Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, specifically a gear reducer for transmission equipment. Background Technology

[0002] The gear reducer is an external meshing involute helical cylindrical gear reducer manufactured according to the national professional standard ZBJ19004. Gear reducers are widely used in East my country as slewing mechanisms for tower cranes and are widely applied in metallurgy, mining, hoisting, transportation, cement, construction, chemical, textile, printing and dyeing, and pharmaceutical industries.

[0003] Because transmission equipment gearboxes need to operate continuously for long periods, they are usually cooled by fans. However, most of the airflow blown by the fan directly impacts the gearbox body, with only a small portion entering the heat sink for cooling, resulting in low overall cooling efficiency.

[0028] Example 1

[0029] See attached document Figure 1-4This embodiment of a transmission device gear reducer includes a reducer body 100, which includes an output end 110, a body, and a tail end 130. The tail end 130 is provided with an end cover 140, which has a ventilation port 141. The end cover 140 includes an outer cover 142 and an inner sleeve 143. The outer cover 142 is bolted to the tail end 130 of the reducer body 100. A fan is provided at the tail end 130 and is located inside the end cover 140. The inner sleeve 143 has a conical structure, and the output shaft of the fan passes through the inner sleeve 143. The air blown by the fan is guided through the inner sleeve 143 to the heat dissipation groove on the outer wall of the body.

[0030] In this embodiment, the inner sleeve 143 is composed of two identical conical plates 144. The tail end 130 is provided with a connecting post 131, which has a threaded hole. The conical plates 144 have through holes and are mounted on the connecting post 131 with screws.

[0031] In this embodiment, the conical plate 144 has a slot 145 on one side and a block 146 on the other side. The two conical plates 144 are connected and installed by being secured in the slot 145 by the block 146.

[0032] In this embodiment, the conical plate 144 is provided with connecting ears 147. The connecting ears 147 between two interconnected conical plates 144 fit together. The connecting ears 147 are provided with through holes. The two fitting connecting ears 147 are locked together by bolts and nuts.

[0033] In this embodiment, a guide ring 148 is provided at the port of the outer cover 142, and the airflow passing through the inner sleeve 143 changes its direction through the guide ring 148.

[0034] Working principle: The reducer body 100 is usually cooled by a fan. However, most of the airflow blown by the fan directly impacts the reducer body 100, with only a small portion entering the heat dissipation slots for cooling. The overall cooling efficiency is not high, as can be seen from the fan, the surface of the reducer body 100 is always hot. This design, however, uses an inner sleeve 143 and a guide ring 148 to redirect the airflow, ensuring that all the airflow blown by the fan enters the heat dissipation slots, resulting in higher overall cooling efficiency. During installation, the two conical plates 144 are respectively installed on the connecting column 131, with the locking blocks 146 of the two conical plates 144 engaging in the corresponding slots 145. Then, the connecting lugs 147 are tightened with bolts and nuts. Finally, the outer sleeve is fitted and locked in place. The entire installation and disassembly process is convenient.

[0035] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
