Description

Technical Field

[0001] The utility model relates to the technical field of mechanical driving, in particular to a worm drive device for a running-in table. Background Art

[0002] A run-in test bench is a dynamometer with a cold run-in device. It integrates the engine run-in specification execution mechanism and is a specialized test device for controlling, adjusting, and measuring operating specifications as needed. It primarily consists of a high-power traction motor and clutch, a hydraulic dynamometer loading device, a dynamometer water supply and engine cooling water supply system, fuel supply and measurement instruments, and an engine mounting stand. Depending on the engine's mounting point, specialized brackets and adjustable supports can be used to secure the engine being run-in.

[0003] Based on the engine's operating characteristics, a new or repaired engine assembly undergoes a test run to ensure that the surface condition and mechanical and physical properties of each mating component reach the required operating parameters and specifications for long-term operation. Engine run-in is generally divided into three stages: cold run-in, hot run-in, and dynamometer testing. Cold run-in involves regularly changing and increasing the speed and load of the engine's main working components, using external force as the power source and under adequate lubrication. Hot run-in uses the intact engine itself as the power source, regularly changing the speed and increasing the load while operating until the rated power and speed are achieved. Dynamometer testing measures the engine's specific fuel consumption and power at rated speed to gauge the quality of the engine's assembly, manufacturing, or repair.

[0004] At present, there are many running-in tables in mechanical production. However, many running-in tables can only process specific materials, and the flexibility and applicability of the equipment are not good enough. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content
