Description

Lubricating grease service life testing device Technical Field The utility model relates to the technical field of lubricating grease, in particular to a lubricating grease service life testing device. Background In the field of household appliance production, efficient operation of a motion mechanism is crucial to product performance, while lubricating grease is used as a key material for reducing friction and prolonging service life of the mechanism, and performance evaluation becomes one of core links in a product development process. Currently, the evaluation of lubricating grease in industry mainly depends on two traditional methods: The first one is a performance test method, which evaluates the viscosity, dropping point, abrasion resistance and other basic physical and chemical indexes of the lubricating grease. However, in the actual model selection process, the performance test indexes of different types of lubricating grease often show high similarity, and the actual performance of the lubricating grease under the actual working condition is difficult to effectively distinguish. Secondly, a long-term operation test method of the whole machine is adopted, and the method is used for directly observing the performance attenuation condition of the whole machine by arranging lubricating grease in the whole machine to perform full life cycle operation. Although the method can truly reflect the service life of the lubricating grease, the method has the remarkable defect that the evaluation period is extremely long, namely the complete machine operation time is required to be completely consistent with the design service life of the lubricating grease, for example, the lubricating grease with the design service life of 10 years is required to continuously operate for 10 years, which is in serious contradiction with the requirements of 'quick iteration and cycle shortening' in the product development stage, so that the traditional long-term operation test method cannot meet the model selection work in the development process at all. Disclosure of utility model The utility model aims to provide a lubricating grease service life testing device, which aims to solve the problems of long evaluation period, low evaluation efficiency and the like of the existing lubricating grease service life evaluation method. The embodiment of the utility model provides a lubricating grease life testing device which comprises a temperature control box and a lubricating grease life testing mechanism, wherein the lubricating grease life testing mechanism is arranged in the temperature control box and comprises a driving piece, a first gear, a second gear and a load component, the driving piece is in transmission connection with the first gear, the first gear is meshed with the second gear, and the load component is arranged on the second gear. Further, the second gear is horizontally arranged, and the load assembly is vertically installed on the second gear.
