Abstract

The utility model discloses a transversely moving sliding wheel. The transversely moving sliding wheel is composed of a sliding wheel body, a sliding wheel shell, an inner gland, an outer gland, a lubricating oil way, a sliding wheel shaft, a positioning sleeve, a framework oil seal and a steel copper sleeve. The positioning sleeve is installed between the outer gland and the sliding wheel shaft and makes contact with the outer side of the inner gland. A gap is reserved between the inner gland and the sliding wheel shaft. The transversely moving sliding wheel has the advantages that the area of the friction surface of an axial support of a sliding wheel disc is enlarged, the specific pressure of the friction surface is reduced, abrasion is reduced, the sliding wheel disc is prevented from sinking, the contact surface gap between the positioning sleeve and the inner gland can be adjusted, and the lubricating oil way and the oil seal are reasonably arranged.

Description

A kind of traversing pulley

Technical field

The utility model belongs to cutter suction dredger dredging plant technical field, especially relates to a kind of traversing pulley that dredging vessel swings of realizing.

Background technology

Cutter suction dredger is when ship dredging construction, by after ship's fix with the piling bar of afterbody, bow bridge is transferred to certain depth, when reamer rotation is excavated, by the traversing cable of bow, by two traversing pulleys on bridge, realize swinging of boats and ships and excavate, by the earth after excavating, by slush pump, by pipeline, be transported to assigned address.The working environment of realizing the traversing traversing pulley of boats and ships is under water, and the silt particle that dug by silt particle that traversing cable carries and reamer affects, and condition of work is very harsh; During again because of traversing pulley work, pulley disc is to approach under level to work, and very easily causes the damage of traversing pulley assembly; During because of traversing pulley work, pulley disc is horizontal, existing traversing pulley, because to pulley disc axial support, design exists defect and deficiency, cause following common damage type: sealing, pulley disc that pulley disc vertical direction sinks to destroying himself may wear to housing, pulley spindle and axle sleeve wearing and tearing or kill etc., above-mentioned situation all hinders freely rotating of pulley disc then to injure traversing cable after occurring.

Summary of the invention

The purpose of this utility model is providing a kind of and has increased the area of the rubbing surface of pulley disc axial support, is reducing rubbing surface specific pressure, reducing wear, preventing that pulley disc from sinking, adjusting the traversing pulley of contact surface gap, reasonable Arrangement lubricant passage way and the oil sealing of positioning sleeve and internal gland with improving the deficiency of prior art.

The purpose of this utility model is to realize like this, a kind of traversing pulley, by pulley body, pulley housings, internal gland, outer press cover, oil leab, pulley spindle, positioning sleeve, outside framework oil seal and steel copper sheathing form, be characterized in that positioning sleeve is arranged between outer press cover and pulley spindle and with the outer side contacts of internal gland, between internal gland and pulley spindle, leave gap.

In order further to realize the purpose of this utility model, can be that thruster gap adjustment bolt is connected with positioning sleeve through pulley housings.

In order further to realize the purpose of this utility model, can be on the pulley spindle of positioning sleeve and internal gland contact position, to be provided with the outlet of oil leab.

In order further to realize the purpose of this utility model, can be to be respectively equipped with sealing ring at internal gland and pulley body junction, positioning sleeve and pulley spindle junction, internal gland and outer press cover junction.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopt positioning sleeve to be arranged between outer press cover and pulley spindle and with the outer side contacts of internal gland, internal gland contacts with pulley spindle, increased like this area to the rubbing surface of pulley disc axial support, it is the contact area of positioning sleeve and internal gland, to reduce the specific pressure of rubbing surface, then alleviate friction and can reduce wear, can effectively prevent that pulley disc from sinking; Thruster gap is adjusted bolt and is connected with positioning sleeve through pulley housings, thruster gap is set in traversing pulley housings and adjusts bolt, after the contact surface abrasion of positioning sleeve and internal gland, by adjusting thruster gap, adjust bolt, can compensate the wearing and tearing of the contact surface of positioning sleeve and internal gland, prevent the sinking of pulley disc; On the pulley spindle of positioning sleeve and internal gland contact position, be provided with oil leab outlet, reasonable Arrangement lubricant passage way on pulley spindle, makes the contact surface of sliding bearing, positioning sleeve and internal gland between pulley and pulley spindle can obtain sufficient lubrication; At internal gland and pulley body junction, positioning sleeve and pulley spindle junction, internal gland and outer press cover junction, be respectively equipped with sealing ring, make the space of pulley motion part obtain positiver sealing and can enter this space by anti-sealing.
