Description

Technical Field

[0001] The utility model relates to the technical field of coal mining machines, in particular to a cooling structure of a rocker arm planetary mechanism of a coal mining machine. Background Art

[0002] The rocker arm is an important part of the coal mining machine. It is responsible for transmitting the torque of the cutting motor to the drum and adjusting the height of the drum. As a key component of the coal mining machine for cutting coal, the reliability of the rocker arm directly affects the working efficiency of the coal mining machine. The coal mining machine works in harsh conditions, with heavy cutting loads. The planetary mechanism is prone to high temperatures. Excessive temperature can cause many problems such as reduced lubricating oil performance, reduced rigidity of related parts, and oil leakage at the seal, causing failure of key components such as gears, bearings, and oil seals, resulting in damage to the planetary reduction mechanism.

[0003] In the prior art, a Chinese patent document with a publication number of CN212803212U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a cooling structure of a planetary mechanism of a rocker arm of a coal mining machine, comprising a cooling water jacket, a water inlet channel connected to the cooling water jacket and a water outlet channel connected to the water inlet channel, and a water inlet joint connected to the water inlet channel and a water outlet joint connected to the water outlet channel, wherein the water inlet joint and the water outlet joint are arranged on the housing of the rocker arm, and a spray head is arranged on the housing of the rocker arm, wherein the cooling water jacket is arranged on the outer wall of the inner gear ring in the planetary mechanism, and a cooling water circulation channel is arranged between the inner wall of the cooling water jacket and the outer wall of the inner gear ring, wherein the cooling water circulation channel is an arc-shaped channel, wherein the arc is a superior arc, and the water outlet joint is connected to the spray head. The utility model has a simple structure, solves the heating problem of the planetary mechanism of the rocker arm of the coal mining machine, and improves the service life of the rocker arm of the coal mining machine.

The existing technology uses a cooling water jacket to reduce the temperature. However, the cooling effect of a single cooling water jacket is not obvious, and high temperature warning cannot be performed, which leads to a limited cooling range, low cooling effect, and the inability to shut down the machine in time for protection when high temperature occurs.
