The reasons for the shortened life of the vibration motor are as follows: 1 Burnt due to vibration motor overload, short circuit, overcurrent and phase loss. This is a relatively common phenomenon of burning. 2 The loosening of the anchor bolt causes the motor to burn out. Since the excitation block at both ends of the vibration motor generates excitation for nearly 3,000 times per minute, the anchor bolt is continuously impacted, and the vibration motor itself is also involved in the vibration, so the anchor bolt is very easy to loose or even break, thereby burning the motor. . 3 Damage to the motor caused by improper installation. Because the vibration motor is equipped with a heavier excitation block − eccentric iron at both ends; if the motor is installed vertically or obliquely, then the shaft is vertical or inclined, then the bearing will bear the gravity of the excitation block in the axial direction, Bearings have an adverse effect, which shortens the life of the motor. 4 Damage to the motor caused by poor sealing of the protective cover. Due to the harsh working environment of the vibration motor, the dust is large. If the protective cover is not tightly sealed, the dust can easily enter the inside of the cover, causing the frictional block to operate, thereby burning the motor. 5 Influence of high ambient temperature on the motor Because the vibration motor and the warehouse wall are rigidly connected, it can also be said to be a whole. If the temperature of the material in the warehouse is too high, it is easy to cause the temperature of the vibration motor base and the casing to increase, which causes heat dissipation and thus the motor is destroyed. 6 bad heat dissipation causes motor damage The fan is equipped with a fan blade at the end of the motor, which not only dissipates heat quickly, but also removes the dust that falls on the casing, so that the motor is always working in a good state. The vibration motor is not equipped with a cooling fan, which relies on natural cooling. In addition, the working environment is harsh, the dust is large, and the dust is easily accumulated on the surface of the motor , causing the internal temperature of the motor to rise and burning the motor. 7 Damage to the motor caused by improper maintenance. In the maintenance and installation of the vibration motor, the direction of the excitation block at both ends is sometimes reversed, so that a space torque is generated when the motor is running, and the vibration motor is operated in an abnormal state, thereby causing damage.

Non-tapping screws are machine Screw, the pieceworker to be fastened must be tapped with taps in the screw hole in advance to match the screw threads.
The difference between tooth screws and other screws depends on whether they can be used together with nuts. Tooth screws can be used with nuts. And relative to the screws of other teeth, there are self-tapping screws. The nut of this kind of screw has no bow teeth. As for the standard teeth and fine teeth are only different pitch, it is the nut of the machine screw
