Driving device used for new energy car motor rotor balancing machine

Abstract

The invention discloses a driving device used for a new energy car motor rotor balancing machine. A driving mechanism base is a vertical plate, an arc gap is formed in the upper portion of the drivingmechanism base, the position, on the arc gap, of the motor rotor balancing machine is horizontally supported and mounted through a supporting frame, a belt pressing-down assembly is movably connectedwith and mounted on the position between two sides of the upper portion of the driving mechanism base and crosses over the arc gap, a power assembly and a transmission assembly are arranged on the bottom of the driving mechanism base, the power assembly is connected with the transmission assembly, a driving arm clamping assembly and a belt tensioning assembly are arranged on the periphery of thearc gap, the transmission assembly, the belt pressing-down assembly and the belt tensioning assembly are connected through a belt, and the belt is pressed on a rotor. A wrap angle is increased, when arotor rotates, the large belt friction force can be obtained, slippage is avoided, the air inlet pressure of an air cylinder can be adjusted, the tensioning force of the belt can be adjusted, the belt can be compatible with a rotor with the large outer diameter range, and belts with different lengths do not need to be replaced.

Description

technical field [0001] The invention relates to a driving mechanism, in particular to a driving device for a new energy automobile motor rotor balancing machine. Background technique [0002] The development of new energy vehicles is a national strategy. With the support of national and local government supporting policies, my country's new energy vehicles have achieved leapfrog development in terms of industrialization and scale. At present, the new energy vehicles on the market are mainly electric vehicles. Electric vehicles are powered by an electric drive system, and the electric drive rotor is the core component. [0003] The electric drive rotor market is huge and has a bright future. In the mass production process, due to the influence of materials and manufacturing processes, there is an initial imbalance. When the electric drive rotor with excessive unbalance works at high speed, it will cause vibration, noise, shorten life and even danger to auto parts. Therefo...
