Planet gear speed reducer enclosed type experiment bench

Abstract

The invention discloses a planet gear speed reducer enclosed type experiment bench comprising a motor. The motor is connected with an output gear box, which is used to output torque equally by two output paths. One output path is used to output the torque to a first speed reducer by a universal joint and an installation base, and the other output path is connected with a hydraulic loader, the installation base, and a second speed reducer. The hydraulic tensioning of the first speed reducer and the hydraulic tensioning of the second speed reducer are realized by tensioning devices. The first speed reducer and the second speed reducer are in a closed-loop connection. The planet gear speed reducer enclosed type experiment bench has advantages of high mechanical transmission efficiency, small power consumption, stable performance, and abilities of solving bottlenecks of domestic walking and winch speed reducer experiments, facilitating improvement of product performance and quality of speed reducers, and breaking through dependency of domestic engineering machinery factories on oversea products.

Description

technical field [0001] The present invention relates to the technical field of planetary gear reducers, and more specifically, relates to a closed test bench for planetary gear reducers. The reducer is mainly used in wire rope hoists and crawler-type walking machines. Background technique [0002] The current domestic test bench experiment system is mainly an open test bench, which has a large energy loss, a single test reducer, and it is impossible to conduct experiments on two devices at the same time. For the travel reducer and winch reducer used in construction machinery, domestic technology still cannot reach the same level as foreign countries. Major construction machinery manufacturers still rely on foreign brands, and are currently developing related experimental systems and loading systems for domestic manufacturers' reducers. Quality is of paramount importance. [0003] At present, domestic transmission loading test benches can be divided into two categories: one ...

AI Technical Summary

Problems solved by technology

The mechanical closed power flow test bench has a large processing volume, a very complex mechanical structure, low mechanical transmission efficiency, and large energy loss. It is difficult to change the load during operation, and the torque is difficult to control.

The test performance is not stable enough and the versatility is poor, so it is decided to adopt the power return scheme
