Embodiment Construction

[0031] This embodiment is a simulation test device for accelerated wear of the fastening bolts of the ceiling fan; the speed of the ceiling fan is controlled by the servo motor driver to simulate the accelerated wear test of the fastening bolts under accelerated conditions; by adding weights, the fastening bolts under severe working conditions are simulated. The accelerated wear test of solid bolts can greatly increase the speed without changing the wear mechanism, so as to achieve the purpose of accelerating the wear law test.

[0032] refer to figure 1 , figure 2 , image 3 , the simulation test device includes a test frame 1, a motor 2, a servo motor driver 3, and a slide assembly, which also includes a test ceiling fan 8, a guide rod 12, a motor transition joint 5, a universal joint 6, a boom upper joint 7, and a torque limiter Sheet 9, belt 10, fastening bolts 22; test frame 1 provides support for other components; test frame 1 is a trapezoidal frame structure, the fou...

Abstract

The invention discloses an acceleration wear simulation testing device for a fastening bolt of a suspension rod of a ceiling fan. By utilizing the testing device, a wear law of a bolt of the suspension rod can be quickly obtained, and a testing period is shortened. The testing device is characterized in that a motor is mounted on a testing rack; a sliding seat assembly is fixed on a pedestal of the testing rack, a testing ceiling fan is connected with a motor shaft through a universal joint, a fastening bolt is mounted in a mounting hole in the lower end of the suspension rod, and a belt is sleeved on a shell of a rotor of a testing ceiling fan to limit the rotation of the rotor; a pulley is connected to a sliding seat through double lug plates, a steel wire rope is connected with the belt, and the other end of the steel wire rope bypasses the pulley and is connected with a weight. According to the testing device, a wear acceleration test of the fastening bolt under normal use conditions can be simulated by controlling the rotation speed of the ceiling fan by utilizing a driver; the wear acceleration test of the fastening bolt under serious working conditions can be simulated by adding the weight. During the testing process, the implementation of the wear acceleration test under the serious working conditions generated by the eccentric weight can be simulated by deflecting a machine head of the ceiling fan; a double-acceleration wear test can be realized by simultaneously accelerating the rotation and applying the serious working conditions.

Description

technical field [0001] The invention relates to an accelerated wear simulation test device, in particular to a ceiling fan suspender rod fastening bolt accelerated wear simulation test device. Background technique [0002] At present, the suspension method of the commonly used ceiling fan product is to connect the suspension rod hanging from the ceiling with the motor shaft by fastening bolts. During the operation of the ceiling fan, the edges of the bolt holes of the suspension rod and the motor shaft produce fretting wear on the fastening bolt rod, and grooves are formed on the bolt rod, which may cause the bolt to break under long-term and high-strength use conditions , The head of the ceiling fan falls, causing serious accidents of personal injury. Therefore, it is necessary to explore the wear and damage laws of the fastening bolts of ceiling fan suspender rods through experiments, so as to provide quantitative basis for formulating ceiling fan product safety specifica...
