Lift-adjustable elliptical double-ring track soil tank test bench

Abstract

The invention, which belongs to the field of scientific research devices, provides an elliptical double-ring-orbit soil box test bench with the characteristic of adjustable lifting. An elliptical inner orbit with an outer elliptical gear ring and an elliptical outer orbit with an inner elliptical gear ring are installed at a lifting adjusting rack assembly. A rack seaming unit is installed at theelliptical inner orbit and the elliptical outer orbit based on supporting by inner and outer support rollers; a test component drive motor, a rack seaming travel drive motor, a planet-wheel differential mechanism assembly, an inner direction-changing transmission case, an outer direction-changing transmission case, an inner worm-gear reducing direction-changing transmission case, and an outer worm-gear reducing direction-changing transmission case are installed at the rack seaming unit; the planet-wheel differential mechanism assembly is connected with the inner direction-changing transmissioncase and the outer direction-changing transmission case respectively by an inner semiaxis and an outer semiaxis; and an inner drive gear and an outer drive gear are installed at power output shafts of the inner worm-gear reducing direction-changing transmission case and the outer worm-gear reducing direction-changing transmission case fixedly and respectively. The test bench has advantages of high adaptability to simulation test detection, good test continuity, high test efficiency, real and reliable test detection data, and reasonable test device occupation area.

Description

technical field [0001] The invention belongs to scientific research and test equipment, and mainly relates to an indoor simulated scientific research and test device for agricultural machinery operation parts. Background technique [0002] Due to the wide variety of agricultural operating environments, conditions and technical requirements, it is necessary to conduct tests under different conditions on various agricultural machinery operating parts on indoor simulation test equipment to provide reliable technical support for engineering design. Among all kinds of indoor soil tank test equipment, the circular soil tank type agricultural machinery test equipment has been widely used because of its small footprint and low construction investment. However, since the operating parts always move in a circle during the test and detection operation, there is a big difference from the actual operation of the agricultural machinery parts in a straight line, and the detection accuracy ...

AI Technical Summary

Problems solved by technology

However, since the operating parts always move in a circular motion during the test and detection operation, there is a big difference from the actual operation of the agricultural machinery parts in a straight line, and the detection accuracy is poor

In addition, the long-shaped soil tank test equipment adopts the linear operation mode when used in the test, but there are problems such as the large area of ​​the test equipment, high construction investment and high operating costs, and the popularization and application are limited.
