Experimental apparatus for dynamic performances of cylindrical gear

Abstract

The invention discloses an experimental apparatus for the dynamic performances of a cylindrical gear. The apparatus comprises a precision lathe bed and a precision spindle unit. A spindle unit, a torque sensor and a motor are fixed on a drive-end box body. A driven shaft spindle unit, a torque sensor and a loader are fixed on a load-end box body. A gear clamp and a spindle are connected via a lolley needle. In this way, the installation of gears is facilitated, and the gear clamp is ensured to be good in interchangeability. Meanwhile, the dimension range of experimental gears is enlarged. The experimental apparatus is provided with multiple sensors, thus integrating mechanical functions, optical functions and electrical functions as a whole. The experimental apparatus enables various common experiments on cylindrical gears, such as the measurement on the transmission error profiles of gears, the analysis on the meshing vibration noises of gears, the measurement on the contact spots of gears, the measurement on the transmission efficiencies of gears and the like. The experimental apparatus is high in precision, large in rigidity, extremely good in stability and high in degree of automation, which can meet the requirements of dynamic and static tests on gears.

Description

technical field [0001] The invention relates to a cylindrical gear dynamic performance experiment device, which is especially suitable for the performance experiment of cylindrical spur gears and cylindrical helical gears in automobile gearboxes, as well as the dynamic performance experiments of cylindrical gears with similar dimensions below grade 5 precision, and belongs to the field of precision measurement. Background technique [0002] Gears and gear transmissions are widely used in mechanical equipment as an indispensable universal component for connecting and transmitting power. Due to the requirements of high performance, high strength, high reliability and low cost, in recent years, in the theoretical analysis of gear transmission, in addition to the new achievements of applied mathematics, mechanics, materials and design theory, the gear experimental device has also been further improved.

Problems solved by technology

[0003] Traditional gear test devices are mostly fatigue test devices. This type of gear test device has high strength, high energy consumption, low precision and low degree of automation. Gear noise experiments and contact spot tests are all done by manpower. Such experimental results are highly subjective and cannot be completely objective. Evaluation of gear meshing performance

The current gear experimental device has a single function, and there is no experimental device that can comprehensively evaluate the performance of gear transmission error, gear vibration and noise, gear transmission efficiency and contact spots.
