Method for measuring flatness of belt wheel of air conditioner electromagnetic clutch belt wheel under different loads

Abstract

The invention discloses a method for measuring the flatness of an air conditioner electromagnetic clutch belt wheel under different loads. A detection device is prepared, and comprises a pedestal, a mounting seat, a high-tension load loading system and a relay; the high-tension load loading system comprises a back plate, a linear motor, a pull rod seat, a sliding rail and a sliding block; theback plate is fixedly arranged on thepedestal; the sliding rail is fixedly arranged on the upper portion of the back plate, the sliding block can horizontally slide on the sliding rail, the dial indicator seat is arranged on the sliding block, the dial indicator seat and the sliding block synchronously horizontally slide, the dial indicator seat clamps the dial indicator, the linear motor can horizontally move on the back plate, the pull rod seat is connected with the linear motor and synchronously horizontally move along with the linear motor, and the pull rod seat is connected with the belt wheel. The linear motor applies load to the belt wheel through the pull rod seat. The measuring method comprises the following steps that the driving wheel, the belt wheel and the dial indicator seat are arranged to finish initial flatness measurement of the belt wheel; the transmission wheel and the belt wheel are connected through a belt, a load is applied to the tested clutch belt wheel, the sliding block is pushed, the flatness of each level is measured through the dial indicator, the load is changed, and the measurement is repeated.

Description

technical field [0001] The invention relates to the technical field of electromagnetic clutches, in particular to a method for measuring the flatness of pulleys of air conditioner electromagnetic clutches under different loads. Background technique [0002] The electromagnetic clutch of automobile air conditioner is usually composed of three parts: pulley combination, armature assembly and electromagnetic coil assembly. The pulley is a power transmission part connected with the transmission wheel of the automobile engine. The pulley rubs against the friction surface of the armature through the friction surface. Realize the disconnection and connection of the compressor or other power devices and the engine belt. The flatness of the friction surface directly affects the magnitude of the friction force. However, after the friction surface is subjected to tension from the pulley, the friction surface deforms. There are four poles or six levels of electromagnetic force distribut...

Problems solved by technology

[0003] The conventional measurement method in the prior art is to use a flatness detection device to measure the flatness of the components in a static state, and it is impossible to grasp the real-time changes in the flatness of the transmission wheel when the transmission wheel is in motion and under different loads.
