The double-line contacting phenomenon in double-enveloping cycloid planetary transmission with floating plate is favorable to improve the load capacity

the lubricating property and the transmission precision.Based on a brief introduction of the structure and transmission principle of this new transmission form

the physical prototype is trial-produced.The experiment on the physical prototype of double-enveloping cycloid planetary transmission with floating plate are conducted by using the digital auto-collimator

the polygon and the grating.The experiments include measurement of transmission error

backlash and torsional stiffness.Then the experiment data are analyzed and processed.The experiment result shows that the double-enveloping cycloid planetary transmission with floating plate device has the higher transmission precision and higher torsional stiffness

but lower backlash.
