Shunting type high-speed tester

Abstract

The invention discloses a shunting type high-speed tester, and belongs to the technical field of power equipment. The shunting type high-speed tester comprises a motor and a speed increaser, the speedincreaser comprises an input shaft, a first sun gear, a second sun gear, an output shaft and a plurality of planetary gear sets, and a planetary gear mechanism is adopted as a main part of the speedincreaser, so that the stability of power transmission is improved, power shunt and power confluence are realized, two-stage transmission is achieved accordingly, and the transmission ratio is increased; and meshing is achieved between the sun gears and planet gears through herringbone gear teeth, so that the transmission power of the planet gear mechanism is improved, and finally the output powerof the output shaft is improved. The combination of the planet gear mechanism and the herringbone gear teeth meets the requirement of the high-speed tester for high-speed and high-power output on thewhole.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a split flow high-speed tester. Background technique [0002] The high-speed tester is a special equipment that can convert the lower output speed of the motor into a higher output speed of the test piece. It is mainly used in aerospace and other industries that require high-speed rotation experiments. Existing high-speed testers generally use two methods to obtain a higher output speed of the test piece, one of which is to drive the test piece with a traditional speed increaser driven by an electric motor. Although the traditional speed increaser can increase the speed of the test piece within a certain range However, the speed increase is limited, the transmitted power is small, and the transmission stability is low, which cannot meet the high speed and high power requirements of the high speed tester. The other is to directly drive the test piece by a high-speed motor...

Problems solved by technology

Existing high-speed testers generally use two methods to obtain a higher output speed of the test piece, one of which is to drive the test piece by a traditional speed increaser driven by an electric motor. Although the traditional speed increaser can increase the speed of the test piece within a certain range However, the speed increase is limited, and the transmitted power is small, and the transmission stability is also low, which cannot meet the high speed and high power requirements of high speed testers.

The other is to directly drive the test piece by a high-speed motor. The high-speed motor is not only expensive to manufacture, but also limited by the speed and power, which cannot meet the needs of high-speed and high-power testers.
