Test stand capable of adjusting installation errors for comprehensive performance of spiral bevel gears

Abstract

The invention discloses a test stand capable of adjusting installation errors for the comprehensive performance of spiral bevel gears. The test stand is characterized in that a variable-frequency alternating-current motor is mounted on one side of a base, a first spiral bevel gear case, a test gear shaft system, a second universal coupling, a first elastic coupling, a torque sensor, a second elastic coupling and a test assistant gear case are sequentially mounted in an anticlockwise direction, an output end of the test gear shaft system is connected with an input end of the test assistant gear case, an output end of the test assistant gear case is connected with a first output end of a second spiral bevel gear case by a third elastic coupling, a first shaft and a fourth elastic coupling, an input end of the second spiral bevel gear case is connected with an output shaft of a direct-current motor by a second clutch, and a second output end of the first spiral bevel gear case is connected with a second output end of the second spiral bevel gear case by a fifth elastic coupling, a hydraulic loader, a sixth elastic coupling, a second shaft and a seventh elastic coupling. The test stand has the advantages that the test stand is provided with two power systems which respectively comprise the variable-frequency motor and the direct-current motor, and tests for the high-speed dynamic and low-speed stable performance of the spiral bevel gears can be independently completed.

Description

technical field [0001] The invention relates to a comprehensive performance test bench for spiral bevel gears, in particular to a comprehensive performance test bench for spiral bevel gears with adjustable installation error. Background technique [0002] Spiral bevel gears are widely used in machines and equipment such as automobiles, tractors, aircraft and construction machinery due to their advantages of large load capacity, stable transmission, low noise and compact structure. With the advancement of science and technology, the improvement of the quality of life and the strengthening of human awareness of environmental protection, people have put forward higher requirements for the smooth operation of machinery, and low-noise machinery is very popular. As an important transmission component, the comprehensive performance of the spiral bevel gear is one of the important factors affecting the performance parameters of the whole machine system, so the comprehensive performa...

Problems solved by technology

[0004] CNC spiral bevel gear testing machines such as 600HTT produced by Gleason and TZO produced by Klingelnberg can perform relatively good dynamic comprehensive performance tests on spiral bevel gears. It is difficult to meet the requirements, which makes it impossible for many manufacturers of spiral bevel gears to objectively evaluate the quality of the bevel gears they produce. The sound level meter conducts running noise detection and other lagging levels, and then relies on the experience of the measurement personnel to make qualitative evaluations on the measured contact area shape and noise level
