AI Technical Summary

Technical Problem

Under high load conditions, the lubricating oil of traditional sprocket components is difficult to take away heat in time, resulting in an increase in the temperature in the sprocket cavity, damage to the floating seal, increasing the risk of oil leakage, and adversely affecting the life of the O-ring.

Method used

An end cap assembly with a cooling pipe structure is designed to flow cooling water through the heat dissipation pipe inside the sprocket by connecting it with an external cooling water pipe, taking away heat and reducing the temperature in the sprocket cavity.

Benefits of technology

Effectively reduce the temperature in the sprocket cavity, extend the service life of floating seals and O-rings, reduce the risks of oil seepage and oil leakage, and improve equipment stability.

Abstract

The utility model relates to the technical field of coal mine fully mechanized coal mining face conveying, in particular to a chain wheel assembly cooled by cooling water. The chain wheel assembly cooled by the cooling water is structurally characterized by comprising an end cover, a positioning ring, a bearing seat, a bearing, a floating seal ring assembly, a chain wheel, a positioning ring I, a chain wheel, an O-shaped ring, a chain wheel shaft, a positioning ring II, a transparent cover, packing, a positioning pin, a check ring, a positioning ring III, a floating seal seat, a spacer bush, a positioning sleeve I, a positioning sleeve II, a blocking cover, other connecting pieces and the like. The radiator structure is additionally arranged at the position of the end cover and is externally connected with the cooling water pipeline, so that the cooling water takes away the temperature in the chain wheel assembly, and the service life of the floating seal and the O-shaped ring is prolonged. And the possibility of oil leakage and oil leakage caused by the failure of the floating seal and the O-shaped ring is reduced, so that the stability of equipment is improved.
