Service HotlineThe side gear thrust washer used in the automobile differential is a flat washer, which is installed between the differential housing and the side gear to prevent the side gear from retreating. Due to the high-speed rotation of the side gear when the differential is working, it is necessary to ensure that the contact surfaces on both sides of the flat gasket are well lubricated.
The circuit board is often the circuit board that plays a major role in electrical equipment, and the main electrical components of the circuit are often integrated on the motherboard. For single-layer circuit motherboards, rivets are used on the circuit motherboard in order to make the components more firmly fixed on the pcb board. In the prior art, the rivets are all set on the circuit board by an automatic riveting machine, which is controlled by an internal program to automatically complete the rivet-setting operation. This internal program is pre-set. If you need to rivet different motherboards, you must change the internal program. If you need to temporarily rivet a circuit board, it will be cumbersome to change the program again. Moreover, this kind of automation equipment is produced on a large scale and is not suitable for temporary operations.
Since the sub-industrial revolution, electricity has been widely used in people's lives. The application and development of electric power liberates the social productive forces and improves the social production efficiency. It is indispensable to the progress of the society. As a necessary constituent element of electric equipment, screws play an important role in the field of electric equipment. Existing screws are composed of screw heads and studs, which require specific tools to be tightened. However, during the maintenance of electrical equipment, some high-altitude workers need to carry extra screws in order to tighten the screws. the tightening tool, the staff caused great inconvenience.
Copper nuts, also known as embedded nuts and inlaid copper nuts or plastic embedded nuts, are divided into hot-melt copper nuts, hot-pressed copper nuts, embedded copper nuts and ultrasonic copper nuts according to different methods of use. This product is widely used in mobile phones. Shell / Pen meter shell / injection part / insert of plastic part, used as an internal thread. Generally embossed on the outer circle. To prevent sliding.

Moisture-proof measures Iron screws are easy to rust in a humid environment. In order to prevent the screws from rusting, the screws need to be moisture-proof and moisture-proof. The moisture-proof and moisture-proof methods of screws are as follows: (1) Vibration machinery, try to use solvent-free paint. (2) It is best to use impregnating paints that do not contain oxidative components, such as epoxy-urethane (Epoxy-urethane)-based or unmodified epoxy-based (Epoxy-)-based impregnating paints. (3) When using melamine alkyd impregnating paint, the curing temperature and curing time should be adjusted. The curing temperature should be slightly higher than 130 °C (such as 135 °C) and the curing time should be longer than 180min, and the process must be strictly implemented, especially In the hot and humid season, the drying (curing) time of the paint specified in the paint factory's samples is not necessarily sufficient from the perspective of rust prevention, and the motor has a specific inner shape. (4), use paint without volatile acid. (5) Choose paint with good hydrolysis resistance.
