Problems solved by technology
[0003] Plastic is a new type of material for gears. Due to the limitation of processing technology, the processing technology of injection molding is generally adopted, so that the internal structure is not as stable as metal gears, and there is currently no set of international measurement standards that can be used.
The traditional device for measuring planetary gear reducers has low precision and poor automation, and is usually too dependent on manpower to complete. Such experimental results are highly subjective and cannot objectively evaluate the mechanical properties of the plastic gear itself.
In addition, there is currently no experimental device that evaluates the strength of plastic gears by considering the plastic gear planetary reducer as a whole.

Description
technical field [0001] The invention relates to an experimental device for measuring the mechanical properties of a plastic gear planetary reducer, which belongs to the fields of precision test and measurement technology, precision instruments and mechanical transmission. Background technique [0002] Planetary gear reducer, as an essential universal component for connecting and transmitting power in mechanical equipment, has been widely used in the field of mechanical transmission. Due to the rapid development of the polymer synthesis industry, plastics have become a new material for making gears. The planetary gear reducer composed of plastic gears has the characteristics of low cost, easy processing, low noise and light weight, and is used in many aspects such as automobiles, toys and smart homes. Therefore, planetary reducers using metal gears are gradually replaced by planetary reducers with plastic gears. [0003] Plastic is a new type of material for gears. Due to t...
