needs repair or replace underslung bearing, under the situation of not taking delivery duct apart, the maintainer is difficult to underslung bearing is installed to the fixed position, so cause maintenance and change very inconvenience, and effort, time-consuming.
Summary of the invention
The utility model provides a kind of simple in structure, with low cost and underslung bearing that is used for fixing the helical feed arbor that supports the loading and unloading bulk cargo of being convenient to keep in repair and change for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
Underslung bearing, it is characterized in that: it is that the arm of hanging by left and right two parts symmetry constitutes by screw is fastening, be provided with axis hole in the underslung bearing bottom, bearing shell is installed in the axis hole, underslung bearing axially is provided with centre hole, be provided with oil leab and sealing band in this centre hole, the oil leab top is connected with the oil nozzle mounting hole.
The utility model can also adopt following technical measures:
Described bearing shell outer wall is provided with positioning boss, and the position of the inboard corresponding bearing shell positioning boss of the axis hole of underslung bearing has the positioning groove that is complementary with positioning boss, to prevent to hang arm and bearing shell generation slip and friction.
The described two outer extensions of hanging arm are provided with and charging line bonded assembly screw.
Described bearing shell is the self-lubricating modified nylon materials bearing shell of once injection moulding.
Described two to hang arm be that cast iron materials is made.
Advantage and the good effect that the utlity model has are: because the utility model is designed to left and right two parts symmetrical structure with underslung bearing, and in the bearing hole of its underpart, be embedded with the self-lubricating modified nylon materials bearing shell of once injection moulding, when severe wear appears in the bearing shell of underslung bearing, the bearing shell that only needs to change underslung bearing just can, need not to change whole underslung bearing; If need to change underslung bearing, under the situation of not taking delivery duct apart, can directly dismantle, install or keep in repair underslung bearing from the pipeline maintenance mouth, so not only be convenient to the maintenance and the installation of underslung bearing, and laborsaving saving time; Also can be the user simultaneously and reduced construction cost.

Among the figure: 1, hang arm; 2, bearing shell; 3, sealing band; 4, screw; 5, oil nozzle mounting hole; 6, oil leab; 7, positioning boss; 8, tightening screw.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, underslung bearing, it is that the arm 1 of hanging by left and right two parts symmetry constitutes by tightening screw 8 is fastening, is provided with axis hole in the underslung bearing bottom, and the self-lubricating modified nylon materials bearing shell 2 of once injection moulding is installed in the axis hole.Underslung bearing axially is provided with centre hole, is provided with oil leab 6 and sealing band 3 in this centre hole, and oil leab 6 tops are connected with oil nozzle mounting hole 5.Described bearing shell 2 outer walls are provided with positioning boss 7, the position of the inboard corresponding bearing shell positioning boss of the axis hole of underslung bearing has the positioning groove that is complementary with positioning boss, realize bearing shell 2 and 1 the location of hanging arm by this positioning boss and positioning groove, can avoid hanging arm and bearing shell like this and produce slip and friction.The described two outer extensions of hanging arm are provided with and charging line bonded assembly screw 4, realize captiveing joint of underslung bearings and delivery duct by screw 4.Described two hang arm 1 makes for cast iron materials, can reduce the manufacturing cost of underslung bearing like this, and saves executive cost for the user.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
