Problems solved by technology

At present, although the idler head assembly of the known belt conveyor has the characteristics of simple structure, convenient maintenance and long service life of the bearing, and some other advantages, due to structural reasons, there are still some problems in the blind head assembly of this kind of structure. This defect is prominently manifested in: poor sealing effect of the bearing, easy oil leakage, inconvenient addition of lubricating oil, difficult control of the bearing clearance, easy damage of the bearing, and low service life of the total stop of the boring head

Embodiment Construction

[0008] Install the single-row tapered roller bearing (8) and the thrust bearing (9) on both ends of the steps of the rotating shaft (6) in sequence, and install the rotating shaft (6) on the bearing housing through the single-row tapered roller bearing (8) and the thrust bearing (9) (1) In the through hole in the middle, in order to facilitate the lubrication and oiling of the bearing, an axial oil port (12) is opened at the oil port of the rotating shaft, and another through oil port (11) is opened on the rotating shaft along the vertical direction of the axis , the two oil ports intersect. Install a standard oil nozzle (5) at the oil port at the end of the rotating shaft, in order to facilitate the adjustment and pre-tightening of the bearing clearance, and also to fix the rotating shaft (6) in the bearing seat (1). The port portion of the seat (1) is positioned and installed with the gland fixing bolt (3) to install the bearing gland (2), and the upper part of the bearing g...

Abstract

The invention relates to a novel carrier roller choke plug assembly of a belt conveyer. Single-row tapered roller bearings and thrush bearings are sequentially arranged at both ends of a step of a rotating shaft; the rotating shaft is arranged in a through hole in the middle of a bearing block through the single-row tapered roller bearings and the thrush bearings; a standard oil injection nozzle is arranged at the oil opening position on the end part of the rotating shaft; a circular hole is formed in the center of a bearing gland; an annular seal ring groove in an appropriate shape is formed at the position of the circular hole; a rotating shaft seal ring is arranged in the annular seal ring groove; through the rotating shaft seal ring, a seal is formed between the bearing gland and the rotating shaft; an annular seal ring groove in an appropriate shape is formed on the excircle of an upper opening of the bearing gland; a bearing cavity seal ring is arranged in the annular seal ring groove; and through the bearing cavity seal ring, a seal is formed between the bearing gland and an inner cavity of the bearing block. In order to prevent dust and the leakage of lubricating oil, a bearing block plug cap is arranged at the position of the through hole at the inner end of the bearing block.

Description

technical field [0001] The invention relates to a belt conveyor idler head assembly, in particular to a new belt conveyor idler head assembly. It belongs to the technical field of belt conveyors. Background technique [0002] In the idler devices of various belt conveyors, bearings and bulkheads are required. The belt conveyor works in high dust, high temperature and open air environment, and its environment is very harsh. At present, although the idler head assembly of the known belt conveyor has the characteristics of simple structure, convenient maintenance and long service life of the bearing, and some other advantages, due to structural reasons, there are still some problems in the blind head assembly of this kind of structure. This defect is prominently manifested in: poor sealing effect of the bearing, easy oil leakage, inconvenient addition of lubricating oil, difficult control of the bearing clearance, easy damage of the bearing, and low service life of the total ...
