Description

Technical Field

[0001] The utility model relates to the technical field of reducer tests, in particular to a novel air guiding connection ring for a test bench of a reducer assembly. Background Art

[0002] Most of the existing connection ring toolings for reducer assemblies are in a semi-sealed form. During assembly, their front surfaces are closely attached to the installation surface of the reducer assembly, and their rear surfaces are closely attached to the master plate of the bench bracket, resulting in a sealed cavity formed inside the connection ring. When the oil temperature inside the reducer assembly is relatively high, especially for a reducer assembly with a dummy motor housing, the high temperature will cause the pressure in the sealed space inside the connection ring to increase, damaging the oil sealing components of the reducer assembly. In the past, in order to prevent the internal pressure of the connection ring from increasing during individual high oil temperature tests, it was usually adopted to break and groove for air guiding at the joint surface between the connection ring and the reducer assembly, which has the following disadvantages: (1) After grooving, the universality of the connection ring tooling is damaged; (2) After grooving, the sealing performance of the connection ring tooling is damaged, and oil leakage will occur in some open tests; (3) Damaging the connection ring will increase the tooling cost of the project. Therefore, a novel air guiding connection ring that does not need to damage the connection ring and has both sealed conditions and air guiding functions is required. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above deficiencies in the prior art, and aims to provide a novel air guiding connection ring that does not need to damage the connection ring and has both sealed conditions and air guiding functions.

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

One side of the ring body is provided with an annular first joint surface and a second joint surface, and the other side of the ring body is provided with an annular third joint surface and a fourth joint surface; both the first joint surface and the second joint surface protrude from the surface of the ring body, the second joint surface is located outside the through hole in the middle of the ring body, the first joint surface is located outside the second joint surface, and an oil storage groove is arranged on the first joint surface, and the oil storage groove communicates with the annular space between the first joint surface and the second joint surface; the fourth joint surface is arranged outside the through hole and recesses into the surface of the ring body; the third joint surface protrudes from the surface of the ring body and is located outside the first joint surface, and a shaft hole passing through the first joint surface, the ring body and the third joint surface is arranged at the edge of the ring body, and a concave platform is formed between the third joint surface and the shaft hole.
